The fear and hatred of others who are different has economic consequences because such feelings are likely to translate into discrimination in labor, credit, housing, and other markets. The implications range from earnings inequality to intergenerational mobility. Using German data from various...

We propose an approximation method for analyzing Ericson and Pakes (1995)-style dynamic models of imperfect competition. We develop a simple algorithm for computing an ``oblivious equilibrium,'' in which each firm is assumed to make decisions based only on its own state and knowledge of the long...

Many dynamic problems in economics are characterized by large state spaces which make both computing and estimating the model infeasible. We introduce a method for approximating the value function of high-dimensional dynamic models based on sieves and establish results for the: (a) consistency,...

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...

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...

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...

This paper uses confidential Census data, specifically the 1990 and 2000 Census Long Form data, to study the demographic processes underlying the gentrification of low-income urban neighborhoods during the 1990's. In contrast to previous studies, the analysis is conducted at the more refined...

We test for evidence of spatial, residence-based labor market networks. Turnover is lower for workers more connected to their neighbors generally and more connected to neighbors of the same race or ethnic group. Both results are consistent with networks producing better job matches, while the...

Over the last 10 years, a variety of analysts have blamed high unemployment and stagnant economic growth in Europe on inflexible labor markets and pointed to the US as a more flexible economy, due to its less regulated labor markets and less generous social protection programs. This paper...

Much has been said about the stylized fact that the economically successful are not only wealthier but also healthier than the less affluent. There is little doubt about the existence of this socio-economic gradient in health, but there remains a vivid debate about its source. In this paper, we...
