Study finds automation often targets higher-paid workers, impacting wages and productivity
May 7, 2026
AI Summary
A study co-authored by an MIT economist reveals that since 1980, automation in the U.S. has frequently been used by firms to replace higher-paid workers, particularly those without college degrees. This practice has contributed significantly to income inequality and has limited productivity gains, as firms prioritize wage control over efficiency improvements.
- The study indicates that automation has been used to replace employees earning a wage premium, particularly affecting non-college-educated workers with higher salaries than their peers.
- It estimates that automation accounts for 52% of the growth in income inequality from 1980 to 2016, with 10 percentage points specifically linked to the replacement of higher-paid workers.
- The research suggests that this targeting of automation has offset 60-90% of productivity gains expected from technological advancements.
- The analysis involved data from various sources, including U.S. Census Bureau statistics, and examined 500 demographic groups across 49 industries.
- The findings show that the most significant impacts of automation are felt among workers in the 70th-95th salary percentiles, indicating that higher earners are disproportionately affected.
- The study highlights a disconnect between profitability and productivity, suggesting that firms may prioritize cost reduction over efficiency, leading to muted overall productivity improvements in the U.S. economy.
- The authors call for a reevaluation of how automation is implemented to enhance productivity and address inequality more effectively.
