问题如下：
Suppose the neutral real policy rate is 2.25%, the target inflation rate is 2%, and trend growth is estimated to be 2.5%. If growth is expected to be 3.5% and inflation is expected to be 3%, calculate the nominal policy rate according the Taylor rule.
选项：
A.4%
B.6.25%
3.25%
解释：
B is correct.
解释：
依据泰勒公式，可得：
2.25% + 3% + 0.5 (3.5% – 2.5%) + 0.5 (3.0% – 2.0%) = 6.25%
经典题里有两道都是没有在neutral rate的基础上加expected inflation, 请问老师考试时该如何处理，谢谢。

NO.PZ2020012201000013 Taylor公式是什么？
NO.PZ2020012201000013 6.25% 3.25% B is correct. 依据泰勒公式，可得 2.25% + 3% + 0.5 (3.5% – 2.5%) + 0.5 (3.0% – 2.0%) = 6.25% 原版书是Y forecast- Y tren该对应estimateexpecte，为什么题目中反了？
