The Employment and Wage Effects of Trump’s Steel Tariffs: A Review of Research Findings
Executive Summary
Research on the Trump administration’s 2018-2020 steel tariffs reveals significant negative net employment effects despite modest gains in steel production jobs. While steel workers experienced some wage increases, the broader economic impact included substantial job losses in steel-using industries and higher costs for consumers.
Background
The Trump administration imposed tariffs of 25% on steel imports and 10% on aluminum imports in March 2018 under Section 232 of the Trade Expansion Act of 1962, citing national security concerns. These tariffs remained in place through 2020 and have been the subject of extensive economic research.
Employment Effects
Steel Production Jobs
The tariffs had a modest positive effect on employment within the steel production sector itself. Research by Cox and Russ found that tariffs on steel led to an increase of roughly 1,000 jobs in steel production (Econofact, 2020). The latest data on steel production jobs showed roughly 1,000 more jobs in November 2019 than in March 2018 when the tariffs were implemented.
However, this gain was limited by structural factors in the industry. Even with demand strengthening, the effect on employment in steel production was likely to be muted by technological innovation, as new technologies have allowed steel companies to produce more with fewer workers (PBS NewsHour, 2020).
Steel-Using Industries
The employment losses in steel-consuming industries far exceeded gains in steel production. Cox and Russ estimated that increased costs facing U.S. firms due to the Section 232 tariffs on steel and aluminum likely resulted in 75,000 fewer manufacturing jobs in firms where steel or aluminum are inputs into production (Econofact, 2020). This disparity reflects the fundamental economic reality that steel-consuming jobs outnumber steel-producing jobs by 80 to 1 (Tax Foundation, 2024).
The automotive industry was particularly affected. All three Detroit automakers—General Motors, Ford, and Fiat Chrysler—closed plants in Michigan since January 2018. Both General Motors and Ford reported $1 billion each in increased steel costs in 2018 (NBC News, 2020).
Net Employment Impact
When accounting for both job gains and losses, the research suggests a negative net impact. Cox and Russ found that the broader trade war had caused a net loss of 175,000 U.S. manufacturing jobs by mid-2019 (Tax Foundation, 2024). Notably, the steel industry itself continued shedding jobs during the tariff period, employing 1,900 fewer workers than when Trump took office (NBC News, 2020).
Wage Effects
Steel Industry Wages
Workers in the protected steel industry did experience wage benefits. In late 2018, U.S. Steel workers secured a cumulative 14% wage increase over a four-year period (NBC News, 2020). These increases were supported by initially higher steel prices resulting from reduced foreign competition.
Broader Wage Impacts
However, the wage effects were not uniformly positive across the economy. Higher steel costs created pressure on wages and employment in downstream industries. Manufacturing costs remained elevated for companies like Ford, which purchases 95% of its steel from domestic suppliers (NBC News, 2020).
Economic Efficiency Analysis
Research suggests the job creation achieved through steel tariffs came at enormous cost. Studies indicate that American consumers paid approximately $900,000 in higher prices attributable to the tariffs for every job created in the steel industry (Brookings Institution, 2023). Similarly, tariffs on washing machines cost about $817,000 per job created.
The Brookings Institution concluded that when economists attempted to add up the net effect of Trump’s tariffs on jobs, any gains in import-competing sectors appeared to have been more than offset by losses in industries that use imported inputs and face retaliation on their foreign exports (Kimbrough & Sala-i-Martin, 2023).
Academic Consensus
A March 2018 survey of 43 economic experts by Chicago Booth revealed that 0% thought a U.S. tariff on steel and aluminum would improve Americans’ welfare (Tax Foundation, 2024). This reflects the broad academic consensus that while tariffs may benefit specific protected industries, they typically impose larger costs on the broader economy.
Conclusion
The research evidence on Trump’s steel tariffs demonstrates the classic trade-off inherent in protectionist policies: while they can provide benefits to workers in protected industries through higher wages and some job preservation, these gains typically come at the expense of much larger losses in downstream industries and higher costs for consumers. The net employment effect was negative, with job losses in steel-using industries far exceeding gains in steel production.
