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...

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...

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...

Before 2007, financial crises were not widely studied in economics and finance. The lack of importance ascribed to financial stability and our limited knowledge of this topic were significant contributors to the crisis. This paper suggests five areas where new theories are needed. These are...

The financial sector is heavily regulated in order to prevent financial crises. The recent crisis showed how ineffective this regulation and other types of government intervention were in achieving this aim. We argue that the crisis was primarily caused by housing price bubbles. These occurred...

As of this writing in June 2016, the markets are predicting Venezuela to be on the brink of default. On June 1, 2016, the 6 month CDS contract traded at about 7000bps which translates into a likelihood of default of over 90%. Our interest in the Venezuelan crisis is that its outstanding...
