Abstract:Consider a continuous-time risk model with two correlated classes of insurance business and risky investments whose price processes are geometric Lévy processes. By assuming that the correlation comes from a common shock, and the claim sizes are heavy-tailed and pairwise quasi-asymptotically independent, we investigate the tail behavior of the sum of the stochastic present values of the two correlated classes, and a uniform asymptotic formula is obtained.
Keywords:Consistently varying tails  Dominatedly varying tails  Investment return  Geometric Lévy process  Pairwise asymptotic independence  Uniformity
