Organizing Products with Complements versus Substitutes: Effects on Store Preferences as a Function of Effort and Assortment Perceptions

Retailers often organize at least part of their assortment by displaying complementary products from different product categories together (e.g., a pair of pants with a shirt) rather than grouping items by product type (e.g., a pair of pants with other pants). However, little is known about how retailers should choose between complement-based and substitute-based organizations. The present paper shows that consumers’ preferences for such store organizations are a function of the effort and assortment perceptions cued by these organizational formats. Holding the underlying assortment constant, complement-based organizations are always more effortful than substitute-based organizations. This difference in effort can create downward pressure on complement-based store choice. Moreover, the effects of organization format on assortment perception depend on whether consumers hold a hedonic or utilitarian focus. When consumers have a highly hedonic focus, complement-based based stores create more positive assortment perceptions than substitute-based stores. Such positive assortment perceptions can, in turn, raise complement-based store choice. However, as consumers’ utilitarian focus increases, substitute-based assortments are seen as both easier and more attractive, leading to a strong advantage in store choice. Our findings provide actionable guidance for retailers considering various store organizations and suggest opportunities for future research.     

The influence of in‐store personnel on online store value: An analogical transfer perspective

In today’s multichannel retail environment, consumers’ experiences in one channel influence their perceptions of another channel. Specifically, consumer evaluations of a firm’s online store have been found to be influenced by consumer interactions with the firm’s in‐store personnel. This paper is among the first to address this assumption and test it empirically. Drawing upon the analogical transfer paradigm, we propose hypotheses and accordingly model in‐store personnel’s competence and friendliness as determinants of online store usefulness, online store enjoyment, and online store value. Using consumer data collected from two Dutch multichannel retailers, we test this model with partial least squares modeling. The results provide clear support for the model and confirm that consumers may use characteristics of in‐store personnel as analogies when evaluating a firm’s online store. Implications for research and retail managers are discussed.     

The evolving role of hit and niche products in brick-and-mortar retail category assortment planning: A large-scale empirical investigation of U.S. consumer packaged goods

Long tail theory, the notion that the future of retailing could involve shifting product assortments to offer more product variety to precisely serve the unique needs of individual customers, has largely been proven true in the context of online distribution. However, it has been implicitly assumed that this theory does not apply to brick-and-mortar selling situations due to higher supply side inventory costs and higher demand side consumer search costs. Academics and practitioners alike have thus advocated for the use of Pareto rules to make category assortment planning decisions about product inventory breadth and depth in the brick-and-mortar channel. This research directly challenges this received wisdom by noting that the widespread prevalence and use of mobile technology is causing information flows to speed up for consumers even while performing traditional shopping tasks. Such information flows should theoretically favor the strategic importance of niche products in the long tail of the sales distribution. A large-scale empirical analysis of consumer packaged goods brick-and-mortar retailing data indicates that this alternative prediction is indeed true. This research contributes to a larger body of research as well that has documented how major environmental forces are shifting the nature of retail strategy, particularly in the brick-and-mortar channel.     

The Impact of the Multi-channel Retail Mix on Online Store Choice: Does Online Experience Matter?

More and more grocery retailers are becoming multi-channel retailers, as they are opening an online alternative next to their traditional offline supermarkets. While the number of multi-channel grocery shoppers is also expanding at a fast growth rate, there are still large differences in online shopping frequency, and as a result, in the levels of experience with buying in the online grocery channel. This study wants to (i) identify the underlying drivers of online store choice and (ii) explore if and how these drivers change when multi-channel shoppers gain online grocery shopping experience. We investigate this question with an online store choice model using purchase data of an extensive UK household panel over a two-year period, covering all multi-channel retailers in the grocery market. Our results show that multi-channel shoppers, at the start of online grocery shopping, tend to select the online store belonging to the same chain as their preferred offline store, especially when the online store is strongly integrated with the offline store in terms of assortment. When online grocery shopping experience increases, multi-channel shoppers’ focus shifts from a comparison within a chain across channels to a comparison across chains within the online channel, resulting in an increasing importance of online assortment attractiveness and online loyalty when choosing an online store.     

