This study aims to examine the relative effectiveness of demand-related and supply-related explanations of the scarcity of a product, and specifically the extent to which decision context and individual factors moderate purchase intention in response to those explanations.

The first of two formal experiments examines the effects of the two kinds of scarcity on participants ' purchase intentions with respect to utilitarian and hedonic product types. The second tests for self-monitoring differences in participants ' relative susceptibility to scenarios characterizing scarcity as either demand-generated or supply-generated, when their decisions are either private or subject to third-party scrutiny.

Experiment 1 shows that participants shopping for a utilitarian product are more inclined to respond positively to what they understand to be demand-generated scarcity, and less inclined to do so if the scarcity was attributed to limited supply; whereas the converse holds true for a hedonic product. Experiment 2 shows that for high self-monitors, increased purchase intention was the outcome of matching the alleged reason for scarcity to the demands of the decision context; low self-monitors were ready to consider demand-scarce products regardless of whether they knew that their consumption decisions would be subject to third-party scrutiny or private.

The paper identifies contextual and individual factors that explain and predict the extent to which one type of scarcity appeal may be more effective than another in influencing consumers ' purchasing decisions.

The purpose of this paper is to examine the perception of luxuriousness as a novel underlying mechanism of the shelf-based scarcity effect by using both psychophysiological measures (Study 1) and self-reported measures (Study 2).

Two within-subject experimental designs were conducted to examine the effects of low, medium and high stock depletion levels (i.e. shelf-based scarcity) on consumer responses. In Study 1, facial expression analysis was used to examine consumers’ liking, and left frontal asymmetry brainwaves were used to examine consumers’ approach motivation as a proxy for purchase intention. Study 2 extended the findings with self-reported measures.

In Study 1, perceived product luxuriousness was found to underlie the shelf-based scarcity effect on facial expressions and left frontal asymmetry brainwaves after controlling for other previously proposed mediators (i.e. product popularity and quality). The shelf-based scarcity effect is only observed between low vs high stock levels, whereas moderate stock level depletion does not evoke the shelf-based scarcity effect. Study 2 used self-reported measures to replicate the effect of shelf-based scarcity on product luxuriousness. However, the findings demonstrated the limitation of self-reported measures to identify a significant spill-over effect of perceived luxuriousness to attitude.

Extending previous literature that relied heavily on self-reported measures, the current research used psychophysiological methods to uncover perceived luxuriousness as a novel underlying mechanism for the shelf-based scarcity effect. Thus, the findings are not only the first to provide psychophysiological evidence of the shelf-based scarcity effect but also to validate perceived luxuriousness as an underlying mechanism of the shelf-based scarcity effect.

The current findings suggest that the shelf-based scarcity effect is only evoked by high (instead of moderate) levels of stock depletion. The study also shows that shelf-based scarcity does not necessarily signal product popularity, but instead it may serve as a cue of product luxuriousness. Adding to other manipulations of retail spaces that elicit luxury perception (e.g. artwork, sensory delight and themed store atmospherics), this implies that businesses are able to use shelf-based scarcity as a cue to enhance or complement the luxury image or the perception of the brand or product.

The current research is the first study to use psychophysiological techniques to examine perceived luxuriousness as an underlying mechanism of shelf-based scarcity. It also demonstrates that self-report measures are not sensitive to such an effect in comparison to psychophysiological techniques, explaining why perceived luxuriousness has not been previously found to be an underlying mechanism of shelf-based scarcity.

The purpose of this paper is to understand the effect of store messiness and human crowding on shoppers' competitive behaviours, in-store hoarding and in-store hiding, through the mediating effect of perceived scarcity and perceived competition.

2 (store messiness: messy × tidy) × 2 (human crowding: high × low) between-subject factorial experiment was conducted online to manipulate retail store atmospheric factors. A total of 154 responses were collected through Amazon MTurk. The hypotheses were analysed using ANOVA and PROCESS (Hayes, 2013) procedure.

Results suggest that store messiness and human crowding within a fast-fashion store lead to perception of scarcity and competition that further affects competitive behaviours. When consumers experience store messiness, they are likely to hide merchandise in store, thus making it inaccessible for other consumers. Further, when they experience human crowding in the store, they feel that the products will be gone immediately so they have a tendency to hoard them.

This study examined the effects of scarcity perception by studying the case of fast-fashion retailers; generalizability needs to be established across different contexts.

