The price elasticity of heated tobacco and cigarette demand: Empirical evaluation across countries.

The market for heated tobacco products (HTPs) has grown rapidly in recent years, and many governments have started to include HTPs in tax codes to regulate their use. Currently, the evidence on how HTP prices impact tobacco use behaviors or whether consumers consider them as economic substitutes for cigarettes is lacking. This study is the first to answer these questions with a unique database to assess the own- and cross- price elasticities of HTP and cigarette demand. We collect a unique database of quarterly retail prices and sales of heated tobacco units and comparable scale cigarettes from 2014 to 2022, available for most countries where both HTPs and cigarettes are sold, and estimate the own- and cross- price elasticities of cigarette and HTP demand using a seemingly unrelated regression model. We find that HTP demand is price elastic (i.e., sensitive to prices) and has an own-price elasticity of -1.2 to -1.3, about four times greater than the own-price elasticity of cigarettes, which is about -0.3. We also find that cigarettes and HTPs are weak economic substitutes: while HTP demand is responsive to higher cigarette prices, cigarette demand is not sensitive to HTP prices. Our results suggest that tax policies that increase HTP and cigarette prices simultaneously will reduce HTP consumption without increasing cigarette consumption.
