This paper reviews recent research on geography and trade. One of the key empirical findings over the last decade has been the role of geography in shaping the distributional consequences of trade. One of the major theoretical advances has been the development of quantitative spatial models that...

This paper reviews the recent theoretical literature on heterogeneous firms and trade, which emphasizes firm selection into international markets and reallocations of resources across firms. We discuss the empirical challenges that motivated this research and its relationship to traditional...

The second half of the twentieth century saw large-scale suburbanization in the United States, with the median share of residents who work in the same county where they live falling from 87 to 71 percent between 1970 and 2000. We introduce a new methodology for discriminating between the three...

We develop a quantitative spatial model that incorporates a rich geography of trade and imperfect labor mobility between locations. We provide general results for the existence, uniqueness and comparative statics of the equilibrium. We show how the model can be used to undertake counterfactuals...

Economic activity is highly unevenly distributed within cities, as reflected in the concentration of economic functions in specific locations, such as finance in the Square Mile in London. The extent to which this concentration reflects natural advantages versus agglomeration forces is central...

Two central insights from the Schumpeterian approach to innovation and growth are that the pace of innovation is endogenously determined by the expectation of future profits and that growth is inherently a process of creative destruction. As international trade is a key determinant of firm...

We develop a dynamic spatial general equilibrium model with forward-looking investment and migration decisions. We characterize analytically the transition path of the spatial distribution of economic activity in response to shocks. We apply our framework to the reallocation of US economic...

Using data from 2018, a number of studies have found that recent U.S tariffs have been passed on entirely to U.S. importers and consumers. These results are surprising given that trade theory has long stressed that tariffs applied by a large country should drive down foreign prices. Using...

One of the most successful empirical relationships in international trade is the gravity equation, which relates bilateral trade flows between an origin and destination to bilateral trade frictions, origin characteristics, and destination characteristics. A key decision for researchers in...

This paper explores the impacts of the Trump administration's trade policy on prices and welfare. Over the course of 2018, the U.S. experienced substantial increases in the prices of intermediates and final goods, dramatic changes to its supply-chain network, reductions in availability of...
