Sister competition and birth order effects among marriage-aged girls: Evidence from a field experiment in rural Bangladesh

Abstract

Early marriage before the age of 18 is prevalent among adolescent girls in Bangladesh, but the timing of marriage is not uniform across daughters within a household, with some sisters marrying earlier than others. Using survey data from a novel field experiment from rural Bangladesh, I find that girls ages 10-21 with lower birth order tend to be married at a younger age, even when controlling for confounding nature of household size on birth order. Additionally, girls with younger sisters are more likely to be married and at a younger age than girls with younger brothers. The findings on dowry are inclusive.
