1、这个宏观模型又叫supply side estimate,它是由Ibbotson-Chen这两个人搞出来的，所以都是一回事儿：
2、在成熟的发达国家市场，整个国家的real GDP增长就等于全体公司real earning的增长，这两个指标是可以互换使用的。请见原版书的详细解释：
Expected growth in real earnings per share. This quantity should approximately track the real GDP
growth rate. An adjustment upward or downward to the real GDP growth rate can be made for any
expected differential growth between the companies represented in the equity index being used to
represent the stock market and the overall economy

C is correct.Accorng to this mol, the equity risk premium is Here: Equity risk premium = {[(1 + EINFL)(1 + EGREPS)(1 + EGPE) − 1.0] + EINC}−Expecterisk-free returnEINFL = 4 percent per ye(long-term forecast of inflation)EGREPS = 5 percent per ye(growth in reearnings)EGPE = 1 percent per ye(growth in market P/E ratio)EINC = 1 percent per ye(vinyielor the income portion)Risk-free return = 7 percent per ye(for 10-yematurities)substitution, we get:{[(1.04)(1.05)(1.01) − 1.0] + 0.01} − 0.07 = 0.113 − 0.07 = 0.043 or 4.3 percent. 想问一下老师，这里的Risk-free return = 7 percent per ye为什么要用 10-yematurities？在Supply Si Estimates里，Rf是要用长期的吗？谢谢！

The geometric mereturn relative to 10-yegovernment bonreturns over 10years is 2 percent per year. 2%为什么不能作为rf
NO.PZ201512300100000304 这道题计算为什么用的是EGREPS = 5 percent per ye(growth in reearnings) 而不是用的reG growth rate 4%算？
