教材P380,13,14题:请教各位---- Asset Class Geometric Return(%) Equities 8.0 Corporate Bnds 6.5 Treasury Bills 2.5 Inflation 2.1
13. The risk premium for equties is cloest to : A. 5.4%; B. 5.5%; C. 5.6%
14. The risk premium for corportae bonds is cloest to :
A. 3.5%; B. 3.9%; C. 5.0%
答案分别是A和B。后面的解析是:(1+8%)/(1+2.5%); (1+6.5%)/(1+2.1%) 【我的理解是:】 根据公式: 1+r=(1+r[rF])X(1+π)X(1+RP) 那么题目中的计算不应该是:(1+8%)/[(1+2.5%)(1+2.1%)]=3.2%和 (1+6.5%)/[(1+2.5%)(1+2.1%)]=1.8%吗? |
