研究了带随机利率的双二项风险模型的破产问题,得到了终极破产概率的上界、描述破产严重程度的破产前盈余分布和破产赤字的联合分布的递推公式,进而得到了终极破产概率、破产前盈余和破产瞬时盈余满足的积分方程.
Bankruptcy under double binomial risk model with random interestrate is discussed. Upper bound for the ultimate ruin probability and the recursive formula for the joint distribution of surplus immediately before ruin and deficit at ruin are derived. Furthermore, the integration equation for ultimate ruin probability and surplus immediately before ruin and deficit at rain are developed.
