This paper reexamines from a theoretical perspective the role of monetary and macroprudential policies in addressing the build-up of risks in the financial system. We construct a stylized general equilibrium model in which the key friction comes from a moral hazard problem in firms' financing...

This Paper presents a dynamic model of imperfect competition in banking where banks can invest in a prudent or a gambling asset. We show that if intermediation margins are small, the banks’ franchise values will be small, and in the absence of regulation only a gambling equilibrium will exist....

We analyze the cyclical effects of moving from risk-insensitive (Basel I) to risk-sensitive (Basel II) capital requirements in the context of a dynamic equilibrium model of relationship lending in which banks are unable to access the equity markets every period. Banks anticipate that shocks to...

This paper studies the strategic interaction between a bank whose deposits are randomly withdrawn, and a lender of last resort (LLR) that bases its decision on supervisory information on the quality of the bank’s assets. The bank is subject to a capital requirement and chooses the liquidity...

We analyse the implications for the pricing of bank loans of the reform of capital regulation known as Basel II. We consider a perfectly competitive market for business loans where, as in the model underlying the internal ratings based (IRB) approach of Basel II, a single risk factor explains...

This Paper analyses the determinants of regulatory capital (the minimum required by regulation) and economic capital (the capital that shareholders would choose in absence of regulation) in the context of the single risk factor model that underlies the New Basel Capital Accord (Basel II). The...
