This paper studies the role of the family in determining the skill composition and labor market experiences of immigrants in the United States. Our theoretical framework, based on the assumption that family migration decisions maximize household income, shows that the family attenuates the...

Within the conceptual framework of the Roy model, this paper provides an empirical analysis of internal migration flows using data from the National Longitudinal Surveys of Youth. The theoretical approach highlights regional differences in the returns to skills: regions that pay higher returns...

We study one aspect of the link between welfare and unwed motherhood: the relationship between benefit levels and the time-to-first-marriage and time-to-next-birth among women whose first" child was born out of wedlock. We use twin births to generate effectively random variation in welfare...

Knowledge generation is key to economic growth, and scientific prizes are designed to encourage it. But how does winning a prestigious prize affect future output? We compare the productivity of Fields medalists (winners of the top mathematics prize) to that of similarly brilliant contenders. The...

The largest and most important flow of scientific talent in the world is the migration of international students to the doctoral programs offered by universities in industrialized countries. This paper uses the opening of China in 1978 to estimate the causal effect of this flow on the...

This paper investigates whether the parameters of labor demand functions are sensitive to alternative methods of estimation. The assumption that the production technology is of the Generalized Leontief type implies that the demand system can be estimated by analyzing cross-section differences in...

This paper presents an empirical analysis of immigrant participation in the welfare system using the 1970 and 1980 U.S. Censuses. The availability of two cross-sections allows for identification of cohort and assimilation effects. The data indicate that recent immigrant cohorts use the welfare...

Self-employment is an important aspect of the immigrant experience in the labor market. Self-employment rates for immigrants exceed 15 percent for some national groups. This paper addresses three related questions on the self-employment experience of immigrants. First, how do self-employment...

It has been difficult to open up the black box of knowledge production. We use unique international data on the publications, citations, and affiliations of mathematicians to examine the impact of a large post-1992 influx of Soviet mathematicians on the productivity of their American...

The wage impact of immigration depends crucially on the elasticity of substitution between similarly skilled immigrants and natives and the elasticity of substitution between high school dropouts and graduates. This paper revisits the estimation of these elasticities. The U.S. data indicate that...
