Balancing Profitability and Customer Welfare in a Supermarket Chain

We investigate the impact of price discrimination by a large Chicago supermarket chain. First we measure the impact of the chain's current zone-pricing policy on shelf prices, variable profits and consumer welfare across its stores. Using the chain's database to simulate a finer store-specific micro-pricing policy, we study the implications of this policy on profits and welfare. We show how a store-pricing policy that is constrained to offer consumers at least as much surplus as a uniform chain wide pricing policy still enables the retailer to generate substantial incremental profits.To ensure our pricing problem exhibits a well-defined optimum, we use the parsimonious, mixed-logit demand function that allows for flexible substitution patterns across brands and also retains a link to consumer theory. We discuss the issue of price endogeneity when estimating the demand parameters with weekly store-level data. Standard instrumental variables techniques used to account for such endogeneity also seem to increase the magnitudes of own-price elasticities thereby offsetting the problem encountered by previous researchers of predicted prices from a demand model exceeding those in the actual data.     

Price recall: Brand and store type differences

Price is among the most important choice criteria for customers, whose price knowledge is often surprisingly inaccurate. This study aims at providing new insights into differences in price recall across brands and store types, and their potential effect on marketing efficiency and customers’ store choice. Towards this aim, we analyze the price recall of consumers for 51 food items by a random-effects panel estimation employing a survey with 715 participants. Our results show that customers recall national brand prices better than private labels, almost irrespectively of the store type; consumers overestimate store brand prices in both store types; the effect, however, is much higher for the convenience store. These outcomes have consequences for the marketing strategy: despite a price-matching guarantee for the store brands in the convenience store, the price image is still in favor of the discounter. This result raises doubts on the effectiveness of the price-matching guarantee, at least in this context. The everyday low price strategy of the discounter seems to pay off in terms of the price image. Though both stores charge the exact same prices for their store brands, prices at the discounter are on average perceived to be significantly lower.     

Retailer Categorization: How Store-Format Price Image Influences Expected Prices and Consumer Choices

Prior research indicates that consumers may base their retail decisions (e.g., store choice, purchase quantity) on price image, which has been defined as consumer perceptions “of the aggregate price level of a retailer” (Hamilton and Chernev 2013, p. 2). The present research shows that consumers associate different price images not only with specific retailers, but more broadly with various store formats — such as grocery stores, convenience stores, and specialty stores. Six studies provide evidence that store-format price image exerts influence on consumer price expectations and store choice decisions, and that these retailer categorization effects are distinct from the effects of retailer price image.     

How Do Price Perceptions of Different Brand Types Affect Shopping Value and Store Loyalty?

This research investigates the relationships among price perceptions for different brand types (national brands, standard store brands, regional store brands, organic store brands), shopping value dimensions (quality, price, social, and emotion value), and store loyalty (retention and word of mouth (WOM)). A comprehensive model depicts determinants of customer store loyalty. Using structural equation modeling, the model test includes 671 consumers intercepted during shopping trips. The data analysis yields several surprising results. In particular, low product price perceptions do not necessarily signal negative store quality evaluations. Shopping value dimensions influence store retention loyalty and WOM behavior differently. Furthermore, different brand types exert distinct effects on the value creation process. Favorable prices for national and standard store brands have comparable positive effects on store price value and emotional value creation; appealing prices of regional store brands instead reduce the emotional value of the store, and low prices for organic store brand products significantly increase social value creation.     

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.     

Main-format dominance in consumers’ FMCG cross-format shopping patterns

Although cross-format patronage has become a common phenomenon in markets for Fast Moving Consumer Goods (FMCG), research on consumers’ specific cross-format combinations is limited. We study such shopping patterns by focusing on retail format utilization. A qualitative pre-study demonstrates consumers’ patronizing combinations of typical retail formats in FMCG with main-format usage and provides underlying differences in consumers’ perceived shopping utility for cross-format selection, which results from their utilized main-format. Our quantitative study reveals three clusters with main-format dominance, that is, mainly supermarket, discount store, and hypermarket shoppers complementarily utilizing fill-in formats to a much lesser extent. Whereas we found high inter-format loyalty in each consumer group, intra-format loyalty significantly varies between clusters. ANOVA and post hoc-tests concerning perceived shopping utility dimensions show that consumers’ perceived acquisition utility rather than perceived transaction costs significantly differs between consumer groups.     

