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...

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...

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...

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...

This paper develops a game theory model to analyze the optimal structure of the Lender of Last Resort in Europe. When depositors are imperfectly informed, the indifference to international transmission displayed by national authorities has value. A centralized authority, because it internalizes...

The global financial crisis highlighted that the financial system can be most vulnerable when it seems most stable. This paper models non-linear dynamics in banking. Small shocks can lead from an equilibrium with few bank defaults straight to a full freeze. The mechanism is based on...

If monetary policy is to aim also at financial stability, how would it change? To analyze this question, this paper develops a general-form framework. Financial stability objectives are shown to make monetary policy more aggressive: in reaction to negative shocks, cuts are deeper but...

The paper examines the implementation of macro-prudential policy. Given the coordination, flow of information, analysis, and communication required, macro-prudential frameworks will have weaknesses that make it hard to implement policy. And dealing with the political economy is also likely to be...
