Enhancing Concept Test Validity by Using Expert Consumers

In standard concept testing practice, consumers may be invited to participate in a test if they use or possess the product. However, merely using or possessing a product is no guarantee that a consumer has the level of product knowledge that is necessary for judging the concept. Conducting a concept test with consumers who lack the necessary product knowledge may jeopardize the validity of the test results. That is, the results of such a concept test may not accurately indicate how consumers will evaluate the real product. To ensure the validity of concept test results, Jan Schoormans, Roland Ortt, and Cees de Bont suggest that consumers who are invited to participate in a concept test should possess a degree of product knowledge. When a consumer is asked to evaluate a concept, their product expertise allows them to understand product information faster, fill in missing information, and learn more easily. Consumers with product expertise are better able to discriminate between important and unimportant aspects of a product. They are also better able to infer benefits from a product's physical attributes. To explore the effects of consumer expertise on the quality of the evaluations provided by concept tests, the authors conducted two experiments, both of which resemble actual concept tests. The first experiment examines the effect of consumer expertise on the results of a concept test for a major innovation, Videotext. This experiment tests the hypothesis that the similarity between the evaluations of a concept and an actual product will be greater for consumers with a high level of product-category expertise than for consumers with low product-category expertise. The results of the experiment clearly support the idea that product-category expertise enhances a respondent's ability to evaluate concepts in a test of major innovations. From this, it is concluded that only respondents with high product-category expertise should be used for concept tests of major innovations. The second experiment explores the effects of product expertise on consumers' evaluations of a minor innovation, a redesigned coffee maker. This experiment tests two hypotheses. First, it is proposed that consumers with high product expertise give more consistent evaluations in a concept test than consumers with low product expertise. Second, it is suggested that consumers with product expertise generate more stable evaluations over time than consumers without product expertise. The results of this experiment clearly indicate that using consumers with moderate to high levels of product expertise is beneficial to the validity of the results from concept tests of minor innovations.     

Applying Hedonic Pricing Models and Factorial Surveys at Parker Pen to Enhance New Product Success

Walking the path from new product concept to successful commercialization is a tightrope act. Product developers must carefully balance a variety of factors, including predictions of consumer price sensitivity as well as which combination of product attributes will be most valued by the intended market. A well-chosen mix of analytical tools can enhance a firm's chances of accurately predicting market demand. Chuck Tomkovick and Kathryn E. Dobie describe how the integration of two product attribute assessment techniques–hedonic pricing models and factorial surveys–allows product designers to more accurately gauge price sensitivity and market receptivity to new product designs. They also describe how these analytical tools were used to improve decision-making in product development at the Parker Pen Company, and they discuss the role these tools can play in facilitating the transition from concept to commercialization. Hedonic price analysis is an econometric method for determining the value purchasers place on attributes of existing products. In product development, factorial surveys are used to identify the value members of the target market place on new product concepts and prototypes. When used in combination with identified hedonic prices, the responses to a factorial survey allow product developers to predict consumer willingness-to-pay for various combinations of new product attributes. Following development of prototypes for two new product lines, product developers at the Parker Pen Company used hedonic pricing models and factorial surveys as a means for reducing demand uncertainty and for clarifying what consumers were willing to pay for various combinations of product attributes that were under consideration. The integration and use of these techniques involved a five-step process of target market identification, product attribute identification, hedonic price estimation, administering of the factorial survey, and determination of consumer willingness-to-pay. The results of these analyses allowed Parker Pen to better focus product development efforts on those design elements for which test market customers indicated both demand and willingness-to-pay. The Parker Pen Company found hedonic pricing and factorial surveys useful for predicting both the rate and the degree of change in consumers' marginal utility for specific product attributes. The usefulness of these techniques also extends beyond the early stages of new product conception. These techniques are helpful in the development and implementation of dynamic new product marketing mix strategies, including such elements as product design, pricing, channel selection, and promotion.     

Consumer inference and the regulation of consumer information

When consumers are uncertain about the importance of a product attribute, mandatory disclosures have two effects: directly communicating attributes, and an inferential effect that changes how much weight consumers put on product attributes. I model a signaling game between regulators and consumers in which regulators perfectly reveal their private information about the importance of an attribute through the intensive margin of regulation. The model has empirical predictions that distinguish it from traditional models of mandatory disclosure. I also examine inferential mistakes that can lead to over or under-regulation and consumer over or under-estimates of the importance of product attributes.     

