  • Christos Alexakis, Giulio Anselmi, Giovanni Petrella (2024) Flight to cryptos: Evidence on the use of cryptocurrencies in times of geopolitical tensions. International Review of Economics & Finance, Volume 89, Part A, 2024, pp 498-523

This paper examines trading activity in cryptocurrencies in times of geopolitical crises. Cryptocurrencies represent speculative assets as well as payment methods. This combination of features is not present in securities like stocks and bonds. The empirical analysis is based on a sample of 93 events associated to potential limitations of a fiat currency circulation and considers five cryptos (Bitcoin, Ether, Ripple, Dash, and Tether). We find that trading in cryptocurrencies increases with events of geopolitical tensions. The increase in cryptocurrencies trading in times of crises can be motivated by different explanations (e.g., protecting savings as the domestic currency devaluates, making payments as the domestic financial system is no longer available, avoiding sanctions) which are difficult to disentangle. A more specific analysis concerning the EU sanctions established in 2022 on Russia shows that crypto trading slows down when crypto-related services (wallet, account or custody services) are explicitly included in EU financial sanctions packages. A warning about data limitations: the data set only includes trading activities conducted on centralized exchanges (CEXs) and does not include transactions conducted on decentralized exchanges (DEXs). Sanctions are supposed to be more effective on CEXs where the platform acts as a custodian for trader’s asset. We also examine trading activity from the Ukranian Hrvynia to cryptocurrencies and find a strong increase in outflow from Hrvynia since the beginning of the conflict. This finding – which is not affected by donations of cryptos received by Ukraine from abroad – is consistent with the hypothesis that Ukrainians increasingly exchanged their domestic currency for cryptocurrencies.

  • Tanveer Ahsan, Bakr Al-Gamrh, Muhammad Azeem Qureshi & Ammar Ali Gull (2024) Does eco-innovation foster or hinder environmental performance? Recent evidence from Europe, International Journal of Green Energy, volume 21 issue 2, pp.205-215

This study investigates the impact of country-level eco-innovation policies on the environmental performance of European firms. As different industries are expected to produce more pollution, the study then explores the impact on the firms operating in sensitive industries. We use fixed effects panel data models to examine 1,098 firms listed in 22 European countries from 2010–2018. Our results indicate that country-level eco-innovative policies provide an encouraging environment for European firms to adopt environment-friendly practices. Eco-innovation policies help firms achieve CO2 targets and mitigate climate change which supports the product stewardship theory. Our results also suggest that larger, more profitable, and low debt-financed European firms have better environmental performances. We also find a moderating impact of industry sensitivity and make an intriguing discovery that country-level eco-innovation policies hinder the environmental efforts of the firms operating in sensitive European industries. These results are robust to different proxies of eco-innovation and endogeneity issues due to reverse causality.

  • Muhammad Azeem Qureshi, Ammar Ali Gull, Tanveer Ahsan, Muhammad Ansar Majeed (2024) Do firms walk the talk when economic uncertainty is high? Journal of Cleaner Production, Volume 436, 140617

The growing influence of stakeholders and unprecedented emphasis on corporate social responsibility (CSR) have significantly changed the way firms operate. To seek legitimacy from stakeholders, firms might implement CSR measures in true essence while others might turn to CSR decoupling (i.e., higher CSR disclosure than performance), which is detrimental to the firm and stakeholders, specifically when facing high economic uncertainty. Using a large dataset of U.S. firms listed between 2002 and 2019, we examine how economic policy uncertainty (EPU) impacts CSR decoupling. Our findings show that EPU and CSR decoupling are positively and significantly associated, suggesting that firms do not walk the talk when economic uncertainty is high. These results expand legitimacy theory by suggesting that corporations use CSR disclosure as a façade to seek legitimacy from stakeholders when faced with high uncertainty. Interestingly, female directors, who are associated with higher ethicality, acquit themselves well when uncertainty is high: gender-diverse boards play a significant role in moderating policy uncertainty’s adverse impacts on CSR decoupling. These findings are robust to different regression models, subsample analysis, and endogeneity issues.

  • Umar Farooq, Bakr Al-Gamrh, Jiapeng Dai (2024) Green drives greenbacks: The impact of sustainable innovation on corporate cash holdings in BRICS nations. Journal of Cleaner Production, Volume 436, 140533

This study delves into the impact of sustainable innovation on corporate liquidity, specifically examining its influence on cash holdings among companies listed in BRICS nations. The study also explores the impact of green innovation on cash holdings before and after COVID-spread. Utilizing the system GMM regression technique on data spanning 2010 to 2022, we scrutinize the relationship between green innovation and cash reserves. Our findings reveal a significant correlation, showcasing that companies actively engaged in sustainable practices maintain lower levels of cash. This suggests a tangible reduction in the necessity for large cash reserves among businesses prioritizing green innovation. Notably, this effect persists even in the post-COVID landscape, highlighting the resilience of sustainability efforts on financial strategies. The influence of green innovation on cash holdings remains robust with diverse firm-specific and macroeconomic variables. The implications underscore the dual benefits of sustainable innovation, contributing not only to environmental sustainability but also enhancing financial efficiency by minimizing excess cash holdings. This study accentuates the imperative of integrating sustainability considerations into financial decision-making, offering practical insights for firms seeking to align sustainability goals with effective financial management. It provides valuable insights for policymakers and investors interested in promoting and supporting green initiatives. This study contributes to the evolving discourse on sustainability and corporate finance by shedding light on a relatively unexplored aspect of the association between green innovation and financial strategies

  • Guanghui Zhou, Dengyuhui Li, Junsong Bian, Yixiang Zhang (2024) Airfreight forwarder’s shipment planning: Shipment consolidation and containerization. Computers & Operations Research, Volume 161, 106443

This study focuses on an airfreight forwarder’s shipment planning problem, while considering shipment consolidation and containerization in the international supply chain. Items belonging to different shipments from supplier’s manufacturing warehouses are consolidated and loaded into Unit Loading Devices (ULDs) at outbound logistics hubs and to inbound logistics hubs by air transportation, where items are unloaded from the ULDs and distributed to the corresponding retailers by parcel delivery. A three-dimensional multiple bin size bin packing problem is considered, where items are consolidated and orthogonally loaded into ULDs of heterogeneous irregular shapes, where each item has a required latest allowable delivery time. A mixed integer programming model is formulated for the problem, which aims to determine the optimal route planning and feasible packing scheme for the transported items. This study develops a biased random-key genetic algorithm combining a three-dimensional bin packing heuristic to solve the problem. A two-phase greedy heuristic with a chaotic system is designed for the generation of initial population. Additionally, a catastrophe operator and a self-adaptive neighborhood search are put forward to further improve the performance of the algorithm. A numerical experiment is given to demonstrate the feasibility of formulation and effectiveness of algorithm by comparing with ILOG CPLEX, and managerial insights are provided.

  • Descubes, I., Hennekam, S. (2024) Why common job demands are challenging for individuals with mental illness: the interaction of personal vulnerability factors and ableist norms. Equality, diversity and inclusion: An international journal. Vol. 43 No. 1, pp. 72-92

Drawing on the job demands-resources (JD-R) model, this study aims to examine which job demands individuals with diagnosed mental illness perceive to be most challenging as they navigate the workplace, why this is the case and which resources individuals tend to mobilize to meet these demands. The authors draw on 257 qualitative surveys filled out by individuals with mental illness in various parts of the world. The findings show that job demands that are common in today’s workplace such as a high workload and a stressful environment are considered challenging by individuals with mental illness. Further, the authors show that this is the result of the ideal worker norm consisting of the need to be a steady performer that is confident, resilient and social with which the performer cannot comply on the one hand and the particularities of this population, such as performers’ self-perceived low self-esteem, sensitivity to stress, fluctuating symptoms and difficulties with the social aspects of organizational life on the other hand. The study points to the unique challenges of individuals with mental illness in the workplace and highlights the role human resource management (HRM) can play in providing support to allow this population to meet the demands of one’s job more easily and thrive at work

This study contributes to knowledge on the so far limited understanding of how to manage collaboration between Social Internet of Things (SIoT) service robots and consumers in the retail context. Embedded in Computers Are Social Actors (CASA) paradigm, we leverage a Partial Least Approach – Structural Equation Modelling (PLS-SEM) (n = 356) to show that word of mouth, consumer promotion experience, relationship quality, and inspiration significantly impact consumers’ repeat purchase intention when SIoT robots are used. Noticeably, while relationship quality is significant, it has a negative coefficient indicating that consumers may have high pre-existing anxiety towards SIoT service robots.

  • Rabeb Riahi, Amel Bennajma, Abderrahmane Jahmane, Helmi Hammami (2024) Investing in cryptocurrency before and during the COVID-19 crisis: Hedge, diversifier or safe haven? Research in International Business and Finance, Volume 67, Part B, 2024, 102102

This paper examines the safe-haven, diversification, and hedging properties of cryptocurrencies against stock market declines. We use daily data for two sub-periods: pre-Covid-19 and during Covid-19. The sample includes the stock market indices of the 10 countries most affected by the pandemic and the eight most popular cryptocurrencies based on their market capitalization over the study period. We found that Bitcoin, Cardano, Ethereum, and Binance have generated portfolio diversification benefits for investors during the Covid-19 outbreak, while Tether and the USD Coin have acted as safe-haven assets. Additionally, the findings reveal that gold has been an effective diversification tool for investors during the Covid-19 pandemic, while West Texas Intermediate (WTI) crude oil has positively impacted stock index returns. Our results are of great practical interest to academics and policymakers, as well as investors, and provide relevant information on cryptocurrency variations during times of crisis.

Les recherches sur la manière dont les évaluations cognitives de multiples signaux de défaillance d’un service se combinent pour générer la colère du client et le rôle des stratégies de régulation émotionnelle (suppression et réévaluation) dans l’atténuation de cette émotion sont encore rares. En utilisant une méthode expérimentale de vignettes d’une situation de défaillance de service auprès de 971 participants, nous montrons que les évaluations cognitives du blocage des objectifs, de la responsabilité d’autrui et du faible contrôle agissent conjointement, de manière indifférenciée, pour augmenter la colère de façon non linéaire. Nous démontrons également que la suppression émotionnelle est bénéfique pour faire face à la colère dans des situations où plusieurs signaux provoquent la colère. Inversement, la réévaluation est plus efficace lorsque les signaux déclencheurs de colère sont moins nombreux. Ce résultat remet en question le point de vue dominant selon lequel la réévaluation est préférable à la suppression pour faire face aux émotions négatives.

  • Kerr, R., Robinson, S., Sliwa, M. (2024) Organising populism: from symbolic power to symbolic violence. Human Relations, Volume 77, Issue 1, January 2024, Pages 81-110

This article contributes to developing a management and organisation studies perspective on political organising by focusing on: (a) populism; (b) the exercise of political power; and (c) the organisation of politics. We address two questions: in what ways have English populist politicians in the 20th and 21st centuries utilised language along with other aspects of campaign organising to build and enhance their symbolic power? And: how do populist political organisations convert symbolic power into symbolic violence? Drawing on a range of concepts from Pierre Bourdieu’s sociology, most specifically his work on symbolic power, symbolic violence, political ontology and the performativity of language, we conduct a comparative analysis of texts from four waves of right-wing English populism culminating in Brexit. We develop a three-step framework to explain the organisation of right-wing populism via what we term populist political methodology: (1) establishing the symbolic power of the leader and the message; (2) organising power and the division of labour of domination; and (3) reinforcing symbolic violence in targeted sections of society. Understanding how populist politics is organised can support us in resisting, challenging and disrupting right-wing populism, providing lessons for organisations campaigning against racism and xenophobia.

This article analyzes the relationship between project cost and time performance indicators and monitoring activities, namely, tracking frequency and regularity with real project data. The existing literature on project monitoring and control remains scant, mainly based on self-reported, simulation-based artificial data for a single project, and somewhat inconclusive. Data from 60 projects managed in Belgium between 2011 and 2019 with different project duration and sizes were first used to reveal associations of regular monitoring with project performance with linear probability models; then, to dissect nonlinear associations between monitoring frequency and project performance indicators using random effects models. Earned value management technique with performance indicators is adopted to assess the project performance. Empirical findings indicate that regularly tracked projects are less likely to be late. Tracking frequency displays a Ushaped association with the likelihood of late completion. Moreover, tracking frequency has inverted U-shaped relationships with cost performance and schedule performance indexes. Moving beyond the direct effects, this article is the first to analyze a nonlinear relationship between monitoring and project performance. Our results also validate prior studies’ findings on regular and frequent tracking effects using real-life multiple-project data and assess the EVM metrics and their behavior in project management.

  • J. Arsenyan and A. Piepenbrink (2024) Artificial Intelligence Research in Management: A Computational Literature Review. IEEE Transactions on Engineering Management, vol. 71, pp. 5088-5100, 2024

Artificial intelligence (AI) spring of the past decade created an increased interest into the topic in business as well as in academia. This resulted in an upward trend in academic publications, not only in computer science but also in management. This article presents a computational literature review with an abstract-based sampling approach to investigate the status of the management literature to take stock of academic research of the past two decades. We analyze 6324 papers from 1990 to 2020 published in five management-related domains and identify 41 distinct topics. We present the evolution of research pre and post AI spring, emerging topics as well as saturated areas. The findings show that the previously disjointed topic network structure is fully connected by early 2010s and the upward trend in management research starts in the period of 2014–2015. The results provide a comprehensive insight into the potential of AI in management versus underdeveloped areas, and presents, formanagement scholars and practitioners, suggestions about effective adoption of AI practices.

  • Tao, F., Zhou, Y., Bian, J., & Lai, K. K. (2024). Agency selling or reselling? Channel selection of green products with consumer environmental awareness. International Journal of Logistics Research and Applications, vol 27 issue 2, pp. 326-345

Motivated by the growing consumer interest in new energy vehicles, this paper studies a manufacturer’s pricing and channel selection issues when selling green products to environmentally conscious consumers. Three channel structures are examined: (1) a single agency selling channel, (2) a single reselling channel, and (3) dual channels of agency selling and reselling. Agency selling refers to the case in which the manufacturer directly sells products to consumers on the platform by paying a fixed fee. Reselling refers to when the manufacturer wholesales products to the platform, which is then responsible for selling to end consumers. We find that an increase in consumers’ green awareness has a positive impact on green technology levels, retail prices, and the profits of the manufacturer, platform, and retailer. When consumers’ green awareness and the revenue-sharing rate are relatively low, the manufacturer will choose the single reselling channel, which is beneficial for both the manufacturer and retailer. When consumers’ green awareness is moderate, the manufacturer will choose the hybrid channel in which the manufacturer and platform will reach a win-win situation. When consumers’ green awareness is high, the dual channel is simultaneously beneficial for the manufacturer, platform, and retailer, which reveals that Pareto optimisation occurs.

This study aims to measure the economic benefits of business mediation in Brazil compared to lawsuits, investigating whether choosing mediation to resolve a business conflict is more economically advantageous than filing a lawsuit in the judiciary and whether opting for extrajudicial mediation to settle a business dispute is more economically advantageous than reaching an agreement in judicial mediation. The research, conducted in the Southeast region of Brazil after the implementation of the Brazilian Code of Civil Procedure in 2016, employed quantitative methods, analyzing 397 judicial processes. The results indicated that extrajudicial mediation is the most cost-effective option, while the judicial lawsuit is the most costly. This article provides essential information for businesses to make informed decisions in the resolution of business disputes.

This article examines the relationships between research centers and related spin-offs. We identify a new incupportive model based on 41 interviews of 19 spin-offs from three research centers in Grenoble, France. This model complements the incubator and supportive model in the established literature, fostering knowledge transfer from research institutions (research centers) to business firms (spin-offs) for innovation. It also helps spin-offs identify business opportunities, manage resources, and develop alliances and complementary activities. However, this new model generates potentially unfavorable outcomes, becoming counterproductive and hindering spin-off firms’ knowledge transfer. Our findings regarding the incupportive model’s positive and negative side effects enrich the spin-off literature and provide valuable practical implications for policymakers and entrepreneurs.

Retail stores often display large quantities of perishable products that they sell at full price over a given period and then at a discount until the end of the inventory cycle. We investigate this common practice by considering a product which is subject to continuous decay through time. The demand is a function of both the price of the product and the inventory level. The retailer may discount the product once during the cycle. Closed-form expressions were provided for the maximum discounting time and cycle time. The conditions under which an optimal discount policy exists were established. The results provide insights to decision-makers on how to design a markdown policy for perishable products.

  • Bakr Al-Gamrh, Tareq Rasul (2024) Recession-proof marketing? Unraveling the impact of advertising efficiency on stock volatility. International Review of Financial Analysis, Volume 92, 103087

The current study examines how corporate advertising efficiency (estimated using data envelopment analysis) is impacted during economic recessions. The study then investigates how advertising efficiency affects stock price volatility in recession and non-recession times. Drawing on the resource-based view and contingency theory, this study utilizes generalized method of moments (GMM) estimation to analyze a sample of US listed firms. The findings reveal that advertising efficiency tends to decline during economic downturns. Moreover, the study demonstrates that firms with higher advertising efficiency experience more stable stock prices during normal economic conditions. However, an interesting observation emerges during recessions, as firms with strong advertising efficiency face higher stock price volatility. This suggests that while consumers are attracted to efficient advertisements, investors do not assign the same value to advertising spending during economic contractions. Importantly, these results are robust to endogeneity issues and various measurements of variables.

  • Thomas Conlon, John Cotter, Emmanuel Eyiah-Donkor (2024) Forecasting the price of oil: A cautionary note. Journal of Commodity Markets, Volume 33, 100378

We study the out-of-sample predictability of monthly crude oil prices using forecast combinations constructed from several individual predictor forecasts. Our empirical results indicate that combination forecasts of monthly average oil prices are more accurate than the no-change forecast with statistically significant reductions in mean square forecast errors (MSFE) and significant directional accuracy at every horizon up to 24 months, consistent with earlier evidence that forecast combinations greatly enhance the forecastability of oil prices. In contrast, we find no significant MSFE reductions or directional accuracy for forecasts of end-of-month oil prices at almost all horizons. Furthermore, we document that end-of-month forecasts when used to guide investment and hedging decisions of investors, statistically, do not deliver superior economic value to investors. Overall, the implication of our results is that the statistical and economic significance of forecasts of oil prices is heavily influenced by the construction of the underlying oil price series and provide a cautionary note on which oil price series to use in forecasting.

Research on academic activism tends to foreground vociferous and explicit forms of activism that pursue predefined political agendas. Against this backdrop, this article proposes that academic activism can take more subtle forms. Writing as an academic activist collective, we unpack what subtle activism might look like within the context of contemporary academia. We use Foucault’s concept of heterotopia to argue that subtle activism can expand the space of what is possible in academia today by experimenting with quietly unsettling norms rather than overtly opposing or rejecting them. We offer a set of principles that might underpin a subtle activist agenda, extrapolated from practices from colleagues and from own activist collective. We hope that these principles may serve to inspire other academics wishing to engage in subtle activism by unsettling everyday practices that discreetly challenge the status quo, thereby contributing to gently shifting the agenda for how it is possible to conduct intellectual work in the contemporary neoliberal university context.



  • Hu, H. Ma, J. Xiong, P. Gao and P. K. P. Divakaran (2024) Convergence or Divergence: A Computational Text Analysis of Stakeholder Concerns on Manufacturing Upgrading in China. IEEE Transactions on Engineering Management, vol. 71, pp. 1285-1295, 2024

Stakeholder participation is essential to the reasonable design and smooth implementation of industrial policies. Discourse analysis can be employed as a valuable methodology to decode stakeholder (dis)agreements. Following stakeholder theory, we examine four stakeholder groups, namely the government, enterprises, media, and academia, to analyze the public focus of industrial upgrading in China. We adopt a computational text analysis approach (keyword frequency calculation, word collocation analysis, and theme identification) to understand the divergent and convergent stakeholders’ concerns toward manufacturing upgrading in China from 2015 to 2020, which is widely considered as a manufacturing upgrading policy formulation stage. Our results show that stakeholders mainly focus on innovation capability and digital transformation for China’s manufacturing upgrading. There, industrial planning is the major issue for government and academia. Contradistinctively, enterprises’ main concern is servitization. Enterprise internationalization is more frequently mentioned than manufacturing upgrading in the media industry. Policymakers should engage in various tactics to make the policies endorsed by other stakeholders.Most importantly, the government should fully integrate the views of entrepreneurs in the policy initiation stage. We provide practical implications for the Chinese government to implement better the Made in China 2025 plan

  • Mahdi Ghaemi Asl, Muhammad Mahdi Rashidi, Hamid Raza Tavakkoli, Hichem Rezgui (2024) Does Islamic investing modify portfolio performance? Time-varying optimization strategies for conventional and Shariah energy-ESG-utilities portfolio. The Quarterly Review of Economics and Finance, volume 94, 2024, Pages 37-57

This paper aims to assess the performance of Islamic portfolios vis-`a-vis their conventional counterparts across two distinct periods: the pre-COVID-19 era and the COVID-19 era. Departing from prior studies, this study makes a novel contribution by employing an extensive array of 18 portfolio optimization techniques to construct optimal portfolios for conventional stock indices encompassing energy, utilities, and environmental, social, and governance (ESG) dimensions, as well as their Islamic equivalents. Performance comparisons are made utilizing three risk-adjusted performance measures, namely the Sharpe ratio, the Omega ratio, and the Sortino ratio. Our findings reveal that Shariah portfolios outperform conventional portfolios across all performance measures and risk-aversion levels when the most effective optimization methods are employed, both during pre-crisis and crisis periods. Additionally, our analysis highlights certain methods, namely EWMA, GM, DCC, and SHC, which produce portfolios exhibiting superior performance relative to alternative methods, as assessed by risk-adjusted metrics. Furthermore, Islamic portfolios demonstrate higher average returns compared to their conventional counterparts. Notably, incorporating ESG-related stocks into energy and utilities assets significantly enhances average returns, underscoring the potential of ESG investments. Collectively, our findings have noteworthy implications for investors, as they emphasize the role of Islamic stocks as effective diversifiers, yielding favorable resource allocation opportunities during times of crisis as well as stability. However, investors should exercise caution in selecting the optimal portfolio optimization method, as substantial performance disparities exist among different approaches.

  • Zhimei Luo, Jinyuan Guo, Jose Benitez, Laurent Scaringella, Jiabao Lin (2024) How do organizations leverage social media to enhance marketing performance? Unveiling the power of social CRM capability and guanxi. Decision Support Systems, Volume 178, 2024, 114123

Drawing on information technology-enabled organizational capabilities theory, we argue that how and when social media use affects marketing performance depending on the mediating role of social customer relationship management (CRM) capability and the moderating role of guanxi. Using a sample of 194 Chinese agricultural firms, we employed a combination of complementary techniques: advanced analysis for composites–structural equation modeling (ADANCO-SEM) and fuzzy-set qualitative comparative analysis (fsQCA). In ADANCO-SEM analysis, we empirically verify the full mediating role of social CRM capability in the association between social media use and marketing performance and identify the condition for this indirect effect (i.e., when the guanxi levels are high). Moreover, guanxi plays a dual moderating role—it exerts a substitution effect when social media is used to build social CRM capability, and it exerts a complementary effect when social CRM capability is leveraged to improve marketing performance. FsQCA analysis further reveals the different configurations of social media use, guanxi, and social CRM capability that can lead to high marketing performance in different firm sizes. The findings complement those from ADANCO-SEM analysis vis-`a-vis the conditions for the formation of marketing performance. This study contributes to the emerging literature on the business value of social media by theoretically exploring and empirically validating the mechanisms and boundary conditions by which social media affects marketing performance.



  • Chenchen Yang, Junsong Bian, Xiaolong Guo, Wenwen Jiang (2024) Logistics outsourcing strategy with online freight platforms, Omega, Volume 125, 2024, 103042

Online Freight Platforms (OFPs) are emerging and developing rapidly based on the Internet of Things and big data technologies. They provide professional logistics services by aggregating the scattered transportation capabilities of individual truck drivers. OFPs have become increasingly popular compared to Traditional Logistics Service Providers (TLSPs), and OFPs have integrated more than 20% of the truck drivers in China. In this paper, we study a manufacturer’s production, distribution, and transportation of a product in bulk to a downstream firm via two transportation channels: TLSP and OFP. The two channels offer different operational modes, service levels, and contract prices. We develop a game-theoretical model to analyze the strategic interactions among the manufacturer, transportation service provider, and downstream firm. Our study highlights the implications for the manufacturer’s logistics outsourcing strategy with OFP and TLSP operations. We find that when an OFP is available, differences in transportation service levels and prices significantly affect the equilibrium decisions of the manufacturer and TLSP. Surprisingly, the emergence of OFPs does not necessarily threaten TLSP operations. This study provides guidance to manufacturers about their selection of shipping outsourcing strategies and new guidance for TLSP operations considering the emergence of OFPs.

China is a collectivist nation that varies socially and culturally from most Western countries. Recently, the country has been an attractive destination for international students.  A contemporary digital platform such as WeChat Moments (WMs) is a leading social media platform among locals and international students to communicate and interact in cross-cultural settings for various purposes, including maintaining friendships and establishing new social capital. Prior research has overlooked the beneficial effects of such domestic social media platforms on international students in China, especially for strengthening their existing friendship quality and guanxi network ing.Based on the self-disclosure theory, this study examines the relationship between international students’ WMs use intensity, online self-disclosure, closeness to friends, and guanxi network building using data from 445 international students employing structural equation modeling. This study reveals that WMs use has a substantial effect on the formation of guanxi networks and that online self-disclosure mediates the connection between WMs use and friendship closeness and guanxi network building. Several theoretical and practical recommendations are provided in the context of the guanxi network.

This study aims to examine the role of message appeals (concrete vs abstract) posted by greenfluencers in determining their behavioral intention toward the sponsored sustainable product. This study examined the underlying mechanism of message authenticity and product sustainability image in this relationship. This study also investigated the boundary condition of product type (utilitarian vs hedonic) in the effect of sustainability message appeal on purchase intention. Four studies were carried out. One field experiment on Facebook and three scenario-based online experiments were conducted to test the proposed relationships. This study found that a concrete message appeal results in a higher purchase intention of the promoted product than an abstract message appeal. This effect is a result of message authenticity and product sustainability image. Furthermore, product type moderates the impact of message appeal on behavioral intention via message authenticity and product sustainability image. This study contributes to the literature on influencer marketing, sustainability communication and the persuasion process. Practical implications – This study’s findings provide insights  for greenfluencers and firms that leverage greenfluencers to promote their sustainable products on social media. Specifically, it lays out how the sustainability message should be framed to be persuasive. This study findings offer novel insights for greenfluencers and firms in developing effective message strategies to promote sustainable products on social media.

Identifying key drivers of manufacturing CO2 emissions is critical to carbon reduction practices. For manufacturing, CO2 emissions are mainly determined by production capacity and production scale. However, traditional production-theoretical decomposition analysis (PDA) fails to consider production-scale-related drivers. To better support policy development and implementation, this paper improves PDA based on industrial linkage theory. The improved model can identify seven production-capacity-related drivers and five production-scale-related drivers, allowing a comprehensive understanding of CO2 emission drivers. Then this model is implemented to investigate CO2 emission changes in 18 manufacturing sectors in Hubei Province, China, from 2012 to 2017. Results show that manufacturing CO2 reduction efforts in Hubei Province have yielded some achievements, with reduced potential energy intensity and improved CO2 emission technical efficiency in most sectors. Changes in external market demand and final demand structure have contributed to CO2 reduction in most sectors. Results also reveal some problems in manufacturing in Hubei Province, such as the inability to improve CO2 emission technical efficiency and CO2 emission technology strength, the slow improvement of energy utilization technical efficiency and energy utilization technology strength, and the reduction of value-added rate.

  • Hennekam, S., Richard, S. & Ozbilgin, M. (2023). How social structures influence the labour market participation of individuals with mental illness: A Bourdieusian perspective. Journal of Management Studies, Volume 60, Issue 1, January 2023, pp 174-203

Adopting a Bourdieusian perspective, this paper examines the social structures that influence the labour market participation of individuals with mental illness. We draw on 57 qualitative surveys completed by individuals with diagnosed mental health conditions in Europe, North America, Oceania, Africa, and Asia. We employed thematic analysis to analyse the data. The findings reveal that the interplay of capital endowments, symbolic violence, habitus and illusion shape the labour market participation of individuals with mental illness. Capital endowments of individuals with mental illness are afforded less value in the labour market and these individuals internalize, legitimize and normalize their disadvantaged position, blaming themselves rather than questioning the social structures leading to the challenges they encounter. We highlight that social structures condition the opinion these individuals have of themselves and how this affects how they navigate the labour market. In sum, we show that Bourdieu’s concepts provide a useful lens to study inequalities in the labour market, as they reveal the social structures that produce, sustain and reinforce the social order that disadvantages individuals with mental illness.

  • Hudson, S. and  Liu, Y (2023) Mobile App Users’ Privacy Concerns: Different Heuristics for Privacy Assurance Statements in the EU and China. Information Technology & People. Vol. 36 No. 1, 2023, pp. 245-262

As mobile apps request permissions from users, protecting mobile users’ personal information from being unnecessarily collected and misused becomes critical. Privacy regulations, such as General Data Protection Regulation in the European Union (EU), aim to protect users’ online information privacy. However, one’s understanding of whether these regulations effectively make mobile users less concerned about their privacy is still limited. This work aims to study mobile users’ privacy concerns towards mobile apps by examining the effects of general and specific privacy assurance statements in China and the EU. Drawing on ecological rationality and heuristics theory, an online experiment and a follow-up validation experiment were conducted in the EU and China to examine the effects of privacy assurance statements on mobile users’ privacy concerns. When privacy regulation is presented, the privacy concerns of Chinese mobile users are significantly lowered compared with EU mobile users. This indicates that individuals in the two regions react differently to privacy assurances. However, when a general regulation statement is used, no effect is observed. EU and Chinese respondents remain unaffected by general assurance statements. This study incorporates notions from fast and frugal heuristics end ecological rationality – where seemingly irrational decisions may make sense in different societal contexts.

Voluntary carbon offset (VCO) programs give air travelers opportunities to neutralize their carbon footprint. Despite its potential, few existing studies have explained how to present VCOs that can effectively appeal to the sensibilities of travelers in different conditions. We designed three online experiments with strategies to motivate travelers to opt-in. We found travelers who receive concrete messages that emphasize specific actions are more likely to opt-in to VCOs when flying in the near future. In contrast, travelers receiving abstract messages that emphasize general initiatives are more likely to opt-in to VCOs when flying in the distant future. When travelers are allowed to choose their preferred carbon offset method, they are more likely to opt in, especially when they receive concrete messages that indicate specific actions but not general initiatives. These findings contribute to the aviation carbon offset literature and offer useful new insights for airline companies.

  • Mahabubur Rahman (2023) The virtuous circle between green product innovation and performance: The role of financial constraint and corporate brand. Journal of Business Research, Volume 154, 2023, 113296

Although the nexus between green product innovation (GPI) and firm performance has been studied, the impact of GPI on firm performance remains little understood and findings have been mixed. These mixed results of prior studies are attributable to failures to incorporate the intervening mechanism in studying the nexus between GPI and firm performance and to examine the impact of closely interlinked pertinent internal boundary conditions. This study attempts to overcome these shortcomings and contributes to the relevant literature in three significant ways. First, the findings indicate that GPI impacts a firm’s financial constraint, which affects its current and anticipated performance. Second, the relationship between GPI and financial constraint is moderated by a firm’s corporate brand equity. Third, GPI is both a predictor and a consequence of financial performance, indicating that the relationship between the two constitutes a virtuous circle. The results are robust to alternative measures of the performance variable and the alternative model estimation method.

There are different opinions around the World regarding the zoonotic capability of H3N8 equine influenza viruses. In this report, we have tried to summarize the findings of different research and review articles from Chinese, English, and Mongolian Scientific Literature reporting the evidence for equine influenza virus infections in human beings. Different search engines i.e. CNKI, PubMed, ProQuest, Chongqing Database, Mongol Med, and Web of Knowledge yielded 926 articles, of which 32 articles met the inclusion criteria for this review. Analyzing the epidemiological and Phylogenetic data from these articles, we found a considerable experimental and observational evidence of H3N8 equine influenza viruses infecting human being in different parts of the World in the past. Recently published articles from Pakistan and China have highlighted the emerging threat and capability of equine influenza viruses for an epidemic in human beings in future. In this review article we have summarized the salient scientific reports published on the epidemiology of equine influenza viruses and their zoonotic aspect. Additionally, several recent developments in the start of 21st century, including the transmission and establishment of equine influenza viruses in different animal species i.e. camels and dogs, and presumed encephalopathy associated to influenza viruses in horses, have documented the unpredictable nature of equine influenza viruses. In sum up, several reports has highlighted the unpredictable nature of H3N8 EIVs highlighting the need of continuous surveillance for H3N8 in equines and humans in contact with them for novel and threatening mutations

Sustainable consumption has received much attention, although its antecedents are not fully elucidated. Existing studies are constrained by the assumption of symmetrical paradigms, emphasizing the net effects of antecedents without considering the complexity of sustainable consumption decision-making. This study draws on the theory of consumption values and the complexity theory to identify the complex combinations of consumption values (health, food safety, ecological, curiosity, novelty, prestige, avoidance of guilt) that explain consumers’ intentions to purchase plant-based meat alternatives (PBMA). An online survey was used to collect data from 252 meat eaters in the United States. Data were analyzed with fsQCA to identify the causal configuration of consumption values that explain meat-eaters’ PBMA purchase intentions. The fsQCA results revealed six heterogeneous combinations of the consumption values that result in high levels of purchase intention toward PBMA. The findings can be used by marketers to develop strategies for promoting sustainable consumption and PBMA.

