This dissertation is composed by two essays that explore corporate governance issues in S&P firms. The first essay examines changes in corporate governance after a firm gets added to the S&P 500 index? Using firms added from 1994 to 2007, this paper examines how governance mechanisms change for these firms. Specifically, I look at both the overall governance and details on how each mechanism changes. I find that governance improves after being added to the index. Controlling for firm size, leverage, prior firm performance, and growth opportunities, the market reacts positively to governance improvements as a whole. In addition, changes in governance are positively associated with changes in operating performance. In the second essay, the departure of a CEO often raises questions about who will replace him/her. This study examines the homogeneity/heterogeneity nature of the internal labor market using a novel measure, a heterogeneity index, which captures the concentration of executive compensation levels. I find that a more homogeneous internal labor market is associated with (1) a greater likelihood of an internal replacement, (2) a higher probability of a CEO turnover, and (3) a bigger tournament prize. In addition, the negative performance-turnover relationship is strengthened by a more homogeneous internal labor market. The heterogeneity index seems to proxy for internal labor market competition.
