均值-方差投资组合理论中的Hansen比率

The Hansen ratio in mean--variance portfolio theory

Aleš Černý

摘要:

它示出的平均值和$L^2$ -范数之间的比率导致一个特别吝啬的描述的均值方差有效前沿和双重定价核的限制被称为Hansen-Jagannathan(HJ)界。由于这个比率以前没有出现在经济理论中,因此将其命名为汉森比率似乎是合适的。初始治疗的均值-方差理论通过汉森比扩展在两个方向上,单调的均值-方差偏好和任意希尔伯特空间设置。一个多周期的例子与IID返回也进行了讨论。

英文摘要:

It is shown that the ratio between the mean and the $L^2$-norm leads to a particularly parsimonious description of the mean-variance efficient frontier and the dual pricing kernel restrictions known as the Hansen-Jagannathan (HJ) bounds. Because this ratio has not appeared in economic theory previously, it seems appropriate to name it the Hansen ratio. The initial treatment of the mean-variance theory via the Hansen ratio is extended in two directions, to monotone mean-variance preferences and to arbitrary Hilbert space setting. A multiperiod example with IID returns is also discussed.
