该文考虑变保费率的扰动风险模型,其中索赔的分布是重尾的.对这个风险模型,给出了索赔剩余过程的精细大偏差;同时,还得到了它的有限时间破产概率的Cramér-Lundberg型极限结果.
In this paper, the authors consider a perturbed risk model with variable premium rate and heavy-tailed claims. The precise large deviation for the claim surplus process of this risk model is obtained. The Cramer-Lundberg type limiting results for the finite time ruin probability are also given.