Work–family balance practices available in several work organizations to help employees with children to manage the demands of work and family life can have a negative impact on employees with family commitments, on childless employees and on the organization itself, as Perrigino et al. show in their theoretical review. This is the work–family backlash phenomenon expressed by the four mechanisms of stigma, spillover, inequity and strategic. Even if the stigma mechanism towards working women with children was widely explored, no study until now considered the four backlash mechanisms jointly, in the Italian context. The purpose of this paper is offering a first empirical exploration of these mechanisms in Italian work organizations. For this study, 15 Italian career women with different care burdens were interviewed, and the four mechanisms were analysed from the perspective of women with and without children, and of organizations. Analysis has shown that the backlash phenomenon can trigger a vicious cycle of perceived inequity that leads to job dissatisfaction and low work motivation. Management responsiveness and fairness in dealing with employees’ needs are central to promoting well-being by effectively balancing career paths with personal needs, especially in a cultural context where most responsibility for family needs is still left to women and few public supports are available. This study, in spite of some limitations, offers a first contribution to the analysis of the different facets of the work–family backlash in the Italian context and suggests several possible research and practical developments.

  •  Mousa, S., & Bouraoui, T. (2023). The Role of Sustainability and Innovation in Financial Services Business Transformation. Theoretical Economics Letters, Volume 13, issue 1, pp 84-108

Purpose: This study discusses the effects of transformative service in the financial sector. Unlike conventional research, it reports how business transformation can play a vital role in human well-being. The main objective is to reveal how financial services can affect the welfare of people, communities, regions, and worldwide perspectives. Design/Methodology/Approach: The study used Confirmatory factor analysis and Structural Equation Modeling using SPSS (Amos). Findings: While appreciating the role of consumers as agents of service-driven business transformation, the study demonstrates how service transformation can promote an ecosystem that helps to accomplish rising sustainability goals. Originality: The main focus was to explain how social and environmental sustainability, responsible consumption and innovativeness are related to a firm’s attractiveness, value creation and customer satisfaction. Research Limitations: This study uses a cross-sectional survey design and it doesn’t have a holistic approach for all stakeholders. Predominantly, it considers the customer as a change agent in business transformation. Practical Implications: The study discusses a broader customer perspective instead of an extremely narrow and limiting traditional dyadic firm-customer perspective. It can enhance responsible production and consumption. It develops a comprehensive framework to help academicians, service leaders, and policymakers to recognize and solve service systems’ unsustainability. Social Implications: The research contributes to addressing, understanding, upgrading, and integrating the financial service system for business transformation, which can positively influence individuals and collectives.

Providing safe and adequate blood in an emergency to save many lives can be a challenge to the health system. In addition to managing blood collection in crises, delivering  blood to the crisis site in a timely manner is another important problem in decision-making. Hence, in this study, we present a bi-objective mathematical model for determining the routing of bloodmobiles and drones to collect blood from various blood group donors and apply a crossmatch strategy to supply adequate blood in critical situations. The first objective function is to maximize the amount of collected blood while the second objective function is to minimize the maximum arrival time of vehicles to the crisis-stricken city.We also introduce a function that determines the time required for bloodmobiles to stay in one place for the blood-collection process so as to bring the problem closer to real-world conditions. The problem is formulated as a two-stage stochastic problem by considering uncertainty in blood demands and the number of donors. To demonstrate the applicability and the efficiency of the proposed model, the model is tested on data from a real case study and implemented in various sizes viaCPLEX andMOPSO. Finally, the sensitivity analysis is performed on certain parameters. The results show that by adding bloodmobiles, the staying time of bloodmobiles in stations decreases, and the demands are met more rapidly. Also, for each drone added to the system that is responsible for transporting the collected blood to the disaster-stricken area, the amount of collected blood increases by 12% while the arrival-time of the last vehicle decreases by 46%. Therefore, this model can benefit decision-makers in times of crisis and the collection and timely delivery of blood to the crisis area

The significance of economic policies and their impact on corporate behavior and ecosystems are increasing in today’s interconnected world. The purpose of this study is to assess the impact of economic policy uncertainty (EPU) on waste generation by firms and the impact of gender diversity on corporate boards on the relationship between EPU and waste generation. The study contributes to existing research related to ecological economics by investigating the impact of EPU on the level of waste generated by firms in China, Europe, and the US. Using a dataset of 8007 firm-year observations from 2002 to 2019, we find overwhelming evidence that EPU increases the level of waste produced, both hazardous and non-hazardous. This finding supports the “shareholders’ wealth maximization” theory, which states that firms strive to safeguard shareholders during periods of high uncertainty. However, women directors, being more sensitive to sustainability, perform well on this front even during periods of high uncertainty, as the results show that gender-diverse boards significantly moderate the adverse impact of policy uncertainty on waste generation. However, the moderating impact of gender diversity is significant only for firms operating in environmentally sensitive industries. Our results are robust to different regression models, proxies for waste, and endogeneity issues.

The purpose of this paper is to examine the impact of corporate governance (hereafter, CG) reforms on the risk disclosure quality in an emerging economy, namely Pakistan. The authors also investigate the impact of CG reforms on the relationship between CG practices and risk disclosure quality. The authors use a manual content analysis method to a sample of nonfinancial companies listed on the PSX-100 index for 2009–2015, to examine the impact of CG reforms on risk disclosure quality. The authors use pooled ordinary least squares and the system GMM estimations to test the research hypotheses.
The authors find that CG reforms have a positive impact on risk disclosure quality. The results indicate that certain CG practices such as CEO duality and board independence are associated with risk disclosure quality. Interestingly, the findings also highlight the effectiveness of CG reforms by showing that the revised code positively moderates the CG practices and risk disclosure relationship. The findings of the study have policy implications for regulatory bodies of emerging economies trying to strengthen the CG structures and to introduce risk disclosure regulations to cater the information need of stakeholders.
The authors provide new empirical evidence for the impact of CG reforms on risk disclosure quality using a unique setting of an emerging economy, namely Pakistan.

We use a novel measure of firm-level political risk based on a textual search technique on firms’ quarterly earnings conference transcripts to explain dividend payouts in publicly listed U.S. firms. We find a positive and significant effect of firm-level political risk on dividend payouts, particularly in uncertainties related to economics, institutions, technology, trade, and security. The effect is more pronounced in firms with better corporate governance, less analyst follow-up, and higher growth opportunities. These results support the signaling role of dividends rather than the role of agency theory in explaining dividend payouts when firms are associated with higher levels of political risk. We also find the effect to be prominent after controlling for an aggregate measure of economic policy uncertainty and in poor economic conditions and in major political event periods. We address endogeneity concerns by running placebo tests and conducting instrumental variable analysis and we alleviate self-selection bias by performing propensity score matching technique.

This paper considers a platform-based supply chain consisting of a firm launching a new product with a targeted promotion strategy based on innovation on a retailing platform. We examine the firm’s optimal decisions on pricing, product quality design and promotional effort to deal with market uncertainty. First, with exogenous quality, we show that market size has a positive impact on the optimal effort level, which is contrary to the intuition that the optimal effort level decreases with the existing market size due to concave increasing costs. Furthermore, we study the scenario with endogenous quality but with exogenous price and find that the optimal effort level will decrease with market size if the market size is sufficiently large. Finally, with endogenous effort, price, and quality decisions, our result indicates that the firm exerts more efforts in such a platform-based targeted promotion than in the former scenarios when facing strict industry standards

This paper aims to investigate the effect of the Foreign Account Tax Compliance Act (FATCA) on the deposits held by US global banks through their branches located around the world. Using an unpublished dataset on deposits held by branches of US banks on a geographically unconsolidated basis, we find that the FATCA led to a reduction in deposits held in branches located in tax havens. We find that this effect is more severe in those jurisdictions signing a reciprocal exchange of information agreement. We also advance evidence in support of deposit shifting within the US banking system towards locations without a reciprocal intergovernmental agreement.

Due to the complexity and the magnitude of optimisation models that appeared in sustainable supply chain management (SSCM), the use of meta-heuristic algorithms as competent solution approaches is being increased in recent years. Although a massive number of publications exist around SSCM, no extant paper explicitly investigates the role of meta-heuristics in the sustainable (forward) supply chain. To fill this gap, a literature review is provided on meta-heuristic algorithms applied in SSCM by analyzing 160 rigorously selected papers published by the end of 2020. Our statistical analysis ascertains a considerable growth in the number of papers in recent years and reveals the contribution of 50 journals in forming the extant literature. The results also show that in the current literature the use of hybrid meta-heuristics is overtaking pure meta-heuristics, the genetic algorithm (GA) and the non-dominated sorting GA (NSGA-II) are the most-used single- and multi-objective algorithms, the aspects of sustainability are mostly addressed in connection with product distribution and routing of vehicles as pivotal operations in supply chain management, and last but not least, the economic-environmental category of sustainability has been further noticed by the scholars. Finally, a detailed discussion of findings and recommendations for future research are provided.

Recent substantial developments of consumer-to-consumer social commerce platforms (C2C-SCPs) emboldened consumers/users to be involved as sellers. Considering C2C social networks that privilege local reach, this paper aim to explore how the practice-based view informs non-professional sellers’ involvement. Underpinned by data from 29 semi-structured interviews with non-professional sellers on Kaskus, one of the largest local Indonesian C2C-SCPs, the study reveals the emergence of a novel structural practice that we call casual selling. The findings show that casual selling allows non-professional sellers’ involvement in C2C-SCPs through three broad categories of practices: priming oneself, producing commercial operations and valuing others. Within these three categories, non-professional sellers are found to generate both personal and collective involvement along nine situated market practices. This paper adds to previous research by introducing the practice-based view to social commerce literature. In doing so, it deals with the under-investigated seller’s perspective and activities that prevail in C2C-SCPs. In C2C-SCPs, casual selling constitutes a distinct mode of involvement in social commerce in which established professional selling standards are suspended. As a structural practice, it entices non-professional sellers to consider a wider variety of situations in which they are in dialogue with other individuals (buyers and sellers) to shape s-commerce potential. In doing so, C2C-SCP users draw on a dynamic intertwining between digital technology and the socio-cultural environment surrounding s-commerce.

The adoption of electric vehicles (EVs) in populated cities is increasing in response to reducing the environmental impact of transportation; however, it also brings new problems to be solved that require innovative solutions such as the optimal use of charged vehicles, the location of charging stations, and managing transportation disruptions in a dynamic environment. This study addresses the problem of recovering a pre-established schedule of an EV when an unexpected disruption occurs. The innovative idea for this problem is reconfiguring the road network by skipping one or more customers while locating alternative points for the temporary storage of consignments initially scheduled to be picked up from (or delivered to) skipped destinations. It is allowed to assign lockers to a neighborhood entailing a set of nodes. This paper designs an integrated form of EV routing problem that simultaneously determines the optimal velocity in each assigned route and the battery recharging policy under a partial charging scheme. The paper also proposes an efficient algorithm based on the Crowd- Learning Particle Swarm Optimization (CLPSO) to solve the large-scale problem. The proposed algorithm surpassed a set of widely used algorithms in the literature using a numerical case study. Computational experiments, based on data from a freight company, demonstrate the effectiveness of the model and CLPSO algorithm. The test results confirm that the developed approach can be a useful reference in practice to provide a robust operation of EVs in metropolitans and populated cities. The results also show that applying all of the proposed recovery actions can significantly reduce the cost of the disruption

This paper aims to investigate the impact of corporate governance practices on cost efficiency and financial stability for a sample of Islamic and conventional banks. In the analysis, the author uses a set of corporate governance variables that include, the board size, board independence, director gender, board meetings, board attendance, board committees, chair independence and CEO characteristics.The author uses corporate governance data of Islamic banks that is unique in this field. In the analysis, the author also uses stochastic frontier analysis and panel vector autoregression models to quantify long-run and short-run statistical relationships between the operational efficiency of Islamic Banks and corporate governance practices.According to the results, Islamic and conventional banks exhibit important differences in the effects of corporate governance practices on cost efficiency and financial stability. Results show that with a blind general adoption of corporate governance practices, Islamic banks may suffer a loss in their value since the adoption of the third layer of binding practices, over and above the already existing ones, imposed by the Sharia Board and the Board of Directors, may lead to cumbersome business operations. This conclusion is of importance to Islamic Banks since they struggle to survive in a very competitive international environment.The author believes that the results may be of a certain value to regulators, policymakers and managers of Islamic banks. Based on the results, the author postulate that Islamic banks should select carefully international corporate governance practices.Islamic banks should not adopt additional third layer of binding practices as that would result lower performance and instability that would be damaging for the economyThis study employs a unique sample of Islamic banks that includes corporate governance data hand collected. Our findings of the corporate governance impact on Islamic banks performance and stability are therefore unique in the literature.

We model and solve a production plannign problem over a discrete-time horizon of a biorefinery that treats different types of biomass and transform them either into bioenergy or biofuel. Both biomass and biofuel can be stored. Storage of biofuel serves to match the supply with the demand of both bioenergy and biofuel. Deterioration of biomass, which was rarely studied in the bioenergy production literature, is modeled and its impact on storage decisions is analyzed. The proposed model has two main characteristics: (i) controlling inventory of the perishable biomass while considering different ages for the stored biomass and (ii) biomass can be transformed into either bioenergy or biofuel, which in turn can be stored and then transformed into bioenergy. The applicability of the developed model is shown through several numerical experiments. The results show that first, perishability can lead to profit losses that cannot be neglected. Second, there is a threshold value on the perishability rate above which perishability does not have any longer impact on the profit. Third, storage and transformation of biofuel results in considerable increase in profit and smoother production at the facility even when there is a high fluctuation in price and demand. Fourth, when the decision maker imposes a maximum age on biomass to enhance quality and reduce health risks, the model provides guidelines on how to make this decision with the lowest impact.

This paper deals with the multi-model assembly line balancing problem (MuMALBP) in a reconfigurable environment. The considered line is composed of a fixed number of workstations and can produce different products in batches. Each product requires an appropriate line configuration. Thus, when the product changes, the line has to be reconfigured to satisfy new requirements related to task precedence and cycle time constraints. Reconfiguring the line consists in reassigning certain tasks between the existing workstations. The objective of this paper is to design a line configuration for each product while minimizing the maximum number of task reassignments whatever the sequence of product arrival. To solve this NP-hard problem, a mixed-integer linear program (MILP) is first formulated. Subsequently, a constructive heuristic and a MILPbased heuristic, named Halt-and-Fix, are developed to solve large-size problem instances. All the approaches are tested and approved on a dataset derived from the well-known instances of the assembly line balancing literature. The numerical results show that the Halt-and-Fix heuristic provides a better trade-off between solution quality and CPU time, compared to the constructive heuristic and the MILP formulation

The conceptualization of the Base of Pyramid (BOP) proposes that low-income markets can lead to profitable opportunities for businesses. The purpose of this study is to identify key success factors of a BOP business strategy based on a case study of the discount retailer, Dollar General, in the USA. The research design used in this research is an in-depth case study of Dollar General in the USA. Qualitative methods are applied in both the primary and secondary data collection and during the follow-on data analysis of Dollar General.
Dollar General’s strategic profile is achieved through the combination of the following four actions which are tailored to compete effectively at the BOP in the USA: creating the neighborhood discounter, raising aspirational appeal, reducing service and eliminating internationalization. The case is specific to Dollar General in a US cultural context.
The case of Dollar General demonstrates how a discounter retailer should not only follow a low-cost strategy to compete at the BOP. Its ability to craft a distinctive strategy is coherent with meeting the logistical, rational and emotional needs of the low-income consumer in the USA.
Many businesses have neglected rural areas of the USA as being unprofitable. The ability for businesses such as Dollar General to serve the BOP segment can foster the socio-economic well-being of communities.
The overwhelming body of the BOP literature is based on emerging markets. To the best of the authors’ knowledge, this is one of the few studies to investigate BOP business strategy in the USA.

Using a novel dataset, this paper explores the link between cross-border flows of illicit money and anti-money laundering (AML) regulatory and judicial system regimes. To this extent, we explore the information contained in thousands of suspicious activity reports filed by US banks and recently disseminated within the FinCEN files investigation. For a sample of 106 jurisdictions, we relate money laundering (ML) flows as well as the central role of each country’s banks within the international ML network to several variables capturing the AML regulatory stance and ML enforcement. The results point to the crucial role played by judicial system performance variables in explaining the layering phase patterns observed in the underlying data.

The need for a study of project portfolio optimization in pharmaceutical R&D has become all the more urgent with the outbreak of COVID-19. This study examines a new model for optimizing R&D project portfolios under a decentralized decision-making structure in a pharmaceutical holding company. Specifically, two levels of decision makers hierarchically decide on budget allocation and project portfolio selection-scheduling to maximize their profit, and we formulate the problem as a bi-level multi-follower mixed-integer optimization model. At the upper level, the investment company has complete knowledge of the subsidiaries’ response, acts first, and decides on the best budget allocation. At the lower level, each subsidiary responds to the allocated budget and decides on its portfolio scheduling. Since the lower level represents several mixed-integer programming problems, solving the resulting bi-level model is challenging. Therefore, we propose an efficient hybrid solution approach based on parametric optimization and convert the bi-level model into a single-level mixed-integer model. To validate it, we solve a case and discuss the optimal strategy of each actor. The experimental results show that the planned project portfolio for each subsidiary of the holding company is drastically affected by the allocated budget and its decisions.

The field of paradox studies keeps struggling to put the notion of paradox into the very centre of organizational life and managerial decision-making, with mixed success. We argue that this research ambition can be realized much more effectively by anchoring the field in three interrelated conceptual approaches which build on paradox as the paradigmatic point of departure. These approaches include Spencer Brown’s form calculus, Niklas Luhmann’s systems and organization theory, and the traditional Indian logical construct of tetralemma. In the proposed argument, paradox constitutes the very identity of organizations as (re-entries of) distinctions drawn in the environment; it is actualized in every act of organizational decision communication, as well as in the process of the continual vanishing and renewal of such acts. In this conception of organizational life, the key challenge is to debunk false distinctions by using tetralemmatization strategies that entail a radical questioning of the problematic observational perspectives.

This research examines the impact of contingent self-esteem on compulsive usage of social media application WeChat in China. The authors attempt to identify the channels based on selfverification and self-determination theory and propose that fear of negative evaluation (FNE) and fear of missing out (FoMO) transfer the impact of contingent self-esteem (CSE) to compulsive WeChat usage (CWU). Additionally, these relationships were tested with frustration about unavailability (FaU) as a moderator in the framework to explain the phenomenon. By employing a convenience method, 396 samples of Chinese students were analyzed. The analyses indicate that CSE contributes to CWU directly and indirectly through FNE and FoMO. Furthermore, FNE mediates the link between CSE and FoMO, ultimately transferring the effect of CSE to CWU in series. These results can enhance our knowledge of how CSE affects CWU, a growing problem among young people today. Our results may guide psychologists to prepare a counselling programme for compulsive social media users and help them overcome social interaction fears in the real world.

This study aims to investigate the moderating role of low and high failure severity levels on recovery satisfaction and on behavioral intentions through recovery satisfaction. This research adopted justice theory and regulatory focus theory to provide further explanations on the inconsistencies in the extant literature regarding service failure and responses to service recovery. This study applied a scenario-based experimental design of two (perceived justice: low vs hig h) by two (failure severity: low vs high) between-subjects factorial design. Data was collected from 237 mobile phone users recruited via convenience sampling. This study examined the hypothesized relations using Hayes (2018) PROCESS macro version 4.0. Perceived justice had a higher positive effect on recovery satisfaction at a high failure severity level. The direct effect of perceived justice on behavioral intentions was significant and positive only at a high level of failure severity, whereas the indirect effect of perceived justice on consumers’ positive behavior through recovery satisfaction was more positive at a high level of failure severity. Justice theory and regulatory focus theory can be used to explain how a well-implemented  recovery effort can offset losses that are caused by a highly severe service failure leading to satisfaction and positive responses. However, as this study was conducted within a telecommunication service context, this research needs to be replicated in other areas, including the use of other data collection methods and measurement of consumers’ regulatory focus orientation. The findings of this study provide managers with valuable insights into the allocation of service providers’ resources for recovery actions according to consumers’ perceived severity levels to regain consumer satisfaction and continued positive behavioral intentions. Past research on the effect of failure severity levels on recovery satisfaction and consumers’ positive behavioral intentions is scant, and those studies that examined severity levels have shown conflicting results. This study attempted to advance the research by examining the relationship between perceived justice, recovery satisfaction and behavioral intentions at low and high failure severity levels using justice theory and regulatory focus theory. None of the theories have been examined concurrently in the service failure and recovery framework.

This paper examines the optimal channel structure of a green supply chain consisting of one manufacturer and one retailer. The manufacturer, who is the Stackelberg leader, is responsible for green technology costs. Consumers prefer green products and therefore are green aware. We study four channel structures: a manufacturer’s dual-channel supply chain, a retailer’s dual-channel supply chain, a manufacturer-online and retailer-offline (hybrid I) structure, and a manufacturer-offline and retailer-online (hybrid II) structure. For each structure, we analytically investigate the impact of consumers’ green awareness and proportion of online and offline consumers on the level of green technology, profits, and retail prices. We also examine the effect on the optimal solutions of the manufacturer and retailer when they share the green cost. The results show that the manufacturer’s dual-channel supply chain performs the best in improving the greenness of products and its own profits. Concerning hybrid dualchannel supply chains, the manufacturer will always choose the channel with the majority of consumers to directly sell products through. The retailer, in most cases, also prefers to operate two channels simultaneously. In addition, regardless of the type of channel structure involved, consumers’ green awareness encourages the manufacturer to improve the greenness of its products; however, the proportion of online consumers has a positive effect on the greenness of products in the retailer-offline and manufacturer-online cases but a negative effect in the retailer-online and manufacturer-offline cases

Carbon emission control and maintaining economic growth drive firms and governments to strike a balance between these two aspects via environmental policies. Inspired by diverse carbon permit trading practices, we study the impact of two variant cap-and-trade schemes on supply chain performance and emission reduction. Focusing on a realistic supply chain supernetwork, we examine the operational decisions and emission mitigations of the system under the carbon caps-pooling and caps-nonpooling schemes which reflect two typical modes of carbon quota in practice.We exploit game theoretical models to characterize the strategic interactions of supernetwork node firms, and then transform them into equivalent variational inequality problems to derive the associated equilibria in different scenarios.We find that the carbon caps-pooling scheme yields a win–win outcome in terms of the environmental and economic performance and the carbon permit sale price affects the decreasing rate of carbon intensity more effectively than the purchasing price. Moreover, the caps-pooling scheme further restrains firms’ opportunistic behaviors of lowering production and selling surplus carbon permits at a high price. Notably, comparing the two carbon schemes implies that under the cap-and-trade policy governments should stimulate firms adopt the caps-pooling scheme with emission permits trading, and accordingly firms have more flexible control over carbon permits. We further conduct computational analysis to validate and illustrate the results, which indicates the robust effect of caps-pooling scheme on the supply chain supernetwork under distinct market structures.

The global pandemic of COVID-19 has underlined the need for more coordinated responses to emergent pathogens. These responses need to balance epidemic control in ways that concomitantly minimize hospitalizations and economic damages. We develop a hybrid economic-epidemiological modeling framework that allows us to examine the interaction between economic and health impacts over the first period of pathogen emergence when lockdown, testing, and isolation are the only means of containing the epidemic. This operational mathematical setting allows us to determine the optimal policy interventions under a variety of scenarios that might prevail in the first period of a large-scale epidemic outbreak. Combining testing with isolation emerges as a more effective policy than lockdowns, substantially reducing deaths and the number of infected hosts, at lower economic cost. If a lockdown is put in place early in the course of the epidemic, it always dominates the “laissez-faire” policy of doing nothing.

We solve a bimodal optimal control problem with a non-concavity and uncertainty through a Poisson process underlying the transition from a mode to another. We use a dynamic programming approach and are able to uncover the global optimal dynamics (including optimal non-monotonic paths) under a few linear-quadratic assumptions, which do not get rid of the non-concavity of the problem. This is in contrast to the related literature on pollution control under irreversibility which usually explores local dynamics along monotonic solution paths to first-order Pontryagin conditions.

In the context of tourism, the current study differentiates social media influencers (SMIs) as local SMIs and foreign SMIs. The current study argues that foreign SMIs help to create a positive (or sometimes negative) image of another destination country abroad that they have visited or lived in, unlike local SMIs who mostly help promote touristic places of their own country in their own country. While prior studies have investigated the influence of social media influencers (SMIs) in travel decisions in general, it is not clear whether foreign SMIs can help shape another destination country’s tourism image (DCTI) abroad. The current study fills this gap by investigating French SMIs’ influence in shaping South Korea’s destination country image in France. The leading French SMIs who actively create and share content about South Korea on their social media channels, such as YouTube, Instagram, Tik Tok, and Twitch, are identified and analyzed. Applying the netnographic method to four SMIs’ communities of followers shows that French SMIs directly influence the DCTI of South Korea in France by influencing their cognitive, affective, and conative dimensions, although the effect on each varied. Moreover, the affective route had the highest impact, followed by the cognitive and conative route.

We investigate how to secure reliable access to personal protective equipment (PPE) in pandemics, which are characterized by random occurrences and durations, at the lowest expected cost. The policymaker’s strategy is based on a mix of (1) holding ready-to-use strategic stockpile that is acquired at regular price but incurs a holding cost, (2) building partnership with PPE manufacturers to relocate offshore production locally, which guarantees some local supply but requires offering subsidies, and (3) buying PPE from the spot market, which is characterized by long supply lead times and high prices.
We model the problem as a Stackelberg game between a policymaker (leader) and a manufacturer (follower). The policymaker decides the PPE stockpile, the subsidy offered to the local manufacturer, and the quantity to buy from the spot market. The manufacturer determines whether to move production onshore. We determine the optimal strategy for each player and study the effect of spot market conditions and pandemic characteristics.
Analytical results show that attracting local manufacturers is less costly for the government when the variability of pandemic duration increases. While it is sub-optimal to rely only on the strategic stockpile, holding some stockpile may be necessary even when the PPE can be obtained from the spot market as soon as the pandemic starts. Results reveal policymaker’s preference for subsidizing onshore production in the following cases: products with low spot prices (counter-intuitively), spot market with long supply lead time, less frequent pandemics, and shorter pandemics.

Tax amnesty (TA) schemes are typical in developing countries. Governments’ claims and suppositions are continually heightened; however, this may differ in actuality. This study aims to present an overview of the effectiveness of TA schemes and the problems they raise in implementing anti-money laundering regulations. This study used a qualitative research design. Content analysis was used to analyse research articles, reports, legal documents and news articles. Every amnesty offered in Pakistan from 1956 to 2018 failed to meet government expectations. Instead, the continuity resulted in an irrepressible black economy. The black economy’s uncontrollability undermines tax collection and hinders a robust anti-money laundering regime. Significantly, tax holidays with discrepant legislation strengthen evaders, plunderers and launderers. These policies severely impede the implementation of anti-money laundering policies in the financial institutions of Pakistan. Additionally, Pakistan’s geopolitical location, circumstance and war against terror cannot afford any policy that provides monetary relaxation to offenders. There is no concrete evidence to support long-term economic progress through the implementation of amnesty schemes as a revenue collection policy. This study evaluates previous studies and findings to understand the effect of tax amnesties on the financial industry of Pakistan. The findings have practical implications for tax collection authorities, policymakers and international financial bodies. Previous studies have discussed the advantages and disadvantages of Pakistan’s regular tax amnesties. However, this study discusses the implementation of TA schemes concerning anti-money laundering regulations and customer due diligence by financial institutes and provides suggestions to minimize its negative implications.

This paper aims to develop a quality evaluation model for artificial intelligence (AI)-based products/services that is applicable to startups utilizing AI technology. Although AI-based service has risen dramatically and replaced many service offerings, in reality, startups are rarely to develop and evaluate AI services. The features of AI service are fundamentally different from the properties of existing services and have a great influence on the customer’s service selection. This paper reviews startups’ development process, existing quality evaluation models and characteristics of services utilizing AI technology and develops a quality evaluation model for AI-based services. A detailed analysis of a survey (application of the model) on customer satisfaction for AI speakers is provided. This paper provides seven key features and 24 evaluation items for evaluating AI-based services. This paper contributes to the growing need for methodologies that reflect the new era of AI-based products/services in quality evaluation research.

As a severe challenge to governments, air pollution threatens many lives annually. This paper develops an evolutionary game theory model for supply chains (SCs) to encourage firms to reduce carbon emissions. A government dictates three carbon policies: carbon cap, carbon tax, and cap and trade. We construct six scenarios according to the carbon regulations and SC functions (i.e., centralized versus decentralized ones). First, the profit function of SCs that are the input of the game matrix is formulated, and optimal final prices and quantities of products are obtained. Then, an evolutionary game-theoretic model is formulated to analyze the behavior of populations by obtaining the evolutionary stable strategy under each scenario. In addition, three models of government intervention are presented, considering the cost associated with environmental pollution and government net revenue. Finally, a case study of motorcycle production dissects the results. The findings demonstrate that cap and trade can be introduced as an incentive policy since it encourages SCs to adopt green strategies and improves their profit. A carbon tax policy also succeeds in pressuring SCs to apply green strategies. However, a carbon cap policy fails in forcing SCs to adopt green strategies. Finally, it is concluded that decentralized supply chains (DSCs) handle high tax rates better than centralized supply chains (CSCs).

  • Xia, Fan (2023) Common Institutional Owners and Mergers and Acquisitions Outcomes. Review of Quantitative Finance and Accounting, volume 60, issue 4, pp. 1429–1449

Institutional owners frequently invest in a diversified portfolio of firms to avoid firm-specific risks. I investigate the particular scenario in which the institutional owners have shares in both the acquiring and the acquired target firms of an M&A deal. Using a quasi-experimental approach, I find that the acquirer pays less premium and performs better after the M&A effectiveness when the ratio between the value owned by common institutional shareholders in the acquirer and the value held by the same shareholders in the target firm is higher. The value paid is higher, and the performance worsens when this ratio is lower. The results suggest the common institutional owners can obtain benefits from promoting and implementing such M&A deals as a secondary compensation for their lack of control, usually at the expense of the controlling shareholders.



  • Agata Mirowska, Jbid Arsenyan (2023) Sweet escape: The role of empathy in social media engagement with human versus virtual influencers. International Journal of Human-Computer Studies, Volume 174, June 2023, 103008

Virtual influencers engage in emotional sharing to gain and keep followers. However, given that many people use social media for diversion purposes, this emotional sharing may hinder users’ ability to escape from everyday emotional experiences, particularly for highly empathetic individuals. Using a between subjects, randomised experimental design, we explore how empathy affects reactions to virtual vs. human influencers, showing that those highest on empathy are more likely to follow a virtual influencer, and rate her as more socially attractive, than a comparable human influencer; these results disappear when the influencers’ true nature is unknown to participants. We postulate that these results represent an “escapism effect”, where the virtual influencer is expected to provide greater diversionary benefits from everyday human emotional experiences and require fewer cognitive resources in the form of emotional sense making. We present practical implications and future research opportunities arising from this effect.

We develop a theoretical framework and propose a relevant empirical analysis of the soybean complex prices’ cointegration relationships in a high-frequency setting. We allow for heterogeneous expectations among traders on the multi-asset price dynamics and characterize the resulting market behaviour. We demonstrate that the asset prices’ autoregressive matrix rank and the speed of reversion towards the long-term equilibrium are related to the market realized and potential liquidity, unlike the cointegrating vector. Our empirical application to the soybean complex, where we control for volatility, supports our theoretical results when the price idleness of the different assets is properly accounted for. Our analysis further suggests that the presence of cointegration among assets is related to the time of day and the contract maturities traded at a given time

  • Xiaolong Guo, Xiansen Li, Junsong Bian, Chenchen Yang (2023)Deposit or reward: Express packaging recycling for online retailing platforms. Omega, Volume 117, 2023, 102828

To motivate consumers’ participation in recycling, we study two recycling policies for express packaging on an online retailing platform equipped with self-run logistics to collect express packaging from con- sumers. First, under the Deposit-Refund Policy (DRP), when consumers purchase from the platform, they pay a deposit for the express packaging, but the deposit will be refunded if they return the packaging to the platform. The other is the Recycling Reward Policy (RRP), under which the platform provides rewards when consumers return express packaging. The platform decides whether to recycle the express pack- aging and chooses the optimal recycling policy if recycling is economically feasible. To investigate, we first set up an optimization model to analyze these two recycling policies. Using the No Recycling Policy (NRP) as the benchmark, we then derive managerial insights through comparative analysis and numeri- cal studies. Our results indicate that the consumers’ green consciousness plays a critical role in decision making. Specifically, NRP is optimal for the platform when the green consciousness level is low. As the consumers’ green consciousness level increases to a medium range, recycling becomes feasible and RRP is optimal. If the green consciousness level is high, DRP will be the optimal policy. These findings have helpful implications for corresponding decisionmakers (e.g., express industry managers, government de- partments) to cautiously judge whether to recycle express packaging and which recycling policy is best under different circumstances.

  • Junsong Bian, Guoqing Zhang, Guanghui Zhou (2023) The strategic impact of vertical integration on non-deceptive counterfeiting. International Journal of Production Economics, Volume 260, 2023, 108863

Counterfeits have been common in practice despite ongoing criticisms and regulations. This paper analyzes the strategic effect of vertical integration on non-deceptive counterfeiting. We find that integration has a less stringent requirement on the efficiency of the brand product’s quality improvement and can serve as an anti-counterfeiting strategy to help the brand firm deter non-deceptive counterfeits. However, integration may also increase the demand of the non-deceptive counterfeit. Integration always increases the brand product’s quality and demand facing non-deceptive counterfeits. Compared to decentralization, the counterfeiter’s profit is lower under integration when the counterfeit imitation is close and brand product’s quality improvement is highly efficient. Besides, our result indicates that with non-deceptive products, the brand firm can benefit from integration, which however may also benefit the counterfeiter. Furthermore, vertical integration always enhances consumer and social welfare. Finally, we also extend the model to other cases including sequential quantity competition and two types of product features.

This study aims to investigate the impact of managerial power distance on the corporate sustainability performance of Chinese firms and to explore the regulatory role of corporate digitalization in the Chinese capital market. The study collects data from 2,632 A-share Chinese non-financial firms listed on Shanghai and Shenzhen stock exchanges during the period from 2010 to 2020. The authors apply different panel data regression techniques (fixed effects, GMM-System) to investigate the impact of managerial power distance on corporate sustainability performance and to explore the regulatory role of corporate digitalization in the Chinese capital market. The results of the study show a positive relationship between high managerial power distance and the sustainability performance of Chinese non-financial firms. This positive relationship is particularly pronounced in Chinese state-owned enterprises (SOEs). The results also show that corporate digitalization increases the sustainability performance of Chinese firms. Further, corporate digitalization weakens the positive relationship between high-power distance and the sustainability performance of Chinese firms. These results are robust to alternate sustainability performance measures and various regression techniques. To the best of the authors’ knowledge, this is the first study that investigates the regulating impact of corporate digitalization on the relationship between managerial power distance and corporate sustainability performance in China.

