Food Beliefs: Elicitation,Estimation and Implications for Labeling Policy

We present a model in which consumers use product attributes (or labels) and their own beliefs to form expectations about the quality of a product. We use best–worst scaling to elicit beliefs, and study how information may influence these beliefs. In our ranking experiments, participants sort different milk products according to (perceived) nutritional or environmental quality, and we use the resulting choice data to recover beliefs econometrically. In a nutritional quality experiment, we measure how food labels (i.e. front‐of‐package, back‐of‐package and ratio of recommended to restricted nutrients) alter consumers’ beliefs, finding that truthful attribute information may sometimes mislead consumers. The discussion explains how similar experiments could be used to distinguish informative labels from marketing messages.     

Combining Stated and Revealed Preferences on Typical Food Products: The Case of Dry‐Cured Ham in Spain

An extensive body of research concerns the valuation of EU certification schemes of quality based on the origin of food products. This literature focuses mainly on stated preferences (SPs) and reported behaviours by the consumers. We combine consumers’ SPs, obtained through a conjoint ranking experiment, with revealed preferences (RP), obtained through a retail scanner database. We evaluate SPs as predictors of RP, and investigate whether SPs and RPs are consistent. Dry‐cured ham in Spain is chosen as the anchor product, mainly because of its broad customer base and long history of origin certification. A ‘trick’ nested logit model with non‐identical and identical samples of consumers is estimated to answer each of the objectives. Results show that, irrespective of the analysed samples, SP can predict general market trends and choices but not accurately predict market shares, and that consumers’ actual behaviour is partly consistent with their SPs. We find that consumers prefer ham produced in Teruel, compared with unspecified Spanish origin. Quality Certification and a Distributor’s Brand are preferred over the alternatives of no quality label or identified with a brand owned by the producer. Interestingly, SPs for the Quality Certification and the distributor’s brand lead to an over‐ and under‐estimation, respectively, of the market share.     

Consumption effects of genetic modification: what if consumers are right?⋆

This paper develops a model of differentiated consumers to examine the consumption effects of genetic modification (GM) under alternative labelling regimes and segregation enforcement scenarios. Analytical results show that if consumers perceive GM products as being different than their traditional counterparts, GM affects consumer welfare and, thus, consumption decisions. When the existence of market imperfections in one or more stages of the supply chain prevents the transmission of cost savings associated with the new technology to consumers, GM results in welfare losses for consumers. The analysis shows that the relative welfare ranking of the ‘no labelling’ and ‘mandatory labelling’ regimes depends on: (i) the level of consumer aversion to GM products; (ii) the size of marketing and segregation costs under mandatory labelling; (iii) the share of the GM product in total production; and (iv) the extent to which GM products are incorrectly labelled as non‐GM products.     

The role of certificate issuer on consumers’ willingness‐to‐pay for milk traceability in China

In response to increasing concerns about domestic food safety issues, establishing tracking systems in the food industry is mandatorily required under newly launched food safety laws. However, the kinds of monitoring and certification systems that should be set up to ensure practical adoption and the effectiveness of the regulation remain unclear. This study aims to analyze consumers’ preferences for milk traceability, with particular interest in investigating how consumers’ preferences could be affected by monitoring and certification systems of the regarding system. Survey data from a choice‐based conjoint (CBC) experiment are used to achieve this objective. In the experiment, milk is defined by a set of attributes in which we assume that milk traceability can be certified by three entities: the government, an industrial association, and a third party. The CBC data are then analyzed by using the alternative‐specific form of a conditional Logit (McFadden's Choice) model. We found that urban Chinese consumers have a strong desire for traceable milk, but their preference for traceable milk is significantly related to the associated certificate issuers. Currently, the highest willingness‐to‐pay goes to government certificated traceable milk, followed by industrial association certificated and third‐party certificated milks. In the future, however, consumers are likely to give more credit to third‐party certification with rising income and knowledge.     

