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....

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...

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...

We estimate the impact of trade policy uncertainty (TPU) on CES import price indices, focusing on the implications of Britain's exit from the European Union (Brexit). Our analysis reveals that an increase in the probability of Brexit increases U.K. import price indices by raising the prices of...

We use the 2018-2019 U.S. trade war to examine how supply chains adjustments to a tariff cost shock affect imports and exports. Using confidential firm-trade linked data, we show that the decline in imports of tariffed goods was driven by discontinuations of U.S. buyer-foreign supplier...

We estimate a model of firm export dynamics featuring cross-country complementarities. The firm decides where to export by solving a dynamic combinatorial discrete choice problem, for which we develop a solution algorithm that overcomes the computational challenges inherent to the large...

We study optimal dynamic trade policies in an Eaton-Kortum model with technology diffusion through trade. The process of innovation and diffusion is one in which new ideas are combined with insights from others. Trade thus affects technology by determining the distribution from which producers...

We show that reducing the probability of a trade war promotes long-term importer-exporter relationships that ensure provision of high-quality inputs via incentive premia. Empirically, we introduce a method for distinguishing between these Japanese versus spot-market (i.e., American)...

We use the dynamics of U.S. imports across goods in the period around the U.S.-China trade war with a model of exporter dynamics to estimate the dynamic path of the probability of transiting between Normal Trade Relations and a trade war state. We find (i) there was no increase in the likelihood...

This paper uses millions of records from a cross-country and time series database of both publicly listed and private companies to disentangle the role of technological change, market power, and globalization in driving a fall in the labor share. Labor shares are measured at the enterprise level...
