英文摘要:
Complementing existing results on minimal ruin probabilities, we minimize expected discounted penalty functions (or Gerber-Shiu functions) in a Cramer-Lundberg model by choosing optimal reinsurance. Reinsurance strategies are modelled as time dependant control functions, which leads to a setting from the theory of optimal stochastic control and ultimately to the problem\'s Hamilton-Jacobi-Bellman equation. We show existence and uniqueness of the solution found by this method and provide numerical examples involving light and heavy tailed claims and also give a remark on the asymptotics.

中文摘要:
为了补充现有关于最小破产概率的结果,我们在Cramer-Lundberg模型中通过选择最优再保险来最小化预期贴现惩罚函数(或Gerber-Shiu函数)。再保险策略被建模为与时间相关的控制函数,这导致了从最优随机控制理论到问题的Hamilton-Jacobi-Bellman方程的设定。我们证明了用这种方法得到的解的存在性和唯一性,并给出了涉及轻尾和重尾索赔的数值例子,还对渐近性进行了说明。
