A nested logit model of brand choice incorporating variety-seeking and marketing-mix variables

We model the effects of variety-seeking and marketing-mix variables on consumers' purchases of coffee using a nested logit model. We premise that on any given purchase occasion, the utilities of brands other than the one purchased on the previous occasion may be correlated due to the consumer's tendency to seek variety or to avoid variety. This results in a two-level hierarchical model where choice on any purchase occasion is conditioned on the brand purchased on the immediately preceding occasion. Such a structure accounts for variety seeking and inertia tendencies of consumers and is consistent with a hierarchical decision process, where consumers first decide whether or not to make a repeat purchase and then decide which brand size to purchase. The assumed hierarchical structure is shown to be consistent with observed coffee purchase behavior, and the model is shown to outperform a nonhierarchical logit model in predicting consumers' brand choices.     

How Attitudes Toward Product Categories Drive Individual Brand Attitudes and Choice

Three experiments examine the role of attitudes toward the category to which a brand belongs in consumers’ attitudes toward individual brands. The core findings indicate that what consumers think generally about a category affects their evaluations of singular brands belonging to the category. Study 1 demonstrates that both consumers’ attitudes toward a category as well as their relative attitudes toward a brand versus intracategory competitors drive overall attitudes toward individual brands. Study 2 shows that manipulating attitudes toward a product category affects attitudes toward, and purchase intention of, individual brands belonging to that category. Study 3 demonstrates that more versus less favorably evaluated categories are more likely to exhibit brand positivity effects in judgments of singular brands. The results suggest the practical importance of measuring attitudes toward product categories, as well as the utility of marketing interventions aimed at the category level.     

Effects of prior brand usage and promotion on consumer promotional response

We examine how prior purchases influence consumer response to promotional activity in brand choice decisions. To improve understanding of the nature of this influence, we separate previous purchases into those on promotion and those not on promotion, and consider their differential impact on subsequent brand choices. Impact may be observed at the brand level, category level, or both and we suggest circumstances in which each might occur. Across four product categories, consumer sensitivity to price, price promotions, and feature advertisements increases for all brands in the product category following a promotional purchase but also decreases for the most recently purchased brand. The magnitudes of the results indicate that prior promotional purchases influence choice more than prior brand usage does. We offer managerial recommendations regarding promotional activities, for both retailers and manufacturers.     

对已购品牌的危机反应：不同品牌危机类型对消费者购后行为的差异化影响研究

基于自我分类理论,文章研究品牌危机类型(能力相关型与道德相关型品牌危机)对消费者购后行为(重复购买与口碑传播)的影响。通过分析实验数据以及消费者实际购后行为数据发现,道德相关型品牌危机会导致更高的矛盾态度,从而产生更低的重复购买和口碑传播。在能力相关型品牌危机下,强自我品牌联结消费者的重复购买和口碑传播都显著大于弱联结的消费者,而且强联结的消费者面对本土品牌的重复购买和口碑传播要显著高于外国品牌;在道德相关型品牌危机下,强联结消费者的重复购买显著大于弱联结的消费者,而口碑传播没有显著差异。文章拓宽了品牌危机与消费者行为研究视角,并为品牌商正确认识品牌危机与消费者群体关系提供理论指导。     

The competing roles of variety seeking in new brand adoption

We examine how consumers' attribute-level variety-seeking behaviors can explain their propensity to adopt a new brand in the consumer packaged goods (CPG) market. We leverage consumers' purchase history among extant brands prior to a new brand introduction as an indicator of the new brand adoption upon its launch. We incorporate variety seeking at two product attribute levels – brand and flavor – and find that variety seeking along these two dimensions predicts different outcomes for new brand adoptions. The estimation results of our discrete-time hazard model show that consumers' brand-level and flavor-level variety-seeking behaviors affect their likelihood to adopt a new brand in different manners: consumers who purchase various brands are more likely to adopt a new brand, whereas those who choose various flavors are less likely to adopt a new brand. The results also show that the new brand's price promotions and in-store displays can affect the role of variety seeking in consumers' new brand adoption. We assess the robustness of our findings by replicating our empirical model with an additional measure of variety seeking as well as a variety-seeking measure in another product category.     

