CSR as a catalyst: Examining the effects of board gender diversity on earnings management

The importance of board gender diversity (BGD) is well recognized due to its potential to enhance corporate governance and bring diverse perspectives to decision‐making processes. However, empirical evidence on its benefits, particularly for earnings management (EM), remains inconclusive, reflecting the complex dynamics within corporate boards. Given the inconsistent BGD–EM relationship, researchers are left to examine how, if at all, the two are associated, often encountering mixed results that complicate the narrative. Building on agency and stakeholder perspectives, this paper provides deeper insights into the BGD–EM relationship, emphasizing the mediating role of corporate social responsibility (CSR) as a catalyst that enables BGD to impact EM. We sample 10,252 firm‐year observations from publicly listed firms in 15 European countries from 2010 to 2020. The results show that BGD positively impacts CSR performance by indicating that diverse boards prioritize and implement socially responsible initiatives, leading to strategies that constrain EM practices through a culture of transparency and accountability. The results suggest that women directors are committed to enhancing CSR performance and restraining unethical activities such as financial manipulation and EM, reflecting their tendency to uphold higher ethical standards. Our findings alert firms to the need to focus not only on the importance of BGD but also on CSR activities to ensure higher earnings reporting quality and curb EM practices. By integrating BGD and CSR into their core strategies, firms can create a robust framework that mitigates the risks associated with EM. The results also have important implications for regulators, policymakers, and managers in understanding the drivers of higher EM practice quality. The results highlight the need for regulatory frameworks that encourage gender diversity and CSR, thereby promoting sustainable and ethical business practices.
