A new study in the American Economic Journal: Applied Economics assessed life trajectories of children in Lesotho, Africa, across a wide range of educational and later-life outcomes. The study found that children who enrolled in primary school at an older age—despite an initial disadvantage in years of schooling—were more likely to remain in school through adolescence, obtained higher total years of schooling, and developed greater literacy than children who began primary school at younger ages. The older children were also more likely to delay marriage, have fewer children, hold higher-earning jobs, and accumulate greater wealth.
