Do female directors and their foreign experience complement or substitute for CSR performance? Evidence from the cost of debt financing

Purpose This study aims to investigate the association between corporate social responsibility (CSR) performance and the cost of debt financing (CODF) in Malaysia. It further explores whether the potential impact of CSR performance on debt pricing is moderated by the females’ representation on board and female directors’ foreign experience. Design/methodology/approach The authors use a sample of 845 firm-year observations from 2017 to 2021 and apply various regression techniques, including the pooled ordinary least squares (POLS), the Heckman two-stage self-selection model, propensity score matching (PSM) and quantile regression, to test the study’s hypotheses. Findings The results show that socially responsible firms incur lower costs of debt. Similarly, female directors and female directors with foreign exposure are negatively associated with CODF. However, their impact becomes positive when these two variables are interacted with CSR performance. The study findings are robust across alternative measures of board gender diversity, different model specifications and approaches addressing the endogeneity problem. In additional analyses, we find that the positive implication of CSR on CODF is more pronounced for firms with higher CSR performance and less financial constraint. Nevertheless, the results reveal that only firms with lower CSR performance but a high proportion of female directors and female directors with foreign experience exhibit lower CODF. This underscores the likelihood that female directors and their foreign exposure may substitute CSR practices in mitigating the cost of debt. Originality/value Existing literature generally emphasises the importance of CSR performance to corporate financing decisions, often neglecting the role of female directors and their attributes in financial institutions’ creditworthiness evaluation. This study is among the first to address this gap by examining the moderating effect of female directors and their characteristics on CSR–CODF relationship within an emerging economy context. The findings contribute to the literature on CSR and board gender diversity, indicating that CSR performance and board gender diversity function more as substitutes than complements. Despite the unexpected consequences of interacting with female directors and their foreign experience with CSR, the study affirms the significance of CSR practices and board gender diversity in shaping borrowers’ financial decisions.
