Abstract This study examines the impact of contextual factors on brand trust, brand loyalty and cross-buying from the perspective of the bottom of pyramid rural consumers in India. Two important contextual factors – distribution intensity and outshopping orientation – were used as the contextual factors. Effects of distribution intensity in the initiation and maintenance of consumer–brand relationships are first examined. Further, it explores the moderating role of in versus outshopping orientation in the formation and maintenance of long-term relationships between consumers and brands in bottom of pyramid markets. Data collected from 478 consumers in three villages in Gujarat, India, were analysed using structural equation modelling technique to test the hypothesized relationships using IBM AMOS 23 software. Distribution Intensity was found to positively influence brand trust. Brand trust was found to mediate the relationships between distribution intensity and brand loyalty and distribution intensity and cross buying. The importance of distribution intensity in relationship initiation was more pronounced for consumers who shopped from local retailers than those who did not. The study underlines the importance of distribution intensity of brands a relationship-based marketing strategy, especially in those products, where the switching costs are low. This study establishes the role of contextual factors in the formation and maintenance of consumer–brand relationships in the bottom of pyramid markets.

Abstract Reviewing and rating are important features of many social media websites, but they are found on many e-commerce sites too. The combination of social interaction and e-commerce is sometimes referred to as social commerce to indicate that people are supporting each other in the process of buying goods and services. Rgeviews of other consumers have a significant effect on consumer choice because they are usually considered authentic and more trustworthy than information presented by a vendor. The collaborative effort of consumers helps to make the right purchase decision (or prevent from a wrong one). The effect of reviews has often been researched in terms of helpfulness as indicated by their readers. Images are an important factor of helpfulness in reviews of experience goods where personal tastes and use play an important role. We extend this research to search goods where objective characteristics seem to prevail. In addition, we analyze potential interaction with other variables. The empirical study is performed with regression analyses on 3,483 search good reviews from Amazon.com followed by a matched pair analysis of 186 review pairs. We find that images have a significant positive effect on helpfulness of reviews of search goods too. This is especially true in case of short and ambiguous reviews.

Abstract This article strives to clarify the importance and the effects of cultural differences on consumer satisfaction after a service failure in an individualistic society (Canada) vs. a collectivistic society (Japan). We focus on young, educated consumers to analyze if the contrasts shown in the extant literature between these two cultures are still relevant in the case of young consumers of both cultures when confronted with a service failure and service recovery. We used 150 questionnaires from Japan and Canada, the design of which reflects our theoretical model. Respondents were asked to recall one of their own negative service experience and the service recovery that may have followed. Our statistical analysis is based on Hayes’s PROCESS that allows to test complex moderated and mediated relations. We find that Anger mediates the relation between failure severity and consumer behavioral responses (EXIT and NWOM) similarly for both Japanese and Canadian consumers. Importantly, compensation, involving procedural and distributive justice (i. e. time – speedy service recovery and money) both reduced consumer anger, more so for individualistic consumers. Surprisingly, interactional justice (e. g. courteousness, politeness, and signs of respect) had no impact on neither individualistic nor collectivistic consumers. Our findings suggest that service providers should first fix the negative emotional reactions as a result of service failure. They may reduce this emotional reaction offering monetary compensation to both Individualistic and Collectivistic consumers. Younger collectivistic consumers are not more sensitive to signs of respect and politeness than individualistic consumers, which may show that the younger generation of Japanese consumers is getting closer to the individualistic culture.

Abstract Business relationships provide the means to create and appropriate superior value in business markets. However, despite the proliferation of research on the phenomenon, many questions remain unaddressed. Previous work focused almost exclusively on value after its creation and its sharing between the two exchange partners. Consequently, the appropriation of value as well as its interaction with value creation remains relatively unknown. Similarly, a few studies have examined the role of relational variables and power asymmetry in customer–supplier exchange relationships. To fill this gap, this study aims to examine the influence of relationship quality and power on value creation and appropriation and ultimately, on satisfaction and relationship continuity. Based on the theory of social exchange, this study proposes a conceptual model, which positions value creation and appropriation as central variables in the nomological network of business relationships. A quantitative study of 174 suppliers was carried out in order to compare the theoretical model with the empirical reality. The results obtained show that the relationship quality promotes greater value creation and appropriation in ongoing business relationships. As for power, its influence differs depending on how it is exercised within the relationship. Moreover, the appropriation of value remains the main driver of partner satisfaction, a sine qua non condition for the continuity of the relationship. This present research contributes to a better understanding of value creation-appropriation in ongoing business relationships. By strategically managing their customer–supplier relationships, managers can create and capture greater value and gain a competitive advantage.

