This paper shows how to remove attenuation bias in regression analyses due to measurement error in historical data for a given variable of interest by using a secondary measure which can be easily generated from digitized newspapers. We provide three methods for using this secondary variable to...

Housing is the most important asset for the vast majority of American households and a key driver of racial disparities in wealth. This paper studies how residential segregation by race eroded black wealth in prewar urban areas. Using a novel sample of matched addresses from prewar American...

Recent work has argued that zoning is responsible for racial segregation, disparities in public goods provision, growing regional inequality, and exploding housing costs in productive areas. However, the slow-moving nature of land regulation's effects suggests a crucial need for historical...

Segregation has been a recurring social concern throughout human history. While much progress has been made to our understanding of the mechanisms driving segregation, work to date has ignored the role played by location-specific amenities. Nonetheless, policy remedies for reducing group...

Comprehensive zoning is ubiquitous in U.S. cities, yet we know surprisingly little about its long-run impacts. We provide the first attempt to measure the causal effect of land use regulation over the long term, using as our setting Chicago's first (1923) comprehensive zoning ordinance. Our...

Residential segregation by race grew sharply during the early twentieth century as black migrants from the South arrived in northern cities. The existing literature emphasizes collective action by whites to restrict where blacks could live as the driving force behind this rapid rise in...

Zoning has been cited as a discriminatory policy tool by critics, who argue that ordinances are used to deter the entry of minority residents into majority neighborhoods through density restrictions (exclusionary zoning) and locate manufacturing activity in minority neighborhoods (environmental...

Like today, one hundred years ago air pollution was a matter of grave concern in the world's most polluted cities. In the wake of its famous 1908-9 social survey, the City of Pittsburgh commissioned an "Economic Survey of Pittsburgh" from John T. Holdsworth, a prominent institutional economist...
