What Matters (and What Does Not) in Households' Decision to Invest in Malaria Prevention

This paper tests the effects on the take-up of a preventative health product of two interventions based on behavioral models derived from psychology: varying the framing of the perceived benefits; and having people verbally commit to purchase the product. I find that none of these interventions had a significant effect (whether economically or statistically) on take-up, and that the gender of the household member targeted was also irrelevant. In contrast, I find that take-up is sensitive to price, as in Cohen and Dupas (2008), and is correlated with indicators of household’s wealth.

本文基于心理学衍生的行为模型，针对两项干预措施对某预防性健康产品采纳率的影响展开研究：其一为调整感知收益的表述框架，其二为引导研究对象口头承诺购买该产品。研究结果表明，上述两项干预措施均未对产品采纳率产生显著影响，且无论从经济层面还是统计层面均无明显作用；同时，目标家庭成员的性别同样无关联影响。与之形成鲜明对比的是，产品采纳率对价格存在敏感性，这与Cohen与Dupas（2008）的研究结论一致，且与家庭财富相关指标存在相关性。
