COVID-19, stigma, and habituation: evidence from mobility data.

Background: The Japanese government has restricted people's going-out behavior by declaring a non-punitive state of emergency several times under COVID-19. This study aims to analyze how multiple policy interventions that impose non-legally binding restrictions on behavior associate with people's going-out.

Theory: This study models the stigma model of self-restraint behavior under the pandemic with habituation effects.

COVID-19 with Stigma: Theory and Evidence from Mobility Data.

This study conducts both theoretical and empirical analyses of how non-legally-binding COVID-19 policies affect people's going-out behavior. The theoretical analysis assumes that under a declared state of emergency, the individual going out suffers psychological costs arising from both the risk of infection and the stigma of going out. Our hypothesis states that under a declared state of emergency people refrain from going out because it entails a strong psychological cost.
