We examine the connection between two stability concepts of rational expectations equilibria: expectational stability, based on the convergence of iterations of expectations, and strong rationality, based on uniqueness of the rationalizable solutions of an associated game with restrictions on...

This paper examines justifications of the rational expectations hypothesis that rely on the analysis of the agents' mental forecasting ("educing") activity which involves "forecasting the forecasts" of others etc. The corresponding eductive learning stability concept, based on the game...

The paper provides a brief review of existing results on the transmission of information through prices, when the revealing equilibria have to fit a criterion of "eductive stability". The work under review often suggests that, at odds with the "efficient market hypothesis", the plausibility of...

This working paper gathers two texts. The first one evokes the personality and work of Jules Dupuit, whose famous 1844's contribution is generally viewed as the founding piece of public cost benefit analysis. The second paper presents the content of the opening conference of the "Journ ées de...

This paper compares the most significant expectational stability criteria that have been used to assess the plausibility of perfect foresight trajectories in forward-looking dynamical systems: determinacy of trajectories, absence of neighbour sunspot trajectories, and convergence of "evolutive"...

We examine local strong rationality (LSR) in multivariate models with both forward-looking expectations and predetermined variables. Given hypothetical common knowledge restrictions that the dynamics will be close to those of a specified minimal state variable solution, we obtain eductive...
