In this paper we investigate the interaction between a credit portfolio and another risk type, which can be thought of … as market risk. Combining Merton-like factor models for credit risk with linear factor models for market risk, we … analytically calculate their interrisk correlation and show how inter-risk correlation bounds can be derived. Moreover, we …

This paper uses the method developed by Bollerslev and Todorov (2011b) to estimate risk premia for extreme events for … from options data. In a second step, jump tail distributions are approximated using the extreme value theory. Applying the … method to German data yields very similar results to the ones shown for the US data. The risk premia for rare events …

The credit value-at-risk model underpinning the Basel II Internal Ratings-Based approach assumes that idiosyncratic … risk has been diversified away fully in the portfolio, so that economic capital depends only on systematic risk … contributions. We develop a simple methodology for approximating the effect of undiversified idiosyncratic risk on VaR. The …

Recently, several institutions have increased their forecast horizons, and many institutions rely on their past forecast errors to estimate measures of forecast uncertainty. This work addresses the question how the latter estimation can be accomplished if there are only very few errors available...

Our paper addresses firm size as a driver of systematic credit risk in loans to small and medium enterprises (SMEs …). Key contributions are the use of a unique data set of SME lending by over 400 German banks and relating systematic risk to … systematic risk from historical default rates. Our results suggest that systematic risk tends to increase with firm size …

This paper considers estimation methods and inference for linear dynamic panel data models with unit-specific heterogeneity and a short time dimension. In particular, we focus on the identification of the coefficients of time-invariant variables in a dynamic version of the Hausman and Taylor...

Two shrinkage estimators for the global minimum variance portfolio that dominate the traditional estimator with respect to the out-of-sample variance of the portfolio return are derived. The presented results hold for any number of observations n = d 2 and number of assets d = 4. The...
