An article by Judit Vall Castelló (IEB-UB and CRES-UPF) and Guillem López Casasnovas (UPF, CRES, and BSE) analyzes the effects of the tax on sugary beverages on their sales and consumption in Catalonia. The results show a 22% reduction in their consumption compared to before the introduction of the tax, meaning an intake of 107 calories less per person per week among consumers.