Labels for a Local Food Speciality Product: The Case of Saffron

We examine the potential demand for a local food speciality product, saffron, with alternative labels, using a choice experiment. The paper contributes to the literature on credence attributes, by examining Willingness to Pay (WTP) for the local, organic and PDO (Protected Designation of Origin), their differences across experimental conditions (hypothetical and non-hypothetical), and by identifying the effects of personal characteristics, in terms of socio-demographics and level of product involvement on the differences in WTP. We find that the local saffron speciality has an important appeal that could be better reinforced with the PDO rather than the organic labelling, and that consumers show a consistent pattern of preferences across experimental environments. WTP tends to be higher in the hypothetical setting and, in particular, consumers with relatively more knowledge and deeper roots in the territory tend to exhibit a larger WTP premium for local origin and its certification. These results may help producers improve their marketing of agri-food products with a high gastronomic value and differentiation potential, while they warn about an overstatement of WTP for socially desirable characteristics, such as organic labelling, which is also relevant for policymakers.     

Are multiple labels on food products beneficial or simply ignored?

This study examines consumer preferences and willingness to pay (WTP) for organic wheat products exhibiting single labels, as well as multiple labels, including organic. The additional labels considered are related to the organic label (non-genetically modified organism [non-GMO]) or perceived as health-promoting (gluten-free, low-carb, sugar-free). Study data were collected using a consumer survey conducted online in 2017 across 16 U.S. western states and analyzed using random parameter logit models. Findings show that organic-labeled wheat products with additional claims were valued equally or less than the organic only version. Overall, consumer higher objective and subjective knowledge of organic standards, as well as preferences for gluten-free products, increased their WTP for organic wheat products. Consumers unfamiliar with organic standards valued the non-GMO label over the organic label. Additionally, consumer WTP for health-related claims on hedonistic products was low or even negative. Hence, multiple labels on organic products generally provide no additional consumer benefit and are likely ignored. Study findings suggest that using the claim that most distinguishes the product, or is most salient, may improve product pricing. Also, non-GMO certification rather than organic certification should be considered for some markets. Finally, consumers with preferences for gluten-free products represent a potential market for organic wheat products.     

Ecuadorian Farmers Facing Coffee and Cocoa Production Quality Labels

Quality labels refer to the adoption of voluntary standards by producers to highlight the quality to consumers and customers. Usually in agrofood, these focus on aspects of production systems and intrinsic characteristics of products. In agricultural production, quality labels focusing on ethical and environmental aspects have a high spectrum globally. The objective of this study was analyzing the farmers’ perceptions toward production with quality labels in cocoa and coffee in Ecuador. The information used comes from the development of two focus group sessions and 157 surveys addressed to producers. According to the results, environmentally friendly production systems represent an advantage and a disadvantage for farmers. When comparing farmers who produce with and without quality labels, it was found that issues related to market access are further motivating farmers to produce superior quality. Finally, from the producers’ point of view, the premium price paid for product certification is debatable.     

Consumers’ preferences for fresh broccolis: interactive effects between country of origin and organic labels

While international trade in organic products has grown significantly, understanding consumers’ preferences for imported organic foods has remained limited. This research examines the impact of country‐of‐origin labeling on US consumers’ choices of organic foods. Results show that consumer valuation of domestically produced organic broccoli was significantly higher than that of imported organic broccoli. Adding information about USDA organic certification standards/rules for imported products mildly increases consumer valuation of imported organic broccoli in some cases. These findings suggest that providing such information may have a positive impact on consumer willingness to purchase imported organic products.     

Consumers’ Perceptions and Behaviors Regarding Organic Fruits and Vegetables: Marketing Trends for Organic Food in the Twenty-First Century

ABSTRACT

Organic food market is very challenging in Europe and developing rapidly with different rates between the western and eastern parts. The objective of this report is to gain knowledge about attitudes toward organic fruits and vegetables among Slovenian consumers. Results indicated that organic buyers tend to be younger and higher educated than those who do not buy them. In addition, consumers’ trust in the authenticity of the goods and price are also issues. However, the main barrier to increase the market share of organic products is consumer information. According to the research results an important task for the producers will be to increase consumers’ knowledge of what an organic product is and how to differentiate it in the marketplace. Along with knowledgeable and educated consumers, consumption could be raised on another level. The results of the research could be used for planning further marketing activities.     

