The case of hierarchical loyalty programs Abstract: This research investigates how the benefits customers perceive from their participation in a store loyalty program (LP) impact on their satisfaction towards the program and on store loyalty. We explore the context of a hierarchical LP in the apparel industry. Our results show that perceived benefits and symbolic ones in particular are strong determinants of LP satisfaction and substantially drive store loyalty. We provide insights about the effectiveness of hierarchical LPs and suggest some recommendations in designing LPs in a more effective way.

The case of hierarchical loyalty programs Introduction Customer loyalty issues have been on the hedge for more than ten years now and they are still nowadays (see Lichtlé and Pichlon (2008) and Dorotic et al. (2012) for a thorough review). From a managerial perspective, defensive strategies such as retention, satisfaction and more broadly customer relationship or loyalty programs have demonstrated to be crucial to retailers or service providers and especially when competition is intense. From an academic point-ofview, researchers are interested in understanding not only the performance of these defensive strategies and in particular the performance of loyalty programs (referred to as LPs hereafter) but also in better grasping the underlying mechanisms that lead customers to be loyal to the store. Among the numerous customer relationship tools, loyalty card programs (referred to LCPs hereafter) are probably the most spread one among retail firms from various industries. Let us recall that retailers undertake LCPs to identify loyal customers and to reward them for their loyalty, to acquire knowledge about them and to (try to) develop a long lasting relationship with them. Though several studies have questioned the effectiveness of LPs (e.g., Dowling and Uncles, 1997; Meyer-Waarden and Benavent, 2003; Sharp and Sharp, 1997; Shugan, 2005), recent research shows evidence of the capacity of LPs to increase customer loyalty, at least behaviorally (e.g., Lewis, 2004; Liu, 2007; Meyer-Waarden, 2007). In addition, researchers have pointed out that the customer satisfaction towards LPs matters a lot. The design of LPs and in particular of LCPs seems to substantially impact customers’ perceived value of the program (Bridson et al., 2008; Yi and Jeon, 2006) and has a major impact on LP enrolment as well as its effectiveness (Demoulin and Zidda, 2008; 2009; Dorotic et al., 2012). 1 In the continuation of previous research, in particular the one of Mimouni-Chaabane and Volle (2010), this study looks at what are the drivers of customers’ satisfaction towards LPs. We investigate the benefits customers perceived from their participation in a store LP and we assess how the perceived benefits (i.e., utilitarian, hedonic and symbolic) impact on the satisfaction towards the program and finally on store loyalty. We develop and test a broad model of store loyalty including several dimensions of loyalty as well as moderating variables such as customer involvement in the product category. Though there have been several studies on how customer’s evaluation of the LP reward schemes and benefits impact loyalty variables, to the best our knowledge, no study has fully investigated the LP perceived benefits – LP satisfaction – store loyalty relationship. In addition, we explore the context of a hierarchical or multi-tier LP in the apparel industry in order to study a wide range of incentives and marketing actions. More and more retailers use hierarchical LPs, i.e. LPs that recognize different classes or tiers of customers according to their purchase behavior (e.g., bronze, silver and gold). Though the literature shows some starting interest in hierarchical LPs (e.g., Drèze and Nunes, 2009; Wagner et al., 2009), no study has evaluated their effectiveness yet. Our contribution is thus twofold. First of all, we provide an empirical test of the link between the perceived benefits, LP satisfaction and store loyalty and a better understanding of the role played by the different categories of benefits. Second, we provide some insights about the effectiveness of hierarchical LPs in enhancing LP satisfaction and store loyalty. From a managerial standpoint, we make some practical recommendations in designing LPs in a more effective way. 1. Background and hypotheses On the