Social science research has recently been subject to considerable criticism regarding the validity and power of empirical tests published in leading journals, and business scholarship is no exception. Transparency and replicability of empirical findings are essential to build a cumulative body of scholarly knowledge. Yet current practices are under increased scrutiny to achieve these objectives. JIBS is therefore discussing and revising its editorial practices to enhance the validity of empirical research. In this editorial, we reflect on best practices with respect to conducting, reporting, and discussing the results of quantitative hypothesis-testing research, and we develop guidelines for authors to enhance the rigor of their empirical work. This will not only help readers to assess empirical evidence comprehensively, but also enable subsequent research to build a cumulative body of empirical knowledge.

We investigate the effect of changes in a firm's knowledge couplings on its innovation performance. We develop arguments to explain how changes in couplings among existing knowledge domains and those between new and existing knowledge domains affect the generation of valuable inventions. We also examine how observed domain complexity, an indicator of the inherent interdependencies among knowledge domains, moderates the effects of changes in a firm's knowledge couplings on innovation performance. Our results suggest that a change in couplings among existing knowledge domains hurts innovation outcomes, but not when the degree of domain complexity is high, whereas coupling new and existing knowledge domains leads to improved outcomes, but not when the degree of domain complexity is high.

What can MNEs learn from the COVID-19 pandemic? IB scholars have provided ample insights into this question with many focusing on risk management. Complementing these insights, we argue that MNEs should also consider the long-lasting effect that COVID-19, inter alia, had on the institutional logic underlying globalization. The U.S. and its allies have redefined their logic from pursuing cost-reduction to building partnerships based on shared value, aiming to substitute China’s role in the world economy. The geopolitical pressure for decoupling from China is the source of ‘new’ vulnerability of globalization. Such pressure is counteracted by economic rationality, creating unsettled priority between the globalization and deglobalization logics at the macro-level institutional space. Combining both risk-management and institutional logic perspectives, we develop a more comprehensive framework on how MNEs should respond to these challenges. This paper contributes to the debate regarding the impact of COVID-19 on globalization, suggesting that neither globalization nor deglobalization logics will prevail in the short run, and IB will likely be more fractured in the long run, based on not only geographic but also ideological and value propinquity. In strategic sectors, the balance will shift toward bifurcation while in others the balance will shift toward the globalization logic.

PurposeThis study examines the firm-level financial consequences caused by supply chain disruptions during COVID-19 and explores how firms' supply chain diversification strategies, including diversified suppliers, customers and products, moderate the negative effect on firm performance.Design/methodology/approachBased on data drawn from 222 publicly traded firms in China, the authors use event study methodology to estimate the effects of supply chain disruptions on the financial performance of affected firms. Regression analyses are conducted to examine the moderating effects of supply chain diversification.FindingsFirms affected by supply chain disruptions during COVID-19 experienced a significant decline in shareholder value in two weeks and a subsequent decrease in operating performance in one year. Diversified suppliers, customers and products act as shock absorbers to alleviate the negative effects. Further regression shows a substitution effect between customer and product diversification. Cross-industry comparisons reveal that service firms experienced more loss than manufacturing firms. Customer diversification mitigates the adverse effects of supply chain disruptions for both manufacturing and service firms. Supplier diversification exerts a noteworthy role in manufacturing firms, while product diversification is beneficial for service firms.Originality/valueThe study provides empirical evidence on the magnitude of financial consequences of supply chain disruptions during COVID-19 in both the short term and long term and enriches the current understanding of how to build resilience from the supply chain diversification perspective.

Extensive research has been conducted into the antecedents and consequences of workplace envy, but there have been limited meta-analytic reviews. This meta-analysis draws on social comparison theory to examine studies of envy in the workplace and develop a comprehensive model of the antecedents and consequences of workplace envy. We reconcile the divergent findings in the literature by building a model of three types of workplace envy that distinguishes between episodic, dispositional, and general envy. The results suggest that individual differences (e.g., narcissism, neuroticism), organizational contexts (e.g., competition, position), and social desirability are predictors of workplace envy. They also reveal that workplace envy is related to organizational citizenship behaviors (OCBs), negative behaviors (e.g., ostracism, social undermining), negative emotions, organizational perceptions (i.e., engagement, satisfaction), turnover intentions, and moral disengagement. We test the moderating roles of envy types, measurement approaches, and causal directions. The results reveal that these moderators have little differences, and that some variables (e.g., self-esteem, fairness) may be both antecedents and consequences of workplace envy. Finally, we suggest that future research into workplace envy should investigate contextual predictors and moderators of the social comparison process that triggers envy. This meta-analysis can serve as a foundation for future research into workplace envy.