The established literature demonstrates the critical role of the policy mix in the formulation and implementation of government policies for industrial upgrading. However, existing studies mainly examine the policy mix from either a horizontal or a vertical coordination perspective; very few examine both dimensions. To gain further insights, the current study involves an analysis of how China’s central government manages horizontal and vertical coordination to pursue upgrading in manufacturing industries on the basis of an ambidextrous policy mix perspective and a thorough examination of both the external attributes (i.e., policy level) and content (i.e., policy instruments and themes) of policy documents. This analysis reveals several viable policy implications in relation to China’s manufacturing transformation. In particular, it finds that China’s policy mix for achieving manufacturing upgrading is highly coordinated on both horizontal and vertical dimensions. Governments at all levels apply the same set of policy instruments; environmental instruments are the most frequently used, followed by supply- and demand-side instruments. The core policy topics within the manufacturing upgrading structure include innovation, industrial transformation, industrial agglomeration, demonstration projects and service-oriented manufacturing. Therefore, this study establishes recommendations for future policies, which should focus on reinforcing guidance regarding national policies, encouraging local governments to apply innovative policy tools and increasing the use of  demand-side policy instruments

Even though scholars have widely asserted that ambidextrous organizations need ambidextrous managers, we still know relatively little about the emergence of ambidextrous behaviours among top management team (TMT) members. The purpose of this study is to gain a deeper understanding about how TMT networks and middle management involvement in decision-making collectively shape the ability of TMT members to deal successfully with the exploration–exploitation paradox. Through in-depth interviews and a multilevel analysis of internal networks of 123 TMT members in 20 public hospitals, results suggest that leaders’ centrality and the density of TMT networks shape the ability of TMT members to behave ambidextrously. The framework of this paper also incorporates the role of middle management, critical in linking the strategic apex and the operating core, and thereby supporting TMT members’ ambidextrous behaviour. Various theoretical and practical implications are discussed.

Many stockpiled personnel protective equipment (PPE) were of no use during COVID-19 because they have expired. The need for rethinking past approaches of building PPE stockpiles without planning for their timely rotation has become clear. We develop a game-theoretic pandemic preparedness model for single and multiple PPE products for a budget-constrained governmental organization (GO) supplied by a manufacturer. The GO maximizes preparedness, measured by the service rate of PPE, whereas the manufacturer maximizes profit. The manufacturer supplies the PPE stockpile in the first year. Thereafter, the manufacturer buys back a quantity of older PPE from the GO annually and sells the GO the same quantity of new PPE. The manufacturer sells older PPE in the market place. We find that this approach induces the manufacturer to rotate inventory in the stockpile. Joint determination of the stockpile size and its rotation results in no waste from expired PPE and is better than separately determining the stockpile size and then determining how to rotate it. Using insights from the single PPE model, we examine the optimal budget allocation among multiple PPE products. We also consider the effect of spot market prices of PPE during a pandemic on the optimal stockpile sizes. We find that spot market prices of PPE can have a significant effect on the optimal stockpile sizes. We examine the performance of the proposed approach in a manufacturers-distributor-GO supply chain and with an option for the GO to invest in the manufacturer’s volume flexibility and show its effectiveness.

Disruptions often occur in liner shipping networks, and they are costly. When they occur, freight companies evaluate their effects on freightage in the pipeline and take the appropriate recovery actions by balancing customer service levels and increases in fuel consumption while accounting for environ- mental impact (greenhouse gas (GHG) emissions). The paper, therefore, develops an integrated mixed- integer programming problem (MIPP) that jointly minimizes the total voyage and transshipment costs and penalty charges for emitting GHG excess amounts beyond what is allowed. It does so by recovering a pre-established schedule of disrupted containerships. The solution to the MIPP suggests how to reconfigure the liner shipping network when skipping one or more call ports and determines the optimal velocity on assigned routes. The paper also develops and proposes a new and efficient algorithm based on the Crowd-Learning Particle Swarm Optimization (CLPSO) to solve this large-scale problem and shows the CLPSO to be superior to the potential ones in the literature. Computational experiments, based on data from a maritime shipping company, demonstrate the effectiveness of both the MIPP and CLPSO using several comparative metrics with suitable assumptions. The numerical results show that the developed MIPP has a potential application in practice.

This paper explores the link between a country’s position in the aerospace global value chain (GVC) and the strength of its innovation system. Countries’ participation to different stages of the GVC is proxied using export data at a narrow product level, while innovation system indicators are built from US patents. The analysis covers the 2007–2018 period for 38 countries. Our results highlight a relationship between the strength of the innovation system and a country’s participation and specialization in different stages of the aerospace GVC: varied and pervasive (quality) rather than more intensive (quantity) innovation systems are associated with a stronger presence in higher value-added stages of the value chain. These results highlight the importance of improving an innovation system targeting the development of a differentiated knowledge base and fostering the integration of different actors to sustain the aerospace industry and facilitate upgrading within the value chain.

The purpose of this study is to investigate the impact of policy uncertainty on firm performance and to examine how the different cultural societies deal with the policy-induced uncertainty. The authors use data of European non-financial firms to extend the growing literature on policy uncertainty, firm performance and national culture. The authors consider financial as well as market proxies to measure firm performance and use Hofstede’s cultural dimensions as a proxy for national culture. The authors apply the generalized method of moments (GMM-system) regression technique on a dataset of 702 non-financial European firms, listed during the period 2002–2018.
The authors find overwhelming evidence that policy uncertainty reduces the performance of the European firms; however, cultural differences among different European countries moderate the impact of policy uncertainty on the financial as well as the market performance of the firms. The results of this study show that European cultures with high power distance, individualism, masculinity and indulgence efficiently deal with the economic policy uncertainty. While the European societies with high uncertainty avoidance fail to cope with policy-induced uncertainty. The results are robust to different regression models, alternate proxies of firm performance and endogeneity issues.
The authors argue that policy uncertainty increases information asymmetry and decreases firm performance, therefore, the policymakers shall be considerate of the consequences of the policy-induced uncertainty in the society and business arena that would not only adversely affect the firms but also the economy.
To the best of the authors’ knowledge, this is the first study that investigates the role of national culture on the relationship between policy uncertainty and firm performance in the European context.

The North American Journal of Economics and Finance, Volume 67, 2023, 101946

This paper provides new evidence on herding behavior. Using daily frequency data for 336 US listed firms over a five-year period, we investigate three important elements of financial herding behavior. First, trading volume, representing market interest, as a significant variable in capital markets apart from stock prices. Second, herding dynamics since herding formation is a dynamic process. Third, the reaction of possible financial herding to exogenous events-threats, as we use the pandemic event in order to investigate a market under stress. Even though the benchmark herding model used does not provide evidence of herding behavior, our results verify the significance of the above herding elements. We also find that trading volume and positive changes in trading volume result in increased cross-sectional absolute deviation (CSAD). Most importantly, we find that herding behavior is evident during the COVID-19 pandemic confirming that investors tend to herd during major crisis periods.

We study the effect of board reforms on firms’ research and development (R&D) investments utilizing a sample of 41 countries. Using a difference-in-differences analysis, we find that firms invest more in R&D following corporate governance reforms. Of these, two legal reforms — having an independent audit committee and board independence — have a greater impact on R&D investment. Additionally, we show that board reforms have a more pronounced effect on R&D investment in hi-tech industries and the health sector.

Digital-free tourism is an emerging trend that limits tourists’ access to information and communication technologies during vacations. However, how to motivate tourists to engage in digital-free tourism is not yet understood. Anchoring on Construal Level Theory and educational intervention, this study examines the effects of message concreteness and intervention type on tourists’ intention to take digital-free tourism. Experimental data from 249 respondents showed that when factual intervention was provided, tourists were more likely to engage in digital-free tourism when they received abstract messages instead of concrete messages. Our findings can contribute to the design of promotional messages for digital-free tourism.

Firms develop and deploy selling capability to create and sustain a competitive advantage. Previous studies have focused predominantly on static, input-based selling capability, paying little attention to dynamic, efficiency-focused selling capability. This treatise econceptualizes selling capability from a dynamic and efficiency (input–output) perspective and investigates the effect of selling capability on firm value with the contingent role of internal [i.e. relative strategic emphasis (SE)] and external (i.e. market volatility and technological volatility) factors. Using data from 341 US-based manufacturing and service firms over the period 2014–2020 and an endogeneity-robust dynamic estimation technique, the authors find that selling capability positively affects firm value, and firms with a relative SE on value appropriation (i.e. advertising) as opposed to value creation (i.e. R&D) reap more rewards from selling capability. That is, relative SE positively moderates the nexus between selling capability and firm value. Furthermore, the results demonstrate that the interactive effect of selling capability and relative SE is weaker when an industry experiences higher market volatility but stronger when technological volatility is higher. Overall, this study demonstrates that a firm’s selling capability should be managed dynamically in light of its (internal) relative SE and (external) environmental conditions. The results are robust to several additional sensitivity analyses

This study investigates how sharing ventures address the paradox of doing good versus doing harm in their strategic decision-making. The doing good versus doing harm paradox refers to the difficulty of sharing ventures to balance the aim to benefit society and the environment while minimizing potential adverse effects. Understanding and addressing this paradox is crucial for promoting sustainable and responsible decision-making. Our thematic content analysis of 38 in-depth interviews with founders and senior managers of sharing ventures in four European countries finds that these ventures align along three distinct value focus types in their decision-making and use five mechanisms to conceal paradoxes related to balancing social/environmental and economic contradictions. By surfacing the importance of sharing ventures’ value focus and resultant mechanisms to deparadoxify, our findings provide insights into organisational paradox and the sharing economy, specifically the purposeful concealment of paradox as a counterintuitive choice for remaining actionable in decision contexts.

Virtual agent research has evolved into a substantial body of work, albeit one with a fragmented structure and overlapping, and at times inconsistent, definitions and results. The current paper presents a computational literature review of 1865 academic journal publications and conference proceedings from 1995 to 2022 using Latent Dirichlet Allocation to understand the publication trends in the field, its intellectual structure, and how topics within virtual agent research have evolved and relate to each other. Our results point to a model of 16 topics as best representing the current state of the research landscape. We present descriptions of these topics, as well as topic dynamics and networks, in order to provide a clear picture of the current state of the field. We then organise these topics into a Human-Virtual Agent Coexistence Framework, identifying current trends and opportunities for future research.

Social media message strategy is critical in determining how customers will engage with B2B firms on social media platforms. The present study examined the role of message source (i.e., firm-generated vs. employee-generated) and message content (i.e., emojis and objective information) in determining social media engagement. Four experiments were conducted to test the proposed relationships. The study findings revealed that employee-generated content leads to higher social media engagement (i.e., intentions and behaviors) than firm-generated content. Content-based trust and engagement-based trust were found to be the underlying mechanisms by which message source impacts social media engagement. Furthermore, we observed that, for an employee-generated message, including emojis has a greater impact on customer engagement than when they are included in a firm-generated message. Finally, no evidence was found concerning the effectiveness of incorporating objective information in social media messages on customer engagement. These findings have marked implications for B2B marketers in developing effective social media message strategies

The introduction of consumer-initiated models with small group size has increased the popularity of group buying. With lower size requirements for forming buying groups, more impulsive buying is facilitated while more postpurchase regret is spawned. Consumer postpurchase regret not only poses challenges to the coordination of group buying but may also eventually lead to merchant losses. Therefore, understanding the factors that may affect consumer postpurchase regret in group-buying contexts is crucial. Drawing on observational learning theory and expectancy disconfirmation theory, the present study focuses on how the response speeds of group-buying campaign coparticipants intertwined with publicly available information of group-buying deals (i.e., the deal popularity and expected savings) to affect campaign initiators’ postpurchase regret. Through secondary data analysis and a laboratory experiment, we find that a lower coparticipant response speed is associated with a higher likelihood of the initiator experiencing postpurchase regret. In addition, when deals have a higher level of popularity, this effect is amplified. Our findings demonstrate the potential importance of considering the coparticipant effect to discourage negative consumer behavior in group-buying contexts.

A large volume of global transportation is carried out annually by liner shipping companies and it includes a large portion of global trade. Accordingly, due to the countless number of these voyages, precise planning in this field is vital to prevent severe loss. One of the noticeable issues that occur during the voyage can be natural or human disruption which is interpreted as a “delay” in the liner shipping services. Therefore, there is a need to reschedule the pre-established plan to compensate for the delays and reduce the costs including the penalties and exceeding fuel consumption. In this paper, a novel recovery model is proposed for container ship problems. This mixed-integer programming model with the use of speedup, skip, and swap ports strategies not only attempts to mitigate the dire financial consequence of the disruption but also reduces the carbon footprint. Furthermore, to ensure customer satisfaction, the alternative transshipment decision for the skipped ports cargo is considered in the model. The nonlinear model is linearized through the exact techniques, then solved in CPLEX software. As a result, the primary deterministic model could act as a “wait-and-see” solution to reduce disruption losses by up to 66% using simultaneous recovery strategies of speedup, skip and swap. However, a robust optimization approach is proposed owing to the uncertainty in delay time, type, severity, and point of disruption. This approach enables the model to face a wide variety of disruptions (that are predicted under different scenarios each of which is associated with an occurrence probability) and recommends an augmented schedule that guarantees to be feasible, optimal, and resistant. The robust model is applied in a real case from the maritime industry, and the value of robustness is reported. The results demonstrate the superiority of this model compared with others.

The research on Industry 5.0 (i5.0) is relatively new and emerging therefore professionals are still striving to reveal its influence globally. This study investigates the impact of industry 5.0 to comprehend the insights into how it optimizes the sustainable performance (STP) within three core streams, that is, economic, environmental, and social perspectives from the realm of stakeholder theory within the Chinese agricultural industry. The results stated that i5.0 positively affects the STP of Agri-enterprises. The empirical testing additionally affirmed the positive nexus of i5.0 practices toward each dimension of STP such as social, environmental, and economic perspectives based on structural equation modeling. First, it found that i5.0 has a positive correlation with the economic perspective. Second, the findings affirmed the positive linkage between i5.0 and the social perspective. Finally, the study indicated a significant correlation between i5.0 and the environmental perspective. This study provides real-time empirical evidence for the management of Agri-enterprises regarding i5.0 and insights into the embodiment of such capabilities to optimize enterprise STP by incorporating i5.0 model. This study presents several theoretical and managerial enrichments for Agri-enterprises along with future avenues for the researchers to test the i5.0 capabilities toward rest of the sectors across the world.

The present research examines the role of the image of a hand in an online product evaluation. Through eleven studies (i.e., six in the manuscript and five in the Web Appendix), we show that, when a hand image is depicted in an unsupported holding position (i.e., lifting a product), consumers’ confidence in their judgment of the product’s weight is enhanced. This outcome increases product evaluation, purchase intention, and product choice. The hand image effect is mediated by a mental representation of a haptic experience (i.e., haptic imagery). Additionally, we show that an image of a hand in an unsupported holding position increases consumers’ confidence in the product’s weight, while other hand positions or their absence do not have a similar impact. Online retailers can use our findings to employ hand images to influence the evaluations and purchase intentions of products in which weight is a salient haptic attribute.

In this paper, we consider common-pool non-renewable resource industries and study the socially optimal industry size. Our analysis is conducted in terms of an infinite-horizon differential game (with either open-loop or feedback strategies). We derive two main results. First, we show that there exists a unique state-independent efficiency-inducing industry size, ranging between 1 and infinity, if and only if the elasticity of the price-cost margin (capturing static market power) and the elasticity of the difference between social and private resource rents (capturing the tragedy of the commons) are the same. Second, allowing for entry/exit, we show that the regulator can set a license fee to be paid by firms to get access to the resource such that the endogenous number of firms in the equilibrium with regulated entry is socially optimal.

We find out-of-sample predictability of commodity futures excess returns using combination forecasts of 28 potential predictors. Such gains in forecast accuracy translate into economically significant improvements in certainty equivalent returns and Sharpe ratios for a mean–variance investor. Commodity return forecasts are closely linked to the real economy. Return predictability is countercyclical, and the combination forecasts of commodity returns have significant predictive power for future economic activity. Two-factor models featuring the market factor and the innovations in each of the combination forecasts explain a substantial proportion of the cross-sectional variation of both commodity and equity returns. The associated positive risk premiums are consistent with  Merton’s (1973) intertemporal capital asset pricing model (ICAPM), given how the combination forecasts predict an increase in future economic activity and a decline in stock market volatility in the time-series. Overall, combination forecasts act as state variables within the ICAPM, thus resurrecting a central role for macroeconomic risk in determining expected returns on commodities.

Product return rates are much higher for online retailers than brick-and-mortar retailers. In this paper, we develop a model for optimizing the retailer’s price, quantity, and terms of the product return policy in the presence of consumer opportunistic behavior (wardrobing). We consider a seasonal product and formulate and solve a newsvendor (e-tailer) model where an in-season price markdown may be used before any remaining inventory is salvaged at the end of the season. We compare a return policy in which refunds for returned products are in cash to one where refunds are in store credit or gift cards (SC/GC). Products sold at the clearance (salvage) price cannot be returned or exchanged. We find that with both cash and SC/GC refunds, consumer product match uncertainty, measured by the probability of the product matching consumers’ expectations, benefits consumers who keep the product more than consumers who return it. Moreover, under realistic conditions, using SC/GC refund increases the profits of the e-tailer and benefits consumers who keep the product by lowering the price. We also find that even when consumers redeem all SC/GC, using SC/GC refunds can still be beneficial to the retailer because SC/GC refunds deter proportionally more wardrobers from buying than consumers from buying. As a result, costly returns are reduced and the e-tailer benefits.

This study aims to examine the individual and interactive effects of the founder’s prior experience and managers’ foreign market knowledge on international opportunity identification by early internationalizing firms (EIFs). We draw on a sample of 332 small and medium-sized EIFs from a South Asian country, viz. from the Bangladeshi apparel industry. This study adopts a survey-based quantitative research approach. A hierarchical regression modeling technique is used to test the contingency hypotheses. The results demonstrate that founding entrepreneurs’ prior experience and managers’ experiential knowledge are strong predictors of international opportunity identification. While we hypothesized for the joint negative effects of founders’ prior experience and managers’ market knowledge on opportunity identification, the results were non-significant, thus partially supporting the assumptions of agency theory. Our study provides valuable empirical insights into and supports the role of founders’ prior experience and managers’ foreign market knowledge in investigating international opportunity identification.

  • Sandro Montresor & Antonio Vezzani (2023) Digital technologies and eco-innovation. Evidence of the twin transition from Italian firms, Industry and Innovation, Volume 30 issue 7, pp. 766-800

This paper investigates how the twin transition (digital & green) unfolds within firms by relating investments in digital technologies to the propensity of eco-innovating production processes and models. Drawing on a heterogeneous theoretical background, digital technologies can be hypothesised to enable eco-innovation across the board. However, a greater eco-innovation impact is expected from Artificial Intelligence and from bundling digital investments. Using the new Permanent Census of Firms of the Italian National Statistical Office, these hypotheses are tested on a large sample of more than 150,000 firms. Results confirm that the contribution of digital technologies to a firm’s eco-innovation is mainly driven by investments in AI application areas, while investments in other digital technologies work more selectively. Moreover, new eco-innovative production processes and models benefit from bundling investments in different digital technologies, but with differences among firms of different size.

This study explores the professional work of managers in professional service firms (PSFs) by focusing on the relational position of managers as they interface between diverse groups of actors and navigate a multiplicity of accountabilities. Drawing on an ethnographic study of managers in a Brazilian PSF, this study demonstrates through observations, interviews and shadowing how PSF managers address multiple accountabilities in the conduct of professional work. To navigate multiple accountabilities, PSF managers perform several forms of boundary work, which the authors conceptualize as “revamping” and “remolding” operations and “translating” and “transforming” understandings. The form of boundary work performed depends on the configuration of two elements of accountability demands: knowledge orientation and extent of exposure. Although analytically distinct, these elements intertwine, suggesting the need for a dynamic perspective on accountability. The analysis shows that professional work extends beyond fixed or passive views of hierarchical and intrinsic accountability to emphasize that managers exude accountability of an adaptive nature. This study illustrates and theorizes the role of boundary work in PSFs, develops its link to accountability, and identifies its scholarly and practical affordances and limitations for understanding managers’ professional work when navigating multiple accountabilities. The findings reveal perspectives and behaviors of managers embedded in PSFs, illustrating their unstructured and agentic experiences of accountability and boundary work in practice. The insights can be extended to other contexts where managers face multiple accountabilities in conducting professional work.

We examine the effect of bilateral trust on cross-border mergers and acquisitions (M&As). Using a large European M&A sample, we find that bilateral trust facilitates deal announcement and completion. Bidder and target bilateral trusts towards each other are both important for deal announcement, but only bidder trust towards the target firm matters for deal completion. The effect of bilateral trust on deal completion is amplified in more complex transactions and when bidders face severe liability of foreignness. Moreover, bilateral trust between the parties is also associated positively withmerger performance. These results support the importance of bilateral trust as a deal facilitator in negotiation settings characterized by contract incompleteness and liability of foreignness

Big data have the potential to revolutionize the project management, but it is not clear how. Despite the growing interest, there is a paucity of exploratory research to assess the practice and the impact of big data tools and technologies on project management approaches and practices. To address this gap, in this article, we initially embrace the technological–organizational–environmental (TOE) framework as the research basis for the adoption process and conducts in-depth interviews with project managers from French organizations in different sectors. The synthesis of interviews reveals that many organizations are still in the early stage of the adoption process, mainly due to a lack of resources, especially expertise. Besides the factors of the three contexts of TOE, the project-level factors are also found to be critical for the adoption of big data in project management.Most of them adopted big data solutions to support them in the conception, definition, and execution phases of project management. Drawing on the findings, this article also provides guidelines to broaden the understanding of big data applications and their role in project management. Based on these results, we present a model with testable propositions and discuss insights that arise for organizations and project managers regarding how to apply big data tools and technologies to create value and overcome the related challenges

This study examines the moderating role of consumers’ attachment anxiety and attachment avoidance, on the relationship between recovery satisfaction and their behavior after service recovery. This study analyzes the moderating effect of consumers’ attachment styles to explain the differences in their behavior after service recovery efforts, which has not been explored previously. Primary data was collected from hand-phone users, and the effect of consumers’ attachment styles was examined in the context of the telecommunication sector. Findings indicate that consumers high in attachment anxiety were more likely to repurchase but not to engage in positive word-of-mouth after recovery satisfaction. Attachment avoidance did not impact consumers’ behavioral intentions. In addition, the interaction of anxiety and avoidance positively influenced word-of-mouth intentions upon satisfaction with recovery efforts. However, the interaction did not affect repurchase intentions. This study provides insight into how consumer’s attachment style influences their positive behavioral intentions after recovery satisfaction. We present segment-specific relationship marketing strategies that can aid service providers in managing service recoveries and minimizing the adverse effects of service failures on customer retention

The visual and textual elements of packaging significantly impact consumer product evaluations. This study examines how unconventional packaging messages—a textual packaging element—influence impulsive product purchases. We also investigate the mediating role of curiosity and the moderating role of emoji (i.e., a visual packaging element). We conduct five studies to test the proposed hypotheses. The findings reveal that unconventional packaging messages are more effective for impulsive products than for planned purchases. Furthermore, unconventional packaging messages increase both healthy and nonhealthy impulsive product purchases. We find that consumer curiosity explains the enhanced impulsive product purchasing when unconventional packaging messages are used. When unconventional packaging messages are employed for impulsive products, the use of emojis increases customer curiosity. The results extend an understanding of unconventional elements in consumer evaluations of products and inform packaging and marketing strategies regarding how to promote impulsive product purchases in competitive markets.

This paper proposes to adapt the model of pricing decisions developed by Alvarez, Lippi, and Paciello (2011) to the decision process of forecasters. The model features both a fixed cost of announcing a revised forecast and a fixed cost of updating the information set and adapting the forecast accordingly. Basically, the former fixed communication costs determine state dependence, which implies that the forecaster changes its forecast only when it is far enough from the optimal forecast, i.e., beyond a fixed threshold; the latter fixed information costs determine time dependence, which implies that the forecaster updates its information set only every other T periods, where T is optimally chosen.We show that survey data of inflation forecast updates as well as the last known monthly inflation rates can be used to estimate the threshold implied by the theoretical model. This threshold estimate is then crucial to uncover the existence of both types of costs as well as an upper bound of the optimal time between two information observations. French and German data suggest that the maximum optimal time to next observation is six months, while the observation cost is at most twice as large as the communication cost.

British Journal of Management, Volume 34, Issue 4, October 2023, pp. 2036-2056

This study examines new product development (NPD) processes in high-technology new product ventures in the emerging market context. Drawing upon the knowledge-based view and the capability-based view, we propose a model that characterizes relationships between NPD process execution stages and product competitive advantage, and accounts for the moderating effects of NPD integration mechanisms on these relationships. Our model also explains how pricing capabilities can become a liability that undermines how product advantage impacts new product performance. We test this framework within an emerging market context that has been notably absent from the literature. Our data are generated from 187 new product projects and a follow-up of 83 projects, from Chinese high-technology ventures.We identify important theoretical interdependencies within our structural model results. Specifically, marketing–technical integration positively moderates the relationship between product development and testing capability and commercialization capability, while new product implementation capability positively moderates the relationship of commercialization capability and product competitive advantage. Yet, penetration pricing capability negatively moderates the link between product competitive advantage and new product performance.

  • Duhamel, F., Niess, A., & De Geuser, F. (2023). Imagining aesthetic leadership. Leadership, Volume 19 issue 5, pp. 413-430

The study of aesthetic leadership has recently gained importance in the organizational literature, wherein some authors focused on the perception and manipulation of “beautiful” artifacts and others focused on relational processes, “dwelling in the senses” (Ropo et al., 2017). In contrast to those views, we argue that aesthetic leadership highlights the role of imagination, beyond artifacts and sense perceptions. To give due consideration to imagination in aesthetic leadership, we show how Kant and Arendt’s philosophies can be transposed to organizational studies to formulate three roles for imagination in leadership: 1. Achieve representative thinking in leadership processes; 2. Allow leadership to create social commitment to put those representations into action; and 3. Sustain a capacity of projective agency as the capacity of inventing alternative but feasible futures.

This explorative qualitative study of 100 SMEs from 20 industries and 21 countries investigates how entrepreneurs responded to the Covid-19 pandemic and which cognitive frames guided their actions. Observed cognitive frames prioritize either business survival, conversion of business and stakeholder interest, or acceptance of conflicting social and financial goals. These cognitive frames influence the choice of crisis response without determining it. Four response patterns were found: weathering the storm, bricolage, solidarity and support, and social innovation. Strategic innovation creating access to new markets is the most successful response. The findings support a more encompassing definition of the concept of organizational resilience and shed light on motivations for acts of solidarity and social innovation as crisis responses.

Our knowledge of international expansion motives and strategies of emerging country banks (ECBs) is limited. Using a worldwide sample of cross-border mergers and acquisitions (CBMAs) and a mixed model, we explore firm- and country-level determinants of acquisition premiums. We show that the effects of target bank and target country characteristics on premiums are contingent on the acquirer’s home country: emerging vs. advanced. More specifically, compared to advanced country acquirers, ECBs pay lower premiums for targets that are: (i) more efficient; (ii) offering better functional diversification opportunities; and (iii) based in markets with higher growth prospects or better institutional development levels. Furthermore, state-owned ECBs pay higher premiums. Our findings suggest that CBMAs undertaken by ECBs might not be motivated by competence-enhancing strategies while being less sensitive to the target country’s institutional development.

This paper explores geographic diversification strategies’ impact on multinational banks’ operational performance within the context of research on globalization and regionalization. We employ a sample of the 49 largest banks from 16 European countries from 2011 to 2018 and proxy operational performance by technical efficiency. We find the impact of geographic diversification on operational performance depends on the locus of geographic diversification—home-regional vs. inter-regional—and the interplay between geographic diversification and banks’ functional focus. More specifically, home-regional diversification together with a concentration on non-interest income-generating activities, including fee and commission and trading income, worsens performance, and diversification across regions alongside a focus on non-interest income-generating activities improves performance. Distinct product characteristics’ ability to facilitate different regional dispersions has important managerial implications for enhancing the success of geographic diversification strategies, a central but unresolved issue in global banking.

For effective supply chain management, firms should focus on the relationship with their immediate stakeholders in the supply chain, namely, suppliers (upstream) and customers (downstream). This study investigates the impact of customer and supplier concentration as well as business strategy on sustainable financial growth, using financial data of 2021 Chinese non-financial firms listed from 2006 to 2020. Additionally, it explores the moderating effect of business strategy on the relationship between customer and supplier concentration and sustainable financial growth. We find that higher customer and supplier concentration weakens the bargaining power of Chinese firms, which reduces their financial growth. However, an appropriate business strategy can help such firms achieve sustainable financial growth. We find that an aggressive business strategy moderates the negative impact of supplier concentration, while a defensive business strategy moderates the negative impact of customer concentration on financial growth. Finally, our results for the direct impact of customer and supplier concentration as well as business strategy hold for state-owned and non-state-owned firms. However, we find differences regarding the moderating impact of business strategy between state-owned and non-state-owned firms. Our results are robust to time and industry fixed effects, alternate proxies of financial growth and regression techniques

Literature around middle management has highlighted the importance of intra-organizational boundaries, focusing on the in-betweenness and fluidity of middle-managerial roles and practices. Yet, this literature has largely focused on the crossing of largely stable, monolithic boundaries, placing less emphasis on the plurality of emerging boundaries and the ways in which they are constructed. Focusing on boundaries as the outcomes of, rather than only as constraints upon, everyday practices, we conduct an ethnographic study across multiple sites of a Brazilian audit firm, examining middle managers’ construction, maintenance and adjustment of boundaries. Drawing upon ethnographic fieldnotes and 155 formal interviews, our study reveals how middle managers fluidly manipulate boundaries’ visibility and permeability to achieve specific purposes, and how different configurations of these elements generate various boundary work practices, which we describe as barricade, façade, taboo and phantom boundary work. Moreover, we show the dual orientation of middle managers’ boundary work –both obstructing and facilitating boundary-crossing –demonstrating that, in contrast to prior research, both orientations can be enacted by the same actor according to his or her purposes. By doing so, we contribute to scholarship exploring agency and plasticity as the key issues linking the existing literature on middle management with that on boundary work.

Scholarly interest in research on travelers’ psychological ownership has recently increased given its relationship with traveler behavior. This study provides a systematic literature review centered on travelers’ psychological ownership, thus organizing extant work and developing guidelines for future research. We employ bibliometric analysis to reveal current research progress in the domain, acknowledge influential contributions, and identify major research streams. Then we use framework-based thematic analysis and develop a Targets-Antecedents-Consequences-Interventions (TACI) framework to explore the theoretical underpinning of travelers’ psychological ownership, yielding structural insights and knowledge gaps. Based on our review, we develop 18 propositions to guide future research. The findings provide academics with a roadmap to advance research on travelers’ psychological ownership.

We compare two approaches in their ability to solve for optimal Ramsey policies in heterogeneous-agent models, considering the optimal provision of a public good. First, the “transition” approach makes the problem tractable by assuming a constant path for the planner’s instruments. Second, the “truncation” approach uses a Lagrangian technique, solving the Ramsey problem of a finite state space model that approximates the full model. The truncation approach is shown to compute quantitatively accurate estimates of the actual values of the planner’s instruments, whereas a time-inconsistency issue is found to affect the transition approach.

In modern production–distribution supply chains, decentralization has increased significantly, due to increasing production network efficiency. This study investigates a production scheduling and vehicle routing problem in a make-to-order context under a decentralized decision-making structure. Specifically, two different decision makers hierarchically decide the production and distribution schedules to minimize their incurred costs and we formulate the problem as a bi-level mixed-integer optimization model as a static Stackelberg game between manufacturer and distributor. At the upper level, the manufacturer decides its best scheduling under a flexible job-shop manufacturing system, and at the lower level, the distributor decides its distribution scheduling (routing) which influences the upper-level decisions. The model derives the best production–distribution scheduling scheme, with the objective of minimizing the cost of the manufacturer (leader) at the lowest possible cost for the distributor (follower). As the lower level represents a mixed-integer programming problem, it is challenging to solve the resulting bi-level model. Therefore, we extend an efficient decomposition algorithm based on Duplication Method and Column Generation. Finally, to discuss the decentralization value, the results of the presented bi-level model are compared with those of the centralized approach.

Project management (PM) career choice is important as millions of new projects will need skilled and motivated project managers. Therefore, the younger generation must be motivated to acquire the necessary skills to deal with project complexities and dynamics. In previous research, the factors that impact students’ perceptions of their learning experiences and their readiness to PM work has been investigated without examining the factors that impact the choice of a PM career. In this study our aim is to describe the intentions and motivations of business school students to pursue a PM career. Our results demonstrate that motivations such as self-development, professional growth, status and power, and technical and human skills are significantly influential in PM career choices.

Whilst a multitude of studies explored the financial implications of corporate brand equity in a B2C context, little is known as to the financial impact of B2B brand equity. Furthermore, no study, to our knowledge, has examined how climate change-related corporate practices affect the nexus between B2B brand equity and financial aspects (i.e., creditworthiness) of B2B firms. Drawing propositions from the resource dependence theory (RDT) and the natural resource-based view of the firm (NRBV), this study develops a parsimonious conceptual model to investigate the relationship between B2B brand equity and a firm’s long-term creditworthiness. Given B2B firms’ increasing engagement in pro-environmental initiatives, the model also incorporates a firm’s ability to recognize climate change-related commercial risks and opportunities as a moderator. Drawing samples from USA-based B2B firms, the conceptual model is tested through robust econometric modelling techniques. The results demonstrate that higher B2B brand equity leads to higher long-term creditworthiness of a firm. Further, the positive association between B2B brand equity and creditworthiness is accentuated by climate change commercial risks and opportunities recognition (CCCROR). That is, a firm’s capacity to identify challenges and opportunities emanating from the inexorable global climate change further bolsters the positive link between industrial brand equity and long-term creditworthiness. These findings are robust to a battery of sensitivity analyses, including multi-level mixed effect and endogeneity-robust modelling techniques.

