Global games emerged as an approach to equilibrium selection. For a general setting with supermodular payoffs unique selection of equilibrium has been obtained through iterative elimination of strictly dominated strategies. For the case of global games with strategic substitutes, uniqueness of...

We consider an economic model that features: 1. a continuum of agents 2. an aggregate state of the world over which agents have an infinitesimal influence. We first propose a review, based on work by Jara (2007), of the connections between the eductive viewpoint that puts emphasis on Strongly...

The concept of Rationalizability has been used in the last fifteen years to study stability of equilibria on models with continuum of players such as standard competitive markets, macroeconomic dynamics and currency attacks. However, Rationalizability has been formally defined in a general...

In a homogeneous product duopoly with concave revenue and convex costs we study a two stage game in which, first, firms engage simultaneously in capacity (production) and, after production levels are made public, there is sequential price competition in the second stage. Randomizing the order of...

We consider an economic model that features : 1. a continuum of agents 2. an aggregate state of the world over which agents have an infinitesimal influence. We first review the connections between the eductive viewpoint that puts emphasis for example on strongly rational expectations equilibrium...

This paper studies how the threat of a protest influences government spending. The government has to choose a policy to maximize its payoff, which depends on (1) the policy itself and (2) the protest's outcome. {Citizens observe the policy choice and a private signal before deciding...