Do consumers value hydroponics? Implications for organic certification

Recent controversy about the inclusion of hydroponics in the U.S. Department of Agriculture (USDA) organic program has highlighted uncertainty about marketing hydroponic crops. In a controversial vote in November 2017, the National Organic Standards Board chose not to recommend that hydroponic farms be banned from organic certification. It is still unclear, however, how consumers perceive and value hydroponic production. This study used a nonhypothetical choice experiment to estimate consumers’ willingness to pay for hydroponic and traditional lettuce both with and without organic certification. No hydroponic premium was found, but exposing consumers to different kinds of information about hydroponics significantly affected consumers’ preference formation. Findings generally suggest that the National Organic Program should consider ways to ensure the stability of organic premiums as perceptions about hydroponics evolve.     

Economic Effects of the Consumer‐oriented Genetically Modified Products in Markets with a Labelling Regime

This paper builds on the literature on the economic effects of the second‐generation, consumer‐oriented genetically modified products (GMPs). It analyses the market and welfare impacts of the introduction of these new products in markets, like the EU, that mandate the segregation and labelling of the first‐generation, producer‐oriented GMPs. Developing an empirically relevant model of heterogeneous consumers and producers, the study determines the effects of the consumer‐oriented GMPs on the markets of conventional, GM and organic products, and the welfare of consumers and agricultural producers. Analytical results indicate that the market effects of the new GMPs are case specific and depend on: (i) the consumer valuation of the quality‐enhancing attribute of the new GMP; (ii) the level of consumer aversion to GMOs; (iii) the strength of consumer preference for organic products; and (iv) the production costs and marketing margins in the different supply channels. The policy on the labelling of the first‐generation GMPs does not affect the impacts of the second‐generation GMPs on the quantities and market shares of the different products. However, it does affect their price effects and welfare implications. The introduction of consumer‐oriented GMPs under a mandatory labelling regime can result in losses for some GM consumers and all producers of the conventional product.

Estimating product‐specific and multiproduct economies of scale with data envelopment analysis

Nonparametric cost frontier estimation and subsequent analysis of the relative efficiency of firms has historically been conducted without critically examining the shape of the cost frontier. The shape of the cost frontier has been examined using additional parametric estimation methods to recover potential cost savings from multiproduct and product‐specific economies of scale. This paper presents and tests an approach to estimate multiproduct and product‐specific economies of scale using data envelopment analysis. Data for the study are simulated assuming an underlying production technology. Nonparametric estimates of efficiency, multiproduct scale, product specific scale, and scope economies are compared to those of the assumed production technology. Results show that the nonparametric approach accurately estimates multiproduct economies of scale and product‐specific economies of scale under alternative inefficiency distributional assumptions.     

Chinese consumers’ willingness to pay for pork traceability information—the case of Wuxi

In this study, consumers’ willingness to pay for farming, slaughter and processing, distribution and marketing, and government certification information was investigated in Wuxi, Jiangsu Province, China using an experimental auction and real choice experiment based on incentive compatibility of the nonhypothetical elicitation method. No significant differences in consumers’ willingness to pay were revealed by the experimental auction and real choice experiment on the whole, and results from both nonhypothetical experimental methods demonstrated that consumers were willing to pay certain premiums for all four types of traceability information and had the highest willingness to pay for government certification information. These results indicate that consumers trust in pork safety protection under governmental supervision. Moreover, it was found that government certification information played a significant role in improving consumer utility, demonstrating that consumers paid close attention to safety risks in farming. Therefore, this study predicts that the introduction of governmental supervision into the pork traceability system and establishment of a system for collecting traceability information starting from the stage of pig farming will play important roles in meeting consumer demands for pork quality and safety, as well as promoting the development of traceable food policies.     

When Consumers and Products Come From the Same Place: Preferences and WTP for Geographical Indication Differ Across Regional Identity Groups

ABSTRACT

This article contributes to the existing literature on geographical indications by observing consumers’ stated preference for extra-virgin olive oil in two groups differing in their regional identity. In particular, consumers from two groups were asked to rank products in a contingent ranking survey. One group (“insiders,” Sicilian consumers) shared origin with a good product (Sicilian oil); the other group (“outsiders,” Rome and Milan) presented “no association” consumer-product. Results indicate that insiders are willing to pay more for goods originating from the region they identify with compared with a region associated with outsiders. Identity seems to give a bias by which a local product is not necessarily perceived as superior in absolute terms, but in relative terms: outside products are never considered better than inside options but are either inferior or equal in perceived value.     

