Un modèle macroéconomique de chômage avec concurrence imparfaite et anticipations rationnelles

  • Bénassy, Jean-Pascal

    (CEPREMAP)

Registered author(s):

    We construct in this article a macroeconomic model of unemployment with imperfect competition (based on objective demand curves) and rational expectations, and we study its characteristics, in order notably to compare them with those of usual Keynesian and Walrasian macroeconomic models. We first see that the model's equilibrium displays properties of inefficiency and underemployment of resources (notably labor) which are very similar to those of a Keynesian equilibrium with rigid prices and general excess supply. Inspite of this a proportional increase of the quantity of money is neutral, just as in a Walrasian model. We finally find that the normative prescriptions of the model concerning public spending are neither Keynesian nor Walrasian. Nous construisons dans cet article un modèle macroéconomique de chômage avec concurrence imparfaite (basée sur des courbes de demande objectives) et anticipations rationnelles, et nous en étudions les caractéristiques, dans le but notamment de les comparer à celles des modèles macroéconomiques keynésiens et walrasiens habituels. On voit tout d’abord que l’équilibre du modèle a des propriétés d’inefficacité et de sous-emploi des ressources (notamment du travail) très semblables à celles d’un équilibre keynésien à prix rigides et excès d’offre généralisé. Malgré cela un accroissement proportionnel de la quantité de monnaie est neutre, tout comme dans un modèle walrasien. Finalement on trouve que les recommandations normatives quant aux dépenses publiques ne sont ni keynésiennes, ni walrasiennes.