LP perceived benefits–LP satisfaction–store loyalty relationship According to previous research, the loyalty program membership per se does not necessarily 2 improve customers’ loyalty to the store. Past studies have shown that to be effective, LPs and the associated rewards must improve the perceived value of the company’s offer (Dowling and Uncles, 1997; O’Brien and Jones, 1995; Yi and Jeon, 2003) and that the customer satisfaction (Demoulin and Zidda, 2008) and loyalty (Yi and Leon, 2003) toward LPs are important drivers of store loyalty. Customers will enroll all the more if they perceive the value of the LP (Demoulin and Zidda, 2009). Value can be defined as “an interactive relativistic preference experience … characterizing a subject’s experience of interacting with some object. The object may be anything or event” (Holbrook and Corfman, 1985, p. 40). Value is thus associated with the benefits customers retrieve from their experience with an object or event, for instance shopping activities. The customers’ participation in a LP (e.g., collecting and redeeming points) can also be considered from an experiential perspective. Customers benefit in various ways from their experience with the LP. The benefits are not limited to monetary gains such as discounts, exclusive offers or gifts. LP members can also benefit from additional and preferential services (e.g., priority check-in in the airline industry), from invitations to special events (e.g., fashion shows in the apparel industry), from new product trials (e.g., make-up sessions in the HBC industry or new car drive in the automobile industry) or from exclusive product information (e.g., newsletters). Several categorizations of benefits have been proposed in the literature. Three broad categories of benefits emerge. The utilitarian benefits, which are primarily instrumental, functional and cognitive, are mostly related to the completion of the product/service acquisition task (Babin et al., 1994). The hedonic benefits are non-instrumental, experiential, emotional, and personally gratifying benefits (Arnold and Reynolds, 2003; Hirschman and Holbrook, 1982). Symbolic benefits define the third category. They are extrinsic advantages that products/services provide in relation to the need for personal expression, self-esteem, and social approval (Keller, 2003). 3 Very recently, Mimouni-Chaabane and Volle (2010) adapted to LPs the benefits associated with shopping experiences. They consider as utilitarian benefits all the monetary rewards LP members receive from their participation in the program (e.g., saving money through coupons, cash-back offers, shopping cost reductions). Regarding hedonic benefits, they retain exploration benefits (e.g., new product trial, information search) as well as entertainment benefits (e.g., unique experiences, pleasure associated with collecting and redeeming points). Finally, as symbolic benefits they consider recognition (e.g., have a special status, feel distinguished and better treated) as well as social benefits (e.g., belong to a group or community that shares the same values). A few studies have shown that shopping benefits positively impact on retail outcome variables (e.g., Babin et al., 1994; Jones et al., 2006). Relying on several theories such as the general attitude theory and environmental psychology, Jones et al. (2006) proved that perceived shopping value or benefits positively impact on store satisfaction, store attitudinal loyalty, store behavioral loyalty (i.e., repatronage intention) or word of mouth (WOM). In the context of LPs, Yi and Jeon (2003) showed that the perceived value of the LP reward scheme positively influence brand loyalty under the high customer involvement condition. In line with previous research and in particular with the theory of learning behavior (Rothschild and Gaidis, 1981), we thus hypothesize that LP perceived benefits will positively influence retail outcome variables such as behavioral and attitudinal store loyalty as well as word of mouth. Though for the clarity sake of this paper, we posit hereafter an overall positive impact, we of course expect differential effects across benefits. For instance, since hedonic and symbolic benefits are in essence more emotional benefits, we foresee a greater impact on WOM (i.e., a consequence of emotional responses to consumption situations according to Swan and