L'apport du modèle de concurrence monopolistique à l'économie bancaire

  • André Grimaud
  • Jean-Charles Rochet

[eng] The monopolistic competition model and banking theory We show that the Salop [1979] monopolistic competition model can reveal very useful in banking theory. We first recall several of its recent applications to the modeling of competition between bank branches (Chiappori et ali [1992], Grimaud-Rochet [1993a], Matutes-Padilla [1991]). Then we show that it can provide as well simple and robust specifications for the monetary and financial part of a macro-model with an explicit description of deposit, credit and asset markets. [fre] L'apport du modèle de concurrence monopolistique à l'économie bancaire Le modèle de concurrence monopolistique de Salop [1979] est très utilisé en économie industrielle. Il peut s'avérer également très utile en économie bancaire. Après avoir rappelé quelques applications récentes de ce modèle à la formalisation de la concurrence entre réseaux bancaires (Chiappori et al. [1992], Grimaud-Rochet [1993a], Matutes-Padilla [1991]), nous montrons qu'il peut fournir aussi des spécifications simples et solides à la partie monétaire et financière d'un modèle macro-économique où sont décrits explicitement les marchés des dépôts, des crédits et des titres financiers.
