Import tariff transmission in a production network
We find that whether US import tariffs have supply-side effects or demand-side effects on US manufacturing sectors depends on where the affected sectors are located in the US production network. Using local projections in a panel of US manufacturing sectors, we find that US import tariffs —including the 2018-19 tariff hikes— led to sectoral output contractions via two different channels: (1) Tariff increases act as negative supply shifters for sectors that use goods from tariff-facing sectors as input in production and thus face rising input costs.