Oliver (1989)) and on attitudinal loyalty than utilitarian benefits do. H1. Customers’ perception of the benefits provided by their participation in a LP –utilitarian 4 benefits (i.e., monetary savings), hedonic benefits (i.e., exploration and entertainment) and symbolic benefits (recognition and social)– increase their store loyalty (i.e., behavioral and attitudinal loyalty, word of mouth). Satisfaction and loyalty towards the LP have been shown to impact on brand (Yi and Jeon, 2006) and on store loyalty (Demoulin and Zidda, 2008). Previous research has also demonstrated that satisfaction and loyalty towards LPs are driven by the perceived value customers retrieve from their participation in the LP (Meyer-Waarden and Benavent, 2007; Mimouni-Chaabane and Volle, 2010) or by their evaluation of the LP reward scheme (Bridson et al., 2008; Meyer-Waarden, 2006; Yi and Jeon, 2003). When testing the nomological validity of the scales they developed, Mimouni-Chaabane and Volle (2010) found that utilitarian and hedonic benefits were mainly driving LP satisfaction but they did not found any impact for the symbolic benefits. We believe this might be due to the fact that 80% of their sample concern the grocery retail industry where symbolic benefits from participating in a LP are less likely to be found. In line with Yi and Jeon’s (2006) framework and findings, we thus hypothesize a direct route for the impact of LP perceived benefits and store loyalty and an indirect route throughout LP satisfaction. H2. The LP satisfaction mediates the LP perceived benefits–store loyalty relationship. To complete our model, we consider the moderating effect of the customer personal involvement towards the product category. Laaksonen (1999, p. 344) defines personal involvement as “the perceived personal importance of an object to an individual” and states that “involvement is supposed to be positively correlated with activities such as the extent of ongoing search information, money spent in that type of product category and frequency of product/service usage” (p. 345). According to past research, involvement may influence customers’ perception of LP rewards (e.g., Dowling and Uncles, 1997; Melancon et al., 2011; Meyer-Waarden, 2006; Yi and Jeon, 2003). For instance, Yi and Jeon (2003) shows that it 5 moderates the effect of the type and timing of rewards on the value perception. Under low involvement, the value perception of rewards impact on brand loyalty throughout program loyalty whereas under high involvement, the value perception of rewards positively influence brand loyalty both directly and indirectly via program loyalty. We thus foresee that the customer involvement will moderate the impact of LP perceived benefits on LP satisfaction as well as on store loyalty. Again, though we posit hereafter an overall impact, we expect differential effect of customer personal involvement, particularly regarding the link between entertainment/symbolic benefits and LP satisfaction. Entertainment benefits are not related to the company’s offer. They are rather linked to the point collection and redemption process. They will distract the involved customers from the company’s core offer. We thus expect that a greater involvement will decrease the positive effect of perceived entertainment benefits on LP satisfaction. Symbolic benefits are likely to have a higher effect on LP satisfaction for highly involved customers. Indeed, being fascinated by the product category, it is really important for them to share the brand values and to be recognized as special customers. H3. Customers’ involvement towards the product category moderates the relationship between LP perceived benefits and LP satisfaction. On the impact of LP hierarchies on the LP perceived benefits–LP satisfaction–store loyalty relationship A lack of differentiation between LPs is often pointed out as a potential reason for the observed ineffectiveness of LPs. Hierarchical LPs enable companies to offer non-linear incentives or rewards that are expected to increase customer loyalty more than linear ones. They thus enable these companies to better differentiate their LPs. Although the grocery retail industry has not been using this possibility yet, many other industries offer hierarchical LPs (e.g., airline, credit card, apparel, hotel, etc.). The usual bronze, silver, gold and sometimes platinum are used