Rethinking Inequality Through the Lens of Market Power

Jonathan Becker is part of a new generation of economists working to understand how markets shape people's day-to-day lives. An assistant professor in the Department of Economics at the State University of New York at Stony Brook, Becker studies macroeconomics, inequality and firm behavior, with a particular focus on market power, or the ability of firms to raise prices when consumers lack strong alternatives.

While the concept is straightforward, Becker's research shows that its real-world effects are far more complex. Market power does not simply shift income toward firm owners. It interacts with inequality in ways that reinforce both. As inequality rises, markets become more segmented, with fewer consumers able to move between low- and high-quality goods. That reduced mobility weakens competition, allowing firms across the spectrum to charge higher markups. The result is a feedback loop in which inequality and market power deepen one another over time.

Becker's path into this work reflects a shift from finance to fundamental economic questions. He studied financial economics at Oxford with plans to pursue quantitative trading but became more interested in the broader forces shaping markets and economic outcomes. He went on to complete his PhD at New York University, where he focused on macroeconomics while continuing to draw on his finance background. That combination informs a research agenda that pairs rigorous modeling with detailed empirical data.

A central theme in Becker's work is that different households experience the same economy in very different ways. Standard indicators such as average inflation or income often obscure these differences. Two households may live through the same recession, but the prices they face, the goods they depend on, and the alternatives available to them can vary significantly.

This variation becomes especially important during economic downturns. Becker often points to how consumers "trade down" during recessions, shifting toward cheaper goods. As demand concentrates in lower-priced segments, competition within those segments weakens. Firms gain greater pricing power, which can raise effective costs for lower-income households. Recessions, in this sense, do more than reduce overall spending. They reshape market dynamics in ways that disproportionately affect the most vulnerable consumers.

To study these dynamics, Becker relies on highly detailed data at both the household and firm levels. On the household side, he uses datasets that track individual purchasing behavior down to specific items and prices. On the firm side, he examines production, trade flows, and market structure. By combining these sources, he builds quantitative models that simulate how economic changes affect different groups. These models allow him to test scenarios that cannot be observed directly, offering a clearer view of how policy or market shifts ripple through the economy.

Geography adds another layer to this analysis. Becker's research shows that markets are less integrated than many traditional models assume. A household's location can shape the level of competition it faces, the prices it pays, and the range of goods available. Smaller or more isolated areas often experience weaker competition and higher costs, reinforcing disparities across regions.

At Stony Brook, Becker contributes to a collaborative research environment that reflects his interdisciplinary approach. He helps organize the department's integrated seminar series alongside colleague Lorenz Ekerdt, bringing together macroeconomics, microeconomics, and econometrics in a single weekly forum. The structure encourages researchers to engage across subfields and approach economic questions from multiple perspectives.

That emphasis on dialogue carries into his broader work. Becker often develops research ideas through conversations that connect theory with real-world observations. In both his teaching and scholarship, he prioritizes starting with concrete economic questions and using models as tools to clarify the underlying mechanisms.

Looking ahead, Becker plans to continue examining the relationship between market power and inequality while expanding into new areas that draw more directly on his background in finance. As access to detailed data continues to grow, he sees increasing opportunities to better capture the diversity of economic experiences across households and firms.

For Becker, economics is ultimately about understanding how markets shape lived experience. His work challenges the assumption that averages tell the whole story, instead pointing toward a more precise and grounded view of how the economy functions for different people.
