Lead Directorship, Corporate Governance, And Firm Performance
This dissertation empirically explores the role of the lead directorship in the corporate governance system and strives to empirically examine the association between the lead directorship and firm performance. I measure firm performance by three empirical proxies: Tobin's Q, returns on assets (ROA) and stock returns. I explore the research question on the relationship between lead directorship and firm performance in both cross-sectional and inter-temporal contexts. The sample consists of S & P 500 firms from 2001 to 2004 that have all the required financial, stock returns, and other relevant information. Overall, the empirical results of both cross-sectional and inter-temporal analyses indicate a positive association between lead directorship and firm performance.
