I study coordination games with incomplete public and private information and relate
equilibrium convergence to convergence of higher-order beliefs. As the players' signals
become more and more precise, the equilibrium manifold converges to the ...

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

Abstract We explore how optimal information choices change the predictions of strategic
models. When a large number of agents play a game with strategic complementarity,
information choices exhibit complementarity as well: if an agent wants to do what others ...

We develop a stylized currency crises model with heterogeneous information among

Abstract I analyze the business cycle and welfare effects of public information disclosures in
a model of monopolistic competition among heterogeneously informed firms. Information
heterogeneity leads to potentially important delays in price adjustment and amplifies the ...
Abstract: This paper introduces signaling in a global game so as to examine the

Abstract I study the effects of a lack of common knowledge on nominal adjustment in a
dynamic price-setting game with incomplete information. In particular, I show how the speed

This paper examines the ability of a policy maker to control equilibrium outcomes in an

We characterize equilibria with endogenous debt constraints for a general equilibrium
economy with limited commitment in which the only consequence of default is losing the
ability to borrow in future periods. First, we show that equilibrium debt limits must satisfy a ...

Abstract Should central banks or other government agencies always commit to provide
timely and accurate information about economic fundamentals? The answer to this question
depends on the extent to which markets make efficient use of the available information. In ...
Pricing complementarities play a key role in determining the propagation of monetary
disturbances in sticky price models. We propose a procedure to infer the degree of firm-level
pricing complementarities in the context of a menu cost model of price adjustment using ...

Nominal price adjustment is studied in an environment with firm-specific and aggregate
shocks to economic fundamentals and incomplete, dispersed information. Firms update their
expectations about fundamentals based on their own cash flows (revenues and wages). ...

Abstract I study the welfare effects of a lack of common knowledge in a dynamic price-setting
