Marshall–Olkin type copulas generated by a global shock
Abstract : A way to transform a given copula by means of a univariate function is presented. The resulting copula can be interpreted as the result of a global shock affecting all the components of a system modeled by the original copula. The properties of this copula transformation from the perspective of semi–group action are presented, together with some investigations on the impact on the tail behavior. Finally, the whole methodology is applied to model risk assessment.
