Behaviour Under Addiction: Dynamic Choice Between Smoking and Vaping.
I develop and estimate a dynamic discrete choice model of joint cigarette and e-cigarette use, built around two distinct but interacting product-specific addiction stocks. The two products are substitutes for all consumers, yet the strength of substitution varies sharply with prior addiction: a smoker’s sensitivity to cigarette prices weakens as smoking addiction deepens, whereas a vaper’s sensitivity to e-cigarette prices strengthens as vaping addiction deepens. The central finding is a striking asymmetry between the two taxes—a cigarette tax does little to curb smoking among the heaviest smokers, while an e-cigarette tax sharply reduces vaping but pushes former smokers and dual users back toward combustible cigarettes.
