There is currently a heated debate about making face masks compulsory in public spaces to contain COVID-19. A key concern is that such policies could lead to risk compensating behaviour and thereby undermine efforts to maintain social distancing and reduce mobility. We provide first evidence on the impact of compulsory face mask policies on community mobility. We exploit the staggered implementation of policies by German states and measure community mobility using geolocated smartphone data. We find no evidence suggesting that compulsory masking policies affect community mobility in Germany. We can rule out even small increases larger than 0.03 standard deviations.
There is currently a heated debate about whether to introduce policies requiring the general public to wear protective face masks to contain COVID-19. A key concern is that compulsory face mask policies will make the public feel safer (due to risk compensation), and may consequently undermine the most important public-health advice to contain COVID-19 – which is to reduce mobility and maintain social distancing. This study provides first evidence on the impact of compulsory face mask policies on community mobility. We use a difference-in-differences design, which exploits the staggered implementation of compulsory face mask policies by German states. We use anonymised GPS data from Google's Location History feature to measure daily mobility in public spaces (groceries and pharmacies, transport hubs and workplaces). We find no evidence that compulsory face mask policies affect community mobility in public spaces in Germany. The evidence provided in this paper makes a crucial contribution to ongoing debates about how to best manage the COVID-19 pandemic.
There is an ongoing debate about making face masks compulsory in public spaces to contain COVID‐19. A key concern is that such policies could undermine efforts to maintain social distancing and reduce mobility. We provide first evidence on the impact of compulsory face mask policies on community mobility. We exploit the staggered implementation of policies by German states during the first wave of the pandemic and measure mobility using geo‐located smartphone data. We find that compulsory masking policies led to a short‐term reduction in community mobility, with no significant medium‐term effects. We can rule out even small increases in mobility.This article is protected by copyright. All rights reserved.
