Estimates for the ruin probability in the classical risk model with constant interest force in the presence of heavy tails

In this paper we investigate the ruin probability in the classical risk model under a positive constant interest force. We restrict ourselves to the case where the claim size is heavy-tailed, i.e. the equilibrium distribution function (e.d.f.) of the claim size belongs to a wide subclass of the subexponential distributions. Two-sided estimates for the ruin probability are developed by reduction from the classical model without interest force. (C) 2002 Elsevier Science B.V. All rights reserved.
