A Model of Moral-Hazard Credit Cycles

Abstract

This paper considers a simple model of credit cycles driven by moral hazard in financial intermediation. Financial agents or bankers must earn moral-hazard rents, but the cost of these rents can be efficiently spread over an agent’s entire career by promising large late-career rewards if the agent has a consistently successful record. Dynamic interactions among different generations of financial agents can create credit cycles with repeated booms and recessions. In recessions, a scarcity of trusted financial intermediaries limits investment and reduces employment. Under such conditions, taxing workers to subsidize bankers may increase employment enough to make the workers better off.
