Decoding the Interplay of Front-of-Pack Labels, Price, and Consumer Perceptions: Impact on Food Choices in Korea and Singapore

"The intervention combines either a front-of-pack (FOP) label that frames high nutrition or no FOP label with price variation. Products are randomly assigned to either receive a positively-framed FOP label or no label, and to either a high or a low price.~This yields four experimental arms:~1. Positively framed FOP label with high price~2. Positively framed FOP label with low price~3. No label with high price~4. No label with low price"

"The intervention combines either a graded front-of-pack (FOP) labelling or no FOP labelling with price variation. Products are randomly assigned to either receive a graded label or no label, and to either a premium or an average price.~This yields six experimental arms:~1. High grade (A) with premium price~2. Low grade (D) with premium price~3. No label with premium price~4. High grade (A) with average price~5. Low grade (D) with average price~6. No label with average price"
