This paper assesses the effectiveness of an intervention aimed at improving the reading skills of struggling third-grade students in Colombia. In a series of randomized experiments, students participated in remedial tutorials conducted during school hours in small groups. Trained teachers used...

Evidence shows college increases earnings, but little causal evidence distinguishes whether these earnings come through human capital gains or from the signal a college degree sends. We use the unique situation created by the First World War, where several cohorts of West Point cadets were...

Internships during tertiary education have become substantially more common over the past decades in many industrialised countries. This study examines the impact of a voluntary intra-curricular internship experience during university studies on the probability of being invited to a job...
