摘要
在经典复合泊松模型的基础上,研究线性红利边界下两步保费率风险模型的Gerber-Shiu贴现罚金函数.根本目的是推导出它的微积分方程和偏微积分方程.同时给出了线性红利边界下Lundberg基本方程;利用Laplace变换求出了最终破产概率.
The classical compound Poisson risk model with a two-step premium rate is considered in this paper, which is under the linear dividend barrier. Gerber-Shiudiscounted penalty function is studied. The main purpose is to deduce the integro-differential equations and the partial integro-differential equations for the discounted penalty function. Lundberg fundamental equation is given also.
