We estimate peer effects for fourth graders in six European countries. The identification relies on variation across classes within schools. We argue that classes within primary schools are formed roughly randomly with respect to family background. Similar to previous studies, we find sizeable...

We examine the effects of malaria on educational attainment and income by exploiting geographic variation in malaria prevalence in India prior to a nationwide eradication program in the 1950s. We find that the program led to modest increases in income for prime age men. This finding is robust to...

One literature documents a significant, black-white gap in average test scores, while another finds a substantial narrowing of the gap during the 1980's, and stagnation in convergence after. We use two data sources -- the Long Term Trends NAEP and AFQT scores for the universe of applicants to...

We study a recent recruitment drive for public sector positions in Mexico. Different salaries were announced randomly across recruitment sites, and job offers were subsequently randomized. Screening relied on exams designed to measure applicants' intellectual ability, personality, and...

We examine how within-firm skill premia–wage differentials associated with jobs involving different skill requirements–vary both across firms and over time. Our firm-level results mirror patterns found in aggregate wage trends, except that we find them with regard to increases in firm size....

An emerging literature argues that changes in the allocation of workplace "tasks" between capital and labor, and between domestic and foreign workers, has altered the structure of labor demand in industrialized countries and fostered employment polarization--that is, rising employment in the...

We estimate the causal impact of school and classroom gender composition on achievement. We take advantage of the random assignment of Korean middle school students to single-sex schools, co-educational (coed) schools with single-sex classes, and coed schools with mixed-gender classes. Male...

This paper examines whether nutritional disruptions experienced during the stage of fetal development impair an individual’s labor market productivity later in life. We consider intrauterine exposure to the month of Ramadan as a natural experiment that might cause shocks to the inflow of...

This paper combines representative worker-level data that cover time-varying job-level task characteristics of an economy over a long time span with sector-level bilateral trade data for merchandize and services. We carefully create longitudinally consistent workplace characteristics from the...

We investigate the role of mechanical ability as another dimension that, jointly with cognitive and socio-emotional, affects schooling decisions and labor market outcomes. Using a Roy model with a factor structure and data from the NLSY79, we show that the labor market positively rewards...