You can't buy what you can't see: Retailer practices to increase the green premium

Retailers are the gatekeepers between consumers and eco-friendly products. As such, they can influence green shopping behavior. The results of an eye-tracking experiment show that retailers can attract consumers’ visual attention and increase the green premium through various practices such as providing relevant information, orienting consumers inside the store, and offering an eco-friendly product assortment. Managerial implications are to use green-colored price tags to signal eco-friendly products, while avoiding greenwashing practices that can distract consumers from finding the eco-friendly products they look for.     

Shopping Benefits of Multichannel Assortment Integration and the Moderating Role of Retailer Type

To what extent should multichannel retailers integrate assortments across channels? Previous literature controversially discusses the question of which integration strategy is most successful but arguments are only conceptual, and no empirical assessment exists. This article presents a framework that (a) shows how customers’ perceived shopping benefits of variety, convenience, and reduced risk mediate the impact of multichannel assortment integration (full, asymmetrical, no) on patronage intentions and (b) differentiates the impact for retailer types based on substitutive, complementary, and independent assortment relations. Two large-scale experimental studies empirically investigate whether a dominant integration strategy exists in the context of full and simultaneous information (Study 1) and more uncertain and subsequent information accessibility (Study 2). We consistently find that full integration dominates no integration across assortment relations, but asymmetrical integration—the strategy that is most often realized by multichannel retailers—can have a detrimental impact for substitutive relations compared with no integration. Asymmetrical integration can be more beneficial than full integration for independent relations, while customer outcomes differ less for complementary relations. Researchers and managers can use our findings to understand how shopping benefits of variety, convenience, and reduced risk explain the different customer outcomes of multichannel assortment integration, depending on retailer type.     

Understanding Retail Managers’ Role in the Sales of Products and Services

This research investigates the influence of retail chain-level activities (e.g., district supervisor directives and policies) and store manager behaviors on the sale of physical products versus services. Using data gathered within a U.S.-based retail automotive parts chain, the authors discover that to sell services, especially in competitive environments, store managers should focus on sales planning and transformative leadership behaviors, which accentuate both the long-term planning horizon and the effects of managerial actions. In less competitive environments though, a more transactional approach (e.g., selling orientation) can be effective for selling services. Alternatively, to sell products, store managers’ selling effort appears to be the most important driver of success, and a transformative leadership approach may be detrimental when the retailer faces a high level of direct competition. In total, the findings suggest that corporate chain activities, such as the level and clarity of store managers’ goals and supervisor monitoring, influence store manager behaviors, which in turn affect the sale of physical products and services.     

Investigating the Effects of Daily Inventory Record Inaccuracy in Multichannel Retailing

Inventory record inaccuracy (IRI) challenges multichannel retailers in fulfilling both brick‐and‐mortar and direct channel demands from their distribution centers. The nature and damaging effects of IRI largely go unnoticed because retailers assume daily IRI remains stable over time within the replenishment cycle. While research shows that a high level of IRI is damaging, in reality the level of IRI can change every day. We posit that daily IRI variation increases the uncertainty in the system to negatively affect inventory and service levels. Our research uses data collected daily from a multichannel retailer to ground a discrete‐event simulation experiment. Going beyond testing just the level of IRI, we evaluate daily IRI variation's impact on operating performance. What we find in our empirical data challenges extant assumptions regarding the characteristics of IRI. In addition, our simulation results reveal that daily IRI variation has a paradoxical effect: it increases inventory levels while also decreasing service levels. Moreover, we also reveal that brick‐and‐mortar and direct channels are impacted differently. Our findings show that assumptions and practices that ignore daily IRI variation need revising. For managers, we demonstrate how periods of multiday counting help assess their daily IRI variation and indicate what the causes may be.     

