One of the main issues of risk management is the aggregation
of individual risks. A powerful concept to
aggregate the risks — the copula function — has been
introduced in finance by Embrechts, McNeil, and
Straumann [1999,2000]. In their papers, the authors
clarify the essential concepts of dependence and correlation
and certainly will greatly influence the risk
management industry. The goal of this paper is to provide
simple applications for the practical use of copulas
for risk management from an industrial point of view.
First, we remind some basics about copulas. Then,
some applications of copulas for market risk, credit risk
and operational risk are given. We will not provide a
full mathematical treatment of the subject and we refer
interested readers to Joe  or Nelsen .
