Large blocks of stock play an important role in many studies of corporate governance and finance. Despite this important role, there is no standardized data set for these blocks, and the best available data source, Compact Disclosure, has many mistakes and biases. In this paper, we document...

Large shareholders may play an important role for firm performance and policies, but identifying this empirically presents a challenge due to the endogeneity of ownership structures. We develop and test an empirical framework which allows us to separate selection from treatment effects of large...

From 1988 to 2003, the average change in managerial ownership is significantly negative every year for American firms. We find that managers are more likely to significantly decrease their ownership when their firms are performing well and more likely to increase their ownership when their firms...

We examine the determinants of appointments of outside CEOs to boards and how these appointments impact the appointing companies. We find that CEOs are most likely to join boards of large established firms that are geographically close, pursue similar financial and investment policies, and have...

We report evidence that the co-movements of index options and index futures quotes differ sharply from perfect correlation in periods with option trades. In half-hour intervals with (without) option trades 25% (12%) of call option quote changes have either the opposite sign or are larger in...

I analyze the role of executive compensation in corporate governance. As proxies for corporate governance, I use board size, board independence, CEO-chair duality, institutional ownership concentration, CEO tenure, and an index of shareholder rights. The results from a broad cross-section of...

We develop an empirical framework that allows us to analyze the effects of heterogeneity across large shareholders, and we construct a new blockholder-firm panel data set in which we can track all unique blockholders among large U.S. public firms. We find statistically significant and...

From 1988 to 2003, the average change in managerial ownership is significantly negative every year for American firms. The probability of large decreases in ownership is strongly increasing in contemporaneous and past stock returns but the probability of large increases in ownership through...

Eleven percent of the largest public U.S. firms are headed by the CEO who founded the firm. Founder-CEO firms differ systematically from successor-CEO firms with respect to firm valuation, investment behavior, and stock market performance. Founder-CEO firms invest more in Ramp;D, have higher...
