The Impact of the Board of Directors’ Size on the Bank’s Performance: Evidence from Turkey

Abstract

The present study investigates the impact of board of directors’ size on bank performance on a sample of 12 banks’ data that were involved in the Istanbul Stock Exchange (ISE) over the period 2005-2010. We mostly used the methods of regression and correlation in conducting the analyses of the research. The findings of the conducted analyses show negative and statistically significant results between such accounting-based performance indicators as Return on Assets (ROA) along with Return on Equity (ROE) and the banks’ board of directors’ size. The research also reveals the evidence of negative and statistically non-significant results between Tobin's Q as a market-based performance indicator and boards’ size. At the same time the research identifies positive relationship between ROA and ROE with banks’ "Free Float Ratio”, whereas on the contrary, the relationship between ROA and ROE with "Number of Employees per Branch and Risk" is negative.
