Are Daughters Always the Losers in the Chore War? Evidence Using Household Data from Vietnam
研究了越南18岁以下兄弟姐妹间的家务性别差距，发现女儿每天比儿子多做5.25分钟无偿家务，但14岁以下差距很小，15岁后差距缩小，表明父母开始考虑女儿教育。
We examine the gender gap in housework in Vietnam among siblings aged less than 18 years. We show daughters undertake 5.25 minutes more unpaid housework per day than sons. However, the gender gap in housework is negligible for children aged less than 14 years. A decline in the gender gap at 15 years of age suggests parents eventually begin to consider the education of their daughters. Before then, however, the gender gap increases with age and can be even greater if daughters also engage in paid work.
