问题如下：
An analyst is estimating a forward-looking ERP for a market based on the following information:
Using the Grinold-Kroner model, the estimates of the ERP is closet to:
选项：
A.2.16%
B.4.24%
5.18%
解释：
B is correct.
The ERP using the forward-looking approach is calculated as
ERP = {1.8 – 1.2 + (1.9 + 2.7 + 0.0)} – 0.96
ERP = 5.20 – 0.96 = 4.24%.
请问这里的long term geometric average return of short term government bond 难道不是长期的rf吗？

嗨，爱思考的PZer你好：
1
表格中的数据，并没有提供长期债的数据哈，已知的两个政府债券的收益，都是短期的
同学所说的是最后一行的数据，也是短期债 short-term
2
所谓的 long-term 并不是用来形容债券的期限，而是想说计算的历史数据是长期的
关键词其实是 of 后面的 short term government bond 短期政府债券
3
用跑步举例
如果我们统计过去 5 年博尔特的百米平均成绩，虽然统计的时间很长，有 5 年，但是指标本身是百米成绩，属于【短】跑
如果要对应长期债，类似的举例是统计过去 5 年基普乔格的马拉松平均完赛成绩，指标本身是马拉松成绩，属于【长】跑
----------------------------------------------加油吧，让我们一起遇见更好的自己！

Expecteincome component，对应 。这个东西为什么老师上课讲的时候是对应的分红部分呢（见下图）
