This paper shows how expectations-driven contagion of currency crises can arise even if the currency market has a unique equilibrium when viewed in isolation. The model of Morris and Shin (1998) is extended to allow speculators to trade in a second currency market. If speculators believe that a...

We propose a theory of unsecured debt that is based on the existence of private information about a person's type and on the fact that some debtors have the incentive to forego bankruptcy in order to signal their type. The theory formalizes the idea that the type of a person is relevant to...

Asset prices display high covariance relative to the covariance of their payoffs. (Pindyck and Rotemberg, 1993; Barberis, Shleifer and Wurgler, 2002) Many take this ‘excess covariance’ to be evidence of investor irrationality. This model reconciles the high covariance with a rational...

We augment a standard global coordination game along the lines of Morris and Shin (1998) by an asset market where prices are determined in a noisy Rational Expectations Equilibrium. We study the implications of information aggregation through prices for equilibrium selection arguments in global...

This paper examines how the dynamics of information influences the dynamics of coordination in an environment with strategic complementarities and heterogeneous expectations. We consider a simple dynamic global game of regime change, in which the status quo is abandoned when a sufficiently large...

I analyze the implications of moral hazard in dynamic economy with production. In particular, I add agency frictions to a benchmark stochastic growth model, by assuming that firms observe output but hours worked and productivity are unobservable. I cast the problem as a continuous time principal...
