This paper studies the interaction between monetary and fiscal authorities while investors are coordinating on a speculative attack. The authorities want to achieve specific targets for output and inflation but also to avoid a regime change (i.e. sovereign default). They use the traditional...

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...

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 studies defense policies in a global-game model of speculative currency attacks. Although the signaling role of policy interventions sustains multiple equilibria, a number of novel predictions emerge which are robust across all equilibria. (i) The central bank intervenses by raising...

This paper examines the ability of a policy maker to control equilibrium outcomes in a global coordination game; applications include currency attacks, bank runs, and debt crises. A unique equilibrium is known to survive when the policy is exogenously fixed. We show that, by conveying...

Global games of regime change–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 extend the...

Global games with endogenous information often exhibit multiple equilibria. In this paper we show how one can nevertheless identify useful predictions that are robust across all equilibria and that could not have been delivered in the common-knowledge counterparts of these games. Our analysis is...

Theoretical Computer Science classically aimed to develop a mathematical understanding of capabilities and limits of traditional computing architecture (Boole, von Neuman, Turing, Church, Godel), investigating in computability, complexity theory and algorithmics. Now it seems more natural to...

Population games are stochastic processes which explicitly model Nash's (1950) mass action interpretation of Nash equilibrium. The mass action interpretation envisions a population of players for each position in the game, and that players are randomly matched for play. The hope is that the...
