With much of the U.S. in shutdown mode to limit the spread of the COVID-19 disease, a debate has sprung up about when the country might “reopen” commerce, to limit economic fallout from the pandemic.

His study of the 1918 flu pandemic shows U.S. cities which responded more aggressively in health terms also had better economic rebounds.
