      摘要考慮了帶隨機(jī)回報(bào)的一類離散馬氏風(fēng)險(xiǎn)模型.在此模型中,賠付的發(fā)生概率,賠付額的分布函數(shù)都是由一個(gè)離散時(shí)間的馬氏鏈調(diào)控.當(dāng)保險(xiǎn)公司采用門檻分紅策略時(shí),通過計(jì)算得到了破產(chǎn)前的期望折現(xiàn)分紅總量滿足的一組線性方程.最后,給出了期望折現(xiàn)分紅總量的顯式解析式.

      關(guān)鍵詞馬氏風(fēng)險(xiǎn)模型;隨機(jī)回報(bào);門檻分紅;期望折現(xiàn)分紅量

      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
