Gender diversity, financial performance, and the moderating effect of CSR: empirical evidence from UK financial institutions

Purpose This study aims to examine the direct relationship between board gender diversity (BGD) and financial performance and the moderating role of corporate social responsibility (CSR) in the said relationship. Design/methodology/approach Using data collected from the Thomson Reuters Eikon ASSET4 database from 42 UK financial institutions listed in the ESG index for the period 2005–2019, this study used multivariate regression analysis on panel data to test the effect of BGD on financial performance and estimate the moderating effect of CSR between them. Moreover, to control the endogeneity problem, the authors conducted an additional analysis by testing the dynamic dimension of the data set through the generalized moment method. Findings The empirical results show that BGD is positively related to financial performance and that BGD increases firm performance with the moderating effect of CSR. Regarding the endogeneity problem, the existence of continuity between financial institution performances over time is demonstrated. Research limitations/implications The current paper sheds light on the importance of BGD in improving firm performance and the moderating role of CSR in strengthening the relationship between BGD and firm performance, thereby contributing to the agency theory, the resource dependency theory and the stakeholder theory. Therefore, regulators and policymakers in the UK can use the outcomes of this study to enforce the representation of female directors on boards to enhance the financial performance of financial institutions. Moreover, the findings could be useful for regulatory bodies to encourage financial institutions to practice CSR activities and disclose them in their annual reports. Originality/value To the best of the authors’ knowledge, this is the first study investigating the moderating role of CSR on the relationship between BGD and financial performance in the context of the financial sector. It is also the first study documenting that CSR reinforces the relationship between gender-diverse boards and financial institutions' performance. This study fills a research gap as it expands the existing literature that has generally focused on the impact of BGD on financial performance and has not reached similar results.
