Table 3.2 gives (i) the logarithm of cigarette consumption (in packs) per person of smoking age (> 16 years) for 46 states in 1992, (ii) the logarithm of real price of cigarettes in each state, and (iii) the logarithm of real disposable income per capita in each state. This is drawn from Baltagi and Levin (1992) study on dynamic demand for cigarettes. It can be downloaded as Cigarett. dat from the Springer web site.
LNC: log of consumption (in packs) per person of smoking age (>16)
