We study the relationship between tariffs and labor productivity in US manufacturing between 1870 and 1909. Using highly dis-aggregated tariff data, state-industry data for the manufacturing sector, and an instrumental variable strategy, results show that tariffs reduced labor productivity....

Using a newly digitized database encompassing the universe of tariff lines across five US trade policy regimes between 1900 and 1940, we show that price dynamics combine with industry reliance on specific tariffs to generate large swings in average tariff levels. Intra-policy variation in...

How much has the US-China tariff war impacted economic outcomes in China? We address this question using high-frequency night lights data, together with measures of the trade exposure of fine grid locations constructed from Chinese firms' geo-coordinates. Exploiting within-grid variation over...

This paper examines the political economy of U.S. trade policy around the time of the Smoot-Hawley tariff of 1930, a period when policy was unconstrained by trade agreements. We consider a model of politically-optimal trade policy for a large country that can influence its terms of trade and...

We document the outbreak of a trade war after the U.S. adopted the Smoot-Hawley tariff in June 1930. U.S. trade partners initially protested the possible implementation of the sweeping tariff legislation, with many eventually choosing to retaliate by increasing their tariffs on imports from the...

We study how trade-policy dynamics affect the dynamics of trade volumes and the implications of these effects for estimates of the trade elasticity. We use data on US imports and trade policy from 1974-2017 for China and Vietnam--the countries with the largest import growth and the largest...

We study the role played by Chinese state-owned firms during the US-China trade war. Based on measures constructed from Chinese firm-level customs microdata, we show that the presence of state-owned enterprises (SOEs) in Chinese imports led to a large negative impact on US exports in addition to...

We evaluate the economic and environmental consequences of taxes on imported goods based on their carbon content. The analysis uses the simplest possible partial equilibrium framework, with one small open economy and a global pollution externality. It relies on graphs of supply and demand,...

What is the optimal monetary policy response to tariffs? This paper explores this question within an open-economy New Keynesian model and shows that the optimal monetary policy response is expansionary, with inflation rising above and beyond the direct effects of tariffs. This result holds...

We study the positive (not normative) effect of a permanent import tariff on trade deficits. We consider a two-period trade model with general preferences and technology. We first develop an aggregation result showing one can work with induced preferences over aggregate imports and exports. This...
