This paper reviews recent research in spatial economics. The field of spatial economics is concerned with the determinants and effects of the location of economic activity in geographic space. It analyses how geographical location shapes the economic activities performed by agents, their...

This paper reviews recent quantitative urban models. These models are sufficiently rich to capture observed features of the data, such as many asymmetric locations and a rich geography of the transport network. Yet these models remain sufficiently tractable as to permit an analytical...

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...

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...

The recent development of quantitative urban models provides a new set of tools for evaluating transport improvements. Conventional cost-benefit analyses are typically undertaken in partial equilibrium. In contrast, quantitative urban models characterize the spatial distribution of economic...

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...

Modern metropolitan areas involve large concentrations of economic activity and the transport of millions of people each day between their residence and workplace. We use the revolution in transport technology from the invention of steam railways, newly-constructed spatially-disaggregated data...

We develop a model of human interaction to analyze the relationship between globalization and pandemics. Our framework provides joint microfoundations for the gravity equation for international trade and the Susceptible-Infected-Recovered (SIR) model of disease dynamics. We show that there are...

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...