to refer to the different customer classes or tiers. The belonging to a higher 6 tier requires more spending from the customers but gives more valuable rewards. If hierarchical LPs allow retailer to achieve more differentiation by offering quantitatively more and qualitatively better rewards to higher-tier members, then the latter customers should perceive more benefits than customers in lower tiers. Drèze and Nunes (2009) investigated the relationship between the hierarchical structure of LPs (i.e., the hierarchy among customer classes) and consumers’ perception of status, that is the feeling of being socially recognized and of being superior in terms of prestige, power, or entitlement. They show using the theory of social comparison that the number of tiers (customer classes or segments) as well as the relative size of each tier have an impact on status perceptions. The greater the number of tiers (or the smaller the tier), the more special the customers feel. In other words, customers in the top tier feel superior if the size of their tier is small compared to other tiers and/or if there exists another immediate lower tier (in addition to the no-status tier). In addition, they show that a 3-tier LP works better than a 2-tier LP in enhancing status feeling. In a choice experiment, they also show that consumers prefer 3-tier LPs even though they do not qualify for upper tiers. Throughout communication and the reward scheme, companies enhance the higher-tier members’ feeling of status. They emphasize the exclusiveness and/or personalization of the rewards and benefits (e.g., VIP offers, newsletters and coupons) leading high-tier members to consider that they receive more than other customers and that what they receive is more valuable than what others get. In addition, given H2 and the expected positive relationship between LP perceived benefits and satisfaction and between LP satisfaction and store loyalty, higher-tier members should be more satisfied with the LP and finally more loyal to the store. We thus expect that: H4. In a hierarchical LP, higher-tier members perceive higher benefits than lower-tier members, are more satisfied with the LP and more loyal to the store than lower-tier members. 7 However, the LP perceived benefits–LP satisfaction relationship is unlikely to be similar across LP tiers. We indeed believe that the impact various LP benefits have on LP satisfaction will vary with tier membership. Higher-tier members may be more sensitive to symbolic benefits than their lower-tier counterparts. Given that they are part of an upper-level group, they might expect more attention from the retailer and express the desire to be recognized as good customers. Being part of a privileged group, close to the heart of the brand, they might better feel the benefits of belonging to the community. We thus hypothesize that: H5. Customers’ position in the LP hierarchy moderates the LP perceived benefits–LP satisfaction relationship. 2. Methodology 2.1. Survey To test our conceptual model, we surveyed the customers of a non-food retailer offering a hierarchical LP. We decided on ESPRIT which is active in the apparel industry and which provides its customers with a 3-tier LCP: a non-status tier (no LC associated), a basic or lower tier (associated with the red LC) and an upper tier (associated with the platinum LC). The LP offers rewards that can be classified into the five categories of benefits identified by Mimouni-Chaabane and Volle (2010). The platinum card holders receive more benefits than the red card holders. These additional benefits are VIP invitations to special events (i.e., monetary savings, exploration, recognition and social benefits), free alteration service (i.e., monetary benefit) and an exclusive hotline (i.e., recognition benefit). Red card holders access to the upper level once they spend more than 600 euros within a year. We surveyed 400 cardholders at the exit of 4 ESPRIT stores located in 3 Belgian cities (Brussels, Liège and Namur). The final sample includes 371 respondents from the two status tiers: 67% hold the red card (lower tier) and 33% hold the platinum one (higher tier). 87% are women. The age 8 distribution is as follows: 51%, 26.5%, 17% and 5.5% belong to the ‘18-26’, ‘27-40’, ‘41-55’ and ‘56 and more’ categories, respectively. 