英文摘要:
The Gerber-Shiu function provides a way of measuring the risk of an insurance company. It is given by the expected value of a function that depends on the ruin time, the deficit at ruin, and the surplus prior to ruin. Its computation requires the evaluation of the overshoot/undershoot distributions of the surplus process at ruin. In this paper, we use the recent developments of the fluctuation theory and approximate it in a closed form by fitting the underlying process by phase-type Levy processes. A sequence of numerical results are given.

中文摘要:
Gerber Shiu函数提供了一种衡量保险公司风险的方法。它由一个函数的期望值给出,该函数依赖于破产时间、破产时的赤字和破产前的盈余。其计算要求评估破产时盈余过程的超调/欠调分布。在本文中,我们利用波动理论的最新发展,通过用相位型Levy过程拟合基本过程,以闭合形式对其进行近似。给出了一系列数值结果。
