An Analysis of Assortment Choice in Grocery Retailing

Consumers in grocery retailing commonly buy bundles of products to accommodate current and future consumption. When all products in a particular bundle share common attributes (and are selected from the same product category), the consumer is said to assemble an assortment. This research examines the impact of assortment variety on the assortment choice process. In particular, we test the prediction that consumers demand less variety for higher quality items. To investigate this relationship, we employ a flexible choice model, suitable for the analysis of assortment choice. The model, based upon the assumption that the utility of purchase of one item in an assortment depends upon the set of items already selected, allows for a general utility structure across the assortment items. We apply the model to household assortment choice histories from the yogurt product category. Substantively, we show that yogurt choice is affected by brand quality perceptions (quality-tier competition). Moreover, we show that reaction to reductions in variety (number of yogurt flavors) is mediated by brand quality perceptions. Taken together, these empirical facts paint a picture of a consumer who is willing to trade-off variety against product quality in assortment choice.     

Bridge,Focus, Attack,or Stimulate: Retail Category Management Strategies with a Store Brand

We investigate a monopolist retailer's category management strategy where the main strategic decisions are how to horizontally position a store brand relative to the incumbent national brands and how to price the store and national brands for retail category profit maximization. We analyze a market composed of two consumer segments with differing tastes and heterogeneity with respect to willingness to pay and a product category consisting of two competing national brands and one store brand. We find that contrary to the existing literature, it is not always optimal for a retailer to position its store brand against the leading national brand; instead there are many situations where it is best to position the store brand close to the weaker national brand or to position it in the “middle” so it appeals to both national brands' target segments. In the process we identify four distinct category management strategies that a retailer can use with a store brand. In three of these the optimal store brand price is the brand's monopoly price, while in the remaining one strategy the price is lower. We also suggest an easy to implement means for a retailer to determine which strategy is best to use, depending on the particular competitive environment present before the introduction of the store brand and the relative quality of the store brand. We find that the store brand entry is most beneficial to the retailer when the national brands are moderately differentiated. Finally we show that introducing a store brand not only allows the retailer to garner a higher share of the channel profits through higher retail margins, but also often provides the retailer the benefit of increases in national brand unit sales as well as incremental sales from the store brand.

Money-back guarantee and pricing decision with retailer's store brand

This paper investigates the money-back guarantee (MBG) choice problem in the presence of store brand introduction in a two-echelon supply chain consisted of one manufacturer and one retailer. Game-theoretic models with different MBG policies regarding the national brand and the store brand are examined. We found that the MBG policy could be a strategic tool to help the retailer developing its store brand even when a fairer policy is chosen by the retailer and the store brand is considered by consumers as a low-end substitute for the national brand. The presence of MBG is beneficial to the retailer while unfavorable to the manufacturer, even though the retailer provides a fairer MBG policy, i.e., MBG for both two brands. Although the national brand has advantages over the store brand, MBG will increase the competition and cause customer shifting from the national brand to store brand and thus bring a profit loss for the manufacturer. Moreover, we have found that the manufacturer could provide coordinate contracts for the retailer to improve its performance with which a win-win outcome could be reached for both the manufacturer and the retailer.     

Category management,product assortment,and consumer welfare

In this article, we endogenize product assortment decisions under a category management (CM) framework in a channel setup. We find that (1) product assortment is polarized more under CM than under a non-CM regime; (2) the price of a high-end (low-end) product in an assortment increases (decreases) under CM than under a non-CM regime; and (3) a high-quality manufacturer makes more profit than a low-quality manufacturer. In our model, the manufacturer’s choice of quality and its polarization is driven by the existence and the decisions of the retailer (CM or non-CM). Finally, we have an interesting result on consumer welfare. We find that the total consumer welfare, as measured by consumer surplus, worsens under CM only when there is sufficient heterogeneity in consumers’ tastes.     

