不同利息力模型下生存年金的比较

Comparison of various life annuities with different models of interest force

给出了利息力分别为常数和、变量、随机变量时的生存年金精算现值模型及其等价模型,通过实例证明了采用不同利息力模型时,尽管整个支付期间利息力的均值相同,但生存年金精算现值仍具有一定的差异.

This paper gives the models and their equivalent models of life annuity with constant interest for-ce,variant interest force and random interest force.And it gives examples to verify the actuarial present values of life annuity is different with various models of interest force,though the average of interest force is equal during the payoff period.
