摘 要: 在本文中,我们研究了一个离散时间风险模型的破产概率.在此风险模型中,保险公司的剩余资本被用于进行风险投资.我们运用纯概率的手法建立了无限时间破产概率的渐近显式, 从而将Tang和Tsitsiashvili(2003)近期的一个结果推广到了无限时间的场合. In this paper, we investigate the ruin probabilitY of a discrete-time risk model, in which the surplus of an insurance business is currently invested into a risky asset. Using a purely probabilistic treatment, we establish explicit asymptotic relations for the infinite-time ruin probabilities, hence we extend a recent result of Tang and Tsitsiashvili (2003) to the infinite-time case.
