On the distribution of surplus immediately before ruin under interest force

In this paper, we consider a compound Poisson model with a constant interest force for an insurance portfolio. We investigate the distribution of surplus process immediately before ruin in particular. Equations satisfied by the distributions of surplus immediately before ruin and their Laplace transform have been obtained. Some special cases are also discussed and Lundberg-type bounds are presented. © 2001 Elsevier Science B.V.link_to_subscribed_fulltex