A comparison of two types of price discounts in shifting consumers' attitudes and purchase intentions

This study focuses on consumer responses to two different types of price discounts: 1) a price discount with and 2) a price discount without a minimum purchase requirement. The effects of the discounts are examined to the extent that they may change consumers' attitudes and purchase intentions regarding a particular brand, by moving it from consumers' hold set to consideration set. A three-phase study on fast-food services in China was conducted. The results of the study provide new empirical insights regarding how to use a brand categorization model to predict the effects of different types of price discounts on consumer purchase behavior. More specifically, this study demonstrates that when a price discount with and without a minimum purchase requirement is applied to a brand in a hold set, the brand moves from the consumers' hold set to the consideration set. However, the effects of the two types of price discounts on consumers' attitudes and purchase intentions are not significantly different. The results are discussed in relation to brand management and marketing strategies in consumer goods industries.     

Nutrition Ad Claims and Disclosures: Interaction and Mediation Effects for Consumer Evaluations of the Brand and the Ad

The effects of ad disclosure information on evaluations of the brand, the advertisement, and purchase intentions are postulated to vary across different ad claim types. In addition, consumers' product health perceptions are hypothesized to mediate the effects of the disclosure information and ad claim type on brand and ad-related evaluations. Results from a between subjects' experiment show that the health perception measure mediates the effect of the disclosure on brand and ad evaluations, but the interaction between the ad claim type and the disclosure is not mediated by the inclusion in the model of consumers' product health perceptions.     

Investigating the recall inhibition effect: A test of practical considerations

Alba and Chattopadhyay (1985, 1986) have demonstrated that having consumers think about a familiar brand can interfere with the retrieval of competitive brand names, including those that might otherwise be considered for purchase. However, their research is silent about two issues of pragmatic importance. First, is it possible to inhibit retrieval of the consumer's preferred brand? Second, can an unfamiliar brand evoke recall inhibition? Our findings indicate that recall inhibition does not extend to the preferred brand. Our findings further suggest that recall inhibition can be induced by cueing consumers with an unfamiliar brand name, but that such inhibition is less pervasive than evoked by a highly familiar brand name.     

品牌与国家联结、品牌刻板印象与消费者购买意愿的研究

基于品牌全球化背景，文章探究了品牌与国家联结核心构念的两个维度对消费者购买意愿的影响机制。实证结果表明，从国家联想到品牌的维度显著影响消费者购买意愿，并显著影响品牌能力，同时品牌能力在该维度对购买意愿的影响路径中起到部分中介作用：从品牌联想到国家的维度显著影响品牌温暖，并通过品牌温暖的完全中介作用对购买意愿产生促进效应。另外，品牌典型性正向调节了从国家联想到品牌的维度对品牌能力的影响路径。上述发现在理论上洞察了品牌刻板印象内容的两个维度如何受到品牌与国家联结的影响，厘清了品牌与国家联结以及品牌刻板印象如何作用于消费者购买意愿。在实践上为中国提升国家品牌形象，中国品牌推进全球化战略提供策略参考。     

Enhancing Environmentally Conscious Consumption through Standardized Sustainability Information

In today's retail marketplace, consumers receive little or no consistent brand‐level sustainability information, but this may change in the near future. Developing hypotheses based on the comparative brand processing and information disclosure literatures, we conduct a retail laboratory choice‐based experiment to test predictions related to the effects of brand‐level sustainability information on choices, product evaluations, and retailer perceptions. Compared to the status quo condition in which no sustainability information is provided for the product category at the retail point of purchase, the addition of positive (negative) sustainability information for the brand yields higher (lower) product evaluations and increased (decreased) brand choice. In addition, due to greenwashing concerns, many consumers may be skeptical of product‐level sustainability information, and we address the moderating role of this skepticism on retailer‐related perceptions.     

