The Taylor rule sets the optimshort-term rate asNeutrrate + 0.5 × (G growth forecast – G growth tren + 0.5 × (Inflation forecast – Inflation target)Applying numbers from Exhibit 3,2.0% = 2.5% + 0.5 × (2.0% - 1.0%) + 0.5 × (1.5% - 3.5%).A is incorrect. The fferenbetween the earnings trenanforecast is incluwith eafferenbetween forecast antrenbeing weighte0.333.2.8% = 2.5% + 0.333 × (2.0% – 1.0%) + 0.333 × (1.5% -– 3.5%) + 0.333 × (4.0% – 2.0%)B is incorrect. The inflation anG austments are not multiplie0.5.本题考查的是泰勒公式C是正确的。泰勒规则将最优短期利率设为中性利率+ 0.5 × (G增长预测- G增长趋势)+ 0.5 ×(通胀预测-通胀目标)2.0% = 2.5% + 0.5××(2.0% - 1.0%)+ 0.5(1.5% - 3.5%)。A是不正确的。收益趋势和预测之间的差异被包括在内，预测和趋势之间的每个差异被错误地使用了0.333加权。B是不正确的。通胀和G的调整没有乘以0.5。 Baseon Taylor’s rule, with assumption of equweights applieto forecast versus trenmeasures, the short-term rate is expecteto increase from the current 1.23%, anthe yielcurve is expecteto flatten for longer maturities.我还以为这里的1.23%是中性利率。为什么这个不是。
