Urban decentralization and income inequality: is sprawl associated with rising income segregation across neighborhoods?
Existing research shows an inverse relationship between urban density and the degree of income inequality within metropolitan areas; this information suggests that as urban areas spread out, they become increasingly segregated by income. This paper examines this hypothesis using data covering more than 165,000 block groups within 359 U.S. metropolitan areas for the years 1980, 1990, and 2000. The findings indicate that income inequality-defined by the variance of the log household income distribution-does indeed rise significantly as urban density declines. This increase, however, is ...

Human capital growth in a cross section of U.S. metropolitan areas
Growth of human capital, defined as the change in the fraction of a metropolitan area's labor force with a bachelor's degree, is typically viewed as generating a number of desirable outcomes, including economic growth. Yet, in spite of its importance, few empirical studies have explored why some economies accumulate more human capital than others. This paper attempts to do so using a sample of more than 200 metropolitan areas in the United States over the years 1980, 1990, and 2000. The results reveal two consistently significant correlates of human capital growth: population and the existing ...

Changing trends in the labor force: a survey
The composition of the American workforce has changed dramatically over the past half century as a result of both the emergence of married women as a substantial component of the labor force and an increase in the number of minority workers. The aging of the population has contributed to this change as well. In this paper, the authors review the evidence of changing labor force participation rates, estimate the trends in labor force participation over the past 50 years, and find that aggregate participation has stabilized after a period of persistent increases. Moreover, they examine the ...

Evidence on wage inequality, worker education, and technology
The rise in U.S. wage inequality over the past two decades is commonly associated with an increase in the use of "skill-biased" technologies (e.g., computer equipment) in the workplace, yet relatively few studies have attempted to measure the direct link between the two. This paper explores the relationship among inequality, worker education levels, and workplace computer usage using a sample of 230 U.S. industries between 1983 and 2002. The results generate two primary conclusions: First, this rising inequality in the United States has been caused predominantly by increasing wage ...

Neighborhoods that don't work
Unemployment is becoming more concentrated. Neighborhoods that had high unemployment in 1980 had even higher unemployment 20 years later. What are the possible reasons-and solutions-for this trend?

Human capital externalities and adult mortality in the U.S.
Human capital is now widely recognized to confer numerous benefits, including higher incomes, lower incidence of unemployment, and better health, to those who invest in it. Yet, recent evidence suggests that it also produces larger, social (external) benefits, such as greater aggregate income and productivity as well as lower rates of crime and political corruption. This paper considers whether human capital also delivers external benefits via reduced mortality. That is, after conditioning on various individual-specific characteristics including income and education, do we observe lower rates ...

Urban crime and labor mobility
We present a model of crime where two municipalities exist within a metro area (MSA). Consistent with the literature, local law enforcement has a crime reduction effect and a crime diversion effect. The former confers a spillover benefit to the other municipality, while the latter a spillover cost. If the net spillovers are positive (negative), then the respective Nash enforcement levels are too low (high) from the perspective of the MSA. When we allow for Tiebout type mobility, labor will move to the location offering lower disutility crime (including the tax burden). To attract labor both ...

Industry localization and earnings inequality: evidence from U.S. manufacturing
While the productivity gains associated with the geographic concentration of industry (i.e. localization) are by now well-documented, little work has considered how those gains are distributed across individual workers. This paper offers evidence on the connection between total employment and the relative wage earnings of high- and low-skill workers (i.e. inequality) within two-digit manufacturing industries across the states and a collection of metropolitan areas in the U.S. between 1970 and 1990. Using two different measures - 90-10 percentile gaps in both overall and residual wages - I ...

Productivity and the geographic concentration of industry: the role of plant scale
A large body of research has established a positive connection between an industry's productivity and the magnitude of its presence within locally defined geographic areas. This paper examines the extent to which this relationship can be explained by a micro-level underpinning commonly associated with productivity: establishment scale. Looking at data on two-digit manufacturing across a sample of U.S. metropolitan areas, I find two primary results. First, average plant size - defined in terms of numbers of workers - increases substantially as an industry's employment in a metropolitan area ...