The Role of Product Originality,Usefulness and Motivated Consumer Innovativeness in New Product Adoption Intentions

Prior research has posited that product attributes are primary drivers of success that a firm must consider to develop a competitive advantage. Two product attributes, originality and usefulness, have been identified in the literature as significant dimensions of new product success. Customer demands differ, and more purchase intentions toward a new product depend on how consumers connect the product attributes to their own individual characteristics. Studying motivated consumer innovativeness as a personality trait may improve our understanding of the motivations for adopting innovations; however, questions remain regarding whether the effects of originality and usefulness on consumers' intentions to adopt are different when levels of these attributes are matching or dissimilar and what the relationship is between these effects and motivated consumer innovativeness. This study seeks to empirically investigate these effects and their relations by collecting data from 560 potential consumers in China. This paper uses hierarchical regression analysis to test hypotheses in four product domains as representative of higher or lower levels of usefulness and originality. The research shows that new product originality affects consumers' intentions to adopt new products only if it matches the level of new product usefulness. The results also reveal that motivated consumer innovativeness has a positive moderating role on the relationship between new product originality and consumers' new product adoption intentions when both attributes are at a lower level. The theoretical and practical implications for new product development and marketing communications are discussed.     

The choice between uniqueness and conformity in mass customization

Extant research emphasizes that consumers use mass customization toolkits to create products they consider to be unique, and that perceived uniqueness is an important part of customer value. This research investigates the conditions of the customer's quest for uniqueness. It is motivated by the observation that decisions are often driven by others’ choices and a desire to fit in, rather than to be distinct. We hypothesize that consumers are more inclined to choose uniqueness for hedonic product attributes but tend toward conformity in utilitarian attributes, and that consumers’ need for uniqueness and product involvement moderate the choice. In a series of experiments, we find support for most hypotheses. We introduce conformity as a driver of choice behavior in mass customization toolkits and suggest that mass customization can best be seen as enabling consumers’ preferred mix of uniqueness and conformity. Our results also inform managerial practice, highlighting that mass customization toolkits should consider customers’ uniqueness and conformity requirements. We suggest reducing the number of utilitarian options while increasing the variety for hedonic attributes.     

Seeking the Ideal Level of Design Newness: Consumer Response to Radical and Incremental Product Design

To develop successful new products, new product development managers need to have a thorough understanding of the consumer adoption process, specifically in how consumers evaluate new products. This research examines the value of product design for consumers' evaluation of radical and incremental innovations. The primary goal was to empirically test how design newness affects consumer response to product innovations. Design newness (also referred to as novelty or atypicality) is defined as the deviation in a product design from the current design state of a certain product category. Although prior research has suggested that higher levels of design newness may have a positive effect on consumers' evaluations of new products, higher levels of design newness may also have negative consequences for consumer response to radical innovations. An experimental context (n = 130) using systematically designed products for three product categories was used to test how consumers respond to high and low levels of design newness for both radical and incremental innovations. The findings show that for radical innovations, embodying the product in a design with a low (versus high) level of design newness led to more positive evaluations and less learning‐cost inferences. Because the functional attributes of a radical innovation are incongruent to existing products, consumers find it difficult to access the relevant product category schema in order to transfer knowledge to the new product. Because of this poor knowledge transfer, consumers may feel that they lack the ability to make effective use of the radical innovation, resulting in greater learning costs. In this case, a product design with a low level of design newness can provide consumers with a frame of reference for understanding the radical innovation. Contrasting this result, no difference was found between a low and a high level of design newness for incremental innovations. For incremental innovations, by definition the functional attributes characteristic to the innovation are highly comparable with those products that are already stored in consumers' memory. Thus, there is no need for an additional reconfirmation of the preexisting schema through product design, and consumers are able to access the relevant schema regardless of the level of design newness inherent in the product. These findings are integrated into a discussion of the managerial implications and the potential avenues for future research.     

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.     

Information,Promotion, and the Adoption of Innovative Consumer Durables*

The diffusion of innovative new products is critically dependent on the transmission of relevant information to potential adopters. Existing research indicates that the relative effectiveness of different communication tools depends on the type of information being communicated. Written and verbal communication tools can be effective when consumers make adoption decisions based on search attributes. However, when adoption depends on experience attributes, marketers must find ways to effectively expose consumers to these attributes. In this paper the authors explore the effectiveness of promotional incentives in motivating consumers to engage in behaviors that should increase their understanding of an innovation's experience attributes. To the authors' knowledge, the research described here is the first published study of the relative effectiveness of different promotional vehicles in stimulating adoption of a consumer durable. The empirical analysis is based on data collected in a real‐world experiment involving 614 households. Just over half of these households received a free DVD movie disc as an incentive to participate in the study. The authors assigned the participating households to four treatment groups of 100 households each and a control group of 214 households. The households in the treatment groups received one of four promotional offers that featured some form of a $50 monetary incentive. These promotional offers differed in the degree to which they encouraged behavior that exposed consumers to the experience attributes of a DVD player. After one month the authors surveyed these households again to determine how many purchased a DVD player in the preceding month. An analysis of this experimental data reveals that all four monetary promotions significantly enhanced the probability of adoption. In particular, the average adoption rate among the households receiving one of the monetary incentives was 41%. In contrast, none of the households in the control group reported purchasing a DVD player. Promotions that paid consumers for specific behaviors that precede purchase were no less effective than a coupon that reduces the purchase price by an equivalent amount. In addition, promotions that directly exposed consumers to experience attributes were more effective than promotions that simply provided consumers with the opportunity to learn about experience attributes. Finally, the gift of a free complementary product (a DVD movie) enhanced the effectiveness of three of the four monetary promotions. The authors close with a discussion of managerial implications and directions for future search.     

