The goal of this study is to examine knowledge sharing as a boundary condition under which employee innovation can be enhanced in response to the job stress induced by the COVID‐19 pandemic. We argue that when stressed employees share knowledge, they can expand their knowledge base and thereby enhance their innovative potential. Consistent with our hypothesis, multiple regression analysis results based on a sample of 61 R&D employees of UK and US technology‐based firms show that knowledge sharing moderated the relationship between COVID‐19‐induced job stress and employee innovation, such that the relationship was negative when knowledge sharing was lower but became positive when knowledge sharing was higher. These findings highlight the importance of investing in knowledge‐based resources to promote innovation behavior at work during a pandemic.

This paper examines how corporate social responsibility (CSR) affects bank efficiency in a sample of large commercial banks across 22 countries over the 2013–2017 period. We used a one‐step model of stochastic frontier analysis for panel data to estimate bank profit efficiency and found that the greater the activities in the social and environmental dimensions of CSR, the lower the level of efficiency, whereas activities in the corporate governance dimension are generally not relevant. This result supports the relevance of agent perspectives for these firms. However, we also found that institutional context moderates this baseline result. Specifically, all CSR activities have a positive impact on bank efficiency in common law countries and countries where the effectiveness of stakeholder protection is high. This supports the view that contexts that favor firms' sustainable behavior also increase bank efficiency.

This paper examines the links between product diversification, international diversification and capital structure for a panel of medium and large Italian firms. The results indicate that the interaction between these two dimensions of diversification strategy has a negative and significant impact on leverage. Furthermore, debt maturity analysis reveals that firms pursuing a simultaneous dual diversification strategy have, in particular, lower long-term debt ratios. Our findings support the hypothesis that the complexity that comes from diversification reduces debt levels.
