We use data from a unique survey of members of drug-trafficking gangs in favelas (slums) of Rio de Janeiro, Brazil, to characterize drug-trafficking jobs and study the selection into gangs, analyzing what distinguishes gang-members from other youth living in favelas. We also estimate wage...

Previous research has not always found that boys and girls are treated differently in rural India. However estimates of the effect of gender on parental investments could be biased if girls end up in larger families due to son-biased stopping rules. Using a novel identification strategy that...

Recent advances in behavioral decision research, behavioral economics, and life-span development psychology provide leverage for expanding our understanding of the decision to retire earlier versus later. This report examines how cognitive abilities, perceptions about the future, and other...

Although the self-selection of emigrants is determined by di¤erences in the returns to education, according to the celebrated Roy model, empirical evidence suggests that migrants tend to be favorably selected. This paper argues that financial con- straints might be useful to explain this...

There is considerable debate in the literature as to whether boys and girls are treated differently in India. But son-biased stopping rules imply that previous estimates are likely to be biased. The authors propose a novel identification strategy to properly identify the effects of child gender...

Although previous research has not always found that boys and girls are treated differently in rural India, son-biased stopping rules imply that estimates of the effect of gender on parental investments are likely to be biased because girls systematically end up in larger families. We propose a...

The Roy model predicts that migrants will be disproportionately drawn from the lower half of the educational distribution of the sending country if the sending country has a higher return to schooling. However, Mexican immigrants in the U.S. tend to be disproportionately drawn from the middle of...

This paper estimates the time preference of poor households in rural Mexico. It uses data from a program that randomly assigned communities to treatment and control and paid transfers to poor households in treatment communities. The randomization implies that differences in consumption between...
