Recent research by Joshua Angrist and Alan Krueger has used information on exact dates of birth in the 1960 to 1980 federal censuses to study the impact of compulsory schooling laws on school attendance. This paper modifies their methodology to analyze similar data in the 1900 federal census to...

Between 1940 and 1950 wage differentials within and between labor market groups narrowed significantly - the so-called 'Great Compression'. This paper disaggregates the Great Compression into its public and private components. Wage compression in the public sector, along with a decline in the...

We revisit a famous controversy in labor economics: the debate between W.S. Woytinsky and Clarence Long over "added" and "discouraged" worker effects in the late 1930s. According to Woytinsky, the Depression created large numbers of added workers, persons who entered the labor force when the...

Between 1950 and 1970 the labor force participation rate of southern black males aged 16-19 declined by 27 percentage points. This decline has been attributed to two demand-side shocks: the mechanization of cotton agriculture in the 1950s and extensions in the coverage of the federal minimum...

During the nineteenth century the United States urbanized - the share of the population living in urban areas increased - and industrialized - the share of the labor force in manufacturing increased. Our survey of the literature and analyses of census data suggests that a key reason was the...

The structure of wages narrowed considerably during the 1940's, increased slightly during the 1950's and 1960's, and then expanded greatly after 1970. The era of wage stretching of the past two decades has been a current focus, but we return attention here to the decade that was witness to an...

Two opposing views of the antebellum economy are tested. One is that aggregate economic activity was severely diminished and that unemployment was substantial and prolonged during several downturns. The alternative interpretation is that antebellum fluctuations were more apparent than real;...

This paper presents an analysis of birth weights and infant mortality in mid-nineteenth century Philadelphia using obstetrics records of Philadelphia's Almshouse hospital, an institution for the poor and their offspring. Children of the poor weighed between 2,900 and 3,200 grams on average at...

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...
