Global Trends in U.S. Inflation Dynamics
A key feature of the post-pandemic inflation surge was the strong correlation among inflation rates across sectors in the United States. This phenomenon, however, was not confined to the U.S. economy, as similar inflationary pressures have emerged in other advanced economies. As generalized as the inflation surge was, so was its decline from the mid-2022 peak. This post explores the common features of inflation patterns in the U.S. and abroad using an extension of the Multivariate Core Trend (MCT) Inflation model, our underlying inflation tracker for the U.S. The Global MCT model purges transitory noise from international sectoral inflation data and quantifies the covariation of their persistent components—in the form of global inflation trends—along both country and sectoral dimensions. We find that global trends play a dominant role in determining the slow-moving and persistent dynamics of headline consumer price index (CPI) inflation in the U.S. and abroad, both over the pre-pandemic and post pandemic samples.

A New Indicator of Labor Market Tightness for Predicting Wage Inflation
A key question in economic policy is how labor market tightness affects wage inflation and ultimately prices. In this post, we highlight the importance of two measures of tightness in determining wage growth: the quits rate, and vacancies per searcher (V/S)—where searchers include both employed and non-employed job seekers. Amongst a broad set of indicators, we find that these two measures are independently the most strongly correlated with wage inflation. We construct a new index, called the Heise-Pearce-Weber (HPW) Tightness Index, which is a composite of quits and vacancies per searcher, and show that it performs best of all in explaining U.S. wage growth, including over the COVID pandemic and recovery.

Can Professional Forecasters Predict Uncertain Times?
Economic surveys are very popular these days and for a good reason. They tell us how the folks being surveyed—professional forecasters, households, firm managers—feel about the economy. So, for instance, the New York Fed’s Survey of Consumer Expectations (SCE) website displays an inflation uncertainty measure that tells us households are more uncertain about inflation than they were pre-COVID, but a bit less than they were a few months ago. The Philadelphia Fed’s Survey of Professional Forecasters (SPF) tells us that forecasters believed last May that there was a lower risk of negative 2024 real GDP growth than there was last February. The question addressed in this post is: Does this information actually have any predictive content? Specifically, I will focus on the SPF and ask: When professional forecasters indicate that their uncertainty about future output or inflation is higher, does that mean that output or inflation is actually becoming more uncertain, in the sense that the SPF will have a harder time predicting these variables?

Are Professional Forecasters Overconfident?
The post-COVID years have not been kind to professional forecasters, whether from the private sector or policy institutions: their forecast errors for both output growth and inflation have increased dramatically relative to pre-COVID (see Figure 1 in this paper). In this two-post series we ask: First, are forecasters aware of their own fallibility? That is, when they provide measures of the uncertainty around their forecasts, are such measures on average in line with the size of the prediction errors they make? Second, can forecasters predict uncertain times? That is, does their own assessment of uncertainty change on par with changes in their forecasting ability? As we will see, the answer to both questions sheds light of whether forecasters are rational. And the answer to both questions is “no” for horizons longer than one year but is perhaps surprisingly “yes” for shorter-run forecasts.

What Was Up with Grocery Prices?
The consumer price index for groceries has risen more than the overall price index since the start of the pandemic, with a particularly large jump in 2022. In looking for explanations, a starting place is the behavior of raw commodity prices, which surged from early 2021 to mid-2022. In addition, wages for low-paid grocery workers have gone up faster than wages for the workforce as a whole. Finally, even though profit margins for grocery stores have gone up, the increase appears to be only a small contributor to the rise in food prices relative to the increase in their operating costs. This analysis suggests that the significant moderation in food inflation since the start of 2023 is due to still-high wage inflation for grocery workers being offset by the retreat in commodity prices.

On the Distributional Consequences of Responding Aggressively to Inflation
This post discusses the distributional consequences of an aggressive policy response to inflation using a Heterogeneous Agent New Keynesian (HANK) model. We find that, when facing demand shocks, stabilizing inflation and real activity go hand in hand, with very large benefits for households at the bottom of the wealth distribution. The converse is true however when facing supply shocks: stabilizing inflation makes real outcomes more volatile, especially for poorer households. We conclude that distributional considerations make it much more important for policy to take into account the tradeoffs between stabilizing inflation and economic activity. This is because the optimal policy response depends very strongly on whether these tradeoffs are present (that is, when the economy is facing supply shocks) or absent (when the economy is facing demand shocks).

On the Distributional Effects of Inflation and Inflation Stabilization
This post and the next discuss the distributional effects of inflation and inflation stabilization through the lenses of a theoretical model—a Heterogeneous Agent New Keynesian (HANK) model. This model combines the features of New Keynesian models that have been the workhorse for monetary policy analysis since the work of Woodford (2003) with inequality in wealth and income at the household level following the seminal contribution of Kaplan, Moll, and Violante (2018). We find that while inflation hurts everyone, it hurts the poor in particular. When the source of inflation is a supply shock, fighting inflation aggressively hurts the poor even more, however, while the opposite is true for demand shocks, as discussed in the companion post.

Deciphering the Disinflation Process
U.S. inflation surged in the early post-COVID period, driven by several economic shocks such as supply chain disruptions and labor supply constraints. Following its peak at 6.6 percent in September 2022, core consumer price index (CPI) inflation has come down rapidly over the last two years, falling to 3.6 percent recently. What explains the rapid shifts in U.S. inflation dynamics? In a recent paper, we show that the interaction between supply chain pressures and labor market tightness amplified the inflation surge in 2021. In this post, we argue that these same forces that drove the nonlinear rise in inflation have worked in reverse since late 2022, accelerating the disinflationary process. The current episode contrasts with periods where the economy was hit by shocks to either imported inputs or to labor alone.

Is the Recent Inflationary Spike a Global Phenomenon?
In the aftermath of the COVID-19 pandemic, inflation rose almost simultaneously in most economies around the world. After peaking in mid-2022, inflation then went into decline—a fall that was just as universal as the initial rise. In this post, we explore the interrelation of inflation dynamics across OECD countries by constructing a measure of the persistence of global inflation. We then study the extent to which the persistence of global inflation reflects broad-based swings, as opposed to idiosyncratic country-level movements. Our main finding is that the spike and subsequent moderation in global inflation in the post-pandemic period were driven by persistent movements. When we look at measures of inflation that include food and energy prices, most of the persistence appears to be broad-based, suggesting that international oil and commodity prices played an important role in global inflation dynamics. Excluding food and energy prices in the analysis still shows a broad-based persistence, although with a substantial increase in the role of country-specific factors.

Do Unexpected Inflationary Shocks Raise Workers’ Wages?
The past year’s steady decline in nominal wage growth now appears in danger of stalling. Given ongoing uncertainty in Ukraine and the Middle East, this seems an opportune moment to revisit the conventional wisdom about the relationship between inflation and wages: if an unexpected increase in energy costs drives up the cost of living, will workers demand higher wages, reversing the recent moderation in wage growth? In new work with Justin Bloesch and Seung Joo Lee examining those concerns, our analysis shows that the pass-through of such inflationary shocks to wages is weak.
