本文通过实验评估了尼日利亚农村妇女破伤风疫苗接种的心理成本与货币成本的相对重要性。我们比较了两种情况下的疫苗接种情况，以获得现金奖励：诊所出勤率与疫苗接种率。由于这两种情况之间的唯一区别是妇女是否需要在到达诊所时接种疫苗，因此这两组之间的诊所出勤率差异反映了接种疫苗的心理成本。与传统观点相反，我们没有发现任何重大的心理成本的证据。对疾病严重程度的了解会增加对疾病严重程度的感知，但不会增加疫苗接种。货币成本强烈影响疫苗接种决策。
This paper experimentally evaluates the relative importance of psychic costs of tetanus vaccination compared to monetary costs among women in rural Nigeria. We compare vaccine take-up between two conditions to receive cash incentives: clinic attendance vs. vaccine take-up. Because the only difference between these two conditions is whether a woman was required to receive a vaccine upon arrival at the clinic, the difference in clinic attendance between these two groups captures the psychic costs of vaccination. Contrary to conventional wisdom, we find no evidence for significant psychic costs. Priming about disease severity increases the perceived severity of disease, but not vaccine take-up. Monetary costs strongly affect vaccination decisions.
