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...

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...

This paper analyzes conditions for strong rationality of the equilibrium in a linear/Gaussian model of a competitive commodity market, where firms are differentially informed about costs of production and the precision of private information is endogenously acquired. A Rational Expectations...

This paper studies the effect of asymmetric information on equilibrium stability in a class of linear models where the actual state depends on the forecasts about it. Stability is deffined by the so-called eductive criterion which relies on common knowledge of rationality. The main result is...