The impact of advertising along the conversion funnel

We assemble a unique data set that combines information on supermarket feature advertising with path-tracking data on consumers’ movement within the store as well as purchase information. Using these novel data, we trace out how advertising affects consumer behavior along the path-to-purchase. We find advertising has no significant effect on the number of consumers visiting the category being advertised. The null effect is precisely estimated. At the upper bound of the confidence interval, a one-standard-deviation shift in advertising increases category traffic by only 1.3%. We do find a significant effect at the lower end of the conversion funnel. A one-standard-deviation change in advertising (evaluated at the point estimate) increases category-level sales by 10%. We further decompose the impact on sales and find the increase is driven by the same number of consumers buying a larger number of products of the same brand. We find no evidence of spillover effects of advertising between categories that are stocked in proximity of each other, nor between different products in the same category. Two mechanisms are consistent with these patterns: consumers retrieve memory of the ad only when interacting with the category or only consumers wanting to purchase the brand choose to consume the ad.     

Peer presence promotes popular choices: A “Spicy” field study on social influence and brand choice

Retail research has highlighted how the presence of others can affect consumers' brand evaluations, purchase intentions, and choice behavior. This field study investigated whether the presence (vs. absence) of peers and other consumers, respectively, could influence consumers' propensity to purchase popular brands (i.e., a market leader) within a given product category. Consumers at a supermarket were observed when standing in front of a spice shelf and their choices were analyzed as a function of whether they shopped alone or in the presence of peers versus other consumers. The results revealed that peer presence, but not the mere presence of other consumers, increased consumers' inclination to make popular brand choices, and that this effect was mediated by their stated familiarity with the chosen brand. As such, peer presence seems to increase consumers’ reliance on heuristics and the accessibility of concepts linked to popularity, leading to congruent popular brand choices. Moreover, consumers shopping in the presence of others generally took a longer time before choosing a brand and touched slightly more products in the presence of other consumers. Taken together, these results contribute to theory refinement in social influence from ecologically valid conditions and offer a set of implications for companies, store managers, and people working in the food industry.     

Metaphor as Visual Thinking in Advertising and Its Effects: Focus on Brand Familiarity and Product Involvement

One of advertisers' favorite communication techniques is the visual metaphor. In fact, metaphor usage perennially increases in ad images. This study, which looks at consumers with varying levels of brand familiarity and product involvement, investigates how their attitudes and purchase intentions of are influenced by the persuasive effects of visual metaphors in various advertising conditions. The findings reveal that consumers' attitudes and purchase intentions are enhanced more by visual metaphor-based ads than nonmetaphor-based ads when the advertised product is in a low-involvement product category. Nonmetaphorical ads are found to have a more positive influence with high-involvement products than do metaphorical ads. The results show a significant three-way interaction effect. When the advertised product is in a low-involvement product category, visual metaphors lead to favorable brand evaluations and higher purchase intentions in the ads for a low-familiarity brand. However, nonmetaphors are more persuasive than visual metaphors only for the low familiarity brand in a high-involvement product category. Theoretical and practical implications are addressed in the discussion.     

A Multiple-discrete/Continuous Model of Price Promotion

Understanding the effect of temporary price reductions, or price promotions, on sales of consumer packaged goods is an area of ongoing interest, both in academia and in practice. Price promotions, however, are becoming an increasingly important method of managing consumer demand for fresh produce items. Modeling the impact of price promotions must take into account the differentiated nature of fresh produce and the fact that consumers tend to purchase multiple items of only a few of the products available to them. Neither a continuous nor a discrete model of demand is appropriate. In this paper, we apply a multiple-discrete/continuous model of fresh produce demand to study the impact of price promotion on retail apple sales. Our findings show that the brand switching/category incidence effect of promotion is closer to 65/35 than the more usual 80/20 rule (80 percent of the effect is brand switching and 20 percent purchase incidence) when the nature of the decision is appropriately taken into consideration.     

品牌原产地困惑对于消费者喜爱与购买本土品牌和境外品牌的影响

以消费者行为理论和品牌原产地效应的研究文献为基础，通过对调查数据进行统计分析，本文提出与检验了品牌原产地困惑对于中国消费者喜爱与购买本土品牌和境外品牌的影响作用。结论如下：第一，在中国现有环境下，消费者越是误认为一个本土品牌是境外品牌，就倾向于越喜欢这个品牌；越是误认为一个境外品牌是本土品牌，就倾向于越不喜欢这个品牌。第二，本土品牌知名度对于本土品牌原产地困惑和消费者喜好本土品牌之间的正相关关系有负向的调节作用；不过，境外品牌知名度的调节作用则不明显。第三，品牌原产地困惑对于中国消费者购买本土品牌有负向影响，对中国消费者购买境外品牌则无显著影响。     

