Data come from the Tobacco Consumption Survey conducted in Vietnam in 2017–2018 by DEPOCEN. All regressions are weighted by using sample weight. SEs clustered in accordance with the survey design are reported in parentheses. *, ** and *** denote 90%, 95% and 99% significance levels, respectively. Since all packs of the most popular brand collected are licit, and almost all of them are found in the North, dummies for illicit cigarettes and regions are excluded from the second regression. The dependent variable is our estimated price elasticity at the individual level.