Retailers by manipulating human crowding and store messiness can create a perception of scarcity in their stores, thus enhancing sales. However, they should also pay attention to deviant behaviours such as in-store hoarding and in-store hiding as these behaviours may decrease the store sales.

This research contributed to the retailing literature by finding a significant relationship between human crowding, store messiness and competitive behaviours through perceived scarcity and competition.

Live-streaming e-commerce (LSE) allows anchors to bring offline promotion skills to interact with consumers and persuade them to buy. However, how consumers respond to these communications remains unknown. This study examines the persuasive effect of different scarcity marketing messages on impulsive buying in the LSE context.

This study adopts scenario-based experimental methods and conducts two 2 quantity-based scarcity (supply-framed vs demand-framed)*2 time-based scarcity appeals (high vs low) between-subjects experiments to test the hypotheses.

The results indicate that supply-framed appeals are more effective in provoking consumers’ arousal and impulsive buying, but are moderated by time scarcity. Furthermore, emotional arousal only mediates the effects of quantity-based scarcity appeals on impulsive buying under high-level time scarcity conditions.

This study contributes to the e-commerce literature by comparing the persuasive effect of different scarcity messages in the LSE context. We broaden the scarcity marketing literature by testing the combined effect of quantity-based and time-based scarcity appeals. Finally, this study extends the application of the competitive arousal model.

Applying a middle-range theorizing to premises of signaling theory and the scarcity principle, this study aims to investigate the mechanisms and effects of different patterns of post-stockout disclosures that highlight the limited supply and high quality of a durable good on consumer satisfaction with the shopping experience and purchase intention, mediated by consumer perceived product scarcity.

The hypotheses are tested with two scenario-based experiments. The first experiment—a between-subjects design—explores the effect of post-stockout disclosures on consumers' perceived scarcity, satisfaction, and purchase intention. The second experiment – a within-subject design – examines the impact of time on consumer responses to stockouts.

Results indicate that perceived product scarcity mediates the relationship between post-stockout disclosures and consumer outcomes. Specifically, post-stockout disclosures present an indirect positive effect on consumer purchase intention, despite reducing satisfaction beyond the effects of the stockout. These results are consistent when disclosures are sent through multiple channels. Results also show that consumers' perceived scarcity and purchase intention decrease over time while dissatisfaction levels remain the same when stockouts persist.

Even though consumers will be dissatisfied upon experiencing a stockout, specific patterns of post-stockout disclosures can be a valuable strategy for consumer retention and lost sales prevention.

While recent consumer-centric supply chain management literature has investigated mitigation strategies of detrimental consumer response to stockouts, such as “save-the-sale” tactics and price discounts, the mechanisms and effects of different patterns of post-stockouts disclosures highlighting the limited supply and high quality of the product are yet to be investigated.

The purpose of this paper is to investigate the moderating roles of equality and scarcity on the impact of underdog brand positioning on consumer purchase intentions. Beyond testing the relationship between underdog brand positioning and purchase intentions (Study 1), the study examines how the equality perception affects consumer choices on underdog brands (Study 2) and how the reasons for product scarcity influence purchase intentions of consumers with prosocial orientations (Study 3).

A research model is developed, depicting the impact of underdog brand positioning on purchase intentions via social value orientations and scarcity types. The conceptual model is validated using moderation process modeling and data for which are collected through sets of structured questionnaires analyzed through PROCESS modeling in SPSS.

The findings support that compared with top dog brand positioning, underdog brand positioning has a greater impact on consumers’ purchase intentions, and consumers with prosocial orientations generate greater purchase intentions than consumers with proself orientations. In addition, the demand-caused product scarcity also moderates the relationship between underdog brand biography and purchase intentions.

The study contributes to the ongoing research on brand positioning by examining the associations between equality perception and purchase intentions in the context of underdog brand biography. The study also shows the value of demand-caused scarcity as a moderator of the underdog brand–purchase intention linkage.

The current research empirically aims to explore how displaying incompleteness influences the processing of product information and the number of products placed in the basket. This paper proposes a model of the effects of display incompleteness to analyze the influence of the processing of product information and product scarcity.

Four studies were conducted to test a model of the effects generated by the display incompleteness.