  • Vichiengior, T., Ackermann, C.-L., Palmer, A. (2023) Consumer anticipation as a performative experience. European Journal of Marketing, Vol. 57 No. 11, pp. 3005-3039.

The purpose of this study is to explore consumer anticipation processes that occur after commitment to a purchase has been made, but before consumption occurs. The authors add to the knowledge and theory building about anticipation that occurs in this liminal phase by investigating the cognitive, emotional and behavioural processes that interact to influence post- consumption evaluations. An abductive research approach used a phase-based research design using semi-structured interviews. The authors identify interactions between cognitive, emotional and behavioural processes that occur during anticipation and associate these with post-consumption outcomes. Anticipation of a consumption experience, enacted through thoughts, emotions and actions, and undertaken with peers, is an experience per se, independent from and interdependent with the substantive experience, and contributes to performance of the substantive experience. The authors propose a framework in which anticipation – as a performative phenomenon – influences the overall evaluations of the substantive consumption experience in contexts of delayed consumption. The theoretical grounding of performativity makes a useful contribution through its linkage of thought processes to outcomes. The authors further locate their findings within the literature on attribution theory. By engaging in anticipation, informants perceived the locus of causality to be internal, and expressed pride in having anticipated if the subsequent experience was successful. By anticipating, informants perceived an ability to exert control over future events and felt ashamed of not having adequately anticipated if an experience was subsequently unsuccessful.

Practical implications – The authors discuss the trade-off service providers face between encouraging anticipation, which raises expectations that might not be met, and facilitating anticipatory preparations, which may reduce the risk of service failure. The authors provide a new lens by conceptualising anticipation as a performative process and identifying mechanisms by which anticipation is embedded in total consumption experience. This study has important generalisable implications for contexts where mechanisms of performative anticipation may be a means for ameliorating uncertainty about future consumption experiences.

This study explores how middle managers deal with knowledge inflows whilst striving to achieve ambidexterity. This is enabled through a two dimensional conceptual framework involving knowledge sources (vertical or horizontal) and acquisition activities (structural and contextual). We based our study upon interviews conducted with 64 managers from hypermarket retailers in China, in addition to field observations and secondary data. Our findings reveal that these middle managers leverage different combinations of structural and contextual mechanisms to govern the vertical (top-down and bottom-up) knowledge inflows within their business units. Structural mechanisms comprise differentiation and integration. For their part, contextual mechanisms consist of a combination of discipline, stretch, support and trust. These combinations also enable horizontal knowledge inflows to be managed from outside the business unit. These also enable middle managers’ ambidexterity, first at the business unit level and second at the organization level. Our findings offer managerial guidelines for handling knowledge inflows from various sources and with different patterns. They also assist middle managers with their contribution to their firms’ pursuit of organizational ambidexterity.

The authors characterize the conditions under which a country may eventually split and when it splits within an infinite horizon multi-stage differential game. In contrast to the existing literature, the authors do not assume that after splitting, players will adopt Markovian strategies. Instead, the authors assume that while the splitting country plays Markovian, the remaining coalition remains committed to the collective control of pollution and plays open-loop. Within a full linear-quadratic model, the authors characterize the optimal strategies. The authors later compare with the outcomes of the case where the splitting country and the remaining coalition play both Markovian. The authors highlight several interesting results in terms of the implications for long-term pollution levels and the duration of coalitions under heterogenous strategies as compared to Markovian behavior. In this paper, the authors have illustrated the richness of the simplications of enlarging the set of strategies in terms of the emergence of coalitions, their duration and the implied welfare levels per player. Varying only three parameters (the technological gap, pollution damage and coalition payoff share distribution across players), the authors have been able to generate, among other findings, quite different rankings of welfare per player depending on whether the remaining coalitions after split play Markovian or stay precommited to the pre-splitting period decisions.

  • Jia LI, Bouraoui, Taoufik, Magdalena Radulescu (2023) On the drivers of sustainable development: empirical evidence from developed and emerging markets. Applied Economics, Volume 55, Issue 57, pp. 6809-6821

Why do firms’ sustainability disclosure performance differ so much between firms and across countries? Which factors drive firm’s awareness of sustainable development and do these factors have different driving mechanisms between developed and emerging countries? We answer these questions using a panel data regression model on around 1500 companies from 20 developed countries and 20 emerging countries during the period from 2009 to 2019. Our empirical results reveal that both firm-level and country-level variables are important predictors for sustainable disclosure performance. In developed countries, most firm-level indicators show a significant and positive effect on Environmental, Social and Governance (ESG) disclosure scores. In emerging countries, only operating performance, measured by total revenues, and firm size have a positive impact on ESG disclosure, while high level of profitability is associated with low ESG score. On the country level, we find a significant relationship between all drivers and ESG scores in developed countries. However, in emerging markets, only economic, cultural (excepting uncertainty avoidance index) and technological factors are shown to impact significantly sustainable development

  • Farnaz Khoshgehbari, S. Mohammad J. Mirzapour Al-e-Hashem (2023) Ambulance location routing problem considering all sources of uncertainty: Progressive estimating algorithm. Computers & Operations Research, Volume 160, 106400

The main concern of any emergency medical services (EMS) in the world is to provide quality services to emergency calls in the shortest possible time. In this paper, the Ambulance Location Routing problem (ALRP) is proposed that is a mathematical attempt to obtain optimal cost-oriented strategic decisions (locating EMS centers and allocating ambulance fleet) in a way that guarantees service quality factors like response time, service level, and definite treatment time through optimal ambulance routing. In response to the concerns that emergency medical services deal with, in this research, a novel mixed-integer two-stage stochastic programming model is developed that can consider the uncertain nature of parameters like emergency calls, travel times, and pathways, simultaneously. Considering a heterogeneous fleet of ambulances to provide specialized out-of-hospital services and to use the treatment golden time, and considering different types of patients in terms of the need to be transferred to the hospital, are among the most vital innovations of the proposed ALRP. To tackle the computational complexity, a new decomposition-based heuristic method called the Progressive Estimating Algorithm (PEA) is developed. PEA is a modified version of the classic PHA and solves its drawbacks, like the possibility of being placed in a loop or prolonging the solution time by changing the method of calculating the first stage variables in each iteration. Therefore, by considering a large number of scenarios, PEA can reach feasible near-optimal solutions more efficiently. We have employed the actual data of a city with nearly 800.000 population, as a case study to validate the proposed ALRP model and the PEA method. The obtained results demonstrate that the proposed ALRP solution is valid, and the PEA can reach the near-optimal solution, in a very reasonable time, and with no exception, outperform the PHA. The results also show that the ALRP model reduces costs on average by 30% compared to a benchmark model. In addition, it is found that the solution obtained for the case study can reduce costs by 58% compared to the current state of the EMS in this city while guaranteeing the quality of services. Furthermore, the need to use a heterogeneous fleet of ambulances and scattered stations in the region is recommended to improve the performance of EM services. Finally, the unique way of looking at the integrated problem of location, allocation, and routing in the proposed ALRP and the idea of PEA are attractive for further studies in the field of EMS planning and other optimization problems, and several suggestions for future studies are mentioned in Conclusion Section

Executive social irresponsibility has received increasing research attention in recent years, following the consensus for a broader stakeholder approach to managerial decision making. Despite the importance of the subject, there remains insufficient research on contextual factors that mold executives’ orientation toward social responsibility. Through three studies, we demonstrate that difficult business goals can reduce executives’ tendency to consider social responsibility in their decision making. Further, we find that focalism—a cognitive bias based on affective forecasting theory—can mediate positive relationships between business goal difficulty and socially irresponsible executive behavior. Our findings also suggest that, expanding executives’ thought processes beyond the narrow focus of a business goal achievement can be a good strategy in reducing socially irresponsible executive behavior, even in the presence of difficult goals.

Firms are increasingly adopting pro-lesbian, -gay, -bisexual, -transgender, inclusivity and diversity (LGBT-ID) policies for workforce management. This study develops a parsimonious, albeit complex, moderated-mediated framework by employing a panel dataset combining data from archival sources and involving a sample of predominantly large and publicly held firms from the USA between 2002 and 2018. The number of observations varied across variables with a minimum of 414 observations (corporate brand equity) and a maximum of 3,566 observations (self-reported LGBT-ID policy). This treatise demonstrates that adopting LGBT-ID policies positively impacts firms’ profitability. Moreover, pro-LGBT-ID policies during this specific period have a positive effect on corporate brand equity, which in turn affects firm profitability, indicating that brand equity plays a mediating role in the nexus between pro-LGBT-ID policies and firms’ financial performance. Furthermore, innovation intensity strengthens the relationship between pro-LGBT-ID policies and brand equity during the sample period of the study.

This paper studies the green new product development (GNPD) problem of a risk-averse capital constrained supply chain (SC). The SC is managed by an SME entrepreneur, seeking financial support from a multi-sided FinTech platform (MSP) to develop a portfolio of green and non-green products. The MSP offers the SC a combination of equity financing (EF) and debt financing (DF) facilities and must decide on the interest rate of its DF facility. Using a benchmark model, we first characterize the SC’s production and the MSP’s financing decisions under a deregulated scenario. Focusing on an alternative case with government intervention (i.e., hybrid environmental-green entrepreneurship policy), we next develop a three-level game theoretical model and sequentially characterize the decision-making behavior of government,MSP, and SC. The model outcomes are analyzed by considering the policy approach (i.e., economic influence vs. social welfare) and the platform’s risk attitude. The results reveal that, when coupled with an appropriate government intervention policy, a regulated scenario leads to a better outcome, particularly when the MSP is risk-neutral and strikes a right balance between the EF and DF. The win–win situation may not be realized when the MSP is risk-averse and the host government is merely focused on its economic influence. To successfully promote sustainable supply chain finance (SSCF) through digital platforms, policy makers are urged to leverage their legislative power and prioritize green entrepreneurship and social welfare over their financial maximization agenda.

Online shopping addiction has become a worsening problem in China for males and females. Based on 904 shoppers, this study examines the relationship between hedonic shopping motivations and compulsive online buying and investigates gender differences using gender theories. This study finds that different hedonic motivations contribute to compulsive online buying. Gratification seeking and idea shopping are key motivations for compulsive online buyers (females are mostly gratification seekers, while males are mostly information seekers). Conversely, value and role-play shopping reduce compulsive online buying, with a stronger effect on females; however, role-play shopping was unrelated to compulsive online buying for males.

We apply a multivariate mixed-data sampling (MIDAS) conditional quantile regression technique to understand the dairy commodity exposure of European dairy firms. Leveraging a theoretically sound hedonic dairy pricing framework, we show that our approach is able to identify both market and operational risk. Profit margins for butter and milk price are particularly important for operational performance. Additional tests are provided, including an application of MIDAS quantile on a period of amplified dairy market risk. Our approach thus allows dairy firms to gain new perspectives on the significant risks posed by the current structure of dairy production in Europe.

We construct a spatiotemporal frame for the study of spatial economic and ecological patterns generated by transboundary pollution. Space is continuous and polluting emissions originate in the intensity of use of the production input. Pollution flows across locations following a diffusion process. The objective functional of the economy is to set the optimal production policy over time and space to maximize welfare from consumption, taking into account a negative local pollution externality and the diffusive nature of pollution. Our framework allows for space and time dependent preferences and productivity, and does not restrict diffusion speed to be space-independent.  Accordingly, we develop a methodology to investigate the environmental and economic implications of spatiotemporal heterogeneity. We propose a method for an analytical characterization of the optimal paths. An application to technological spillovers is proposed for illustration. We focus on the determination of the optimal short-term spatiotemporal dynamics induced by the resulting non-autonomous problems

The purpose of this study is to investigate the development of brand hate based on the case of Italian luxury fashion house Dolce & Gabbana in China. The strategy adopted in this study is a single in-depth case study. Qualitative methods are applied in both the data collection and analysis. The findings identified six distinct stages through which brand hate can develop: awareness, anger, amplification, antagonism, action and apathy. The case is specific to a luxury brand and the Chinese cultural context. Practitioners need to consider how business strategies can be adapted to manage the six stages of the manifestation of brand hate. A “proactive” approach is needed to avoid arousing brand hate, while a “reactive” approach is needed to manage its potential ramifications. There has been a paucity of anti-consumption research within the business strategy literature. To the best of the authors’ knowledge, the focus on China makes this the first study to investigate brand hate within a Chinese cultural contex.

  • Thomas Conlon, John Cotter, Emmanuel Eyiah-Donkor (2022) The illusion of oil return predictability: The choice of data matters! Journal of Banking & Finance, Volume 134, 2022, 106331

Previous studies document statistically significant evidence of crude oil return predictability by several forecasting variables. We suggest that this evidence is misleading and follows from the common use of within-month averages of daily oil prices in calculating returns used in predictive regressions. Averaging introduces a bias in the estimates of the first-order autocorrelation coefficient and variance of returns. Consequently, estimates of regression coefficients are inefficient and associated t-statistics are overstated, leading to false inference about the true extent of in-sample and out-of-sample return predictability. On the contrary, using end-of-month data, we do not find convincing evidence for the predictability of oil returns. Our results highlight and provide a cautionary tale on how the choice of data could influence hypothesis testing for return predictability.

A two-stage decentralized supply chain operates in make-to-order under a stochastic environment. Each stage represents an independent firm that quotes a price and a delivery time to its downstream while satisfying a minimum service level. The mean demand depends on the final price and the overall delivery time quoted to the customers by the whole supply chain. We study three settings. First, the downstream, as a Stackelberg leader, decides its price and controls both delivery times, and the upstream, as a follower, reacts by deciding its own price. Second, the downstream decides its delivery time and controls prices, and the upstream reacts by quoting its own delivery time. Third, the upstream, as a leader, decides its price and controls both delivery times, and the downstream, as a follower, decides its own price. This is the first study to investigate the delivery time quotation and pricing in decentralized supply chains where each firm performs operations and has a delivery time, and the demand is function of both upstream and downstream delivery times in addition to final price. We characterize analytically the optimal strategy under each setting and derive insights into the interplay between local delivery times, overall delivery time, prices, demand, and profits. We investigate how delivery times can be used to coordinate the supply chain and the impact of firms’ capacities.

This paper examines and compares financial market reaction and recovery of four broad classes of financial assets – equity indexes, precious metals, 10-year benchmark bonds and cryptocurrencies, to the COVID-19 pandemic. The data set comprises daily observations of close prices in the selected markets from 17-04-2018 to 20-06-2021. Using the Yang and Zhao (2020) and Koenker and Xiao (2004) quantile unit-root tests for return persistence, we find heterogeneity in reactions and recovery patterns not only across asset classes, but also within them. Specifically, we find strong potential for mean reversion in equity markets even at high levels of shocks. While gold offers limited mean reversion, platinum shows very strong resistance to the COVID. Government bonds show small declines in value to the COVID in addition to high persistence. Cryptocurrencies, as a group, turn out to be the riskiest in the long-term, with more than a 50% decline in value coupled with high degrees of persistence. Our results raise questions as to the safe haven characteristics of the newly-popular Bitcoin. Our findings are useful for policy makers and investors through a better understanding of differences in the potential for mean reversion provided by different asset classes.

Transportation Journal 1 January 2022; 61 (1): 60–102

The production routing problem seeks to simultaneously optimize production, routing, and inventory decisions for the plant and the suppliers. In this article an integrated multi-objective sustainable pricing-production-workforce- routing problem is presented for perishable products. Total profit, workforce planning, and vehicle fuel consumption are considered as objective functions due to the importance of operational performance, social, and environmental concerns. The application of the proposed approach is investigated using real case data from a dairy product supply chain. Furthermore, a new solution approach, called Fuzzy Domination Self- Learning Non-Dominated Sorting Algorithm (FDSL-NSGA-II), is developed to solve the problem. The results show that the Pareto solutions of FDSLNSGA- II outperform those of the classic NSGA-II. Moreover, the findings show that the proposed model can create a surpassing tradeoff between the various aspects of a supply chain, including production, distribution, and workforce planning. In addition, it concurrently optimizes the selling price and protects the environment from the negative impacts of greenhouse gas.

Digital adoption has been accelerated by the COVID-19 pandemic; companies have been challenged to rapidly adapt to the constant evolution of consumer needs and expectations, leading to valuable insights into the advancement of green business practices and a consequent rethinking of their business model. The purpose of this paper is to investigate the major shifts in sustainable consumer behavior on the Romanian retail market within the context of the Green European Deal, and retailers’ priorities in agilely adapting to these significant evolutions. Based on a comprehensive literature review on these major shifts and significant evolutions at the national and international levels, a quantitative study was carried out to evaluate the Romanian retail market and identify the major challenges faced by retailers in dealing with the new set of priorities. The data collection was conducted via a survey used in the retail environment, applied within a Romanian supermarket chain. The Romanian retail sector has a particular configuration, which may have an impact upon the study’s generalizability. Located in Central and Eastern Europe at the crossroads of the EU, the Commonwealth of Independent States (CIS), and the Middle East, Romania is a leading destination for foreign direct investment, and it is recognized for the similarities of its distribution and sales channels, the range of its retail outlets, and the local retail market dominance on the Big Box segment by reputed major retailers. A spectacular evolution is recorded in Romania’s e-commerce market, including from the point of view of the long-standing and memorable traditional relationship between Romania and China which was confirmed more recently by Romanian consumers who prefer to buy online from stores in China. Our consumer research provides retailers with deep consumer insights with regard to their priorities in their agile adaptation. According to our research, Romanian consumers are environmentally concerned consumers, displaying an increased awareness about the important role they play with respect to impacting sustainable production and consumption by adopting green purchase behavior. Our study also points to the fact that retailers, although faced with challenges in targeting consumers with customized messages to reinforce their brand perception on sustainability issues, do pay considerable attention to sustainability as a personal value embraced by consumers and are willing to focus on digitizing their business processes to enable new, sustainable business models

Negative customer engagement (NCE) has received little research attention. The effect of NCE on market-based assets (i.e. brand equity) and firm performance remains a particularly underexplored topic despite the increasing rates of NCE with brands across a multitude of service industries. This study develops a comprehensive and parsimonious model of the causes and consequences of NCE. In this study, time-series cross-sectional data from the US airline industry and a simultaneous equation modelling technique were used to provide evidence for why some firms experience more NCE than others. The results indicate that airlines with a higher relative marketing capability (RMC) experience fewer NCE incidents in the form of customer complaints. A firm’s relative marketing capability determines the extent to which its customers engage negatively with it. Furthermore, deviating from earlier studies which explored the direct and immediate relationships between the focal variables, this study theoretically argued and empirically demonstrated that brand equity mediates the nexus between NCE and financial performance. That is, the number of NCE incidents a firm experiences affects its brand equity, which in turn impacts its financial performance, as measured by Tobin’s q and market value added (MVA).

Should we teach in hybrid mode or fully online? We examine the teaching model’s role (hybrid versus fully online) in the service–profit chain in higher education institutions using survey data from 93 faculty members and 366 students from three American universities. We find that faculty members’ satisfaction and the MBA program expectations improve MBA word-of-mouth by enhancing the MBA quality, MBA value, class satisfaction, and MBA loyalty. Additionally, we discover that the hybrid teaching model more strongly reinforces this chain of effects than the fully online model. IT creates the integration of differential value into a hybrid teaching style.

Recent developments in the innovation literature suggest that even when an organization truthfully implements the adopted R&D policy, it may still fail to achieve its intended goals, a phenomenon called means-ends decoupling. We employ a systematic literature review to answer the question of “what is the current state of knowledge in the phenomenon of means-ends decoupling in the literature” and “where it can move in the future.” Our paper provides a framework that delineates means-ends decoupling from policy-practice decoupling and identifies the underlying mechanisms that explain when and how means-ends decoupling may occur within an organization’s activities.

This study investigates challenges and opportunities that regionally expanding emerging market banks face. We focus on four leading Middle Eastern banks’ internationalization trajectories and performances by employing a case study approach. We first examine the four banks’ choices of target markets, entry sequencing, and  entry modes over time and then analyze their entry strategies and post-entry financial performances in one of their key markets, Turkey. We show that the success of regional expansion strategies depends on parent bank characteristics such as scale and capital strength, strategic decisions regarding entry mode and timing, and host market structure and competitiveness.

This research identifies how windows of opportunity (WOP) emerge and influence the catching up process of the Chinese electric vehicle (EV) industry between 1995 and 2018 by analyzing technological, institutional, and market demand elements of the WOP. Our case study indicates that government policies play a vital role. Along with the development of Chinese EV industry, government policies evolve from initiation to consolidation and finally reposition. Meanwhile, WOP emerge but diverge in their patterns; from institutional to technological and finally to the market demand WOP. Our study further elaborates the interplay of the above-mentioned three kinds of WOP, which provide feedback to the government authorities and work jointly to facilitate the catching up of Chinese EV industry. Based on the evidence of the Chinese EV industry, we continue the discussion of the emergence and interplays of WOP during the industrial catching up in latecomer countries like China, who is eager to build an energy-saving industry. Our case study provides a fine-grained analysis of policy evolution and its role in opening the different kinds of WOP, which eventually contribute to the successful catching up of a latecomer industry. It also offers new insights for policymakers when building a sustainable system

Academic scientists are encouraged to pursue research that delivers both scientific and societal impact. This may involve a search for alternative mechanisms of social approval which lead to endorsement of scientists’ research goals. We explore how scientists mobilise and accumulate different forms of legitimacy, which might favour their participation in practices related to innovation and societal impact. We propose three specific sources of scientific legitimacy: i) scientists’ social networks (research-related legitimacy ties), ii) prominence in the relevant academic community (reputation-based legitimacy); and direct contact with the primary beneficiaries of the research (beneficiary-based legitimacy). To explain scientists’ participation in activities oriented towards innovation and societal impact, we test the significance of each of these sources of legitimacy and their potential interplay empirically, using a large sample of Spanish biomedical scientists

This article investigates the theoretical and empirical relationships between organisational punishment and productivity. We do so by highlighting the contributions of two academic fields to this topic: management and economics. We underscore the many common theoretical and empirical grounds across management and economics. We heighten, in particular, how motivation and learning theories have contributed to the development of both theoretical and empirical research on this topic. This article also argues that this debate could be significantly advanced if insights stemming from industrial relations and labour process theory were also considered, as these disciplines have traditionally focused on macro-issues such as how changes in the economic/institutional contexts may affect the likelihood that organisations will resort to unishment. In order to foster future research on this topic, three research themes were developed: (a) freedom of choice and the role of contract completeness; (b) perception of punishment, monitoring and productivity; and (c) punishment, productivity and exogenous variables.

Industrial Marketing Management, Volume 101, 2022, Pages 258-271

This empirical study analyzes how strategic orientations influence the relationships between exploration and exploitation-related networking capabilities, foreign market knowledge, and market performance of 198 internationally operating firms in Bangladesh. The results of hierarchical regression showed that a higher level of network exploration capability and network exploitation capability individually generate greater foreign market knowledge. In addition, our results show that international entrepreneurial orientation reinforces the positive effect of network exploration capability. The positive association between market knowledge and performance, in turn, is accentuated by a proactive export market orientation but attenuated by a responsive export market orientation. These findings suggest that, while both types of networking capabilities are beneficial to develop stocks of foreign market knowledge, firms can acquire and create greater knowledge if they strategically align entrepreneurial orientation with network exploration capability. Further, to use this market knowledge with the goal of improving their position in international markets, firms need to develop a proactive rather than a responsive export market orientation. The current study contributes to the literature on networking capabilities by analyzing firms’ networking capabilities with the lens of exploration-exploitation typologies and incorporating strategic orientations as the contextual factors of such capabilities

  • Amirhossein Sadoghi, Jan Vecer (2021) Optimal liquidation problem in illiquid markets. European Journal of Operational Research, Volume 296, Issue 3, 2022, pp 1050-1066

In this research, we develop a trading strategy for the optimal liquidation problem of large-order trading, with different market microstructures, in an illiquid market. We formulate the liquidation problem as a discrete-time Markov decision process. In this market, the flow of liquidity events can be viewed as a point process with stochastic intensity. Based on this fact, we model the price impact as a linear function of a self-exciting dynamic process. Our trading algorithm is designed in such a way that when no favourite orders arrive in the Limit Order Book (LOB), the optimal solution takes offers from the lower levels of the LOB. This solution might contradict conventional optimal execution methods, which only trade with the best available limit orders; however, our findings show that the proposed strategy may reduce final inventory costs by preventing orders not being filled at earlier trading times. Furthermore, the results indicate that an optimal trading strategy is dependent on characteristics of the market microstructure.

Applied Economics R&D investments: a quantile regression approach. Applied Economics, 54:17, 1974-1988

This study investigates the impact of financial flexibility and academic experience of a firm’s board on corporate R&D investments in China. It also explores the moderating role of directors’ academic experience on the relationship between financial flexibility and R&D investments. We apply ordinary least square, fixed effects and quantile regression analysis using panel data of 2,195 A-share firms listed on Shanghai and Shenzhen stock exchanges during the period from 2011 to 2018. We find that both financial flexibility and directors’ academic experience promote R&D investments of Chinese non-financial firms. We also observe that directors’ academic experience weakens the positive impact of financial flexibility on R&D investments for firms operating in underdeveloped financial regions, whereas it strengthens the positive impact of financial flexibility on R&D investments for firms operating in developed financial regions. Our quantile regression results suggest that academic experience has a highly significant positive moderating impact on the financial flexibility of lower R&D investment firms relative to high R&D investment firms. These results are robust to alternate proxy of financial flexibility and endogeneity issues due to reverse causality.

Using a large panel dataset of 861 listed Chinese firms, the present study investigates whether corporate social responsibility (CSR) affects firm-value. It examines the influence of five CSR dimensions on firm-value. Then, it pinpoints the moderating impact of industry-sensitivity and power concentration of the CEO. In contrast to developed economy’s evidence, the results show an overall negative impact of CSR on firm-value. Looking closer at the dimensions separately, we find a negative impact of most of the CSR dimensions and a positive impact of some other CSR dimensions on firm-value. However, we observe that CSR enhances the value of firms operating in sensitive industries. Similarly, we find that a powerful CEO can also create firm-value through CSR by aligning CSR practices with the firms’ objectives. Our results are sufficiently rigorous to alternate proxies of CSR.

By combining expatriate social support and online community literature, we explore the role Internet-based expat platforms can play in creating complementary opportunities of interaction leading to informational, emotional and instrumental support for expatriates in the host country. For this purpose, two studies were conducted: 1) a text analysis using computational linguistic methods for 13 500 posts from 45 expat platforms to find evidence of different kinds of social support based on the type of platform; 2) an online survey distributed to gather insights on expatriates’ types of participation and the types of social support they receive. We find that relations generated through virtual platforms – which we call platform contacts – are complementary sources for expatriates to obtain informational, emotional, and instrumental support, the latter two being higher for hybrid participants, i.e. for those who use online and offline features of the platform. This study further presents that expatriates who receive social support from platform contacts also show higher sustained participation, especially if they are hybrid participants. Based on these results, we present a dynamic model with testable propositions and discuss implications.

  • Yashar Bashirzadeh, Robert Mai, Corinne Faure (2021) How Rich is Too Rich? Visual Design Elements in Digital Marketing Communications. International Journal of Research in Marketing, Issue #1 Vol 39 (March 2022) pp 58 -76

Companies are increasingly including innovative visual design elements such as animations and pictographs in digital communication. While both elements can be beneficial in exchanges with their customers, we propose that combining them can have negative effects on communication effectiveness. Animations and pictographs enhance digital communication, essentially through increased perceptions of enrichment, but these elements also raise perceptions of clutter. As they enrich a message in unique ways, processing these different types of visual design elements requires distinct cognitive resources such that, when combined, clutter perceptions dominate the recipient’s perceptions and behaviors, thus paradoxically offsetting their positive effects. This interplay may not only undermine message outcomes but even spill over to downstream behavioral outcomes. In a large-scale randomized field experiment in cooperation with a mobile app company, we find that including animations (GIFs) and pictographs (emojis) together damages message outcomes (increasing unsubscriptions) and downstream outcomes (reducing in-app time) compared with what happens when these elements are deployed separately.We elaborate on the processing of the text and visual elements from this field experiment in two lab experiments, including an eye-tracking study. Finally, in two further online studies, we seek to establish whether the proposed mechanisms depend on the number of visuals or the types of pictographs employed.

We characterize the shape of spatial externalities in a continuous time and space differential game with transboundary pollution. We posit a realistic spatiotemporal law of motion for pollution (diffusion and advection), and tackle spatiotemporal non-cooperative (and cooperative) differential games. Precisely, we consider a circle partitioned into several states where a local authority decides autonomously about its investment, production and depollution strategies over time knowing that investment/production generates pollution, and pollution is transboundary. The time horizon is infinite. We allow for a rich set of geographic heterogeneities across states. We solveanalyticallythe induced non-cooperative differential game and characterize its long-term spatial distributions. In particular, we prove that there exist a Perfect Markov Equilibrium, unique among the class of the affine feedbacks. We further provide with a full exploration of the free riding problem and the associated border effect

In this paper, we study the role of narratives in stock markets with a particular focus on the relationship with the ongoing COVID-19 pandemic. The pandemic represents a natural setting for the development of viral financial market narratives. We thus treat the pandemic as a natural experiment on the relation between prevailing narratives and financial markets. We adopt natural language processing (NLP) on financial news to characterize the evolution of important narratives. Doing so, we reduce the high-dimensional narrative information to few interpretable and important features while avoiding over-fitting. In addition to the common features, we consider virality as a novel feature of narratives, inspired by Shiller (Am Econ Rev 107:967–1004, 2017). Our aim is to establish whether the prevailing narratives drive or are driven by stock market conditions. Focusing on the coronavirus narratives, we document some stylized facts about its evolution around a severe event-driven stock market decline. We find the pandemic-relevant narratives are influenced by stock market conditions and act as a cellar for brewing a perennial economic narrative. We successfully identified a perennial risk narrative, whose shock is followed by a severe market drop and a long-term increase of market volatility. In the out-of-sample test, this narrative went viral since the start of the global COVID-19 pandemic, when the pandemic-relevant narratives dominate news media, show negative sentiment and were more linked to “crisis” context. Our findings encourage the use of narratives to evaluate long-term market conditions and to early warn event-driven severe market declines.

Textile waste is one of the most pollutant items globally, being strongly affected by fast fashion (FF) products. Public pressure has made many FF firms voluntarily collect a small fraction of their preowned items and export them to developing countries for reuse. However, some developing countries are launching import bans on second-hand clothes. In addition, FF firms may soon be forced by extended producer responsibility legislation to collect more preowned items for reuse and recycling. To date, they do not have sufficient capacity to deal with this. Charities have been the key collectors and recyclers of unwanted clothes. Therefore, charities could help FF firms increase their capacity in this reverse supply chain (SC). However, we hardly witness such a collaboration for two main reasons: (i) charities prefer to sell high-quality preowned items in the primary market to generate the highest possible revenue and FF firms may fear cannibalization, (ii) many charities believe that FF firms generate quantities of low-quality items that require collection and sorting while being difficult to sell in the primary market. Charities also face competition from many small for-profit organizations selling FF preowned items. While charities have the support of volunteers, they tend to be less efficient. This work urges Operations Management (OM) researchers to suggest innovative business models to help (i) FF firms and charities collaborate to solve the abovementioned issues, and (ii) charities to improve their traditional practices for competitiveness. This study is primarily a position paper highlighting some challenges and introducing interesting research problems. Although the paper is not a research paper, it follows a qualitative research method to collect and analyze the required supporting documents to justify arguments and statements. We collected primary and secondary data from the textile reverse SC members to familiarize the OM community with this context. The current changes in the textile reverse SC offer many great opportunities for impactful OM research.

In this paper, we examine the changes in the dependence structure of global stock markets amid the outbreak of COVID-19. We divide 56 stock markets into developed, emerging, and frontier markets and study their daily price data from 15 October 2019 to 17 August 2020 using the canonical vine (C-vine) copula approach. We observed significant changes in the dependence structure, the selection of the pair copula families, and the associated parameter estimates in the tree. In developed markets, during the COVID-19, the dependence of markets shifted from the Netherlands to France while the root node position of Hungary replaced the market of Poland. The frontier markets showed strong dependence signs with Mauritius before COVID-19 and Slovenia during the outbreak. Our findings are of interest to regulators and practitioners, particularly in monitoring the value at risk of portfolios and adopting appropriate strategies in light of the varying dynamics of stock markets during extreme events, such as COVID-19.

  • Ahmad, Muhammad Farooq , Saqib Aziz, and Michael Dowling (2022) Does target country cultural orientation influence M&A? » British Journal of Management, Volume 33 Issue 2, April 2022 pp 906-938

We examine whether the cultural orientation of target firms influences the outcomes of international mergers and acquisitions (M&As). Prior research shows that the national culture of the acquiring firm country influences M&As, as well as the distance between the acquiring and target country cultures. Not previously studied from a cultural perspective of M&As has been the target country culture, despite estimates that about 40% of M&As are target-initiated. Our focus is on target firm cultural orientation, including how cultural orientation affects the likelihood of, and returns from, M&As. Our testing applies three cultural orientation factors (results, tradition and people orientation) extracted from a GLOBE cultural framework to a dataset of firm-level M&A data across 39 countries, in 1990–2016. We find that firms from cultures with a results orientation are less likely to become M&A targets and also experience higher cumulative abnormal returns if acquired, while firms from countries with cultures with a tradition orientation or a people orientation are more likely to become targets but experience lower cumulative abnormal returns if acquired. These results are robust to a comprehensive range of robustness tests. Our findings suggest that understanding the cultural orientation of target firms is important to understanding M&A outcomes.

