Abstract
Purpose This study aims to examine the effects of board gender diversity on agency costs in non-financial firms listed on the Pakistan Stock Exchange (PSX). Design/methodology/approach Multiple regression analysis is used to determine the impact of board gender diversity on agency cost. The research used panel data consisting of 2,062 firm-year observations of 226 non-financial firms listed on the PSX from 2008 to 2019 to test the proposed hypothesis. In addition, the Blau and the Shannon indices were used to checking for robustness. Findings The results indicate that female presence on the board significantly reduces the agency cost and, hence, mitigates the principal-agent conflict. Moreover, consistent with the critical mass theory, it was found that boards with three or more female directors have a stronger impact on reducing the agency cost, as compared to two or fewer female directors on the board. Research limitations/implications The sample was restricted to non-financial firms listed on the PSX only; therefore, the results reflect the attributes of Pakistan's business environment. A similar analysis in the context of other countries may generate different results. Practical implications The findings imply that female directors play an important role in reducing agency conflicts between shareholders and managers by enhancing monitoring through effective governance mechanisms. The policymakers, therefore, should focus on female career development and encourage professional training programmes to generate a fair, competitive environment for senior female management. Originality/value This study attempts to fill the literature gap in that no similar study covers the non-financial firms' listed firms in Pakistan. The paper supports the reforms made by the code of corporate governance by making the placement of female directors mandatory on Pakistani corporate boards. Overall, support is provided for the view that regulators should favour gender quotas regarding the composition of the board management team of listed firms to reduce agency conflicts and gain shareholder confidence.
