Système financier dualiste et impacts des politiques financières : essai de modélisation


  • Tanimoune, Nasser Ary

    (Université d’Ottawa)


The aim of this paper is to analyse according to neo-structuralists (in particular Van Wijnbergen, 1983) the impacts of financial policies such as the rise of the deposit interest rate on loanable funds in a dualist financial system. The model highlights the importance of the activism of banks concerning the financing of the economy and allows to explain the excess of liquidity of many banks in West Africa Economic and Monetary Union after the financial reforms. Cet article analyse l’impact d’une hausse du taux d’intérêt créditeur sur la distribution des crédits bancaires dans un environnement financier dualiste. Il s’inscrit dans le prolongement de la thèse développée par les néostructuralistes, notamment Van Wijnbergen (1983), selon laquelle dans les pays en développement une politique financière doit prendre en compte l’importance relative de toutes les structures de financement. Le principal résultat est la mise en évidence de l’activisme des banques dans le financement global d’une économie à système financier dualiste. Il permet d’expliquer l’excès de liquidité qui caractérise de nombreuses banques dans la Zone franc ouest africaine depuis le début des années quatre-vingt-dix.
