Gender Differences in Children's Nutrition and Access to Health Care in Pakistan
分析了巴基斯坦0-5岁儿童在营养和医疗保健获取上的性别差异，发现男孩在医疗保健上更受优待，但女孩营养状况不差甚至更好，表明家庭内性别歧视主要源于投资回报差异而非偏好男孩。
This article analyses gender differences in children's nutrition and access to health care in Pakistan with a view to uncovering parents motives for the favouring of sons in South Asia. It is found that, among 0 to 5-year-old children, boys are favoured in the allocation of health care. However, girls appear as nourished as or better nourished than boys. This is taken to be evidence that intra-household gender discrimination has primary origins not in parental preference for boys but in differential returns to parents from investment in boys and girls.
