Weighted logistic regressions also controlled for duration dependency, time-varying age, age squared, gender, a dummy of residing in rural areas at the time of survey, and state fixed effects. Standard errors were clustered to adjust for inter-temporal correlations within the same individual. Elasticity esimtates for significant negative associations between cigarette prices and smoking onset are −2.4 (Column1) and −2.5 (Column5). Elasticity esimtates for significant associations between bidi prices and smoking onset are −4.8 (Column4), −1.0 (Column5), and −2.2 (Column 6).
