The Regional Side of the Story: K‑Shaped Pattern in Region, Wider Gap in Gas Spending

split image of two women: on the left an African American woman with cell phone boarding a bus; on the right, a Causasian woman leaning on a fancy red car looking at her cell phone and holding a coffee cup. She is at a gas statiion and the gas pumps are in the background.

In this post, we use the inaugural release of our regional consumer spending indicators to ask whether these patterns hold for a significant portion of the Second District, and how regional spending patterns by income have been similar to or different from the national patterns we documented earlier. We find similar K‑shaped patterns in both retail and gas spending in our region as we do in the nation, with the K‑shaped pattern in gasoline in response to the recent gas price shock being more pronounced in the region.

Explaining the K‑Shaped Economy: What’s Behind the Divide?

In our companion post, we used a new module of our Economic Heterogeneity Indicators (EHIs) to shed light on how recent retail spending growth has been driven by high-income households. This fact is consistent with the popular press’s idea of a “K-shaped economy” in which higher-income households experience faster growth in spending than lower-income households. In this post, we dive deeper into the reasons behind this divergence by analyzing for which goods this trend holds true and ask whether it can be explained by changes in wages, inflation, or wealth. We find that, since 2023, wealth has increased the most for high-income households, while inflation has risen the most for low-income households, with both factors helping explain the fact that real retail spending rose the most for high-income households. In contrast, earnings display a more mixed pattern, though earnings of the highest earners have grown more rapidly than earnings of the lowest earners.

Tracking the K‑Shaped Economy: Who’s Driving Spending?

Shopping Spree in Modern Retail Environment

Aggregate real consumer spending has risen solidly since 2023. However, it is less clear how widely shared this improvement has been across all segments of society. This is important because systematic heterogeneity may mask the dependence of aggregate growth on a relatively small group of households and thus conceal macroeconomic risks. In this post, we use consumer spending data recently added to the Economic Heterogeneity Indicators (EHIs) and find that retail spending growth has been driven by high-income households—those earning more than $125,000 per year. In the popular press, the phenomenon of higher-income households growing at a faster rate than lower-income households has been referred to as the K-shaped economy. We find that consumption has exhibited a K-shaped economy since 2023, although not in the pre-COVID period or during the post-COVID recovery.

The College Economy: Educational Differences in Labor Market Outcomes

It is intuitive that workers with higher levels of education tend to earn more than workers with less education. However, it is also true that workers with more education are much more likely to be employed, and this employment advantage of education has, if anything, grown in recent years. In this post, we document profound differences in labor market outcomes by educational attainment. Drawing on the Economic Heterogeneity Indicators, we find that the gap in employment rates between workers who have completed college and workers who have not is 12 percentage points—which is larger than the employment gaps between workers of different races/ethnicities or between men and women—and is wider than the pre-pandemic gap. Moreover, most of this gap and its recent movements are driven by differences in labor force participation rates rather than by differences in unemployment rates. Fostering higher labor force participation of workers without a college degree thus would be quite helpful in promoting maximum employment.
