This article compares the linkages between credit fundamentals, ratings and value-at-risk measures for CDO tranches with those for corporate bond exposures. A sensitivity analysis incorporating market information and rating migrations data reveals that the behaviour of CDO tranche ratings can...

Equity and credit-default-swap (CDS) markets are in disagreement as to the extent to which asset returns co-move across firms. This suggests market segmentation and casts ambiguity about the asset-return correlations underpinning observed prices of portfolio credit risk. The ambiguity could be...

In order to analyze the pricing of portfolio credit risk – as revealed by tranche spreads of a popular credit default swap (CDS) index – we extract risk-neutral probabilities of default (PDs) and physical asset return correlations from single-name CDS spreads. The time profile and overall...

This paper develops an empirical procedure for analyzing the impact of model misspecification and calibration errors on measures of portfolio credit risk. When applied to large simulated portfolios with realistic characteristics, this procedure reveals that violations of key assumptions of the...

This paper focuses on the asymptotic single-risk-factor (ASRF) model in order to analyze the impact of specification and calibration errors on popular measures of portfolio credit risk. Violations of key assumptions of this model are found to be virtually inconsequential, especially for large,...

A model-based assessment of credit risk is subject to both specification and calibration errors. Focusing on a well known credit risk model, we propose a methodology for quantifying the relative importance of alternative sources of such errors and apply this methodology to a large data set. We...

This paper extends the standard Diamond-Dybvig model for a general equilibrium in which depositors make their withdrawal decisions sequentially and banks strategically choose their contracts. There is a unique Subgame Perfect Nash Equilibrium (SPNE) in the decentralized economy. Bank runs can...

This paper develops a stochastic dynamic model to examine the impact of capital regulation on banks’ financial decisions. In equilibrium, lending decisions, capital buffer, and the probability of bank failure are endogenously determined. Compared to a flat-rate capital rule, a risk-sensitive...

We seek to assess the relationship between commercial property price movements and the behavior and performance of individual banks in a range of industrialized economies, extending the existing micro literature on bank performance. Our results suggest that commercial property prices tend to be...
