How damaging is competition between bank regulators? This paper develops a model in which both banks' risk profile and their access to wholesale funding are endogenous. Regulators weigh not only welfare, but also the number of banks under their supervision. Simulations indicate that the gains...

This paper analyzes the trade-off between financial stability and credit rationing that arises when increasing capital requirements. It extends the Stiglitz-Weiss model of credit rationing to allow for bank default. Bank capital structure then matters for lending incentives. With default and...

The model of Stiglitz and Weiss ( American Economic Review , 1981, 71(3)) is the seminal analytical work on credit rationing. However, in a recent paper, Arnold and Riley ( American Economic Review , 2009, 99(5)) claim that the distributional assumption on which that model.s main result depends...

If monetary policy is to aim also at financial stability, how would it change? To analyze this question, this paper develops a general-form, axiomatic framework. Financial stability objectives are shown to make a monetary authority more aggressive. By that we mean that in reaction to negative...

This paper models a financial sector in which there is a feedback between individual bank risk and aggregate funding market problems. Greater individual risk taking worsens adverse selection problems on the market. But adverse selection premia on that market push up bank risk taking, leading to...

This paper shows that a rate hike has countervailing effects on banks' risk appetite. It reduces risk when the debt burden of the banking sector is modest. We model a regulator whose trade-off between bank risk and credit supply is derived from a welfare function. We show that the regulator...
