Price

This paper provides an extensive analysis of the demand for cigarettes based on longitudinal data drawn from the South Africa National Income and Dynamic Study (NIDS: 2008 - 2014). We compare the results of the pooled OLS (POLS), the standard two-part model, the random and the fixed effect (RE, FE) panel regression. Like previous evidence into cigarette prices, we obtain negative price elasticity of demand for cigarettes, with the conditional elasticity (POLS and RE estimates) signicantly smaller than the total price elasticity (two-part model estimates).
