Financial Crisis Interventions

Abstract

L’auteur élabore un modèle d’une économie où le crédit bancaire soutient à la fois l’investissement productif et le lissage de la consommation individuelle face à un risque idiosyncrasique pesant sur les revenus. Le crédit qu’une banque peut octroyer est limité par ses capitaux propres. Lorsque, durant une crise financière, les autorités monétaires injectent des liquidités à l’appui des fonds propres bancaires, elles effectuent un arbitrage entre l’effet stimulant immédiat de cette mesure sur l’offre de crédit et les distorsions à long terme qui en résultent. L’auteur étalonne son modèle et montre qu’une injection d’argent frais dans les banques qui maximise le bien-être utilitaire moyen entraîne une redistribution de la richesse des plus pauvres vers les plus riches. Alors que les épargnants aisés profitent immédiatement d’un apport accru d’actifs sûrs, les emprunteurs et les épargnants moins nantis souffrent des distorsions à long terme.

This paper develops a model of an economy where bank credit supports both productive investment and individual consumption smoothing in the face of idiosyncratic income risk. Bank credit is constrained by bank equity capital. When policy-makers inject equity capital during financial crises, they trade off stimulating credit supply immediately against long-term distortions related to funding equity injections. I calibrate my model and show that the bank equity capital injection that maximizes average utilitarian welfare redistributes from the poor to the wealthy. While wealthy savers benefit immediately from an increased supply of safe assets, less affluent borrowers and savers suffer from long-term distortions.