Price Awareness and Consumers’ Use of Deals in Brand Choice

There is evidence that consumer knowledge of prices is limited, implying that, on occasions, consumers may not be fully informed of prices when making a brand purchase. On such occasions, how do consumers make their brand choice decision? One possibility is that consumers use their expectation of prices. This raises an interesting question. To what extent is brand purchase either a function of preferences and posted prices or, of preferences and expectation of brand prices? Another important issue relates to the role of displays and features in simplifying consumer brand choice. First, do promotions cause consumers to restrict their attention to only promoted brands? Second, do promotions affect the price aware consumers more than the price unaware consumers? Our study uses scanner data on ketchup and peanut butter categories to answer the foregoing questions. We find that between 40 and 50% of the purchases are made by consumers using expectations of prices rather than posted prices. Consumers using price expectations may be thought of as being “unaware” of prices. We also find that promotions cause some consumers to focus exclusively on promoted brands, and this effect is greater on the price aware consumers than on the price unaware consumers. Our findings have an important bearing on the rationality of consumer expectation of prices, especially of the promoted brands. Price aware consumers act as a check against firms promoting without accompanying price cuts.     

A Micromodel of New Product Adoption with Heterogeneous and Forward-Looking Consumers: Application to the Digital Camera Category

We develop an empirical model for the adoption process of a new durable product that accounts for consumer heterogeneity as well as consumers forward-looking behavior. Accounting for heterogeneity is important for two reasons. As the mix of consumers with different preferences and price sensitivities could change over time, firms need to update their marketing strategies. Further, it allows for a variety of shapes for the aggregate adoption process over time. As prices for durable and technology products fall over time with firms continually introducing enhanced products, consumers may anticipate these prices and improvements and delay their purchases in the product category. Forward-looking consumers optimize purchase timing by trading off their utilities from buying the product and their expectations on future prices, quality levels, and brand availability. Such forward-looking behavior will result in price dynamics in the marketplace as price changes today influence future purchases. And it results in different shapes of the new product sales pattern over time by influencing the time to take-off. We show how the parameters of our model can be estimated using aggregate data on the sales, prices, and attributes of brands in a product category. We apply our model to market data from the digital camera category. Our data are consistent with the presence of both heterogeneity and forward looking behavior among consumers. At the product category level, we are able to decompose the effects of the entry of Sony into primary demand expansion and switching from other brands. At the brand level, we find that there exist several segments in the market with different preferences for the brands and different price sensitivities leading to differences in adoption timing and brand choice across segments. For a given brand, we show how the changing customer mix over time has implications for that brands pricing strategies. We characterize how price effects vary across brands and over time and how price changes in a given time period influence sales in subsequent periods. Model comparison and validation results are also provided.     

Consumer Responses to Vertical Service Line Extensions

Vertical line extensions extend an established brand to products at different price/quality points. In this study, we examine consumer evaluations of vertical service line extensions and the feedback effects of these extensions on the parent brand. Findings of two empirical studies in the hotel industry indicate that consumers perceive higher risks in step-up extensions than in step-down extensions, which consequently influences their evaluations of the extensions. This effect of extension direction is also found to be moderated by risk relievers such as service guarantee and consumers’ prior knowledge in the service category. Furthermore, we found that a parent brand receives more positive evaluations after the introduction of a step-up extension than that of a step-down extension.     

Brand loyalty evolution and the impact of category characteristics

A common managerial belief indicates that brand loyalty declines over the years, with consumers becoming more heterogeneous in their choices. The earlier research investigating the phenomenon of brand loyalty decline is, however, inconclusive and does not offer an answer to the reasons behind brand loyalty evolution. In this study, we investigate brand loyalty evolution and explore the impact that a number of category characteristics have on driving brand loyalty evolution. We use Danish panel data across 54 categories over a period of 6 years (2006–2011). Our findings show that at the aggregate level, brand loyalty declines, but this evolution is category-specific, with only a small number of categories showing a significant decline. We further demonstrate that an increase in category penetration results in a negative impact on brand loyalty evolution, whereas an increase in the share of private label brands has a positive impact. We discuss the implications for theory and practice.
