Price smoking participation elasticity in Colombia: estimates by age and socioeconomic level.

PPE for Colombia is above estimates for comparable middle-income countries such as Mexico. As a result, current estimates for health gains of tax policies are likely to be underestimated. Moreover, in contrast with the literature, we find that the PPE for the youth (≤25 years) is lower than older age groups, and there is no evidence of a prominent socio-economic status (SES) gradient.
