Abstract

We study the impact of capital regulation on the quality of the banking sector in the presence of heterogeneous banks. Closely related to Morrison and White (2005), we provide a general equilibrium framework with heterogeneous individuals that differ in their ability of successfully completing a risky investment project. In addition to the classical moral hazard problem, we identify an additional countervailing selection problem of a stricter capital regulation. More regulatory capital decreases the deposit rate and mitigates the severity of the moral hazard problem. This decrease in the deposit rate, however, comes at the cost of a worsening of the selection problem. We show that rising heterogeneity in the banking sector increases the allocation effect and thus, improves the selection among individuals.
