Abstract: [eng] Rational expectations and information revealed by prices : an introduction. Catherine Rouzaud. This paper is intended to introduce some recent studies on rational expectations in general equilibrium theory under asymmetric information. In order to clarify the basis of this literature, the first part recalls the fundamental concepts and limitations of the Arrow-Debreu model under uncertainty. The second presents the main result associated with the introduction of the rational expectations assumption into this theoretical framework, i.e. the possibility that agents with different initial information about the environment infer from the equilibrium prices the total information available in the economy. Some related problems are finally sketched out. [fre] thèse des anticipations rationnelles à l'intérieur de ce cadre théorique, à savoir la possibilité que les agents ayant différentes informations initiales au sujet de l'environnement infèrent des prix d'équilibre la totalité de l'information disponible dans l'économie. Elle esquisse en dernier lieu les problèmes qui s'y rapportent.
