摘要考虑了带随机回报的一类离散马氏风险模型.在此模型中,赔付的发生概率,赔付额的分布函数都是由一个离散时间的马氏链调控.当保险公司采用门槛分红策略时,通过计算得到了破产前的期望折现分红总量满足的一组线性方程.最后,给出了期望折现分红总量的显式解析式.

关键词马氏风险模型;随机回报;门槛分红;期望折现分红量

We introduce a constant dividend barrier into the model (1). Assume that any surplus of the insurer above the level b (a positive integer) is immediately paid out to the shareholders so that the surplus is brought back to the level b. When the surplus is below, nothing is done. Once the surplus is negative, the insurer is ruined and the process stops. Let V(n) denote the surplus at time n. Then
