12 Facts about Temporary Urbanists
Urban areas seem to be enjoying a renaissance of sorts due in part to the many young professionals who have moved into central neighborhoods since the 2000s. Many of these young professionals are thought to move back out after they have started families, but the details of these migration patterns are not well-known. I analyze data from the Federal Reserve Bank of New York/Equifax Consumer Credit Panel to answer 12 questions about these temporary urbanists?those who choose to move into an urban neighborhood and spend part of their early adulthood there.

The paper trail of knowledge transfers
Why do firms tend to locate near other firms? Economists suspect that geographic clustering spurs innovation by letting businesses tap a climate rich in informal transfers of knowledge. By tracing links between inventors filing for patents for the same inventions, Jeffrey Lin shares new evidence supporting the idea that proximity offers businesses tangible benefits.

Population, Migration, and Generations in Urban Neighborhoods
The number of people living in urban neighborhoods has been rising in recent decades. This Commentary investigates changes in the number, ages, and financial status of those who have been moving into and out of urban neighborhoods, using data from the Federal Reserve Bank of New York/Equifax Consumer Credit Panel. I find that since 2000, the increase in urban populations is the result of young adults migrating into urban neighborhoods and senior citizens aging in place. Urban populations have also become more educated and well to do. While declining urban neighborhoods may still outnumber ...

Inequality Across and Within US Cities around the Turn of the Twenty-First Century
We review key facts about inequality across and within US cities around the turn of the twenty-first century and discuss theoretical interpretations. Large cities are cities with a greater proportion of skilled workers. In those large and skill-intensive cities, wages are overall higher but are offset by higher rents. Those higher wages are particularly prevalent among high-skilled workers, so that the skill premium increases with city size and skill mix. Over the last few decades, these facts have become increasingly salient. We discuss possible explanations for these facts with the help of ...

Information and Communications Technology Spending and City Size
Firms in big cities are spending more on information and communications technology than firms in small cities, a likely cause of the growing economic divide between big and small U.S. cities.

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 ...

Cognitive Hubs and Spatial Redistribution
In the U.S., cognitive non-routine (CNR) occupations associated with higher wages are disproportionately represented in larger cities. To study the allocation of workers across cities, we propose and quantify a spatial equilibrium model with multiple industries that employ CNR and alternative (non-CNR) occupations. Productivity is city-industry-occupation specific and partly determined by externalities across local workers. We estimate that the productivity of CNR workers in a city depends significantly on both its share of CNR workers and total employment. Together with heterogeneous ...

How mortgage finance affects the urban landscape
This chapter considers the structure of mortgage finance in the U.S., and its role in shaping patterns of homeownership, the nature of the housing stock, and the organization of residential activity. We start by providing some background on the design features of mortgage contracts that distinguish them from other loans, and that have important implications for issues presented in the rest of the chapter. We then explain how mortgage finance interacts with public policy, particularly tax policy, to influence a household?s decision to own or rent, and how shifts in the demand for ...