The results suggest that incomplete display increases the processing of product information and the number of products chosen. In addition, it supports that processing product information interacts with incomplete display to predict the number of display products placed in the basket. In this context, perceived scarcity cannot increase the effects of incomplete display on processing product information at low levels of perception. On the other hand, consumers will tend to process more information from incomplete displays when perceived scarcity gradually increases.

The empirical findings have some limitations. First, the authors’ experiments do not define whether scarcity was caused due to excessive demand or restricted supply. Second, the studies do not analyze the perceived exclusivity of the product in short supply. Finally, the studies did not indicate the differences between display incompleteness that showed variety and category scarcity.

The findings demonstrate that one of the ways to get customers' attention would be to have an efficient strategy for displaying incompleteness. Many managers believe the lack of products on display is an inventory management problem. However, the studies show that this can help increase product sales.

This research contributes to developing better metrics to understand the processing of product information in display incompleteness. Overall, the studies have demonstrated the value of measuring visual attention as an expression of processing product information to understand better how people visually process display incompleteness and its effects on consumption responses.

Experiential stores offer potential for emotional brand-consumer connections and word-of-mouth (WoM) generation. Past research links the lifecycle of such stores with perceived novelty, a defining characteristic that has not received sufficient recognition. Scarce products are identified as a promising strategy to enhance novelty perceptions. Additionally, the authors differentiate between electronic and interpersonal WoM, and consider need for uniqueness (NFU) as a relevant personality variable.

This study encompasses three experiments that seek to shed light on suggested relationships. The first two experiments explore the interplay between scarcity, perceived novelty, and WoM. Moving forward, the third study delves deeper into the matter, scrutinizing the conditions under which scarce products manifest their utility in experiential stores.

The findings indicate that incorporating scarce products can rejuvenate the novelty aspect of experiential stores and promote positive WoM outcomes. Additionally, including NFU as a personality variable presents a communication dilemma, as high NFU individuals tend to engage more in electronic WoM but less in interpersonal WoM. However, this relationship is contingent on circumstances, with high NFU individuals showing a greater inclination towards interpersonal WoM when the probability of being imitated is low.

This study offers practical guidance for brand managers aiming to sustain the appeal and success of their experiential stores, as well as for commercial real estate managers seeking to revitalize vacant spaces in the post-COVID-19 era.

This pioneering study investigates the role of perceived novelty and scarce products in experiential stores, aiming to identify optimal conditions for favorable consumer responses. It also contributes to research on the forward spillover effect and underscores the importance of interpersonal proximity in WoM investigations.

Intangible cultural heritage products (ICHP) in this paper refer to the products made with handicrafts listed as intangible cultural heritage. The purpose of this paper is to examine the effects of consumer cultural identity and consumer knowledge on purchase intentions of ICHP, as well as the role of the perceived scarcity for such effects.

Three between-participants experiments were conducted to investigate the effect of cultural identity on purchase intention of ICHP and the underlying mechanism of the effect.

The results show that cultural identity has a positive influence on ICHP purchase intention, and this effect is stronger for consumers with higher level of consumer knowledge. Furthermore, perceived scarcity underlies such effect, but the scarcity account holds only for handmade ICHP, not for machine-manufactured products.

The current research suggests that ICHP should remain handmade to preserve their scarcity as a distinctive feature. Additionally, business practitioners handling ICHP should target consumers of high cultural identity, and/or provide iconic cues to activate their cultural identity situationally. Furthermore, it highlights the importance of consumer education programs about ICHP-related knowledge in enhancing the cultural identity effect.

This paper explores systematically the conditions and process of consumers' responses toward ICHP for the first time. Besides, it builds on accessibility-diagnosticity framework and provides novel knowledge about the functioning of consumer cultural identity. It also enriches our understanding of perceived scarcity from the supply side.

This paper investigates the impact of framing through the use of a vague scarcity restriction (“while stocks last”) on consumers' perception of promotional offers involving different claim formats (tensile price claim such as “save up to 60 percent” versus non‐tensile price claim such as “save 60 percent”) and different amount of price discounts. The findings show that framing the sales offer with such a vague scarcity restriction and using a tensile claims format improve the consumers' perceived informational value of the offer, only if exaggerated price discounts are involved. This study also confirms earlier studies' findings on the effects of exaggerated price discounts and tensile claims on consumers' perceived savings and information value of sales promotional offers. Managerial implications are discussed.
