What Does the Yield Curve Tell Us about the Federal Reserve’s Implicit Inflation Target?
用DSGE模型研究收益率曲线如何揭示美联储的隐性通胀目标，发现加入收益率曲线信息后模型预测的通胀预期与调查数据高度吻合，且代理人能快速学习通胀目标，实际与感知目标差距很小。
This paper uses a dynamic stochastic general equilibrium (DSGE) model to explore additional information that can be extracted from the yield curve about the Federal Reserve’s implicit inflation target. In the model, monetary policy follows a nominal interest rate rule with a drifting inflation target, and agents have imperfect information about the persistent component of the inflation target. When the yield curve information is included, the DSGE model generates inflation expectations that are highly correlated with survey data evidence. In the DSGE model, agents quickly learn the inflation target and the gap between the perceived target and the actual target is quantitatively small. This is in contrast to some existing studies that suggest a persistent role of imperfect information even as long‐run inflation expectations have declined and stabilized at a low level since the mid 1980s.
