Abstract

Sin taxes are increasingly being used to discourage the consumption of goods perceived to harm individuals and society. This paper examines the impact of South Africa's Health Promotion Levy (HPL)—the first sugar tax implemented in Africa—on the consumption of sugar-sweetened beverages (SSBs) in the country. Using comprehensive data from excise returns submitted by manufacturers and importers of SSBs, we find that the HPL was extremely effective in reducing the consumption of sugar through these beverages.
