Heterogeneous consumers,search and retail formats

This paper proposes a model featuring the heterogeneity of consumer preferences and analyzes the multiple equilibrium of retail formats by building a map of the relationships between consumer heterogeneity and retail formats. The key questions analyzed in this paper are how the retailer adjusts its combination of marketing elements through repositioning and how innovation in retail formats is implemented to match consumers’ heterogeneous preferences in a market with consumer search costs. Unlike recent research, our model, by taking different consumer preference structures into account, introduces consumer psychological costs into the Ehrlich-Fisher model and deduces the existence of different retail formats and their multiple equilibriums. We find that consumer heterogeneity, retailers’ diversified transfer costs and economies of scale are endogenous drivers of prosperous retail formats. Accordingly, diversified retail formats with complementary functions and differentiated services can be described as the horizontal extensions and interface changes of the retailing industry.     

Buying Groceries in Brick and Click Stores: Category Allocation Decisions and the Moderating Effect of Online Buying Experience

The large majority of online grocery shoppers are multichannel shoppers who keep visiting offline grocery stores to combine convenience advantages of online shopping with self-service advantages of offline stores. An important retail management question, therefore, is how these consumers divide grocery purchases across the retailer's online and offline channel. We provide a comprehensive analysis of the impact of category characteristics on the allocation pattern of multichannel grocery shoppers and find that category allocation decisions are affected not only by marketing mix differences between the online and offline channel, but also by intrinsic category characteristics like perceived purchase risk and shopping convenience. In addition, we examine the effect of online buying experience. In line with expectations, we find that it can affect allocation patterns in different ways: (i) it attenuates the perceived risk of buying sensory categories online, thereby reducing differences in online category share, (ii) it reinforces marketing mix (assortment) effects, thereby making online category share differences more pronounced, and (iii) it has no effect for factors such as promotions that are easy to evaluate without experience, thereby leaving the online category share stable. In addition to different experience effects across allocation factors, we also observe variations in experience effects across consumer segments.     

Internal reference price response across store formats

Reference price models have a long tradition in marketing and consumer research. Pricing strategies can utilize consumer response to gains and losses relative to internal reference prices, which are price expectations developed from past-observed prices. Consequently, many previous studies have been devoted to analyzing differences in internal reference price response across product categories and consumer characteristics. However, knowledge about internal reference price response across different store formats is missing. Our study aims to fill this research gap. To do so, we estimate a reference price model for the same set of brands and the same sample of consumers across two store formats (discount chain vs. supermarket chain). The prices for the brands in our model are similar across store formats. Results from our proposed model show that the same consumers are loss-averse at the discount chain while gain-seeking at the supermarket chain. Predicted by previous literature, we attribute the difference in internal reference price response to the different price image of the store formats. Overall, our research contributes to the reference price literature and provides important implications for pricing strategies at stores with different price image.     

Should retailers adjust their micro-marketing strategies to type of outlet? An application to location-based store space allocation in limited and full-service grocery stores

Many retailers today operate strategically different types of sites: ‘limited-service’ stores—that offer all core products/services but only a shallow assortment of non-core services—and ‘full-service’ sites with deep lines of both core and non-core services. An important question for these retailers is whether and how to adopt a micro-marketing strategy in each of these formats. In a micro-marketing strategy, retailers tailor their marketing mix to the characteristics of the local market in which each store outlet operates—a central issue being whether the allocation of store space across product categories should be location-specific. This paper (i) examines the conditions for such micro-marketing to be beneficial, and (ii) in particular—how these benefits depend on store format. It also (iii) indicates how the pattern of space adjustments to local conditions should differ between formats. The propositions are tested in a grocery retail setting, for a retail chain operating limited-service supermarkets and full-service hypermarkets. Our results suggest that micro-marketing is beneficial in both types of format. Yet, the appropriate way of localizing space allocation patterns is format-specific. While supermarkets should primarily adjust the space shares of food (core) categories, hypermarkets should primarily adapt the space shares of non-food (non-core) categories to local market conditions. The outcomes of the study have conceptual as well as managerial relevance and may prove useful for multi-format retailers in a wide range of settings.     

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.     

