Corporate governance of banks: A survey

Abstract

This paper reviews the empirical literature on the corporate governance of banks. We start by highlighting the main differences between banks and nonfinancial firms and focus on three characteristics that make banks special: (i) regulation, (ii) the capital structure of banks, and (iii) the complexity and opacity of their business and structure. Next, we discuss the characteristics of corporate governance in banks and how they differ from the governance of nonfinancial firms. We then review the evidence on three governance mechanisms: (i) boards, (ii) ownership structures, and (iii) executive compensation. Our review suggests that some of the empirical regularities found in the literature on corporate governance of nonfinancial institutions, such as the positive (negative) association between board independence (size) and performance, do not hold for banks. Also, existing work provides no conclusive results regarding the relationship between different governance mechanisms and various measures for banks' performance. We discuss potential explanations for these mixed results.
