Taxation Online Experimental Supermarket

Scientific context The increase in the consumption of unhealthy food coupled with a suboptimal consumption of healthier options have increased the risk of non-communicable diseases (NCD) worldwide. Among other public policies to address the rise in NCD -such as front of pack labelling, regulation of food and beverages in schools, marketing regulations targeted to children- taxation has been recognized as a cost-effective strategy to reduce consumption of taxed products. Although subsidies have been used to reduce food insecurity, with the rise in NCD associated with unhealthy diets, studies have explored the feasibility of combining subsidies to incentivize the consumption healthy food with taxes on unhealthy options. The impact of prices on dietary behaviour of consumers has been demonstrated in experimental designs as well as in economic analysis of observational data on purchases. Alt
