Corporate governance and financial performance: Evidence from the Ghanian banking sector

Abstract

Due to widespread bank scandals and failures around the world, there has been renewed interest in the effect of corporate governance on bank performance. The majority of research concerning corporate governance and its effect on bank performance has been undertaken in developed countries and markets, particularly the USA and European Union but relatively little evidence is provided in Sub Saharan Africa, specifically, Ghana. This study investigates the effects of corporate governance on financial performance of Ghanaian universal banking companies during the period 2006- 2014. This study primarily employs relevant governance theories to investigate the relationship between corporate governance and bank performance. Multiple regression panel data analysis and other appropriate methods are the main tools of analysis in this study. The empirical investigation revealed a mixed set of results. The findings showed that board size, board composition, bank size and foreign ownership are positively but insignificantly related to profitability in terms of return on asset and return on equity, while board committees have a positive and statistically significant impact on financial performance which is consistent with the monitoring hypothesis of agency theory which argues that board committees are an important mechanism of corporate governance in Ghana which impact on bank performance. This study contributes to the increasing number of research studies on the link between bank performance and corporate governance. The lacked of clarity, mixed and permanent relationships provided, show that the association the association between bank performance and different corporate governance mechanisms is complex and dynamic optimal governance arrangements may differ from bank to bank in relation to governance characteristics.