  • Gao, S., Bagnarosa, G., Dowling, M. Matkovskyy, R. & Tawil, D. (2022) Price transmission in European fish markets. Applied Economics 54:19, 2194-2213

We investigate price transmission in European fisheries markets. To start, we identify clusters of fish species both cross-regionally and within countries. A major issue in the clustering exercise is missing data due to reporting issues and seasonality in landed fish catches. To handle this we implement k-POD clustering which unlike traditional k-means clustering is able to account for missing data in clustering. Next, we move on to our primary goal of investigating price transmission through modelling price volatility spillovers. A missing value VAR framework is applied to identify directional spillovers among fish prices within clusters. We show that the directional volatility spillover effect is more prominent within each country for different species clusters than that for species cross-regionally. This suggests price transmission within localized markets for fish, rather than cross-regional markets for individual species. Although there are some neighbour country effects and some species that appear to be priced cross-regionally. Our  study is the first to explore these multiple fish pricing dynamics, particularly taking account of the important issue of missing data which is a notable feature of fish pricing data

This study examines the role of hybrid products employed in companies’ innovation strategy within three American industrial sectors: tires, typewriters and photography cameras. Design/methodology/approach – The authors selected historical cases that enabled us to present the role of hybrid products in periods of discontinuous change. Different sources are employed in this study: papers, books, cases, working papers, videos, manuals and product catalogues, companies’ annual reports, company websites, advertising, collectors’ websites and museums, in addition to press and other media reports. Findings – The authors’ historical case analysis points to two forms of hybrid products. (1) Exploitation hybrid, which incorporates significant elements from the existing dominant design and aims at extending the revenue-generating opportunities of the existing products. (2) Exploration-hybrid, which works as an offensive strategy, as the firm uses the exploration-hybrid to promote a gradual and controlled adoption of new technology by reducing risks and the cost of change for the customer. Research limitations/implications – The authors’ proposed definitions strengthen the idea that hybrids are not only a reflection of organizational inertia (exploitation-hybrid). Hybrids can also mean a more proactive stance in the strategy of developing and adopting new technology (exploration-hybrid). Originality/value – This study acknowledged hybrid products as a learning instrument that materialized the organizational ambidexterity, favoring at the same time exploitation, generally attributed to organizational inertia, and the exploration of new segments of customers or the use of new technologies.

Through exploratory interviews with Brazilian franchisees, reasoning and process of how franchisees develop their multibrand, multisystem and multirole portfolio is elucidated. Franchisees in Brazil with ownership stakes in more than one brand/system aim to keep units within their monitoring range, while diversifying to mitigate risk of their portfolios. Brazilian franchisees have created an active marketplace in which franchises are traded akin to commodities and franchises serve as schools or entrepreneurial “internships” for franchisees who seek new skills. A new framework of laddered diversification options in franchising is developed.

This paper examines differences in bank efficiency between banks affiliated with single bank holding companies and those affiliated with multi-bank holding companies by applying a fuzzy multi-objective two-stage data envelopment analysis technique. Using a sample of U.S. commercial banks covering 1994–2018, the results show that banks affiliated with multi-bank holding companies are more efficient than those affiliated with single-bank holding companies, suggesting that the former takes advantage of their parents’ resources to enhance their efficiency, consistent with the internal capital market theory. They also show that banks with a powerful CEO exhibit lower efficiency than others. Moreover, there is an inverted U shape relationship between multi-bank holding company structure and bank efficiency, suggesting the presence of an optimal number of multi-bank holding subsidiaries that maximizes efficiency.

This paper analyzes the influence of small and medium-sized enterprises’ (SMEs) entrepreneurial orientation (EO) on its capacity to quickly introduce new products to the market (namely, speed to market). Specifically, we suggest that firms will exhibit greater speed to market when displaying either low or high levels of EO. We also suggest that the EO – speed to market relationship will be contingent on firms’ ambidexterity, or its capacity to simultaneously embrace exploratory and exploitative strategies. To test our hypotheses, we collected survey data from 384 SMEs belonging to four sectors in Spain: biotechnology, ceramic tiles, toys and footwear. Our findings confirm the existence of a U-shaped connection between EO and speed to market, and evidence that this curvilinear relationship is accentuated when SMEs exhibit greater ambidexterity.

This paper examines differences in bank efficiency between banks affiliated with single bank holding companies and those affiliated with multi-bank holding companies by applying a fuzzy multi-objective two-stage data envelopment analysis technique. Using a sample of U.S. commercial banks covering 1994–2018, the results show that banks affiliated with multi-bank holding companies are more efficient than those affiliated with single-bank holding companies, suggesting that the former takes advantage of their parents’ resources to enhance their efficiency, consistent with the internal capital market theory. They also show that banks with a powerful CEO exhibit lower efficiency than others. Moreover, there is an inverted U shape relationship between multi-bank holding company structure and bank efficiency, suggesting the presence of an optimal number of multi-bank holding subsidiaries that maximizes efficiency.

This study aims to analyze the individual and joint effects of institutional support by government and nongovernment institutions on early internationalizing firms’ (EIFs) performance. It also investigated the moderating impact of firm age and size on the institutional support-firms’ export performance relationships. Data were collected from 705 EIFs in the apparel industry of Bangladesh and analyzed with hierarchical regression. The positive influence of institutional support on exporting firms’ financial performance is stronger for the joint effect of government and nongovernment assistance than the individual impact. Firms’ size positively moderates the impact of individual government and nongovernment assistance, while age positively moderates their resource-bundling effect. The findings suggest the necessity of integrating resources from diverse but complementary sources of institutional support for superior export performance. The findings also show the presence of the liability of smallness and liability of newness in the standalone and joint influence of institutional support, respectively. Firms need to bundle resources obtained from the government (unrequited) and nongovernment (reciprocal) institutional support to overcome the liability of smallness they might encounter while availing of support fromonly one source.

COVID-19 household transmissibility remains unclear in Pakistan. To understand the dynamics of Severe Acute Respiratory Syndrome Coronavirus disease epidemiology, this study estimated Secondary Attack Rate (SAR) among household and close contacts of index cases in Pakistan using a statistical transmission model. A retrospective cohort study was conducted using an inclusive contact tracing dataset from the provinces of Punjab and Khyber-Pakhtunkhwa to estimate SAR. We considered the probability of an infected person transmitting the infection to close contacts regardless of residential addresses. This means that close contacts were identified irrespective of their relationship with the index case. We assessed demographic determinants of COVID-19 infectivity and transmissibility. For this purpose based on evolving evidence, and as CDC recommends fully vaccinated people get tested 5–7 days after close contact with a person with suspected or confirmed COVID-19. Therefore we followed the same procedure in the close contacts for secondary infection. During the study period from 15th May 2020 to 15th Jan 2021, a total of 339 (33.9%) index cases were studied from 1000 cases initially notified. Among close contact groups (n = 739), households were identified with an assumed mean incubation period of 8.2+4.3 days and a maximum incubation period of 15 days. SAR estimated here is among the household contacts. 117 secondary cases from 739 household contacts, with SAR 11.1% (95% CI 9.0– 13.6). All together (240) SAR achieved was 32.48% (95% CI; 29.12–37.87) for symptomatic and confirmed cases. The potential risk factors for SAR identified here included; old age group (>45 years of age), male (gender), household members >5, and residency in urban areas and for index cases high age group. Overall local reproductive number (R) based on the observed household contact frequencies for index/primary cases was 0.9 (95% CI 0.47– 1.21) in Khyber Pakhtunkhwa and 1.3 (95% CI 0.73–1.56) in Punjab. SAR estimated here was high especially in the second phase of the COVID-19 pandemic in Pakistan. The results highlight the need to adopt rigorous preventive measures to cut the chain of viral transmission and prevent another wave of COVID-19



  • Maher A.N. Agi, Ashish Kumar Jha (2022) Blockchain technology for supply chain management: An integrated theoretical perspective of organizational adoption. International Journal of Production Economics, Volume 247, May 2022, 108458

Blockchain technology has been growing in importance and acceptability over the past few years. Yet, there is limited empirical research on the organizational and technology specific factors that play a critical role in driving its adoption in the supply chain. The purpose of this paper is to develop a comprehensive framework for blockchain adoption in the supply chain by identifying the enablers and empirically evaluating their interdependencies and impact on adoption. 20 enablers of blockchain adoption in the supply chain are identified using an extensive literature review and theoretical lenses from the Diffusion of Innovation (DOI) theory and the business technology adoption model developed by Iacovou, Benbassat and Dexter (1995). In the confirmatory phase, we employ the Decision-Making Trial and Evaluation Laboratory (DEMATEL) method to extract logic from data collected from 37 French experts about the impact of the enablers and their interdependencies. Our paper extends the multi-theoretic empirical studies to blockchain technology and identifies the enablers of blockchain adoption from technological, organizational, supply chain and external environment perspectives. Regarding the importance of the categories of enablers, we find that the relative advantage of the technology and the external pressure are the most prominent categories of enablers that impact blockchain adoption in the supply chain. Our analysis also shows the important causal role on adoption of the potential of blockchain to reduce transaction cost, the consumer interest in traceability data and the establishment of a regulatory framework for blockchain usage.

This paper investigates whether the Shariah compliance matters in determining investor behaviour in herding across firms in the global energy market. Our sample comprises 2501 globally listed energy equities from 10 April 2019 to 8 April 2020 from the Refinitv Eikon database, which also flags firms as compliant or otherwise with Shariah or Islamic law. Using closing price data for the selected firms, we analyse herding behaviour across the two groups, in addition to various firm and market characteristics such as size, profitability, analyst recommendations about future performance and up and down market days. Our results suggest herding in both Shariah and non-Shariah-compliant energy firms, and on down market days in particular. Cross-sectional tests indicate higher herding in larger and more-profitable Shariah firms, and those with positive analyst forecasts for the future, which is consistent with pressure-driven behaviour to maintain performance. In particular, we find that the COVID-19 pandemic does not significantly alter herding behaviour for the sample firms.

The purpose of this study is to develop an Islamic Banking Index representing the Islamic banking model and to investigate its impact on the performance of Islamic and conventional banks. This study also analyzes the impact of Islamic financial development on bank performance. The authors collected the data from 23 countries for the period from 2010 to 2018 and developed a composite Islamic Banking Index. The authors applied the generalized method of moments on 3,542 bank-year observations for both Islamic and conventional banks to analyze the impact of the Islamic Banking Index on bank performance. The results of the study are robust to time-fixed effects, country-level time-varying factors and endogeneity issues. The authors found that Islamic Banking Index positively contributes to the return on assets (ROAit) of Islamic banks only. This impact becomes highly significant in countries with comparatively higher Islamic financial development. This finding suggests that the Islamic financial development in a country provides a supportive operating environment to Islamic banks and increases their performance. The authors also found that Islamic Banking Index positively contributes to the return on equity (ROEit) of both types of banks. The authors argue that moving away from interest-based products and focusing more on diversified portfolios can boost the performance of both types of banks without increasing their risk levels. To the best of the authors’ knowledge, this is the first study that develops a composite Islamic Banking Index based on differentiating factors of the Islamic banking model and investigates the impact of Islamic Banking Index and Islamic financial development on bank performance.

  • Tanveer Ahsan, Bakr Al-Gamrh, Sultan Sikandar Mirza (2021) Economic policy uncertainty and sustainable financial growth: Does business strategy matter? Finance Research Letters, Volume 46, Part B, May 2022, 102381

Using a data of 975 Chinese non-financial listed firms, this study investigates the impact of firm business strategy on sustainable financial growth during economic policy uncertainty. We use index-based measures of economic policy uncertainty, sustainable financial growth and business strategy and observe that economic policy uncertainty hurts the sustainable financial growth of Chinese firms. However, we find that a defensive business strategy positively moderates the negative impact of policy uncertainty, whereas an analytical business strategy mitigates the negative impact of policy uncertainty on sustainable financial growth. The results of the study provide guidance to corporations regarding strategy formulation to effectively deal with policy uncertainties. Our results are robust to different proxies of policy uncertainty and endogeneity issues.

This study investigates whether waste management, including waste generation and recycling, affects firm performance. Using a panel of 14,601 firm-year observations from 41 countries from 2002 to 2019, we find a significantly negative (positive) relationship between waste generation (recycling) and firm performance. Our findings are robust to alternative measures of waste management and firm performance, sub-sample analysis, and alternative econometric specifications. Further, our results are robust to different identification strategies. Finally, our channel analysis shows that the negative (positive) relationship between waste generation (recycling) and firm performance is stronger in firms offering no environmental, social, and governance (ESG) based compensation. However, the relationship varies with the level of firms’ environmental orientation, and we observe insensitivity of the relationship regardless of firm-level governance quality. Our study presents important policy implications for regulators and firms.

Big data analytics (BDA) and artificial intelligence (AI) may provide both bright and dark sides that may affect user participation in ridesharing. We do not know whether the juxtaposed sides of these IT artefacts influence users’ cognitive appraisals, and if so, to what extent will their participative behaviour be affected. This paper contributes to the IS research by uncovering the interplay between the dark and bright sides of BDA and AI and the underlying mechanisms of cognitive appraisals for user behaviour in ridesharing. We performed two phases of the study using mixed-methods. In the first study, we conduct 21 semi-structured interviews to develop the research model. The second study empirically validated the research model using survey data of 332 passengers. We find that the usage of BDA and AI on ridesharing platforms have a bright side (usefulness, “the good”) but also a dark side (uncertainty and invasion of privacy, “the bad and the ugly”). The bright side generates perceived benefits, and the dark side shape perceived risks in users, which discount the risks from the benefits of using the ridesharing platform. Privacy control exerts a positive effect on the perceived benefits to encourage individuals to use the ridesharing platform

Decision-makers in companies increasingly face unprecedented natural disasters. When business continuity is at risk, managers need a framework to imminently react. A literature review and analysis of survival responses in nature and business case examples of company responses to the Covid-19 pandemic was the approach used. There are direct parallels between the physiological stress response when a living individual perceives a threat to its survival, and the immediate reactions that occur when companies are faced with a disruptive event. This article is meant to be used by decision-makers in companies to better react to disruptive events. While nature-inspired methods have inspired inventions and algorithms, Hans Selye’s general adaptation theory has not been used in parallel with business scenarios. We correlate fundamental organism survival mechanisms with a risk response framework to improve the probability of business survival during external threats.

As perceived by company employees, luxury culture is best understood by collecting and analyzing anonymous genuine current or past employee-generated comments (EGCs) about their experience of specific work culture, without fear of retaliation by using digital platforms. This paper focuses on luxury culture, including organizational culture, founder culture, and country-of-origin culture. It examines the employee perception of organizational culture in the case of L’Oréal, a luxury cosmetics company, by analyzing EGCs collected from a digital platform. This study demonstrates that sentiment analysis methodology is a valuable technique in understanding how employees’ perceptions of luxury companies’ cultures and significantly that changes happening in luxury brands’ dynamic organizational cultures may well be known relatively early by analyzing the EGCs. This study adds a new factor to the luxury organizational culture called “digital culture,” in addition to the previously identified cultural determinants, including collective, emotional, historical, symbolic, dynamic, and diffuse dimensions

  • Duzert, Yann , Cris Carneiro, and Rafael Almeida. Culture of alternative dispute resolution in Brazil: an exploratory study of business mediation from the theory, law and perception of lawyers. Beijing Law Review. Vol 13. (2022): 100

The purpose of this paper is to examine the current Brazilian scenario for resolving queries, the laws enacted and the participation of lawyers, including the studies they undertake in Brazilian law schools. This paper will focus on the extent of an ADR culture in Brazil analyzing the context of ADR’s in Southeastern Brazil (São Paulo, Rio de Janeiro, Espírito Santo and Minas Gerais) after the period of the validity in 2016 of the Brazilian Civil Procedure Code (Law No. 13.105/2015) calling for judicial1 mediation and stimulating ADR in Brazil up to 2017 (the year of data collection). An exploratory research was done. This study also seeks to 1) present the Southeastern Brazil data on the number of mediation sessions in order to identify the growth in the use of this method and 2) check the knowledge of Brazilian lawyers on the topic of ADR’s. A bibliographic and an archival research were carried out followed by three field researches using quantitative methods. The first research was implemented on a total of 621 lawyers who responded through a questionnaire with: two variables focused on individual characteristics of the respondent, five variables on the lawyer’s studies in negotiation/ADR, and ten variables on his/her professional activities. This questionnaire was designed to identify how lawyers actually negotiate and should serve to shatter the myth that adversarial bargaining is more effective and less risky than problem-solving. It is important to mention that some elements were adapted to the Brazilian culture. The second inquiry was conducted on a total of 397 lawsuits forwarded to business mediation in Rio de Janeiro court from 2016 (91 lawsuits) through 2017 (306 lawsuits). The variables of this research were completely different from the lawyers’ questionnaire. In this one, there were 6 variables on the characteristics of lawsuits and 8 variables on the agreement settled. The third study was also done in this court on a total of 270 lawsuits. This sampling was obtained at the center dedicated to the study of the judiciary at Fundação Getulio Vargas (FGV) that is responsible for doing CNJ’s (National Counsel of Justice) reports, such as Supreme in Numbers—this report analyzes the processes in Brazilian Superior Court and Justice in Numbers. The research focused on agreements settled directly by parties without mediation. However, in this group, the data is compiled by sampling. During the study period of this thesis, 2700 lawsuits were initiated. FGV, using the software language MySQL, randomized 270 lawsuits (10%) which were analyzed by the author of this thesis based on the same elements and the previous inquiry. The analysis provided results on how ADR has been developed in Brazil. The possibility for generalizations has been confirmed for both inside and outside the courts. There is a movement for culture change and greater adoption of ADRs in Brazil. However, the paradigm shift has not yet been fully realized. The Brazilian Civil Procedure Code (Law No. 13.105/2015) calling for judicial mediation and stimulating ADR in Brazil increased the number of judicial mediation sessions. Lawyers are not familiar with the adoption of ADR as problem-solving and their acting is not seen as collaborative. This generalized performance measurement can be used in future research and for professional purposes in the ADR environment. The study also presents a comparison of business mediation done inside and outside courts

Medical tourism is a recent term in healthcare logistics referring to travel of patients to receive health services and spending leisure time in a destination country. This transferring of patients leads to access high-quality health services which are cheaper than the original country of patients. During this travel, passengers who are the patients from another country, have this opportunity for complimentary entertainment packages (e.g., pleasure tours) in the aftercare period. As far as we know, the term of medical tourism is rarely studied in healthcare logistics and such services are highly important for developing countries. Such facts motivate us to develop a practical optimization model for the Medical Tour Centers (MTCs) for allocation of patients to hospitals in proper time and creation of memorable aftercare time for them. In this regard, the main aim of the proposed model is to maximize the total profit of MTCs through optimal allocation of patients to hospitals while considering an aftercare tour for the passengers. To make the proposed model more realistic, the optimal residence time in attractive places is simulated by a time-dependent gravity function. To address the uncertainty of medical tourism problem, a scenario-based two-stage stochastic optimization approach is extended to encounter different sources of uncertainty existing in surgical success, medical time, restoration restrictions, and the attraction of tourist places. Another novelty of this work is to propose an innovative hybrid meta-heuristic for large-scale instances, which is a combination of Progressive Hedging Algorithm (PHA) and Genetic Algorithm (GA). The model is analyzed by different test problems for small, medium, and large-scale instances where the hybrid meta-heuristic algorithm could solve them with an average gap of 3.4% in comparison with the commercial solver. The results revealed the importance of tourist opinion and public preferences in medical and pleasure tours, respectively, to improve the economic growth in this sector in developing countries

Recent market studies showed that the demand for organic and local agrifood products is increasing despite their higher prices. The agribusiness actors should therefore rethink the supply chain configuration to cope with new market trends characterized by the rise of the organic segment and the increase of consumers’ preference to more local products. This study focuses on the olive oil sector and proposes a mixed-integer non-linear optimization model for the design of olive oil supply chains while incorporating organic and conventional market segments and considering, for each segment, a supply chain proximity- and price-sensitive demand. The model is developed with the collaboration of olive oil producers in the Mediterranean area. Thanks to this industrial collaboration, we account for real-world practices and constraints and apply the model to a realistic case study. We first linearize the model and show that it can be efficiently solved with commercial optimization softwares. Based on numerical experiments, we derive a series of managerial insights that are applicable to the considered case study, some of them are not intuitive. For instance, we show that an increase in consumers’ preference to more local products may lead the producer to offer products with a more global supply chain. The conventional product variety may be produced with a more local supply chain than the organic (premium) variety. Finally, offering a mix of organic and conventional varieties instead of only one variety would lead to implementing a more local supply chain.

  • Perrigot, R. (2022) Social relationships and communication as key characteristics of social franchising in Africa. International Journal of Retail & Distribution Management, Vol. 50 No. 5, 2022, pp. 619-637

This paper, using a case study on Jibu, a water distribution chain that distributes bottled water in Africa, aims to underline the importance of social relationships and communication within franchise chains operating in the social sector in developing countries and their contribution to the clarification of the concept of social franchising. Design/methodology/approach – The research is based on a case study of Jibu, a water distribution chain composed of 122 franchised units and 2,100 independent retailers. The primary data were gathered through an analysis of in-depth interviews with 67 people (Jibu co-founder, headquarters staff, franchisees, micro-franchisees and customers) in Uganda and Rwanda. Findings – The findings showed that the extent and richness of social relationships and communication existing within the Jibu chain are not limited to top-down and build a feeling of belonging to a family. These social relationships and communication are key characteristics of social franchising. Practical implications – This research can assist franchise experts, franchisors and franchisees to better assess the importance of social relationships and communication in social franchise chains in developing countries and help national and local governments better understand how franchising works in the social sector. Social implications – Franchising is not limited to hotels, restaurants and retail businesses. Franchising can be applied to businesses that have social goals, in addition to profit goals. For example, the Jibu franchise is a relevant and efficient solution to providing the African people with access to drinking water at an affordable resale price. This paper, thus, contributes to increasing the awareness of this franchising phenomenon in social sectors in developing countries and in Africa, in particular. Originality/value – Access to drinking water is an important issue in many developing countries, above all in African countries. Franchised water services are an innovation in terms of a business model in developing countries with micro-treatment plants run by franchisees and small units run by micro-franchisees or retailers, both franchisees and micro-franchisees being local entrepreneurs.

Although franchise chains are increasingly committed to environmental, social, and societal transitions, only a few researchers have focused on Corporate Social Responsibility (CSR) in the specific case of franchising. The aim of our paper is to discuss the specificities and challenges of CSR in franchising, explore how franchisors report on their sustainable practices, and emphasize subsequent directions for future research. In order to do so, we focus on the Corporate Social Disclosure (CSD) practices of twenty-two retail and service franchisors operating in the French market where regulations of non-financial information disclosures exist for large companies. Our findings show that these franchisors disclose rich and diversified information about their CSR activities. However, franchisors’ disclosures can vary significantly, especially depending on their chain size and whether they are subject to reporting regulations. Our research contributes to the literature on CSR in franchise chains, as well as the practice.

This paper investigates the green technology development (GTD) problem of a capital-constrained manufacturing entrepreneur who seeks financial support from external and internal multi-sided platforms (MSPs). Following the government’s environmental policies, MSPs (i.e., outsourcing and insourcing alternatives) determine their strategies and offer platform-driven solutions to the manufacturing entrepreneur pursuing green innovation. Using benchmark models, we first analyze decisions made by the manufacturing entrepreneur and the MSP under the deregulated scenarios. We then develop a three-level game-theoretical model and sequentially characterize the decision-making behavior of players under three platform power structures. The model outcomes are compared by considering the government’s policymaking approach and platforms’ power structure. Results reveal that, when coupled with appropriately designed trade-credit and revenue-sharing mechanisms and the government’s innovation-based social welfare approach, the internal MSP system always outperforms the external alternative. Our study demonstrates that a win-win agreement among GTD players can only be achieved if the MSPs take the balance of power and remain committed to empowering the initiated sustainable ecosystem. In power struggle scenarios, however, GTD players prioritize the internal MSP over the external MSP. To fulfill the GTD goals, players are encouraged to use their structural and legislative power and adjust their strategies, investment decisions, and power preferences accordingly.

This research adopts a consumer focus in examining the impact of perceived legitimacy of sharing economy platforms on attitude and behavioural intention in the accommodation sector. By investigating tourist adoption of sharing economy platforms from a legitimacy perspective, this research differs from past studies which focused on characteristics of new services to predict adoption. Results show that (1) tourists evaluate legitimacy through comparisons with traditional offers in the accommodation sector rather than with other sharing economy offers, (2) lack of legitimacy has a negative effect on guest behavioural intentions and (3) this effect is moderated by relativism. Even though sharing economy platforms’ commercial success may imply that they are enjoying a high level of legitimacy in the eyes of tourists, our results suggest that tourists act as societal actors and that the legitimacy issues raised by the sharing economy are relevant to them and inform their decisions.

We identify the core topics of research applying machine learning to finance. We use a probabilistic topic modeling approach to make sense of this diverse body of research spanning across multiple disciplines. Through a latent Dirichlet allocation topic modeling technique, we extract 15 coherent research topics that are the focus of 5942 academic studies from 1990 to 2020. We find that these topics can be grouped into four categories: Priceforecasting techniques, financial markets analysis, risk forecasting and financial perspectives. We first describe and structure these topics and then further show how the topic focus has evolved over the last three decades. A notable trend we find is the emergence of text‐based machine learning, for example, for sentiment analysis, in recent years. Our study thus provides a structured topography for finance researchers seeking to integrate machine learning research approaches in their exploration of finance phenomena. We also showcase the benefits to finance researchers of the method of probabilistic modeling of topics for deep comprehension of a body of literature.

  • Macpherson A, Breslin D, Akinci C. (2022) Organizational Learning From Hidden Improvisation. Organization Studies. Vol. 43(6) 861–883

Research has identified improvisation as a creative and open activity that can be harnessed to encourage innovation and learning within the organization. In this paper, we present improvisation as a covert phenomenon, occurring in a climate of mistrust and fear of censure, and disconnected with wider organizational learning. Drawing on qualitative evidence of a Fire Service in the United Kingdom, we explore hidden improvisation, and identify the conditions and processes that can connect these local deviations to wider processes of learning. We show that while most improvisations remain hidden and contained to avoid wider scrutiny, certain conditions of frequency, connectedness and scale escalate events to become more visible to supervisors and managers. The learning outcomes from these visible improvisations will then depend on management’s interpretation, evaluation and translation of improvising behaviours. Dependent on prior relationships of trust and credibility, middle management perform a key brokering role in this process, connecting previously hidden improvisation to wider organizational systems and structures

  • Clarke, R., Richter, A. W., & Kilduff, M. (2022). One tie to capture advice and friendship: Leader multiplex centrality effects on team performance change. Journal of Applied Psychology. 107(6), 968–986

Because leaders’ authority is often insufficient to change team performance, formal team leaders seek informal influence through the occupation of central positions in social networks. Prior research focuses on leader centrality involving simplex ties, that is, either friendship or advice, to the neglect of multiplex ties that involve the overlap of friendship and advice. Friendship and advice ties offer different but complementary resources, so leader centrality in one but not the other network limits leader influence. We provide theory and evidence concerning how leader multiplex centrality affects team performance improvement, particularly if leaders are embedded in team social contexts with sparse friendship and numerous adversarial ties. The research context involved 84 ongoing public university service teams headed by formal leaders. Our results show the importance of leader multiplex centrality relative to leader simplex centrality. First, leader multiplex centrality predicted team performance change over a 2-year period more strongly than leader centrality in either the advice or the friendship team network. Second, leader multiplex centrality positively predicted team performance change for teams featuring dense adversarial networks or sparse friendship networks. It is not sufficient, therefore, for leaders to be either liked or regarded as expert. It is the integration of both advice and friendship in one tie between the leader and followers that facilitates performance change.

We investigate the impact of acquiring similar or complementary technologies on the innovation performance of Chinese multinationals’ strategic asset-seeking M&As in the EU, and whether such impact is contingent upon firm-level and region-level technological gaps. Results show that technological complementarity enhances Chinese multinationals’ innovation performance. Firm-level technological gaps have a positive moderating effect for both complementary and similar technologies. Region-level gaps enhance innovation when Chinese firms acquire similar technologies, but they undermine the positive impact of technological complementarity on innovation performance. We advance understanding of Chinese MNEs’ learning scope and strategic intents in their strategic asset-seeking M&As.

This study addresses one of the most challenging issues in designing a sustainable and efficient ride-sharing service. This paper uses an extensive computational study to quantify the behavior of carpooling in customized bus routing problems. This mechanism allows organizations to draw on the potential of their employees’ private cars to provide convenient alternative rides for other employees, thereby reducing air pollution and greenhouse gas emissions as well as increasing overall satisfaction with the transportation system offered. The objective functions minimize: (i) total transportation costs and incentives paid to drivers of private cars, (ii) dissatisfaction as determined by staff walking distance, travel time, and delays in arriving at work, and (iii) total carbon emissions generated by commuting. We propose a resolution algorithm based on Pareto Strength Ant Colony Optimization (PSACO) as an effective meta-heuristic method for solving the multi-objective mathematical model and compare it with the results obtained by an exact method. The effectiveness and applicability of the proposed problem have been evaluated by performing computational experiments on a real case study in Paris using a number of comparative metrics with appropriate assumptions. Different parameters affecting the performance of the algorithm are also investigated. The concluding section presents a comparison of the results achieved.

Governments all over the world adopted different forms of progressive carbon taxation strategies (for example concave, convex and linear for respectively Swedish, French, and Canadian government). These progressive strategies provide companies with different degrees of flexibility to adapt their decisions to the new environmental regulations and reduce their carbon emissions without compromising their profit. However, no existing work has compared the impact of each progressive legislation on the optimal decisions of the supply chain, its profit, and its environmental performances. In this paper, we contribute to the literature by developing four multi-period technology selection models under different forms of progressive carbon taxes. We analytically determine the optimal strategic investment timing decision under each taxation strategy. We then develop a carbon tax assessment method using multi-criteria analysis techniques to compare the efficiency of each carbon taxation form in reducing carbon emission and maximising the Supply Chain (SC) profit. We prove that the earliest green investment decision and the decision of not investing in green depend on the target carbon tax rather than the taxation form. We show that government decision about the suitable taxation form should be based on the performance of the available green technologies.

In this perspective piece, we aim to broaden understanding of business model innovation (BMI) by expanding and deepening extant theoretical dimensions and positions in the literature. While a significant amount of research has been carried out on the phenomenon of BMI, the current theory does not fully capture the broad diversity and inherent implications of the various approaches taken. We address this lack of common ground by developing an organizing framework for BMI research. To do so, we first delineate the business model (BM) concept’s multifaceted properties that provide the foundation for theorizing BMI. Using topical identification, we then situate and substantiate a range of theoretical lenses within strategy, innovation, and entrepreneurship, as three central research axes informing studies on BMI. By revealing the relevant research perspectives, theoretical lenses, and positioning choices in the framework, our work expands and further details the conceptualization of BMI and provides orientation for future studies in the field.

Using a dataset of Chinese listed companies from 2009 to 2018, this study empirically examines the relationship between a company’s institutional environment, the ultimate controller’s characteristics and its level of corporate social responsibility (CSR) disclosure in China. The results show that Chinese companies operating in better institutional environments have higher CSR disclosure. Moreover, the type of the ultimate controller of a company is significantly related to the level of CSR disclosure, which is higher in state-controlled companies than in nonstate-controlled companies. The results are robust to different proxies of CSR disclosure

This study examines how debtholders perceive accounting information quality of firms with audit committee members who are also on the remuneration committee, and whether strong CEO power enhances or undermines the governance role of overlapping committees. Using 841 observations of Malaysian firms over the period 2013–2015, we find that firms with overlapping audit and remuneration committees are perceived by debtholders to be transparent and of lower operating risk and, consequently, be associated with lower cost of debt. We also find that the beneficial effect of the presence of overlapping committees is weakened by the level of CEO power. Our results are robust to concerns of endogeneity and alternative measurers of the key variables. This study is timely in light of recently increasing call for the broadening of audit committee members’ understanding of business strategies, risks and incentives provided by firms’ executive compensation structures. Our study also contributes to the ongoing debate surrounding CEO power by suggesting that debtholders perceive potent CEO power as detrimental to their investments and thus charge higher interest rates from firms with powerful CEOs and overlapping directors

The literature on Mergers and Acquisitions (M&A), cultural differences between organizations have frequently been identified as one of the main challenges in the process of post-merger integration (PMI). Existing research has explored a broad variety of cultural differences in perceptions, such as those relating to expectations, norms, values and beliefs within the respective organizations, and how these affect the process and success of PMI. However, less attention has been paid to the relevance of the macro-societal context to PMI. The ambition of this article is, therefore, to advance our understanding of how macro-level societal factors define organizational cultures and affect the success of PMI. We draw on social systems theory as devised by Niklas Luhmann, assuming that organizations are always embedded in the macro-level societal context of distinctive realms of social reality—such as the economy, politics, religion and the arts—that make up the so-called “function systems”. Looking at the case of the integration of a Brazilian technology start-up into a market-leading corporation, we analyze the dominant orientations towards these function systems, and the changes in these orientations over time. The results suggest that differences in organizational culture in PMI can be partly explained by differences in orientations to the function systems. Moreover, forcing dramatic changes of orientations towards the function systems within a merged entity can severely damage its raison d’etre in the first place, potentially leading to, in some sense, an account of “culture murder”. This article is unique in demonstrating that organizations are multifunctional systems whose culture is defined by the highly specific and potentially varying degrees of importance they place on individual function systems and that knowledge or neglect of these functional profiles may seriously affect the success of post-merger integration. Against this backdrop, the article presents a multifunctional profiling method that may easily translate into PMI management tools

We document short-run changes in websites and the web technology industry with the introduction of the European General Data Protection Regulation (GDPR).We follow more than 110,000 websites and their third-party HTTP requests for 12 months before and 6 months after the GDPR became effective and show that websites substantially reduced their interactions with web technology providers. Importantly, this also holds for websites not legally bound by the GDPR. These changes are especially pronounced among less popular websites and regarding the collection of personal data. We document an increase in market concentration in web technology services after the introduction of the GDPR: Although all firms suffer losses, the largest vendor—Google—loses relatively less and significantly increases market share in important markets such as advertising and analytics. Our findings contribute to the discussion on how regulating privacy, artificial intelligence and other areas of data governance relate to data minimization, regulatory competition, and market structure

A key premise in innovation literature suggests that individuals enabling contact between pairs of otherwise disconnected others (i.e., holding open triads) are more innovative, as they benefit from more opportunities for knowledge recombination. Such benefits also come with a cost, as conducting innovative action from open triads requires finding common ground to coordinate and integrate disparate knowledge and efforts from unconnected others. However, it is yet unclear which specific open triadic structures offer the greatest net value to facilitate individual innovativeness. We contribute to this debate by going beyond a homogeneous conceptualization of open triads, examining the relation between different brokerage roles and individual innovativeness. We theorize that some roles are more balanced than others in terms of access to knowledge novelty and integration costs. Specifically, we find that balanced open triads (gatekeepers and itinerant roles) are crucial to facilitate individual innovativeness, as compared to unbalanced open triads (coordinator and liaison roles). We also propose that brokers obtain the greatest innovation benefits from balanced open triads when they are embedded in institutional settings that are distant from knowledge applicability. We test our ideas through a large-scale study of 1,010 biomedical scientists

Taking an inductive approach, this paper explores a key question with respect to tourists’ meaning creation: What is the role of servicescapes in the development of place meanings for tourists? The research is situated in place and appropriation theory and leverages a large two-phase qualitative study on tourists’ restaurant experiences in Brittany, an important tourism destination in the North-West of France. Analysis of the narrative data uncovers four dimensions of restaurant servicescapes that contribute to place meaning. These are: The Interior Environment; The Service Offer; The Social Environment, and the Restaurant Exterior. Furthermore, the research provides insights into the ways tourists connect servicescapes to destinations through physical and sensorial immersion, investigation, and learning. This research can help practioners in creating more meaningful holiday experiences and in branding and promoting tourism destinations. It opens the way for the exploration of the role other tourism services in the development of meaningful tourism experiences.

