The direct and spillover effects of a nationwide socio-emotional learning program for disruptive students

Social and emotional learning (SEL) programs teach disruptive students to improve their classroom behavior. Small-scale programs in high-income countries have been shown to improve treated students' behavior and academic outcomes. Using a randomized experiment, we show that a nationwide SEL program in Chile has no effect on eligible students. We find evidence that very disruptive students may hamper the program's effectiveness. ADHD, a disorder correlated with disruptiveness, is much more prevalent in Chile than in high-income countries, so very disruptive students may be more present in Chile than in the contexts where SEL programs have been shown to work.

Two-way fixed effects estimators with heterogeneous treatment effects

Linear regressions with period and group fixed effects are widely used to estimate treatment effects. We show that they estimate weighted sums of the average treatment effects (ATE) in each group and period, with weights that may be negative. Due to the negative weights, the linear regression coefficient may for instance be negative while all the ATEs are positive. We propose another estimator that solves this issue. In the two applications we revisit, it is significantly different from the linear regression estimator.
