We study the effects of unexpected changes in trade policy uncertainty (T P U ) on the U.S. economy. We construct three measures of T P U based on newspaper coverage, firms' earnings conference calls, and aggregate data on tariff rates. We document that increases in T P U reduce investment and activity using both firm-level and aggregate macroeconomic data. We interpret the empirical results through the lens of a two-country general equilibrium model with nominal rigidities and firms' export participation decisions. In the model as in the data, news and increased uncertainty about higher future tariffs reduce investment and activity.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
