Valuing Consumer Perceptions of Olive Oil Authenticity

Nowadays, while the authenticity of agri-food products becomes a major concern for consumers, given the increasing rate of food fraud reports across the world, olive oil records the highest adulterations. The high selling price of olive oil is the main reason for conducting adulteration, which is often caused through false indications on the packaging (mislabeling). On the other hand, consumers are well aware of the alteration, and they are looking for authenticity signals during the purchase process. Authenticity, therefore, becomes an evaluation and decision-making criterion that guides consumer choices. The aim of this paper was twofold: to highlight the attributes in which Greek consumers attach great importance during the evaluation of olive oil’s authenticity, and second, through consumers’ demographic segmentation, to gain more detailed knowledge about the attributes that consumers evaluate in olive oil authenticity. CUB (Covariates in a mixture of Uniform and Binomial random variables) models are employed for the interpretation of ordinal data due to the ability of comparing and clustering the rating distributions consumers express about olive oil features, and due to the ability of detecting significant similarities and differences in consumer responses. Moreover, with the introduction of respondents’ social, demographic, and financial characteristics, CUB models allow the measurement of the influence that the consumers’ profile has upon the attributes of olive oil authenticity. The results showed that consumers attached great importance to taste, acidity, country and region of origin, olive variety, color, organic production, and regional certification in the evaluation of olive oil authenticity. In addition, secondary school graduates tend to use taste and olive variety, also indicating confidence in the authenticity of organic olive oil.     

Estimation of Consumers’ Willingness to Pay for Geographic Indications Bananas Using Conjoint Analysis

This study uses conjoint analysis to analyze consumers’ preferences for geographic indications (GI) bananas by examining the effects of production methods (inorganic, organic, certified organic, and natural), quality attributes (taste, perishability, medicinal, and nutritional), and price premiums (prices of GI bananas relative to prices of other bananas). Consumers were surveyed for demographic, economic, and taste and preference characteristics. The results show that consumers prefer GI bananas for their medicinal properties, natural production method, and lower price premium.     

The influence of African swine fever information on consumers’ preference of pork attributes and pork purchase

This paper uses a randomized survey instrument to study the impact of African Swine Fever (ASF) information on Chinese consumers’ preference for pork attributes and purchases during the recent peak of the ASF pandemic in 2019. We study consumers’ preference for pork attributes including brand, meat texture and taste, quality safety assurance, and traceability under different information treatments. Results show that the willingness to pay (WTP) for quality safety assurance is the highest, followed by brands and traceability systems, and the WTP is lowest for good taste. We show that providing detailed ASF information substantially changes consumer preference by altering the relative importance of pork attributes and price sensitivity, which enables consumers to focus more on safety-related attributes while paying less attention to price and taste attributes. Furthermore, we find that a higher belief in the future of ASF occurrence reduces the frequency of purchases marginally but does not significantly influence for amount per purchase and the total purchase amount.     

Valuing Quality Attributes and Country of Origin in the Korean Beef Market

For beef exporters, one of the important questions in the Korean beef market is why Korean consumers are willing to pay almost three times more for domestic Korean beef than they pay for imported beef. To answer this question, we surveyed 1,000 shoppers in Seoul, Korea, and conducted a conjoint analysis on consumers’ willingness to pay (WTP) for country equity of domestic vs. imported beef and quality attributes of marbling, freshness, genetically modified organism (GMO)‐free feed ingredients and antibiotic‐free production. Among all factors contributing to the price differentials, the most important factor seems to be the country of origin followed by the use of GMO feeds and antibiotics in beef production, marbling grade and freshness. This study finds that Korean consumers value origins of imported beef approximately $14/lb less than the Korean origin. Korean consumers’ valuation of beef quality and country of origin differs by some demographic groups: older vs. younger generations, homemakers vs. non‐homemakers and consumers who prefer to purchase packaged beef vs. consumers who prefer to purchase butcher shop beef. Our empirical findings suggest that the top priority for beef exporters who wish to increase sales and value of their beef in the Korean market must be to counter Korean consumers’ strong ethnocentrism by improving the value of their country of origin.     

