To prevent exponential spread of COVID-19, many governments restricted economic activity through lockdowns. We model these restrictions as shocks to productivity by sector and trace total equilibrium effects across the economy using techniques from production network economics. We combine this economic model with an epidemiological model of income shocks to long-term health. On both long-run health and economic grounds, it is better to keep upstream sectors such as transportation, manufacturing, and wholesale open than consumer-facing sectors such as retail and restaurants.
为防止新冠病毒肺炎(COVID-19)呈指数级传播,许多政府通过封锁措施限制了经济活动。我们将这些限制措施模拟为各部门生产率受到的冲击,并运用生产网络经济学的技术来追踪经济中的总体均衡效应。我们将这一经济模型与收入冲击对长期健康影响的流行病学模型相结合。从长期健康和经济两方面来看,保持运输、制造和批发等上游部门开放,比保持零售和餐饮等面向消费者的部门开放更好。
