日本政府已采取多项措施，包括宣布进入紧急状态，以对抗COVID-19的蔓延。我们研究了政府政策导致人们行为变化的机制。我们使用智能手机位置数据构建了一个每日都道府县级的居家措施，以确定以下两种效果：（1）公民根据政府的要求避免外出的效果，以及（2）政府公告加强了对疫情严重性的认识，人们自愿避免外出的效果。我们的主要发现如下。首先，紧急状态的宣布使通过第一个渠道离开家园的人数减少了8.5%，这与美国封锁所获得的估计数量级相同。其次，一个都道府县的新增感染人数每增加1%，该都道府县的人们外出次数就会减少0.027%。第三，政府的要求要为东京都内外出人数减少的约四分之一负责，其余四分之三则是市民通过政府公告和每日发布感染人数等方式获得新信息的结果。研究结果表明，遏制COVID-19传播的重要因素不是强有力的、具有法律约束力的措施，而是提供适当的信息，鼓励人们改变自己的行为。
Japan’s government has taken a number of measures, including declaring a state of emergency, to combat the spread COVID-19. We examine the mechanisms through which the government’s policies have led to changes in people’s behavior. Using smartphone location data, we construct a daily prefecture-level stay-at-home measure to identify the following two effects: (1) the effect that citizens refrained from going out in line with the government’s request, and (2) the effect that government announcements reinforced awareness with regard to the seriousness of the pandemic and people voluntarily refrained from going out. Our main findings are as follows. First, the declaration of the state of emergency reduced the number of people leaving their homes by 8.5% through the first channel, which is of the same order of magnitude as the estimates obtained for lockdowns in the United States. Second, a 1% increase in new infections in a prefecture reduces people’s outings in that prefecture by 0.027%. Third, the government’s requests are responsible for about one quarter of the decrease in outings in Tokyo, while the remaining three quarters are the result of citizens obtaining new information through government announcements and the daily release of the number of infections. The findings suggest that what mattered for containing the spread of COVID-19 was not strong, legally binding measures but the provision of appropriate information that encouraged people to change their behavior.
