MIT Study: Firms Use Automation to Suppress Wages, Boosting Inequality

A new study by MIT economists Daron Acemoglu and Pascual Restrepo reveals that US companies frequently utilize automation not to maximize productivity, but to replace workers earning a wage premium. Analyzing data from 1980 to 2016, the researchers found that this strategy targets non-college-educated employees who previously commanded higher salaries than their peers. Consequently, automation has significantly exacerbated income inequality, accounting for 52 percent of its growth during the studied period. Specifically, the replacement of premium-wage workers contributed about 10 percentage points to this disparity. Furthermore, this inefficient targeting of labor has offset 60-90 percent of potential productivity gains, explaining why US productivity statistics remain muted despite technological advancements. The findings, published in the Quarterly Journal of Economics, suggest that firms prioritize short-term wage control over long-term efficiency and growth. This dynamic highlights a critical misalignment between technological adoption and economic optimization, indicating that automation serves as a tool for rent dissipation rather than genuine productive enhancement in many US industries.
