在带注资的Cramer-Lundberg模型基础上,考虑交易费用和管理费用的情况,以股东的折现分红减去惩罚折现注资与管理费之和的差的期望值最大化为目标,讨论了模型的最优分红和注资策略问题.由随机控制理论建立相应的HJB方程,得到了相应的解及最优策略是band type.这一结论推广了前人的理论,使风险模型更具现实意义.
在帶註資的Cramer-Lundberg模型基礎上,攷慮交易費用和管理費用的情況,以股東的摺現分紅減去懲罰摺現註資與管理費之和的差的期望值最大化為目標,討論瞭模型的最優分紅和註資策略問題.由隨機控製理論建立相應的HJB方程,得到瞭相應的解及最優策略是band type.這一結論推廣瞭前人的理論,使風險模型更具現實意義.

Considering the Cramer-Lundberg model with dividend payments and capital injections in the presence of both transaction and administration costs,in order to maximize the discounted dividend pay-ments minus the penalized discounted capital injections and the costs,by stochastic control theory and the corresponding Hamilton-Jacobi-Bellman equation,a method to determine numerically the solution to the in-tegro-differential equation was derived and showed that the optimal strategy was band type.This conclusion which put forwords the theory of former researchers was widely used,and made the risk model more realis-tic.
