We develop a model where banks invest in reserves and loans, and face aggregate liquidity shocks. Banks with liquidity shortage sell loans on the interbank market. Two equilibria emerge. In the no default equilibrium, all banks hold enough reserves and remain solvent. In the mixed equilibrium,...

We develop a model where banks invest in reserves and loans, and trade loans on the interbank market to deal with liquidity shocks. Two types of equilibria emerge, depending on the degree of credit market competition and the level of aggregate liquidity risk. In one equilibrium, all banks keep...

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...

We develop a model in which asset commonality and short-term debt of banks interact to generate excessive systemic risk. Banks swap assets to diversify their individual risk. Two asset structures arise. In a clustered structure, groups of banks hold common asset portfolios and default together....

We develop a model where institutions form connections through swaps of projects in order to diversify their individual risk. These connections lead to two different network structures. In a clustered network groups of financial institutions hold identical portfolios and default together. In an...

This paper analyzes the role of liquidity regulation and its interaction with capital requirements. We first introduce costly capital in a bank run model with endogenous bank portfolio choice and run probability, and show that capital regulation is the only way to restore the efficient...

We provide new evidence on how deposit funding affects bank lending. For identification, we exploit a tax reform in Italy that induced households to substitute bank bonds with deposits. We find that banks with larger increases in deposits expand the supply of credit lines and long-term credit to...

Most analyses of banking crises assume that banks use real contracts but in practice contracts are nominal. We consider a standard banking model with aggregate return risk, aggregate liquidity risk and idiosyncratic liquidity shocks. With non-contingent nominal deposit contracts, a decentralized...
