We analyze dynamic trading by an activist investor who can expend costly effort to affect firm value. We obtain the equilibrium in closed form for a general activism technology, including both binary and continuous outcomes. Variation in parameters can produce either positive or negative...

The coskewness-cokurtosis pricing model is equivalent to there not being any return for which the alpha is positive and for which the residual risk has positive coskewness and negative cokurtosis with the market. Such returns would be extremely attractive to investors with...

We test the recent Fama-French five-factor model and Hou-Xue-Zhang four-factor model using test assets from Fama-MacBeth regressions, which are pure plays on particular characteristics or covariances. Our tests resolve the errors-in-variable bias in Fama-MacBeth regressions with estimated betas....

We provide a theoretical rationale for dealer objections to ex-post transparency in corporate bond and other OTC markets: Disclosure of the terms of a transaction conveys information possessed by the dealer about the asset quality and reduces the dealer's rents when she disposes of the inventory...

Mediator proposals can accelerate agreement and increase welfare even if the mediator is entirely uninformed. We demonstrate this by adding random mediation to the Cramton (1992) bargaining model. Mediation increases welfare by pooling types, which reduces signaling costs. When mediation is...

We solve a dynamic Kyle model in which the large investor's private information concerns her plans for taking an active role in governance. We show that once a block has been created, its continued existence is jeopardized by an increase in the liquidity of the firm's stock. Greater liquidity...

We derive the effect of plausible deniability on asset risk premia in a dynamic setting with correlated firm values, systematic risk, and risk-averse investors. Firms optimally exercise American disclosure options, which are more valuable due to the possibility that other correlated firms may...

Returns to pure play strategies, estimated as Fama-MacBeth slope coefficients on standardized size, value and momentum characteristics, have positive and significant four factor alphas. The mispricing of these characteristics-based strategies by the four factor model is due in part, but not...

The investment boundaries defined by Grenadier (2002) for an oligopoly investment game determine equilibria in open loop strategies. As closed loop strategies, they are not equilibria, because any firm by investing sooner can preempt the investments of other firms and expropriate the growth...

This paper studies the effect of clustering of liquidity trades on intraday patterns of volatility and market depth when private information is long-lived. The assumption of long-lived information allows us to distinguish between the patterns of information arrival and information use. Our...
