In finding a career, workers tend to make numerous job changes, with the majority of 'complex' changes (i.e. those involving changes of industry) occurring relatively early in their working lives. This pattern suggests that workers tend to experiment with different types of work before settling...

Empirically, large employers have been shown to devote greater resources to filling vacancies than small employers. Following this evidence, this paper offers a theory of producer size based on labor market search, whereby a key factor in the determination of producer's total employment is the...

Human capital-based theories of cities suggest that large, economically diverse urban agglomerations increase worker productivity by increasing the rate at which individuals acquire skills. One largely unexplored implication of this theory is that workers in big cities should see faster growth...

Through their influence on the cross-sectional distribution of productivity across firms and workers, job creation and destruction likely have an impact on the rate at which aggregate productivity changes over time. However, the nature of this effect is not, a priori, clear. While a broad...

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...

Existing research has found an inverse relationship between urban density and the degree of income inequality within metropolitan areas, suggesting that, as cities spread out, they become increasingly segregated by income. This paper examines this hypothesis using data covering more than 160000...

The surge in U.S. wage inequality over the past several decades is now commonly attributed to an increase in the returns paid to skill. Although theories differ with respect to why, specifically, this increase has come about, many agree that it is strongly tied to the increase in the relative...

Human capital tends to have significant external effects within local markets, increasing the average income of individuals within the same metropolitan area. However, evidence on both human capital spillovers and peer effects in neighborhoods suggests that these effects may be confined to...

This paper offers a descriptive empirical analysis of the geographic pattern of income inequality within a sample of 359 US metropolitan areas between 1980 and 2000. Specifically, we decompose the variance of metropolitan area-level household income into two parts: one associated with the degree...

One of the most robust findings emerging from studies of industrial agglomeration is the rise in productivity that tends to accompany it. What most studies have not addressed, however, is the potential role played by human capital externalities in driving this relationship. This paper seeks to...
