Willingness-to-pay for natural,organic, and conventional foods: The effects of information and meaningful labels

Vague food labels and distorted product claims have persisted in the “natural” food industry, while organic claims can be certified by the U.S. Department of Agriculture (USDA). Using experimental methods and a sample of randomly selected subjects, we test food label and information treatment effects on subjects' willingness-to-pay (WTP) for organic, “natural,” and conventional foods. Random nth-price auctions are used to elicit WTP after subjects received one of five randomly assigned information treatments. We find large information effects, including asymmetric cross-market effects for natural and organic foods. Perhaps surprising is that organic premiums increase in response to subjects seeing the “natural” foods industry's perspective on its products. Demographics effects are also important. The results have practical implications for natural and organic food marketing and valuing products where there are vague claims about their attributes.     

Impact of health-related claims on the perception of other product attributes

New EU legislation (EU Regulation 1924/2006) will allow a number of nutrition and health claims in food products. The objective of this research was to study how health claims affect consumers’ perception of other product attributes. A survey with a total of 4612 respondents from the Nordic countries explored consumers’ perceptions of attractiveness, healthiness, naturalness, tastiness and ability to reduce risk of disease by comparing ratings of products with and without health claims. Used claims varied in their benefit, active ingredient, claim structure and framing. The results showed that health claims had a moderate but mostly negative impact on the perception of other product attributes; the most significant impact was decrease in perceived naturalness. Consumers could also interpret the benefits in claims as intended. The wording of the claim had only small impact on the perception of the products, whereas earlier market presence of the ingredient had a large impact: differences among the Nordic countries reflected the previous exposure to health claims. The findings from this study suggest that consumers do not imply other health benefits from health claims and the health claim per se is not likely to cause any unrealistic positive inferences in perceived product quality.     

Front-label health claims: when less is more

Growing global attention has been directed toward labeling the ingredients, processing methods, and health claims of food. Accompanying this attention is an interest in how consumers process or understand the information on such labels. This article examines how the length of a front-label claim influences the nutritional beliefs and evaluation of a product when used in combination with complete back-label information. The results indicate that the presence of a shorter health claim on the front of the package (in combination with a more complete claim on the back) leads a person to generate more attribute-specific thoughts about the product and fewer general evaluative thoughts compared to longer health claims. These shorter health claims also led to more favorable beliefs about the product and to a more positive image of the product. This article concludes with a discussion of the implications of the findings for policy makers, consumers and researchers.     

Does nutrition information on food products lead to healthier food choices?

This paper examines the link between nutrition label use and consumers’ healthier food choices. Label use is considered for the two main types of labels currently found on food products; nutrition facts panels and nutrition/health claims. This link is tested using a three-equation multivariate probit model. Data were obtained from an ad hoc survey conducted in two medium-sized Spanish cities. The results indicate that the use of nutrition information by consumers, whether this involves the fact panel or the claim labels, does influence consumer choice of healthier food products to the same extent, although different types of consumers use the various types of labels considered.     

The evolution of language complexity in qualified health claims

In the US, the Food and Drug Administration (FDA) has oversight for qualified health claims (QHCs). These claims emerged as the result of a legal dispute about commercial speech rights on dietary supplements and food products. The initial court ruling allowed manufacturers to include diet–disease information on packaging, when supporting evidence does not meet the traditional threshold of Significant Scientific Agreement. QHCs communicate about a potential health benefit of the consumption of a food or supplement, and due to their nature, are required to specify the balance of evidence behind the diet–disease relationships. As a result, the language contained in QHCs is complex, making them difficult for consumers to understand. The language has been further complicated by a continuing series of court challenges about how scientific evidence is described in QHCs. To understand the evolution of QHC language, we review the progression of court rulings surrounding qualified health claims and subsequent regulations by the FDA. This analysis provides a case study of the challenging task of effective science communication within a dynamic food litigation and policy environment.     

Demand for ecolabeled seafood in the Japanese market: A conjoint analysis of the impact of information and interaction with other labels

The use of seafood ecolabels is expanding in the world marketplace, but so are labels indicating other product attributes, such as country of origin and wild vs. farmed. The interactive effects of these labels and attributes in evaluating consumers’ preferences for ecolabeled seafood are relatively unexplored. In this paper we investigate (1) the direct and interactive effects of seafood ecolabels with other common fish labels, and (2) how consumers’ perceptions about the state of marine stocks and the valuation of ecolabels may be affected by different information. We find moderate interactive effects between ecolabels and country of origin labels, whereas the valuation for seafood ecolabels is fairly high. In terms of information, we find that consumers’ perceptions about fish stock levels changed (negatively) after receiving information on declining stock levels, and more sensationalized information led to increased change. However, valuation for a seafood ecolabel increases only when the information was perceived positively (credible/interesting); whereas exaggerated information (which was also perceived less credible) had insignificant effects on WTP.     