Shopping Style Segmentation of Consumers

The World Wide Web has rapidly become an alternative means to reach customers and has attracted the attention of many businesses. Unfortunately, however, despite its growth, there is little knowledge of which consumers would be willing to switch to the new format and to what extent. Our paper is aimed at providing some insights into these questions. Specifically, we propose a model to identify segments that differ in their shopping style, i.e., in their preference for which format, or bundle of formats, they like to shop in.Our research question, and model, is similar in spirit to prior research in marketing on how consumers choose assortments. Despite this similarity, our research makes some substantive and methodological contributions to the literature. Substantively, we examine the issue of the choice of channel assortments by consumers across a variety of product categories. We believe this is an important question and one that has not been examined earlier. From a methodological point of view, our model adds to earlier work by specifying the utility of an assortment as a sum of the deterministic and stochastic components of the utilities of its members. This contrasts with previous research where only the deterministic components of the utilities of the component brands of an assortment are added and the relationships between their random components are not accounted for.We calibrate the model on data regarding the format choices of households. In order to control for potentially similar format preferences across purchases of different categories we specify the model to allow for correlation between format preferences over the choice history of each household. Our results suggest that there are four segments of consumers that differ in their preference for different types of formats.     

Polygamous Store Loyalties: An Empirical Investigation

Grocery store loyalty has been traditionally viewed as a trait of consumers toward a particular store for their overall shopping needs. In this study, we argue that store loyalty shall be regarded as category specific trait, that is, a consumer could be loyal to store A in category one while at the same time be loyal to store B in category two. We name this consumer behavior polygamous store loyalties.We use an in-home scanning panel dataset that tracks purchases of 1,321 households in 284 grocery categories across fourteen retail chains over a 53-week period in a large US market. First, we provide model free evidence of polygamous store loyalties in the data, even though the overall store loyalty based on the traditional view is low. Next, we propose a model to separate category specific effects from overall store level effects. Finally, we discuss how retailers can use the results to gain a new perspective on store attractiveness to improve overall store patronage.     

Store and store format loyalty measures based on budget allocation

In highly competitive environments, such as retail markets, characterized by a growing heterogeneity of demand and the proliferation of new retail formats, cross-shopping behavior between stores and formats is becoming increasingly common. This process makes customer loyalty a key strategic challenge for retailers that want to consolidate their position within the market. To contribute to the analysis and comprehension of this reality, the authors propose and assess different objective indicators of store loyalty, store format loyalty, and intra-format store loyalty based on budget allocation. Specifically, they analyze the role of retail format in observable loyalty patterns in a market. Through an empirical analysis of grocery purchase patterns of a sample of 580 Spanish households, the authors find that diverse objective loyalty indicators based on budget allocations provide very similar information from a practical point of view. They also find that consumers' regular use of various formats (specifically, supermarkets, hypermarkets, and discount stores) for their purchases explain observed disloyalty better than does purchasing in several stores within these formats. The observed patterns reveal that retail formats define differentiated store profiles that relate to the benefits sought in different purchase situations.     

Interformat competition in the grocery retailing

In the last few years, we have seen significant changes in the Italian retail environment which suggest that the patterns of retailing competition are more complex than in the past. In order to expand their target market in a context of economic recession, retailers are implementing new strategies aimed to stimulate the switching between different store formats. As a result, store formats are getting similar and new "hybrid" formats are emerging.This paper investigates the interformat competition between grocery store formats in the Italian retail market in order to understand which formats are converging and which, otherwise, are maintaining their distinctiveness. Our findings show that the rivalry between store formats (interformat) is becoming more intense than the competition within store formats (intraformat). These results have significant implication on both retailers and trade marketing strategies.     

Child socialization practices: Implications for retailers in emerging markets

Considering the unprecedented growth in the active role of children in the modern market place the present paper attempts to understand the potential of kids as consumers in an emerging retail market. The exploratory study uses a quota sample of 136 urban Indian parents to assess their attitude towards parenting and child socialization along with their preferences for retail formats while buying across select children׳s product categories. The empirical evidences of the research established the active and positive role of the urban Indian parents in the child׳s consumer socialization process and acknowledge the growing status of a child as an influencer and independent buyer with respect to select product categories in the market. The study reiterates on the positive correlation between the child׳s age and the strength of his influence on family purchase decisions. The paper significantly contributes with its insights on contemporary consumers to aid retailers with relevant marketing knowledge pertaining to the market of children and their parents in emerging India.     

