dc.description.abstract Most corporate governance research focusses on prescriptive measures of governance quality (e.g., board composition, attributes) and their association with measures of firm performance but neglects the dynamic nature of governance choices that impinge on firm value. In Chapter 1, I introduce a top-down approach for evaluating board effectiveness in a dynamic context focusing on the empirical outcomes of the decisions they make. A Principal Component Analysis is employed to construct an index of governance quality capturing six key aspects of board responsibilities. In Chapter 2, I turn to examine whether firms’ corporate governance quality can positively influence their stock returns and operating performance using the newly developed index that accounts for the dynamic nature of internal governance choices. By constructing decile portfolios of firms based on this measure of governance quality, I show that portfolios of firms with better governance quality outperform firms within the lower governance quality portfolios. Specifically, zero-investment strategies that buy HQ portfolios (highest governance quality) and short LQ portfolios (weakest governance quality) generate 3.9% and 3.2% returns for equally- and value-weighted portfolios, respectively. Finally, in Chapter 3, I follow a similar approach to that developed in the first two chapters to construct a dynamic governance quality index for a sample of public companies from 16 European countries. Comparing the returns of the portfolios based on this index reveals that European companies with higher governance quality (HQ portfolio) generally outperform their peers which possess a lower quality of governance (LQ portfolio). The findings also show that firm level governance can be affected by country-level elements such as legal and institutional structures. en
