This paper examines the effect of waterborne lead exposure on infant mortality in American cities over the period 1900 to 1920. Variation across cities in water acidity and the types of service pipes, which together determined the extent of lead exposure, identifies the effects of lead on infant...

Using historical census and survey data, Long and Ferrie (2013) found a significant decline in social mobility in the United States from 1880 to 1973. We present two critiques of the Long-Ferrie study. First, the data quality of the Long-Ferrie study is more limiting than the authors...

The US tolerates more inequality than Europe and believes its economic mobility is greater than Europe?s, though they had roughly equal rates of intergenerational occupational mobility in the late twentieth century. We extend this comparison into the nineteenth century using 10,000...

Causal estimates of the benefits of increased schooling using U.S. state schooling laws as instruments typically rely on specifications which assume common trends across states in the factors affecting different birth cohorts. Differential changes across states during this period, such as...

We reanalyze Long and Ferrie's data. We find that the association of occupational status across generations was quite similar over time and place. Two significant differences were: (i) American farms in 1880 were far more open to men who had nonfarm backgrounds than were American farms in 1973...

We provide new estimates of migrant flows into and out of America during the Age of Mass Migration at the turn of the twentieth century. Our analysis is based on a novel data set of administrative records covering the universe of 24 million migrants who entered Ellis Island, New York between...

We present new evidence on the long-run trend of occupational task content by race in the United States, 1900-2021. Black workers began the transition to better paid, cognitive-intensive modern jobs at least a generation after white workers; substantial convergence only occurred from 1960...

The failure of the Freedman's Savings Bank (FSB), one of the only Black-serving banks in the early post-bellum South, was an economic catastrophe and one of the great episodes of racial exploitation in post-Emancipation history. It was also most Black Americans' first experience of banking. Can...

The consensus view among economic historians is that wage inequality in American manufacturing followed an inverted-U path from the early nineteenth century until just before World War Two. The previous literature, however, has been unable to fully document this path over time, or fully assess...

Income and wealth inequality rose over the first 150 years of US history. They rose in Britain before 1875, especially 1740–1810. The first half of the 20th century equalized pre-fisc incomes both in Britain and in America. From the 1970s to the 1990s inequality rose in both countries,...