2.2 Measurement scales In order to measure the constructs, we used the usual 7-point agreement scale with a Frenchadaptation of the items proposed in the literature. We measured the five dimensions of the LP perceived benefits with 16 items (monetary saving (MS), exploration (EX), entertainment (EN), recognition (RE) and social (SO) benefits) and LP satisfaction (LPSAT) with 4 items (Mimouni-Chaabane and Volle, 2010). We measured the behavioral (BL) and attitudinal (AL) loyalty respectively with 4 and 3 items (Bruner et al., 2005; Bridson et al., 2008). The word of mouth (WOM) was measured with 4 items (Bridson et al., 2008). For the personal involvement in fashion clothing (INVOL), we adapted the items proposed by O’Cass (2001). The scales and items are presented in Appendix A. 3. Results The data were analyzed using SmartPLS version 2.0.M3 (Ringle et al., 2005) in two stages: the measurement model and the structural model. SmartPLS is a structural equation modeling technique that is recommended when the model is complex, the sample size is quite small or the assumptions of normality are not satisfied (Chin and Newstead, 1999). 3.1. Measurement model We tested the measurement model by performing a validity and reliability analysis for each measure of the structural model using SmartPLS. Appendix B shows the results as well as descriptive statistics about the constructs. All items loadings were satisfactory and the tvalues were significant. The composite reliabilities (CR) and coefficient alpha’s for each 9 construct are over the recommended 0.7 (Fornell and Larcker, 1981). The convergent validity was tested with the average variance extracted (AVE) and is higher than 0.5 for all constructs. The discriminant validity of each construct is supported by the square root of AVE being greater than the correlation of any pair of constructs (Fornell and Larcker, 1981). Consequently, the scales can be considered as reliable and valid. 3.2. Hypotheses testing Secondly, we used SmartPLS to test our hypotheses. We obtained the statistical significance of each path coefficient by using the bootstrapping resampling technique. In order to test H1 and H2, we look at the effect of perceived benefits on customers’ store loyalty mediated by LP satisfaction. We used the Baron and Kenny’s (1986) procedure revisited by Zhao et al. (2010) as well as Sobel’s test. Firstly, the effects of independent variables (perceived benefits) on the mediator (LPSAT) have been tested (see Table 1). All perceived benefits increase LPSAT except for recognition benefits. Secondly, we estimate the effect of the mediator (LPSAT) on the dependent variables (measures of store loyalty). All parameters presented in Table 2 are positive and significant. Thirdly, we test direct effects of perceived benefits on store loyalty measures. Only significant effects are presented in Table 3. Finally, we test mediations by using Sobel’s test. Table 4 presents the results of Sobel’s tests as well as total effects (a×b+c according to Baron and Kenny (1986)). Our results demonstrate that we have indirect-only mediations1 for the following links: EN LPSAT BL, MS LPSAT WOM, EN LPSAT WOM, EN LPSAT AL. Total effects for these indirect onlymediations are rather low. Total effects for complementary mediations (all the other mediations) are much higher. Mediations with highest total effects are SO LPSAT AL, 1 The mediation (Sobel’s test) is significant and the direct effect is not. 10 SO LPSAT WOM and EX LPSAT WOM. We have a direct-only nonmediation for the effect of recognition on behavioral loyalty (c=0.1847).

Direct effects of perceived benefits and LPTIER on store loyalty To test H3 and H5, we look at the moderating effects of the involvement with the product category and of membership levels. We only report significant moderations in Table 1. The results demonstrate that involvement significantly influences the relationship between entertainment and LP satisfaction (β=-0.119, p=0.0151). Indeed, the perceived entertainment has a lower impact on LP satisfaction for highly involved customers than for lowly involved customers. However, for highly involved customers, social benefits increase more the LP satisfaction than for weakly involved customers (β=-0.1485, p=0.0008). For higher tier members, recognition benefits enhance LP satisfaction (β=0.0938, p=0.0416) whereas 12 perceived social benefits do not increase their LP satisfaction (β=-0.1179, p=0.0353).

