The Post-Pandemic r*
The debate about the natural rate of interest, or r*, sometimes overlooks the point that there is an entire term structure of r* measures, with short-run estimates capturing current economic conditions and long-run estimates capturing more secular factors. The whole term structure of r* matters for policy: shorter run measures are relevant for gauging how restrictive or expansionary current policy is, while longer run measures are relevant when assessing terminal rates. This two-post series covers the evolution of both in the aftermath of the pandemic, with today’s post focusing especially ...

The New York Fed DSGE Model: A Post-Covid Assessment
We document the real-time forecasting performance for output and inflation of the New York Fed dynamic stochastic general equilibrium (DSGE) model since 2011. We find the DSGE's accuracy to be comparable to that of private forecasters before Covid, but somewhat worse thereafter.

Estimating HANK for Central Banks
We provide a toolkit for efficient online estimation of heterogeneous agent (HA) New Keynesian (NK) models based on Sequential Monte Carlo methods. We use this toolkit to compare the out-of-sample forecasting accuracy of a prominent HANK model, Bayer et al. (2022), to that of the representative agent (RA) NK model of Smets and Wouters (2007, SW). We find that HANK’s accuracy for real activity variables is notably inferior to that of SW. The results for consumption in particular are disappointing since the main difference between RANK and HANK is the replacement of the RA Euler equation with ...

Drivers of Inflation: The New York Fed DSGE Model’s Perspective
After a sharp decline in the first few months of the COVID-19 pandemic, inflation rebounded in the second half of 2020 and surged through 2021. This post analyzes the drivers of these developments through the lens of the New York Fed DSGE model. Its main finding is that the recent rise in inflation is mostly accounted for by a large cost-push shock that occurred in the second quarter of 2021 and whose inflationary effects persist today. Based on the model’s reading of historical data, this shock is expected to fade gradually over the course of 2022, returning quarterly inflation to close to ...

The Evolution of Short-Run r* after the Pandemic
This post discusses the evolution of the short-run natural rate of interest, or short-run r*, over the past year and a half according to the New York Fed DSGE model, and the implications of this evolution for inflation and output projections. We show that, from the model’s perspective, short-run r* has increased notably over the past year, to some extent outpacing the large increase in the policy rate. One implication of these findings is that the drag on the economy from recent monetary policy tightening may have been limited, rationalizing why economic conditions have remained relatively ...

Disinflation Policies with a Flat Phillips Curve
Yesterday’s post analyzed the drivers of the surge in inflation over the course of 2021 through the lens of the New York Fed DSGE model. In today’s post, we use the model to study how alternative monetary policy strategies might contribute to bringing inflation back down to 2 percent. Our main finding is that there is no monetary silver bullet. Due to a flat Phillips curve—a well–documented feature of the economic environment of the last three decades—monetary policy can only achieve faster disinflation at a considerable cost in terms of forgone economic activity. This is true ...
