Governance Effect of Board of Directors on Banking Performance: Evidence From Tunisia

Abstract

The research tried to assess the impact of board characteristics on Tunisian bank's performance. The empirical study is based on a sample of 10 commercial banks during the period 2008-2017. Firstly, we proceed to estimate the impact of board characteristics on bank performance measured by Return on Assets (ROA) and Return on Equities (ROE) ratios. The estimation results achieved have positive and negative effects on the economic and financial bank's profitability. Hence, on the one hand, the estimate test gives a positive impact of ratio Market to book and the ratio Interest / Commissions in case of economic performance (VIC). On the other hand, these two ratios have a negative impact on performance measured by the ROE and ROA. Regarding the board and bank size, the estimate test gives a negative impact on economic profitability and a positive impact on financial profitability.
