Abstract

The paper presents estimates of price elasticities of demand for 12 disaggregated alcoholic beverages in Australia: premium beer, full strength beer, low alcohol beer and mid-strength beer; red bottled wine, white bottled wine, sparkling wine, cask wine; dark and light ready-to-drink (RTD); and dark and light spirits. These disaggregated categories correspond closely to the commodities of interest to public policymakers with respect to taxation and health policies. The system of demand equations is estimated with Nielsen s data using a semiflexible Almost Ideal Demand System model in order to impose negative semi-definiteness on the demand parameters. Results indicate elastic own-price elasticities for virtually all commodities. Cross-price elasticities suggest that beverages most linked with negative externalities, namely full strength beer, dark RTD and dark spirits, may need to be taxed jointly. Any proposed tax increase to cask wine may also result in consumers shifting demand to more undesirable beverages. The elasticity estimates are used to illustrate the effect of a hypothetical change towards taxation equalisation based on alcohol content. These elasticities offer crucially needed inputs for analysing any tax change policies.
