带双阈值的一类更新风险模型的Gerber-Shiu折现罚函数
A General Class of Semiparametric Rates Models for Recurrent Event Data
【摘要】 本文考虑一类索赔时间间隔为Erlang(2)分布的"双界限"分红模型,在这种模型中,当盈余超过上限时分红以不超过保费率的速率付出,低于下限后保费率增大,得到了关于Gerber-Shiu罚金折现期望函数满足的积分-微分方程以及更新方程,进一步讨论了更新方程的解.
【Abstract】 This paper studies a renewal risk model in which the Inter-claim times are Erlang(2)distributed.Under such a strategy,when the surplus is above the upper barrier, dividends are paid at a constant rate that does not exceed the premium rate,and the premium rate increases if the surplus falls below the lower barrier.The integro-differential equations and the renewal equation for the Gerber-Shiu discounted penalty function are obtained.Furthermore,we discuss the solution to the renewal equation.
