【Abstract】 This paper concentrates on life insurance model with stochastic rate of interest, we discuss the properties of average claim amount in a portfolio of policies. By analyzing the results of the model, we can see, with the increase of the number of insured, the risk of stochastic rate of interest cannot be reduced, considering a special model of stochastic rate of interest, we compare the cost of average claim between stochastic rate of interest and constant rate of interest.更多还原
