The Welfare Effects of Social Media

Hunt Allcott, Luca Braghieri, Sarah Eichmeyer, Matthew Gentzkow

Published March 2020 · American Economic Review · Journal article

Summary

The authors ran a randomized experiment in which participants were paid to deactivate their Facebook accounts for four weeks before the 2018 US midterm elections. Deactivation reduced time online, increased offline socializing and TV watching, lowered factual news knowledge and political polarization, and modestly improved self-reported well-being. After the experiment, participants reduced their Facebook use, and many lowered their valuation of the platform, suggesting that habitual use exceeds its private benefits for some users.

Key findings

  • Four weeks of Facebook deactivation increased subjective well-being and freed up time reallocated to offline activities.
  • Deactivation reduced both factual news knowledge and measured political polarization.
  • Post-experiment, treated users used Facebook less and many revised their willingness-to-pay valuation of it downward.

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.