The Impact of Store-Price Signals on Consumer Search and Store Evaluation

Always low price (ALP) and low price guarantee (LPG) are store-price signals that retailers frequently use to induce favorable store-price image and discourage consumers from comparing prices across stores. Although both policies signal low prices, only LPG is an obligatory promise to beat rival stores’ prices. Results of two shopping simulations show that when consumer search costs are relatively low, ALP may effectively discourage consumer search whereas LPG may trigger more search. Paradoxically, consumers tend to evaluate ALP stores less favorably (as having lower integrity and higher self-serving intention) than LPG stores even when both signals appear to be credible. These findings suggest that LPG is a superior tactic for creating a favorable store image while ALP is more effective for discouraging consumer search. The results also indicate that consumers visit fewer stores when the LPG is not a credible signal of lowest market price than when it is credible. This is because consumers are inclined to either claim discounts or refunds at the non-credible LPG store or to purchase at the competing store with a lower price rather than continue searching.     

Growth factors of store brands in different store formats in Italy

Since the beginning of the consumer crisis, which in Italy can be traced back to the second half of 2008, there has been a significant development of store brands? market share which has reached close to 25% in some leader groups (for example Coop, Conad, Esselunga). The acceleration of the rate of penetration of store brands differs by category and store format. The main reason for this result is the different consumer purchase behavior. In this framework, this work aims at analyzing the elements that have determined the store brands success in the main store format (hypermarket, supermarket, convenience store), through analysis of single retail mix levers management. The factors that have mostly influenced the growth in store brands, in each store format, are investigated throughout a complete informative retail database. The aim of this study is to verify whether the management of the individual retail mix levers produces the same results in different store formats. Additional enhancement to the understanding of store brands management and further support to modern distribution management policies are also provided. A relevant finding is that the performance of store formats depends on the use of specific retail mix levers.     

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.     

The Effects of Background Music on Consumer Responses in a High-end Supermarket

Abstract

This study examines the effects of in-store background music valence (liking) and music fit with the overall store image on consumer evaluative and behavioural responses in the context of a high-end supermarket chain. Based on the previous body of work, a conceptual model is developed to examine music valence on customer appraisal of store offering and personnel, and on the length of shopping time and the value of purchase. The influence of the perceived music fit with the overall store image on shopping time is also assessed in the model. The hypothesized relationships are examined via covariance analysis using store-intercept consumer data. Implications of the structural analyses results for management of retail store brands and for future research on music as an element of store atmospherics are discussed.     

Price Knowledge During Grocery Shopping: What We Learn and What We Forget

Past research on consumer price knowledge has varied considerably partly due to differences in how and when price knowledge is measured. This paper applies a multi-point, multi-measure approach to reconcile differences in past price knowledge research by examining systematic relationships between time of measurement and type of measures applied. Examination of consumer price knowledge before, during, and after store visit sheds light on what is measured at the individual points in time: episodic price knowledge and/or reference prices? With a between-subjects design interviewing 1,204 respondents, the authors investigate three price knowledge measures (price recall, price recognition, and deal spotting) demonstrating that these are hierarchically related. Results suggest that reference prices dominate before store visit, but also that episodic price knowledge, surprisingly, is still accessible at the store exit. These findings enable the authors to reconcile diverging results from past research, showing how consumer price knowledge evolves and suggesting that the vast majority of consumers learn about prices, whether consciously or unconsciously, during grocery shopping. Thus, when applying a multi-point, multi-measure approach, consumers appear to know more about prices than suggested by past research. Determinants of price knowledge are also examined and the results indicate that price knowledge builds up not only because of active search but also due to accidental exposure to prices and with low degrees of conscious processing. Implications for managers are discussed.     

Consumer attitudes and loyalty towards private brands

Private or store brands improve the efficiency of consumer decision making by offering equivalent quality products at lower prices. The present study evaluated consumer attitudes towards private brands with the goal of understanding their appeal in order to enhance efforts to convince more consumers to buy them. We used three samples (ns = 279, 245 and 305) of US consumers to compare attitudes of buyers of private and national brands in three product categories: orange juice, cereal and bottled water. The results show that private label buyers (23% of orange juice, 6.5% of cereal and 14% of bottled water buyers) consider brands themselves to be less important and private brands to offer better performance than do national brand buyers. When asked about specific brands, national brand buyers tended to be price insensitive towards national brands, and private label buyers price insensitive towards store brands. In addition, the national brand buyers saw some of the national brands to be more relevant to their lifestyles and needs, but the private label buyers saw the private labels the same way. Being relevant to consumers' lives appears to influence brand selection. Besides touting lower prices, private brand promotions might stress the equivalent performance of private labels and create promotions showing how these brands can be relevant to consumers' lifestyles and needs.     

