This paper proposes that equilibrium valuation is a powerful method to generate endogenous jumps in asset prices, which provides a structural alternative to traditional reduced-form specifications with exogenous discontinuities. We specify an economy with continuous consumption and dividend...

This paper studies quantitative implications of model economies that exhibit multiple equilibria. The goal is to assess two interrelated issues. First, do economies with multiple equilibria have falsifiable predictions? Second, is identification possible in economies that exhibit multiple...

A search-theoretic general equilibrium model of frictional unemployment is shown to be consistent with some of the key regularities of unemployment over the business cycle. In the model the return to a job moves stochastically. Agents can choose either to quit and search for a better job, or...

This paper investigates the dynamic behavior of an economy with multiple Nash equilibria. The first part of the paper analyzes an abstract game exhibiting multiple equilibria. A history dependent selection criterion is proposed which induces correlated behavior in equilibrium even though agents...

Fluctuations in the equilibrium rate of unemployment can only be understood within a theory of the natural or equilibrium rate. It is not enough to say that unemployment is the difference between supply and demand in the labor market, though of course it always will be. In equilibrium, no...

A central authority possessing tax and expenditure responsibilities can readily provide an efficient level of a public good. Absent a central authority, voluntary arrangements must replace coercive ones. Significant under-provision must be expected. International public goods are particularly...

Global games of regime change -- that is, coordination games of incomplete information in which a status quo is abandoned once a sufficiently large fraction of agents attacks it -- have been used to study crises phenomena such as currency attacks, bank runs, debt crises, and political change. We...

This paper examines the ability of a policy maker to control equilibrium outcomes in an environment where market participants play a coordination game with information heterogeneity. We consider defense policies against speculative currency attacks in a model where speculators observe the...

A large body of recent empirical work on inflation dynamics documents that current real variables (like unemployment or output gaps) have little explanatory power for future inflation. Motivated by these findings, I explore the properties of a wide class of models in which inflation expectations...

We design a laboratory experiment to investigate bilateral link formation in a setting where payoffs are pair-specific. Our link formation rule is decentralized and players can make link offers and counter-offers, as in a Beckerian marriage market. The game is designed in such a way that a...
