首先对文献Eli中在PA-α模型下有关保险费及收益的上下界的结论做了改进,其次给出了一种实际保费的加权计算公式,并给出实际例子说明了所得结果;最后本文讨论了PA-α模型中α未知的情况下,生存给付S=0,保险费Ⅱ给定,保险公司及投保人对死亡给付D的希望取值,并给出D的上下界的计算公式.
This paper makes some improvement of the premium and the benefits under the PA-α model, and gives results in [1] about the upper and lower bounds for the a weighted formula to calculate the premium. An example illustrates the result. At the end of this paper, the authors discuss the death benefits D expected by the insurer and policy holder respectively under the PA-α model with α is unknown and the assumptions that the survival benefit S= 0 and the premium it/is given, and then give the formulae to calculate the upper and lower bounds of D.
