摘要: 在考虑Markov-modulated风险模型分红约束和交易费用的基础上,以股东的折现分红减去折现注资之差的期望值最大为目标,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HJB方程,得到相应的最优策略为Threshold策略.

Abstract: Considering control of dividends and capital injections of the Markov-modulated risk model with restricted densities and transaction costs,with maximizing the discounted dividend payments minus the penalized discounted capital injections as the goal,the optimal dividends and capital injections strategy was discussed.By stochastic control theory and the Hamilton-Jacobi-Bellman equation,it was derived that the corresponding best strategy was Threshold strategy. -
