研究了马氏环境下双Cox风险模型的折现罚金函数
利用后向差分法得到了折现罚金函数所满足的积分方程
进而得到了破产概率、破产前瞬时盈余、破产时赤字的各阶矩所满足的积分方程.
In this paper
we research the expected discounted penalty function with double Cox risk model in a Markovian environment.By a backward differential argument
the integral equation satisfied by the expected discounted penalty function is driven.Then we get the equations satisfied by ruin probability
the moments of the surplus immediately prior to ruin and deficit at ruin.
