Note(s): Results are from a PPML. Coefficients from the table can be expressed as semi-elasticities by 100*(exp(Covid) - 1). Standard errors appear in parentheses. Standard errors are clustered at the store level. ***, **, and * denote statistical significance at the 0.01, 0.05, and 0.1 level, respectively
