Seeing Through the Shutdown’s Missing Inflation Data
Data releases for inflation have been scarce over the past four months due to the government shutdown. As a result, until January 22 no personal consumer expenditures (PCE) data were available beyond September and the consumer price index (CPI) had many missing entries for the one-month changes for October and November. In this post, we use an extended version of the New York Fed’s Multivariate Core Trend (MCT) inflation model to examine changes in underlying inflation over this period. The MCT model is well-suited to do so because it decomposes sectoral inflation rates into a trend (“persistent”) and a transitory component. In contrast to core (ex-food and energy) inflation, its aim is to remove all transitory factors, thus identifying the underlying trend. In addition, since the model can handle missing data—like for October—it can produce values for trend inflation for months where little or no data were released. Our findings suggest caution: while the fragmented data from November initially signaled a deceleration in price pressures, the integration of December data indicates that these reductions were largely transitory. Once the full data set is used, the aggregate trend for December stands at 2.83 percent, an increase from 2.55 percent in September.

Where Are Mortgage Delinquencies Rising the Most?
The Federal Reserve Bank of New York’s Center for Microeconomic Data recently released its Quarterly Report on Household Debt and Credit for the fourth quarter of 2025, revealing continued growth in household debt balances. Aggregate household debt balances rose by $191 billion to reach $18.8 trillion, marking a $4.6 trillion increase since the end of 2019. Mortgage balances grew by $98 billion to $13.2 trillion, while credit card debt increased by $44 billion to $1.28 trillion. Credit card and auto loan delinquency rates appear to have stabilized, albeit at elevated rates. By contrast, the delinquency rate for mortgages—although still near low levels on a longer-term basis—has been steadily increasing over the past few years. Underlying these aggregate figures, however, there are notable differences in mortgage credit performance across places with different income levels and labor and housing market dynamics. This analysis, as well as the Quarterly Report on Household Debt and Credit, are based on anonymous credit report data from Equifax.

Does the Phillips Curve Steepen When Costs Surge?
Inflation does not always respond to cost and demand pressures in the same way. When shocks are small, the mapping from costs to prices is roughly proportional—double the shock, double the inflation response. But when the economy is hit by large shocks, this proportionality breaks down. As the recent surge and subsequent decline of global inflation showed, price growth can accelerate—or decelerate—by more than one-for-one relative to the size of the disturbance. Economists refer to this pattern as nonlinear inflation dynamics. In this post, I discuss what these nonlinearities mean, how they relate to the slope of the Phillips curve discussed in a companion post, and how firm-level data can help us understand the mechanisms behind them.

Anatomy (not Autopsy) of the Phillips Curve
The relationship between inflation and real economic activity has long been central to debates in macroeconomics and monetary policy. At the core of this debate is the Phillips curve (PC), which measures how strongly inflation reacts to movements in economic conditions. The steepness of this curve matters enormously for monetary policy: if the PC is steeper, inflation rises faster during booms and falls faster in recessions, which entails central banks having to act more forcefully if they want to stabilize inflation around their target. Prior analysis found astonishingly small estimates of the slope of the PC, which suggests that the curve is “flat” (or even dead). In this post, I present evidence from coauthored research showing that, contrary to the conventional view, the Phillips curve is alive and steep, and it captures inflation volatility remarkably well once real marginal cost is used instead of standard real economic activity measures.

New York Fed EHIs Reveal Small Business Struggles
The New York Fed’s Economic Heterogeneity Indicators (EHIs) aim to study macroeconomic outcomes experienced by various groups of people and businesses. We recently added a suite of indicators describing the performance of small businesses to the EHIs—both for the region (defined, for the purpose of this study, as New York, New Jersey, and Connecticut) and nationally. Small businesses are critical to employment generation as they accounted for almost 63 percent of new private sector jobs since 2005 and employed almost 46 percent of all U.S. workers in 2025. Thus, understanding economic trends and impacts for small businesses is important for designing effective monetary policy and aligns with the New York Fed’s mission to support the regional economy. In this post, we highlight some aspects of small business profitability, revenues, employment, and indebtedness since 2019 for firms of different sizes.

A New Dataset for Consumer Spending in the New York Fed EHIs
We are enhancing our set of Economic Heterogeneity Indicators (EHIs) by adding a set of metrics on consumer spending with data presented by income, education, race and ethnicity, age, and urban status. The data will help track the evolution of aggregate behavior by analyzing the spending of specific groups in a more timely manner than is possible using public surveys.

Understating Rising Quality Means Import Price Inflation Is Overstated
It is common for price measures to consider changes in quality. That is, a price index might fall even though listed prices are unchanged because the quality of the item has improved. An adjustment for quality captures the fact that consumers are effectively getting more for the same dollar when product quality rises. In practice, however, it is notoriously difficult to measure quality changes since it requires access to detailed data on all product characteristics that matter to consumers. We offer a novel method to infer quality changes and apply it to U.S. import price indices. When we account for quality improvements in this way, we find that the import price inflation based on official measures has been overstated, revealing that consumers have been getting more from their purchases of imported goods than what standard quality adjustments suggest.

Measuring Labor Market Tightness: Data Update and New Web Feature
Good measures of labor market tightness are essential to predict wage inflation and to calibrate monetary policy. In an October 2024 post, we introduced a new indicator of labor market tightness and showed that it tracked wage inflation best out of a broad range of tightness measures. In this post, we update our index through 2025 and show that it also forecasts future wage inflation best both in and out of sample. In addition, we highlight availability of the index as a new regularly updated feature on the New York Fed’s website.

What Can Undermine a Carbon Tax?
Several countries have implemented a carbon tax or cap-and-trade system to establish high carbon prices and create a disincentive for the use of fossil fuels. Essentially, the tax encourages firms to substitute toward low carbon emission energy. Costs also rise for firms down the supply chain that use production inputs with high-emission content, so the total impact of a carbon tax can be large. In practice, however, firms also have an incentive to find an offset to a carbon tax. In this post, based on our recent work, we present evidence of one such adaptation strategy. We show that French firms increased their imports of high-emission inputs from suppliers outside the European Union’s cap-and-trade system, known as the EU Emissions Trading System (EU ETS), reducing the effectiveness of this approach to cutting carbon emissions—an adaptation strategy that leads to “carbon leakage.” To help stop this leakage, the EU is implementing a “carbon tariff” in 2026, which is the topic of a companion post.

Which Entrepreneurs Boost Productivity?
Why do some entrepreneurs drive economic growth while others do not? This piece discusses new work that studies entrepreneurs using a comprehensive dataset from Denmark. We study who becomes an entrepreneur, along with their hiring and business decisions, and find that a distinct minority are “transformative.” These individuals, who generate disproportionate productivity gains, tend to have high IQ scores, be well-educated, and hire technical (R&D) workers. The data support the idea of productivity growth being driven by the symbiotic relationship between transformative entrepreneurs and R&D workers. For policymakers, the lesson is that when an economy has more R&D workers and transformative entrepreneurs, they sustain higher long-run productivity growth.
