What the study found
The study finds that automation in a task-based economy tends to target high-rent tasks, meaning tasks that pay wages above workers' outside options. The authors report that this dissipates rents, amplifies wage losses, and reduces within-group wage dispersion among exposed groups.
Why the authors say this matters
The authors conclude that this form of rent dissipation is inefficient and offsets the productivity gains from automation. They also say the findings help explain wage inequality patterns, including between-group inequality and wage dispersion within groups.
What the researchers tested
The researchers studied automation in a task-based economy where some jobs pay rent, meaning wages above workers' outside options. They used U.S. data from 1980 to 2016 to examine how automation relates to wages, inequality, productivity, and rent dissipation.
What worked and what didn't
The authors find 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 this total. They also estimate that inefficient rent dissipation offset 60% to 90% of the productivity gains from automation over the period studied.
What to keep in mind
The abstract describes findings for the U.S. from 1980 to 2016, so the results are limited to that setting and time period. The abstract does not describe additional limitations beyond the study's focus on a task-based economy and the measured relationships in the available data.
Key points
- Automation in the model targets high-rent tasks, not just tasks in general.
- Rent dissipation is described as inefficient and as offsetting productivity gains.
- Using U.S. data from 1980 to 2016, the authors find evidence of sizable rent dissipation.
- Automation accounts for 52% of the rise in between-group inequality since 1980.
- Rent dissipation explains one-fifth of that inequality increase.
- The authors estimate that 60% to 90% of automation's productivity gains were offset.
