Education, HIV, and Early Fertility: Experimental Evidence from Kenya
一项为期七年的随机评估发现，教育补贴能减少少女辍学、怀孕和结婚，但不减少性传播感染；政府的HIV课程（强调婚前禁欲）不减少怀孕或感染；两者结合比单独补贴更能减少感染，但减少辍学和怀孕的效果更差。
A seven-year randomized evaluation suggests education subsidies reduce adolescent girls' dropout, pregnancy, and marriage but not sexually transmitted infection (STI). The government's HIV curriculum, which stresses abstinence until marriage, does not reduce pregnancy or STI. Both programs combined reduce STI more, but cut dropout and pregnancy less, than education subsidies alone. These results are inconsistent with a model of schooling and sexual behavior in which both pregnancy and STI are determined by one factor (unprotected sex), but consistent with a two-factor model in which choices between committed and casual relationships also affect these outcomes.
