Automation lowers rents and widens inequality less within groups

What the study found

Automation targets high-rent tasks in a task-based economy where some jobs pay workers rents, meaning wages above outside options. The authors find that this dissipates rents, amplifies wage losses, and reduces within-group wage dispersion in exposed groups.

Why the authors say this matters

The study suggests that this rent dissipation is inefficient and offsets the productivity gains from automation. The authors also conclude that automation has contributed to wage inequality over time.

What the researchers tested

The article studies automation in a task-based economy with jobs that can pay rents. It uses U.S. data from 1980 to 2016 to assess effects on wages, inequality, productivity, and within-group wage dispersion.

What worked and what didn't

The authors report evidence of sizable rent dissipation and reduced within-group wage dispersion due to automation. They estimate that automation accounts for 52% of the increase in between-group inequality since 1980, with rent dissipation explaining one-fifth of that total, and that inefficient rent dissipation has offset 60%–90% of productivity gains from automation over the period.

What to keep in mind

The abstract does not provide detailed limitations beyond the study's focus on a task-based economy and U.S. data from 1980 to 2016. The estimates and shares reported are specific to that setting and period.

Key points

  • Automation targets high-rent tasks and dissipates rents in the model studied.
  • The authors find automation amplifies wage losses and reduces within-group wage dispersion in exposed groups.
  • Using U.S. data from 1980 to 2016, the study finds evidence of sizable rent dissipation.
  • Automation accounts for 52% of the increase in between-group inequality since 1980.
  • The authors estimate that inefficient rent dissipation offset 60%–90% of productivity gains from automation.
