This paper investigates the reasons for the differences in customers' acceptance of service robots (CASR) in actual experience and credence service settings for the following two aspects: (1) different antecedents affecting CASR and (2) different customer perceptions of their own characteristics (role clarity and ability) and service robot characteristics (anthropomorphism and ability).

The data were collected using online surveys in an experience service setting (Hotel, N = 426) and a credence service setting (Hospital, N = 406). Differences in experience and credence service settings were examined using two statistical methods, namely, PLS-SEM to test the differences in antecedents affecting CASR and independent-samples t-tests to test the differences in customer perceptions of their own characteristics and service robot characteristics.

The results indicate that customers in an experience (vs credence) service setting have stronger positive attitudes toward and a greater intention to use service robots. Further, this paper finds there are two key reasons for the differences in CASR. The first is different antecedents. Perceived usefulness is positively influenced by the anthropomorphism of a service robot and customer ability in the experience service setting, but is influenced not in the credence service setting. Conversely, service robot autonomy positively relates to perceived ease of use in the credence service setting, but does not in the experience service setting. The second reason for CASR differences is different customer perceptions. Customers' ability and perceived ease of use are higher, while their perception of anthropomorphism of the service robot is lower in the experience (vs credence) service setting.

This study helps explain why there are differences in the CASR in different settings and presents two perspectives: (1) antecedents' affecting CASR and (2) customer perceptions of their own as well as service robot characteristics.

This paper aims to empirically investigate the role of product positioning in the launch of food and drink products using a large dataset of new product development by food companies in Australia (AU) and New Zealand (NZ). As such, positioning through credence attribute claims can be associated with product launch strategies, including brand-new products, expansion of product ranges, new packaging and relaunch, as a response to market demand.

Text analysis was used to investigate the descriptions of food claims using Structured Query Language, providing a word list of food claims and further filtered and categorised into groups of claims. Multinomial regression models were then employed to analyse the association between product launch strategies and food claims adopted by firms.

The results of this paper provide evidence that positioning via food claims play an important role in product launch strategies in both AU and NZ. Types of food claims matter differently to firms' product launch decisions in the two markets. The “green” and “ethical” attributes are found to be associated with new launches in NZ but not in AU. Claims that are seen as most important for consumers are more likely to be engendered for the more costly launch approach.

This study is amongst the first studies that addresses the role of positioning in product launch strategies of food companies. The results and findings provide insights into the different prevailing credence attributes from the firm side and help policymakers to regulate the delivery of information about credence attributes to consumers.

This paper aims to propose a framework model of belief consistency on the confirmatory bias theory, trying to explore the interactions between cues of credence-label structure and different controversial types of health foods, as well as the intermediary mechanism of belief consistency.

This paper presents a conceptual framework of belief consistency based on confirmation bias theory. The interactions between cues of credence-label structure and different controversial types of health foods, as well as the intermediary mechanism of belief consistency.

Consumers’ willingness to purchase varies under interactions between cues of credence-label structure (product-level and ingredient-level credence-label cues) and different controversial types of health foods (noncontroversial health foods and controversial health foods). In the consumption context of noncontroversial health foods, the presence of product-level credence-label cues causes confirmation bias, greater perception of health belief consistency and higher willingness to purchase healthy foods. In the consumption context of controversial health foods, the presence of ingredient-level credence-label cues results in the prevention of confirmation bias, lower perception of unhealthy belief consistency and higher willingness to purchase health foods.

This paper offers a significant tool for researchers to enrich relevant theories in the field of the conceptual framework of cues of credence-label structure. It also discusses practical implications for enterprise marketing and for the health and welfare of consumers.

The purpose of this paper is to disentangle the direct and indirect effects of three credence labels (Australian, animal welfare and grass-fed) on US consumer attitudes toward buying beef steaks. Furthermore, it explores the impact of consumer attribute knowledge, usage frequency, education and opinion strength on the magnitude of direct and indirect effects.

Data are collected through an online experiment with 460 US consumers and analyzed with path modeling.

The Australian label generates a 86 percent negative direct effect vs a 14 percent negative indirect effect on consumer attitudes, which means that US consumers do not make strong inferences to form their attitudes toward buying Australian beef. The animal welfare label generates 50 percent direct and 50 percent indirect effects. The grass-fed label generates only indirect effects (100 percent). The higher consumer education, attribute knowledge, usage frequency, education and opinion strength, the weaker are the indirect effects of credence labels.

The study focusses on consumers in one country (USA), one product (beef steak) and one label across three attributes, therefore generalization of results is limited.

The study offers a tool to agribusiness managers as well as to policy makers, NGOs and consumer groups to design and assess the effectiveness of communication campaigns attempting to strengthen (or weaken) consumer inferences and attitudes relative to credence labels.

Despite the wide literature on consumer inferences based on credence labels, this is the first study that quantitatively disentangles the complex set of inferential effects generated by credence labels and explores common relationships across multiple credence attributes.

This study aims to examine how the relative importance of a search versus a credence attribute, strategically addressed in a flu vaccination advertisement, varies as a function of message sidedness. A search attribute was designed to highlight the affordability of flu shots, and a credence attribute addressed the potential health benefits of flu vaccination.

