Alcohol demand among young people in Spain: an addictive QUAIDS

This paper analyzes the demand for alcoholic beverages among young people in Spain. To that end, we develop a theoretical model which combines elements from the Theory of Two-Stage Budgeting and the Theory of Addiction, with this being empirically translated into a Quadratic Almost Ideal Demand System (QUAIDS) in which the particular characteristics of young people are introduced by Price Scaling (PS) techniques. We then estimate this specification by using data drawn from the Spanish National Survey on Drug Use in the School Population (2000) and the Spanish National Household Survey (2000). Given that wine, beer and spirits all have normal demands, our results suggest that a tax increase imposed with the intention of reducing alcohol consumption would appear to be efficient.
