Abstract:

This paper formalizes a macroeconomic model of inefficient credit cycles in a continuous time dynamic contract setting. We show that under moral hazard, the optimal competitive contract between households and entrepreneurs results in socially excessive debt expansion during booms and insufficient credit provision during recessions. Inefficient credit fluctuations generate inefficient waves of investments. Because the inefficiencies flip signs over the business cycle, prudential regulations may exacerbate under-borrowing in recessions, and stimulus measures may aggravate overborrowing in booms, sowing the seeds of the next crisis. A well-designed intervention admits a state-dependent, sufficient-statistic-like representation in terms of measurable variables.
