Intermediation Can Replace Certification

We consider a market in which consumers do not have perfect information about product quality. Producers can perfectly reveal that a good is of high quality through certification, which entails socially wasteful costs. Firms can choose whether to sell through an intermediary or to sell independently (vertical integration). We show that multibrand retailing, which leads to a redistribution of profits but not to social costs, can fully or partially replace certification by signaling product quality. Renting the image of a competing high-quality brand is shown to be an outcome that can be sustained through intermediation.     

Consumer Feelings and Equilibrium Product Quality

This paper considers the possibility that a firm can invest not only in the true product quality, but also in activities such as merchandizing and store atmospherics that influence consumer perception of the product quality. Consumers make their purchase decisions based on the signal (perception) of quality they experience, where the signal is influenced by both the true product quality valued by the consumer and the affect of the consumer at the time of the signal formation. In this situation, a firm finds it optimal to invest in both product quality and in variables inducing affect, even though rational consumers, in equilibrium, correctly solve back for the true product quality. We uncover an asymmetry in the effects of the cost of producing quality and the cost of inducing affect. As a firm's cost of quality decreases, the firm will find it optimal to invest more both in the true quality and in the affect inducement, even if it does not have a lower cost of inducing affect. Conversely, if a firm finds it easier to induce affect, then the product quality decreases but affect-inducing activities increase.
Under competition, we find that the firm investing more in quality also invests more in affect creation. An implication of this is that in a competitive environment, consumers can rationally associate an up-lifting store atmosphere, affect inducing merchandizing, or mood-creating communication with high quality products even when the firm has no need to signal their private cost of quality information, and when there is no consumption externality of the affect. We also analyze the case in which firms might have different costs and consumers are uncertain about the costs incurred by a given firm. Here again we show that the perceived quality production is positively correlated with both the true quality and the affect inducing activities.     

Voluntary Quality Disclosure under Price‐Signaling Competition

We analyze an oligopolistic competition with differentiated products and qualities. The quality of a product is not known to consumers. Each firm can make an imperfect disclosure of its product quality before engaging in price‐signaling competition. There are two regimes for separating equilibrium in our model depending on the parameters. Our analysis reveals that, in one of the separating regimes, price signaling leads to intense price competition between the firms under which not only the high‐quality firm but also the low‐quality firm chooses to disclose its product quality to soften the price competition.

Postsearch uncertainty,product heterogeneity,and price divergence

We develop a consumer search model in which consumers may remain uncertain about product quality even after inspecting the product. We first consider the postsearch uncertainty regarding vertical quality, and characterize the separating equilibrium in which firms with different quality levels charge different prices. If quality information is not sufficiently transparent after the search, then prices between the low- and the high-quality products can either diverge or converge as the search cost decreases, depending on the degrees of horizontal and vertical product differentiation. We further extend the model to include the postsearch uncertainty about the horizontal match value and to endogenize the firm's quality choice.     

Integration of the Kano and QFD model in health food development: using black beans as examples

This study applied the Kano two-dimensional quality model and quality function deployment (QFD) to develop the black bean’s reputation as a health food and identify quality attributes of consumers’ needs in order to effectively control the attributes. This study first conducted a literature review and summarized the product’s quality attributes and then carried out expert interviews to determine health food quality attributes and consumer need quality attributes. A questionnaire survey was conducted to discuss which quality attributes of black beans consumers perceived to be important when they were presented as a health food and classify their answers using the quality attributes in the Kano model in order to effectively control consumers’ needs. Consumers’ demand for quality attributes was transformed into a technique of product quality development. In a matrix of the two constructs, quality classification of health food in the Kano model and order of consumers’ satisfaction with eating types of health food products, quality factors were transformed into technical specifications of product development for QFD and the construction of the first-stage of the House of Quality matrix. The results serve as references for companies to effectively distribute resources and establish strategies of product development, enhance product quality and consumer satisfaction, reduce product development time, and increase the success rate of products in the market. The results contribute to the health food enterprises are not only can make profit of product but also meet customers’ need.     

Oligopolies with (Somewhat) Environmentally Conscious Consumers: Market Equilibrium and Regulatory Intervention

We consider a horizontally differentiated duopoly where consumers care about the product's “greenness.” Firms can be asymmetric: they may differ in the product's intrinsic value and may also differ in their chosen level of greenness. We examine the choice of greenness and the implications of various policy interventions. We show that (i) the choices of product greenness are strategic substitutes, (ii) the high‐intrinsic quality firm produces the greener product, (iii) the low‐quality firm's greenness may increase with the cost of its provision or decrease with consumer willingness to pay for it, (iv) a minimum quality standard (MQS) leads the greener firm to lower its environmental quality and can even reduce average quality, (v) greenness is underprovided even if consumers fully internalize the externality, and (v) an MQS can reduce welfare if the greenness of the high‐quality firm exceeds the MQS, even when environmental quality is underprovided. The effects of policy interventions on profits differ qualitatively across polices and firms: A firm that lobbies for one type of intervention may lobby against another similar one, and a firm may lobby for an intervention while its competitor may lobby against it. A subsidy for the development costs of a green product can financially hurt both firms.     

