The risk premium for equities is closest to:
选项:
A.
5.4%.
B.
5.5%.
C.
5.6%.
解释:
A is correct. (1 + 0.080)/(1 + 0.0250) – 1 = 5.4%
前人提问解答:
这道题结合corporate finance知识点,具体公式是(1+nominal rate)=(1+nominal risk-free rate)*(1+risk premium)=(1+real risk-free rate)*(1+inflation)*(1+risk premium)。从这道题而言,直接用nominal rate除以(1+nominal risk-free rate)就可以算出risk premium(Treasury bills的利率就是nominal risk-free rate)
但是在corporate finance 和其他课程里面,我只学过名义利率等于实际利率和通胀率的几何平均公式,并没有讲过名义利率和无风险利率之间的几何平均公式…
