一类离散相依索赔风险模型的随机分红问题
Randomized Dividends in a Discrete Risk Model with Time-Correlated Claims
【摘要】 该文将随机保费收入、相依索赔以及随机分红策略引入到复合二项风险模型中,并研究该模型下的随机分红问题.运用母函数的方法,推导得到保险公司直至破产前的期望累积折现分红量满足的差分方程及其解.最后,通过几个数值例子展示了所得结果.
【Abstract】 In this paper,the compound binomial risk model is extended by involving the random premium income with time-correlated claims and random dividend strategy.By the method of generating function,the difference equation and its solution for the expected cumulated discounted dividends until ruin are obtained.Finally,the effect of related parameters on the total expected discounted dividends are shown in several numerical examples.
