Immigrant enclaves offer valuable ethnic amenities but may delay assimilation. We study enclave formation in the Age of Mass Migration by using the centralized location decisions for "ethnic" Catholic churches. After a church opening, same-ethnicity residents of chosen neighborhoods experienced...

Since the 1970s, computerized machine tools have been replacing semi-skilled manufacturing workers, contributing to factory automation. We build a novel measure of exposure to computer numerical control (CNC) based on initial variation in tool types across industries and differential shifts...

This chapter examines the causes and consequences of black-white residential segregation in the United States. Segregation can arise through black self-segregation, collective action to exclude blacks from white neighborhoods, or individual mobility of white households. Historically, whites used...

I examine changes in the city-suburban housing price gap in metropolitan areas with and without court-ordered desegregation plans over the 1970s, narrowing my comparison to housing units on opposite sides of district boundaries. The desegregation of public schools in central cities reduced the...

Four million blacks left the South from 1940 to 1970, doubling the northern black workforce. I exploit variation in migrant flows within skill groups over time to estimate the elasticity of substitution by race. I then use this estimate to calculate counterfactual rates of wage growth. I find...

Residential segregation by jurisdiction generates disparities in public services and education. The distinctive American pattern - in which blacks live in cities and whites in suburbs - was enhanced by a large black migration from the rural South. I show that whites responded to this black...

Affluent towns often deliver high-quality public services to their residents. I estimate the willingness to pay to live in a high-income suburb, above and beyond the demand of wealthy neighbors, by measuring changes in housing prices across city-suburban borders as the income disparity between...

We document wide and persistent variation in women's representation and success across graduate programs in economics. Using new data on early career outcomes for recent graduates, including first job placement, publications and promotion, we compare (anonymized) departments on outcomes for...

The nullification of slave wealth after the U.S. Civil War (1861-65) was one of the largest episodes of wealth compressions in history. We document that white Southern households holding more slave assets in 1860 lost substantially more wealth by 1870, relative to households that had been...

The recent digitization of complete count census data is an extraordinary opportunity for social scientists to create large longitudinal datasets by linking individuals from one census to another or from other sources to the census. We evaluate different automated methods for record linkage,...
