What is the optimal macroeconomic tariff when trade is imbalanced and the policy objectives go beyond social welfare and also include fiscal revenues, increasing the number of manufacturing jobs, and closing a trade deficit? We study these questions in an environment which allows for long-run...

This note addresses whether and when a trade war that imposes balanced trade (or even zero trade) can be consistent with initial non-zero net foreign asset positions. Using a bilateral trade model, we exploit insights from the classic literature on the Transfer Problem to characterize when gross...

Until the beginning of this century, the GATT/WTO system worked. Economic research provided a compelling explanation. It showed that if governments maximize the well-being of their own countries broadly defined, GATT/WTO principles would facilitate mutually beneficial cooperation over their...

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...

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 provide a general formula for optimal unilateral policies in multi-sector, general-equilibrium Ricardian models with various widely adopted labor market specifications. Sector-specific tariffs are summarized by a matrix of partial supply elasticities and the share of Home's import in foreign...

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...

Trade and industrial policies, while primarily intended to support domestic industries, may unintentionally stimulate technological progress abroad. We document this mechanism in the case of rare earth elements (REEs) - critical inputs for manufacturing at the knowledge frontier, with low...

We analyze a two-country model of trade in both legitimate and counterfeit products. Domestic firms own trademarks and establish reputations for delivering high-quality products in a steady-state equilibrium. Foreign suppliers export legitimate low-quality merchandise and counterfeits of...

The last two centuries witnessed the rise and fall of empires. We construct a model which rationalises this in terms of the changing trade gains from empires. In the model, empires are arrangements that reduce trade cost between an industrial metropole and the agricultural periphery. During...
