居家令是否使人们留在家中?居家令对消费者行为的影响

Do Stay-at-Home Orders Cause People to Stay at Home? Effects of Stay-at-Home Orders on Consumer Behavior
Review of Economics and Statistics · 2021 · Diane Alexander、Ezra Karger

中文摘要

我们将COVID-19疫情期间居家令在县级层面的推行情况与匿名化手机记录及消费者支出数据相结合。我们记录了以下三种模式。第一,居家令使人们留在家中:在居家令生效后的两天内,县级人员流动指标下降了6%至7%。第二,居家令导致消费者在与人员流动相关的部门——小企业和大型连锁零售商——的支出大幅减少。第三,我们估计,全国范围内对居家令的反应相当一致;其效应不因县级收入、政治倾向或城乡属性而异。

Abstract

Abstract We link the county-level rollout of stay-at-home orders during the COVID-19 pandemic to anonymized cell phone records and consumer spending data. We document three patterns. First, stay-at-home orders caused people to stay home: county-level measures of mobility declined 6% to 7% within two days of when the stay-at-home order went into effect. Second, stay-at-home orders caused large reductions in spending in sectors associated with mobility: small businesses and large retail chains. Third, we estimate fairly uniform responses to stay-at-home orders across the country; effects do not vary by county-level income, political leanings, or urban/rural status.
