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...

Many economists believe knowledge production generates positive spillovers among knowledge producers. The available evidence, however, is mixed. We argue that spillovers can exist along three dimensions (idea, geographic, and collaboration space). To isolate the key channel through which...

We compare two approaches to analyzing the effects of immigration on the labor market and find that the estimated effect of immigration on U.S. native labor outcomes depends critically on the empirical experiment used. Area analyses contrast the level or change in immigration by area with the...

This paper examines the link between interindustry wage differentials and subsequent growth of industry variables such as employment, GDP and labor productivity. We find that industries that paid higher than average wages in 1959 experienced significantly lower employment growth and GDP growth...