Health claims and consumers’ behavioral intentions: The case of soy-based food

This research evaluates the impact of two soy-specific health claims (highlighting FDA approval along with scientific results and simply describing scientific results) on stated behavioral intentions toward soy-based food using a survey administered by Ipsos-Observer to a nationally representative web panel in the summer of 2007. Our research design randomly assigned respondents to a health claim. Three ordered probit models (non-soy users; infrequent soy users; regular soy users) show that non-soy users and infrequent soy users who were exposed to either FDA health claim or general health claim are significantly more likely to eat soy-based food products. FDA or general health claim, however, did not change the behavioral intentions of regular soy users. These results suggest that soy consumption status moderates the impacts of health claims on behavioral intentions. However, the impact of FDA health claim did not differ from that of general health claim, indicating that the word ‘FDA’ did not add any additional information to consumers beyond the general health claim.     

Do firms leverage the FDA nutrient label rounding rules to generate favorable nutrition fact panels or health claims?

The increasing incidence of nutrition related health concerns has made food labeling an important policy issue. Previous work suggests the importance of communicating nutrition information to consumers through product packaging. This paper investigates the role of labeling guidelines, which allow the rounding of calorie and nutrient levels on nutrition fact panels and affects front of package claims. We examine ready-to-eat cereal products as a bundle of nutrient attributes, and estimate the likelihood and magnitude of the rounding of specific nutrients and calories. We find systematic rounding, both up and down, of several nutrients, which affects allowable health claims and may influence consumer product choice and health outcomes.     

The impact of mandatory trans fat labeling on product mix and consumer choice: A longitudinal analysis of the U.S. Market for margarine and spreads

The impact of changes in food labeling policy on food consumption depends on how market participants—both firms and consumers—react to the changes across all products in the market. We investigate how both responded to the U.S. Food and Drug Administration’s 2006 rule mandating that the quantity of trans fat in food products be separately labeled on the mandatory Nutrition Facts Panel across an entire differentiated product category. Using a longitudinal data set tracking both product offerings and consumer purchases in the market for margarine and spreads for over a decade, we analyze how product mix and consumer purchase behaviors were influenced by the new regulatory requirement. We find that the number of products bearing voluntary “trans fat free” labels increased after the labeling regulation was implemented. However, a large number of the newly introduced products exited the market within five years. As a result, the FDA’s 2006 rule had a stronger short-run than long-run effect on product offerings. Even after the introduction of additional “trans fat free” labeled products, such products remained only a small percentage of margarine and spreads product offerings, increasing from a pre-regulation level of 2.3% of the market to a peak of 6.5% in 2007 before dropping to 3.1% by 2011. In addition to firm response, we examine demand-side reactions to the 2006 rule and find that consumers significantly increased their expenditures on “trans fat free” labeled products soon after the labeling changes were implemented, increasing from about 1.2% of the market in 2001 to a peak of 5.9% in 2007, before returning to 1.8% in 2011. We further explore variations in responses across different demographic characteristics. Although long-run effects are small, the market for “trans fat free” labeled margarine and spreads settled into a new equilibrium with a somewhat higher level of products in the market than prior to the 2006 rule taking effect and a somewhat higher share of expenditures in the category. Overall, our category-wide analysis of both firm and consumer behavior indicates that the effects of the labeling policy change were smaller in the longer run in this market than would be indicated by an analysis of only new product introductions in response to the policy change.     

European consumer preferences for beef with nutrition and health claims: A multi-country investigation using discrete choice experiments

The European Union (EU) nutrition labelling policy aims to facilitate consumers’ food choice, stimulate innovation and facilitate the circulation of foods bearing claims across countries. However, the beef industry has not fully taken advantage of utilizing nutrition and health claims based on the EU nutrition labelling policy to differentiate beef products in the market. This study investigates consumer preferences for nutrition and health claims on lean beef steak. Two choice experiments were conducted among 2400 beef consumers in four EU countries (Belgium, France, the Netherlands, United and United Kingdom). Multinomial logit and error component models were estimated. Our results generally suggest that consumer valuation of nutritional and health claims varies across countries. In Belgium, the Netherlands and France, nutrition and health claims on saturated fat yielded higher utilities than claims on protein and/or iron, while the opposite was found among consumers in the UK. The results imply that marketing opportunities related to nutrition and health claims on beef are promising, but that different nutritional marketing strategies are necessary within different countries.     