Retail store formats,competition and shopper behavior: A Systematic review

This study presents a systematic review of literature covering 178 articles relating to physical store-based grocery retail formats. The research questions for the review were based on drivers of consumer choice and response to marketing activities across store formats, competitive effects and conduct in the context of format evolution, and the interplay of retail formats with societal stakeholders and environmental context over time. The review reveals substantial evidence on drivers of shopper choice among formats including intrinsic household characteristics, time value factors, shopping goals and motivations, and actionable retailer factors such as location, assortment, pricing, promotion. The evidence is scarcer where such marketing activities are difficult to vary. There is limited consensus that inter-format competition is more intense than intra-format. The modernization of formats globally was found to change the way they compete and how consumers behave toward them. There is evidence of substantial impact of entry of new formats, but less guidance for incumbent retailers on how they should respond. Several gaps were identified, and research directions included a typology for format types, the role of technology, a call for more causal evidence, and deepening the empirical base for intra- versus inter-format competition and drivers of format choice.     

The impact of retail store format on the satisfaction-loyalty link: An empirical investigation

Maintaining and improving customer loyalty is an important strategic goal for businesses as competition has intensified in almost all sectors of the economy. Retailers, in particular, feel the need to invest in customer loyalty more than ever before as channels and store format alternatives available for consumers to shop at have proliferated. However, current research in marketing provides little guidance to retail managers about developing and sustaining shopper loyalty across different store formats. Toward filling this gap, the present research examines the shopper satisfaction-loyalty link in two different store formats (supermarkets and hypermarkets). Using data from surveys of 505 Spanish shoppers at both types of retail formats, we examined how shoppers' attitudinal and behavioral loyalty develop differently. Our results reveal important differences and offer directions for the pursuit of different strategies by supermarkets and hypermarkets. The specific strategies, and the implications of this research for theory and practice are discussed.     

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.     

Consumer Brand Marketing through Full- and Self-Service Channels in an Emerging Economy

A unique characteristic of emerging economies is the wide variety of dominant channel formats. We evaluate the influence of a brand's marketing mix on channel partners and consumer sales in both full and self-service channels in one emerging economy (Brazil). We use monthly stock-keeping-unit (SKU) level sales, and marketing mix data from the beverage category in southeastern Brazil spanning more than four years. In this study, we specify a panel vector autoregression framework with error decomposition to account for endogeneity between sales and marketing mix, cross-sectional heterogeneity among SKUs, seasonality, and the different aggregation of marketing mix elements across the channels. The results show that structural differences in these channels cause differences in the responses to some of the manufacturers' marketing mix elements. Package size variety, price and merchandising have a greater long-term effect on sales in self-service than in full-service channels. Brands' channel relationship programs support price increases in self-service channels without a corresponding decrease in sales. Distribution gains are important in both channels. In the full-service channel, package size variety has the highest long-term effect among all of the modeled marketing mix elements. Our study highlights that marketing mix strategies popular in the self-service dominant channels of the developed economies are not as effective in the full-service formats that remain important in emerging economies.     

Segmenting multichannel consumers across search,purchase and after-sales

While bricks-and-mortar stores and the Internet are dominant retailing channels, mobile and social media have rapidly emerged and challenge traditional retail models and consumer behavior. However, researchers have yet to account for how consumers integrate mobile and social channels throughout the various stages of the buying process. Using Latent-Class Cluster Analysis segmentation, we examine consumer behavior in store, Internet, mobile, and social media channels across the search, purchase and after-sales buying stages in the aggregate and specific to the clothing, holiday travel and consumer electronics categories. We find five multichannel consumer segments on the basis of perceived channel importance across the buying process, as well as psychographic and demographic characteristics. Interestingly, we find a polarization in perceived importance of mobile and social media channels, with two consumer segments rating mobile and social media channels as unimportant in the buying process. Furthermore, and compared to prior segmentations of multichannel consumer behavior, we do not find an aggregate store-focused segment. However, a store-focused segment exists in the context of buying clothing and represents 28.6 per cent of consumers. The findings show multichannel consumer preferences and behavior continues to evolve in line with new and emerging retailing channels. Further, this study confirms that there is no ‘one-size fits all’ approach to multichannel retailing.     

