Tamaño de Familia y Orden de Nacimiento en Chile: Usando Gemelos como Experimento Natural

Claudia Sanhueza


This study estimates the causal effect of family size and birth order on educational attainment of individuals in the long run.

The results suggest that in Chile there is a negative relationship between family size and individuals’ educational achievements. Moreover, it shows a strong significant and positive effect of being a big brother. However, in larger families there is a nonlinear effect in which middle siblings are less favored.
