Cet article analyse la relation entre l’inflation et les contraintes de crédit dansun modèle à générations imbriquées. On montre qu’une inflation positive peut contribuerà diminuer les contraintes de crédit, et que cet effet justifie une cible d’inflationpositive à long terme, sans hypothèse de rigidités nominales ou d’erreursd’anticipations. Dans un environnement non ricardien standard, qui est un modèleà générations imbriquées, on montre que les autorités monétaires peuvent conduireà un niveau de production optimal grâce à une inflation positive.This paper explores the relationship between credit constraints and inflation. It is shown that a small positive inflation can alleviate credit constraints and that this effect can justify a positive long run inflation target for central banks without any assumption concerning nominal rigidities. In a standard non-ricardian setting, which is an overlapping generation framework, I prove that monetary authorities can induce the optimal level of the real interest rate and hence the optimal level of production thanks to a positive long run inflation rate
