Urban and Regional Migration Estimates: Will Your City Recover from the Pandemic?
The COVID-19 pandemic caused a massive change in the movement of people at both the neighborhood and the regional levels in the United States. New migration estimates will enable us to track which urban neighborhoods and metro areas are returning to their old migration patterns and where the pandemic has permanently shifted migration trends.

Rethinking Detroit
We study the urban structure of the city of Detroit. Following several decades of decline, the city's current urban structure is clearly not optimal for its size, with a business district immediately surrounded by a ring of largely vacant neighborhoods. We propose a model with residential externalities that features multiple equilibria at the neighborhood level. In particular, developing a residential area requires the coordination of developers and residents, without which it may remain vacant even if its fundamentals are sound. We embed this mechanism in a quantitative spatial economics ...

Subprime mortgages, foreclosures, and urban neighborhoods
This paper analyzes the impact of the subprime mortgage crisis on urban neighborhoods in Massachusetts. We explore the topic using a data set that matches race and income information from Home Mortgage Disclosure Act data with property-level, transaction data from Massachusetts Registry of Deeds offices. With these data, we show that much of the subprime lending in the state was concentrated in urban neighborhoods and that minority homeownerships created with subprime mortgages have proved exceptionally unstable in the face of rapid price declines. The evidence in Massachusetts suggests that ...

Terrorism and the resilience of cities
The September 11 attacks in New York and Washington have forced Americans to confront the fact that to live or work in a large city is to be at greater risk of large-scale terrorism. What do these risks, and the public perception of them, imply for cities in general and the future of New York City in particular? In this article, the authors begin their exploration of this issue by examining why cities exist in the first place. To conduct their analysis, they simulate two key theoretical models of economic geography, using data that approximate the characteristics of a major U.S. city as well ...

How should suburbs help their central cities?
In this paper, we study the question whether suburbs should help finance the core public services of their central cities. We review three arguments that have been offered in favor of suburbs' fiscal assistance to their central cities. First, the central city provides public services that benefit suburban residents. Second, the central city may provide redistributive services to low-income central city residents that benefit suburbanites with redistributive preferences for such transfers. For efficiency, suburbanites should contribute toward such services in proportion to the benefits they ...

Urban colossus: why is New York America's largest city?
This article was presented at a conference organized by the Federal Reserve Bank of New York in April 2005, "Urban Dynamics in New York City." The goal of the conference was threefold: to examine the historical transformations of the engine-of-growth industries in New York and distill the main determinants of the city's historical dominance as well as the challenges to its continued success; to study the nature and evolution of immigration flows into New York; and to analyze recent trends in a range of socioeconomic outcomes, both for the general population and recent immigrants more ...

Polycentric urban structure: the case of Milwaukee
The author finds that Milwaukee has one employment subcenter, located at the western edge of the city. The subcenter has significant but highly localized effects on both employment and population densities in the Milwaukee area.

Matching and learning in cities: urban density and the rate of invention
This paper examines the role local labor markets play in the production of innovations. The authors appeal to a labor market matching model ( la Berliant, Reed, and Wang 2004) to argue that in dense urban areas, workers are more selective in their matches and are therefore more productive. They find that, all else equal, patent intensity (patents per capita) is 20 percent higher in a metropolitan area with an employment density (jobs per square mile) twice that of another metropolitan area. Since local employment density doubles nearly four times across their sample, the implied gains in ...
