复合二项风险模型下破产概率的Pollazek-Khinchin公式
Pollazek-Khinchin Formula for Ruin Probability in Compound Binominal Risk Model
【摘要】 本文考虑复合二项风险模型破产概率问题,首先通过研究Gerber-Shiu折现惩罚函数,运用概率论的分析方法得到了其所满足的瑕疵更新方程,再结合离散更新方程理论研究了其渐近性质,最后,运用概率母函数的方法得到了与经典的Gramer-Lundberg模型类似的破产概率Pollazek-Khinchin公式.
【Abstract】 In the paper we studied uses the the Gerber-Shiu discount penalty function in compound binominal model. The first main result is the defective renewal equation which the Gerber-Shiu discount penalty function is satisfied and the asymptotic relationship of the Gerber-Shiu discount penalty function based on the renewal theory. The second main result is Pollazek-Khinchin formula of ruin probability,which is similar to the classic Poisson risk model through using the probability moment generation function.
