The following bibliography is conceived as a selection of international literature on food as heritage and as a marker of identity within the huge amount of works recently produced on the topic of food. The bibliography has been produced within the “Food as heritage” project, performed at University of Bologna and coordinated by Ilaria Porciani, with a team composed by Massimo Montanari, Paolo Capuzzo, Raffaele Laudani and Marica Tolomelli. “Food as heritage” is part of a wider projec...

Bibliography “Food as Heritage”

This paper assesses consumers' preferences and willingness to pay for European Union geographical indication quality labels [Protected Designation of Origin (PDO) and Protected Geographical Indications (PGI)], organic farming label and other product quality cues. Using a choice experiment, random parameter logit model and olive oil as product of interest, results suggest that respondents are willing to pay the highest premium price for a product with a PDO label, followed by organic farming label, a quality cue describing the product as extra-virgin olive oil and then a PGI label.

Consumers' valuation of food quality labels: The case of the European geographic indication and organic farming labels

Using stated preference data from Kentucky and Ohio, USA, we estimate consumer willingness-to-pay for varieties of a processed food product (blackberry jam) that are differentiated with respect to their local production labelling and a series of other value-added claims. Results show that consumers were willing to pay more for the product indicating locally produced, produced in their state or in a well-identified multi-state region. Consumers were willing to purchase organic products, although there might be some confusion as to the meaning of the organic logo. Our results also supported the notion that consumers are willing to support small family farms. , Oxford University Press.

Consumer preferences for local production and other value-added label claims for a processed food product

We conduct a meta-analysis of studies estimating price premiums for agricultural products differentiated by Geographical Indication (GI). Models accounting for differences across product characteristics (food categories) and institutions (PDO, PGI, trademarks) explain a large portion of the variance in estimated premiums. Specifically, GIs capture the highest percentage premium in markets for products with short supply chains and relatively low added value (e.g., agricultural commodities). The premium is lower for wine and olive oil, where alternative means of product differentiation (e.g., branding) exist. Controlling for product characteristics, GIs adopting stricter regulations (PDO) yield larger premiums than less regulated ones (PGI).

A Meta-Analysis of Geographical Indication Food Valuation Studies: What Drives the Premium for Origin-Based Labels?

This paper provides an analysis of consumer preferences for product claims, specifically about origin and production methods. In particular, it addresses two important questions: i) whether consumers are willing to pay a premium for food products carrying these claims; and ii) whether local and organic claims are complements or substitutes. A choice experiment designed to estimate two-way interactions was undertaken in Spain for eggs. The findings show first, that consumers are willing to pay a positive premium price for an enhanced method of production (that of barn, free-range and/or organic instead of cage produced eggs) as well as for the proximity of production (local, regional and national over imported). Second, the findings show that consumer preferences for the claims are heterogeneous with two consumer segments being identified: “origin preference”, the larger segment, and the “production method preference”. Results show that organic and local claims were complements for the larger first segment but that free-range and local/regional claims were substitutes for the second smaller segment. These results provide the marketing chains with insights applicable for pricing strategies.

Are Local and Organic Claims Complements or Substitutes? A Consumer Preferences Study for Eggs

Geographical origin labels are important information and marketing tools and have recently become a central component of EU agricultural promotion. We consider demand in a non-EU export market for two distinct label types: country of origin (COO) and geographical indications (GIs). Additionally, two types of GIs, 'protected designations of origin' (PDOs) and 'protected GIs' (PGIs) are considered. Empirical findings indicate consumers' willingness to pay varies with the oil's COO and is greater for GIs than for non-GIs from a given country. Weaker evidence that consumers value PDOs more than PGIs is also found.

Consumers’ preferences for geographical origin labels: evidence from the Canadian olive oil market

Motivated by the recognition that geography is often correlated with and/or an important determinant of the overall quality of agricultural products, consumer groups, industry representatives, and domestic and trade representatives have increasingly considered the potential role of geographical origin labels as consumer information and marketing tools. We investigate whether consumers recognize and value the informational content of a variety of nested geographical origin labels. In particular, this study disentangles and assesses three nested types of origin labels: country of origin (COOL), geographical indications (GI), and PDO/PGI. We find that, within the context of a high quality valueadded commodity such as extra virgin olive oil, consumers' willingness to pay varies across different countries of origin, and that within a country consumers have a greater willingness to pay for GI-labeled than non-GI labeled products. We also find evidence that consumers value PDOs more than PGIs, but the result is not as strong as that found for GI versus non-GI. Overall, our findings support the recent surge in interest by both developed and developing nations in reaching an agreement for stricter and more widespread protection of GIs within ongoing WTO discussions and harnessing them as marketing tools for expanding shares in export markets.

Consumer Preferences for Country-Of-Origin, Geographical Indication, and Protected Designation of Origin Labels

This paper investigates the impact of geographical origin labels on consumers' preferences. Specifically, we consider the preferences of Canadian consumers for extra virgin olive oils marketed with country-of-origin labels (COOL) and geographical indications (GIs). In contrast to previous studies, by considering a third-country market (a market different from that where production occurs), we can look simultaneously at COOL and GIs and separate the impacts of these two forms of geographical origin labels. We find that, within the context of a high quality value-added commodity such as extra virgin olive oil, consumers value both COOL and GI labels. But, in terms of the fraction of consumers with positive preferences and willingness to pay, COOL labels are valued more by Canadian consumers compared to GI labels. To better account for taste heterogeneity among consumers, we partition the sample on the basis of consumers’ choice of shopping location. We find that different consumer groups vary to a large degree in their relative valuations for COOL, GI, and organic olive oils.
