The mobile shopping revolution: Redefining the consumer decision process

The use of mobile devices by consumers and the accompanying response by retailers is rapidly revolutionizing the retail environment. In the past, retailers have focused primarily on the outcome (to purchase or not to purchase) of the consumer decision process, but now mobile technologies give retailers the opportunity to more actively influence the entire consumer decision-making processes. The increasing use of mobile devices by consumers makes shopping a continuous rather than discrete activity that requires retailers to engage with their customers at critical touch points of the decision process in order to provide a more customer-centric experience. This change in focus from the decision outcome to the decision process signifies an important paradigm shift for the retailing industry. After an extensive review of the literature, we identify four pillars that form the foundation for the mobile shopping revolution and represent the essential ways and means through which retailers can engage with consumers during the decision process. We also discuss the different areas in which the pillars can enable retailers to achieve a sustainable competitive advantage in the mobile shopping era.     

Does sustainability really matter to consumers? Assessing the importance of online shop and apparel product attributes

Although there is a shift in consumers' consumption behavior towards more sustainable patterns across a variety of different contexts, sustainable apparel has still not become a mainstream trend despite the textile industry's excessive usage of valuable resources. Albeit extant research found different potential barriers elucidating why consumers hesitate to purchase such apparel, it remains unclear whether sustainability really matters to consumers in a clothing context and further, which aspects are of relevance during consumers' purchase decision. We thus conducted two studies with four best-worst scaling experiments in which 4,350 online shoppers assessed the importance of both conventional and sustainable apparel attributes, as well as sustainable apparel attributes only, and the willingness to pay for sustainable product attributes. We further inquired the importance of conventional as well as sustainable online shop attributes. Our findings indicate that conventional apparel attributes such as fit and comfort, price-performance ratio, and quality are of higher relevance to consumers than sustainable attributes. The most important sustainable apparel attributes are the garment's durability, fair wages and working conditions, as well as an environmentally friendly production process. Consumers also indicated to prefer the latter three attributes to a 20% discount. Moreover, consumers demand less as well as sustainable packaging, free returns, and discount campaigns. Our findings reveal a gender gap regarding green consumerism with female respondents assessing most sustainable attributes as more important than male respondents do.     

Same but different - The effect of the unit of measure on the valuation of a unit price

Unit prices are a ubiquitous phenomenon. The respective legal norms leave a certain freedom of choice with regard to the reference unit. However, research on the impact of alternative measurement units on consumer behaviour is still in its infancy and its findings are inconclusive. Moreover, this influence has so far only been measured directly. Investigating the product category bottled beer (with its essential product attributes ‘brand’, ‘price’, ‘alcohol content’ and ‘size of packaging unit’), a Choice Based Conjoint experiment provides empirical evidence that a large (per 1 L) compared to a small (per 100 mL) size unit of measurement leads to a significant shift of importance towards the product attribute ‘price’ at the expense of the ‘brand’. In addition, consumers react more sensitively to price changes. At the strategic level, retailers can use these insights to sharpen their positioning through a suitable unit price measure. When making operational decisions, retailers should bear in mind that the reference unit influences the likelihood of purchase, the scope for price increases and the opportunities for up-selling.     

Examining impacts of negative reviews and purchase goals on consumer purchase decision

Extensive literature has studied the impact of positive online reviews on consumers’ purchase decisions. Research on the role of negative reviews in consumer price perception is heavily under-investigated. This study examines effects of negative reviews on consumer price perception and subsequent purchase behavior while considering the moderating effect of purchase goals. Results from two experiments show that the proportion of negative reviews has stronger negative impacts on purchase decision for consumers with a purchase goal than those without. This research contributes to growing knowledge about negative online reviews and consumer goal literature and offers practical implications for online retailers.     

The Impact of Online and Offline Information Sources on Automobile Choice Behavior

The Internet has significantly impacted the information search behavior of consumers. Many consumers regularly consult Internet sources for information on product categories, brands, manufacturers, and retailers, particularly when making a purchase decision about major durable goods. Automobiles are one example of such goods. The Internet has become a major source for information on automobile brands, attributes, and dealers. While much research has been done on the impact of the Internet on automobile information search behavior and search costs, there is limited work on the relationship between Internet use and the ultimate automobile choice. This type of relationship may have interesting managerial implications for both manufacturers of automobiles and firms that provide information on automobiles. This paper attempts to address this gap. It examines whether Internet use is associated with different choice patterns for automobiles. Using discrete choice analysis on automobile choice data, we explore whether there will be differences in the salience of specific information types for online versus offline consumers. We find that Internet users rely more on ratings while non-Internet users rely more on recommendations when making automobile choices. Our findings have several useful managerial implications for information provision, both online and offline.     