The effect of shelf layout on satisfaction and perceived assortment size: An empirical assessment

This research compares the effect of different shelf visual layouts on decision satisfaction and perceptions of the retailer assortment, with a focus on how (e.g. vertically vs. horizontally) to display products rather than on how many products to display. The combined evidence from three experimental studies shows that displaying assortment breadth horizontally and depth vertically led participants to perceive a larger selection and to be more satisfied. Furthermore, linear displays increase decision satisfaction but decrease perceived assortment size and preference strength for the top brand, whereas visual layouts with the preferred brand in the central position increase decision satisfaction, make the assortment appear larger, and enhance preference strength for the top brand. The findings provide guidelines about how to organize products on the shelves and suggest that – even when actual assortment size is constant – consumer responses to the assortment depend from how the retailer displays the products.     

The fight between store brands and national brands—What's the score?

In the Western world market shares for store brands have increased across all product categories. The competitive position of store brands compared to national brands may depend on the product category and a retail chain's overall brand assortment strategy. In order to investigate these possible chain and category effects we have selected five chains with different store brand strategies and three product categories that differ with respect to the number of strong national brands in a category. The results we report focus on the competitive position of store brands compared to national brands from a consumer point of view. We find that store brands are in a weak competitive position compared to national brands independent of category and retail chain brand assortment strategy.     

Brand and quality effects on introduction of store brand products

This paper considers a supply chain with a single manufacturer selling a national brand product via a single retailer. The retailer has the option to introduce a product under his own brand into the market with the same functionality as the national brand product. We simultaneously consider the consumer bases of the national brand and store brand along with consumers' willingness to pay for quality and the supply chain control (centralized vs. decentralized). By analyzing the game-theoretic models, we offer managerial insights about the influences of brands' consumer bases on the quality and pricing decisions of the retailer, and on the manufacturer's willingness-to-collaborate when the retailer introduces the store brand product. We find that, although it is usually easier for the retailer to introduce a product under a store brand with a large consumer base, doing so with manufacturers of well established national brands can be difficult, when the retailer often has to greatly mark down his store brand product's quality and price. We also find that a store brand product with a small consumer base shall be launched only when the supply chain is switched to a centralized control and when the manufacturer's national brand has a large consumer base. These important findings offer guidance to both national brand manufacturers and retail store managers regarding the launch of store brand products.     

Brand vulnerability to product assortments and prices

Abstract

The assortment of brands that a specific brand competes against varies from one point of sale to another. The competitive landscape changes further because of within-assortment price variations at each location. The joint variation in assortment composition and pricing creates a complex set of scenarios under which a brand needs to compete. In this paper, we develop an approach to assess changes in a brand's vulnerability under alternative assortment and price configurations. We specifically propose that, in market environments with high variability in the competitive set and prices, it is more appropriate to assess a brand's strength relative to alternative assortment configurations rather than against individual competing brands. We build a model that depicts a brand's vulnerability in latent assortment space rather than the traditional brand space. The results from an illustrative model application are used to draw inferences about changes in brand vulnerabilities under shallow and deep promotions.     

Customer choices of manufacturer versus retailer brands in alternative price and usage contexts

This article offers a context-dependent theory of how price changes influence consumer purchase choice for fast moving consumer goods (FMCGs) for manufacturer (large household share) and retailer (small household share) brands. The theory proposes that the influence of price on demand is systematically very sensitive to context effects; more specifically, the theory includes the hypothesis that elasticity is much greater when the price change results in the manufacturer and retailer brands having the same price compared to when the price change keeps the manufacturer brand price above the retailer brand price. The implicit and/or explicit association with higher quality with the manufacturer versus retailer brand may be the main reason for buying the higher priced manufacturer brand. Decreasing the price of the manufacturer brand to equal the retailer brand's price takes away the primary reason for buying the retailer brand (i.e., saving money); increasing the price of the retailer brand to equal the manufacturer brand's price has the same effect. The empirical findings in the studies that this article reports support the hypothesis and confirm Scriven and Ehrenberg's [2004. Consistent consumer responses to price changes. Australas. Mark. J. 12(3), 21–39] major conclusion that relative order of price is more important than relative distance.     

