Empirical research on cities starts with a spatial equilibrium condition: workers and firms are assumed to be indifferent across space. This condition implies that research on cities is different from research on countries, and that work on places within countries needs to consider population,...

Compared to the federal government, the average citizen in the U.S. has far greater interaction with city governments, including policing, health services, zoning laws, utilities, schooling, and transportation. At the regional level, it is city governments that provide the infrastructure and...

We develop a new methodology for quantifying the tasks undertaken within occupations using over 3,000 verbs from more than 12,000 occupational descriptions in the Dictionary of Occupational Titles (DOTs). Using micro-data from the United States from 1880-2000, we find an increase in the...

A key reason for the existence of cities are the externalities created when people cluster together in close proximity. During Covid, such interactions came with health risks and people found other ways to interact. We document how cities changed during Covid and consider how the persistence of...

Why have white, less educated voters left the Democratic Party over the past few decades? Scholars have proposed ethnocentrism, social issues and deindustrialization as potential answers. We highlight the role played by the 1994 North American Free Trade Agreement (NAFTA). In event-study...

Governments go to great lengths to attract foreign multinationals because they are thought to raise the wages paid to their employees (direct effects) and to improve outcomes at local domestic firms (indirect effects). We construct the first U.S. employer-employee dataset with foreign ownership...

Does a location's growth benefit or suffer from being geographically close to large economic centers? Spatial proximity may lead to competition and hurt growth, but it may also improve market access and enhance growth. Using data on U.S. counties and metro areas for the period 1840-2017, we...

The development of the American economy was accompanied by significant spatial income inequalities between the northern and southern regions. While many factors contributed to northern industrialization and southern stagnation, an important factor was differences in their institutions. In the...

Most of the estimated effects are small and the signs are not wholly consistent with either model, under the null hypothesis that agriculture was the chief beneficiary of rail access. For example, we find that rail access appears to have increased urbanization, raised the likelihood of...

We review historical patterns of economic geography' for the United States from the colonial period to the present day. The analysis is framed in terms of two geographic scales: regions and cities. The compelling reason for studying geographic areas of different scales is that models that...