In \"Probing Theoretically into Central and Eastern Europe: Transactions, Resources, and Institutions,\" we outlined the contributions of research in Central and Eastern Europe (CEE) to theoretical debates in business research. In this retrospective, we reflect upon the evolution of the field over the past decade. With the fading impact of CEE's distinct shared history, we suggest that CEE best be analyzed as emerging economies, rather than as a distinct geographic entity. Emerging economy business research is converging on common themes and shared theoretical ideas, while identifying critical variations that constrain generalizations among and beyond emerging economies. This research thus highlights the need to develop a better understanding of the boundary conditions of scholarly theories of business knowledge. Over the past decade, the institutionbased view has emerged from distinct intellectual traditions in institutional economics, organizational theory, and the analysis of business-government bargaining. Research in these converging lines of theorizing places contextual variations at the center of explanations of business phenomena around the world. We suggest that the institution-based view is evolving toward a paradigm, and offer suggestions on how to advance this research agenda further, in particular by exploring how firms engage with different sets of potentially conflicting institutions at multiple levels and locations.

The last decade has seen marketing strategy evolve rapidly in three major directions, which can be summarized in three Ds: digital, data-rich, and developing markets. The first D refers to “digital”; digital marketing strategy deals with firms’ judicious use of digital resources to create differentiated and sustainable value for customers. The second D is “data-rich”; digital marketing has made available to researchers unprecedented data on firm and customer behavior. The third D is “developing markets”; the issue of marketing strategy in a digital and data-rich context is particularly relevant in developing markets such as BRIC (Brazil, Russia, India, and China) countries. This article formally defines the scopes of the three Ds, identifies opportunities associated with three Ds, and highlights the work published in these areas that will hopefully trigger more research work in D3 environments.

Employing insights from political economics, international relations, and China studies, we identify the key variables that shape the dynamics of the U.S.–China rivalry and investigate their impacts on the bifurcation and value-chain decoupling processes. We show that the ongoing conflict and disengagement processes are more likely to evolve in the long run in significantly different ways to the one envisioned by current Washington decision-makers and echoed by Petricevic and Teece (2019). The latter predicted an escalation of the disengagement processes and inevitable convergence to a ‘bifurcated world’. Our main findings are: (1) The potential costs of bifurcation and consequent value-chain decoupling are prohibitive to both China and the U.S. Resistance is likely to grow by U.S.’ own MNEs and allies; (2) Washington decision-makers overstate the threats that ‘China’s rise’ poses to the survival of the liberal world order; and (3) China’s techno-nationalistic threats are likely to dissipate after a period of escalation, as a result of its own resource constraints, increasing costs of key programs, and inability to sustain in the long run its rapid innovation processes due to growing central controls. We conclude the paper by outlining an approach to maintain an open global economy and secure innovation systems.

Using multisource data and multilevel analysis, we propose that the ethical stance of supervisors influences subordinates' perceptions of corporate social responsibility (CSR) which in turn influences subordinates' trust in the organization resulting in their taking increased personal social responsibility and engagement in organizational citizenship behaviors (OCB) oriented toward both the organization and other individuals. Using a multilevel model, we assessed the extent to which ethical leadership and CSR at the work unit level impacts subordinates' behaviors mediated by organizational trust at the individual level. We employed a sample of 71 work unit supervisors and 308 subordinates from five businesses of a conglomerate company located in mainland China. Subordinates were asked to rate supervisory ethical leadership practices, CSR, and their extent of organizational trust. Supervisors were asked to rate the personal social responsibility taking and OCB of their respective subordinates. A multilevel path analysis revealed that ethical leadership has a positive effect on CSR at the work unit level and that CSR has a positive cross-level effect on organizational trust at the individual level, which in turn significantly and positively impacts OCB through the mediating effect of taking personal social responsibility. Results are discussed in the context of China's manufacturing sector.
