The subprime crisis revealed that the adoption of suitable systems for the management of credit risk is of utmost concern. The Basel Committee on Banking Supervision (2009) advises banks to use credit portfolio models with caution when assessing the capital adequacy. This paper investigates...

Bank regulators interfere with the efficient allocation of resources for the sake of financial stability. Based on this trade-off, I compare how different capital requirements affect default probabilities and the allocation of market shares across heterogeneous banks. In the model, banks‘...

We use a quasi-experimental research design to examine the effect of model-based capital regulation on the pro-cyclicality of bank lending and firms' access to funds. In response to an exogenous shock to credit risk in the German economy, capital charges for loans under model-based regulation...

This paper theoretically analyzes the addition of a leverage ratio to a risk-weighted capital ratio, and its impact on the banks' risk-taking and the credit supply. We show that such capital requirements à la Basel III reduce the credit supply without necessarily improving banking stability. We...

This paper studies the link between bank capital regulation, bank loan contracts and the allocation of corporate resources across firms' different business lines. Credit risk is lower when firms write contracts that oblige them to invest mainly into projects with highly tangible assets. We argue...

A parsimonious extension of a well-known portfolio credit-risk model allows us to study a salient stylized fact - abrupt switches between high- and low-loss phases - from a risk-management perspective. As uncertainty about phase switches increases, expected losses decouple from unexpected...

I develop a theoretical model to examine the effect of capital requirements on risk taking and market structure of banks. Within a portfolio choice model, I allow for heterogeneous productivity among banks and consider the simultaneous capital regulation with a leverage ratio and a risk-weighted...

The present paper shows that, everything else equal, some transactions to transfer portfolio credit risk to third-party investors increase the insolvency risk of banks. This is particularly likely if a bank sells the senior tranche and retains a sufficiently large firstloss position. The results...
