Birth weight and child gender are controlled for in each regression.

^aEndogenous variable. The instrumental variables include two types of interaction terms. The first type includes the interaction terms between the within-twin difference in birth weight and the household and parental level variables, and the second type includes the interaction terms between the within-twin difference in gender and the level variables. The household and parental level variables include a rural indicator, maternal working sector, age, ethnicity, and schooling years
