A nudge changes people's actions without removing their options or altering their incentives. During the COVID-19 vaccine rollout, the Swedish Region of Uppsala sent letters with pre-booked appointments to inhabitants aged 16-17 instead of opening up manual appointment booking. Using regional and municipal vaccination data, we document a higher vaccine uptake among 16- to 17-year-olds in Uppsala compared to untreated control regions (constructed using the synthetic control method as well as neighboring municipalities). The results highlight pre-booked appointments as a strategy for increasing vaccination rates in populations with low perceived risk.
推动（nudge）改变了人们的行为，而没有移除他们的选项或改变他们的激励。在 COVID-19 疫苗推出期间，瑞典乌普萨拉地区向 16-17 岁的居民发送了带有预预约的信件，而不是开放手动预约。使用区域和市政疫苗接种数据，我们记录了乌普萨拉地区 16 至 17 岁人群的疫苗接种率高于未处理的对照地区（使用合成控制方法以及邻近的市政当局构建）。结果突出了预预约作为提高低风险人群疫苗接种率的策略。
