We model the interaction between two economies where banks exhibit both adverse selection and moral hazard and bank regulators try to resolve these problems. We find that liberalising bank capital flows between economies reduces total welfare by reducing the average size and efficiency of the...

Deposit insurance schemes are becoming increasingly popular around the world and yet there is little understanding of how they should be designed and what their consequences are. In this paper we provide a new rationale for the provision of deposit insurance. We analyse a model in which agents...

We analyse a general equilibrium model in which there is both adverse selection of and moral hazard by banks. The regulator has several tools at her disposal to combat these problems. She can audit banks to learn their type prior to giving them a licence, she can audit them ex post to learn the...

We analyse a general equilibrium model in which there is both adverse selection of and moral hazard by banks. The regulator has two tools at her disposal to combat these problems - she can audit banks to learn their type prior to giving them a licence, and she can impose capital adequacy...

Existing studies suggest that systemic crises may arise because banks either hold correlated assets, or are connected by interbank lending. This paper shows that common regulation is also a conduit for interbank contagion. One bank’s failure may undermine confidence in the banking...

We analyze the desirability of level playing fields in international financial regulation. In general, level playing fields impose the standards of the weakest regulator upon the best-regulated economies. However, they may be desirable when capital is mobile because they counter a cherry-picking...

We analyze a general equilibrium model in which there is both adverse selection of, and moral hazard by, banks. The regulator can screen banks prior to giving them a licence, audit them ex post to learn the success probability of their projects, and impose capital adequacy requirements. Capital...

The 2007–2009 financial crisis saw a vast expansion in deposit insurance guarantees around the world and yet our understanding of the design and consequences of deposit insurance schemes is in its infancy. We provide a new rationale for the provision of deposit insurance. In our model the...

This paper examines common regulation as cause of interbank contagion. Studies based on the correlation of bank assets and the extent of interbank lending may underestimate the likelihood of contagion because they do not incorporate the fact that banks have a common regulator. In our model, the...
