The Differential Impact of Reopening States With and Without COVID-19 Face Mask Mandates on County-Level Consumer...

By the end of 2020, 38 states and the District of Columbia had issued requirements that people wear face masks when in public settings to counter SARS-CoV-2 transmission. To examine the role face mask mandates played in economic recovery, we analyzed the interactive effect of having a state face mask mandate in place on county-level consumer spending after state reopening, adjusting for county rates of new COVID-19 cases and deaths, time trends, and county-specific effects.

We collected county-specific data from state executive orders, consumer spending data from the Opportunity Insights Economic Tracker, and COVID-19 case and death data from the Centers for Disease Control and Prevention COVID-19 tracker. Using an event study approach, we compared county-level changes in consumer spending before and after state-issued closure orders were lifted and assessed the interactive effect of state-issued face mask mandates.

The lifting of state-issued closures was associated with an average increase in consumer spending across all counties studied within 1 month. However, the increase was 1.2-1.7 percentage points higher in counties with a state face mask mandate in place than in counties without a state face mask mandate.

In addition to their public health benefits, face mask mandates may have assisted economic recovery during the COVID-19 pandemic, suggesting they are a strong public health strategy for policy makers to consider now and for potential future pandemics arising from airborne viruses.
