Titel:
Multivariate models for operational risk. 
Abstract:
In Böcker and Klüppelberg (2005) we presented a simple approximation of Op- VaR of a single operational risk cell. The present paper derives approximations of similar quality and simplicity for the multivariate problem. Our approach is based on modelling of the dependence structure of different cells via the new concept of a Lévy copula.
