Placebo regression estimates of the impact of the regime change on the fraction of NYS smoking households which usually purchase premium-brand cigarettes—NHP-Full.

Notes: The models used to generate the estimates above use only observations gathered prior to the regime change in June 2011, which accounts for the smaller sample size (N=17,244 which is generated by 1,565 households), relative to our main NHP-Full estimates in Table 2. Standard errors clustered at the zip code level are in parentheses.
