A U.S. Department of Commerce document lists Purdue University research as a source for recommending a 24 percent tariff on imported steel.
When Purdue agricultural economics professor Thomas Hertel first saw the Trump Administration’s math, he had to check for himself.
“We quickly re-ran that experiment here and we get the same outcome,” says Hertel.
He created the Global Trade Analysis Project Model, referred to as GTAP, 25 years ago. The free database runs analyses on the impacts of tariffs and today has more than 17,000 users in 170 countries.