The impact of expiration dates labels on hedonic markets for perishable products

This study draws inferences from a pre-registered field experiment to investigate how expiration dates impact consumer preferences for food products with different ages. Based on a power analysis, we recruited 373 adult participants for the experiment. The results demonstrate that expiration dates largely influenced the perceived freshness of a food product as they seem to indicate a quality standard. When no explicit expiration date was present, consumers believed that the product’s quality decreased monotonically as time passed. However, in the presence of an expiration-date label, consumers initially perceived the product as more acceptable, but then that perception changed quickly after the date of expiration to levels more consistent with what they would perceive if the expiration date was not present. These results support policies that label expiration dates for consumers, as these labels benefit consumers, producers, and the public, especially for times prior to the expiration date. These results also suggest that it is important to craft policy and market strategies for products that are past the expiration date, but are still safe to consume. Policies that set the expiration dates to the time where the taste quality begins to worsen would likely benefit both consumers and producers, while policies that set the expiration dates to the time where the food is no longer safe probably improve the public outcomes as it minimizes food waste.     

Do consumers perceive benefits from the implementation of a EU mandatory nutritional labelling program?

This paper examines consumers’ knowledge about nutritional labels (i.e., nutritional panel), use of nutritional labels, and perceived benefits from a mandatory nutritional labeling program. Using data from a pilot study conducted in a Spanish city and a three-equation multivariate probit model, our results suggest that individuals who suffer some health problems related to food intake are more knowledgeable about nutritional labels. Further, those who are more knowledgeable about nutritional labels are more likely to use nutritional labels, and nutritional label users are more likely to consider mandatory nutritional labeling as beneficial. Perceived usefulness of the information provided by nutritional labels as well as the amount of presented information affect consumer perceptions about whether or not mandatory nutritional labeling would be beneficial.     

Impact of genetic modification on country image of imported food products in European markets: Perceptions of channel members

Risk to the image of food exporting countries in foreign markets for food products has been advanced as a reason for them to ban commercial release of genetically modified (GM) crops. The aim of this paper is to explore the reality and intensity of such a risk. In-depth interviews have been conducted with key distributors in the European food sector to ascertain factors that they consider important in determining reputation of exporting countries, and to ascertain whether GM impacts on such reputations. Highly negative consumer sentiment towards GM in Europe seems likely to continue to influence food industry buyers against importing GM food. However, no evidence was found that presence of GM crops in a country causes negative perception of non-GM food imported from that country. Provided adequate steps are taken to avoid accidental contamination of conventional crops, producer countries do not appear at great risk of damaging their overall country image for food products if GM technology is introduced.     

Sustainability labels on food products: Consumer motivation,understanding and use

This study investigates the relationship between consumer motivation, understanding and use of sustainability labels on food products (both environmental and ethical labels), which are increasingly appearing on food products. Data was collected by means of an online survey implemented in the UK, France, Germany, Spain, Sweden, and Poland, with a total sample size of 4408 respondents. Respondents expressed medium high to high levels of concern with sustainability issues at the general level, but lower levels of concern in the context of concrete food product choices. Understanding of the concept of sustainability was limited, but understanding of four selected labels (Fair Trade, Rainforest Alliance, Carbon Footprint, and Animal Welfare) was better, as some of them seem to be self-explanatory. The results indicated a low level of use, no matter whether use was measured as self-reported use of different types of information available on food labels or as use inferred from the results of a choice-based conjoint analysis. Hierarchical regression indicated that use is related to both motivation and understanding, and that both motivation, understanding and use are affected by demographic characteristics, human values as measured by the Schwartz value domains, and country differences. The results imply that sustainability labels currently do not play a major role in consumers’ food choices, and future use of these labels will depend on the extent to which consumers’ general concern about sustainability can be turned into actual behaviour.     

