Are daughters always the losers in the chore war? Evidence using household and twin data from Vietnam

This paper examines the gender gap in the division of housework in Vietnam among the household headsf children who are not married and still reside in the family home. We find that in a typical day, a daughter has a higher probability of undertaking some housework and for some 9.66 to 17.94 minutes longer than would an equivalent son. Among siblings in two-child families, a daughter who has a brother has the largest gender gap. However, once we control for differences in genetic endowment, with both twins involved in at least some housework, male-female twins spend approximately the same amount of time on housework. In a mutual decision-making scenario, among siblings in two-child families, an elder daughter would shoulder housework for the other sibling while the reverse holds for younger sisters, but only where the children are 20 years of age or younger. In addition, we find that besides sharing the family total housework load, one minute spent on housework by the mother inspires a 0.0481-0.298 minute increase in the time spent on housework by her daughter.
