Health-related factors on tobacco consumption in Turkey

In this study, we analyzed the role

of individuals’ health-related factors along with socio-demographic and

economic characteristics on both the likelihood of tobacco consumption and

quantity demanded levels using two competitive econometric methods: double

hurdle model versus hyperbolic sine double-hurdle model. Statistical tests

confirmed the dependency errors between the prevalence rate of smoking and the

consumption level, whilst the inverse-hyperbolic sine double-hurdle model data

fits best in describing the normalization of the data and the two data generating

processes: the probability and consumption levels of cigarettes. Also, the

variance-covariance of the selected model as a function of additional exogenous

variables are confirmed, while the error terms between the likelihood to smoke

and the consumption levels are positive and statistically significant,

indicating that holding control variables fixed, the uncontrolled variables out

of the system that increase the prevalence rate of smoking also boost the

consumption level, or vice versa. Many individual disease variables are significant

in both equations, breaking new grounds

in literature for identifying how both the prevalence rate of smoking and

amount have shaped.
