Abstract:
The EU Farm to Fork strategy (F2F) promotes the compulsory adoption of a nutritional front of pack label to improve the diets of the citizens, supporting healthier food choices. In the public debate, Nutri-Score (NS) is the most favored candidate. Although being widely supported, oppositions on the political and producer levels are raised against the NS, due to the economic impact it could have on specific food sector, and specifically on Geographical Indications (GIs). Recent literature has stressed the need to explore it in more detail. The current study contributes to fill this gap by analyzing consumers' monetary preferences for GI products labelled with different NS levels. An incentivized non-hypothetical experiment was conducted on 188 Italian consumers. Different products representing different levels of NS were used. Specifically, a conventional pasta and the Pasta di Gragnano PGI (NS = A), a conventional flatbread (piadina) and the Piadina Romagnola PGI (NSC), and a conventional hard cheese and the Parmigiano Reggiano PDO (NS = D) were considered in the survey. Results reveal that the NS elicits favorable responses and unfavorable reactions in consumers' preferences, aligning with expectations for A and D scores, respectively. The perceived healthiness of the product significantly affects consumers' WTP, increasing it. Results stress the need to have effective communication strategies within the EU to reach the F2F goals. NS diminishes the premium in prices associated with GIs independently from its level, when considering those consumers who value more the GIs. However, the most well-known GIs does not suffer from this negative effect of the NS, as the positive value associated to the GI offset the negative effect of the NS.
