简要总结

The global epidemic of obesity and chronic diseases has led to widespread use of front-of-package (FOP) nutrition labels. 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.

详细描述

The investigators will conduct experiments in both Korea and Singapore, focusing on two settings with various food items: restaurant menu choices and grocery item selections. For each item, investigators will elicit consumers' prior belief about its healthiness. Our research builds upon the work of Haws et al. (2017), which demonstrated that US consumers tend to overgeneralize their belief about "expensive=healthy" to product categories where it is not true. This tendency potentially biases perceptions of healthy foods. The investigators aim to test this "expensive=healthy" intuition and its impact on food choice, with and without FOP labels, in Asian contexts. The investigators hypothesize that absent FOP labels, consumers will infer healthiness from price information (i.e., this product is expensive, so it must be healthy) and that providing FOP labels will reduce the reliance on this inference. The investigators also hypothesize that such effects of FOP labels are more prominent for products where the perceived healthiness by consumers significantly differs from the healthiness indicated by the labels. When the FOP labels show 'less healthy' for those expensive and perceived as 'healthy' products, consumers will update their prior belief about its healthiness and be more likely to drop the intuition 'expensive=healthiness' in decision-making and respond to a greater extent.

主要结局

Consumers behavior

时间窗: Participants are expected to complete the online experiment in one sitting (within 24 hours). If they are disconnected from the survey platform, they are allowed up to two attempts to resume, with access to the platform disabled after 48 hours.

Study 1: Participants achieve a response by choosing between two menu food items they would purchase for their co-worker in online experimental platform. Study 2: Participants rate their intention to purchase grocery items on a 7-point scale (1 = least likely, 7 = most likely) in online experimental platform.
