Abstract

The global trend of diets high in sugar sweetened beverages (SSB) is associated with a high risk of obesity and non-communicable diseases (NCDs). To reduce SSB consumption on a population level, SSB taxes have become a popular policy solution. In Indonesia, although the prevalence of obesity has doubled in the past decade (11.7% in 2010 to 21.8% in 2018), SSB taxes have not yet been implemented. Utilizing the 2021 Indonesian household socioeconomic survey (SUSENAS), this study estimated price elasticities and projected the plausible effects of implementing an SSB tax on consumers’ demand for SSBs and the associated government revenue using the Quadratic Almost Ideal Demand System (QUAIDS) model. Five SSB groups were studied: 1) manufactured liquid milk; 2) sweetened condense milk; 3) instant coffee; 4) tea drinks and fizzy drinks with CO2; 5) fruit juices, “health” drinks, and energy drinks. The overall results showed that the non-milk SSB groups were price elastic. Probing deeper into the substitutions for SSB across categories, we found both substitutionary and complementary effects. Our analysis revealed that increasing SSB prices by 20% would reduce the demand for SSBs on average by 17.5% (14.3%-18.6% for each SSB group) and generate additional state revenue up to IDR 3,628.3 billion per year (approximately US$ 238.5 million or 0.2% of total tax revenue in 2022). Considering the health and economic impacts of high consumption of SSBs, this study provides empirical evidence that imposing taxes on SSBs could be an effective measure to reduce public consumption and to generate tax revenue for financing health programs that address obesity and NCDs in Indonesia.
