Do Stay-at-Home Orders Cause People to Stay at Home? Effects of Stay-at-Home Orders on Consumer Behavior
利用手机定位和消费数据，研究发现居家令实施两天内居民出行减少6%-7%，并导致小企业和大型零售商的消费大幅下降，且效果在全国各地较为一致。
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.
