【摘要】 该文研究了随机时间区间保险公司的最优分红和再保险策略.保险人的目标是在随机时间或破产时间到达时使保险公司的价值最大化.这个价值由三部分组成:到随机时间或破产时间的分红,随机时间或破产时间的盈余和公司的品牌价值.该文使用随机控制方法确定保险公司的联合最优策略.结果显示,当且仅当品牌价值或盈余过高时,管理者应考虑不进行再保险,当盈余增加时购买更少的再保险,而分红总是采用障碍策略进行分配.更多还原

【Abstract】 In this paper,we investigates optimal dividend and reinsurance policies for an insurer with a random time horizon.The goal of the insurer is to maximize the value of the insurance company when the random time or the ruin time arrives.This value consists of three parts:the dividends up to the random time or the ruin time,the surplus at the random time or the ruin time and the company ’s brand value.We identify the insurer ’s joint optimal strategies using stochastic control methods.The results reveal that managers should consider no reinsurance if and only if the brand value or the surplus is too high,less reinsurance is bought when the surplus increases,and dividends are always distributed using the barrier strategy.更多还原
