We demonstrate a striking but previously unnoticed relationship between city size and the black-white wage gap, with the gap increasing by 2.5% for every million-person increase in urban population. We then look within cities and document that wages of blacks rise less with agglomeration in the...

This paper documents the presence of non-economic career motivations in the U.S. labor market, explores reasons why such motivations could arise, and provides an explanation for why they might have persisted across many generations. The analysis links ethnic (migrant) labor market networks in...

We analyze the secular decline in interstate migration in the United States between 1991 and 2011. Gross flows of people across states are about 10 times larger than net flows, yet have declined by around 50 percent over the past 20 years. We argue that the fall in migration is due to a decline...

This paper presents a new, dynamic economic model of criminal activity. Individuals are endowed with legal and criminal human capital. Potential incomes in legal and criminal sectors depend on the level of the relevant human capital, the rate of return, and random shocks. Both types of human...

The persistence of U.S. unemployment has risen with each of the last three recessions, raising the specter that future U.S. recessions might look more like the Eurosclerosis experience of the 1980s than traditional V-shaped recoveries of the past. In this paper, we revisit possible explanations...

The onset of World War I spurred the "Great Migration" of African Americans from the U.S. South, arguably the most important internal migration in U.S. history. We create a new panel dataset of more than 5,000 men matched from the 1910 to 1930 census manuscripts to address three interconnected...

We show that isolated capital cities are robustly associated with greater levels of corruption across US states, in line with the view that this isolation reduces accountability, and in contrast with the alternative hypothesis that it might forestall political capture. We then provide direct...

This paper investigates the effect of local immigration enforcement regimes on the migration decisions of the foreign born. Specifically, the analysis uses individual level American Community Survey data to examine the effect of recent 287(g) agreements which allow state and local law...

In this chapter we analyze immigration and its effect on urban and regional economies focusing on productivity and labor markets. While immigration policies are typically national, the effects of international migrants are often more easily identified on local economies. The reason is that their...
