This article uses survey data obtained from Taiwan to investigate cons
umer perceptions of smoking risks and the linkage of these perceptions
to smoking behavior. In our analysis, two equations are estimated: (1
) risk perception, and (2) smoking probability. The simultaneity probl
em in estimating risk perception and smoking probability is also consi
dered. Overall, the results indicate that the risk perceptions of ciga
rette smoking are substantially overestimated and that these risk perc
eptions in turn, have a significantly negative effect on smoking proba
bility. Also, the results suggest that the determinants of risk percep
tion are consistent with the predictions of a Bayesian learning framew
ork.
