Yesterday the @nberpubs released our Sturgis COVID-19 paper. Dhaval Dave, @FriedsonAndrew, @Drew_McNichols, and Joe Sabia are grateful for constructive comments. Below the authors offer responses to some important questions. [1/9]

While local counties may be contaminated by the Sturgis Rally, our synthetic control results hold if we require geographically proximate (within SD and border states) donor counties with no or low Sturgis inflows. [2/9]
Moreover, if we add census division-specific time effects to our “dose response“ diff-in-diff models, which account for unmeasured regional shocks (in addition to county time trends) and require within census division county comparisons, our main findings are unchanged. [3/9]
