Do Sanitary Pads Improve Girls' Educational Outcomes?
研究印度喀拉拉邦学校安装卫生巾自动售货机对女童教育的影响，发现免费提供卫生巾使七年级女生辍学率下降24个百分点，出勤率上升23个百分点，对落后种姓、农村和公立学校女生效果更显著。
Abstract Using a staggered installation of sanitary pad vending machines across schools in the Indian state of Kerala, we study the impacts of free monthly access to sanitary pads on girls' educational outcomes. We find that the number of dropouts among female students in the 7th-grade decrease by 24 percentage points and the attendance rate increases by 23 percentage points after the treatment. Our results are mainly driven by girls in backward-caste, rural schools, and public schools, supporting the idea that free distribution of sanitary pads alleviates cost of obtaining sanitary pads.
