Tail Mutual Exclusivity and Tail-VaR Lower Bounds [PDF]

SSRN Electronic Journal, 2015
In this paper, we extend the concept of mutual exclusivity proposed by Dhaene and Denuit (1999) to its tail counterpart and baptise this new dependency structure as tail mutual exclusivity. Probability levels are first specified for each component of the random vector.
