Stress testing has become a crucial point on the Basel II agenda, mainly as Pillar I estimatesdo not explicitly take portfolio concentration into account. We start from the credit portfolioof the German pension insurer being a cross-sectional representation of the German economyand subsequently...

In this paper we investigate the interaction between a credit portfolio and another risktype, which can be thought of as market risk. Combining Merton-like factor models forcredit risk with linear factor models for market risk, we analytically calculate their interriskcorrelation and show how...

Inferiorinformation quality also reduces the quality of borrowers and may lead to financial instability ofbanks and corporates if risk taking is excessive. Recent theories conjecture that banks can mitigatethe...

This paper first provides a simple but very general framework for credit portfolio modellingwhich is based on the distinction between systematic and unsystematic risk. Unsystematicor borrower-specific risk vanishes through diversification in a very large, infinitelyfine-grained portfolio. The...

Evidence from many countries in recent years suggests that collateral values and recovery rates on corporate defaults can be volatile and, moreover, that they tend to go down just when the number of defaults goes up in economic downturns.(...)
