This paper examines the role of macroprudential capital requirements in preventing inefficient credit booms in a model with reputational externalities. In our model, unprofitable banks have strong incentives to invest in risky assets when macroeconomic fundamentals are good in order to avoid the...

This paper compares alternative procedures to mitigate the procyclicality of the new risk-sensitive bank capital regulation (Basel II). We estimate a model of the probabilities of default (PDs) of Spanish firms during the period 1987-2008, and use the estimated PDs to compute the corresponding...

The Basel Committee on Banking and Supervision established minimum capital requirements for banks in their 1988 Capital Accord. This capital regulation was adopted for European Union banks at the beginning of 1993. After the implementation, a widespread concern emerged about the possible...

This paper examines the macroprudential roles of bank capital regulation and monetary policy in a Dynamic Stochastic General Equilibrium model with endogenous financial frictions and a borrowing cost channel. We identify various transmission channels through which credit risk, commercial bank...

Prompt Corrective Action (PCA) prescribes prompt and deterministic termination of banks with insufficient levels of book-value capital. This paper investigates whether reliance on book-value capital is a good policy choice and if PCA is an optimal regulatory approach. I use a variant of DeMarzo...

The New Basel Accord for bank capital regulation is designed to better align regulatory capital to the underlying risks by encouraging better and more systematic risk management practices, especially in the area of credit risk. We provide an overview of the objectives, analytical foundations and...

We consider a model of optimal bank closure rules (cum capital replenishment by banks), with Poisson-distributed audits of the bank's asset value by the regulator, with the goal of eliminating (ameliorating) the incentives of levered bank shareholders/managers to take excessive risks in their...

Auditing is introduced into a model of bank capital regulation. Deterministic and stochastic auditing strategies are studied. Contrary to intuition, auditing of bank risk should be focused on the safest banks because they hold the least amount of capital. Risky banks, which hold more capital,...
