Let X denote the loss initially assumed by an insurer. In a reinsurance design, the insurer cedes part of its loss, say f (X), to a reinsurer, and thus the insurer retains a loss I f (X) = X − f (X). In return, the insurer is obligated to compensate the reinsurer for undertaking the risk by paying the reinsurance premium. Hence, the sum of the retained loss(More)

This paper establishes some asymptotic results for both finite and ultimate ruin probabilities in a discrete time risk model with constant interest rates, and individual net losses in R −α , the class of regular variation with index α > 0. The individual net losses are allowed to be generally dependent while they have zero index of upper tail dependence, so(More)
Under certain assumptions on the dependence structure of the residual lives of the in-sureds (independent, positively/negatively associated), in this paper we establish some laws of large numbers for the convex upper bounds, derived by the technique of comonotonicity, of the present value function of a homogenous portfolio composed of the whole-life(More)
