Notes: ∗∗∗p < 0.01, ∗∗p < 0.05, ∗p < 0.1. Results of RDD using the optimal bandwidths based on Imbens and Kalyanaraman (2012). Clustered standard errors in parentheses are robust to within-day and within-country serial correlation. All indexed are taken from “display” version of OxCGRT which will extrapolate to smooth over the last seven days of the index based on the most recent complete data. All regressions include country dummies and week dummies. Control variables are daily temperature and rainfall.
