The macroeconomics of trend inflation
Most macroeconomic models for monetary policy analysis are approximated around a zero inflation steady state, but most central banks target an inflation rate of about 2 percent. Many economists have recently proposed even higher inflation targets to reduce the incidence of the zero lower bound constraint on monetary policy. In this survey, we show that the conduct of monetary policy should be analyzed by appropriately accounting for the positive trend inflation targeted by policymakers. We first review empirical research on the evolution and dynamics of U.S. trend inflation and some proposed ...

Inflation persistence: alternative interpretations and policy implications
In this paper, I consider the policy implications of two alternative structural interpretations of observed inflation persistence, which correspond to two alternative specifications of the new Keynesian Phillips curve (NKPC). The first specification allows for some degree of intrinsic persistence by way of a lagged inflation term in the NKPC. The second is a purely forward-looking model, in which expectations farther into the future matter and coefficients are time-varying. In this specification, most of the observed inflation persistence is attributed to fluctuations in the underlying ...

Forecasting with the FRBNY DSGE Model
The Federal Reserve Bank of New York (FRBNY) has built a DSGE model as part of its efforts to forecast the U.S. economy. On Liberty Street Economics, we are publishing a weeklong series to provide some background on the model and its use for policy analysis and forecasting, as well as its forecasting performance. In this post, we briefly discuss what DSGE models are, explain their usefulness as a forecasting tool, and preview the forthcoming pieces in this series.

Sources of New York employment fluctuations
The authors analyze employment growth in the metropolitan region and its relationship to employment in the United States as a whole. They identify a strong cyclical link between the region and the nation, punctuated by occasional, persistent shifts in the region's underlying growth rate. Some shifts are found to be related to industry factors, such as the restructuring of financial services in the late 1980s. However, the authors attribute a large and increasing share of New York employment fluctuations to region-specific factors.

Opening the Toolbox: The Nowcasting Code on GitHub
In April 2016, we unveiled--and began publishing weekly--the New York Fed Staff Nowcast, an estimate of GDP growth using an automated platform for tracking economic conditions in real time. Today we go a step further by publishing the MATLAB code for the nowcasting model, available here on GitHub, a public repository hosting service. We hope that sharing our code will make it easier for people interested in monitoring the macroeconomy to understand the details underlying the nowcast and to replicate our results.

The Layers of Inflation Persistence
In a recent post, we introduced the Multivariate Core Trend (MTC), a measure of inflation persistence in the core sectors of the personal consumption expenditure (PCE) price index. With data up to February 2022, we used the MCT to interpret the nature of post-pandemic price spikes, arguing that inflation dynamics were dominated by a persistent component largely common across sectors, which we estimated at around 5 percent. Indeed, over the year, inflation proved to be persistent and broad based, and core PCE inflation is likely to end 2022 near 5 percent. So, what is the MCT telling us today? ...

Trend inflation and inflation persistence in the New Keynesian Phillips curve
The New Keynesian Phillips curve (NKPC) asserts that inflation depends on expectations of real marginal costs, but empirical research has shown that purely forward-looking versions of the model generate too little inflation persistence. In this paper, we offer a resolution of the persistence problem. We hypothesize that inflation is highly persistent because of drift in trend inflation, a feature that many versions of the NKPC neglect. We derive a version of the NKPC as a log-linear approximation around a time-varying inflation trend and examine whether it explains deviations of inflation ...

Inflation Persistence: How Much Is There and Where Is It Coming From?
The surge in inflation since early 2021 has sparked intense debate. Would it be short-lived or prove to be persistent? Would it be concentrated within a few sectors or become broader? The answers to these questions are not so clear-cut. In our view, one should ask how much of the inflation is persistent and how much of it is broad-based. In this post, we address this question through a quantitative lens. We find that the large ups and downs in inflation over the course of 2020 were largely the result of transitory shocks, often sector-specific. In contrast, sometime in the fall of 2021, ...