Consumer willingness to pay for redundant food labels

Previous studies, as well as market sales data, show some consumers are willing to pay a premium for redundant or superfluous food labels that carry no additional information for the informed consumer. Some advocacy groups have argued that the use of such redundant labels is misleading or unethical. To determine whether premiums for redundant labels stem from misunderstanding or other factors, this study seeks to determine whether greater knowledge of the claims - in the form of expertise in food production and scientific literacy - decreases willingness to pay for redundant labels. We also explore whether de-biasing information influences consumers’ valuations of redundant labels. An online survey of 1122 U.S. consumers elicited preferences for three redundantly labeled products: non-GMO sea salt, gluten-free orange juice, and no-hormone-added chicken breast. Respondents with farm experience report lower premiums for non-GMO salt and no-hormone-added chicken. Those with higher scientific literacy state lower premiums for gluten-free orange juice. However, after providing information about the redundancy of the claims, less than half of respondents who were initially willing to pay extra for the label are convinced otherwise. Over 30% of respondents counter-intuitively increase their premiums, behavior that is associated with less a priori scientific knowledge. The likelihood of “overpricing” redundant labels is associated with willingness-to-pay premiums for organic food, suggesting at least some of the premium for organic is a result of misinformation.     

Signaling Quality: An Examination of the Effects of Marketing‐ and Nonmarketing‐Controlled Signals on Perceptions of Automotive Brand Quality

When introducing new products to market, firms often leverage marketing signals in an effort to increase perceptions of product quality. While prior research mostly focuses on marketing‐controlled signals that firms can directly influence to affect consumer perceptions of product quality, the proliferation of nonmarketing‐controlled signals in the form of third‐party product reviews introduces a new layer of complexity to a consumer's inference process. Given the fact that propagation of marketing signals and third‐party reviews has made the marketplace more interactive, it is no longer diagnostic to analyze the impact of various quality signals on consumer perceptions, separately. The purpose of this study is twofold. There has been extant research on the individual effects of marketing‐controlled signals on quality perception, but research providing a simultaneous examination of multiple signals is scarce. The first purpose is to examine interaction effects between various marketing signals on consumer perceptions of quality. Firms may be able to control the communication strategy of internal signals (e.g., price, advertising), but third‐party signals are external to the firm, and hence are often perceived as being more credible and less biased than marketing signals. Despite the popularity of third‐party product reviews, there is scarce empirical research about how they impact perceptions in the presence of marketing‐controlled quality signals. Thus, the second purpose is to examine the interaction effects between marketing signals and independent third‐party reviews on perceived product quality. This study advances existing models of market signaling to account for the potential interactions between various types of quality signals. Hypotheses are tested using a longitudinal data set comprising all car brands that have existed in the U.S. automotive industry between 1990 and 2007. The automotive industry provides an ideal context for the analyses as quality is an indispensable yet not easily discernible attribute of cars. Furthermore, consumer perceptions of the quality of new vehicle introductions can have a profound effect on product performance. Data are compiled from various secondary sources, including Harris Interactive's Equitrend, Consumer Reports, and TNS Media Intelligence, among others. Econometric techniques are used to estimate the empirical model. Findings show that effects of quality signals are codependent such that third‐party quality ratings reduce the effectiveness of pricing and advertising, whereas they enhance the credibility of warranty signal. Furthermore, warranty positively interacts with price and advertising. It is also demonstrated that car sales in the previous period and the country of origin of the car brand significantly impact perceived quality. Overall, the research findings can help car manufacturers better understand how their initial product configurations and marketing strategies impact the perception of new vehicle introductions.     

How Today's Consumers Perceive Tomorrow's Smart Products*

This paper investigates consumer responses to new smart products. Due to the application of information technology, smart products are able to collect, process, and produce information and can be described as “thinking” for themselves. In this study, 184 consumers respond to smart products that are characterized by two different combinations of smartness dimensions. One group of products shows the smartness dimensions of autonomy, adaptability, and reactivity. Another group of smart products are multifunctional and able to cooperate with other products. Consumer responses to these smart products are measured in terms of the innovation attributes of relative advantage, compatibility, observability, complexity, and perceived risk. The study shows that products with higher levels of smartness are perceived to have both advantages and disadvantages. Higher levels of product smartness are mainly associated with higher levels of observability and perceived risk. The effects of product smartness on relative advantage, compatibility, and complexity vary across product smartness dimensions and across product categories. For example, higher levels of product autonomy are perceived as increasingly advantageous whereas a high level of multifunctionality is perceived disadvantageous. The paper discusses the advantages and pitfalls for each of the five product smartness dimensions and their implications for new product development and concludes with a discussion of the limitations of the study and suggestions for further research.     

