Challenges in the Measuring of Comparative Corporate Governance: A Review of the Main Indices

Purpose – This chapter discusses the role that indices of corporate governance have had in comparative corporate governance research. Design/Methodology/Approach – The authors begin with a short discussion of what corporate governance is and its main debates. Then, the authors review the main indices (which are also summarized in Table 1), highlighting their strengths and limitations as well as describing some of the findings that emanate from them. Then, the authors discuss the methodological and conceptual assumptions of corporate governance indices that may compromise their construct validity. The authors conclude with some encouraging suggestions for key methodological and research design issues to take into account in future comparative corporate governance. Findings – Many methodological issues in the measuring and analysis of (comparative) corporate governance remain to be solved. First, although corporate governance practices have a direct effect on some of the firms’ strategic decisions, they may only have an indirect effect on firm performance. Second, it is possible that, after all, causality goes the other way around, i.e., the firm performance explains the adoption of certain governance practices. Third, there are also important challenges in measuring firm financial performance as well as measuring and comparing corporate governance effectiveness between firms from different governance settings. Originality/Value – This is one of the first chapter to give an overview of the most current corporate governance indices, both academic and commercial, to discuss their underlying assumptions and limitations, and, finally, to provide specific directions for future research regarding comparative corporate governance.
