U.S. educational and occupational wage differentials were exceptionally high at the dawn of the twentieth century and then decreased in several stages over the next eight decades. But starting in the early 1980s the labor market premium to skill rose sharply and by 2005 the college wage premium...

Economic inequality is higher today than it has been since 1939, as measured by both the wage structure and wealth inequality. But the comparison between 1939 and 1999 is largely made out of necessity; the 1940 U.S. population census was the first to inquire of wage and salary income and...

We present the first estimates of the returns to years of schooling before 1940 using a large sample of men and women, employed in a variety of sectors and occupations, from the Iowa State Census of 1915. We find that the returns to a year of high school, and to a year of college, were...

Current concern with relationships among particular technologies, capital, and the wage structure motivates this study of the origins of technology-skill complementarity in manufacturing. We offer evidence of the existence of technology-skill and capital-skill (relative) complementarities from...

Between 1890 and the late 1920s the premium to high school education declined substantially for both men and women. In 1890 ordinary office workers, whose positions generally required a high school diploma, earned almost twice what production workers did. But by the late 1920s they earned about...

Private for-profit institutions have been the fastest growing part of the U.S. higher education sector. For-profit enrollment increased from 0.2 percent to 9.1 percent of total enrollment in degree-granting schools from 1970 to 2009, and for-profit institutions account for the majority of...

The race between education and technology provides a canonical framework that does an excellent job of explaining U.S. wage structure changes across the twentieth century. The framework involves secular increases in the demand for more-educated workers from skill-biased technological change,...

Pharmacy has become a female-majority profession that is highly remunerated with a small gender earnings gap and low earnings dispersion relative to other occupations. We sketch a labor market framework based on the theory of equalizing differences to integrate and interpret our empirical...

Occupations are segregated by sex today, but were far more segregated in the early to mid-twentieth century when married women began to enter the labor force in large numbers. It is difficult to rationalize sex segregation and 'wage discrimination' on the basis of men's taste for distance from...

Single women in the U.S. dominated the female labor force from 1870 to 1920. Data on the home life and working conditions of women in 1888 and 1907 enable the estimation of earnings functions. Work in the manufacturing sector for these women was task oriented and payment was frequently by the...
