Participants will be told that their coworker has no dietary restrictions and is trying to eat healthier. They will be presented with two similar restaurant meal options, one priced higher than the other, with randomized assignments. In the label condition, a nutritional label for healthy foods, called the Healthy Choice Symbol adopted in Singapore, will be provided with an explanation of the labelling system. For both label and non-label conditions, participants will be asked to assess the healthfulness of each option using a standard 5-point scale (1-least healthy to 5-healthiest).

While existing research has established a link between FOP labels and consumer choices, the interplay between product types, consumer perceptions, and label effectiveness is underexplored. This study examines: 1) whether consumers perceive healthier food item as more expensive when healthiness is less obvious; 2) how FOP labels mediate the relationship among product characteristics, price, and consumer's belief about food healthiness and price on choices; and 3) whether food choice changes given a price, with and without FOP labels, are more prominent for products where the perceived healthiness by consumers significantly differs from label indications. The investigators will conduct experiments with online panelists in Korea and Singapore in two settings: restaurant menus and grocery items. Results will inform more impactful nutritional information policies for healthier food choices and improved population health.",[68],"Consumer Behavior",[70],"Front-of-pack labelling","NOT_YET_RECRUITING","2025-09-21",{"date":74,"type":75},"2025-09-23","ACTUAL",{"date":77,"type":62},"2025-10",{"date":79,"type":62},"2025-12",{"name":5,"class":6}]
