问题如下：
Country Y’S long-term inflation forecast at a rate of 4.5 percent per year. The forward dividend yield on the index is 1.5 percent. Currently, the 10-year government bond yield is 6 percent. Earnings in the public corporate sector are expected to grow at a 6.5percent per year. Consistent with that, the market P/E ratio is expected to grow at 2 percent per year. Based on the given information, the equity risk premium is calculated by using supply side estimate is closest to:
选项：
A.5.4 percent.
B.6.0 percent.
C.9.0 percent.
解释：
C is correct.
考点：Equity risk premium
解析：C是正确的。根据supply side模型，股权风险溢价等于= {[(1 + EINFL)(1 + EGREPS)(1 + EGPE) − 1.0] + EINC}−Expected risk-free return
EINFL = 4.5% per year
EGREPS = 6.5 percent per year
EGPE = 2 percent per year
EINC = 1.5 percent per year
RF= 6 percent per year
带入公式, 我们可以得到:{[(1.045)(1.065)(1.02) − 1.0] + 0.015} − 0.06 = 0.09 = 9 percent.
请问这一类型系列的公示怎么记住？好像有点乱脑子里