The Effects of Extrinsic Cues on Olive Oil Price in Brazil

Over the past two decades, world olive oil consumption registered an impressive growth. Although olive oil consumption remains concentrated in the main producer countries surrounding the Mediterranean Sea (“traditional” markets), it is also growing rapidly in many other countries all over the world, where olive oil is still largely perceived as a novelty food (“nontraditional” markets). This study focuses on the Brazilian market of olive oil, which is one of the most important nontraditional markets in terms of both its dimension and growth rates. A hedonic price model has been used to evaluate whether, and to what extent, extrinsic cues impact on the retail price of olive oil. Data were collected via direct observation of several e-shops where Brazilian consumers could purchase olive oil. Results show that the retail price of olive oil is highly influenced by extrinsic cues such as branding, labeling, and packaging.     

Consumer preferences for domestic and organically labelled vegetables in Sweden

The aim of our research is to examine Swedish consumers' perception and preferences of domestic vegetables compared to on the one hand imported and on the other hand organically grown vegetables. The paper draws from two consumer studies. The first study is a text analysis of consumers' associations to the four concepts Swedish, imported, organic and conventional vegetables as well as a conjoint analysis of the relative importance of the same four characteristics in the case of carrots. The second study is a taste experiment on tomatoes from the same Swedish grower labelled in three different ways, as Swedish, Dutch or organic. The conjoint analysis indicates that Swedish origin is considered more important than organic production methods. The text analysis shows that Swedish is associated with positive values, for instance, high quality, while imports have a more negative image. Organic is associated with characteristics such as being non-toxic, good quality and expensive while conventional is associated with poison, being good enough and traditional. The preference for Swedish vegetables is supported by the taste study. Tomatoes that were labelled as Swedish or organic were perceived as tastier than tomatoes labelled as Dutch. Thus, the experience of taste seems to be affected by the labelling. The conclusion is that to many Swedish consumers “Swedish is good enough” as a quality criterion. However, the research situation differs from a real shopping environment, where consumers make choices between bundles of different attributes, not only provenance and production method. Moreover, in a real shopping situation supermarkets promote their own private brands, regardless of origin, thus make origin less accentuated.     

PDO Olive Oil Products: A Powerful Tool for Farmers and Rural Areas

Abstract

Nowadays, consumers’ quality awareness and health consciousness drive the agri-food market towards a consumer-response food market. As a result, many producers and firms in the Euro-Mediterranean countries have opted for several quality and origin assurance schemes. Among them, a prevalent role is played by the Protected Designation of Origin (PDO) certification that constitutes a successful differentiation tool for agricultural products, and it is also widely used by Euro-Mediterranean olive oil producers due to effective contribution in promoting high-quality olive oil. After going through previous studies of PDO olive oil, this review paper investigates the general aspects and prospects of PDO olive oil products and EU relevant regulations, highlighting the socio-economic dimensions and impacts upon producers, consumers, and rural areas, and determining the gap between literature and practice with regards to PDO’s implementation and the expected benefits. Finally, the paper concludes with the main points and recommendations for further research.     

Estimations of Consumer Demand for Local Beef

In this article, we explore the role of local production as an attribute in consumer preferences for beef and attempt to quantify consumers’ purchasing behavior with respect to changes in price. We develop and employ a survey instrument using a randomly selected sample of consumers in Eastern Washington and Northern Idaho. Using data from the survey, we use conjoint analysis to estimate own-price elasticities of demand for beef produced using different production technologies and at different distances from purchase site to place of origin. Results show that consumer demand for beef and beef products is highly elastic, and the implications of this for producers and marketers are explored.     