Climate change discourse integrates 3Ps – people, planet, and profit. However, we do not find any empirical study that integrates 3Ps. Therefore, using a large global panel dataset from 46 countries, this study intends to fill this gap by providing empirical evidence about investors’ value proposition of corporate climate performance in different cultural environments. The results show that Hofstede’s cultural dimensions affect corporate climate performance and its market pricing. We find that in cultures with high power distance, low individualism, high masculinity, high uncertainty avoidance, high long-term orientation, and high restraint, the investors generally penalize the firms disclosing higher environmental performance. Strangely enough, corporate waste production is universally value irrelevant. Our results indicate some policy implications.

This study explores a new methodology called community-aided brand concept map (CA-BCM) for eliciting brand association networks using data collected from technology-enabled online communities. NVivo software is used to qualitatively code these data to 1) uncover how users associate themselves with a brand and 2) use content analysis to quantify each of these associations, leading to the elicitation of a comprehensive network of brand associations and their relationships. Using the example of a movie brand, the new tool CA-BCM effectively uncovers 1) the core, secondary, and tertiary brand associations and 2) classifies the brand associations into strong, favorable, and unique associations. Finally, 3) using these brand association classification data and the brand awareness level, customer brand equity is measured. Pearson correlation is used to provide external validity to the CA-BCM technique, which shows a significant and positive relationship between customer brand equity and market performance. The implications and limitations of this study are presented

To promote manufacturing transformation and upgrading, this paper proposes a comprehensive analytical framework for manufacturing development from an industrial network perspective. We explore the organizational structure of the manufacturing association network based on the industrial network analysis technique and the modern network analysis technique. A new data envelopment analysis (DEA) model, which considers the interrelated and interactive characteristics of various sectors, is used to evaluate the static and dynamic performance of manufacturing sectors combining the Malmquist productivity index (MLI). We adopt this framework to analyze the development of 18 manufacturing sectors in Hubei Province, China, during the 2012–2017 period. Key development sectors play a critical role in the stability and development of the manufacturing system, yet their performance did not show significant improvement during this timeframe. During the implementation of the Made in China 2025 strategy, most sectors followed the transformation path by enhancing technological strength first and technological application capabilities later. The manufacturing industry in Hubei Province suffers from insufficient informatization construction and slow productivity improvement.

This paper aims to test the impact of negotiation power between auditors and audited companies, in relation to audit fees. The study found that there is a significant positive relationship between auditors’ power of negotiation and the audit fees. In addition, it found that there is a significant negative relationship between the size of the audited companies, their negotiating power and the audit fees. These findings indicate that when companies negotiate with Big4 audit firms, their bargaining power does not have a significant effect on the audit fees. Nevertheless, if the auditor is not one of the Big4, there is a significantly negative relationship between the company’s bargaining power and audit fees. The relationship therefore changes according to the size of a company. If a company is large, there will be a negative relationship with the audit fees. However, if it is a small company, the relationship is not significant.

A delivery mix that includes delivery from stock and drop-shipping is of interest to many internet re- tailers. We consider a retailer serving a time- and price-sensitive market with two substitutable products that differ in the guaranteed delivery time and price, an express product (delivered from the stock) and a regular product (drop-shipped). In case of stockout, customers may switch from the express product to the regular product. We study how to differentiate the products in terms of delivery times and prices and how to determine the stock level to maximize the retailer’s expected profit while satisfying ser- vice constraints. We solve different variants of the problem and derive insights into the optimal retailer’s strategy. In addition, we study the impact of stockout-based substitution. This paper is the first to investigate time- and price-based differentiation along with inventory decisions for a retailer who relies on a hybrid distribution to satisfy a time- and price-sensitive demand subject to stockout-based substitution. When prices and stock are fixed, in addition to minimum and maximum time differentiations, a medium differentiation strategy may be optimal but depends on the stock level. When only prices are fixed, there exists a price differentiation limit below which a minimum time differentiation is optimal, and above which only the express product should be offered. For the general model, numerical experiments show that a higher stockout-based substitution leads to greater time differentiation (which is consistent with the results of previous models) and more stock. However, this would not impact the price differentiation

The cognitive perspective in entrepreneurship research has predominantly evolved around the static conceptions of cognition at the level of individual reasoning. Recently, the emerging stream of situated entrepreneurial cognition asserts that the environment substantially influences the inherent knowledge structures of entrepreneurial reasoning. It claims that the context indoctrinates the perceptions and beliefs underlying decision making, thus authoring entrepreneurial cognition to derive from the recursive interaction between the mind and the respective environment. Drawing on this perspective, this article follows a narrative approach investigating the unfolding dynamics between the entrepreneurial cognition and contextual factors in a business model design. Using textual accounts from 34 episodic interviews with entrepreneurs from corporate entrepreneurship initiatives, we applied a constant comparative method identifying main themes in the data. Our findings show that entrepreneurial cognition is embedded, grounded, and distributed. We provide evidence that the situated entrepreneurial cognition results from the recursive interplay of material objects, bodily interactions, and agents spanning a social system. Our findings suggest that the unilateral consideration of authored cognitive systems falls short in capturing the holistic nature of entrepreneurial cognition. Thus, our findings further empirically ground situated entrepreneurial cognition by placing the entrepreneur at the nexus of individual and context. Finally, this article reveals the business model as a central boundary object connecting and focalizing a variety of influences on the situated entrepreneurial cognition in its social context.

This study examines an important yet underexplored aspect of firms’ sustainability practices, i.e., waste management, in order to analyze its impact on financial performance. Although the extant literature has focused on various aspects of sustainability, the impact of waste management, which has disastrous consequences for the climate and firm performance, remains largely unexplored. Thus, using the 2002–2019 data of listed firms from 41 countries, we found a significantly negative (positive) relationship between waste generation (recycling) and financial performance. Our findings are robust to alternative variables, sub-sample analysis, and identification strategies. Moreover, a channel analysis showed that this relationship is influenced by operating costs, ESG performance-based compensation, industry nature, the Paris agreement on climate change, and the global financial crisis. Overall, the findings suggest that environmental initiatives are beneficial for firms and present important policy implications for regulators and firms.

This study uses the data of A-share listed family firms during the period 2010-18 and employs multiple regression analysis to verify the role of family control and working capital strategy for corporate risk-taking in China. This study also explores the regulatory role of family control in the relationship between working capital strategy and corporate risk-taking of Chinese listed family firms. Results show that greater family control encourages risk-taking behavior in Chinese firms whereas conservative working capital strategy diminishes corporate risk-taking. The results also suggest a regulatory role for family control on the effects of working capital strategy for family firms’ risk-taking behavior. Strong family control weakens the negative association between working capital conservatism and corporate risk-taking. This study’s findings may help managers of family firms to adjust risk-taking behavior in response to changing working capital strategy. The results are robust to different measures of corporate risk-taking and working capital strategy.

This study investigates self-governance within business-to-business (B2B) in the digital knowledge economy. To do so, we elicit the engagement of healthcare professionals (HCPs) and medical science liaisons (MSLs) with “for-profit social media technology” (FPSMT) in e-detailing. Using data from 23 in-depth interviews with HCPs (physicians and pharmacists) and MSLs in Thailand, we show that e-detailing fosters self-governance as a practice. The data identify how FPSMT, as privatized social media managed by large firms, represents a tool for self-governance that is articulated by expert professionals along three cognitive frames: aspiration, regulation, and responsibilisation. Through FPSMT, professionals in highly regulated B2B ecosystems engage in self-governance practice to develop pooled views that are influenced by personal and collective rules. The perspective on self-governance as a practice that is offered allows to understand how B2B network governance rely on professionals’ engagement to foster aspirations for the collective agenda, beyond the narrow pursuit of sales’ objectives.

This study addresses one of the most challenging issues in designing a sustainable and efficient ride-sharing service. This paper uses an extensive computational study to quantify the behavior of carpooling in customized bus routing problems. This mechanism allows organizations to draw on the potential of their employees’ private cars to provide convenient alternative rides for other employees, thereby reducing air pollution and greenhouse gas emissions as well as increasing overall satisfaction with the transportation system offered. The objective functions minimize: (i) total transportation costs and incentives paid to drivers of private cars, (ii) dissatisfaction as determined by staff walking distance, travel time, and delays in arriving at work, and (iii) total carbon emissions generated by commuting. We propose a resolution algorithm based on Pareto Strength Ant Colony Optimization (PSACO) as an effective meta-heuristic method for solving the multi-objective mathematical model and compare it with the results obtained by an exact method. The effectiveness and applicability of the proposed problem have been evaluated by performing computational experiments on a real case study in Paris using a number of comparative metrics with appropriate assumptions. Different parameters affecting the performance of the algorithm are also investigated. The concluding section presents a comparison of the results achieved. The test outcomes confirm that the formulation and the solution methods can be useful references for practice. The insights obtained from the research could provide the basis for designing incentive schemes and information campaigns aimed at making ride-sharing systems more successful and improving their performance

In this paper, we study the gains and losses incurred during the COVID‐19 pandemic. We distinguish between the effects of the pandemic and those of the health measures implemented to reduce the death toll, notably “the lockdown.” Our theoretical model is focused on within‐sector firm heterogeneity and involves imperfect competition in a partial equilibrium setting. A comparison between the gains and losses triggered by both the pandemic and the lockdown indicates that an excess profits tax imposed on the “winners” could partly compensate the “losers” of the same sector.

International business theory suggests that multinational enterprises (MNEs) seek to internalize resources embedded in local firms to complement their own through inter-organisational relationships, yet little is known about whether and how these business linkages differ between foreign (F)MNEs and domestic (D)MNEs. This paper aims to explore the linkage differential between DMNEs and FMNEs operating in the same single country contexts and to examine whether foreignness, regional origin and technological capability make a difference. This study is based on a unique firm-level data set of 292 MNEs located in five advanced, small open economies (SMOPECs). This study analyses the benefit received – in the form of technical and organisational resources and knowledge – by DMNEs and FMNEs via backward, forward and collaborative linkages with local business partners. Our research finds FMNEs benefit less from linkages than DMNEs; and FMNEs originating from outside the region especially so. However,  the results also show technological capability mitigates this difference and is thus a game changer for FMNEs from outside the region. This paper differentiates between  FMNEs and DMNEs in their propensity to benefit from resources received from different local partners and explores the influence of regional origin and technological capability. Despite the advanced and internationally oriented nature of SMOPECs, DMNEs still gain more benefit, suggesting either liabilities of foreignness and outsidership persist, or FMNEs do not desire, need or nurture local linkages.

This study examines the role of emotions and empowerment in the destigmatisation of disability. We draw on 12 in-depth interviews with professional disabled athletes and a netnography study of 221 YouTube comments from consumers of disability sport advertising. The findings show that both athletes and consumers share their own emotions or report on their perception of others’ emotions to mutually empower themselves and each other, which reduces stigma related to disability. By integrating the literatures on stigma, emotions and empowerment, we reveal how consumers of advertising contribute to the destigmatisation of others’ devalued social identities. Theoretical and practical implications of the findings related to advertising and inclusion are discussed.

A detailed conceptualization of how service experiences are transformed into a memory and the circumstances surrounding a memorable experience is not available in the customer experience literature. This paper aims to address this gap using a multi-dimensional framework (memoryscape) to explain memory processes for service experiences. The paper integrates psychology research, and particularly autobiographical memory, within customer experience management. The paper proposes a comprehensive, multi-dimensional framework (memoryscape) of memory and highlights managerial implications. Marketers have yet to fully understand the role of memory in service experience consumption. In today’s service-dominant economy, understanding more about the memoryscape should be a managerial and research priority. The authors present four managerial priorities for managing customer experience memories. The authors assimilate theories and empirical research in psychology, particularly autobiographical memory, to propose an integrated conceptual framework of the service memory process (memoryscape), to provide insights for managers looking to create memorable customer experiences.

Despite the existence of a rich literature on Production Routing Problem (PRP), the lack of investigations on the workforce planning, and its impact on costs and productivity of the organisation caught our attention. This paper aims to fill this gap by designing a novel framework to integrate inventory, production, distribution, routing, and workforce planning decisions simultaneously. Because of the potential long distances between the main plant and the retailers spread throughout the country and also the perishability nature of the products, considering travelling time uncertainty for delivering products is necessary to have feasible decisions. The application of the proposed approach is investigated by being inspired from a supply chain structure from a knowledge-based company. We derive managerial insights on the benefit of an integrated decision. Besides, given the size and complexity of the proposed problem, we were challenged by exactly solving it in a reasonable time. We succeeded to reach this target by designing an innovative hybrid algorithm. Computational experiments on several numerical examples applied on both the studied real case and on PRP literature instances reveal the effectiveness and efficiency of our new hybrid method and permits to derive interesting managerial insights on the joint decisions.

Researchers often combine longitudinal panel data analysis with tests of interactions (i.e., moderation). A popular example is the cross-lagged panel model (CLPM). However, interaction tests in CLPMs and related models require caution because stable (i.e., between-level, B) and dynamic (i.e., within-level, W) sources of variation are present in longitudinal data, which can conflate estimates of interaction effects. We address this by integrating literature on CLPMs, multilevel moderation, and latent interactions. Distinguishing stable B and dynamic W parts, we describe three types of interactions that are of interest to researchers: 1) purely dynamic or WxW; 2) cross-level or BxW; and 3) purely stable or BxB. We demonstrate estimating latent interaction effects in a CLPM using a Bayesian SEM in Mplus to apply relationships among work-family conflict and job satisfaction, using gender as a stable B variable. We support our approach via simulations, demonstrating that our proposed CLPM approach is superior to a traditional CLPMs that conflate B and W sources of variation.We describe higher-order nonlinearities as a possible extension, and we discuss limitations and future research direction.

To commemorate 40 years since the founding of the Journal of Business Ethics, the editors in chief of the journal have invited the editors to provide commentaries on the future of business ethics. This essay comprises a selection of commentaries aimed at creating dialogue around the theme Business versus Ethics? (inspired by the title of the commentary by Jeffrey Harrison). The authors of these commentaries seek to transcend the age-old separation fallacy (Freeman in Bus Ethics Q 4(4):409–421, 1994) that juxtaposes business and ethics/society, posing a forced choice or trade off. Providing a contemporary take on the classical question “if it’s legal is it ethical?”, David Hess explores the role of the law in promoting or hindering stakeholder oriented purpose and governance structure. Jeffrey Harrison encourages scholars to move beyond the presupposition that businesses are either strategic or ethical and explore important questions at the intersection of strategy and ethics. The proposition that business models might be inherently ethical or inherently unethical in their design is developed by Sheila Killian, who examines business systems, their morality, and who they serve. However, the conundrum that entrepreneurs are either lauded for their self-belief and risk-taking, or loathed for their self-belief and risk-taking, is discussed by M. Tina Dacin and Julia Roloff using the metaphor of taboos and totems. These commentaries seek to explore positions that advocate multiplicity and tensions in which business ethics is not either/or but both.

While extending the scarce literature on determinants of corporate social responsibility (CSR) decoupling, we examine the impact of CEO power on CSR decoupling. Using panel data of US firms for 2002–2017, we find that CEO power increases CSR decoupling. Our results remain consistent after controlling for the endogeneity problem. Aligned with the managerial power theory, our results suggest that firms with powerful CEOs are more likely to manage CSR performance through decoupling.

  • Nagula, P.K., Alexakis, C. (2022) A Novel Machine Learning Approach for Predicting the NIFTY50 Index in India. International Advances in Economic Research  Volume 28, issue 3-4, pp 155–170

Over the past decade, extensive research on stock market prediction using machine learning models has been conducted. In this framework, different approaches for data  standardisation methods have been used for financial time series analysis and to assess the impact of data standardisation on the final prediction outcome. The paper uses the feature-level optimal rolling-window batch data standardisation method to improve the machine learning model’s predictive power significantly. Along with the standardisation method, the paper explores the performance of the automated feature interactions learner (Deep Cross Networks) effect on a plethora of technical indicators aiming at predicting the movements of the NIFTY50 index in India, as these predicted changes are reflected in options contracts. Feature-level optimal rolling window data standardisation can identify the optimal window of time such that the correlation between features and the response variable is maximized, with most features correlating at 0.7. In the experiment, 48% of important technical indicators negatively correlated with the response variable. The Deep Cross Network regression model combined with the optimal rolling window batch data standardisation method outperformed all other model configurations at weekly and monthly data frequency. It achieved a directional hit rate of 69.52% (weekly) and 79.17% (monthly) and root mean square error of 2.82 (weekly) and 5.01 (monthly), generating a profit 5.5 times (weekly) and 2.85 times (monthly) greater than the benchmark buy-and-hold strategy providing opposing evidence to the sub-martingale model.

This study empirically investigates the role of product market competition and mature-stage firm life cycle on the relation between corporate social responsibility (CSR) and market performance in an emerging market context – Malaysia. The authors construct a comprehensive CSR index toward the economy, environment and society (EES) and apply both Ordinary Least Squares (OLS) and Two-Stage Least Squares (2SLS) instrumental variables (IV) approaches to test the hypotheses of the study. The authors find that EES-based CSR generally enhances firms’ market performance; however, the level of product market competition undermines the market performance of socially and economically responsible firms. In addition, the study results indicate that mature-stage firm life cycle with more involvement in CSR activities shows better market performance. However, the endogeneity check of CSR suggests that both CSR and mature-stage firms are mutually exclusive in influencing market performance. The study findings are robust to alternative measures and different identifications of high and low default risk situations of sample firms. This study carries practical policy implications for the listed firms, regulators and stakeholders in general. For example, regulatory bodies may promote greater involvement in CSR activities by listed companies in the Malaysian stock market. Investors and other market participants should be aware of factors influencing socially responsible firms’ market performance such as the corporate life cycle and the level of competition in product markets. This research work responds to the call of regulatory bodies in Malaysia at a time when the Malaysian economy is under threat of environmental distraction practices by the palm oil industry and import ban by the largest export market, i.e. the European Union by 2030. The study also  contributes to the theoretical literature by refining the moderating role of product market competition and mature-stage life cycle.

What would make the “elusive” green consumer actually choose sustainable products? This research draws from “dopamine hypothesis of reward” to demonstrate that  physical activity/exercise (regular and immediate) is a vital factor in determining consumers’ sustainable behaviors. More specifically, it examines the role of physical activity/exercise on sustainable consumption behaviors as well as the role of emotional intelligence and sustainability claims. Five studies were conducted to test the hypothesized relationships. The findings from Study 1a and 1b establish direct causal link between physical activity/exercise and customers’ sustainable consumption behaviors. Studies 2a and 2b show that emotional intelligence (trait‐based and ability‐based) may explain the effect of physical activity/exercise (regular and immediate) on sustainable consumption behaviors. Finally, the findings from Study 3 demonstrate that sustainability claims moderate the effect of emotional intelligence on sustainable consumption behaviors. These findings offer significant implications for retailers and marketers to use physical activity/exercise as a strategic intervention to positively influence consumers’ evaluation and behaviors toward sustainable product.

The objective of this study is to explore the blockchain-enabled value creation process in supply chain finance (SCF). We analyze the roles of participants (who?), motives (why?), resources (what?), and practices (how?) through the lens of service-dominant logic and social exchange theory. We conducted an exploratory case study of a blockchain-based platform that offers SCF solutions for supply chain partners and interpreted the results through a series of qualitative analyses. The results prove that the blockchain-driven SCF solution provides services to its customers by applying key resources and conducting corresponding practices, which create value for the participants through meeting their motives.

  • Guo, X., Zhou., Q., Bian, J. (2022). Online retailers’ platform-based Worry-Free-Shopping: Retailing strategy considering consumer valuation bias. Transportation Research Part E: Logistics and Transportation Review, 167, 102902.

Platform-based Worry-Free Shopping (WFS) is an emerging retail service system developed by online platforms. Online retailers on such platforms can actively decide whether to provide WFS services for consumers. If WFS service is offered, a WFS logo will be displayed on the product information page by the platform. Although WFS can enhance consumers’ willingness to pay, it incurs cost for online retailers and may cause more product returns due to valuation bias. This paper investigates when an online retailer on a platform should offer customers WFS, and it explores the detailed effects of WFS on the retailer, platform, customers, and society. We find that both the retailer and platform do not necessarily benefit from WFS. Although the platform can take a ‘‘hands-off » attitude towards the retailer in most cases, they may have conflicting interests while providing WFS, so we have developed a mechanism to coordinate their benefits. Our results explain why the platform develops such a WFS service system, and when it should incentivize the online retailer to offer WFS to customers. Furthermore, WFS always hurts customers when the valuation bias is small, while it may favor the society when he WFS cost is low. In extensions, we verify the robustness of our results and also get new insights. First, a small product salvage value motivates the platform to encourage the retailer to offer WFS. Second, though a larger proportion of overestimating customers always benefits the platform, it may hurt the retailer when it is less than a threshold. Finally, a larger heterogeneity in valuation increment allows the retailer to charge higher price and benefits the platform.

We investigate the insourcing versus outsourcing decision for a manufacturer, facing a price- and carbon emission-sensitive demand and an environmental regulation in the form of a carbon tax. We consider the carbon emissions generated during the production phase. In case of outsourcing, the transportation emissions are also considered, and we investigate the outcomes of revenue sharing and cost sharing contracts between the manufacturer and the supplier. We study the impacts of customers’ environmental  awareness, carbon tax, price sensitivity, market potential, and supplier’s location on the insourcing vs. outsourcing decision, the environmental performance and the selling price. Our results show that a higher customers’ environmental awareness, a larger market potential and a longer distance between the supplier and the manufacturer favor insourcing over outsourcing, whereas a higher carbon tax and a higher price sensitivity favor outsourcing.

The growing literature on game theory models in project management is reviewed in this paper. A systematic study that includes collecting materials, defining the structural dimensions and categories, presenting a descriptive analysis, and evaluating the results has been carried out. Application areas of game theory in project management were explored and the research gaps were identified. The literature review revealed the need for studying knowledge-sharing mechanisms to enhance project governance and cooperation, developing dynamic models to integrate various sources of uncertainty, optimizing different financial objective functions to improve the project’s capital structure, developing integrated scheduling techniques to facilitate project planning and control, and formulating strategies to improve bidding under fierce competition. These findings contribute to identifying the promising directions in the management in engineering research.

In disaster management problems, supply and distribution chains of relief commodities have been one of the most critical parts of planning for both pre- and post-disaster phases. Providing relief items (medical supplies) for injured people can directly affect the vitality rate, and this would perfectly explain the necessity of implementing such practical studies in this field. Thus, a scenario-based, multi-period, multi-objective, two-stage, location-allocation model for providing relief commodities to demand points in an uncertain environment is proposed in this study. Humanitarian constraints (equitizing the number of distributed items and the service time as well as prioritizing areas in receiving the commodities) are also considered in the model to make it closer to reality. Such other practical contributions as redesigning the supply chain and addressing volunteers’ help in the supply and distribution processes are formulated as well. Moreover, using the triage concept for distributing vital items is presented for the first time in this study. The proposed non-linear model is initially linearized and then solved by applying the epsilon-constraint technique. Due to the NP-Hardness property of the model, an NSGA-II and a hybrid algorithm are also presented to solve larger-sized instances. Solving numerical examples and conducting sensitivity analysis verify the applicability and efficiency of the proposed model as well as the solution algorithms and provide some managerial insights to improve the performance of the relief logistics.

Dilemmas related to the use of environmental resources concern diverse populations at local or global scales. Frequently, individuals are unable to visualize the consequences of their actions, where they belong in the decision-making line, and have no information about past choices or the time horizon. We design a new one-shot extraction game to capture these dynamic decisions. We present results from a nationwide common pool resource experiment, conducted simultaneously in eleven French cities, involving a total of 2813 participants. We examine, for the first time, the simultaneous impact of several variables on the amount of resource extracted: the local vs. the national scale of the resource, the size of the group (small vs. big), the low vs. high recovery rate of the resource, and the available information. We show that individuals significantly reduce extraction levels in local as compared to national level dilemmas and that providing recommendations on sustainable extraction amounts significantly improves the sustainability of the resource. Overall, women extract significantly less, but care more about preserving the local resource; older participants extract significantly more resources but extract less from the national resource. Our experiment also fulfills a science popularization pedagogical aim, which we discuss.

Annals of Operations Research (2022) volume 318 issue 1 pp 531–556

Research on the development of sustainable supply chain models is highly active nowadays. Merging the concept of supply chain management with sustainable development  goals, leads to simultaneous consideration of all economic, environmental and social factors. This paper addresses the design of a sustainable closed-loop supply chain including suppliers, manufacturers, distribution centers, customer zones, and disposal centers considering the consumption of energy. In addition, the distribution centers play the roles of warehouse and collection centers. The problem involves three choices of remanufacturing, recycling, and disposing the returned items. The objectives are including the total profit, energy consumption and the number of created job opportunities. As far as we know, these objectives are rarely considered in a sustainable closed-loop supply chain model. The proposed model also responds to the customer demand and also addresses the real-life constraints for location, allocation and inventory decisions in a closed-loop supply chain framework. Another novelty of this research is to develop a set of efficient Lagrangian relaxation reformulations and fast heuristics for solving a real-world numerical example. The results have revealed that the obtained solution is feasible and the developed solution algorithm is highly efficient for solving supply chain models. Finally, a comprehensive discussion is provided to highlight our findings and managerial insights from our results.

Athletes must decide which online self-representation strategy best serves them, including the decision to posting nudity. This study investigates whether male athletes’ experiences differ from those of female athletes and how sponsors, social, and cultural expectations influence their strategies. Guided by impression management and  objectification theories, this study compares online impression management practices of sixteen competitive male and female athletes representing eleven nations. Semi-structured interviews were conducted with all athletes, and their responses were compared to their practices based on observation of their Instagram posts. Athletes of both genders face objectification dilemmas when managing their online image. Fear of homophobia is influencing online impressions of male athletes with nude content, while females feel pressured to use nudity to draw more engagement

Climate change and CO2 emissions intertwine corporations and society in current political, social, environmental, and economic debates, specifically in Europe. The climate action plan formulated by the European Commission aims to achieve net zero emissions through eco-innovation by 2050. The objective of this study is to investigate the impact of the European eco-innovation index on CO2 emissions produced by European firms. Using a dataset of 735 firms from 17 European countries listed during 2010–2018, we found a significant negative association between the country-level eco-innovation index and CO2 emissions directly produced by the European firms. We also found a significant negative association between the eco-innovation index and indirect CO2 emissions produced by the value chain of these firms. The results provide evidence that via eco-innovation, supportive steps taken by European countries provide a conducive environment for the European firms to adopt eco-innovative strategies that significantly reduce their direct and indirect CO2 emissions per dollar of their corporate assets and make their value chains eco-friendly. The results also reveal that financial development brings in some environmental monitoring that cultivates a supportive culture for the corporations to promote corporate efforts to reduce CO2 emissions.

Several machine learning techniques and hybrid architectures for predicting bitcoin price movement have been presented in the past. Our paper proposes a hybrid model encompassing classification and regression models for predicting bitcoin prices. Our analysis found that the automated feature interactions learner (deep cross networks) error performance using a plethora of technical indicators, including crypto-specific technical indicator difficulty ribbon compression and control variables such as Metcalfe’s value of bitcoin, number of unique active addresses, bitcoin network hash rate, and S&P 500 log returns, in a hybrid architecture is better than the single-stage architecture. The hybrid model predicted a 100% directional hit rate and maintained steady volatility in returns for the out-of-sample period. Our paper concludes that in terms of risk (Sharpe ratio 1.03) and profitability (260% and 82%), the hybrid model’s bitcoin futures strategy performed better than the deep cross network regression and buy-and-hold benchmark strategies.

Crowdsourcing is a multidisciplinary research area that represents a rapidly expanding field where new applications are constantly emerging. Research in this area has investigated its use for citizen science in data gathering for research and crowdsourcing for industrial innovation. Previous studies have reviewed and categorized crowdsourcing research using qualitativemethods. This has led to the limited coverage of the entire field, using smaller discrete parts of the literature and mostly reviewing the industrial aspects of crowdsourcing.This study uses a scientometric analysis of 7059 publications over the period 2006–2019 to map crowdsourcing research to identify clusters and applications. Our results are the first in the literature to map crowdsourcing research holistically. In this article, we classify its usage in the three domains of innovation, engineering, and science, where 11 categories and 26 subcategories are further developed. The results of this article reveal that the most active scientific clusters where crowdsourcing is used are environmental sciences and ecology. For the engineering domain, it is computer science, telecommunication, and operations research. In innovation, idea crowdsourcing, crowdfunding, and crowd creation are the most frequent areas. The findings of this study map crowdsourcing usage across different fields and illustrate emerging crowdsourcing applications.

Human accomplishments have increased the complexity and interconnectedness of environmental threats, resulting in widespread effects on people, ecosystems, and economies worldwide. In addition to overpopulation, pollution, burning fossil fuels, and deforestation, humans also impact the physical environment in many ways. These changes have contributed to climate change, soil erosion, poor air quality, and undrinkable water. We investigate the linear and non-linear effects of natural resources and education on CO2 emissions in the Latin American (LA) group of nations considering the roles of green energy, foreign remittances, and economic growth from 1990 to 2020. We have developed a comprehensive empirical analysis that applied second-generation advanced econometric methodologies in this study. The results of this research disclosed that natural resources pose a non-linear impact on environmental quality. The low level of natural resources benefits the environment in the LA panel, but higher use of natural resources ultimately intensifies CO2 emissions. Hence, a U-shaped association between natural resources and CO2 emissions is found in the LA panel. In the linear model, natural resources also boost CO2 emissions. Alongside this, education also intensifies CO2 emissions in the selected sample. Green energy and remittances mitigate CO2 emissions and thereby improve environmental quality.

  • Junhui Zhang, M.S. Balaji, Jun Luo, Subhash Jha (2022) Effectiveness of product recommendation framing on online retail platforms. Journal of Business Research, Volume 153, 2022, pp 185-197

Online retailers often display product recommendations using recommendation framing or signage. Recommendation framing—such as customers who viewed this also viewed or compared similar items—reflects user- or product-related inputs used by the algorithmic product recommender system to identify products for a target customer. The current study examined the effectiveness of norm-based recommendation framing and comparison-based recommendation framing on customers’ click-through intention of the products recommended by online retailers. Four studies were conducted to test the proposed hypotheses. Findings revealed that norm-based recommendation framing is more effective than comparison-based recommendation framing and that the perceived value of the recommendations is the underlying mechanism engendering this result. Furthermore, we observed that the effectiveness of norm-based recommendation framing was only apparent when fewer products were recommended and when the recommended products were highly substitutable for the focal product. Theoretical and managerial implications are discussed regarding online retailers’ efforts to manage improved recommendation-framing strategies.

Supplier reliability is a critical issue for manufacturing companies. Delivery delays from suppliers create backlog and firefighting on the shop floors. To avoid disruption and hedge against supplier lead time un- certainty, companies rely on diversification, multi-sourcing, and safety lead times. In multi-sourcing, the buyer might order the same product (raw material) from different suppliers. The design of a robust and cost-efficient purchasing/ordering plan in multi-sourcing is a complex task which has a strong impact on the performance of the company. In this study, we investigate the use of robust optimization for the integrated lot-sizing and supplier selection problem under lead time uncertainty. More specifically, we use polyhedral budgeted uncertainty sets. The resulting model determines the ideal lot sizes to minimize the total costs taking into consideration suppliers’ reliability and prices. To solve this problem, a row and column generation approach is proposed. To alleviate scalability issues, we enhance the row and column generation through a robust counterpart formulation, and we propose an efficient fix-and-optimize ap- proach. Our extensive computational experiments show that the fix-and-optimize approach yields good quality solutions within a reasonable amount of computational time. We provide insights into supplier diversification based on the risk profile of the decision-maker. One of the conclusions is that an extremely risk-averse decision-maker selects a single supplier, namely the most reliable one even if it does not offer the lowest price.

  • Breslin, Dermot (2022) When Relationships Get in the Way: The Emergence and Persistence of Care Routines. Organization Studies, 2022, Vol. 43(12) 1869–1890

Past research has shown that routines can be a vehicle for both stability and change in organizations. It is unclear however how this relationship alters and solidifies over time. In this paper, the changing behaviours of three newly formed teams within a domiciliary care organization are tracked over a period of two years. It was seen that self-reinforcing processes shaped the emergence and persistence of action patterns within these groups. The first process achieved coordination benefits which drove the emergence of routines, as ‘action patterns’ were first negotiated and then assigned to members of the care team. The second selfreinforcing process involved sets of expectations which deepened interpersonal relationships between the care worker and client. The impact of both these processes, altered the ostensive-performative duality, as routines emerged and persisted over time. This study therefore highlights the changing dynamics of stability and change within routines, and the key role played by social relations in this process.

