How do institutions and peer groups shape skills? We exploit a universal free-choice reform signaling less importance of advanced math-science in high school. We show how it amplified the fall in math-science skills and triggered gender convergence as boys crowded-in the free-choice reform. We...

We conduct a randomized controlled trial to study the effect of gender composition of teams on performance, self-concept, working style, and individual satisfaction in endogenously and exogenously formed teams. We randomly divide a sample of high school students into two groups: we assign...