Consumers' Willingness to Pay for Locally Produced Ground Beef: A Case Study of the Rural Northern Great Plains

This study examined consumers’ preferences and willingness to pay (WTP) for locally produced ground beef with an emphasis on the impacts of product attributes and the heterogeneity caused by rural consumers’ characteristics. We applied the choice-based conjoint technique to analyze data collected from a typical rural town in the Northern Great Plains. The results indicate that location associated product brand differences and leanness were dominant components affecting consumers’ WTP. The premium of locally produced ground beef for consumers with a close tie to local production is $0.48/lb. Cut difference, grass-fed, and organic were trivial factors in determining consumers’ WTP.     

Consumers' Perception of Food Product Quality in Tunisia

Abstract

This paper investigates consumers' perception of food quality in Tunisia. In fact, the development of quality standards is driven by government regulations and mostly in response to export markets regulations. The role of consumers in this process is quite missing. This paper first highlights the current food safety and quality programs undertaken by the Tunisian government. Second, we use a sample of 150 consumers chosen at random at two of the largest hypermarkets in Tunisia to analyze consumers' behavior regarding quality. The paper shows strong concerns about hygiene among other quality attributes and strong awareness about quality and quality assurance schemes in general. Consumers are also motivated by habits of consuming home made products for hygiene and taste reasons. If appropriate quality systems were implemented to assure consumers about such attributes this would boost up demand for quality products.     

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.     

Assessing Consumer and Producer Preferences for Animal Welfare Using a Common Elicitation Format

We assess pig farmers’ willingness‐to‐accept (WTA) higher farm animal welfare (FAW) standards and consumers’ willingness‐to‐pay (WTP) for thus enhanced standards. The analysis is based on discrete choice experiments with nearly identical choice sets for both farmers (N=140) and consumers (N=554). Based on preference estimates from a random parameter logit (RPL) model, supply and demand curves for high‐welfare pork in Germany are estimated and market equilibria are derived for alternative levels of FAW. We find that estimates of consumer WTP are significantly positive for all FAW attributes: consumers value more surface space per pig, more bedding and manipulable material, less surgical interventions and shorter transportation times. In contrast, our model revealed significant producer WTA estimates only for surface area per pig and the amount of bedding material on offer, but not for the other FAW attributes. Farmers who expect to continue farming and engage in direct marketing are more likely to adopt higher FAW standards. Male consumers and those who find price more important than brand, origin or taste are less likely to buy high‐welfare pork, as are consumers who never purchase organic meat products. Market simulations for high‐welfare pork indicate increasing divergence between demand and supply with rising FAW standards. We estimate a market share of 44.6% for pork produced in compliance with an entry‐level FAW programme with standards only slightly above the legal minimum. Programmes with more demanding standards are estimated to gain much smaller market shares.     

Consumer Quality Perception in Traditional Food: Parmigiano Reggiano Cheese

Abstract

The paper aims to classify the quality cues and attributes of grated Parmigiano Reggiano cheese, an Italian traditional food cheese, exploring if they affect consumers’ quality perceptions and expectations. Analysis is based on a questionnaire administered in hypermarkets where grated Parmigiano Reggiano is sold. A factor analysis, using varimax rotation, and a cluster analysis, were performed, using the Stata 12 software package. The clusters used were: geographical origin and packaging (cluster 1); price, brand and quality certification (cluster 2); all sensory attributes (cluster 3); and a combination of sensory attributes with price, brand, and quality certification (cluster 4). This is the first study to examine the quality cues and attributes affecting quality perception and expectations of cheese for grated Parmigiano Reggiano from a consumer perspective. It is also the first to classify cheese attributes following a quality approach, encompassing previously studied sensory and other attributes.     

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.     

Effects of perceived product quality and Lifestyles of Health and Sustainability (LOHAS) on consumer price preferences for children's furniture in China

The effects of perceived product quality and orientation toward Lifestyles of Health and Sustainability (LOHAS) on consumer price preferences were studied with the use of survey data of the children's furniture market in two metropolitan cities of China: Shanghai and Shenzhen. Based on the results from a factor analysis and logistic regression, consumers’ perceived product quality of children's furniture was identified as a four-dimensional construct: ‘supplier attributes’, ‘extended product attributes’, ‘basic product attributes’ and ‘environmental quality attributes’. Consumer price preferences were discovered to be negatively influenced by ‘basic product attributes’, but positively influenced by consumer orientation towards LOHAS, gender and education level. In conclusion, China's children's furniture market presents a high-end niche segment with growth potential for both furniture producers and wood material suppliers.     

