问题如下:
An analyst observes the following historic geometric returns:
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%
看很多助教回的答案是real return的公式 按照(1+Rnominal)=(1+Rfree)(1+Rinflation)(1+Rrisk premium) 结果不应该是1.008/(1.025*1.021)么 为什么inflation rate不在被除数里?