An Investigation of Consumer Brand Choice Behavior Across Different Retail Formats

There has been a blurring with respect to the retail formats because of competition and proliferation of different types of formats. In this research, we use a unique scanner panel dataset to investigate how brand choice behavior varies for the same consumer shopping for the same brand across different retail formats. We develop hypotheses pertaining to promotion sensitivity, price sensitivity, package size preference, and effects of demographic and shopping variables on consumer brand choice behavior and test them using a multi-format probit choice model that allows for the estimation of the cross-format differences with respect to the above. We find that consumers exhibit different promotion and price sensitivities in brand choice behavior between the mass merchandise format and supermarkets. Discussions and insights are provided.     

Robustness of an Intermittent Program of Comparative Retail Food Price Information

This study compares the distribution of food-item market basket prices across stores and relative to a local newspaper retail food price report. Distributions of prices for market baskets comprised of national brands and cheapest alternative brands coincided closely with the intermittent retail food price report. This suggests that consumer organizations with limited resources can produce comparative food-store price reports that provide useful information to consumers.     

Consumers’ multifaceted deal knowledge in a grocery retail setting

Despite its relevance to retailers, studies of consumers’ deal knowledge have been few. This study explores consumers’ deal knowledge before, during, and after the store visit applying a between-subjects field-study design with 1204 respondents. In particular, the authors investigate perception of deal price status, typical deal price knowledge, and deal-spotting ability. Results show reasonably stable knowledge of typical deal prices, while knowledge of deal price status and deal-spotting ability improves significantly during grocery shopping. Surprisingly, consumers’ deal knowledge is not conditional on purchasing a special thus indicating that most consumers, consciously or unconsciously, scan for promotion signals when shopping groceries. In addition, the results suggest consumers are not easily fooled, as the vast majority is able to spot ‘good’ and ‘bad’ deals, while also possessing typical deal price knowledge. Furthermore, the findings suggest that consumers store internal reference deal prices. Retailers are therefore well advised to consider mixed depth and creative discount patterns to prevent ‘perfect’ perceptions of typical deal prices.     

Consumer responses to characteristics of price-matching guarantees: The moderating role of price consciousness

The present study develops and tests a conceptual model of consumer response to different types of price-matching characteristics (i.e., refund depth, length, and scope) across consumer segments with varying levels of price consciousness. A computer shopping simulation results show that a deep refund is interpreted as a signal of low prices by nonprice conscious consumers. However, price conscious consumers are found to associate deep refunds with increased prices, an unintended outcome for the retailer. The effects of price-matching characteristics on search and purchase behavior were also found to vary across more and less price conscious consumer segments.     

Loyalty differences in the use of internal and external reference prices

Recent findings in reference price research suggest that consumer characteristics may affect whether they use an internal reference price (IPR) or an external reference price (ERP) in price judgments. In this paper, we investigate the role of one such characteristic, brand loyalty, in the use of either type of reference price. Specifically, we employ a latent class-type approach to divide consumers on the basis of their brand loyalty into an ERP and an IRP segment. Analysis of the margarine and liquid detergents categories shows that consumers who are highly loyal to a brand are likely to use external reference prices whereas less brand-loyal consumers rely on internal reference prices. We discuss the implications of this finding and suggest directions for future research.     

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 comparative analysis of differential consumer response across supermarket and specialty store in the candy category

Retailing industry has undergone tremendous change in its complexity and sophistication over the past few years. Globally we are witnessing the evolution of retailing industry from traditionally micro-managed small retail formats like mom and pop store to modern corporate-managed large retail formats like supermarkets. Consumers are also shopping across these various store formats even for the products in similar categories. In this research, we posit that consumer purchases in the similar categories may very well be characterized by differential responses to marketing mix across different store formats. The proposed model accounts for the influences that these diverse response parameters and preferences have on one another as well as consumer heterogeneity. Our results show that sensitivities to marketing mix as well as correlations in preferences do indeed vary across formats for consumer purchases in similar categories.     

Buyer Power,Transport Cost and Welfare

Manufacturers produce substitute products and sell to consumers in a linear city through competing retail stores. A low cost store obtains large market share by selling at low prices. Assume that a big retailer may exert buyer power by demanding wholesale discounts from manufacturers. The model identifies exclusionary effects of buyer power against competing retailers. It is also found that certain level of buyer power of a discount retailer may maximize social welfare, while that of a regular price retailer may maximize total consumer surplus. Nevertheless, excessive buyer power hurts both consumers and society.
