Abstract

In this paper, the fully discrete risk model is considered. Claim sizes are assumed to be integer-valued. A new method is employed to derive some explicit formulas of the Gerber-Shiu penalty function. Characteristic equations corresponding to recursive equations satisfied by Gerber-Shiu penalty function are analyzed and explicit expressions of the penalty function are then obtained. As a special case, the probability of ruin is obtained.
