摘要
研究保险公司在摩擦市场中带终端残值的最优风险投资-超额损失再保-阈值分红问题,通过使用动态规划原理得到HJB方程,利用微积分理论分析并求解了最优投资-超额损失再保险策略和最优红利函数.最后在红利贴现率等于0的情形下,求解了最优策略与红利函数的显式解.
Abstract
The optimal investment-excess loss reinsurance-threshold dividend question with terminal salvage value of insurance company in friction market is studied.The HJB equation is obtained by using dynamic programming principle,and the optimal investment-excess loss reinsurance strategies and optimal dividend function are analyzed and solved by using differential calculus theory.Finally,the closed solution of the optimal strategy and dividend function is completely solved in the special case where the dividend discount rate is equal to 0.
