Abstract: In this study we investigate the impact of the piece-wise Catalonia Sugar Sweetened Beverages tax on household expenditure and sugar consumption. We use longitudinal scanner data on all beverage purchases in a supermarket chain from May 2016 to April 2018 by 1 million households in Catalonia and Spain. We incorporate Difference-in-Differences models into an Almost Ideal Demand System and household consumption model.

We find that households move their expenditure from high sugar pops to low and medium sugar pops. They also reduce their expenditure shares in cavas as they are complementary to pops and they reduce expenditure shares of high sugar juices. We find an overall reduction in sugar, with strongest reductions for high sugar pops and colas. We find heterogeneous effects by age and income of the households with stronger reductions for higher socio-economic groups.