An Exploratory Study of the Innovation Evaluation Process

In their search for the keys to successful product innovation, product managers and researchers typically focus on trying to identify the most effective organizational processes, strategies, and structures. Surprisingly, little or no effort is directed toward understanding the process that consumers use for evaluating an innovation. By gaining insight into this evaluation process, a firm can present an innovative product in a more effective manner and thus increase the likelihood that consumers will respond favorably to the innovation. Richard W. Olshavsky and Richard A. Spreng provide insight into this process by describing the results of an experiment in which subjects were asked to evaluate several innovative concepts. From their observations, they develop a model of the detailed information-processing steps that these consumers employed in order to evaluate the new products. Consistent with previous research, they found that judgment was the predominant evaluation strategy, particularly for the most innovative concepts. Various subjects also used a categorization strategy, though none used categorization for more than four of the nine concepts that were evaluated. Contrary to expectations, none of the evaluations relied solely on the manufacturer's reputation or the recommendation of a friend. In a simplified model of the evaluation process, when presented with an innovative concept, consumers first attempt to categorize the product. In other words, an innovation may be rejected simply because consumers somehow link it to an existing category that has a negative connotation. If consumers cannot categorize the product, they then employ a judgment process based on some evaluative criteria. Based on the data collected in this study, this simplified model is extended to include four other cognitive processes that strongly influence the evaluation process: forming evaluative criteria, forming expectations about the innovative concept, assessing satisfaction with an old product, and comparing the new and old products. When faced with a highly innovative concept, consumers may find it difficult to form their own evaluative criteria and expectations concerning that innovation. Consequently, managers may have an opportunity to shape the judgment process by educating consumers about the appropriate evaluative criteria or by clearly communicating the product's attributes, benefits, and appropriate use.     

Quality certification vs. product traceability: Consumer preferences for informational attributes of pork in Georgia

Consumer willingness-to-pay for informational attributes of food products is important information for food producers and supply chain participants and policy makers. We examine consumer demand in the pork sector of the Republic of Georgia. Results of conditional and mixed logit estimation, conducted on choice experiment data, reveal that Georgian consumers treat quality certification and product traceability attributes as substitutes. We also find that producers and other supply chain participants should be concerned primarily with maintaining the appearance of pork products. Retailer specific factors such as location and type of outlet can also substitute for product traceability. Store location and product appearance, however, are complementary attributes. In light of the recent turbulence in Georgia these consideration may be of paramount importance as participants in the supply chain seek to rebuild damaged infrastructure.     

The Impact of Seasonality on the Launch of Infrequently Purchased Products

Few published articles have dealt with the unique problems associated with the management of new, infrequently purchased products that exhibit seasonal patterns of demand. Marvin Berkowitz demonstrates how seasonality influences the performance of a new consumer durable good, a new brand of battery-operated lights, during a 2-year period following its launch. The data presented support four hypotheses: (I) the newest brands in a product category, when compared to dominant brands, will be subject to higher seasonal variation in consumer awareness, advertising recall, product attribute positioning, and purchase intent; (2) the relationship between seasonal effects and brand share within a product category will not be linear; (3) differences between product attributes for competing brands will be most apparent to consumers during periods of peak seasonal activity; and (4) perceptions of product attributes that are most important in the buying decision are subject to the least seasonal variation. The article also demonstrates how seasonal variations may be charted and discusses how this analysis contributes to the overall management of the new product.     

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.     

Combining attitudinal statements with choice experiments to analyze preference heterogeneity for functional dairy products

In this article, we employ a discrete choice experiment to examine preferences for functional dairy product attributes and willingness-to-pay estimates for consumers in Germany. We estimate preference heterogeneity by linking stated preference choice data not only to socioeconomic characteristics but also to attitudinal statements in a latent class framework. The empirical results indicate the existence of class-specific preference heterogeneity based on the consumers’ attitude towards functional foods, emphasizing the importance of attitudinal data in explaining consumers’ choice behavior. Our estimates demonstrate that within a class, consumers’ preferences are in accordance with their responses to attitudinal statements, that is functional food skeptics prefer non-functional dairy products, while functional food advocates have a negative preference for non-functional dairy products. The findings also show that all consumers place high value on dairy products enriched with known functional ingredients such as omega-3 fatty acids.     

