“This is going to be much bigger than Smoot-Hawley,” says Douglas Irwin, an economic historian at Dartmouth College, who points to both the expected leap in tariff rates and the amount of trade covered as likely to eclipse what happened in 1930. “Imports are a much greater share of GDP now than they were back in the early 1930s by a long shot.” Imports of goods and services are 14% of US gross domestic product — about triple the share they accounted for in 1930.
