Consumer valuation of health attributes for soy-based food: A choice modeling approach

Given that soy foods possess health-promoting attributes that offer the promise of reducing heart-related chronic diseases, this article employs choice experiments to estimate marginal willingness to pay (WTP) for soy attributes including taste, contents of soy protein, and health claim. Random parameter logit (RPL) models were estimated in consideration of potential heterogeneity across individuals in their preferences for soy food. Standard deviation parameters in the RPL models are highly significant, indicating that individuals have widely varying preferences for soy-based food products. Results suggest that, while taste is the dominating attribute that drives consumers’ WTP for soy food products, consumers do respond to the information provided in the health claim. Yet, consumers do not seem to be recognizing soy protein as the link to health benefits of soy foods.     

The demand for organic foods in the South of Italy: A discrete choice model

This paper analyses organic food consumer’s demand that can help advising on implementing organic food policies at European level or, for a particular European country. In particular, it investigates the main factors explaining organic food demand in the South of Italy. Following the Lancaster consumer’s demand theory we assume that consumer’s utility depends on product characteristics instead of the product itself. Thus, consumers will choose the product (organic versus conventional) that possesses the combination of attributes that maximises its utility. Consumer’s choice for organic foods is analysed within the random utility discrete choice model and a bivariate probit model has been specified. The data were collected through a questionnaire conducted in the Italian region of Campania (Naples) in 2003. Findings indicate that economic factors are still factors limiting the growth of organic demand in Europe. Moreover, the consumers’ perceived benefits of organic food (environmental and health) are factors promoting organic food demand. In addition, greater information on organic food products is crucial to expand its demand in the South of Italy because this information will increase the consumer’s organic knowledge. Then, higher organic knowledge will increase the probability to buy organic foods and, to a larger extent, the level of consumption among existing consumers.     

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.     

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.     

Consumers’ response to the EU Quality policy allowing for heterogeneous preferences

Using dry-cured ham as an anchor product, consumers’ preferences for EU Quality Certification schemes, region of origin and price have been investigated with conjoint analysis. In order to achieve this aim, a mixed rank-ordered logit which allows for the investigation of heterogeneous preferences and their sources has been estimated. In particular, we have analysed to what extent consumers’ socio-demographic traits affect their price-sensitiveness and whether consumers’ sensory (hedonic) valuations and attitudes towards ham with a Protected Designation of Origin (PDO) affect the preferences for specific attributes. Results show that consumers with a low-medium age and income are more price sensitive. Consumers more inclined sensorially towards the regional specialty (with or without PDO) are more likely to purchase this product, and consumers with a more favourable attitude towards PDO ham are also more prone to purchase cured ham with quality certification. Findings also suggest that although the PDO scheme attracts a segment of consumers, the origin by itself is still a more powerful signal of quality, and more specifically the region of origin.     

A choice experiment model for beef: What US consumer responses tell us about relative preferences for food safety,country-of-origin labeling and traceability

Several food safety issues have prompted questions regarding the role of country-of-origin labeling, traceability, and food safety inspections in consumers’ perceptions of food safety and quality. The importance of origin-labeling and traceability have been discussed in the EU for some time. North American cases of mad cow disease have led to increased discussions of these topics in the US, however, relatively little research has been conducted to examine the value US consumers place on these attributes. Choice experiments were used to analyze US consumers’ relative preferences and willingness-to-pay for these meat attributes in labeled ribeye beef steaks. Relatively speaking, consumers value certification of USDA food safety inspection more than any of the other choice set attributes, including country-of-origin labeling, traceability and tenderness. As a result, indication of origin may only become a signal of enhanced quality if the source-of-origin is associated with higher food safety or quality.     

Fish: Friend or foe? Food policy and subpopulation warnings for consumers

Fish is a healthy food that provides valuable nutrients for heart health and cognitive development. However, for some subpopulations, consuming fish containing higher levels of methylmercury may pose a health risk. This research seeks to identify the impact of including a seafood warning disclosure in the advertisement of a can of tuna fish on consumers’ purchasing behaviors. An experimental survey is employed to examine the resulting impact for two segments of the population – those considered at risk for methylmercury overexposure and all others. Findings indicate the use of warning disclosures increases respondents’ negative product perceptions without significantly altering positive product perceptions. Attention to the warning is short-lived and does not significantly impact perceived healthful levels of consumption. Modeling purchase behavior using a random utility choice framework indicates that the inclusion of a warning in an advertisement of a can of tuna fish has no adverse affect on purchase behaviors for the population not at-risk and may, in certain cases, serve to decrease tuna purchase likelihood for “at-risk” respondents. Communicating advisory statements on healthy products, such as fish, creates a public health challenge; message pre-testing is imperative.     

Genetically modified food labeling: The impacts of message and messenger on consumer perceptions of labels and products

We analyze responses to a survey designed to elicit consumer reaction to various approaches to labeling genetically modified (GM) foods. Consumers were shown sample labels that differed with respect to claims concerning the presence and potential effects of GM ingredients and the agency that certified these claims. A sample of 1898 US consumers rated 3681 labels with regard to the credibility and adequacy of the information content, with regard to perceived health and environmental impacts of the product and with regard to purchase intent. Simple claims that a product contains GM ingredients are viewed as most credible while simple claims of no GM content are viewed as most adequate. Label claims certified by the US Food and Drug Administration (FDA) are, in general, viewed as most credible and adequate and products with FDA certified claims are perceived to have fewer long-term health problems. Several practical policy implications of the results are discussed, including how different label messages may impact consumer reactions in markets involving GM products.     

