Purpose: The paper aims to address the issue of how customer value is created in the context of novel food products and how customer value influences product evaluation. Design/methodology/approach: The study proposes a model formed by a series of causal relations among value (i.e. functional, social, hedonic, altruistic values) and cost perceptions (i.e. price, effort, evaluation costs, performance and product safety), their trade-offs (i.e. overall customer value) and product evaluation outcomes (i.e. satisfaction, trust). Findings: Despite doubts about certain search (information), credence (safety) and experience (taste) attributes, perceptions about product quality, likeability and ethical image predominantly formulate customer value, indicating novel products’ potential to be evaluated positively by consumers. Research limitations/implications: The proposed model advances knowledge in the context of product innovation. Contrary to past research that focuses on consumer attitudes towards a manufacturing technology and individual technology-specific risks and benefits, the customer value approach refers to novel product-related consumer attitudes conceptualized as overall customer value; the latter results from product-related value-cost trade-offs, leading towards specific consumer–product evaluations. Practical implications: The customer value approach refers to the value from the adoption of a new product that underlies a relevant set of product attributes (e.g. quality, image, sustainability, price, convenience, taste, safety, etc.) Focusing on product attributes that generate gain – loss perceptions impactful on consumer – product evaluations is highly relevant for product managers concerned with new product development. Originality/value: The originality of this work lies in the successful contextualization and testing of an inclusive model that comprises both emotional and rational components, operational at the product level, to generate substantial insights on the widely unexplored interplay between consumer – perceived customer value and the generation of consumer – product evaluation outcomes.

Purpose: The purpose of this paper is to investigate possible cross-cultural consumer segments in the EU aquaculture market and provide direction and focus for marketing strategies for farmed fish products. Design/methodology/approach: Selected psychographic constructs (i.e. category involvement, domain-specific innovativeness, subjective knowledge, suspicion of novelties and optimistic bias) are tested as segmentation basis with the objective of defining a number of cross-border consumer segments with distinctive and clear-cut profiles in terms of consumer perceptions towards farmed fish. Findings: Based on the consumer psychographic profiles, three distinct segments are found: involved traditional, involved innovators and ambiguous indifferent, of which the first two constitute especially interesting targets for market positioning strategies for aquaculture products. Practical implications: The results of the segmentation analysis opens new horizons in terms of positioning and differentiation of fish products from the aquaculture industry according to the most important potential market segments. Originality/value: The current research brings insights into different pan-European consumer segments and their characteristics that allow for a corresponding differentiation strategy within the aquaculture industry. The fact that the segments tend to be uniform across all countries suggests a relatively homogeneous or converging European fish-related culture.

Responding to the appeal for more research on the contingencies that shape the relationship between CSR and corporate performance, this paper incorporates environmental CSR, sets up an experimental survey and employs multiple mediation analysis with the aim to test the mediating role of consumer attributions on the CSR elements–consumer responses relationship; and further to examine the degree to which attributions are controllable, i.e., specific CSR elements activate specific type of attributions. Results support that attributions have a strong predicting power on consumer outcomes. The right time of appearance and the appropriate amount of resources committed to a CSR campaign, through the dual type of attributions they activate (more positive, i.e., values-driven and less negative, i.e., egoistic), impact positively on consumer reactions. In this respect, the study adds to past research showing that attributions are controllable, i.e., specific CSR initiative characteristics of a impact on the dimensionality of attributions and, through that, on specific target-types of consumer responses. This study thus shows that the activation of a dual-level attributions’ system is ambivalent, dependent on the character of the CSR campaign. The fact that specific CSR elements (i.e., CSR Timing) activate dual-level CSR motives that act complementarily indicates that managers should be clear about the capabilities of the elements of their CSR initiatives and how much impact they expect those elements to have on consumer response.

Co-creation is a process that directly involves different stakeholders in the idea generation phase of a new product development process. A pool of 112 new aquaculture fish product ideas was obtained by applying a combination of creative and projective techniques to the co-creation process with consumers in six focus groups conducted in three European countries (Germany, France, and Spain). The subjectivity of qualitative data analysis (e.g., focus groups) is one of its recognised disadvantages. To overcome this drawback, a combination of specialised software (i.e., Alceste), along with word frequency, co-occurrence, and context checking, was applied to provide a different approach to data analyses in qualitative studies. The method identified the most salient dimensions behind the participants’ discourse (naturalness, quality, ethics, price, and health) and inferred the importance those dimensions had for them, thus proving the existence of a correlation of 0.7 between what the participants said (frequency of mention) and what they liked the most (importance). Overall, the exploratory approach proposed is deemed useful for drawing key conclusions from qualitative research, thus offering an alternative to traditional content analysis. In future, the results obtained may be useful for selecting the co-created ideas with the greatest potential to be well received in the market.
