This paper studies relationships between the local determinacy of a stationary equilibrium in the perfect foresight dynamics, and its local stability in dynamics arising from econometric learning procedures. There is no clear links in linear scalar economieds where agents forecast only one...

The paper discusses the concept of "expectational market failures" ; it attempts to assess the scope for Government intervention aiming at stabilizing economic agents' expectations. The Rational Expectations Hypothesis, "evolutive" and "eductive" learning credibility, "indicative Planning",...

The paper examines within a unified methodology expectational coordination in a series of economic models. The methodology views rational expectations equilibria as reasonable predictors whenever they can be derived from more basic Common Knowledge hypothesis. The paper successively considers a...

We consider Rational Expectations Equilibria in infinite horizon models in which equilibrium to-day depends upon the past, yesterday, and the future, to-morrow. We focus attention on a category of ''Sunspot Equilibria'', (` la Davila) that have a finite support and trigger a quasi-cyclic...

In this paper we study expectations coordination on a deterministic 2-cycle by an "eductive" approach in which agents are concerned with forecasting the forecasts of others. This approach is grounded in some Common Knowledge assumption. We show that eductively stable 2-cycles exit. We also show...

In this paper we study expectations coordination on the stationary state in a one dimensional economy. We allow for two sources of heterogeneity : the first concerns the fundamentals of the economy, the second the adaptive learning rules. Specifically we consider heterogeneous adaptive learning...
