Teacher training and HIV/AIDS prevention in West Africa: regression discontinuity design evidence from the Cameroon
利用断点回归设计评估喀麦隆教师培训项目对青少年生育、知识态度行为的影响，发现15-17岁女生生育率降低7-10个百分点，避孕套使用率显著提高。
We assess the impact on teenage childbearing as well as student knowledge, attitudes, and behavior of a typical HIV/AIDS teacher training program in the Cameroon. Applying a regression discontinuity design identification strategy based on the key administrative criterion that determined program deployment, we find that 15-17 year old girls in teacher training schools are between 7 and 10 percentage points less likely to have started childbearing, an objective proxy for the incidence of unprotected sex. They are also significantly more likely to have used a condom during their last sexual intercourse. For 12-13 year old girls, the likelihood of self-reported abstinence and condom use is also significantly higher in treated schools, while the likelihood of having multiple partners is significantly lower.
