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...

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...

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 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...
