Cigarette smoking and self-control.
This paper empirically studies time inconsistent preferences in the context of cigarette smoking behavior. With hyperbolic discounting, an individual has time inconsistent preferences, which give rise to a lack of self-control, i.e., she may perpetually postpone the execution of a plan. This implies that a smoker who wants to quit has a demand for control devices, e.g., a smoking ban in public areas or a hike in cigarette excise taxes. This paper empirically tests this implication, using a sample that is based on survey data from Taiwan. The estimation results indicate that a smoker's intention to quit has a positive effect on the smoker's support for smoking bans and a cigarette excise tax increase. These results lend support to the validity of the time inconsistent preferences in the context of cigarette smoking behavior. This casts doubt on the validity of the assumption that individuals have time consistent preferences in Becker and Murphy's [Becker, G.S., Murphy, K.M., 1988. A theory of rational addiction.
