Using a large administrative data set from Chile, we find that, on average, boys perform better than girls in mathematics. In this paper, we document several features of their relative performance. First, we note that the gender gap appears to increase with age (it doubles between fourth grade...

We establish the presence of a gender gap in mathematics across many low- and middle-income countries using detailed, comparable test score data. Examining micro level data on school performance linked to household demographics we note that first, the gender gap appears to increase with age....

Our identification strategy relies on the random assignment of students to teaching classes. We find...

This paper studies the effect of improved neonatal health care on mortality and long run academic achievement in school. We use the idea that medical treatments often follow rules of thumb for assigning care to patients, such as the classification of Very Low Birth Weight (VLBW), which assigns...
