摘要
研究了一类经典Cramér-Lundberg风险模型,其在安全负载体系下进行赋税,且按门槛策略进行分红.针对此模型,推导了破产前的期望折现总分红的表达式,并给出单独赔付额服从指数分布下的精确解.最后给出破产时刻之前的期望折现总分红以及最优门槛的数值模拟结果.
A classical Cramér-Lundberg risk model with a threshold dividend strategy and loss-carry forward tax payments was studied. For this model, the closed-form expressions for the expected accumulated discounted dividends until ultimate ruin was derived and the explicit solution was presented when the individual claim amount follows an exponential distribution. Finally, numerical illustrations of the expected accumulated discounted dividends until ruin and the optimal threshold were given.
