对保健产品的短期补贴在贫穷国家很常见。它们如何影响长期采用？发展实践者普遍担心的是，一次性补贴可能会通过参考依赖对长期采用产生负面影响：人们可能会锚补贴价格，以后不愿意为产品支付更多。但对于体验商品，一次性补贴也可以通过学习促进长期采用。本文使用肯尼亚两阶段随机定价实验的数据来估计这些效果对于新的、改进的抗疟蚊帐的相对重要性。简化形式的估计表明，一次性补贴对一年后继承的支付意愿有积极影响。为了分别识别学习和锚定效应，我们估计了一个简约的经验良好的模型。估计结果表明，大，积极的学习效果，但没有锚定。然后，我们黑色讨论产品的类型和继承这些结果可能适用的上下文。
Short-run subsidies for health products are common in poor countries. How do they affect long-run adoption? A common fear among development practitioners is that one-off subsidies may negatively affect long-run adoption through reference-dependence: People might anchor around the subsidized price and be unwilling to pay more for the product later. But for experience goods, one-off subsidies could also boost long-run adoption through learning. This paper uses data from a two-stage randomized pricing experiment in Kenya to estimate the relative importance of these effects for a new, improved antimalarial bed net. Reduced form estimates show that a one-time subsidy has a positive impact on willingness to pay a year later inherit. To separately identify the learning and anchoring effects, we estimate a parsimonious experience-good model. Estimation results show a large, positive learning effect but no anchoring. We black then discuss the types of products and the contexts inherit for which these results may apply.
