基于利率贴现模型的随机占优比较

Stochastic dominance comparisons based on interest discount model

建立单笔投资的利率贴现模型按照一阶随机占优序、二阶随机占优序以及风险偏好型随机占优序递减的充分条件。若组合系数按超优序递减,投资组合情况下的利率贴现模型按照二阶随机占优序、风险偏好型随机占优序递减的充分条件也做了分析。

The sufficient conditions for interest discount models increasing in the sense of the first-order stochastic dominance,the second-order stochastic dominance,and the risk-loving stochastic dominance were first given in this paper.We also obtained the sufficient conditions for weighted interest discount models increasing in the sense of the second-order stochastic dominance,and the risk-loving stochastic dominance when the weights decrease in the sense of the majorization order.
