This paper examines the causal effects of computer-aided instruction (CAI) on children's cognitive and noncognitive skills. We ran a clustered randomized controlled trial at five elementary schools with more than 1,600 students near Phnom Penh, Cambodia. After 3 months of intervention, we find...

We estimate month-of-birth effects on cognitive and noncognitive skills, as well as factors relevant to skill formation. Our estimates indicate that younger students in a given grade cohort have lower cognitive and noncognitive skills. To shed light on the underlying mechanisms, we also examine...

We estimate the effects of class-size reduction by exploiting exogenous variation caused by Maimonides' rule, which requires that the maximum class size is 40 students and that classes be split into two when 41 students are enrolled. Our data cover all fourth to ninth graders in 1,064 public...
