摘要

In contrast with the classical Cramer-Lundberg model where the premium process is a linear function of time, we consider the ruin probability under the risk model where the aggregate premium consists of both a compound Poisson process and a linear process of time. Moreover, a constant interest force is also taken into account in our model. We restrict ourselves to the case where the claim size is heavy-tailed, i.e., the equilibrium distribution function of the claim size belongs to a wide subclass of the subexponential distribution. An asymptotic formula for the ruin probability is obtained by using the similar method of Kalashnikov and Konstantinides (2000). The asymptotic formula we get here is the same as the one in Asmussen (1998), Kliippelberg and Stadtmiiller (1998), and Kalashnikov and Konstantinides (2000) which did not consider the stochastic premium.
