Notes: The table reports the intervention decisions made by the U.S. government during the COVID-19 epidemic. The main source is Hale et al. [1], which tracks government responses in countries around the globe to the COVID-19 epidemic. The interventions are sorted by their chronological appearance during the epidemic. The first column presents the ID of each intervention, where e, c and h are abbreviations for economic, closure and health government measures, respectively. We also defined an additional event that corresponds to e3, when President Trump signed a $100 billion aid package as part of the war against COVID-19.
