We revisit the identification argument of Kirkeboen et al. (2016) who showed how one may combine instruments for multiple unordered treatments with information about individuals' ranking of these treatments to achieve identification while allowing for both observed and unobserved heterogeneity...

We use the labor market for doctorates in the biomedical sciences, where career dislocation is common, as a case study of skill-task mismatch and its consequences. Using longitudinal, worker-level data on biomedical doctorates, we investigate mismatch as an explanation for the negative pecuniary...

Investment fund managers make asset allocation decisions on behalf of a significant segment of US households. To elucidate the incentives they operate under, as well as the income and career risks they face, we construct a unique and novel dataset, which encompasses detailed information on the...

Recent research concludes that wage returns to cognitive skills have declined in the U.S. We reassess this finding. Using decomposition methods, we document the pivotal role played by dynamic shifts in the distributions of pre-labor market cognitive skills. Our findings show these shifts explain...

This paper compares early childhood enrichment programs that promote social mobility for disadvantaged children within and across generations. Instead of conducting a standard meta-analysis, we present a harmonized primary data analysis of programs that shape current policy. Our analysis is a...

We document a robust negative relationship between mean annual hours in an occupation and the dispersion of annual hours within that occupation. We study a unified model of occupational choice and labor supply that features heterogeneity across occupations in the return to working additional...

The Global Repository of Income Dynamics (GRID) is a new open-access, cross- country database that contains a wide range of micro statistics on income inequality, dynamics, and mobility. It has four key characteristics: it is built on micro panel data drawn from administrative records; it fully...

For much of the 20th century, British students were tracked into higher-track (for the "top" 20%) or lower-track (for the rest) secondary schools. Opponents of tracking contend that the lower-track schools in these systems will inevitably provide low-quality education. In this paper I examine...
