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...

At the end of 1997, the foreign companies listed in the U.S. have a Tobin's q ratio that exceeds by 16.5% the q ratio of firms from the same country that are not listed in the U.S. The valuation difference is statistically significant and largest for exchange-listed firms, where it reaches 37%....

Standard theories of corporate ownership assume that because markets are efficient, insiders ultimately bear agency costs and therefore have a strong incentive to minimize conflicts of interest with outside investors. We show that if equity is overvalued, however, mispricing offsets agency costs...

The bulk of corporate governance theory examines the agency problems that arise from two extreme ownership structures: 100 percent small shareholders or one large, controlling owner combined with small shareholders. In this paper, we question the empirical validity of this dichotomy. In fact,...

We present a mechanism based on managerial incentives through which common ownership affects product market outcomes. Firm-level variation in common ownership causes variation in managerial incentives and productivity across firms, which leads to intra-industry and intra-firm cross-market...

We use machine learning to analyze minute-by-minute Bloomberg online status data and study how the effort provision of top executives in public corporations affects firm value. While executives likely spend most of their time doing other activities, Bloomberg usage data allows us to characterize...

We show that Tobin's q, as proxied by the ratio of the firm's market value to its book value, increases with the firm's systematic equity risk and falls with the firm's unsystematic equity risk. Further, an increase in the firm's total equity risk is associated with a fall in q. The negative...

Using more than 50,000 firm-years from 1988 to 2015, we show that the empirical relation between a firm's Tobin's q and managerial ownership is systematically negative. When we restrict our sample to larger firms as in the prior literature, our findings are consistent with the literature,...

CEOs have a potential conflict of interest when their company is acquired: they can bargain to be retained by the acquirer and for private benefits rather than for a higher premium to be paid to the shareholders. We investigate the determinants of target CEO retention by the acquirer and whether...

We investigate whether the value of large banks, defined as banks with assets in excess of the Dodd-Frank threshold for enhanced supervision, increases with the size of their assets using Tobin's q and market-to-book as our valuation measures. Many argue that large banks receive subsidies from...
