Financial Crisis Resolution

Abstract

Dans cette étude, l’auteur utilise une version dynamique du modèle d’intermédiation financière de Holmstrom et Tirole. Il montre que les équilibres concurrentiels ne sont pas soumis à une contrainte d’efficience quand l’économie subit une crise financière. Sous l’effet d’une externalité pécuniaire, le désir des banques d’accumuler des fonds propres au fil du temps aggrave, lors de la crise financière, la rareté des capitaux en provenance d’investisseurs disposant d’un avantage informationnel. L’auteur fait ressortir que, pour un planificateur central soumis à une contrainte, il est avantageux d’introduire un écart permanent entre le taux de rémunération des dépôts et le taux marginal de transformation de l’économie. Cette différence améliore l’accès des emprunteurs au crédit en période de crise financière, car elle rend l’offre de services d’intermédiation plus attrayante pour les banques. L’auteur propose une simple application d’une allocation sous contrainte d’efficience qui limite la taille des banques.

This paper studies a dynamic version of the Holmstrom-Tirole model of intermediated finance. I show that competitive equilibria are not constrained efficient when the economy experiences a financial crisis. A pecuniary externality entails that banks’ desire to accumulate capital over time aggravates the scarcity of informed capital during the financial crisis. I show that a constrained social planner finds it beneficial to introduce a permanent wedge between the deposit rate and the economy’s marginal rate of transformation. The wedge improves borrowers’ access to finance during a financial crisis by strengthening banks’ incentives to provide intermediation services. I propose a simple implementation of the constrained-efficient allocation that limits bank size.
