Abstract

We examine the impacts of the 2018–2019 U.S. import tariff increases on U.S. exports through the lens of supply chain linkages. Using 2016 confidential firmtrade linked data, we identify exporters importing products that eventually faced tariff increases to construct product level exposure to import tariffs. We find that the most exposed products had lower exports in 2018–2019, with largest effects in 2019. The decline in exports in 2019 is equivalent to an ad valorem tariff on U.S. exports of 2% to 4%.
