The supply and demand of skilled workers in cities and the role of industry composition
The share of high-skilled workers in U.S. cities is positively correlated with city size, and this correlation strengthened between 1980 and 2010. Furthermore, during the same time period, the U.S. economy experienced a significant structural transformation with regard to industrial composition, most notably in the decline of manufacturing and the rise of high-skilled service industries. To decompose and investigate these trends, this paper develops and estimates a spatial equilibrium model with heterogeneous firms and workers that allows for both industry-specific and skill-specific ...

The Push of Big City Prices and the Pull of Small Town Amenities
As house prices continue to rise in large, supply-constrained cities, what are the implications for other places that have room to grow? Recent literature suggests that amenities that improve quality of life are becoming increasingly important in location decisions. In this paper, we explore how location amenities have differentially driven population and price dynamics in small towns versus big cities, with a focus on the role of housing supply. We provide theory and evidence that demand for high-amenity locations has increased in recent decades. High-amenity counties in large metropolitan ...

Freeway Revolts!
Freeway revolts were widespread protests across the U.S. following early urban Interstate construction in the mid-1950s. We present theory and evidence from panel data on neighborhoods and travel behavior to show that diminished quality of life from freeway disamenities inspired the revolts, a?ected the allocation of freeways within cities, and changed city structure. First, actual freeway construction diverged from initial plans in the wake of the growing freeway revolts and subsequent policy responses, especially in central neighborhoods. Second, freeways caused slower growth in population, ...

Congestion, Agglomeration, and the Structure of Cities
Supersede WP 13-25. Congestion costs in urban areas are significant and clearly represent a negative externality. Nonetheless, economists also recognize the production advantages of urban density in the form of positive agglomeration externalities. The long-run equilibrium outcomes in economies with multiple correlated but o setting externalities have yet to be fully explored in the literature. Therefore, I develop a spatial equilibrium model of urban structure that includes both congestion costs and agglomeration externalities. I then estimate the structural parameters of the model using a ...

Making Sense of Urban Patterns
Why do cities everywhere exhibit the same general patterns of density and development? And how can we explain some striking variations? The streets of Philadelphia roll west through a collage of urban environments familiar to city dwellers nearly everywhere. From Penn Square, the central site of the iconic stone City Hall, Market Street traverses a canyon of concrete and glass office buildings that gradually give way to commercial and apartment structures and mixed uses. A mile from City Hall, the busy thoroughfare crosses the Schuylkill River, and density again picks up as the University of ...

Location dynamics: a key consideration for urban policy
What determines where businesses and households locate? Location decisions can affect the economic health of cities and metropolitan areas. But as Jeffrey Brinkman explains, how firms, residents, and workers go about choosing where to locate can involve complex interactions with sometimes unpredictable consequences.

The Costs and Benefits of Fixing Downtown Freeways
Urban freeways spurred our suburban boom. Can burying them do the same for the urban core?

The Geography of Travel Behavior in the Early Phase of the COVID-19 Pandemic
We use a panel of county-level location data derived from cellular devices in the U.S. to track travel behavior and its relationship with COVID-19 cases in the early stages of the outbreak. We find that travel activity dropped significantly as case counts rose locally. People traveled less overall, and they specifically avoided areas with relatively larger outbreaks, independent of government restrictions on mobility. The drop in activity limited exposure to out-of-county virus cases, which we show was important because such case exposure generated new cases inside a county. This suggests the ...

Big cities and the highly educated: what's the connection
Why are more college-educated workers gravitating to large metropolitan areas? As Jeffrey Brinkman explains, amenities are increasingly important in people?s location decisions, a trend that may help inform urban policymaking.

Not in My Backyard? Not So Fast. The Effect of Marijuana Legalization on Neighborhood Crime
This paper studies the effects of marijuana legalization on neighborhood crime using unique geospatial data from Denver, Colorado. We construct a highly local panel data set that includes changes in the location of marijuana dispensaries and changes in neighborhood crime. To account for endogenous retail dispensary locations, we use a novel identification strategy that exploits exogenous changes in demand across different locations. The change in geographic demand arises from the increased importance of access to external markets caused by a change in state and local policy. The results imply ...
