Abstract

L'article vise à opposer l'analyse macroéconomique moderne à une macroéconomie non walrasienne ou évolutionnaire. Ce débat, qui revient sur le devant de la scène à chaque grande crise économique, concerne la nature des problèmes de coordination et les moyens de les résoudre. Alors que les modèles de la macroéconomie moderne décrivent les comportements d'optimisation inter-temporelle de consommateurs parfaitement adaptés à leur environnement et des marchés soldés, la macroéconomie évolutionnaire met l'accent sur les déséquilibres du marché qui nécessitent des comportements adaptatifs. Ce contraste affecte la politique monétaire et budgétaire ainsi que la nature des réformes structurelles à mener. Il concerne également le type de modélisation à développer.