Two experiments were designed to explore how the relative persuasiveness of search versus credence attributes varies as a function of message sidedness in the context of flu vaccination advertising. In Experiment 1, the search–credence attribute type was manipulated by addressing either the affordability (e.g. “Get free flu shots”) or indirect health benefits of flu vaccines (e.g. “Improve herd immunity/community health”). In Experiment 2, an individual-level credence attribute (e.g. “Strengthen your immune system”) was created and compared to the other two attribute conditions used in Experiment 1: a search versus a societal credence versus an individual credence attribute.

Experiment 1 (N = 114) revealed the relative advantage of a search attribute (free flu shots) in the two-sided persuasion. Experiment 2 (N = 193) indicated that the persuasive impact of a societal credence attribute (herd immunity/community health) was greater in the two-sided message condition (vs one-sided message condition).

Relatively little research has examined how consumers respond to strategic flu prevention and vaccination messages promoting either credence or search attributes. Motivated by the need to investigate the relative effectiveness of stressing “herd immunity” versus “free flu shots” in flu vaccination advertising, this study examines how the effects of these distinct attributes on flu vaccination judgments differ between two-sided (e.g. “No vaccine is 100% effective”) and one-sided persuasion.

This paper provides an approach for branding a service. It accomplishes this by bringing together David Aaker’s brand identity framework, the 7Ps of services marketing and the economic classification of goods. The 7Ps of services are product, price, place, promotion, physical evidence, process and people. The economic classification divides goods into search, experience and credence goods. Typical examples for search, experience and credence goods are a consumer durable, a restaurant and a doctor respectively. The branding efforts needed for each of these goods is different. The approach recommends what should be done in terms of 7Ps for each of the three types of goods and integrates this effort with their branding.

A model for analysis of consumer behaviour towards food is developed. This model is intended to bridge the gap between the objective quality approach pursued in food sciences, the product characteristics approach, and the subjectively perceived quality approach, the product attribute approach as pursued in the consumer behaviour literature. The focus is on the information processing by the consumer. Information on the product quality is supplied to the consumer in the form of cues received while shopping or consuming. A distinction is made between extrinsic and intrinsic cues, and between search‐, experience‐, and credence‐quality attributes. Within the credence attributes, three categories are distinguished: food safety, health, and all other credence quality attributes. It is demonstrated that public policy should use minimum standards for regulating food safety, information and consumer education on health issues and definitional standards to regulate the other credence qualities. In the case of search quality, no public intervention is needed. In the case of experience quality, reputation is a means of reducing the quality erosion inherent for experience quality attributes. In the case of those foods which are not sold prepacked over the counter, these means are restricted. Here the public regulators could consider backing up the private quality policy efforts on labelling by implementing traceability schemes and defining the requirements for specific label claims.

The purpose of this paper is to examine the involvement levels and the information search activity of consumers purchasing credence services, in terms of the extent of the search and the information sources used.

A survey was undertaken (n=400) examining consumers ' information search practices for a range of credence services in comparison to non-credence services (search and experience services).

Involvement in the search process is high in terms of importance but not interest. Somewhat surprisingly, consumers of credence services do not undertake a more comprehensive information search than non-credence service purchasers in terms of the use of external sources of information. They do, however, depend more on the opinion of salespeople, the experience of friends and the content of consumer reports.

The results of this study differ from similar work that was previously undertaken with students and also in the USA. It would be useful to establish more strongly whether age and culture have an impact on information search.

This is the first time that the information search patterns of consumers of credence services have been undertaken for a wide range of common purchases in the UK. It is also original in this area of research in that it utilises a cross section of the population and not students. Its findings are important to the providers of credence services when considering their marketing communications campaigns because it reveals which marketing communication tools are considered by the consumer to be influential.

Though the marketing literature offers an abundance of research on the topics of perceived risk, information search, and purchase intentions, very few researchers have empirically examined these constructs in the context of services. This research explores the linkages among these three constructs when services are classified on the basis of search, experience, and credence attributes. Specific hypotheses are developed and tested. The results of this study indicate that perceived risk increases along a continuum from search to experience to credence service purchases. Other hypotheses relating to information search length, information sources, behavioral intentions, and service attributes, received moderate support. Finally, managerial implications of the study were provided, along with directions for future research.

This study explores the determinants of growth of credence-based exports of yerba mate from Paraguay, potential for increased export growth, and the fragility of the credence-based export model. Much of the growth in value of yerba mate exports from Paraguay is due to positioning of the good within the universe of products where consumption is driven by perceptions of sustainable production and health benefits to consumers. Credence claims for yerba mate—benefits to indigenous producing communities, environmental sustainability under certain production processes, healthful alternatives to energy drinks—are now widely known, but the growth of this awareness came via a new entrepreneurial strategy of a single firm.

Primary information was collected through interviews of actors in the Paraguayan yerba mate value chain during spring/summer 2020. These included representatives from three exporting companies, processors, public institutions and indigenous producers.

The Paraguayan yerba mate export boom was stimulated through the careful cultivation of an image of healthful consumption and sustainable production processes. The cost of this cultivation was borne mainly by a single firm. Findings suggest that future marketing efforts will need to reinforce credence claims, highlighting the benefits to indigenous producers.

This case study explores the determinants of growth of credence-based exports of yerba mate from Paraguay, potential for increased growth, and the fragility of the credence-based model.

Findings are supported by field interviews with value chain participants and detailed analysis of extant data. The paper is the first to discuss the fragility of relying on credence attributes for long-term demand growth.
