Trump’s Tariffs Hurt U.S. Jobs but Swayed American Voters, Study Says

The sweeping tariffs that former President Donald J. Trump imposed on China and other American trading partners were simultaneously a political success and an economic failure, a new study suggests. That’s because the levies won over voters for the Republican Party even though they did not bring back jobs.

The nonpartisan working paper examines monthly data on U.S. employment by industry to find that the tariffs that Mr. Trump placed on foreign metals, washing machines and an array of goods from China starting in 2018 neither raised nor lowered the overall number of jobs in the affected industries.

But the tariffs did incite other countries to impose their own retaliatory tariffs on American products, making them more expensive to sell overseas, and those levies had a negative effect on American jobs, the paper finds. That was particularly true in agriculture: Farmers who exported soybeans, cotton and sorghum to China were hit by Beijing’s decision to raise tariffs on those products to as much as 25 percent.

The Trump administration aimed to offset those losses by offering financial support for farmers, ultimately giving out $23 billion in 2018 and 2019. But those funds were distributed unevenly, a government assessment found, and the economists say those subsidies only partially mitigated the harm that had been caused by the tariffs.

The findings contradict Mr. Trump’s claims that his tariffs helped to reverse some of the damage done by competition from China and bring back American manufacturing jobs that had gone overseas. The economists conclude that the aggregate effect on U.S. jobs of the three measures — the original tariffs, retaliatory tariffs and subsidies granted to farmers — were “at best a wash, and it may have been mildly negative.”

“Certainly you can reject the hypothesis that this tariff policy was very successful at bringing back jobs to those industries that got a lot of exposure to that tariff war,” one of the study authors, David Dorn of the University of Zurich, said in an interview.
