Tax Policy

Participants will be assigned to one of four conditions: (i) nutrient warning labelling and no taxation, (ii) nutrient warning labelling and taxation, (iii) current traffic light labelling and taxation or (iv) a control condition (current traffic light labelling and no taxation). Participants will complete a food ordering task using a simulated online supermarket resembling a major UK retailer (Tesco), before purchasing their selected items for delivery/collection via the retailer. Food choices will be recorded, and participants will self-report intake of purchased food items.
