Lockdown effects in US states: an artificial counterfactual approach	2020-09-28		.txt	text/plain	4850	271	59	We adopt an artificial counterfactual approach to assess the impact of lockdowns on the short-run evolution of the number of cases and deaths in some US states. On average, for treated states, the counterfactual accumulated number of cases, according to the method adopted here, would be two times larger were lockdown policies not implemented. 7 Hence, the in-sample period used to estimate the synthetic control ("before" the lockdown policy) for each treated state (to be defined below) is the number of days between the tenth day after the first confirmed case and the tenth day after the lockdown strategy was implemented. On average, according to the synthetic controls, the counterfactual accumulated number of cases would be two times larger were lockdown policies not implemented in treated states.	./cache/cord-236070-yao5v598.txt	./txt/cord-236070-yao5v598.txt
