Abstract
The natural rate of interest (NRI) plays a critical role in maintaining stable and effective monetary policy. However, its unobservable nature has led most research to focus on quantitative methods for identifying its shifts, leaving theoretical approaches relatively underexplored. This study addresses this gap by examining how a central bank can implement optimal monetary policy within the New Keynesian framework by tracking NRI fluctuations after real shocks. The analysis demonstrates that when economic agents have strong confidence in policy consistency, the central bank can accurately detect NRI shifts within two periods, regardless of the type of real shocks. This finding implies that adopting an NRI-based interest rate rule may contribute to enhancing policy effectiveness.
期刊介绍：
Economic Modelling fills a major gap in the economics literature, providing a single source of both theoretical and applied papers on economic modelling. The journal prime objective is to provide an international review of the state-of-the-art in economic modelling. Economic Modelling publishes the complete versions of many large-scale models of industrially advanced economies which have been developed for policy analysis. Examples are the Bank of England Model and the US Federal Reserve Board Model which had hitherto been unpublished. As individual models are revised and updated, the journal publishes subsequent papers dealing with these revisions, so keeping its readers as up to date as possible.
