Abstract (EN)

An organic label offers a market signal for producers of organic food products. In Western economies, the label has gained high recognition, but organic food still represents a small part of total food consumption, which raises questions about the label's efficacy. By considering organic labels as a signal of quality for consumers, this article studies how this signal interacts with brand signals when both are visible to consumers, applying a cobranding framework. This research examines the moderating effect of the brand on organic label effects. In a 2 × 2 experimental design using real consumers (N = 122) in a shopping context, it found that, depending on brand equity, the marginal effect of organic labelling information in terms of perceived product quality varies. In particular, when brand equity is high (low), the organic label appears less (more) effective. However, regardless of the brand equity level, an organic label makes the environmentally friendly attribute salient, which has a positive impact on perceived quality. Pertinent implications for marketing and public policy are discussed.
