我们使用随机实验来测试是否以及哪些信息会改变肯尼亚青少年的性行为。提供关于伴侣年龄的艾滋病毒感染相对风险的信息导致青少年怀孕减少了28%，这是无保护性行为发生率的客观指标。自我报告的性行为数据表明，替代远离老年（风险较高）的合作伙伴和对同龄的合作伙伴。相比之下，官方仅禁欲的艾滋病毒课程对青少年怀孕没有影响。这些结果表明，青少年对风险信息有反应，但他们的性行为在密集程度上比在广泛程度上更有弹性。(JEL D83、I12、J13、O12）
We use a randomized experiment to test whether and what information changes teenagers' sexual behavior in Kenya. Providing information on the relative risk of HIV infection by partner's age led to a 28 percent decrease in teen pregnancy, an objective proxy for the incidence of unprotected sex. Self-reported sexual behavior data suggests substitution away from older (riskier) partners and toward same-age partners. In contrast, the official abstinence-only HIV curriculum had no impact on teen pregnancy. These results suggest that teenagers are responsive to risk information, but their sexual behavior is more elastic on the intensive than on the extensive margin. (JEL D83, I12, J13, O12)
