Score contribution per author:
α: calibrated so average coauthorship-adjusted count equals average raw count
In African countries, children often combine school and work. This article exploits Senegalese panel data to assess the relationship between child labor and learning, measured by test scores. Test scores from the beginning of primary school control for children's cognitive abilities, and children's past time allocation decisions are instrumented by changes in rainfall and distance to primary school. Some of the tests were administered verbally in order to pick up effects for children who had only attended school very briefly. I do not find that children's past participation in economic activities is associated with lower adolescent cognitive achievement, but rather that it is associated with higher oral mathematics scores. This association is stronger when I control for years of schooling, which suggests that work does displace schooling but does allow children to acquire some skills.
