摘要

为遏制 Covid-19 大流行，各国采取了各种非药物干预措施（NPIs）。然而，个别措施能否成功减少感染人数仍存在争议。本文利用 181 个国家的面板数据集，估算了 12 种 NPI 对 2020 年疾病传播的影响。所采用的固定效应估计方法大大减少了对内生性的担忧。估计系数表明，尽管几乎所有措施都对病毒繁殖率有抑制作用，但学校停课和限制集会最为有效。戴口罩的义务在第二波中更为有效。需要大量资源的措施，如检测，在发达国家更为有效。(JEL 代码：C13、C23、D04 和 I18）

A Lockdown a Day Keeps the Doctor Away: The Global Effectiveness of Non-Pharmaceutical Interventions in Mitigating the Covid-19 Pandemic

Countries have employed a variety of non-pharmaceutical interventions (NPIs) in order to curtail the Covid-19 pandemic. However, the success of individual measures in reducing the number of infections remains controversial. This article exploits a panel dataset of 181 countries to estimate the effects of 12 NPIs on the spread of the disease in 2020. The employed fixed effects estimation greatly reduces endogeneity concerns. Estimated coefficients imply that while almost all measures had a dampening effect on the reproduction rate of the virus, school closings and restrictions on gatherings were most effective. The obligation to wear face masks was more effective during the second wave. Measures requiring significant resources, such as testing, were more effective in developed countries.
