An estimate of the ERP consistent with the Grinold-Kroner model is closest to
选项:
A.
2.7%
B.
3.0%
C.
4.3%
解释:
B is correct.
i = 4% per year (long-term forecast of inflation)
g = 4% per year (growth in real GDP)
Δ (P/E0 = 1% per year (growth in market P/E)
dy = 1% per year (dividend yield or the income portion)
Risk-free return = rf = 7% per year (for 10-year maturities)
Using the Grinold-Kroner model, the ERP estimate is
ERP = {1.0 + 1.0 +[4.0 + 4.0 + 0.0)] } – 7.0 = 3.0%.
The premium of 3.0% compensates investors for average market risk, given expectations for inflation, real earnings growth, P/E growth, and anticipated income.
为什么不用上面算的平均的国债收益率代替rf
