The Rise of Market Power and the Macroeconomic Implications

Jan De Loecker, Jan Eeckhout, Gabriel Unger

Published May 2020 · The Quarterly Journal of Economics · Journal article

Summary

Using firm-level data for the U.S. economy since 1955, the authors estimate price-cost markups and document a sharp rise in aggregate market power beginning around 1980. They argue this increase in markups can account for several secular macroeconomic trends, including the declining labor and capital shares and reduced labor-market dynamism.

Key findings

  • Average markups rose from about 21% over marginal cost in 1980 to roughly 61% by 2016.
  • The rise is concentrated in the upper tail of the markup distribution, while the median firm's markup changed little.
  • Rising market power offers a unified explanation for falling labor and capital shares, lower low-skill wages, and declining business dynamism.

Social Capital I: Measurement and Associations with Economic Mobility

Raj Chetty, Matthew O. Jackson, Theresa Kuchler and Johannes Stroebel

Using data on 21 billion Facebook friendships, the authors construct ZIP-code-level measures of three distinct forms of social capital: cross-class connectedness, social cohesion, and civic engagement. They show these measures vary widely across areas and are only weakly correlated with one another. They find that economic connectedness between low- and high-income people is strongly associated with upward income mobility, more so than other forms of social capital.

Imperfect Competition, Compensating Differentials, and Rent Sharing in the US Labor Market

Thibaut Lamadon, Magne Mogstad and Bradley Setzler

The authors build and estimate an equilibrium model of imperfect competition in the US labor market using linked employer-employee administrative data, combining firm-level productivity shocks with worker mobility. They quantify the degree of employer wage-setting power (monopsony), how firms share rents with workers, and the role of compensating differentials for non-wage amenities. They find that firms have substantial market power and pass through only part of productivity gains to wages, while amenities matter for worker sorting.

Difference-in-Differences with Multiple Time Periods

Brantly Callaway and Pedro H. C. Sant'Anna

The paper develops a framework for difference-in-differences designs in which units adopt treatment at different times across multiple periods. It defines group-time average treatment effects and shows how to identify and estimate them under conditional parallel trends, then aggregate them into interpretable summary parameters. The authors provide valid simultaneous inference and apply the methods to estimating the effect of minimum wage increases on teen employment.