Creation of consumer loyalty and trust in the retailer through store brands: The moderating effect of choice of store brand name

Within the current economic context, store brands play an important role in differentiation strategies based on assortment and positioning in terms of distributor prices. To begin with, this study identifies three determining aspects of retail loyalty and trust: satisfaction with price levels, the perceived image of the assortment and loyalty to the store brands (SB). Secondly, this study proposes a theoretical relational model among the aforementioned aspects. Finally, this study analyzes the moderating role that the strategy of choosing SB name (umbrella brand label vs. brands different from the label brand) plays in the relationship between loyalty to SB and loyalty to and trust in the retailer. By including this moderating variable, we seek to contribute to current academic research and to provide insights into the importance that SB strategy (label vs. own name) has for the effect of loyalty to SB on the relative results of the retail company. Our research results show that making the umbrella SB name the same as the label brand name increases the positive effect of customer loyalty to SB on loyalty to the retailer, but not the effect of trust on this loyalty compared to chains that use SB names different from those of the label. These results have important implications for management.     

Integrative effects of firms' price and endorsement strategies on consumers' loyalty intention

This research examines the effects of price and brand endorsement that are adopted by firms from a consumer-based viewpoint, and provides practical brand management discussions as a reference for both manufacturer brands and retail store brands. According to the findings, manufacturer brands support high prices and boost those vivid impressions which are helpful in engendering consumer loyalty intention. Without a careful evaluation process, a brand-endorsing strategy may prove detrimental to the manufacturer. Retail store brands follow distinct pricing policies and carry out brand-endorsed strategies. Price/endorsement stimuli influence consumer brand loyalty through the partial mediating effect of brand impression. Manufacturers and retailers could define appropriate price premiums on products with a potential for a manufacturer–retailer brand co-branding as identified by market research, thus increasing the sales of both.     

Retailer Dynamic Pricing and Ordering Decisions: Category Management versus Brand-by-Brand Approaches

This paper provides a framework for retailer pricing and ordering decisions in a dynamic category management setting. In this regard, the key contributions of this paper are as follows. First, we develop a multi-brand ordering and pricing model that endogenizes retailer forward buying and maximizes profitability for the category. The model considers (i) manufacturer trade deals to retailers, (ii) ordering costs incurred by the retailer, (iii) retailer forward buying behavior, and (iv) both own- and cross-price effects of all the brands in the category. Second, we use this model to compare differences in ordering and pricing decisions, and in profits, resulting from using a category management versus a brand-by-brand management approach. Our approach allows us to derive implications in a dynamic setting about the impact of interdependence among the brands upon decisions on pass-through of trade deals and retailer order quantity. We show that category management results in noticeably higher profits versus brand-by-brand and cost-plus (markup) approaches. Further, our results suggest an interaction between a brand's own-price effect and its cross-price effect emerges. If the cross-price effect for a brand is low - that is, the brand takes away relatively few sales from the other brands - the retail pass-through should increase with that brand's own-price effect. On the other hand, when the cross-price effect is high, the retail pass-through decreases with the brand's own-price effect.     

Store Brand Quality and Retailer’s Product Line Design

This study analyzes a retailer’s store brand quality decision in vertically differentiated product categories. We analyze a game theoretic model composed of one or two national brand manufacturers and a retailer, who strategically chooses the quality level(s) of its store brand(s) relative to the well-established national brand position(s) to maximize its category profit. Our analysis reveals that the nature of a retailer’s store brand quality positioning is quite different from the manufacturer’s national brand positioning decision, and that the best position for a store brand is not “as close to a national brand as possible” as previous studies suggest. Instead, the optimal quality position of each store brand is remarkably sensitive to the distribution of consumers’ willingness-to-pay. In particular, the relative proportions of quality sensitive consumers and price sensitive consumers determine the balance of three key strategic forces — the market expansion force, the retail margin force, and the consumer profitability force, leading to different optimal product line designs for store brands across different category environments. Interestingly, against multiple incumbent national brands, the retailer’s optimal product line design includes a store brand positioned at the highest quality level in the category only if most consumers are moderately quality conscious. We also analyze the implications of national brands’ brand equity for retailers’ store brand strategy.     

