Abstract

We study the effects of combining financial incentives with nudges to promote antibody testing and vaccination to prevent the spread of rubella. In 2019, the Japanese government began providing vouchers for free antibody testing and vaccination to men aged 40–57 years. Vouchers were automatically mailed to 40–46-year-old men in 2019. Those aged 47–57 would receive vouchers after April 2020, while they could obtain vouchers for undertaking antibody testing and being vaccinated in 2019 by applying. Focusing on this policy distinction, we conducted an online field experiment with Japanese 40–57-year-old men in February and March 2020. We randomly provided six nudge-based reminder messages recommending antibody testing and vaccination and tracked self-reported behavior until March of 2020. One nudge-based reminder with an altruistic message on fetal harm through infection from men to pregnant women significantly promoted antibody testing among the 40–46-year-old men who had already received vouchers as a financial incentive. This message could also encourage their vaccinations. In contrast, any nudge-based reminder had no promoting effect for the 47–57-year-old men who must apply for vouchers.

在促进抗体检测和疫苗接种的经济激励措施中添加基于劝告的提醒措施，以预防风疹的传播

我们研究了将经济激励与诱导相结合，促进抗体检测和疫苗接种以预防风疹传播的效果。2019 年，日本政府开始向 40-57 岁的男性提供免费抗体检测和疫苗接种券。代金券在 2019 年自动邮寄给 40-46 岁的男性。47-57 岁的人将在 2020 年 4 月后收到代金券，而他们可以在 2019 年通过申请获得进行抗体检测和接种的代金券。针对这一政策区别，我们在 2020 年 2 月和 3 月对 40-57 岁的日本男性进行了在线实地实验。我们随机提供了六条基于劝告的提醒信息，建议进行抗体检测和疫苗接种，并跟踪自我报告行为，直至 2020 年 3 月。其中一条基于劝导的提醒信息带有利他主义色彩，告诉人们男性传染给孕妇会对胎儿造成危害，这极大地促进了已获得代金券作为经济激励的 40-46 岁男性进行抗体检测。这一信息还可以鼓励他们接种疫苗。相比之下，对于必须申请代金券的 47-57 岁男性来说，任何基于暗示的提醒都没有促进作用。

期刊介绍： The Journal of Behavioral and Experimental Economics (formerly the Journal of Socio-Economics) welcomes submissions that deal with various economic topics but also involve issues that are related to other social sciences, especially psychology, or use experimental methods of inquiry. Thus, contributions in behavioral economics, experimental economics, economic psychology, and judgment and decision making are especially welcome. The journal is open to different research methodologies, as long as they are relevant to the topic and employed rigorously. Possible methodologies include, for example, experiments, surveys, empirical work, theoretical models, meta-analyses, case studies, and simulation-based analyses. Literature reviews that integrate findings from many studies are also welcome, but they should synthesize the literature in a useful manner and provide substantial contribution beyond what the reader could get by simply reading the abstracts of the cited papers. In empirical work, it is important that the results are not only statistically significant but also economically significant. A high contribution-to-length ratio is expected from published articles and therefore papers should not be unnecessarily long, and short articles are welcome. Articles should be written in a manner that is intelligible to our generalist readership. Book reviews are generally solicited but occasionally unsolicited reviews will also be published.
