An anonymous reader quotes a report from The Washington Post: After a late-spring lull, daily coronavirus cases in the United States have again hit record highs, driven by resurgent outbreaks in states such as Florida, Arizona and California. Hospitals in Houston are already on the brink of being overwhelmed, and public health experts worry the pandemic’s body count will soon again be climbing in tandem with the daily case load. The dire situation has raised the specter of another round of state-level stay-at-home orders to halt the pandemic’s spread and caused a number of governors to pause or reverse their ongoing reopening plans. Against this backdrop, a team of economists at investment bank Goldman Sachs has published an analysis suggesting more painful shutdowns could be averted if the United States implements a nationwide mask mandate.
“A face mask mandate could potentially substitute for lockdowns that would otherwise subtract nearly 5% from GDP,” the team, led by the company’s chief economist, Jan Hatzius, writes. It’s worth noting the authors of the report are economists and not public health experts. Their primary motivation is to protect the economic interests of Goldman Sachs’s investors, which is why they’re interested in the effects of federal policy on gross domestic product. But their findings are in line with a number of other published studies on the efficacy of masks. The Goldman Sachs report notes the United States is a global outlier with respect to face mask use, which is widespread in Asia and currently mandated in many European countries. Though the Centers for Disease Control and Prevention “recommends” the use of masks in public and 20 states plus the District of Columbia have implemented their own mandates, there is no binding national policy, with wide regional variations in mask use around the country. “We estimate that statewide mask mandates gradually raise the percentage of people who ‘always’ or ‘frequently’ wear masks by around 25 [percentage points] in the 30+ days after signing,” the authors write. “Our numerical estimates are that cumulative cases grow 17.3% per week without a mask mandate but only 7.3% with a mask mandate, and that cumulative fatalities grow 29% per week without a mask mandate but only 16% with a mask mandate.”
