We relax these assumptions by endogenizing both societal and parental preferences. We use smoking as a case-study of a cultural trait which did not always exist, and which over time has switched from being perceived as socially acceptable to being perceived as undesirable. In our model, parents' preferred cultural traits depend on the perceived health costs of smoking, and societal preferences depend on the behavior of a tobacco industry that aims to maximize smoking prevalence. We derive conditions for the emergence and persistence of the smoking habit, and find new implications for the relationship between parental and societal influences. We then test explicitly for the validity of our theoretical framework using novel US data. We find that our framework is able to capture features of smoking behavior which existing models are unable to explain.

This paper examines whether and how these rates change when one adjusts for differential mortality of smokers and non-smokers. generate life-course smoking prevalence rates by age-cohort. With cause-specific death rates from secondary sources and an improved method, we correct for differential mortality, and we test whether adjusted and unadjusted rates statistically differ. With US data (National Health Interview Survey, 1967, we also compare contemporaneously measured smoking prevalence rates with the equivalent rates from retrospective data.