Consumer innovativeness: Impact on expectations,perceptions, and choice among retail formats

Individual differences in innovativeness may drive consumer expectations and perceptions regarding retail environments, influencing preferences for particular store formats. This research investigates the impact of consumer innovativeness on expectations for, and perceptions of, service design elements, including employee performance, process design, design of physical evidence, and reliability of the shopping experience. Findings indicate that the majority of consumers expect high performance along all dimensions and dislike surprising stores, specifically those they perceive as risky. Moreover, innovative consumers expect even higher levels of store attributes and in fact perceive stores differently than do less innovative consumers.     

Leveraging Information Across Categories

Companies are collecting increasing amounts of information about their customers. This effort is based on the assumption that more information is better and that this information can be leveraged to predict customers' behavior in a variety of situations and product categories. For example, information about a customer's purchase behavior in one category can be helpful in predicting his potential behavior in a related category, which in turn could help a firm in its cross-selling efforts. In this paper, we present a model to better understand and predict a consumer's purchases and preferences when we may have limited or no information about him in one or more product categories. Conceptually this involves leveraging information from purchases of other consumers in multiple categories as well as partial information (e.g., purchase in one of the categories) of the target consumer. Our approach builds on the pioneering work of (Rossi et al. (1996)) who demonstrate the value of purchase information in the context of a single product category. We present results from an extensive simulation as well as an application on scanner panel data. Our simulation shows many interesting and somewhat surprising results. Specifically, we find that compared to a single-category analysis, a cross-category analysis does not lead to any significant improvement in data likelihood in most cases. Therefore, the single-category analysis of (Rossi et al. (1996)) is even more powerful than previously thought. However, we also find that a cross-category analysis does improve parameter recovery in many situations as compared to a single-category analysis. It is in these conditions that retailers can use cross-category information to better implement micro marketing programs. We demonstrate the transfer of information across categories in an application of two grocery products—Breakfast Foods and Table Syrup. In spite of a reasonable correlation (0.21) in the price parameter across these two categories, our simulation guidelines predict very little benefit of cross-category analysis over single-category analysis. Our empirical results confirm this prediction.     

The Greydollarfella: An endangered species or a market opportunity?

This paper identifies an ignored and endangered species: the mature male shopper, who we have named the Greydollarfella. Based on current research and interviews, we describe this fellow and attempt to differentiate him from other consumer segments. The Greydollarfella, unlike younger men, appears not to like shopping and so is often ignored by retailers or excluded from the retail environment. We argue that the Greydollarfella should be included in, not sidelined from, retail and marketing considerations. He is much wealthier and less time-poor than younger men, and deserves a retail environment that suits his preferences and consumer requirements. We present some examples of how retailers are attending (and not attending) to the Greydollarfella. We conclude that Greydollarfella is not very well understood, is undervalued, and is often marginalised by retail marketing strategies. We believe he offers great value for marketers and retailers (both niche and mass) willing to take the time to understand his psyche, product and service needs, and views on the retail experience. Finally, we call for more attention to be paid to this segment.     

Exploring store format development and its influence on store image and store clientele – the case of IKEA’s development of an inner-city store format

Abstract

A changed technological landscape and radically changed consumer behavior are forcing retailers to rethink their business models, retail formats, and retail offerings. The global retailer IKEA is no exception in this development. Recently, the traditional IKEA format, which has been so successfully duplicated across the world over the years, has been complemented with other formats that are new and innovative for IKEA. Based on an empirical investigation of consumer perceptions of the store format development in Hamburg-Altona, Germany, the present study explores format development and its influence on store image and clientele, considering also the purpose of visiting IKEA and how this seems to have changed with the introduction of the new format. We also discuss the core aspects of the IKEA formats, and the fact that although some things have changed, others have stayed the same to preserve the IKEA image.     

A Bayesian multivariate Poisson regression model of cross-category store brand purchasing behavior

The availability of cross-category transaction data in the retailing industry has enabled the investigation of interdependence in consumer purchase behavior across product categories. In this paper, we develop a multivariate count model to uncover and predict the pattern of cross-category store brand purchasing behavior. The proposed multivariate Poisson regression model, which we estimate using a Bayesian approach, provides flexibility in capturing cross-category correlations for sparse multivariate purchase data associated with infrequently purchased categories or purchasing in retail outlets such as warehouse clubs. We compare the goodness-of-fit of the proposed Poisson regression model with alternate benchmark models using customer purchase records across five product categories from a national warehouse club and find that the proposed model provides a superior fit. We also carry out a profitability analysis to illustrate the use of the model in planning cross-promotions.
