I study a general equilibrium model in which investors face endowment risk and trade two correlated assets; one asset is traded on a liquid market whereas the other is traded on an illiquid over-the-counter (OTC) market. Endowment shocks not only make prices drop, they also make the OTC asset...

We identify long-lived pricing errors through a model in which inattentive investors arrive stochastically to trade. The model’s parameters are structurally estimated using daily NYSE market-maker inventories, retail order flows, and prices. The estimated model fits empirical variances,...

We develop an equilibrium model of commodity spot and futures markets in which commodity production, consumption, and speculation are endogenously determined. Speculators facilitate hedging by the commodity suppliers. The entry of new speculators thus increases the supply of the commodity and...

We explore the effects of information propagation in a centralized financialmarket. Specifically, we embed search frictions within the Grossman andStiglitz (1980) framework, relying on information percolation as modeled inDuffie, Malamud, and Manso (2009). First, we show that information...

Our purpose is to show how large difference of beliefs induced by fear of crashesis amenable to large and persistent price responses to contemporaneous shocks. Weconstruct a pure exchange economy populated by two agents who estimate strictlydifferent models regarding the fundamental. In...

A flat Securities Market Line is not evidence against the CAPM. In a rational-expectations economy in which markets are not informationally efficient, the CAPM holds but is rejected empirically (Type I Error). There exists an information gap between the empiricist and the average investor who...

Regardless of whether the CAPM is rejected for valid reasons or by mistake, a single long-short portfolio will always explain, together with the market, 100% of the cross- sectional variation in returns. Yet, this portfolio, which we coin the “Low-Minus-High (LMH) portfolio,” need not proxy...

A pervasive empirical finding is that mutual fund managers do not maintain their performance. In this paper, I show that social interactions can explain this fact. To do so, I allow a “crowd” of managers to meet at random times and exchange ideas within a rational-expectations equilibrium...