Our paper contributes to emerging management research on the effects of societal inequality. It aims to study the relationship between societal-level inequality and perceived unequal HR practices within organizations based on relationships which we term “relation-based inequality” (RBI). We further examine the moderating effect of  country corruption on the RBI employee commitment link. Thus, whereas previous research has looked at single countries, there is still much to know about societal effects of inequality and corruption on employee perceptions and attitudes at work across countries. By surveying 691employees from five countries and using country-level indicators we take a first step in this direction, and establish that inequality (income, health and education) is linked to higher levels of relation-based HR practices. We also show that the effect of RBI is different for continuance, affective and normative commitment, and contingent on country corruption levels.

In response to the increasing awareness of sustainability issues, companies have reevaluated their approach to research and development (R&D). Taking into account the long-term effects and consequences of R&D projects on social, economic, and environmental conditions, this research has presented a comprehensive methodology for planning pharmaceutical holding company project portfolios by considering both sustainability dimensions and profitability objectives. The first phase of the developed methodology consists of a new combined MCDM method that is used to determine the sustainability score of each project. The following phase focuses on developing a bi-level bi-objective optimization model that is designed to take into account the decentralized structure of pharmaceutical holdings to optimize the budgeting, selection, and scheduling of projects. This optimization model proposes that the head office of the holding company as leader allocates R&D budgets between subsidiaries as followers to maximize the holding company’s profit and sustainability. In contrast, the followers are responsible for selecting and scheduling research projects. We examine the optimal strategy of each actor using an illustrative case to validate the methodology. Based on experimental results, an approach focusing on sustainability versus profitability (or vice versa) has a significant impact on decisions made at each level of operation. The results reveal that the proposed approach can be adopted by the holding companies to improve the performance of portfolio planning from the sustainability perspective.

Policy uncertainty (PU), and sustainability disclosure, influence the performance of the firms. We use European data to extend the nascent literature on sustainability disclosure, and economic policy uncertainty by investigating the moderating impact of sustainability disclosure on the relationship between economic policy uncertainty and firm performance. We find overwhelming evidence that policy uncertainty reduces firm performance; however, sustainability disclosure moderates this destructing impact of policy uncertainty on firm performance. Our results show that environmental and social disclosure by the European firms enhances their reputation and help these firms in reducing the policy-induced uncertainty. A higher governance disclosure representing efficient corporate governance also help European firms to moderate the negative effect of policy uncertainty on their performance. Our results are robust to alternate proxies of firm performance as well as endogeneity issues.

Research in corporate environmental practices has shown that stakeholders impose coercive and normative forces that drive firms to perform environmental protection actions. However, limited attention has been placed on how different constituents of stakeholders value the firm’s environmental actions. By focusing on industry peers as a constituent of stakeholders, we examine how the firm’s environmental actions impact its reputation. Based on institutional theory and signaling theory we propose that symbolic environmental actions negatively affect reputation, whereas substantive actions improve firm’s reputation among its peers. Building on the notion of signaling process, the authors also observe that a firm’s reporting practices moderate positively the negative effect of symbolic actions. Data from a sample of 213 publicly traded firms operating in polluting industries from 2006 to 2013 support these results. The findings emphasize the danger of using symbolic actions to signal environmental commitment in a context of high-involvement information search and opportunistic behaviors.

This combines natural language processing of article content with probabilistic learning of the latent (hidden) topics that link groups of articles. We show that this body of research can be well-described by 18 overall topics and provide a structure for computational economists to adopt this approach in other avenues.

Emerging country firms have been increasingly engaging in cross-border mergers and acquisitions, and these acquirers predominantly acquire firms from developed countries. The motivation for such acquisitions is to achieve market access but also to benefit from transfers of cross-border managerial skills and knowledge. The performance of such acquisitions has started to receive some research attention, particularly financial performance, but the transfers to other areas such as marketing have not yet been explored. This article addresses this gap by studying the experience of 34 acquirers from emerging countries which acquired firms in developed countries. This study uses two-stage window data envelopment analysis (DEA) and Tobit regression to investigate the impact of these acquisitions on the marketing capability and overall firm performance of the acquiring firms. The results show that the marketing capability of the acquiring firms did improve in the post-merger years and this improvement can be partly attributed to the acquisition. The findings also show that the overall performance of the acquiring firms improved following acquisition, but this is a continuation of superior performance from the pre-merger years rather than a synergistic gain from the acquisitions.

In order to implement or maintain a green supply chain (GSC) that produces goods and services responsibly and sustainably, supply chain managers should use tools that allow for the efficient identification, quantification, and mitigation of the ever-present risks. The objective of the present research is to identify the risk factors associated with the processes involved in GSC management. Based on an analysis of the characteristics of GSC risk, the authors put forward a list of risk design principles and a risk criteria evaluation system for a GSC. Gray relation analysis method was then used to clarify the degree of connection between certain supply chain risk factors and select key risk factors. Finally, Back Propagation Artificial Neural Network (BP-ANN) method was used to determine the risk level associated with a GSC. The determination of risk level will help companies to develop effective strategic management initiatives in a GSC environment.

This study attempts to analyze the ability of the top 10 cryptocurrencies in enhancing portfolio returns of the 10 worst-performing stocks in the S&P600, S&P400 and S&P100 indexes, to match those of the 10 best-performing stocks therein. Applying probabilistic utility approach with different algorithms and time horizons, we find that addition of cryptocurrencies to traditional stock portfolios adds value in terms of enhancing returns. This is consistent with the growing literature on the hedging properties of cryptocurrencies against traditional financial assets.

The purpose of this study is to investigate themoderating impact of corporate governance (CG) on the relationship between economic policy uncertainty (EPU) and the sustainable growth (SG) ofChinese firms. The study collects data of 975 Chinese non-financial listed firms for the period from 2010 to 2017. The study measures SG using a comprehensive index based on nine financial indicators and applies industry and year fixed effects regression to investigate the direct and moderating impact ofCG on the relationship between EPU and SG of Chinese firms. The results of the study explain that EPU negatively affects SG, while concentrated ownership, board independence and board gender diversity (BGD) positively contribute to the SG of the Chinese firms. The results also explain that concentrated ownership and BGD reduce the negative impact of EPU on the SG of the Chinese firms. The study considers only non-financial firms; therefore, the results of this study cannot be generalized for financial firms. Future research can be carried out while considering financial firms as a unit of analysis. The investigation of the negative impact of policy uncertainty on SG is essential for the government and policymakers to devise policies to reduce uncertainty. The investigation of the moderating effect of CG enriches the literature on corporates’ response to policy uncertainty. It provides valuable insights for corporates regarding CGmechanisms to attain SG. To the best of the authors’ knowledge, this is the first study that investigates the moderating impact ofCG on the SG of Chinese firms using an index-basedmeasurement of SG.

Unbalanced assembly line research has grown in importance because of its increasing applications in emerging economies, reverse logistics and remanufacturing. This paper examines the performance of numerous simulated patterns for reliable unbalanced manual merging assembly lines. The contribution of this study to the literature is that imbalance does not always negatively impact efficiency and that it can improve merging line performance when compared to a corresponding balanced merging line. The best performance was found to be a balanced line configuration and a monotone decreasing order for both parallel merging lines, with the former generally resulting in a lower throughput and the latter resulting in a lower average buffer level than that of a balanced line.

The study examines the role China plays compared with the US in transmitting contagion to South Asia. Trade intensity, economic downturns, and negative net equity capital outflows positively influence dynamic conditional correlations between South Asian and US/Chinese financial stock returns. Chinese and US financial firms transmitted more spillovers than they received during the global financial crisis. Results are robust to the use of USD or local currency returns, and the alternative specification of the Diebold–Yilmaz model. The role of Chinese financial firms in transmitting shocks to South Asia may be of interest to policymakers, regulators, and other market participants.

The emergence of the sharing economy has had a tremendous impact on the tourism industry; however, few quality management mechanisms exist for shared tourism services. Based on unique data of 52,248 transactions collected from BlaBlaCar, the world’s leading ridesharing platform, this study examines the independent and combined effects of quality cues on travelers’ demand for peer-to-peer ridesharing services. The findings suggest that intrinsic cues (product reputation and seller reputation) and extrinsic cues (relative price and offer duration) are decisive in increasing demand, and their combined effects can be positive or negative. In addition, analyses of the heterogeneous effects of intrinsic and extrinsic cues across seller segments clarify how consumers evaluate product quality using information from multiple cues. These findings contribute to the literature on tourism and marketing by providing new insights into the design of competitive product offers in the sharing economy.

This paper seeks to expand our understanding of sustainable entrepreneurial ecosystems by investigating the interrelation between contextual factors and sustainable entrepreneurial activities of sharing ventures. While the sharing economy is considered as a potential pathway to a more sustainable society,; ambiguous activities of some sharing ventures call the credibility of sharing as a sustainable concept into question. In order to shed light on the underlying cause of the ambiguity, we conducted 37 in-depth interviews with founders and senior managers of sharing ventures. Our comparative analysis identifies two distinct sets of contextual factors, which influence their sustainable activities. The first set of contextual factors enhances sustainable activities by enforcing the adaptation of behavioral rules and by enabling the development of organizational capabilities. The second set of contextual factors restricts sustainable activities by impeding market penetration and by suppressing growth. We contribute to theorizing about sustainable entrepreneurial ecosystems by delineating the conjoint effect of contextual factors on sustainable activities. Furthermore, our results add insights into the controversial academic debate about the sustainability dimension in the sharing economy.

  • Liu, Y., and Hu, H. 2021. Online Review Helpfulness: The Moderating Effects of Review Comprehensiveness. International Journal of Contemporary Hospitality Management Volume 33 Issue 2 pp. 534-556

Consumers’ evaluation of online review helpfulness has been widely examined. The extant literature suggests that the attributes of review content (e.g. review length and extremity) influence review helpfulness. However, review length cannot fully reflect the richness of the review content. Anchoring on information diagnosticity and extremity bias, this study aims to explore the effect of review comprehensiveness on its helpfulness. Field observations were obtained from 11,812 online restaurant reviews on a popular restaurant review platform. A controlled experiment was conducted to further delineate the effect of review comprehensiveness. Review comprehensiveness moderates the effects of review length and an extremely negative review on helpfulness. It also confirms that for reviews of the same length, one covering more aspects is perceived by consumers as more helpful. Different aspects of information in a review can efficiently assist decision making. The results suggest that review platforms can better design their interface by providing separate areas for different product aspects. The platform can then receive more comprehensive and helpful reviews and increase the diagnosticity of these. The study enriches the literature by introducing review comprehensiveness and examining the joint effects of review length and comprehensiveness on helpfulness. It also contributes to the literature by indicating how to reduce the effect of review extremity.

  • La Rocca, A., & Snehota, I. (2021). Mobilizing suppliers when starting up a new business venture. Industrial Marketing Management, Volume 93, February 2021, Pages 401-412

Prior research has shown that new ventures can complement their capabilities and extend their limited internal resources by drawing on suppliers. Yet, our knowledge of the supplier mobilization process in new ventures is limited. In this paper, we take a relational perspective on the mobilizing process, which entails investigating the scope for mobilizing suppliers in new ventures and new ventures’ attractiveness to suppliers. Drawing on three new venture cases, we posit that for new ventures the scope for mobilizing suppliers: 1) ranges from the use of suppliers for the procurement of well-defined existing inputs to the co-development of various resources and capabilities with suppliers; 2) varies across ventures, reflecting the new venture’s distance to market; and 3) depends on the supplier’s assessment of the new venture’s attractiveness as a customer. We also argue that the attractiveness of new ventures as customers to the suppliers is based on elements that differ from those found in studies of ongoing businesses, and include: 1) stimuli to innovate and develop new competencies, 2) reputational benefits and prestige, and 3) personal satisfaction.

The use of renewable energies has become very attractive, because it protects the environment and boosts regional development. In this paper, a sustainable two-phase sequential approach is proposed for the design of bioenergy SCs under uncertainties. The first phase, integrating geographical information, social aspects, and multi-criteria decision-making techniques, helps find appropriate locations for the bio-refineries. High rates of unemployment, and high vulnerability to the variation in the markets in an economic crisis are considered as social concerns. Integrating these factors filters the areas for the second phase. The first phase reduces complexity in the computation of the problem and helps set up sustainable development in the supply chain. In the second phase, to cope with the uncertainties in the bioenergy supply network, a robust model is introduced. It reduces the sensitivity to inaccurate input data, and the obtained solutions stay optimal when the parameters change slightly. In order to validate this two-phase sequential approach, a case study is investigated. The results of tests show that integrating the concepts of uncertainties and sustainability with geographical information of the area in a two-phase sequential approach outperforms the traditional models and leads to the creation of 262 jobs. The jobs have a high impact on the surrounding area.

The current study aims to understand the detrimental effects of COVID-19 pandemic on employee job insecurity and its downstream outcomes, as well as how organizations could help alleviate such harmful effects. Drawing on event system theory and literature on job insecurity, we conceptualize COVID-19 as an event relevant to employees’ work, and propose that event strength (i.e., novelty, disruption, and criticality) of COVID-19 influences employee job insecurity, which in turn affects employee work and non-work outcomes. We also identified important organization adaptive practices responding to COVID-19 based on a preliminary interview study, and examined its role in mitigating the undesired effects of COVID-19 event strength. Results from a two-wave lagged survey study indicated that employees’ perceived COVID-19 event novelty and disruption (but not criticality) were positively related to their job insecurity, which in turn was positively related to their emotional exhaustion, organizational deviance, and saving behavior. Moreover, organization adaptive practices mitigated the effects of COVID-19 event novelty and criticality (but not disruption) on job insecurity. Theoretical and practical implications are discussed.

  • Romain Espinosa, Gregory DeAngelo, Bruno Deffains, Murat Mungan, Rustam Romaniuc (2021) The price of expungements. International Review of Law and Economics, Volume 65, March 2021, 105976

Expungement mechanisms allow first-time offenders to seal their criminal record. Theory predicts that the stigma of a criminal record can hinder the reintegration of criminals for whom legal activities are less lucrative. In theory, expungements priced at the reservation level can facilitate the reintegration of criminals without making first-time crime more attractive. This paper considers a behavioral perspective and offers experimental evidence about the impact of expungements priced at different levels. To do this, we set up a laboratory experiment where subjects repeatedly face opportunities to commit crime (takemoney from another subject). In addition to stochastic formal sanctions – imposed by the experimenter– we introduce endogenously determined social sanctions. In our main treatments of interest, subjects who choose the wrongful action have the opportunity to expunge their record prior to the second stage, thus avoiding social sanctions as long as they do not recidivate. Overall, our experiment shows that, from a general deterrence perspective, it is better to implement expungements at very high prices. We offer an explanation for this result based on the idea that the price of expungements may signal the moral reprehensibility of the offense.

One of the most applied value scales in research is personal shopping value (PSV) by Babin, Darden, and Griffin (1994). PSV assesses consumers’ shopping experiences along hedonic and utilitarian value. The purpose of this research is the corroboration of the original article and the PSV scale to investigate the impact of the past 25 years on the scale’s dimensionality and item composition. The corroboration mirrors the original store environment, while an extension additionally considers two contemporary shopping environments: online websites and mobile apps. Results across six studies confirm shopping value’s two-dimensional structure of work and fun. However, individual items capturing hedonic and utilitarian value deviate from original PSV scale items in number and nature for current stores, online, and mobile apps environments. Researchers and practitioners should exhibit caution to blindly administer or adapt measures without considering temporal or contextual aspects of the scale that limit its applicability.

  • Alexakis, C., Vasilis Pappas, Manolis Skarmeas (2021) Market abuse under different close price determination mechanisms: A European case. International Review of Financial Analysis 74 (March 2021) 101707

We examine the presence and the severity of closing price manipulation across two regulatory shifts in the close price determination mechanism in the Athens stock exchange. First, we assess the transition from a value-weighted average price (VWAP) method to a plain-vanilla closing call auction method (CCAM). Second, we examine the effectiveness of additional features of CCAMs in deterring closing price manipulation. We use tick level data with full investor details for a group of highly traded stocks. Our results suggest that the CCAM managed to reduce – but not eliminate – closing price manipulation. CCAMs with additional anti-manipulation features are not effective in eliminating closing price manipulation either. Manipulation is dynamic and investors quickly adapt to new circumstances and opportunities; post-CCAM implementation sell-based closing price manipulation has increased, while part of the manipulation activity has shifted to the reference price formation.

This paper offers the first-ever look at Bitcoin options by investigating the wedge between optimum Bitcoin option prices based on classical option valuation models (Black-Scholes-Merton and the Heston-Nandi GARCH (1,1)) and actual premiums at which these options are trading. For this purpose, we use near-the-money call and put options traded on Deribit platform as on 27.01.2020, with the maturities ranging from January 31 to 25 September 2020. In addition, we analyse the risk inherent in Bitcoin options by calculating their Greeks and comparing them to those of traditional commodity options. Pricing results suggest slight overpricing and underpricing for Bitcoin call options with the strike $8,000 maturing on 30.01.2020 and 28.02.2020, respectively. We also find that the Bitcoin options provide much stable deltas over time compared to the other commodity options. This result implies higher insulation from undue price rises with the passage of time for investors in Bitcoin options. Our results are useful to regulators, investors and market managers in better understanding the nuances of the Bitcoin options market in addition to making more informed investment choices.

A large-scale field experiment in Rotterdam, Netherlands, tested whether nudging could increase public transport use. During one work week, 4000 commuters on six bus lines, received a free travel card holder. On the three bus lines in the experimental condition, the card holders displayed a social label that branded bus passengers as sustainable travelers because of their bus use. On the three bus lines in the control condition, there was no such message on the card holders. Analysis of the number of rides per hour showed that the intervention led to a change from pre-intervention (619 days) to postintervention period (176 days) that was estimated to be 1.18 rides per day greater on experimental lines than on control lines. This experiment shows that public transport operators can increase public transport use by incorporating messages that positively label passengers as sustainable travelers in their communication strategies.

The short-term room rental online platforms have boomed in the era of digital business acceleration, as they offer excellent opportunities for interactive behavior between host and guests. However, pursuing customer repeated bookings is a challenge on these platforms. How to increase customer repeated bookings in the short-term room rental market? We examine theoretically and empirically this crucial research question. Drawing on the theoretical foundations of the social interaction theory, we identify and study three host-guest interactions that can affect customer repeated bookings: overall interaction, individual interaction, and offline interaction. We conduct a combination of empirical methods, including text mining and econometrics, using longitudinal data of 36,072 order records and review contents from 5002 listings and 2181 hosts in six cities, which is a prevalent short-term room rental services provider in China. We find that overall host-guest interaction (online reply rate, acceptance rate, confirmation time) and individual host-guest interaction (the existence of individual interaction, absolute text length, and text similarity) increase customer repeated bookings. We also discover that offline host-guest interaction is a substitute for the effect of individual interaction (existence, text length, and similarity) on customer repeated bookings.

This study considers two retailers that offer substitutable products and compete in a greenness- and price-sensitive market. The retailers rely on supply chains that have different costs, replenishment times and carbon intensities. The demand is stochastic, and the inventory replenishment time is also stochastic. Each retailer decides the greenness of its product (carbon intensity), the price and the order size to maximize its expected profit under a service level constraint. The mean demand for each retailer decreases in its price and carbon intensity and increases in other retailer’s price and carbon intensity. The customers’ switchovers are, thus, governed by disparities in carbon intensity and price. The retailers may have different market powers since the total demand is not necessarily equally shared between them when they offer the same price and greenness level. We derive analytically the best response of each retailer to other retailer’s decisions at the Nash equilibrium. We determine the market conditions that lead the competing retailer to offering a greener or a dirtier product than the product it would have offered in a monopolistic situation. We explain how the retailer’s market power impacts on its greenness strategy under different market conditions. We also investigate insights into the impact of disparities in transportation carbon emissions, the order size decisions, and the retailers’ optimal profit under the different competition scenarios.

While antispeciesism is an ethical notion, veganism is behavioral. In this paper, we examine the links between the two. Building on Blackorby and Donaldson (EconJ 102:1345–1369, 1992), we consider a two-species model in which humans consume animals. The level of antispeciesism is conceived as the weight on animals’ welfare in the utilitarian social welfare function. We show that more antispeciesism increases meat consumption if and only if animals’ utility is positive. That is, the critical condition is whether farm animals’ lives are worth living. We then empirically explore this condition using a survey. We find that farm-animal experts and frequent meat eaters are more likely to believe that the lives of farm animals are worth living. We finally discuss some issues in the study of animal welfare in economics and social choice.

We conducted and analysed 14 in-depth structured interviews with managers in 2007 and again in 2017. Thematic analysis shows that in 2007, managers focused on instrumental motivations for CSR, citing economically driven artefacts and pro-environmental efforts. In 2017, most managers reported increased and reinforced environmental and social engagements with a parallel shift in the expression of their motivations, seeing CSR as a responsibility to society and future generations, or as a normal, natural activity.

Online peer-to-peer (P2P) lending volume has rapidly increased in China because of high financing and investment demands. However, high borrowing default and fraud rates have negatively affected Chinese online P2P lending because of its unique financial and unde¬veloped credit systems. They have prompted the Chinese government to issue regulations on Internet finance behavior to support online P2P lending. This research investigates online P2P lenders’ investment perceptions to understand investment intention related to online P2P lending. The research model is based on planned behavior theory. A ques¬tionnaire on attitudes collected data from voluntary participants; the data were analyzed with confirmatory factor analysis and structural equation modeling. The findings show that lenders’ attitudes, behavioral controls, and subjective norms—and those three constructs’ antecedents, except relative advantages—have a positive and significant influence on lend¬ers’ online P2P lending intentions.

This paper examines the determinants of the emerging market banks’ derivative usage and the impact of derivative usage on bank value, total risk and bank stability. Our empirical evidence first suggests that derivative usage is driven primarily by net interest margin, bank concentration and institutional strength. In addition, although derivative usage appears to reduce emerging market bank value, it does not affect total risk. Moreover, emerging market banks can reduce bank instability using derivatives. Our findings have important implications for investors and policy makers focusing on emerging derivatives markets.

Snacking typically occurs as an automatic, consciously uncontrolled process which can lead to unintended health consequences. Grounded cognition informs about the multifaceted drivers of such automatic consumption processes. By integrating situation-, stimulus-, and person-specific factors, this study provides a holistic account of snacking. A combined psychophysiological and behavioral experiment is conducted wherein participants can casually snack chocolate while participating in a survey setting. Implicit cognitions are assessed with the Implicit Association Test. The percentage of consumed chocolate serves as dependent variable in a Tobit regression with predictors at situation, stimulus and person level. Findings – Chocolate snacking is positively influenced by personal craving tendencies, implicit food associations and situational contingency. We condense the results into an overarching framework in line with grounded cognition literature. The multidimensional framework can guide consumer protection efforts to reduce excessive snacking habits based on situation, stimulus and person. This study integrates theory from social cognition, consumer research, and behavioral food research and, thereby, extends the existing body of knowledge on grounded cognitions underlying snacking consumption.

Research on social networks and innovation emphasizes that individuals spanning structural holes and crossing institutional boundaries have more opportunities for knowledge recombination and innovation involvement. However, transforming the potential knowledge and resources available through personal networks to attain innovation can be difficult for the focal individual. Using an ego-network approach, this study examines whether and to what extent an individual strategic orientation to cooperation (i.e. tertius iungens) contributes to strengthening the relation between two personal network properties (structural and institutional separation) and involvement in innovation. Our analysis is conducted in the context of biomedicine, where research networks are particularly relevant for science and innovation achievements. Our findings advance social network theory by decoupling social network mechanisms from individual strategic networking behavior as factors influencing knowledge generation processes. Results also provide original evidence on an overlooked phenomenon: the moderating role of a tertius iungens orientation in the relationship between multiple social network properties and innovation. Finally, our research sheds new light on the distinct sources of knowledge recombination in networks and the role of individual networking strategies to facilitate mobilization of resources for innovation.

Research has largely shown a positive linear relationship between proactive personality and job performance at the individual level. However, it remains unknown whether the same relationship holds at the team level. In this research, we propose and test a curvilinear relationship between team mean level of proactive personality and team performance. We also examine team potency and team cohesion as the explanatory mechanisms and the dispersion of proactive personality as a boundary condition for the relationship. We conducted two studies to test these ideas. In Study 1, we collected data from 93 teams in four companies from different industries. In Study 2, we collected data from 101 nursing teams in three hospitals. We found a curvilinear relationship between team mean level of proactive personality and team performance in Study 1 and replicated it in Study 2. We further demonstrated in Study 2 the moderating role of dispersion of proactive personality and the mediating role of team potency and team cohesion, respectively, in this curvilinear relationship. The positive trend of the curvilinear relationship is strengthened (weakened) when the dispersion of proactive personality is high (low). The negative trend is mitigated under high dispersion of proactive personality but is not significant under low dispersion of proactive personality. Practically, managers must be aware that team mean level of proactive personality benefits team performance only up to a certain point

While extant research on entrepreneurial ecosystems has focused on macro-level factors influencing the ecosystem’s development, the role and impact of entrepreneurial practices have been neglected. The objective of this study is to address this research gap and to shed light on the micro-level practices of entrepreneurs who support sustainability transitions in entrepreneurial ecosystems. Our inductive study looks at these micro-level practices from the perspective of sustainable ventures situated in the sharing economy. We conducted 31 in-depth interviews with the founders and senior managers of sustainable ventures to investigate how they advocate the sustainability cause in their ecosystem. Our findings show that sustainable entrepreneurs rely on three distinct sets of micro-level practices: building a supportive environment, disrupting normative standards, and reframing the sustainability paradigm. Also, sustainable entrepreneurs engage in political work to strengthen their position and credibility in the sharing economy, which is being increasingly dominated by profit-oriented players and business practices. By substantiating the central role and micro-level practices that sustainable entrepreneurs enact to advocate sustainability, our study contributes to theorizing the sharing economy. Furthermore, our resultant framework provides a detailed overview of the distinct micro-level practices that help ventures to support the sustainability transition in entrepreneurial ecosystems.

The carousel is an important automated storage and retrieval system. Customer orders to be collected from carousels are grouped into batches and the orders of a batch are collected simultaneously. We study two batching methods for picking from multiple carousels: (i) fixed batching, where all orders belonging to a batch are collected before the next batch is started, and (ii) rolling batching, where each time an order belonging to the current batch is completed, it is immediately replaced by a new order. For these methods, the main decision is respectively to allocate orders to different batches and to define a sequence for adding orders into batches. With the objective of minimising the total completion time, we develop models for fixed and rolling batching. Thanks to our collaboration with the company KLS Logistic Systems, we use real data to test and prove the efficiency of our models. With comparison to current batching strategies of real companies and to benchmark heuristics, our models yield a considerable time saving. Our findings also indicate that an increase in order size favours the rolling batching over the fixed batching. The models developed in this paper have been implemented and are currently being used in practice

This study examines how carbon performance affects carbon disclosure and how carbon disclosure affects financial performance. With a sample of global firms, the study analyses how relationships between carbon disclosure, carbon performance and financial performance vary in institutional contexts. Our results show that carbon disclosure positively affects carbon performance, consistent with the signalling theory. We find that carbon disclosure negatively (positively) affects financial performance in the short-term (long-term). Our findings have significant implications for investors as some firms use carbon disclosure as part of impression management. Our results help regulators to monitor carbon disclosure and assist investors with investment decisions.

Journal of Consumer Behavior, Volume 20, Issue 3, pp.550–563

Consumers’ internalisation of social norms is at work when they make routine, healthier food choices in everyday contexts. We investigate the dynamics of this phenomenon in Singapore, where over 98% of consumer food products are imported. To study this, we propose, through a consumer perspective (n = 316) via Partial Least Squares Structural Equation Modelling (PLS-SEM), a model that establishes a positive relationship between perceived usefulness, subjective norms, and intrinsic motivations and the perceived value of healthier food. Subjective norms are themselves found to be a function of perceived barriers, facilitating conditions and personal innovativeness. Our framework contributes to establish a shift in the drivers of healthier food choices toward a more socio-culturally grounded decision-making approach that is particularly relevant to understand food consumption. We show that daily food routines (opposing the exceptional healthy food item) are encapsulated in perceived value of healthier eating. The data indicates further that to support healthier food product consumption, both policy makers and food providers must facilitate imported foods that meet quickly changing lifestyle requirements.

Antecedents of intention to adopt artificial intelligence and robo-advisory services from the German private investors’ perspective may guide future adoption behavior. This paper raises the question to what extent German investors’ is willing to use robo-advisory services instead of a human advisor to manage their investments. The exploratory study identified the following constructs that impact the intention to use artificial intelligence to invest: perceived risk, perceived usefulness, perceived ease of use, social influences, and intention to use. Findings from this study can help inform marketers when developing strategies to foster awareness and the adoption of roboadvisors.

  • Castillo, A., Benitez,J., Llorens, J., Luo Xin (2021) Social media-driven customer engagement and movie performance: Theory and empirical evidence. Decision Support Systems, Volume 145, Issue 1, 113516

Can social media-driven customer engagement help movie producers to increase movie sales? Movie producers use social media to boost customer engagement; however, our understanding of whether there is a relationship between pre-consumption customer engagement and movie sales is limited. This research explores what drives the success of movies on the opening-weekend. We examine the relationship between pre-consumption customer engagement driven by social media (i.e., personal and interactive engagement) and movie performance (i.e., opening-weekend box office revenues). Driven by the debate about the potential capacity of social media-driven customer engagement to improve movie performance and the limited understanding of the association of pre-consumption customer engagement and movie performance, this research suggests that social media-enabled customer engagement (i.e., personal and interactive engagement) has the potential to improve movie performance, and these two types of engagement can interact to make this effect stronger. We analyze these relationships drawing from the uses and gratifications theory and the social media affordances perspective that motivate customers to interact in social media. The theoretical model evaluation was tested on a unique and original dataset composed of 966 movies released in the U.K. and Spain. The empirical analysis suggests that personal and interactive engagement are positively related to movie performance, and the positive effects of personal and interactive engagement on movie performance are mutually reinforcing. This research contributes to Information Systems (IS) research by theorizing and empirically showing how customer engagement driven by social media creates business value by improving movie performance.

Do software vendors propose, create, and capture value in the era of digital transformation? Drawn on the literature of business models, digital innovation, and firms’ capabilities, we examine this cutting-edge research question. We conducted a multiple case research of 10 software vendors operating in Germany and Austria. The thematic analysis yields a conceptual model that explains whether and how software vendors leverage cloud computing-enabled innovation for the digital boost, which is this study’s primary contribution to information systems research. Software vendors use a complementary portfolio of information technology and organizational capabilities to innovate in their value proposition, creation, and capture.

  • Hammami, R., Frein, Y., Albana, A.S. (2021) Customer rejection to guide lead time quotation and pricing decisions. Journal of the Operational Research Society, 72(6), 1358-1372

The lead time (LT) quotation and pricing models in make-to-order environments usually assume that all arriving orders are accepted. Hence, despite the loss of demand, the firm must quote a relatively long LT to tackle the situations where there are too many waiting orders. This paper investigates the policy of accepting orders based on the state of the system and, consequently, rejecting customers when the number of waiting orders is larger than a given threshold value. Indeed, if there are less than K jobs in the system (K fixed), then the new order is accepted and a pair of LT and price are quoted to the customer. Otherwise, the order is rejected. Thus, we model the firm’s operations as a M/M/1/K queue instead of the commonly-used M/M/1 queue. We determine the optimal solution for K = 1 and solve the problem numerically for K ≥ 2. We show that our policy can be more profitable than the all-orders acceptance policy. We provide insights into when should a K be imposed and how such a K should be chosen. We find that the higher the sensitivity of demand to price or to LT is, the lower the optimal value of K.

This paper provides a systematic review and analysis of the game-theroy-based research in Green Supply Chains Management (GSCM). Based on a rigorous content analysis of 108 papers carefully selected from the literature, we present a detailed picture of the current state of this research and point to the promising future directions. Our analysis shows a rapid increase in the number of publications during the last three years, with an imbalance in the contribution of the publishing outlets, as nearly two third of the reviewed papers are published by only four journals. Results also show the dominance of deterministic static models and simple two-level SC structures. Developing stochastic models, considering the risk and the evolutionary nature that inherently characterise the business environment and investigating more complex multi-level SC structures are among the promising future research opportunities.

In this study we quantify and analyze the dynamic dependence between US, eurozone, UK and Japan Bitcoin market returns and realized and unexpected inflation, conditional on different market states and various nuances of inflation. Using a Quantile-on-Quantile regression, we investigate the hedging properties of Bitcoin against inflation, thereby offering a fresh look at the return-inflation puzzle from the point of view of alternative investments. We find that while bullish UK, Euro and Japanese Bitcoin markets facilitate hedging against inflation by offering higher returns, the USD Bitcoin market performs worse with inflation. In general, our results indicate an asymmetric relationship between inflation, both realized and unexpected, and alternative investments such as the Bitcoin market.

Consumers’ responses to design features involve both conscious and non-conscious information processing. The current research therefore argues that a combination of explicit and implicit measures should be used to assess consumer understanding of service brand meaning conveyed by a service brand’s physical elements. However, most methods traditionally used to evaluate design meaning are explicit methods, based on conscious cognitive processes. The current research addresses this gap by documenting how understanding of service brand meaning conveyed by a service brand’s physical elements can be tapped by an implicit measure. More specifically, it aims to investigate the extent to which a greater ability to decode meaning conveyed by design features results in differences in implicit understanding of service brand meaning. This research uses a Semantic Priming Task to assess associative strength between brand meaning and a service brand’s physical elements. Results (N ¼ 157) show that command of the design language, captured by design acumen and involvement in the product category, results in greater ability to implicitly understand brand meaning conveyed by a service brand’s physical elements, and moderates the implicit-explicit relationship. Results suggest that combining implicit and explicit measures may help practitioners in charge of creating brand’s physical elements, especially when associations between design types and brand impressions are not constant across product categories.