Product Choice and the Importance of Aesthetic Design Given the Emotion‐laden Trade‐off between Sustainability and Functional Performance

This paper investigates the trade‐off decision that consumers face when choosing between a product that is perceived to be more sustainable (i.e., more socially and environmentally responsible) and another product that instead is perceived to offer superior functional performance. Prior research has demonstrated that consumers often believe that there is a trade‐off between sustainability and performance, and in some cases, this trade‐off may be real and not just perceived. The objectives of the current research are to understand the mediators and moderators of this trade‐off choice and to illustrate one specific way in which to use this understanding to promote the consumption of relatively more sustainable products despite a perceived performance trade‐off. Two separate studies were conducted. The first employed a student‐based sample, whereas the second employed a nationally representative online sample. In both studies, participants were presented with a choice between two consumer products. One product was depicted as having superior sustainability characteristics (and average functional performance), and the other product was depicted as having superior functional performance (and average sustainability characteristics). Participants were asked to imagine that they were leaning toward choosing one product over the other, and then rated the degree to which they were feeling a set of possible emotions. Following these ratings, participants chose one of the products. The results suggest that consumers presented with such a trade‐off will tend to choose the product with superior functional performance over the product with superior sustainability characteristics, due to feelings of distress, until a minimum threshold of functional performance is achieved. The current research also shows that choice given this trade‐off depends upon the degree to which consumers value sustainability that, in turn, is mediated by consumers’ feelings of confidence and guilt. Further, based on an understanding of the emotions mediating choice in this context, the authors demonstrate how the effective use of product aesthetic design can improve the relative choice likelihood of sustainable products. Specifically, the authors demonstrate that superior aesthetic design has a disproportionately positive effect on the choice likelihood of sustainability‐advantaged (versus performance‐advantaged) products due to the effect that superior aesthetic design has on overcoming the potential lack of confidence in sustainable products. These findings highlight the specific value of aesthetic product design in the context of marketing sustainable products and suggest that it is especially important for firms interested in marketing sustainable products to also develop market‐leading product aesthetic design capabilities.     

Chinese consumer demand for food safety attributes in milk products

Little is known about emerging demands for food safety among consumers in developing countries. This study presents results of an investigation of consumer awareness, willingness to pay, and price premiums for milk products manufactured using Hazard Analysis Critical Control Point (HACCP) management, a quality management system used to reduce food safety risks. Chinese food processors initially sought HACCP certification to access export markets, but now HACCP is rapidly being adopted for domestic products and HACCP logos have begun to appear on labels in China. A survey of Beijing consumers found that less than one in five respondents was aware of HACCP, and most who had heard of HACCP had learned about it within the previous year. After receiving information on HACCP nearly all respondents were willing to pay a modest price premium for HACCP-certified products. Products with HACCP labels in Beijing supermarkets sold at a price premium of about 5% over products without such labels, holding other product attributes constant. The results indicate that demand for food safety is emerging as an attribute demanded by Chinese consumers.     

The Impact of Word of Mouth Sources on the Perceived Usefulness of an Innovation

This paper examines the role of three indirect mechanisms linking word‐of‐mouth communication with one of the most important innovation attributes influencing the adoption decision: perceived usefulness. The authors hypothesize that word‐of‐mouth (WOM) communication impacts perceived usefulness by influencing potential adopter perceptions of the credibility of innovation information, the size of the adopter population, and the availability of complementary products. To test these hypotheses, the authors analyze the survey responses of over 550 potential adopters of e‐readers and smartphones. In both product samples, the perceived credibility of WOM information is positively related with perceived usefulness, which is positively related with purchase intent. Consistent with theoretical arguments regarding the importance of access to expert information sources, findings indicate that, relative to personal WOM, written and virtual WOM have stronger relationships with consumer perceptions of the credibility of innovation information. In addition, in both samples, perceived usefulness is positively related with the perceived availability of complementary products, which is positively related with both personal and written word‐of‐mouth. Finally, perceived usefulness has (1) a direct relationship with the perceived size of the local adopter population in the e‐reader sample and (2) an indirect relationship with the same variable that is mediated by the perceived availability of complementary products in both samples. In turn, the perceived size of the local adopter population is positively related with exposure to personal word‐of‐mouth.