Food Values

Because of the potential malleability of stated and revealed preferences for new food technologies and attributes, this research sought to determine consumers' food value systems by utilizing recent advances in best-worst scaling. Based on previous literature related to human values and food preferences, a list of eleven food values was compiled. Results reveal that on average the values of safety, nutrition, taste, and price were among the most important to consumers, whereas the values of fairness, tradition, and origin were among the least important; however, there was significant heterogeneity in the relative importance placed on food values. Results indicate that food values are significantly related to consumers' stated and revealed preferences for organic food.     

Customers’ Preferences for Different Processed Tomato Categories in Food Service

Hypothetical discrete choice experiments were conducted to elicit food-service professionals’ preferences and willingness-to-pay for different attributes of processed tomatoes. A sample of 110 food-service professionals were surveyed in Italy, Russia, Eastern Europe, and South Korea in 2012. Data were analyzed by using multinomial logit and random parameter logit models. Results suggest that food-service professionals preferred peeled tomatoes to chopped pulp, tomato purée, and tomato paste. However, their preferences were heterogeneous. They would pay a premium price for products labeled with Italian origin. Types of cuisine sold by practitioners, numbers of points of sale, and nationalities also influence practitioners’ WTP. Factors affecting their purchasing decision were freshness of product, followed by convenience, cooking time, price, origin of product, and brand. This study shows that the research method is suitable for evaluating the preferences of food-service professionals. The preferences of industry operators resemble those of consumers.     

The impact of customer ratings on consumer choice of fresh produce: A stated preference experiment approach

The importance of customer ratings or reviews in online shopping has been recognized in the previous literature; however, few have studied how online customer rating scores affect consumers’ fresh produce purchases and its importance relative to other fresh produce attributes. The quality of fresh produce demonstrates high uncertainty and variation; therefore, the impact of user-generated content such as customer rating scores on the choice of fresh produce may be more complex than on other product categories. Moreover, previous studies on customer ratings have not examined the price premium that retailers can obtain based on better ratings of fresh produce. Using a stated preference approach (i.e., choice experiment), this study measures the willingness to pay for a higher customer rating score and explores its relative importance to other popular fresh produce attributes (i.e., organic, place of origin, and shelf life). The results show that customer rating is the second most important attribute after the place of origin and is more important than production methods (e.g., organic and naturally grown) for fresh strawberry purchases. Also, rating scores demonstrate a diminishing marginal impact on consumer willingness to pay. Younger consumers and households with children are willing to pay more for fresh produce with high ratings than those with low ratings.     

Customer preferences for customized household furniture

In the context of market globalization, furniture manufacturers attempt to differentiate their products to attain competitive advantages. Mass customization is one strategy enabling such differentiation. This study measured, through a choice-based conjoint analysis, the value that US American consumers assign to the availability of customization when buying furniture. Roughly 50% of consumers’ product choice is driven by price, 20% by product customization, 20% by delivery time, and 10% by the time needed to customize the product. Thus, while there is a customer segment driven by price, there also is a segment, consisting mainly of females, that values product customization.     

A new market for an old food: the U.S. demand for olive oil

While U.S. consumption of olive oil has tripled over the past two decades, nearly all olive oil continues to be imported. Estimation of a demand system using monthly import data reveals that the income elasticity for virgin oils sourced from EU is above one, but demand for nonvirgin oils is income‐inelastic. The demand for olive oil as a single product is price‐inelastic. Differentiated by product characteristic and origin, olive oils are highly substitutable with each other but not with other vegetable oils. News about the health and culinary benefits of olive oil and the spread of Mediterranean diet contribute significantly to the rising demand.