Sobel’s test results Finally, in order to test H4, we first look at the effect of LP tier membership on perceived benefits. We performed an analysis of variance to assess the significance of the mean differences between the lower tier (LPTIER=0) and the higher tier (LPTIER=1). Higher-tier members perceive higher monetary saving (p=0.0326), exploration (p=0.0238), entertainment (p=0.0003) and recognition benefits (p=0.0008). However, they do not perceive higher social 13 benefits (p=0.1073). Secondly, we test the effect of LP tiers on customer satisfaction with the program and on store loyalty. The results presented in Tables 1, 2 and 4 demonstrate that higher-tier customers are more satisfied with the LP (β=0.1197, p=0.0011) and more loyal to the store than lower-tier ones. We have complementary mediations through LP satisfaction for the three measures of customer loyalty. Indeed, mediations tested with the Sobel test (see Table 4) are significant as well as direct effects (βBL=0.2002, p=0.0000; βAL=0.1216, p=0.0007; βWOM=0.0840, p=0.0112 in Table 3). Except for social benefits, H4 is supported. 4. Conclusion Hierarchical LPs enable retailers to better reward their most loyal customers. As expected, higher-tier members perceive more benefits than their lower-tier counterparts, except for social benefits. Furthermore, perceived benefits increase customers’ satisfaction with the LP. However, recognition only improves the satisfaction of higher-tier members. Although higher-tier members receive more rewards because they spend more, we believe that the higher status provided by their belonging to the top-tier magnifies their perception of the benefits and their evaluation of the LP throughout the idiosyncratic fit heuristic effect suggested by Kivetz and Simonson (2003). Indeed, higher-tier members need to provide more efforts than other customers to obtain and maintain their status. Thus, receiving more increases their overall perceived value of the program because it better fits with the efforts they provide. This effect is even more important for those who mostly perceive the status feeling (higher perceived recognition benefits). For highly involved customers, social benefits have a higher influence on the LP satisfaction whereas entertainment benefits have a lower impact. Customers with a high involvement attach a greater value to the belonging to a group of people who share the brand’s value whereas customers with a lower involvement prefer to be entertained by the collection of 14 points. This is in line with past research (e.g., Meyer-Waarden, 2006; Yi and Jeon, 2003) which shows that highly involved customers tend to prefer direct (i.e., product categoryrelated rewards) than indirect (here, the pleasure obtained via point accumulation and redemption) rewards. Though greater social benefits increase LP satisfaction among lowertier members, they have quite no impact for higher-tier members. The collection of points leading to monetary savings and entertainment are the main determinants of LP satisfaction. These results are in line with Mimouni-Chaabane and Volle’s (2010) findings. However, if we consider the impact of the benefits on customers’ loyalty, the picture is very different. Indeed, symbolic benefits mostly enhance customers’ loyalty. Though it is not directly linked to attitudinal loyalty and word of mouth, recognition has a direct impact on behavioral loyalty. Social benefits are an important determinant of the three loyalty measures considered. Thus, symbolic benefits really matter in this particular industry. Regarding the determinants of behavioral and attitudinal loyalty, monetary and exploration benefits come after social benefits whereas exploration is the second most important determinant of word of mouth. Entertainment has a small effect on store loyalty, through an indirect-only mediation. Since they are the most important determinants of LP satisfaction, retailers should put forward the economic advantages of their LP as well as the entertainment linked to the point collection in order to increase their customers’ loyalty card usage. However, to retain their best customers and make them even more loyal, retailers should carefully design their LP in order to make their customers feel that they belong to a community of people who share the value of the brand and are close to it (social benefits). Retailers should for instance provide their customers with exclusive offers targeted to privileged customers, create special events such as brand’s anniversary to share the value of their brand (e.g., by reminding the origin of the brand) and offer special gifts to their best customers. They can also use monetary and exploration benefits to make their customers more behaviorally and attitudinally loyal. 15 Exploration can particularly be exploited to increase the word-of-mouth process. Indeed, receiving newsletters enables customers to discover the retailer’s offers and induces customers to talk to their family and friends about the brand and its new merchandise. Building on Drèze and Nunes (2009) as well as on Kivetz and Simonson’s (2003) recommendations, hierarchical LPs seem to be a tremendous way of increasing customers’ perception of benefits. The benefit-based categories of actions combined with a hierarchical LP thus offer retailers a true mean to enhance their customers’ loyalty and to differentiate their LP from competitors’ LPs. Regarding limitations, in order to make our results more generalizable, we believe this study should be undertaken in other industries where hierarchical LPs have been in operations for many years (e.g., airline and hotel industries). To complete the model, other mediators of the LP satisfaction – loyalty measures relationship should be investigated such as the customers’ satisfaction towards the store. PS. This is an ongoing research. The next version of the paper will include a theoretical refinement of our hypotheses as well as a more thoughtful discussion of our results.