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.     

Referrals in search markets

This paper compares the equilibrium outcomes in search markets with and without referrals. Although it seems clear that consumers would benefit from referrals, it is not at all clear whether firms would unilaterally provide information about competing offers since such information could encourage consumers to purchase the product elsewhere. In a model of a horizontally differentiated product market with sequential consumer search, we show that valuable referrals can arise in the equilibrium: a firm will give referrals to consumers whose ideal product is sufficiently far away from the firm's offering. We allow firms to price-discriminate among consumers, and consumers to misrepresent their tastes. We found that the equilibrium profits tend to be higher in markets with referrals than in markets without. Consumers tend to be better off in the presence of referrals when search costs are not too low, and under a certain parameter range, referrals lead to a Pareto improvement.     

Willingness to pay for over-the-top services in China and Korea

The increasing penetration of broadband and multiscreen availability has encouraged the development of premium video consumption through over-the-top (OTT) services. Netflix, the leading global OTT provider, is aggressively expanding its international operations and has ambitiously entered the Asian market. To prepare for the shift that the streaming service giant will bring, a proper understanding of consumer acceptance and intent to pay for OTT services is crucial. Therefore, this empirical study uses conjoint analysis to investigate the key attributes and to examine consumers’ marginal willingness to pay (WTP) for OTT services. We identified recommendation systems, resolution, and viewing options as important product attributes of OTT services that influence the WTP of Chinese and Korean consumers. The most important attribute for Chinese consumers of OTT services was resolution, followed by the recommendation system and viewing options. For Korean consumers, the recommendation system was ranked as the most valuable attribute, followed by viewing options and resolution. The overall WTP of Chinese consumers was 22.6 yuan (3.4 USD) per month, while Korean consumers’ intent to pay amounted to a total of 3530 won (3.1 USD) for OTT services.     

Being Innovative While Being Green: An Experimental Inquiry into How Consumers Respond to Eco‐Innovative Product Designs

Eco‐innovations are an effective way for companies to strategically align themselves with customers’ growing environmental concerns. Despite their crucial role, scant research has focused on eco‐innovative product designs. Drawing from the sustainability and innovation literature, this article proposes that in the design of an eco‐innovation, its degree of innovativeness, level of eco‐friendliness, and detachability significantly affect consumers' adoption intentions. This article develops various conceptual models tested through three independent online experiments with U.S. consumers. The findings support the hypotheses and provide useful insights into the underlying mechanisms of how and why consumers respond to eco‐innovative product designs across various high‐tech product categories. Specifically, the results show (1) a positive effect of innovativeness degrees of eco‐innovative attributes on consumers' perceptions of product eco‐friendliness and on their adoption intentions as well as a significant moderating role of consumers' need for cognition (Study 1); (2) a positive influence of eco‐friendliness levels of eco‐innovative attributes on consumer adoption intentions in the case of high‐complexity products but not for low‐complexity products, emphasizing the need to adopt different approaches when developing eco‐innovations to ensure favorable consumer reactions (Study 2); and (3) a significant impact of the detachability of eco‐innovative attributes on consumers' perceptions of trade‐offs between environmental benefits and product functionality and on their intentions to adopt eco‐innovations (Study 3). These findings add to existing theoretical knowledge, provide actionable managerial implications, and identify fruitful avenues for future research.     

Individual antecedents to consumer intention to switch to food waste bioplastic products: A configuration analysis

Food waste management remains a significant economic and sustainability problem and is being actively addressed by scholars, governments, and organizations around the world. Bioplastics, which are biodegradable plastics derived from food waste, are a recent innovation that might contribute to managing this waste in a more sustainable manner. Unfortunately, many of today's consumers are not necessarily ready to consider such alternatives. Consumer switching to sustainable products is a tenuous topic, as consumers often value other product attributes (i.e., cost, quality, and associated prestige) more than their sustainability attributes (i.e., fewer natural resources expended, lower carbon footprints, and end-of-life recoverability). A greater understanding of consumers' intention to switch to bioplastic products provides opportunities for firms to develop state-of-the-art, profitable, and sustainable food systems. Considering the complex set of inter-relationships surrounding consumer involvement in sustainable innovations and associated supply chain strategy, this research leverages complexity theory and a qualitative comparative analysis research approach to uncover eight different, yet equifinal, configurations of antecedents that motivate consumer intention to switch from new plastic products to equivalent products made from bioplastics.
