Goldman Sachs says a national mask mandate could slash infections and save economy from a 5% hit

CNBC: “A federal face mask mandate would not only cut the daily growth rate of new confirmed cases of Covid-19, but could also save the U.S. economy from taking a 5% GDP hit in lieu of additional lockdowns, according to Goldman Sachs. Jan Hatzius, Goldman’s chief economist, said his team investigated the link between face masks and Covid-19 health and economic outcomes and found that facial coverings are associated with sizable and statistically significant results. “We find that face masks are associated with significantly better coronavirus outcomes,” Hatzius wrote in a note to clients. “Our baseline estimate is that a national mandate could raise the percentage of people who wear masks by 15 [percentage points] and cut the daily growth rate of confirmed cases by 1.0 [percentage point] to 0.6%.” “These calculations imply that a face mask mandate could potentially substitute for lockdowns that would otherwise subtract nearly 5% from GDP,” the economist added. He first focused on to what extent, if at all, the actual use of face masks reduces the infection rate of Covid-19 by looking at differences in population behavior by state. For example, Hatizus found only about 40% of respondents in Arizona say they “always” wear face masks in public, compared with nearly 80% in Massachusetts..”