Producer–Consumer Misalignment as a Possible Cause for New Food Failure: Empirical Evidence From Chile

Literature on new food products development agrees on the importance of gaining knowledge about consumer tastes and preferences as a way to increase new product success. However, the failure rate of new food introductions continues to be high. In economies with a highly developed retail system, retailers and other market players create an information and communication barrier between the producer and the consumer. Consequently, the development of new products becomes difficult in such conditions, since misalignments between producers and consumers are more likely to occur. To investigate the issue, we interviewed producers of Chilean companies in the blueberry, plum, and wine industries and concluded that their product design was based on assumptions about consumers’ preferences and on the observed market response to competitors’ products. To test if these assumptions were correct, we compared them to consumer preferences. Results showed that producers’ assumptions about consumer preferences differ significantly from actual consumers’ preferences.     

Consumers’ Trust in Food Quality and Willingness to Pay More for National Parks’ Brands: Preliminary Evidence From Italy

In Italy, national parks allow the use of their brand logo and name on the labels of food products produced by firms located within the national parks. However, no empirical research has yet investigated the impact of national park brands on consumers’ attitudes and behaviors. Hence, this empirical study explores the factors that influence consumer trust in food quality and their willingness to pay premium prices for the national park brands. Results from a survey involving a sample of 227 Italian consumers suggest that women and younger consumers trust more and are more willing to pay for national park brands. The origin of food products associated with national parks, naturalness of foods, food quality certifications and branding, and the environment in which the packaged foods originate influence consumer confidence and buying behavior. Implications for food marketers and policymakers are discussed.     

Does willingness to pay increase with the number and strictness of sustainability labels?

Labels signaling sustainable product attributes are gaining importance, although uncertainty concerning the environmental, micro‐ and macroeconomic benefits of such labels persist. One of the questions still incompletely answered is whether Willingness To Pay (WTP) varies with a gradually increasing number of labels on a food product. In order to answer this question, we conducted a laboratory experiment with 191 student respondents, testing consumer valuations of different labeling strategies. Using the Becker‐DeGroot‐Marschak mechanism, WTP for 15 food products was measured. The products were endowed with up to six different sustainability labels, such that each grocery item was available in eight product versions. For perishable, nonperishable, and plant‐based products, the results indicate that participants are prone to allocating WTP‐premiums to labeled products, more than to unlabeled products. For animal products, however, labels do not influence WTP significantly. Furthermore, the premiums do not vary with an increasing number of labels, irrespective of whether the labels signal substitute or complementary sustainability information. The results are not entirely in line with normative notions of magnitude variation, but rather with the behavioral economic concept of embedding effects.     

Alcohol Tax,Price–Quality Proxy and Discounting: A Reason Why Alcohol Taxes May Rebound

The increasing concern about the external costs of alcohol consumption has often led economists and policy‐makers to advocate taxes to internalise the social costs and target consumption. However, in certain markets for alcoholic drinks – particularly wine – price is not only a cost but also an indicator of quality, guiding consumer choice. There is, perhaps, a higher probability of ex post satisfaction with products at higher prices in a market with potential adverse selection. The price–quality proxy interacts with discounts, where the full price of the product before discount (referred to as the External Reference Price in the marketing literature) is used as a quality reference. This study shows that an alcohol tax in the presence of discounting may increase the perceived value of the product, and therefore persuade consumers to prefer the purchase of more expensive wines with the highest discount. As a consequence, consumers could favour products with higher alcohol content – which contradicts the objectives of the policy. Consequently, for an alcohol tax to be effective discounting of alcoholic beverages (in particular, wine) should be regulated to avoid the policy backfiring.     

Consumers’ Valuation of Rice‐Grade Labeling

The current Korean rice‐grading system has a “no test” option that allows rice to not be graded in the market. This study examines Korean consumers’ valuation of a rice‐grading system without the “no test” option. We apply a nonhypothetical experimental auction to elicit consumers’ willingness to pay for each rice grade and identify the impact of the provision of additional grading information on product valuation. We then use contingent and inferred valuations to obtain consumers’ valuation of a mandatory rice‐grading system without the “no test” option. We find that Korean consumers are willing to pay an additional premium for each rice grade and that rice‐grading information is the most important factor that differentiates the rice products. Rice consumers in Korea also strongly prefer a mandatory rice‐grading system without the “no test” option.
