Nowcasting and the Taylor Rule
提出一个“即时预测”泰勒规则,保留原规则形式但采用政策制定者可观测的现实信息,发现美国实际联邦基金利率与该规则建议一致。
Actual federal funds rates in the U.S. have, at times, deviated from the recommendations of a simple Taylor rule. This paper proposes a “nowcasting” Taylor rule that preserves the form of the Taylor rule but encompasses realistic assumptions on information observable to policymakers. Because contemporaneous inflation rates and output gaps are not observable at the time policy is set, policymakers must form “nowcasts.” The optimal nowcast will depend, in part, on forecast uncertainty whenever policymakers have asymmetric costs to over‐ and underpredicting inflation and output. Empirical evidence shows that actual policy rates are consistent with those recommended by a nowcasting Taylor rule.
