基于风险的现值法

The Present Value Method with Risk

收益现值法中每期的收益都是确定的量。实际上,由于受多种因素的影响,每期的收益仅仅是当期收益的平均值。基于每期收益为正态随机变量,给出了收益现值的计算公式,由此能更好地描述经济活动的变化情况。文中给出了数字例。

It is generally believed that each value of the present value method is determinate. In fact,each value is only the mean of that time. This paper gives some new formulas calculating the present value on the basis of the each value with normal distribution,and also gives an example.
