The Deferred Acceptance algorithm (DA) frequently produces Pareto inefficient allocations in school choice problems. While a number of efficient mechanisms that Pareto-dominate DA are available, a normative question remains unexplored: which students should benefit from efficiency enhancements?...

The Deferred Acceptance (DA) mechanism can generate inefficient placements. Although Pareto-dominant mechanisms exist, it remains unclear which and how many students could improve their DA assignment. We characterize the set of unimprovable students and show that it includes those unassigned or...

This paper investigates the historical origins of female genital cutting (FGC). We test the historical hypothesis that FGC is associated with the Red Sea route of the African slave trade, where women were typically sold as concubines in the Middle East and infibulation was used as a means to...

Adolescents' educational choices are shaped by their peers. Using administrative data covering the entire population of Italian middle school students, we show that exposure to high-achieving male peers in math reduces the likelihood that girls choose a scientific high school track. To...

Standard economic theory assumes that consumers ignore the externalities they create, such as emissions from burning fossil fuels and generating waste. In an incentivized study (N = 3, 718), we find that most people forgo substantial gains to avoid imposing negative externalities on others....
