Due to the increasing roles of bank governance after the Global Financial Crisis, Basel III gives great emphasis on
the role of the board of directors in ensuring a long‐term survivability of the banking industry. This study aims to examine
the relationship between board structures, board monitoring and board diversity towards the efficiency of selected
commercial banks in ASEAN5 from 1998 to 2012. This study focuses on the directors’ characteristics and diversity, which
are essential elements of a sound corporate governance framework. Ultimately, this study seeks to develop a model of
corporate governance that can contribute to a superior banks’ performance in this region. The Data Envelopment Analysis
(DEA) model will be employed to estimate the profit efficiency scores of the selected commercial banks. The profit
efficiency score is a better measure of bank’s performance than financial ratios because it takes into consideration the
utilization of inputs in achieving a given level of profit. Besides, this study will employ panel data estimation based on Tobit
Regression and Structural Equation Modeling to investigate the relationship between board structures, monitoring and
diversity towards the efficiency of commercial banks in ASEAN5
