I examine the epidemiological and economic effects of two types of lockdowns during the COVID-19 pandemic in Japan: a voluntary lockdown by which people voluntarily stayed at home in response to the risk of infection, and a request-based lockdown by which the government requested people to stay at home without legal enforcements I use empirical evidence on these two types of lockdowns to extend an epidemiological and economic model: the SIR-Macro model I calibrate this extended model to Japanese data and conduct some numerical experiments The results show that the interaction of these two types of lockdowns plays an important role in the low proportion of infectious individuals and the large decrease in consumption in Japan
