问题如下:
Using the data in Exhibit 1 and the investment team’s approach to predict the Fed’s next move, the new fed funds rate will most likely be:
选项:
A.2.9%.
B.2.6%.
C.2.1%.
解释:
Solution
C is correct. The Taylor rule is
Roptimal = Rneutral + [0.5 × (GDPgforecast – GDPgtrend)] + [0.5 × (Iforecast – Itarget)]
= 2.5 + [0.5 × (3.0 – 4.5)] + [0.5 × (3.2 – 2.5)]
= 2.5 – 0.75 + 0.35
= 2.10%
C是正确的,依据泰勒公式可得:
Roptimal = Rneutral + [0.5 × (GDPgforecast – GDPgtrend)] + [0.5 × (Iforecast – Itarget)]
= 2.5 + [0.5 × (3.0 – 4.5)] + [0.5 × (3.2 – 2.5)]
= 2.5 – 0.75 + 0.35
= 2.10%
按照目前的公式计算,最终结果应该是2.1%+3.2%=5.3%吗?如果题目中没有给出neutral rate是real 还是nominal,是按照默认为real rate吗?
