Conditional cash transfers (CCT) have recently received considerable attention as a potentially innovative and effective approach to the prevention of HIV/AIDS. We evaluate a conditional cash transfer program in rural Malawi which offered financial incentives to men and women to maintain their HIV status for approximately one year. The amounts of the reward ranged from zero to approximately 3-4 months wage. We find no effect of the offered incentives on HIV status or on reported sexual behavior. However, shortly after receiving the reward, men who received the cash transfer were 9 percentage points likely and women were 6.7 percentage points likely to engage in risky sex. Our analyses therefore question the "unconditional effectiveness" of CCT program for HIV prevention: CCT Programs that aim to motivate safe sexual behavior in Africa should take into account that money given in the present may have much stronger effects than rewards offered in the future, and any effect of these programs may be fairly sensitive to the specific design of the program, the local and/or cultural context, and the degree of agency an individual has with respect to sexual behaviors.
有条件现金转移支付(CCT)作为一种预防艾滋病毒/艾滋病的潜在创新有效方法,近来受到了广泛关注。我们对马拉维农村地区的一项有条件现金转移支付项目进行了评估,该项目为男性和女性提供经济激励,促使他们在大约一年时间内保持艾滋病毒检测阴性状态。奖励金额从零到大约三到四个月的工资不等。我们发现所提供的激励措施对艾滋病毒检测状态或报告的性行为没有影响。然而,在获得奖励后不久,领取现金转移支付的男性进行危险性行为的可能性增加了9个百分点,女性增加了6.7个百分点。因此,我们的分析对有条件现金转移支付项目预防艾滋病毒的“无条件有效性”提出了质疑:旨在激励非洲地区安全性行为的有条件现金转移支付项目应考虑到,当下给予的金钱可能比未来提供的奖励产生更强的效果,而且这些项目的任何效果可能对项目的具体设计、当地和/或文化背景以及个人在性行为方面的自主程度相当敏感。
