Corporate governance and bank performance: evidence from banking sector of Pakistan

Abstract

Purpose The aim of this study is to understand how board structure, size of audit committee (AC), gender diversity and ownership structure influence banks’ performance in Pakistan. This study also aims to examine how various dimensions of governance differently affect the different measures of bank performance. Design/methodology/approach This study used panel estimation techniques to quantify the impact of various elements of corporate governance on bank performance by taking annual data of 19 Pakistani banks for the period 2013–2020. The corporate governance is measured by board size, CEO duality, AC size, ownership structure and gender diversity. To get the robust results, this study measures bank performance by considering different indicators, namely, return on assets, earning per share, technical efficiency (TE) and total factor productivity. The empirical investigation is based on several well-known and well-accepted governance theories such as the agency theory, the stewardship theory, the tokenism/critical mass theory and the information asymmetry theory. Findings The findings of the study reveal that the size of board and ACs both significantly improve profitability and productivity, whereas they decrease TE. Further, the findings suggest that most of the indicators of gender diversity significantly deteriorate the performance of banks. However, ownership structure significantly improves banks’ earnings per share and TE. This study further illustrates that CEO’s duality does not have any significant impact on bank performance. This finding holds true for all the performance measures considered for this study. Practical implications The findings are of great importance to various stakeholders, especially to policymakers to know about the factors influencing different measures of performance. Specifically, based on these findings, they can devise the result-oriented strategies to enhance the financial and real performance of banks. The findings also suggest that both investors and owners should take into consideration the governance indicators while evaluating banks’ performance by using accounting, market-based, efficiency and productivity measures. Originality/value This research adds to the vast body of existing knowledge about the effectiveness of corporate governance by investigating how the different dimensions of corporate governance and gender diversity influence bank performance in a developing country, namely, Pakistan. Further, this study elaborates the domestic rules/regulations, governance theories and governance framework and practices and tries to link the empirical findings with them for better understanding the role of governance in determining the performance of the banking sector of Pakistan.
