In the realm of economic discussions, few topics resonate as personally with the average American as the price of groceries.

Paul Krugman is an American economist, distinguished professor, and author known for his work in international economics and his commentary on economic policy. Born on February 28, 1953, Krugman has made significant contributions to the fields of international trade and finance, economic geography, and liquidity traps. He was awarded the Nobel Memorial Prize in Economic Sciences in 2008 for his analysis of trade patterns and location of economic activity.

Krugman has been a vocal and influential figure in public debates on economic policy, globalization, and the welfare state. He is well-known for his op-ed column in The New York Times, where he discusses economic and political issues from a liberal perspective. Krugman has also authored or co-authored numerous books on economics, including “The Age of Diminished Expectations,” “The Return of Depression Economics,” and “End This Depression Now!”

Before his tenure at The New York Times, Krugman taught at several prestigious institutions, including the Massachusetts Institute of Technology (MIT), Stanford University, and Princeton University. As of my last update, he is a professor of economics and international affairs at the Graduate Center of the City University of New York, in addition to his continued role as a columnist and commentator.

On February 23, Krugman took to social media platform X to address a pervasive narrative: the claim that grocery prices have doubled and are continuing to soar.

Leveraging a chart from the Federal Reserve Economic Data (FRED), Krugman highlighted that, contrary to widespread belief, the increase in U.S. food prices, particularly for groceries intended for home consumption, has been significant but not as drastic as many assert.

The FRED Chart: A Closer Look at “Food at Home” CPI Data

FRED, maintained by the Federal Reserve Bank of St. Louis, offers a treasure trove of economic data, including the Consumer Price Index (CPI) for All Urban Consumers. This index, a critical measure of inflation, includes a category specifically tracking “Food at Home” prices across U.S. cities. The CPI for “Food at Home” reflects the cost changes over time for groceries purchased for consumption at home, providing a clear picture of how food price trends affect household budgets.

The chart cited by Krugman spans the past four years, a period marked by economic upheavals, including the COVID-19 pandemic and subsequent recovery phases. According to the data, the CPI for “Food at Home in US City Average” rose from approximately 301 in January 2023 to 307 in January 2024. This increment, while indicative of inflation in grocery prices, challenges the hyperbolic narrative that prices have doubled or are in an uncontrolled ascent.

Analyzing the Data: What Does It Tell Us?

The modest increase in the “Food at Home” CPI suggests several key insights:

  1. Perception vs. Reality: The public perception of grocery prices doubling is not supported by the data. While prices have indeed risen, the scale of increase is far from the doubling that some claim.
  2. Inflation’s Impact: The data confirms that grocery prices are subject to inflationary pressures, as seen in the gradual rise over the past four years. However, the rate of increase is relatively controlled, reflecting both the resilience and challenges within the U.S. food supply chain.
  3. Economic Context: The period in question has been tumultuous, with the pandemic affecting supply chains, labor markets, and consumer demand. Despite these challenges, the grocery price increase has been moderate, suggesting effective mitigations and adaptations by the food industry and policymakers.

Beyond the Numbers: Understanding Grocery Price Dynamics

The FRED data on “Food at Home” CPI provides a factual basis to counter exaggerated claims about grocery price inflation. However, it’s essential to recognize that even moderate inflation can strain household budgets, particularly for low-income families. The economic context, including wage growth and employment rates, plays a crucial role in how inflation affects consumers.

Moreover, regional variations in food prices and the impact of global events on commodities like wheat and oil can influence grocery costs. As such, while the national average offers a broad perspective, individual experiences with grocery shopping may vary.

Krugman’s View of the Current State of the U.S. Economy

In light of the discussions surrounding grocery prices and inflation, it’s imperative to broaden our perspective by examining the broader economic indicators that shape our understanding of inflation. This becomes particularly relevant when considering the insights shared by Paul Krugman in a New York Times opinion piece on February 22, following the release of the January 2024 Consumer Price Index (CPI) and Producer Price Index (PPI) data by the U.S. Bureau of Labor Statistics.

Krugman’s analysis in this article — which was praising Bidenomics — set against the backdrop of a 0.3 percent rise in both CPI and PPI for January 2024, challenges the narrative of runaway inflation. This data, which exceeded many analysts’ expectations, sparked a wave of reactions from various quarters, including those skeptical of inflation, critics of the Biden administration, and economists who had previously argued that reducing inflation would necessitate significant unemployment. Contrary to these reactions, Krugman posits that the January figures represent a statistical anomaly rather than a substantive shift in inflationary trends.

To support his argument, Krugman highlights two pivotal indicators. First, he notes the financial markets’ continued expectation of controlled inflation levels, around 2 percent, as evidenced by inflation swaps and index bonds. Second, the Atlanta Federal Reserve’s survey of business inflation expectations, which showed a minimal increase from 2.2 percent in January to 2.3 percent in February, suggests that businesses do not perceive a sudden surge in inflation.

Furthermore, Krugman delves into the complexities of calculating the CPI, acknowledging the Bureau of Labor Statistics’ expertise but also noting potential distortions. One such distortion is the “January effect,” where the beginning of the year sees many companies adjusting prices, potentially leading to an overstated inflation reading for January.

Additionally, Krugman critiques the CPI’s reliance on “owners’ equivalent rent,” which significantly influences the index but may not accurately reflect real housing costs. He suggests that excluding this component reveals a more modest inflation increase, aligning more closely with European methods of measuring inflation.
