Abstract

Firms in regional trade areas choose whether to comply with rules of origin (RoO) or pay a tariff penalty. Stricter content requirements initially expand regional part sourcing, but contract it when set at levels above a threshold, analogously to the Laffer curve for taxes. We calibrate the model to fit part cost shares for autos sold in North America. The effects of the 75% RoO imposed in 2020 depend on the relevant tariff and the ability to relocate assembly. With fixed assembly locations, the higher RoO reduces employment in all three countries for cars, where tariffs are low. For trucks, the 25% US tariff induces more compliance in Canada and Mexico, increasing employment in those countries. With the option to relocate assembly, higher RoOs redistribute employment to the US, but Canada and Mexico lose more, leading to a half percent decline in North American employment for both cars and trucks.