Consumer Search with Limited Product Evaluation

Consumers need not evaluate all available product information before making a purchase. This may arise because shopping environments prevent a full evaluation (e.g., online). We develop a model of simultaneous search in which consumers have limited ability in product evaluation in order to study the impact of search cost on prices, consumer surplus, and social welfare. If consumers are endowed with the ability to choose how much information to acquire from a searched product, they may choose limited product evaluation. We find that consumers may evaluate more firms, enjoy lower prices, and higher surplus despite this limited ability. This implies that prices can decrease and consumer surplus can increase in search costs. We then extend our setting to the case of multiproduct firms and find similar effects due to changes in within‐firm search costs.     

Optimal advance selling discount strategy with future-oriented consumers

This paper examines the advance selling decisions over two periods and considers future-oriented consumers who are more concerned about the product quality than price discounts. We find that the advance selling strategy is not always best, and its merits are contingent on parameters of the market and consumers. Moreover, there is no need to set a deep advance selling discount for the retailer if consumers are highly risk averse. Next, we analyze the feasible advance selling pricing strategies for the retailer. Finally, we observe that the retailer can announce a higher advance selling price if consumers are moderately risk averse.

Competing Environmental Labels

We study markets in which consumers prefer green products but cannot determine the environmental quality of any given firm's product on their own. A nongovernmental organization (NGO) can establish a voluntary standard and label products that comply with it. Alternatively, industry can create its own standard and label. We compare the stringency of these two types of labels, and study their strategic interaction when they coexist. We find that even with error‐free labels, environmental benefits may be smaller with two labels than with the NGO label alone, and we characterize when label competition is more likely to be environmentally beneficial.     

Q-TAM: a quality technology acceptance model for technology operations managers

This paper contributes to research on the quality factors that affect customer acceptance and intention to continue purchasing disposable technology. We have developed a model (Q-TAM) that integrates the Technology Acceptance Model and a quality framework. We conducted a survey of 322 smartphones users and analyzed the results using Partial Least Squares – Structural Equation Modeling (PLS-SEM) to determine how our integrated Q-TAM model affected consumers’ intention-to-continue-purchasing disposable technology. The PLS-SEM analysis of the Q-TAM model established that consumers assessed the product quality based on two distinct dimensions: attribute quality and reliability quality. Further, we found support for the positive and significant effects of product quality and perceived ease of use as predictors of a customer’s intention to purchase a technological device. Of interest is our finding that perceived usefulness, in the presence of product quality, is not significant. The finding also suggests that customers perceive the usefulness of a product as a component/part of a product’s quality dimension, confirming Joseph Juran’s quality philosophy of “fitness of use.” This suggests that in order to satisfy consumer demands, technology operations managers must ensure their products are of good attribute and reliability quality. The findings of this study make a case for a quality technology acceptance model (Q-TAM) that encourages technology operations managers to focus their efforts on quality to ensure that their products satisfy customer needs and are perceived as useful.     

Search Engine Optimization: What Drives Organic Traffic to Retail Sites?

The lion's share of retail traffic through search engines originates from organic (natural) rather than sponsored (paid) links. We use a dataset constructed from over 12,000 search terms and 2 million users to identify drivers of the organic clicks that the top 759 retailers received from search engines in August 2012. Our results are potentially important for search engine optimization (SEO). We find that a retailer's investments in factors such as the quality and brand awareness of its site increases organic clicks through both a direct and an indirect effect. The direct effect stems purely from consumer behavior: The higher the quality of an online retailer, the greater the number of consumers who click its link rather than a competitor in the list of organic results. The indirect effect stems from our finding that search engines tend to place higher quality sites in better positions, which results in additional clicks because consumers tend to click links in more favorable positions. We also find that consumers who are older, wealthier, conduct searches from work, use fewer words, or include a brand name product in their search are more likely to click a retailer's organic link following a product search. Finally, the quality of a retailer's site appears to be especially important in attracting organic traffic from individuals with higher incomes. The beneficial direct and indirect effects of an online retailer's brand equity on organic clicks, coupled with the spillover effects on traffic through other online and traditional channels, leads us to conclude that investments in the quality and brand awareness of a site should be included as part of an SEO strategy.     

Green consumer behaviour: an experimental analysis of willingness to pay for remanufactured products

Products' end‐of‐life management has recently become a critical business issue. One of the possible end‐of‐life strategies is remanufacturing, which can provide competitive advantages through material and energy savings. Beyond industrial organization challenges, there is a question about the interest of developing a green marketing strategy for remanufactured products. Indeed, remanufactured products can be considered as green products since their industrial process has environmental benefits. Our paper asks whether consumers are willing to pay for remanufactured products, especially when they are informed that these products are ‘green’. We use experimental auctions to elicit consumers' WTP for specific characteristics of remanufactured products. Our study indicates that consumers tend to value the remanufactured product less than the conventional one unless they are informed about their respective environmental impacts. We find no evidence that consumers are willing to pay a premium for the green (i.e. remanufactured) product. However, providing environmental information to consumers has an effect on their WTP for the conventional product: they generally decrease significantly their WTP for the conventional (and thus most polluting) product.

