| Abstract: | With the decline in mortality and improvement of life expectancy,longevity risk of life insurance companies can not be ignored.Firstly,the natural hedging strategy based on VaR for the longevity risk is investigated.Then a cohort-based extension to the Lee-Carter model is fitted and projected for mortality data of the male population in China.On the basis of the mortality experience,the optimal product mix to hedge longevity risk for the insurers is given.Finally the impacts of the interest rates,age,and pa... |
