I study how people understand and reason about trade and which factors shape their views on trade policy. I design and run large-scale surveys and experiments in the U.S. to elicit respondents' knowledge and understanding of trade. I also ask about their perceived economic gains and...

We exploit a natural experiment to study the extent to which popular attitudes toward trade are driven by economic fundamentals. In 2007, Costa Rica put a free trade agreement (FTA) to a national referendum. With a single question on the ballot, 59% of Costa Rican adult citizens cast a vote on...

This paper shows that ethnically remote locations do not reap the full peace dividend from increased market access. Exploiting the staggered implementation of the US-initiated Africa Growth and Opportunity Act (AGOA) and using high-resolution data on ethnic composition and violent conflict for...

Perceptions of global supply chains (GSCs) have shifted in recent years from a positive to a more cautious view. Standard GSC measures have mostly not adapted to this change as they focus on participation in, rather than exposure to, foreign supply chains. This paper presents the tools necessary...

We derive a small open economy (SOE) as the limit of an economy as the number or size of its trading partners goes to infinity and trade costs also go to infinity. We obtain this limit in the Armington, Eaton-Kortum, Krugman, and Melitz models. In all cases, the trade of the SOE with the foreign...

Import tariffs tend to be higher for final goods than for inputs, a phenomenon commonly referred to as tariff escalation. Yet neoclassical trade theory - and modern Ricardian trade models, in particular - predict that welfare-maximizing tariffs are uniform across sectors. We show that tariff...

We develop a dynamic extension of Dornbusch et al. (1977) with "rustiness": the home country has relatively higher unit costs tomorrow for goods it is not producing today. We solve for optimal tariff policy when there is a potential for a crisis: an increase in demand for goods produced abroad....

We use Chinese customs data to show that unofficial non-tariff barriers were responsible for 50\% of the overall reduction in Chinese imports from the U.S. during the height of the U.S.-China trade war in 2018 and 2019. We infer non-tariff barriers from the change in imports of U.S. products...

We review theoretical and empirical work on the economic effects of the United States and China trade relations during the last decades. We first discuss the origins of the China shock, its measurement, and present methods used to study its economic effects on different outcomes. We then focus...

We investigate the long-term effects of export opportunities to a large destination market on multinational affiliates and domestic firms in a low-income host country. The US-Vietnam Bilateral Trade Agreement reduced US import tariffs on exports from Vietnam. Tariff reductions led to entry of...