Consumers’ willingness to pay for eco-friendly apples under different labels: Evidences from a lab experiment

An experiment was conducted in France to evaluate the impact of health and environmental information on consumers’ choices between conventional and organic apples. Results show that additional and precise messages about both pesticides use and pesticides residues significantly impact consumers’ choices between both products. The experiment also studied the effect of a new label signaling apples that only use few pesticides compared to conventional apples. With elicited willingness-to-pay, we show that the introduction of this new label increases the average participants’ surplus whatever the information context for participants, because of a higher quality compared to conventional apples and a lower price compared to organic products. In order to complement this label, a minimum-quality standard imposing the use of few pesticides is socially optimal when initial participants’ knowledge is limited.     

Functional food,uncertainty and consumers’ choices: A lab experiment with enriched yoghurts for lowering cholesterol

A lab experiment was conducted in France to evaluate the impact of health information on consumers’ choices for functional food. Successive messages revealing benefits and uncertainties of consuming yoghurts with added plant sterols for reducing cholesterol were delivered. Results show a significant and positive influence of the message linked to the cholesterol reduction on willingness to pay, even for participants without cholesterol. However participants expressed little interest in information about potential risks and scientific uncertainties, since their impacts on willingness to pay are not always statistically significant. An econometric estimation shows a significant link between the change in willingness to pay and the perception by participants regarding the scientific validity linked to the sterols.     

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 character of demand in mature organic food markets: Great Britain and Denmark compared

We investigate the organic food market in two selected European countries, Great Britain and Denmark, identifying main differences and similarities. We focus particularly on consumer perceptions and priorities, labelling schemes, and sales channels as a basis for assessing market stability and prospects for future growth. We employ a unique set of household panel data that includes information on stated values and concerns as well as registered purchasing behaviour. Most organic food on both markets is produced and processed by large-scale industrialised units and distributed through mainstream sales channels, consumer confidence being sustained at present by organic labelling schemes that appear to function well. However, a parallel market, based on the supply of goods through various direct sales channels to heavy users, prevails. We find that organic food purchase decisions are primarily motivated by ‘private good’ attributes such as freshness, taste and health benefits, attributes that may be perceived as being compatible with modern production and sales structure. Mature markets for organic foods nevertheless appear to be vulnerable to consumer dissatisfaction, particularly among heavy users of organic food products.     

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.     

Service inside: The impact of ingredient service branding on quality perceptions and behavioral intentions

Extant literature on ingredient branding is directed at tangible products but does not account for the role of services as ingredients. For B2B suppliers, however, service is emerging as the dominant route to achieving competitive advantage. The purpose of this research is to investigate how ingredient service brands impact customer preferences on B2B markets. We specifically assess how ingredients might impact industrial buyers' quality perceptions of the end product. By conducting a within-subjects scenario-based experiment among industrial buyers, we find a positive effect of the presence of an ingredient service brand on buyers' perception of the end product's service quality, whether the host brand is of higher or lower quality. The effect is stronger when the quality of the host brand is lower. Furthermore, results indicate that the host brand generally has a stronger impact on the quality evaluation of the end product meaning that an ingredient service brand cannot fully compensate for a lower-quality host brand. For managers, our findings indicate that ingredient service brands provide a cue to product quality of the end product, indirectly improving purchase intentions. As a result, branded service ingredients offer host service brands as well as ingredient service brands a potentially powerful strategy for improving competitive position in B2B markets.     

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.     

Saving two in a billion:: quantifying the trade effect of European food safety standards on African exports

A growing concern over health risks associated with food products has prompted close examination of sanitary and phytosanitary standards in industrialized countries. This paper quantifies the impact of a new harmonized aflatoxin standard set by the EU on food exports from Africa. We employ a gravity model to estimate the impact of changes in differing levels of protection based on the EU standard, in contrast to those suggested by international standards. The analysis is based on trade and regulatory survey data for 15 European countries and nine African countries between 1989 and 1998. Our results suggest that the implementation of the new aflatoxin standard in the EU will have a negative impact on African exports of cereals, dried fruits and nuts to Europe. The new EU standard, which would reduce health risk by approximately 1.4 deaths per billion a year, will decrease these African exports by 64% or US$ 670 million, in contrast to regulation set through an international standard.     

The Role of Objective In Vivo Testing in the Product Development Process

New products managers are continually confronted by the challenge of coordinating flows of complex information during the product development process. Among the issues faced are unique problems in relating technical design of product attributes to customers' reactions, leading to an improvement of the product's benefits. Ronald Drozdenko and Sidney Weinstein describe a variety of tests which help to assess customers' reactions to products, thus providing information to improve the design or to substantiate advertising claims. The term "objective in vivo" is given to a category of tests which is employed to quantify consumers' evaluation of specific product attributes under controlled, simulated use conditions. This helps to bridge the gap between tests which are designed to measure the physical or functional aspects of new products and tests which measure the consumers' self-reported, subjective reactions. A test categorization model, illustrative case studies, and test selection criteria are presented.     

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.     

Food health claims – What consumers understand

Issues pertaining to consumer understanding of food health claims are complex and difficult to disentangle because there is a surprising lack of multidisciplinary research aimed at evaluating how consumers are influenced by factors impacting on the evaluation process. In the EU, current legislation is designed to protect consumers from misleading and false claims but there is much debate about the concept of the ‘average consumer’ referred to in the legislation.     

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.
