We develop a dynamic model of liquidity provision, in which hedgers can trade multiple risky assets with arbitrageurs. We compute the equilibrium in closed form when arbitrageurs' utility over consumption is logarithmic or risk-neutral with a non-negativity constraint. Liquidity is increasing in...

We develop a model of the gambler's fallacy - the mistaken belief that random sequences should exhibit systematic reversals. We show that an individual who holds this belief and observes a sequence of signals can exaggerate the magnitude of changes in an underlying state but underestimate their...

We propose a rational theory of momentum and reversal based on delegated portfolio management. Flows between investment funds are triggered by changes in fund managers' e±ciency, which investors either observe directly or infer from past performance. Momentum arises if fund °ows exhibit...

In this paper we survey the theoretical and empirical literature on market liquidity. We organize both literatures around three basic questions: (a) how to measure illiquidity, (b) how illiquidity relates to underlying market imperfections and other asset characteristics, and (c) how illiquidity...

We analyze how asymmetric information and imperfect competition a®ect liquidity and asset prices. Our model has three periods: agents are identical in the ¯rst, become heterogeneous and trade in the second, and consume asset payo®s in the third. We show that asymmetric information in the...

Polarization of opinions after public announcement is widely observed, but often considered to be inconsistent with Bayesian learning. I show that this is not the case in environments where higher-order expectations play a role. I characterize informational structures where public announcement...

We model trading and information diffusion in OTC markets, when dealers can engage in many bilateral transactions at the same time. We show that information diffusion is effective, but not efficient. While each bilateral price partially reveals all dealers' private information after a single...
