This paper is concerned with the production of PhDs in the United States and Canada in the post-WW II period, overall and by gender and major discipline. The effects of the explanatory variables lagged six years are consistent with the model. Military conscription with educational exemptions and...

We offer an integrated explanation and empirical analysis of the polarization of U.S. employment and wages between 1980 and 2005, and the concurrent growth of low skill service occupations. We attribute polarization to the interaction between consumer preferences, which favor variety over...

Compared to other immigrants to the United States, recent Jewish immigrants from the former Soviet Union have achieved high levels of English language proficiency and earnings. They experience disadvantages in both dimensions at arrival, but because of steeper improvements with duration in the...

We analyze the effect of rising Chinese import competition between 1990 and 2007 on U.S. local labor markets, exploiting cross-market variation in import exposure stemming from initial differences in industry specialization and instrumenting for U.S. imports using changes in Chinese imports by...

This paper is concerned with the English language requirements (both level and importance) of occupations in the United States, as measured by the O*NET database. These scores are linked to microdata on employed adult (aged 25 to 64) males, both native born and foreign born, as reported in the...

Manufacturing accounts for more than three-quarters of U.S. corporate patents. The competitive shock to this sector emanating from China's economic ascent could in theory either augment or stifle U.S. innovation. Using three decades of U.S. patents matched to corporate owners, we quantify how...

After a decade in which wages and employment fell precipitously in low-skill occupations and expanded in high-skill occupations, the shape of U.S. earnings and job growth sharply polarized in the 1990s. Employment shares and relative earnings rose in both low and high-skill jobs, leading to a...

The Public Use Microdata Sample (PUMS) from the 1860 Census of Population (one percent sample of free people) is used to study the occupational distribution and the determinants of socio-economic status of Jewish men (age 16 to 60) compared to other free men. Jews cannot be identified directly,...

This paper explores the geographic overlap of trade and technology shocks across local labor markets in the United States. Regional exposure to technological change, as measured by specialization in routine task-intensive production and clerical occupations, is largely uncorrelated with regional...

Rates of labor force participation in the US in the second half of the nineteenth century among free women were exceedingly (and implausibly) low, about 11 percent. This is due, in part, to social perceptions of working women, cultural and societal expectations of female's role, and lack of...
