Banks are intrinsically fragile because of their role as liquidity providers. This results in under-provision of liquidity. We analyze the e¤ect of government guarantees on the interconnection between banks' liquidity creation and likelihood of runs in a model of global games, where banks.and...

We develop a two-period model where banks invest in reserves and loans, and are subject to aggregate liquidity shocks. When banks face a a shortage of liquidity, they can sell loans on the interbank market. Two types of equilibria emerge. In the no default equilibrium, banks keep enough reserves...

Government guarantees to financial institutions are intended to reduce the likelihood of runs and bank failures, but are also usually associated with distortions in banks’ risk taking decisions. We build a model to analyze these trade-offs based on the global-games literature and its...

We review the theory of deposit insurance, highlighting the underlying assumptions that were not satisfied during the recent financial crisis and that may have led to serious policy mistakes. In theoretical models, deposit insurance is mostly seen as an equilibrium selection device to avoid...

Bank market power, both in the loan and deposit market, has important implications for credit provision and for financial stability. This article discusses these issues through the lens of a simple theoretical framework. On the asset side, banks choose the quality and quantity of loans. On the...

Loan guarantees represent a form of government intervention to support bank lending. However, their use raises concerns as to their effect on bank risk-taking incentives. In a model of financial fragility that incorporates bank capital and a bank incentive problem, we show that loan guarantees...
