Estimates of the demand for cigarettes in Turkey uncovered significant effects from prices, incomes, education and health scares. The previous study did not pre-test for the presence of unit roots. This note reports the undertaking of this task, and the results of cointegrating regression...

Greek cigarette comsumption is examined by combining work by Zanias (1987) and Becker et al. (1994). Application of Becker et al.'s lead consumption term to the Zanias model yields results that do not strongly support the rational addiction model and show price and income as insignificant.

This paper estimates Becker's rational addiction model using a demand for cinema equation. The results do not seem to be strongly supportive of the rational addiction model. As in Becker, Murphy, Grossman we find a significant coefficient on the lead consumption term and a quite plausible...
