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%
老师你好，对泰勒公式我一直有一个疑问，为什么后面加的通货膨胀率是预期的减target而不是target减去预期的？
我的理解是：我们应该去计量预期的离我们目标的通货膨胀率的距离，所以是target-expected
