This article examines the relationship between gender diversity, selected female attributes, and financial performance of FTSE 100 firms in the UK. Drawing on critical mass theory by measuring gender diversity as levels of female representation in the boardroom, this study finds a positive and significant relationship between gender diversity and firm performance. However, the results become highly significant and unequivocal when three or more females are appointed to the board compared to the appointment of two or less females. Further analysis reveals that post‐appointment financial performance is positively related to female age, level of education and where female board members also hold executive director positions. The results remain unchanged after accounting for endogeneity concerns and employing alternative measures of firm performance, namely, return on assets and Tobin's Q.

This paper considers the effects of female representation and the proportion of female representation on corporate boards and audit committees on financial performance in an African context where institutions are weak. Employing a panel of 77 firms, our results show that female board representation exerts a positive and significant influence on firm financial performance. The study also finds that the performance effect of gender diversity is stronger for firms with two or more female directors, suggesting that building a critical mass of female representation enhances firm financial performance. Further analysis indicates that the inclusion of females on the audit committee appears to have a positive impact on firm financial performance. Our results are robust after controlling for endogeneity and the use of alternative measures of board gender diversity.

Drawing on institutional theory, we examine the impact of corporate governance (CG) on corruption. The interaction effects of national culture and CG on corruption are also examined. By employing a dataset of 149 countries, our baseline findings indicate that the quality of CG practices reduces the level of corruption. Findings also show that three cultural dimensions, namely, power distance, individualism and indulgence moderate the CG‐corruption nexus. Our findings indicate that CG and national culture explain the level of corruption among societies, with national culture appearing to matter more than the quality of CG. Our findings remain unchanged after controlling for endogeneities, country‐level factors, CG and corruption proxies.
