An accurate assessment of tail inequalities and tail asymmetries of financial returns is key for risk management and portfolio allocation. We propose a new test procedure for detecting the full extent of such structural differences in the dependence of bivariate extreme returns. We decompose the...

We present a non-parametric tail dependence estimator which arises naturally from a specific regression model. Above that, this tail dependence estimator also results from a specific copula mixture. -- Upper tail dependence ; nonparametric estimation ; copula

We apply Bayesian Model Averaging and a frequentistic model space analysis to assess the pricing-determinants of credit default swaps (CDS). Our study focuses on the complete model space of plausible models covering most of the variables and specifications used elsewhere in the literature,...

Operationelle Risiken betreffen nahezu jede Geschäftstätigkeit von Banken. Sie verfügen über ein hohes Schadenspotential und stellen eine große Herausforderung für das Risikomanagement der Banken dar. Verena Bayer untersucht Ansätze zur Quantifizierung operationeller Risiken und der...