Forging meaningful consumer-brand relationships through creative merchandise offerings and innovative merchandising strategies

This research highlights the importance of retailer-consumer identity congruence – the match between the retail brand identity and the consumers’ identity. Retailers can leverage identity congruence to forge meaningful consumer-brand relationships which will result in enhanced engagement, brand loyalty, and willingness to pay. The paper discusses how creative merchandise offerings and innovative merchandising strategies contribute to the creation of a unique retail brand identity and facilitate communication of this identity to consumers. Based on interviews with retail practitioners, we formulate five ways in which retailers can establish and communicate their brand identity through creative merchandise offerings (by focusing on unique and original merchandise, leveraging local merchandise to reflect the area, making their merchandise akin to art, offering sustainable merchandise, and a high fashion product assortment). In addition, we focus on five innovative merchandising strategies which help the retailer connect the brand to the customer (creating themes, reflecting the brand story, being playful, signaling exclusivity, and virtual merchandising). We then discuss how retailers can utilize social and technological tools to amplify the retailer identity to consumers, thus increasing the likelihood that a consumer will view their identity congruent with the retail brand.     

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.     

An Empirical Investigation of Composite Product Choice

Prior ingredient branding research has examined the influence of “stated” factors such as fit between partner brands on composite product (e.g., Tide with Downy fabric softener) attitudes. This research focuses on choice of composite products, and addresses three managerially relevant questions: Which consumer segments are more likely to adopt the composite product? Will the choice of the composite product have positive or negative reciprocal effects on partner brands? Will the introduction of the composite product benefit the primary or the secondary brand more? The authors use a brand choice model to investigate the “revealed” choice of complements-based composite products. Study results indicate that (i) despite high fit between the composite product and the primary brand, consumer segments may have different choice likelihoods for these products, whereas prior research suggests equal likelihood; (ii) the choice of a composite product may not provide a positive reciprocal effect to the secondary brand; and (iii) the introduction of a composite product may benefit the primary brand more than the secondary brand, whereas prior research suggests a symmetrical benefit for the partner brands. Finally, the finding that introducing a composite product may not cannibalize the sale of the primary brand extends the ingredient branding literature, which has been silent on this issue.     

The impact of household level heterogeneity in reference price effects on optimal retailer pricing policies

The field of marketing has witnessed substantial improvement in modeling household level heterogeneity. However, relatively little has been written about how modeling household heterogeneity translates into better marketing decisions. In this paper, we study the impact of household level heterogeneity in reference price effects on a retailer's pricing policy. Reference prices are certain anchors or standards that households use to compare the observed purchase price of a product against. If the observed price is greater than the reference price it is perceived as a “loss” and if it is smaller than the reference price it is perceived as a “gain”. In order to study the impact of heterogeneity in reference price effects on retail pricing, we test a nested logit model under two alternative reference price (memory and stimulus based) and heterogeneity (finite mixture and hierarchical Bayes) specifications. In the empirical analysis, we find that households are quite heterogeneous in terms of their gain and loss effects. For some households a gain has higher impact than a corresponding loss, while the opposite is true for others. Using individual level estimates we then develop a normative pricing policy for a retailer maximizing category profit. Our results indicate that the optimal pricing policy derived from the heterogeneous case is qualitatively different, and more profitable, than the case when heterogeneity is ignored. We show that for an important marketing problem pertaining to a retailer, the optimal pricing decisions for various brands in a category are inextricably related to household heterogeneity in reference effects and brand preference.     

A Positive Theory of Private Label: A Strategic Role of Private Label in a Duopoly National-Brand Market

This article offers an economic rationale for national brands to provide private labels to their retailers. We build a game-theoretic model that analyzes the interactions among two national brand manufacturers and one common retailer. In an interesting strategic role, the private label mitigates the promotion competition between the two national brands and provides benefits for all three members in the channel. Our analysis shows that offering a private label can be a credible commitment from a national brand manufacturer that it will not engage in promotions and decrease the incentive of the national brand rival to engage in promotions. In this way, we attempt to provide a reason for why national brand manufacturers provide retailers with private labels in practice. In addition, we discuss the optimal quality level of private labels.

Determinants of Store Brand Share

Private labels or store brands have witnessed considerable growth in the last few decades, especially in grocery products. However, market shares of store brand vary considerably across categories, markets, and countries. A natural question of interest to academics and practitioners is what factors influence store brand market shares. Drawing on a utility framework, we develop 21 consumer, manufacturer, retailer, and product-market characteristics that can influence store brand share. We test the empirical generalizability of the effect of these determinants through a meta-analysis of data from 54 individual and aggregate market studies. Twenty of the 21 determinants show significant, empirically generalizable effects. We discuss the key findings, their implications, and directions for future empirical research.
