Involving copula functions in Conditional Tail Expectation
AbstractA new notion to risk measures preserving the coherence axioms, that we call Copula Conditional Tail Expectation (CCTE), is given. This risk measure describes the expected amount of risk that can be experienced given that a potential bivariate risk exceeds a bivariate threshold value, and provides an important measure for right-tail risk. Our goal is to propose an alternative risk measure which takes into account the fluctuations of losses and possible correlations between random variables. Finally, our risk measure is applied to the real financial data.
