Analyses using individual-level data (i.e., data that report the amount of alcohol consumed by specific persons) suggest that alcohol demand may be even more responsive to price than these estimates indicate, possibly because this approach can obtain differential price responses among respondents of different age groups (Leung and Phelps 1993). More recent studies have confirmed the price responsiveness of alcohol consumption (Nelson 1999; Kenkel 1993, 1996; Manning et al. 1995).
