Face Masks and GDP
- Increased face mask usage is projected to substitute for lockdowns to prevent significant economic damage if virus numbers deteriorate further in Sunbelt states.
- Estimates indicate a national mandate would raise face mask adherence from approximately 70% to 85%.
- This projected increase in wearing rates is expected to reduce the daily growth rate of infections from roughly 1.6% to 0.6%.
- A reduction in growth rate is anticipated to occur within a couple of weeks of implementing a face mask mandate.
- The economic impact of a necessary lockdown is estimated at approximately 5% of GDP, suggesting a mandate would avoid this loss.
- The benefits of a national mandate would likely be concentrated in regions lacking statewide mandates, particularly in the South where infection increases are largest.
- Analyses consistently find that face masks reduce virus spread, despite some contradictory results regarding different approaches in international data.
- An increase in statewide mandates could ultimately achieve a similar impact to a national mandate.
- A national mandate is viewed as a more straightforward and potentially quicker mechanism for achieving increased adherence compared to piecemeal state-level actions.
