In a Kyle (1985) model, the sign of the correlation between a firm's debt and equity returns is the same as the sign of the cross-market Kyle's lambda. The sign is positive (negative) if private information concerns the mean (risk) of the firm's assets. We show empirically that information...

Is greater trading liquidity good or bad for corporate governance? We address this question both theoretically and empirically. We solve a model consisting of an optimal IPO followed by a dynamic Kyle market in which the large investor's private information concerns her own plans for taking an...

Limit-order markets and floor exchanges are analyzed, assuming an informed trader and discretionary liquidity traders use market orders and can either submit block orders or work their demands as a series of small orders. By working their demands, large market-order traders pool with small...

We analyze competition among informed traders in the continuous-time Kyle (1985) model, as Foster and Viswanathan (1996) do in discrete time. We confirm the conjecture of Holden and Subrahmanyam (1992) that there is no linear equilibrium when traders have identical information. When traders'...

Portfolio turnpike theorems show that if preferences at large wealth levels are similar to power utility, then the investment strategy converges to the power utility strategy as the horizon increases. We state and prove two simple and general portfolio turnpike theorems. Unlike existing...

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...

We propose and estimate a model of endogenous informed trading that is a hybrid of the PIN and Kyle models. When an informed trader trades optimally, both returns and order flows are needed to identify information asymmetry parameters. Empirical relationships between parameter estimates and...

Mutual funds seek alpha, but coskewness is also an important performance attribute. Alpha and coskewness relative to the market are negatively correlated in theory, so funds may generate undesirable coskewness in the pursuit of alpha. Empirically, the tradeoff exists for mutual funds and is...

We derive the optimal portfolio for an investor with increasing relative risk aversion in a complete continuous-time securities market. The IRRA assumption helps to mitigate the criticism of constant relative risk aversion that it implies an unreasonably large aversion to large gambles, given...

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...
