AimsTo model the effects of a range of alcohol pricing policies on alcohol consumption in subpopulation groups (e.g. alcohol consumption pattern, and age and income groups) in Australia.DesignWe used estimated price elasticities to model the effects of proposed pricing policies on consumption for 11 beverage categories among subpopulation groups.SettingAustralia.ParticipantsA total of 1789 adults (16+ years) who reported they purchased and consumed alcohol in the 2013 Australian International Alcohol Control Study, an adult population survey.MeasurementsMean and percentage changes in alcohol consumption were estimated for each scenario across subgroups. The policy scenarios evaluated included: (1) increasing the excise rate 10% for all off-premise beverages; (2) replacing the wine equalization tax with a volumetric excise rate equal to the current spirits tax rate; (3) applying a uniform excise tax rate to all beverages equal to the current sprits tax rate and a 10 or 20% increase in it; and(4) introducing a minimum unit price (MUP) on all beverages categories at $1.00, 1.30 or 1.50.FindingsThe effects of different tax and MUP policies varied greatly across different subgroups. The effects of the MUP policy on alcohol consumption increased rapidly in the range from $1.00 to $1.50. Applying a uniform tax rate across all beverages equal to current spirits tax rate, or a 10 or 20% increase beyond that, could generate large reductions in overall alcohol consumption in Australia. Compared with the uniform tax rate with or without further tax increase, introducing a MUP at $1.30 or $1.50 could reduce consumption particularly among harmful drinkers and lower-income drinkers, with comparatively smaller impacts on moderate and higher-income drinkers.ConclusionsBoth uniform excise tax and minimum unit price policies are predicted to reduce alcohol consumption in Australia. Minimum unit price policies are predicted to have a greater impact on drinking among harmful drinkers than moderate drinkers.© 2020 Society for the Study of Addiction.