Can consumer complaints reduce product reliability? Should we worry?

We analyze a monopolist's pricing and product reliability decision in a model where consumers are entitled to product replacement if the product fails, but have heterogeneous costs of exercising this right. Our main result shows that, under some conditions, a decrease in consumers expected to claim cost leads to a decrease in product reliability but an increase in profit and welfare. This result is robust to a number of extensions. Our results are in line with anecdotal evidence suggesting that changes in consumers’ claiming cost can be induced by both third parties (governments, consumers’ organizations, private enterprises, etc.) and firms. More precisely, since, under some conditions, profit and welfare align, public initiatives oriented to lower consumers’ claiming cost will be ultimately joined by firms that benefit from further increases in complaints.     

Implications of quality standard regulation for multiproduct monopoly pricing

An important concern of regulatory agencies is the quality and variety of products offered for sale. This paper considers the effects of introducing quality standards in a monopolized market where the monopoly sells a range of qualities of a product to consumers with varying taste for quality. The introduction of a minimum acceptable quality can alter the entire price and quality schedule offered by the monopolist. Both a uniform and a more general distribution of consumers are studied to examine these changes and their implications for general welfare.     

Quality and Location Choices under Price Regulation

In a model of spatial competition, we analyze the equilibrium outcomes in markets where the product price is exogenous. Using an extended version of the Hotelling model, we assume that firms choose their locations and the quality of the product they supply. We derive the optimal price set by a welfarist regulator. If the regulator can commit to a price prior to the choice of locations, the optimal (second-best) price causes overinvestment in quality and an insufficient degree of horizontal differentiation (compared with the first-best solution) if the transportation cost of consumers is sufficiently high. Under partial commitment, where the regulator is not able to commit prior to location choices, the optimal price induces first-best quality, but horizontal differentiation is inefficiently high.     

Differentiated‐product distribution in a dual‐channel supply chain

This study presents a theoretical framework to explore the mechanism of firms' preference for different distribution strategies. The results indicate that the manufacturer, retailer, and e‐tailer would prefer the distribution strategy of selling low‐end and high‐end products through offline and online channels, respectively, when consumers are minimally sensitive to the product‐quality differentiation. By contrast, supply‐chain firms would prefer the distribution strategy of selling high‐end and low‐end products through offline and online channels when consumers are significantly sensitive to the product‐quality differentiation. Firms demonstrate different preferences for distribution strategy when consumers are moderately sensitive to product‐quality differentiation.     

Consumer adoption of access-based product-service systems: The influence of duration of use and type of product

Access-based product-service systems (AB-PSS) are business models that can potentially decouple the satisfaction of consumer needs from environmental impacts. Hence, they have been promoted for the circular economy. Their sustainability potential has not yet been realised because consumer adoption is lagging. Although this challenge has been studied for two decades, knowledge to identify and address AB-PSS adoption barriers that matter to consumers is lacking. We hypothesise that the duration of use, the time a consumer obtains exclusive access to a specific product (short-term vs. long-term) and the type of product (bicycles vs. clothing) moderate the importance of AB-PSS adoption barriers to consumers. We compared several adoption barriers across four AB-PSS and found that the duration of use and the type of product significantly moderated the importance of some AB-PSS adoption barriers. More specifically, the Effort to access has a higher influence on consumer preference for short-term AB-PSS, whereas Product quality has a higher influence on consumer preference for long-term AB-PSS. We also found that Effort to access and Product characteristics were more important for bicycle AB-PSS, whereas Contamination and Product quality were more important for clothing AB-PSS. These insights help companies to identify and design out key AB-PSS consumer adoption barriers.     

Sustainable product innovation and changing consumer behavior: Sustainability affordances as triggers of adoption and usage

This conceptual paper argues that for sustainable product innovation to make a contribution to addressing sustainability issues, we need to understand not only why consumers adopt sustainable products but also what makes them use these in sustainable way. To explain how specific product features can change the ways in which consumers engage with sustainable products in the adoption and usage phase, we draw on affordance theory. Affordances refer to the potential for agentic action of users in relation to a technological object. We develop a conceptual framework that explains how sustainable product innovation can lead to the design of sustainability affordances that stimulate adoption and sustainable usage. The framework shows how three forms of agency—material, firm, and user agency—interact and together influence a product's sustainability affordances that drive adoption and a change in consumer behavior. The framework explains how trade-offs between a product's environmental features and consumer expectations regarding desired functionalities and user experience can be overcome.