Crosswise and reciprocal interdependencies within retailers’ multichannel structures

Understanding consumer behavior across channels is the fundamental basis for implementing successful multichannel retailing strategies. This study analyzes the crosswise and reciprocal relationships between offline and online brand beliefs, offline and online retail brand equity and consumers’ conative loyalty to a retailer in multichannel structures. The relationships are contextualized by investigating fashion and grocery retail sectors and different prior channel performances that are likely to affect the paths to loyalty across channels. To provide insight into these issues, two cross-sectional and two longitudinal models are employed. The results show that former brick-and-mortar retailers are able to significantly increase consumers’ loyalty to the firm by primarily designing offline (secondary online) attributes and beliefs. The results hold for retailers in both fashion and grocery retailing, however, with stronger effects in fashion, as well as for retailers with strong vs. weak prior channel performance. However, indirect effects indicate that online brand beliefs and offline retail brand equity are the central strategic levers for prior strong (vs. weak) retailers. Reciprocal relationships between online and offline retail brands underline important channel interdependencies. Managers thus need to take these crosswise and reciprocal interdependencies between channels into account when designing successful multichannel retailing systems. This study introduces the novel idea of simultaneous crosswise and reciprocal relationships within multichannel retail structures and shows that paths to loyalty vary for retailers in different retail sectors and retailers with strong vs. weak offline and online channel performances.

Strategic Assortment Decisions in Information-Intensive and Turbulent Environments

Recent trends in the environment have caused changes in consumers’ store patronage, price sensitivity, and need for variety. These changes have led retailers to reconsider some of their assortment options. Specifically, we discuss how they may have led some retailers to move from a single-format to a multiple-format channel portfolio, how they may have contributed to the growth of the discount format, and how they tend to influence the private-label portfolio of many retailers. We end by showing how these assortment changes may, in turn, have various welfare, logistical, and tactical implications.     

Why is Assortment Planning so Difficult for Retailers? A Framework and Research Agenda

When retailers conduct product assortment planning (PAP), they determine (1) The variety of merchandise, (2) The depth of merchandise, and (3) Service level or the amount of inventory to allocate to each stock-keeping unit (SKU). Despite longstanding recognition of its importance, no dominant PAP solution exists, and theoretical and decision support models address only some of the factors that complicate assortment planning. This article simultaneously addresses the variety, depth, and service level aspects of PAP to provide a more thorough understanding. A review of current academic literature and best trade practices identifies open questions and directions for further research and applications.     

The effects of multi-channel assortment integration on customer confusion

Abstract

The effects of assortment strategy on customer confusion have been discussed for singular channels in the past. However, multi-channel retailers also have to coordinate their assortment across channels. Recent literature has started to investigate which assortment integration strategy is most favourable for retailers, but theoretical and empirical research is still scarce. Until today, customer confusion has not been considered in this discussion. This article seeks to identify the impact of a retailer’s assortment integration on customer overload confusion, assortment perception and their consequences. In an experiment, we manipulate assortment integration internally (online and offline channel of the focal retailer; full and asymmetrical integration) and externally (online channel of the focal retailer and a competing online retailer; full, asymmetrical and no integration). The results indicate that both internal and external assortment integration have an impact on overload confusion and assortment perception. Asymmetrical internal integration induces less overload confusion in terms of its cognitive and affective components and leads to superior assortment perception. Full and asymmetrical external integration evoke less confusion with regard to its cognitive component. Eventually, overload has detrimental short- and long-term effects for the retailer. Multi-channel retailers should consider our results when implementing an assortment integration strategy.     

Perceptions of assortment variety: The effects of congruency between consumers’ internal and retailers’ external organization

This research shows that consumers’ perceptions of variety and satisfaction are dependent upon how the assortment is organized, both internally by the consumer and externally by the retailer. The results of three laboratory studies indicate that for familiar categories, congruency between a consumer's internal categorization structure and the external store layout leads to higher perceptions of variety and higher satisfaction with product choices, while for unfamiliar product categories, congruency between shopping goals and external structure leads to lower perceptions of variety but increased satisfaction with the store's assortment. However, if retailers institute external category filters congruent with consumers’ internal shopping goals that allow them to bypass products, consumers have both lower variety perceptions and satisfaction with the assortment offering.     

