Relationship among COVID-19, mobility, and food service vouchers in Japan.

In 2020, the Japanese government launched the Go To Eat campaign, a policy initiative involving the distribution of vouchers to households for use at restaurants, with the aim of supporting the food service industry, which had experienced a significant decrease in sales due to the government’s ‘self-restraint request’ during the COVID-19 pandemic. This paper uses a nonparametric method to investigate the relationship between the Go To Eat campaign and the spread of COVID-19 in Japan by examining food service expenditures, mobility, positive polymerase chain reaction (PCR) tests, and the Indices of Industrial Production. The distribution of food service expenditures changed in October and November, when the campaign started, as well as in December, when the campaign ended. In addition, the distribution of mobility changed in January 2021, when a state of emergency was declared. The Go To Eat campaign was economically effective as a temporary subsidy, and it might have facilitated mobility in a way that was difficult to control for some time. As such, the indirect effect of the campaign on the rise in the number of positive PCR tests is undeniable. [ABSTRACT FROM AUTHOR]
