This research measures the epidemiological and economic impact of COVID-19 spread in the US under different mitigation scenarios, comprising of non-pharmaceutical interventions. A detailed disease model of COVID-19 is combined with a model of the US economy to estimate the direct impact of labor supply shock to each sector arising from morbidity, mortality, and lockdown, as well as the indirect impact caused by the interdependencies between sectors. During a lockdown, estimates of jobs that are workable from home in each sector are used to modify the shock to labor supply. Results show trade-offs between economic losses, and lives saved and infections averted are non-linear in compliance to social distancing and the duration of the lockdown. Sectors that are worst hit are not the labor-intensive sectors such as the Agriculture sector and the Construction sector, but the ones with high valued jobs such as the Professional Services, even after the teleworkability of jobs is accounted for. Additionally, the findings show that a low compliance to interventions can be overcome by a longer shutdown period and vice versa to arrive at similar epidemiological impact but their net effect on economic loss depends on the interplay between the marginal gains from averting infections and deaths, versus the marginal loss from having healthy workers stay at home during the shutdown.
本研究通过不同缓解方案(包括非药物干预措施),测算 COVID-19 在美国的传播所带来的流行病学和经济影响。COVID-19 的详细疾病模型与美国经济模型相结合,以估算发病、死亡和封锁对各部门劳动力供应冲击的直接影响,以及各部门之间的相互依存关系造成的间接影响。在封锁期间,利用各部门中可远程办公的工作岗位估计数来调整劳动力供应冲击。研究结果表明,遵守社交距离和封锁持续时间的程度与经济损失、挽救生命和避免感染之间的权衡是非线性的。受打击最严重的部门不是劳动密集型部门,如农业部门和建筑部门,而是高价值工作部门,如专业服务部门,即使考虑到工作的远程办公能力也是如此。此外,研究结果表明,通过延长停工时间,可以克服对干预措施的低遵守程度,反之亦然,从而达到类似的流行病学影响,但它们对经济损失的净影响取决于避免感染和死亡的边际收益与停工期间让健康工人待在家里的边际损失之间的相互作用。
