In a qualitative study of 375 consumers in France, Quebec, Spain and the US, respondents are asked to choose between pairs of actual food labels and to describe the reason(s) for their choice. The food labels included sustainability labels (eco-labels, Fair Trade, origin) as well as product attribute (e.g. quality, kosher) and health/nutrition labels. Respondents' reasons were coded in the original language using the same coding system across all four nations to examine their preferences for label message, design and source. We also examined the role of consumers' values, beliefs and experiences on their label choices. The coding system was drawn from a review of theoretical and empirical literature and provides a conceptual framework we call the Label Consumer Interaction model for evaluating consumers' food label preferences. Although this is case study, the results point to substantial differences across nations in terms of preferred labels, as well as the rationale for their choice in terms of attributes of the labels and consumer characteristics.
