| Abstract: | In this paper, a discret-time risk model with two independent classes of insurance business is proposed, when the arrival processes of the claims are all described by binomial processes. The integral equation with its expected penalty function and its ruin probability are derived. Recursive formulas are provided for the computation of the bankruptcy probability in finite time, the time distribution of bankruptcy, and the joint distribution of the surplus immediately before bankruptcy and the deficit during bankruptcy. |
