Abstract

In this paper, we propose the dependence notions of weakly stochastic arrangement increasing through left tail probability (LWSAI) and weakly stochastic arrangement increasing (WSAI) to model multivariate dependent risks. We derive properties and characterizations of these new notions and show that many existing dependence structures are the special cases of these notions of dependence. We apply the dependence notions of LWSAI and WSAI to the problem of optimal portfolio selections with dependent risks and generalize many existing studies.
