We study how relationship lending and transaction lending vary over the business cycle. We develop a model in which relationship banks gather information on their borrowers, which allows them to provide loans for profitable firms during a crisis. Due to the services they provide, operating costs...

This Paper analyses the transmission mechanisms of monetary policy in a general equilibrium model of securities markets and banking with asymmetric information. Banks' optimal asset/liability policy is such that in equilibrium capital adequacy constraints are always binding. Asymmetric...

This paper reexamines the classical issue of the possible trade-o s between banking competition and financial stability by highlighting different types of risk and the role of leverage. By means of a simple model we show that competition can affect portfolio risk, insolvency risk, liquidity...

We model systemic risk in an interbank market. Banks face liquidity needs as consumers are uncertain about where they need to consume. Interbank credit lines allow banks to cope with these liquidity shocks while reducing the cost of maintaining reserves. However, the interbank market exposes the...

This paper addresses the issue of the optimal behaviour of the Lender of Last Resort (LOLR) in its microeconomic role regarding individual financial institutions in distress. It has been argued that the LOLR should not intervene at the microeconomic level and let any defaulting institution face...

We investigate the optimal regulation of financial conglomerates that combine a bank and a non-bank financial institution. The conglomerate’s risk-taking incentives depend upon the level of market discipline it faces, which in turn is determined by the conglomerate’s liability structure. We...

In an environment characterized by weak contractual enforcement, sovereign lenders can enhance the likelihood of repayment by making their claims more difficult to restructure. We show within a simple model how competition for repayment between lenders may result in sovereign debt that is...

This paper analyses the tendency for nations to break up as a result of a trade-off between the aggregate efficiency losses from separation and the redistributive gains to the majority, which can occur in all regions, even when there are no transfers across these regions. We show that...

A growing and deepening divide has opened up between countries where economic development has “taken off” and those caught in a vicious cycle of institutional backwardness and macroeconomic instability. This “Great Divide” is visible in almost every measure of economic performance, such...

We analyze contagious sovereign debt crises in financially integrated economies. Under financial integration banks optimally diversify their holdings of sovereign debt in an effort to minimize the costs with respect to an individual country's sovereign debt default. While diversification...