Research on the relationship between novelty and travel intention is lacking. This study attempts to fill this gap by developing a theoretical model to explain how novelty influences travel intention through two mediating paths: brand equity and tourist motivation. In this study, data were collected from 466 foreign visitors to Taiwanese night markets. To test the model, the authors applied structural equation modeling (SEM) to identify the critical attributes that predicted foreign tourists’ travel intentions. The SEM analysis indicated that novelty in tourism management was related to brand equity and intrinsic motivation, which increased foreign tourists’ travel intentions and offered advantages for highly competitive, high-density night markets in Taiwan. In addition, brand equity was an important mediator that connected novelty and tourists’ travel intentions. Finally, novelty indirectly affected travel intention and intrinsic motivation through brand equity. There may exist potential moderators in the relationships among the brand equity and travel intention categories. Future research studies could explore whether any moderators influence the relationship mechanisms examined in this study. This research expands on previous research studies that have focused on the value of travel intention. Furthermore, the study uses brand equity theory (BET) and the theory of planned behavior (TPB) to examine the mediating effect of intrinsic motivation on the relationship between novelty and travel intention.

This study examines the impact of tenure in independent directors and audit committees on accretive share buybacks for real earnings management. Taking a sample of 601 non-financial firms listed on Bursa Malaysia from 2010 to 2015, we use a tobit model to test our hypotheses, where real earnings management is proxied by accretive share buyback. We find a significant effect of the tenure of outside directors on accretive share buyback. Firms with long-serving independent board directors are more likely to undertake real earnings management through accretive share buyback. Evidence is also found that firms with audit committees including long-serving members are more likely to engage in share buyback to maximise reported earnings per share (EPS) for earnings management. Finally, a high percentage of independent directors on audit committees restrain managers from utilising accretive share buyback to manage reported EPS.

In the real world, various products are displayed simultaneously on the shelf; therefore, their demands/prices affect each other. This paper aims at studying a joint economic lot-sizing model with two complementary products in a supply chain consisting of a vendor and a buyer. The vendor sends items to the buyer’s warehouse in equal-size batches applying vendor-managed inventory with consignment stock policy. The buyer stocks items at the warehouse and on the shelf. Two mixed-integer nonlinear models that consider bundling and separate sales have been proposed and solved through different solution algorithms such that the profit is maximized. The concavity of both models’ objective functions is investigated and the effect of considering complementation between products and bundling strategy is studied. Numerical experiments indicate that the bundle’s marginal profit is greater than a single product’s marginal profit. Moreover, the supply chain members can also take advantage of economies of scale in bundling sales.

This study investigates the influence of buyer–seller personality similarities on compulsive buying behaviour in a dyadic setting. To provide insights into the gaps in previous research, we collected both buyer and corresponding seller data, and considered sellers’ personalities. Specifically, using difference score analyses and variance-based structural equation modelling, we analysed 1038 buyer–seller dyads in service encounters. Compared with the effects of individual buyers’ personalities on compulsive buying, the combined personality results showed that buyer–seller agreeableness similarities increase the compulsive buying behaviour of agreeable buyers. On the other hand, buyer–seller similarities in openness and neuroticism reduce compulsive buying. A further analysis showed that buyer–seller interactions mediate the effect of their extraversion and openness similarities on compulsive buying, while buyers’ shopping enjoyment mediates the effect of their extraversion and neuroticism similarities on compulsive buying. Overall, compulsive buyers have interpersonally different buying behaviours when their personalities match (differ) with their corresponding sellers’. Thus, marketers can match agreeable buyers with similar sellers to promote sales, while dissimilar sellers should be complemented with openminded and neurotic buyers, in particular, to reduce losses.

Environmental non-governmental organizations (ENGOs), one of the major forces in environmental protection, have developed rapidly in the past few years, especially in developing countries such as China. This paper aims to reveal how the ENGOs select their focuses, specifically if they only concentrate on one focus or on contexts in which they obtain various focuses and the motivations behind their choosing strategies. The current research interviewed 103 leaders of ENGOs covering every province in mainland China and adopts existing theories of NGOs alongside diversification strategy from a management perspective. The results showed that most Chinese ENGOs now tend to be diversified but face different challenges. This research highlights the importance of ENGOs’ resources and capacities in facing current challenges and suggests directions to improve their diversification strategy. This research adds value to the research of environmental NGOs and gives suggestions to environmental NGO practitioners, in particular to those in emerging markets.

This paper examines the effect the impostor phenomenon (IP) on short-term emotions (shame) and performance (creativity and organizational citizenship behavior- OCB) at work, and on career outcomes. Previous research shows direct detrimental effects of IP on some short-term performance measures, but effects on creativity and OCB remain under-researched, and no work has investigated any career effects. Through an experimental approach (Studies 1 and 3) and an online vignette (Study 2) using working populations, we find that IP is expressed as shame in response to simulated and recalled real work events. Shame mediates the negative effect of IP on creativity, and its positive effect on OCB, and mechanistic organizational structure exacerbates the negative shame-creativity relationship. Furthermore, Study 4 uses a survey design to reveal that IP relates negatively to external employability and career success. Drawing on conservation of resources theory, we suggest that IP and shame deplete resources such that impostors suffer reduced ability to perform well at work in the short-term, with negative consequences for career success.

NGOs often vary in terms of how radical they are. In this paper, we explore the effectiveness of NGO discourses in bringing about social change. We focus on animal advocacy: welfarist NGOs primarily seek to improve the conditions in which animals are raised and reduce meat consumption, whereas abolitionist NGOs categorically reject animal use and call for a vegan society. We design an experiment to study the respective impact of welfarist and abolitionist discourses on participants’ beliefs regarding pro-meat justifications and their actions, namely their propensity to engage in the short run in animal welfare (charity donation, petition against intensive farming) and plant-based diets (subscription to a newsletter promoting plant-based diets, petition supporting vegetarian meals). We first show that both welfarist and abolitionist discourses significantly undermine participants’ pro-meat justifications. Second, the welfarist discourse does not significantly affect participants’ actions, although we detect a potential backlash effect of the abolitionist discourse. We show that the NGOs’ positive standard effect on actions through the change in beliefs is outweighed by a negative behavioral response to the discourses (reactance effect). Last, greater public-good contributions are associated with greater engagement in animal welfare in the presence of an NGO discourse.

The Covid-19 pandemic continues to disturb the global economy and capital markets. Governments across the globe relentlessly enact health policy measures to contain coronavirus and undertake economic relief programs to reduce the impacts on their economies. This paper examines the effects of Covid-19 government health measures on the volatility of capital markets in East Asian economies. The study applies Monte Carlo type simulations to determine stock price volatility over the period when health policy measures were implemented. The findings indicate that different health policy measures have affected investors’ behavior and caused volatility of stock markets. However, there are country-different impacts on the volatility of these capital markets. The findings provide important insights that are useful when reviewing Covid-19 health policy measures to mitigate the impacts on stock markets.

Buoyed by the desire to reduce carbon dioxide emissions and develop sustainable urban transportation, the dockless bike-sharing industry boomed in China during 2017–2018. To the surprise of the stakeholders, this industry dramatically ebbed in 2019. The dockless bike-sharing system deviated from a problem-solver to a troublemaker in a very short period. The oversupplied and excessively discarded shared bikes caused a big waste of resources and serious pollution to the environment. In this paper, the decision-making of the key players of the industry, i.e. business operators, investors, customers and government, is analyzed through the lens of the cognitive bias. This paper aims to illuminate the process of how this innovative transport solution turned to a disastrous ending, which caused damage to urban environment and financial loss to investors. In this study, a qualitative analysis based on the rich secondary data sources is conducted. A rich amount of qualitative data including news reports, government policies, consulting reports and companies’ annual reports etc. were collected. The study shows, in the product introduction period, the government, business operators, investors and consumers fell into the cognitive bias. They over focused on the positive side such as high-tech, eco-friendly, convenient image of the dockless bike-sharing solution. Thereby, the key stakeholders made irrational decisions in product adoption and management. This study moves toward increasing key stakeholders’ awareness of the imperative to reduce these biases when promoting eco-innovations. This study also recommends a prudent attitude with a rational and comprehensive thinking style in dealing with eco-innovation and the emerging sharing economy. To solve the cognitive biases, this study recommends that people use rational decision-making style to examine and adopt the dockless bike-sharing solutions. Practical recommendations to tackle the existing recycling crisis of the dockless bike-sharing industry are also discussed.

How to enter and expand in a newly emerged foreign market is less understood. Should multinational enterprises move fast or slowly? In this study, the authors take China as the context to investigate what factors will lead to a fast expansion strategy in a foreign market. The purpose of this paper is to understand whether fast expansion benefits firms’ performance in a rapidly emerging market. Based on insights from field interviews, the authors developed a theoretical framework. Then, the authors collected data from surveys of managers of multinational enterprises from Western countries to test their hypothesis. This research context is based on the experience of multinational enterprises in China which opened up to foreign direct investment in 1979. This study shows that internally, strategic long-term investment goals, top management team commitment and externally switching costs and the growth in the demand market which will push firms to expand fast in the newly emerged China market. Faster pace of expansion benefits the performance of multinational enterprises in a newly emerged market. Based on the onsite interviews followed by the survey of top managers of multinational enterprises located in China, this study provides a fine-grained analysis of the importance of pace and its key antecedents. Thus, the results provide new insights to decision-makers of multinational enterprises when considering expanding in an emerging market at its early stages of growth.

Promoting energy conservation in university dormitories is challenging because student residents are typically charged a flat utility fee. One possibility to curb excessive energy use in the absence of monetary incentives is to highlight the environmental consequences of energy use. However, it is still largely unknown how these consequences should be communicated to effectively change people’s behavior. In the present study, we analyzed the effect of framing the environmental consequences of energy use in terms of losses versus gains on the air-conditioner use of student residents of a Japanese university dormitory. A total of 330 students were provided with stickers to attach to the air-conditioner remote control in their dormitory room during the winter term. The stickers conveyed that increasing the temperature will hurt the environment (loss frame), that reducing the temperature will protect the environment (gain frame), or that changing the temperature will affect the environment (neutral frame). Day-to-day variations in objective air-conditioner use data were analyzed as a function of experimental condition to examine the effect of message framing. The change in air-conditioner use from pre-intervention to intervention period did not differ between experimental groups and neither did the change from pre-intervention period to a period after the intervention

We investigated how hotel customers’ satisfaction is influence by the financial performance of the hotels. We extracted the satisfaction ratings from Trip Advisor for 3,4 and 5 star hotels in Greece. Financials wee extracted from hotels’ financial statements. Our findings show that the hotels in each star category have different financial profiles and attract different customer satisfaction ratings. 5-star hotels attract the highest customer satisfaction score and also have greater asset investment, more beds, and higher revenue/bed. In terms of expenses, the 5-star hotels have higher cost of goods sold, and lower administration and selling expenses as a proportion of revenue. Lastly, there is a lower prevalence of swimming pools in 5-star hotels, perhaps partially reflecting the business focus as opposed to tourism focus of these hotels.

Bitcoin futures were introduced in December 2017 and this was seen by some as a sign of the most popular cryptocurrency finally being accepted by the financial community. In this paper, we examine the impact of the introduction of Bitcoin futures on the Bitcoin spot market in terms of five characteristics – returns, volatility, skewness, kurtosis and liquidity, using a Bayesian diffusion-regression (state-space) structural time-series model. Our results indicate that the introduction of bitcoin futures potentially exerted a downward impact on the USD bitcoin spot market return and skewness and an upward one on volatility, kurtosis and liquidity, which became higher after futures were introduced. Therefore, our paper offers important insights for investors and regulators, while providing some guidance as to the potential impact of futures markets on other cryptocurrencies.

This study fills a gap in the consumer emotions literature regarding customer frustration in a customer service setting. Most research on customer emotions has examined anger, happiness or affect in general, largely ignoring the particularities of frustration. Consistent with appraisal theory, we use five experiments to explore the different appraisal dimensions that define frustration and its relation to customer loyalty and satisfaction. Contrary to common belief, we show that frustration is not simply the result of goal‐blocking, but rather of a more complex combination of appraisals which differentiate it from anger and lead to distinct effects on satisfaction and loyalty. We also examine how the effects of frustration on loyalty and satisfaction are mitigated by service recovery in a further experiment and an event reconstructive method. Our results test appraisal theory, inform theory on customer emotions and have important implications for our understanding of customer satisfaction and loyalty following frustrating customer service encounters

Sukuk investments require investors and issuers to adhere to subtle moral and ethical standards beyond following mere profit maximization objectives. Investor trust manifested through the level of societal trust could be vital in the global Sukuk investment surge. This study investigates the relationship between the societal trust level and Sukuk activity. It employs a global sample of Sukuk issuances spanning over 2001–2019 and finds that a country’s societal trust level significantly and positively influences the amount of Sukuk issued. Moreover, this positive effect supersedes the negative effects of higher information asymmetry associated with equity-based Sukuk or Sukuk issued by risky firms. Ultimately, trust is both a deterrent and critical for Islamic finance success.

We provide a comprehensive structuring of research on Islamic economics and finance into the core topics of the area, for the period 1979 to 2018. This is carried out through a probabilistic topic modeling approach that allows statistical learning of the connection between research articles as well as their shared topics. This approach, which blends machine learning and natural language processing, helps provide a comprehensive structure to the literature. Our topic modeling analysis is conducted on approximately 1500 articles and suggests the Islamic economics and finance literature can be well-described by 11 topics. These topics cover economic, finance, and morality issues. Our research can be applied to provide a clear structure for ongoing research agendas in Islamic economics and finance as well as a framework for understanding research development in this area. We also note the differences between Islamic and conventional approaches to economics and finance research in order to highlight the inherent new contributions of this maturing area of research.

Whilst research in innovation ecosystems has focused on the connectivity, interdependence, and coevolution of actors, technologies, and institutions, there has been a gap in the study of these relationships between actors, with little explanation given on how mutually interdependent parties adapt. In this paper, we draw further on the ecological metaphor to present a view of innovation ecosystems as complex adaptive systems, where patterns of change emerge from microlevel coevolutionary interactions between actors. Drawing on this view, we explore related implications for our understanding of ecosystem boundaries, coevolutionary rules of interaction, and how ecosystems are energized through innovation. Specifically, we contribute to the literature by developing a novel account of innovation ecosystems where actors are bound together through changing modes of coevolution. Drawing on this account, we explore key theoretical and practical implications for our understanding of ecosystem actors, rules of interaction, and the wider innovation ecosystem. We conclude that innovation both maintains and drives change within the innovation ecosystem, by altering the microlevel rules of interaction and coevolutionary relationships between actors.

  • Michiel De Bauw, Christophe Matthys, Veerle Poppe, Samuel Franssens, Liesbet Vranken (2021) A combined Nutri-Score and ‘Eco-Score’ approach for more nutritious and more environmentally friendly food choices? Evidence from a consumer experiment in Belgium. Food Quality and Preference, Volume 93, 2021, 104276

The application of Nutri-Score on food products is ubiquitous throughout Europe and studies demonstrating its potential to stimulate healthier food choices are accumulating. At the same time, a strong need exists to evenly harmonize and activate the communication of environmental impacts on food products, in synergy with the Nutri-Score. This raises the question of whether the Nutri-Score could be expanded to an ‘Eco-Score’ that would similarly encourage environmentally friendly food choices. This paper reports a randomized control trial, in which a representative sample of 805 Belgian consumers was asked to hypothetically buy ingredients for a meal in a small-scale mock-up E-grocery environment. The experiment tested whether a combined Nutri-Score and Eco-Score affected the nutritional quality and environmental impact of consumers’ food choices. This effect was compared to general and specific dietary recommendations on the one hand, and to detailed impact tables on the other hand. Since visual distraction often plays a role in informative persuasion, the treatments were evaluated subject to different levels of distraction caused by product images. The average nutritional quality index (NQI) and environmental impact index (EII) of the selected baskets were calculated to evaluate the effects of the manipulations. We find that a joint Nutri-Score and Eco-Score label improves the NQI but not the EII. The general- and specific recommendation as well as the detailed information also improved the NQI. However, the specific recommendation was the only treatment that also improved the EII. The improvements in NQI due to the scores could be explained by a reduced consumption of pork. The improvements in EII induced by the specific recommendation could mainly be explained by a reduction in beef consumption. Only very mild indications were found that product images interfered with the effect of the scores. This study provides some initial evidence and support for the use of dual Nutri-Score – Eco-Score label to induce transitions towards healthier and more sustainable diets. We also find that recommendations outside the classic Front-Of-Package label framework could be a promising way to realize such a transition. However, it remains to be tested whether similar effects occur in real E-groceries and on a longer time scale.

Although both institutional export assistance and entrepreneurial orientation (EO) contribute separately and positively to export performance, the interplay between them has received little attention. This study examines the role of international EO in deriving performance benefits from governmental and nongovernmental export assistance. In this longitudinal study, two surveys were administered at two different times: In 2011, 705 Bangladeshi apparel exporters were surveyed, and in 2019, a subsequent survey of 198 firms in multiple industries was conducted. The aim of the surveys was to assess the relationships between governmental and nongovernmental assistance, EO and export performance. The results of the first survey show that, while nongovernmental assistance influences performance directly and via EO, governmental assistance has only direct effects. Furthermore, the negative influence of government assistance on EO reduces the total effects and renders them nonsignificant. The results of the second survey demonstrate that government EPPs have both direct and indirect positive and significant effects on market performance, indicating a partial mediation, whereas quasi-governmental assistance has positive and significant direct effects as well as negative but nonsignificant indirect effects. Nongovernmental EPPs have both direct and indirect significant effects on international performance, indicating a partial mediation. The study has important implications for researchers studying export assistance and its impact on firm performance. Instead of adopting a parochial view of government assistance, this study categorizes such assistance into three types – government, quasi-government and nongovernment. Furthermore, this study bridges the export assistance and international entrepreneurship literature by including EO. Entrepreneurs must emphasize the use of government assistance in order to enhance export performance. However, to promote both entrepreneurship and performance, they must emphasize nongovernment assistance. Exporters should also capitalize on the assistance extended by various quasi-governmental agencies to bolster export performance. Given the performance advantage of export assistance, this study highlights the contribution of the private sector in promoting export entrepreneurship while shedding light on the pernicious role of (quasi-)governmental assistance in export entrepreneurship.

  • Rahman, M., Rodríguez-Serrano, M.A., Hughes, M. (2021) Does Advertising Productivity Affect Organizational Performance? Impact of Market Conditions. British Journal of Management,32: 4, pp 1359-1383

Advertising is crucial in influencing customers’ perceptions and purchase intentions, and numerous studies have investigated whether advertising expenditure has any significant impact on financial performance. A thorough understanding remains elusive: while several studies document a positive impact, others report that advertising has either a negative or a statistically insignificant effect. Three flaws among existing studies are responsible for this problem: bundling advertising with other forms of marketing, the inadequacy of expenditure as a measure and a failure to consider contingencies. Deviating from earlier studies, we examine the effect of advertising productivity on firm performance rather than the impact of the absolute amount of advertising expenditure. Moreover, adopting a contingency approach, we evaluate how market conditions of market dynamism, market complexity and market munificence moderate the relationship between advertising productivity and organizational performance. Drawing a multi-industry sample from the USA, this study demonstrates that advertising productivity has a positive impact on capital market-based performance measures, conditional on market conditions. We reveal new insights into when, why and to what extent advertising contributes (or not) to organizations’ financial performance.

  • Mahabubur Rahman, M. Ángeles Rodríguez-Serrano & Anisur R. Faroque (2021) Corporate environmentalism and brand value: A natural resource-based perspective, Journal of Marketing Theory and Practice, 29:4, 463-479

Given ever-increasing engagement of firms in corporate environmentalism over the past few decades, a multitude of studies investigated the antecedents and consequences of corporate environmentalism. Extant studies exploring the consequences of corporate environmentalism predominantly measured its effects on firm performance. However, to the best of our knowledge, no study thus far has explored whether or not the key pro-environmental initiatives pertaining to corporate environmentalism carried out by industrial firms have any effect on market-based assets, namely, brand value. This study endeavored to address this gap in the literature. Drawing on natural resource-based view of the firm (NRBV), this study argued that industrial firms committed to corporate environmentalism reap rewards in the form of higher brand value. This study investigated three salient areas of corporate environmentalism, namely, environmental innovation, efficiency in using natural resources and emission reduction. The findings of this research demonstrate that industrial firms that outperform in environmental innovation, use fewer natural resources, and reduce emission have a higher brand value. Interestingly, while environmental innovation and efficiency in using natural resources contribute fairly equally to brand value, ability to reduce emissions contributes the least to brand value creation.

  • Yildirim, C. and Kasman, A. (2021) Market power evolution and convergence in European banking: An Empirical note. Bulletin of Economic Research Volume 73 issue 4 pp. 535– 544

This paper undertakes an up-to-date assessment of evolution and convergence in market power over 2013 and 2018 in the Eurozone banking markets in view of the progress towards completing the banking union. The results show that average market power measured by the Lerner index displays an upward trend up until 2016 declining thereafter. Further findings by employing the panel convergence methodology of Philips and Sul (2007) fail to support the hypothesis of integration in the Eurozone banking markets through market power convergence. Furthermore, club clustering tests reveal presence of three sub-clusters of countries with different speeds of convergence.

This study examines the relationship between board gen­der diversity and the corporate financial performance (CFP) of companies listed on the Qatar Stock Exchange. We use the ordinary least square (OLS) regression as the baseline technique along with the system GMM generalized method of moments (GMM) approach to mitigate the possible issue of endogeneity. Our analysis reveals that board gender diversity negatively affects CFP. Our findings are robust to the use of alternate measures of board gender diversity and free from endogeneity concerns as demonstrated by the re­sults of the system GMM regression estimates. Further, we explain the possible reasons of this negative relation, par­ticularly in the context of Qatar. An important implication of our findings is that they identify the factors that inhibit the women in Qatar from making significant contributions to board proceedings as well as to CFP in its male-domina­ted society.

  • Saqib Aziz, Mahabubur Rahman, Dildar Hussain, Duc K. Nguyen (2021) Does corporate environmentalism affect corporate insolvency risk? The role of market power and competitive intensity. Ecological Economics, Volume 189, 107182

Little is known about the effects of green performance on corporate insolvency risk. This study examines the relationship between green performance and firm insolvency risk from both theoretical and empirical perspectives. Using a panel of 179 US firms included in the Newsweek Green Rankings and a system generalised method of moments estimation which generates endogeneity-robust regression coefficients, we found that firms with higher green performance are at lower risk of insolvency. We further postulate and provide theory-based empirical evidence that the nexus between green performance and insolvency risk is contingent upon other internal and external boundary conditions. Specifically, this research documents that the nexus between green performance and firm insolvency risk is moderated by market power as well as industry competitive intensity. The results of this study are robust across several sensitivity analyses

This paper goes beyond the extant comparisons of Islamic and conventional investments by econometrically assessing their convergence dynamics, in a dataset spanning over 1996–2020, covering ten business sectors and five episodes of crisis. We use a dynamic multivariate framework to estimate time-varying correlations, which we submit to beta and sigma-convergence analysis. Subsequently we examine how convergence dynamics affect portfolio risk management and crisis propagation. Our results show strong convergence of Islamic and conventional investments. During crises conventional convergence rates double, but Islamic ones are less affected. Sectoral diversification works best for conventional investments; Islamic ones behave as a single entity. On average we document a 7% risk diversification benefit from Islamic investments, at a 64 basis points cost. Yet, at the epicentre of the Covid-19 financial crisis this rises to 466 basis points and highlights the resilience of these investments in an exogenous event. Islamic investments reduce volatility spillovers in the financial system, but they are progressively less insulated across time. Our findings withstand a battery of robustness checks and are primarily useful to policy makers and investors

  • Jbid Arsenyan, Agata Mirowska (2021) Almost human? A comparative case study on the social media presence of virtual influencers. International Journal of Human-Computer Studies, Volume 155, 102694

As virtual agents become prevalent in many domains, virtual influencers have gone live on social media platforms, integrating human networks and interacting with users. Building on research on human-computer interactions, the Uncanny Valley hypothesis, and Computers Are Social Actors paradigm, this paper aims to investigate (1) virtual agents’ similarity to humans in terms of behaviour in human networks and (2) reactions to human versus virtual agents in human networks where this interaction is publicly visible. We analyse the posting behaviour of and reactions to one human, one human-like virtual, and one anime-like virtual influencer active on a popular social media platform via text and emoji postings over an 11-month period. We find that, despite the general positive atmosphere of the platform, the human-like virtual influencer receives significantly lower positive reactions, providing evidence for the Uncanny Valley. Additional measures of negative reactions show a similar pattern. We discuss these results within the context of authenticity and social identity on social media, providing recommendations for the implementation of virtual influencers in human social networks.

This study explores how individuals obtain knowledge, perceive information sources, behave, and form opinions while facing a pandemic at an early stage. We develop a conceptual model linking the predictors of individuals’ knowledge with people’s behavior and opinions. The model is empirically tested through a large-scale global survey of 15,552 respondents from 126 nationalities. Our results indicate that relying on one source of information does not lead to favourable behavior towards curbing the pandemic. Furthermore, we need to educate people and control misinformation spread on policy and social network platforms to curb emergencies collectively

Since the start of the oil counter-shock in June 2014, Algeria has experienced unprecedented twin deficits. The excessive monetisation of the public deficit coupled with other deep anomalies in the economy of this country acutely calls for reconsideration of its monetary policy. To this end a prior study of the long-run stability of money demand is needed. We estimate the demand for money for monetary aggregates M1 and M2, and cash in Algeria over the period 1979–2019, and study its long-run stability. We show that the transaction motive is significant for all three aggregates, especially for the demand for cash, reflecting the weight of informal economy “practices”. The elasticity of the scale variable is very close to unity for M2 and M1, and even equal to unity for cash demand (1.006). The elasticity of inflation is also significant for all three aggregates, although its level is higher in the case of cash demand (􀀀 6.474). Despite the persistence of certain financial repression mechanisms, interest rate elasticity is significant for all three aggregates, but higher for M1 and cash. The same observation is made for elasticity of the exchange rate, reflecting the effect of monetary substitution, especially for M1 and cash. Finally, our study concludes that the demand for money in terms of M1 remains stable, the same observation being confirmed for the M2 aggregate. However, the demand for fiat currency proves not to be stable. The consequences for the optimal design of monetary policy in Algeria are clearly stated.

This paper models a single liner service design and operations problem. The model selects the ports to be included, their sequence, the sailing speed of vessels, the number of vessels and the amounts of cargo to transport by the service. The objective is to maximise profit. First, a relaxation with a mixed-integer nonlinear programming (MINLP) formulation is proposed. We show how to obtain the optimal speed value. Once this value is obtained, the mathematical programming formulation becomes a mixed-integer linear program (MILP). Then, a two-step exact algorithm is presented to solve the problem. Using real data, the optimal solution was found in less than 1 min for small-size problems and in few hours for relatively large-size problems. More tests were carried out on randomly generated data sets with up to 25 ports. The results of these tests are rather promising, and they enabled us to identify the performance limits of the algorithm.

Chinese small and medium-size enterprises (SMEs) in the textile industry adapt and reshape their business models to cope with the environmental changes resulting from increasing labor costs and decreases in profits. Comparing with big firms, SMEs face more challenges when renewing their business operations. Reactions of SMEs are influenced by the extent of changes in the business model renewal process. The renewal of the business model includes resource configuration, updating purchasing and distribution channels, refining market segments, and rebuilding brands.

  • Flichy de La Neuville Thomas. Lessons from Applying Sanctions and Blockades. Review of Business and Economics Studies. 2021;9(4):23-31.

From the geo-economic standpoint, a power may avail itself of a spectrum of constraining measures against a hostile or dangerous nation — measures ranging from sanctions, boycotts to embargos and blockades, which last represent the ultimate form of economic pressure to which an adversary may be subjected. Because they are an extreme type of economic banishment, their imposition reveals the physiognomy of the power struggle; and, because they obstruct the free flow of goods, they also appear to be an ephemeral anomaly within the Liberal world order. Yet, their incumbency in the game is a reflection of geo-economic complexity. Whether enacted to great fanfare or not, blockades freeze some transactions while generating business opportunities elsewhere. And while an activity momentarily stilled in one zone may be reshaped to the advantage of another, blockades still allow their instigators to zero in on key sectors of the enemy’s economy without endangering the country’s survival. Thus, we can see blockades as an economic and military measure serving imperial ends. This essay succinctly reviews the history of famous blockades and garners the core economic lessons one may learn from them.

In this paper, we empirically analyse the performance of five gold-backed stablecoins during the COVID-19 pandemic and compare them to gold, Bitcoin and Tether. In the digital assets’ ecosystem, gold-backed cryptocurrencies have the potential to address regulatory and policy concerns by decreasing volatility of cryptocurrency prices and facilitating broader cryptocurrency adoption. We find that during the COVID-19 pandemic, gold-backed cryptocurrencies were susceptible to volatility transmitted from gold markets. Our results indicate that for the selected gold-backed cryptocurrencies, their volatility, and as a consequence, risks associated with volatility, remained comparable to the Bitcoin. In addition, gold-backed cryptocurrencies did not show safe-haven potential comparable to their underlying precious metal, gold.

This paper analyses herding in cryptocurrency markets in the time of the COVID-19 pandemic. We employ a combination of quantitative methods to hourly prices of the four most traded cryptocurrency markets – USD, EUR, JPY and KRW – for the period from 1st January 2019 to 13th March 2020. While there are several strong theoretical reasons to observe the ‘‘black swan” effect on cryptocurrency herding, our results suggest that COVID-19 does not amplify herding in cryptocurrency markets. In all markets studied, herding remains contingent on up or down markets days, but does not get stronger during the COVID-19. These results are important for cryptocurrency investors and regulators to enhance their understanding of cryptocurrency markets and the financial effects of the COVID-19 pandemic.

Information systems literature suggests that reputation is the main judgment form that captures user-related information online. Drawing on social judgment literature, we contend that a user’s online characteristics and past actions are not all reputation-based, but also legitimacy-based, and that transaction stake determines whether users will use reputation or legitimacy judgment to evaluate other users. Using Airbnb, we show that level of stake in a transaction determines the judgment form (reputation or legitimacy) that guests resort to when evaluating a host. Moreover, we find that providing extensive information on a host to potential guests in low-stake transactions is counterproductive.

Why do organizations develop and execute social media initiatives to create business value? This study addresses this prominent and critical research question for IS research on the business value of social media. Drawing on the institutional theory, we argue that mimetic, coercive, and normative pressure persuade organizations to use social media to improve marketing performance. We test our core proposition and theory-driven research model using data collected from a sample of leading Chinese agribusinesses. We find that coercive and mimetic pressure play pivotal roles in motivating organizations to use social media. We also discover that social media usage improves marketing performance and that the agribusiness market uncertainty plays a positive reinforcing role in the positive effect of social media usage on marketing performance. Thus, this paper contributes to IS research with an eloquent theoretical explanation and strong empirical evidence on why organizations deploy social media initiatives to improve their marketing activities and performance and the higher business value of social media under greater agribusiness market uncertainty.

This study examines the mediating role of green human resource management between ethical leadership and employees’ citizenship behavior towards  the environment with the moderating effect of individual green values. We collected data from 589 MBA executive students with one‐year of experience working in various organizations at two different times using a questionnaire based survey method. Applying structural equation modeling to the results confirmed a direct effect of ethical leadership on employees’ citizenship behavior towards the environment and an indirect effect through green human resource management. Further, individual green value strengthened the association between green human resource management and employees’ environmentally conscious citizenship behavior. Our study contributes to social learning and supply value‐fit theory and has implications for management.

Digital-free tourism limits tourists’ access to information and communication technologies during vacation. It is an emerging trend but tourists’ motivation to take digital-free tourism has not been fully understood. Anchoring on technostress literature, this study examines the effects of the exhaustion from workplace information technology and off-work social network services on tourists’ intention to take digital-free tourism. Survey data involving 300 full-time working individuals show that both techno-exhaustion and social-networkservices- exhaustion have positive impacts on tourists’ digital-free tourism intentions. It contributes to the literature by introducing technostress related constructs in understanding tourists’ digital-free tourism intentions.

We study the interdiction of smuggling network that arranging the activities of the police in order to successfully interdict criminals in smuggling goods. This work contributes to the literature of maximum flow network interdiction problems by addressing asymmetric information, uncertain conditions, multi commodity, and with multiple sources (origins) and sinks (destinations). Information Asymmetry realistically occurs due to incomplete information of interdictor (police) and operator (smuggler) about each other’s performance, which is adapted from the real-world condition. We propose two mixed-integer programming models by reformulating a Min–Max bi-level mathematical model. In the first model, the type of interdiction is discrete (zero and one), while in the second model, the interdiction is assumed continuous, meaning that the partial interdiction is possible. The asymmetry type of the smuggler’s information towards the police have formulated through a linear function while the asymmetry of the police information to the smuggler is formulated using an uncertain parameter through a two-stage stochastic programming framework. To solve the first model, an innovative exact hybrid method is proposed combining of a Decomposition Method and Progressive Hedging Algorithm (DM-PHA). An augmented Karush-Kuhn-Tucker (KKT) method is also used to solve the second model. Several sensitivity analyses are then conducted, and the results demonstrate the applicability and effectiveness of the proposed models as well as the solving approach. It is also shown that the proposed models can be used as a suitable approach in uncertain environment and under asymmetric information to determine the optimal interdiction decisions of police to prevent further smuggling.

  • Canan Yildirim, Adnan Kasman, Fazelina Sahul Hamid (2021) Impact of foreign ownership on market power: Do regional banks behave differently in ASEAN countries? Economic Modelling, Volume 105, 2021, 105654

The change in crossborder financial intermediation and rise in regional banking have consequences for competitive conduct in emerging countries’ banking markets. Using data from the Association of Southeast Asian Nations countries’ banks during 2011–2018, we examine the nexus between foreign ownership and banks’ market power by controlling for the heterogeneity of foreign banks concerning their countries of origin (advanced vs. emerging and regional vs. nonregional). We find that the increasing presence of foreign banks from advanced countries is associated with lower bank market power because of higher marginal costs and lower price–cost margins of the domestic banks. However, the increasing presence of emerging countries’ banks is associated with higher bank market power because of lower marginal costs and prices of domestic lenders. Our findings have implications for policies regarding bank competitiveness and promoting regional banking integration because domestic banks conduct differently under increased participation levels of advanced and emerging country foreign banks.