Abstract This paper addresses an important issue to find relationship between the brand image and its determinants. Based on a data set of 136 brand characteristics measured for 700 top American national brands obtained from a survey of 4769 respondents as well as secondary sources (Lovett, Peres, and Shachar. 2014. “A Data Set of Brands and Their Characteristics.” Marketing Science 33 (4): 609–17), this study adopted an established econometrics approach (Stochastic frontier analysis) that has not been extensively applied in the marketing literature. The approach discussed in this paper can be used as an analysis framework where the concept of efficiency is brought into the picture in analyzing the relationship between the brand image with its associates. It is found that competency and familiarity are two main features that increase brand equity, whereas perceived risk and excitement decreases it.

Abstract For many years, the movie industry has been characterized by a unique (compared to other industries) type of vertical contracting practice, called sliding-scale contracting whereby the distributor (studio) takes a much larger (usually around 70%) share of box-office revenues than the exhibitor (theater) in the week of a movie’s release, with the exhibitor’s share increasing, in gradual steps, over subsequent weeks. In this paper, we propose a game-theoretic model that provides a new rationale for these contracting choices. Specifically, we show that these contracts effectively resolve conflicts of interest between studios and theaters over movie release timing and display length, in a way that is beneficial for both parties. Our model also stipulates conditions under which sliding scale become dominated by aggregate deals, i.e. deals based on total rather than weekly box office revenue. The testable predictions based on these conditions can be used by future empirical research once the available evidence on the use of aggregate deals in practice goes beyond anecdotal.

Abstract This paper introduces a model for the diffusion of add-ons that consist of new industrial technologies embedded in mature products. These new technologies are targeted to improve attributes such as the performance, convenience, safety, etc., of the carrier product that incorporates them. Although the rationale for the purchase of the carrier product is driven primarily by mature market factors such as physical wear-out or changing personal needs, the innovative technologies embedded in the design of these products and the advantages they offer provide a competitive edge to the brands that incorporate them. We examine the potential growth of the market share of products that incorporate new technologies within this overall carrier market. We apply our model to the diffusion of green buildings that incorporate better thermal insulation through the use of new materials. For this purpose, we draw on surveys and industry data to estimate the parameters of the model.

Abstract While impulse buying has been conceptualized as a product of impulses, this study proposes that both reflective and impulsive determinants can outline impulse buying. Following a dual-system model that distinguishes between a reflective and an impulsive system, we hypothesized that unhealthy snack impulse buying can be differentially influenced by either impulsive system or reflective system as a function of self-regulatory resources. Participants in the experiment were randomly assigned to one of the conditions of the two-group design (self-regulatory resources depletion vs. control condition); then they were given the opportunity to take part in a mock store spontaneous buying situation. While the impulsive system was represented by impulse buying tendency and unhealthy snack buying habit, dietary restraint represented the reflective system. The dependent variables were the number of unhealthy snacks purchased and the percentage of unhealthy snacks purchased. The results provided the first empirical foundation for reflective and impulsive aspects of impulse buying behavior. The findings showed that self-regulatory resources moderate the impact of both reflective and impulsive determinants on unhealthy snack impulse buying. While the reflective system (dietary restraint) only determined the behavior in the high self-regulatory resource condition, the impulsive system (impulse buying tendency and habit) associated with the behavior when self-regulatory resources were diminished. There was one exceptional case in which habit determined the percentage of unhealthy snacks purchased even in the high self-regulatory resource condition.
