This paper: i) estimates the effect that going to a better school has on students' academic achievement, and ii) explores whether this intervention induces behavioral responses on the part of children, their parents, and the school system. For the first task, we exploit almost 2,000 regression...

Economists have puzzled over why eligible individuals fail to enroll in social safety net programs. "Chilling effects" arising from an icy policy climate are a popular explanation for low program take-up rates among immigrants, but such effects are inherently hard to measure. This paper...
