We extend Kyle's (1985) model of insider trading to the case where noise trading volatility follows a general stochastic process. We determine conditions under which, in equilibrium, price impact and price volatility are both stochastic, driven by shocks to uninformed volume even though the...

We examine the role of strategic communication in public short selling campaigns by hedge funds. Such campaigns are associated with abnormal returns for targets of approximately -7% as well as changes in the behavior of stakeholders (e.g., other short sellers). The effects are driven by...

This paper investigates the effects of college tuition on student debt and human capital accumulation. We exploit data from a random sample of undergraduate students in the United States and implement a research design that instruments for tuition with relatively large changes to the tuition of...

This paper proposes that computational complexity generates noise. The same asset is often held for completely different reasons by many funds following a wide variety of threshold-based trading rules. Under these conditions, we show it can be computationally infeasible to predict how these...

We analyze hedge fund performance before “birth” (i.e., the date on which a fund begins to self-report to commercial databases) and after “death” (i.e., the date on which a fund ceases to self-report to commercial databases). We find that funds initiate reporting after an extended period...

Abstract We study the effects of investor disagreement on informed trading by activist investors using high-frequency disagreement data derived from the investor social network StockTwits. Greater investor disagreement leads to more trading activity on the subsequent day by privately informed...

This is the first comprehensive study of the distribution of voting rights to shareholders. Only those owning stock on the record date may vote. Firms, however, reveal that date after the fact 91% of the time. With controversial votes, firms are more likely to do the opposite, and this is...

When a proxy contest is looming, the rate at which CEOs exercise options in order to sell (hold) the resulting shares slows down by 80% (accelerates by 60%), consistent with their desire to maintain or strengthen voting rights when facing challenges. Such deviations are closely aligned with...
