This paper shows a somehow counterintuitive result: an increase in the exam difficulty may reduce the average quality (productivity) of selected individuals. Since the exam does not verify all skills, when its standard rises, candidates with relatively low skills emphasized in the test and high...

Evidence about job mobility outside the U.S. is scarce and difficult to compare cross-nationally because of non-uniform data. We document job mobility patterns of college graduates in their first three years in the labor market, using unique uniform data covering 11 European countries and Japan....

How much of the income-based gaps in cognitive ability and academic achievement could be closed by a two-year, center-based early childhood education intervention? Data from the Infant Health and Development Program (IHDP), which randomly assigned treatment to low birth weight children from both...

This paper derives original series of average years of schooling in the United States 1870-1930, which take into account the impact of mass migrations on the US educational level. We reconstruct the foreign-born US population by age and by country of origin, while combining data on the flow of...

Concerns about the breadth of the U.S. income distribution and limited intergenerational mobility have led to a focus on educational achievement gaps by socio-economic status (SES). Using intertemporally linked assessments from NAEP, TIMSS, and PISA, we trace the achievement of U.S. student...

Since 1950, U.S. educational attainment has increased substantially. While the median student in 1950 dropped out of high school, the median student today attends some college. In an environment with ability heterogeneity and positive sorting between ability and school tenure, the expansion of...

We study the returns to experience in teaching, estimated using supervisor ratings from classroom observations. We describe the assumptions required to interpret changes in observation ratings over time as the causal effect of experience on performance. We compare two difference-in-differences...

We provide new evidence that cash transfers following the birth of a first child can have large and long-lasting effects on that child's outcomes. We take advantage of the January 1 birthdate cutoff for U.S. child-related tax benefits, which results in families of otherwise similar children...