Dynamic assortment in the presence of brand heterogeneity

In this paper, we study the dynamic assortment planning problem in the presence of heterogeneous brands. Over a limited selling season, the retailer sells heterogeneous products from one store brand and one national brand. We use the nested multinomial logit (NMNL) framework to model consumer choice process, in which consumers choose first which brand to buy and then a product within that brand. We formulate this problem using the finite-horizon dynamic programming approach. Using available sales transaction data, we estimate the consumer choice behavior and empirically demonstrate existence of brand heterogeneity. Further, our results suggest that ignoring brand heterogeneity will make the retailer’s expected revenues significantly overestimated, and the potential revenue overestimation depends on initial inventories and prices of products of two brands. We finally show that the retailer will benefit from dynamic assortment optimization with the estimated consumer choice model.     

Identifying factors affecting consumers purchase incidence at retail trade shows

The purpose of this article is to examine variables influencing purchase incidences at retail trade shows. To this end, retailer and consumer related antecedent variables are proposed. The retailer related variables are represented by store environmental cues of sales staff services, store atmosphere and product assortment. The consumer related variables are represented by impulse buying tendency and perceived time pressure. Drawing on relevant literature, hypotheses are developed to link each of these variables to purchase incidence. Data were collected using questionnaire from shoppers (N=95) at a large retail trade show. The hypotheses were tested using partial least square path modeling. The findings indicate that consumers’ favorable evaluation of retailers’ sales staff services, store atmosphere and product assortment led to more purchase incidences. The findings about the consumer related variables indicate that impulse buying tendency led to more purchase incidences whereas perceived time pressure led to fewer purchase incidences. Drawing on these results, several implications for practice and research are suggested.     

Price matching and product differentiation strategies considering showrooming

Showrooming, a phenomenon in which customers use brick-and-mortar stores to assess products and then purchase them from online retailers (o-retailers) for lower prices, is considered a great threat to traditional retailers (t-retailers). To combat showrooming, many t-retailers have executed price matching which enables customers to pay o-retailers' lower prices for the identical product. To avoid direct competition with t-retailers who execute price matching, many o-retailers have begun to sell differentiated products from t-retailers, which weakens the information advantage to customers from practicing showrooming. Motivated by these observations, we construct a duopoly game, where a t-retailer and an o-retailer sell products in a same category, to study the profitabilities of product differentiation and price matching in the context of showrooming. The results show that in the scenario without price matching, the o-retailer is likely to benefit from product differentiation only when the o-retailer's differentiated product is more popular with customers than the t-retailer's product. However, in the price matching scenario, the o-retailer also has the opportunity to benefit from product differentiation when the o-retailer's differentiated product is less popular with customers than the t-retailer's product, and product differentiation can be a win-win strategy for the two retailers under certain conditions. Considering the o-retailer's product differentiation decision, the t-retailer is only likely to execute price matching if the non-digital attributes of the product category sold by two retailers are not very obvious.     

Crafting Integrated Multichannel Retailing Strategies

Multichannel retailing is the set of activities involved in selling merchandise or services to consumers through more than one channel. Multichannel retailers dominate today's retail landscape. While there are many benefits of operating multiple channels, these retailers also face many challenges. In this article, we discuss the key issues concerning multichannel retailing, including the motivations and constraints of going multichannel, the challenges of crafting multichannel retailing strategies and opportunities for creating synergies across channels, key retail mix decisions facing multichannel retailers, and the dynamics of multichannel retailing. We synthesize current knowledge drawn from the academic literature and industry practice, and discuss potential directions for future research.     

Consumer heterogeneity and online vs. offline retail spatial competition

This paper develops a game-theoretic spatial model featuring consumer heterogeneity in online vs. offline retailers’ spatial competition. We find that consumers’ browse-and-switch behavior intensifies the competition because both offline and online retailers’ price and profit decline when the behavior occurs, but it is not necessarily a threat to offline retailers especially when the product relates more closely to experience. We consider six equilibrium scenarios for different combinations of consumer behaviors when considering a hybrid retailer. The analysis taking consumer heterogeneity into consideration shows that the hybrid retailer operating both online and offline is not always the winner. Particularly, the business opportunity for the offline retailer lies in consumers’ willingness to pay in store, and whether the retailer launches an online store depends on the type of products and services provided.     

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.
