考虑了在一定条件下允许负资产运行的古典风险模型.通过不破产概率满足的积分一微分方程,得到此模型不破产概率的明确表达式,并且与古典风险模型不破产概率进行了比较.
The risk model in negative surplus is considered. Using the integro-differential equation that the survival probability satisfies, the explicit expression for the survival probability is obtained, and compare it with that of classical model.
