Although social distancing can effectively contain the spread of infectious diseases by reducing social interactions, it may have economic effects. Crises such as the COVID-19 pandemic create dilemmas for policymakers because the long-term implementation of restrictive social distancing policies may cause massive economic damage and ultimately harm healthcare systems. This paper proposes an epidemic control framework that policymakers can use as a data-driven decision support tool for setting efficient social distancing targets. The framework addresses three aspects of the COVID-19 pandemic that are related to social distancing or community mobility data: modeling, financial implications, and policy-making. Thus, we explore the COVID-19 pandemic and concurrent economic situation as functions of historical pandemic data and mobility control. This approach allows us to formulate an efficient social distancing policy as a stochastic feedback control problem that minimizes the aggregated risks of disease transmission and economic volatility. We further demonstrate the use of a deep learning algorithm to solve this control problem. Finally, by applying our framework to U.S. data, we empirically examine the efficiency of the U.S. social distancing policy.
虽然社交距离可以通过减少社交互动有效遏制传染病传播,但可能会产生经济影响。诸如新冠疫情这样的危机给政策制定者带来了两难困境,因为长期实施限制性社交距离政策可能会造成巨大经济损害,并最终损害医疗系统。本文提出了一个疫情防控框架,政策制定者可将其用作数据驱动的决策支持工具,以设定有效的社交距离目标。该框架涉及新冠疫情与社交距离或社区流动性数据相关的三个方面:建模、财务影响和政策制定。因此,我们将新冠疫情和同期经济形势作为历史疫情数据和流动性控制的函数进行探究。这种方法使我们能够将有效的社交距离政策制定为一个随机反馈控制问题,以最小化疾病传播和经济波动的综合风险。我们进一步展示了使用深度学习算法来解决这一控制问题。最后,通过将我们的框架应用于美国数据,我们实证检验了美国社交距离政策的效率。