Perception of Risks and Preferences for Locally Grown Produce: A Marketing System Approach

In recent years, the “buy local” movement has escalated in popularity. This trend is redefining how value along the food chain is shared between producers, retailers, and consumers. A theoretical model was developed and used to evaluate how consumers formulate preferences for locally grown attributes, with an emphasis on consumers’ perceptions of food safety risk. Linkages between locally grown produce attributes, perceived macro outcomes, and value allocation to consumers are then examined using random utility discrete choice models. While results were mixed depending on frequency of purchasing locally grown produce, they do indicate that consumer preferences are driven by perceived food safety risk and other macro outcomes. For example, consumers who frequently purchase locally grown produce perceive these products to be environmentally friendly and to improve their quality of life.     

The Sales Velocity Effect on Retailing

In an increasingly crowded marketplace, retailers need innovative ways of promoting products to their consumers. E-commerce retailers have utilized to great effect lists of top ranked products to promote product sales; the higher the sales rank, the more likely consumers buy that product. This influence to buy, based on observing what others bought is known as observational learning (OL). Prior OL research assumed that OL arises from observing a static outcome, such as the current sales rank of a product. However, prior research on intertemporal choice showed that people prefer outcomes with increasing trends over stable or decreasing trends. This suggests that observing an increasing sales rank, denoted as sales velocity, would have a positive effect on purchase likelihood. We conducted three studies to test the sales velocity effect. Results show that sales velocity has a significant effect on likelihood of purchases, reversing even participant preferences for a product with a higher sales rank. This effect is consistent across four broad products tested. For researchers, by joining the two previously disparate branches of research in OL and intertemporal choice, we addressed a gap in OL research which previously ignored the velocity dimension of OL. For retailers, the study demonstrated the impact of the sales velocity metric on making choices, and thus they could use sales velocity data as a cost-effective marketing tool for specific products.     

The role of consumer knowledge,experience,and heterogeneity in fish consumption: Policy lessons from Japan

Fish supply worldwide has increased significantly in recent decades, driven by the growing demand for food in developing economies, especially Asia. Many developed countries, including Japan, have implemented health policies that promote fish consumption. Despite efforts to encourage consumers to purchase fish, Japan has not achieved satisfactory results due to competition from cheap livestock products. The purpose of this study is to understand how consumers compare fish to other protein sources and how different consumer attributes influence the purchase frequency of fish. We used factor analysis to create a perceptual map of consumers' evaluations concerning protein sources, and a Bayesian hierarchical model incorporating individual heterogeneity to model purchase frequency. Our results show that Japanese consumers place great importance on availability when evaluating protein sources, and that fish is considered less available than other livestock products. In addition, Japanese consumers still prefer wild fish to farmed fish in terms of quality. Individual consumer attributes, such as age, household structure, and eating habits, were found to influence the decision to purchase fish. Consumers’ first-hand fish-related experience is found to be an important determinant of fish consumption. However, the effect of their knowledge identified in the conventional model was not detected in the Bayesian model. These results suggest that experiences allowing consumers to feel closer to fish are more effective than exposure to excessive information campaigns. Using lessons from Japan, this research could aid policymakers and suppliers of fish products to fashion appropriate and effective strategies for encouraging greater fish consumption.     

Effects of Lightness‐Location Congruency on Consumers’ Purchase Decision‐Making

A considerable body of psychological and neuroscientific research has demonstrated the existence of robust sensory correspondences between various features, attributes, or dimensions of experience in different sensory modalities. Despite findings indicating the importance of sensory correspondences to human information processing, research on purchase decision‐making has not to date focused sufficiently on this phenomenon. The present study examines how the lightness of packaging colors, and the location of products on a display shelf interact to affect consumers’ purchase decision‐making via perceived visual heaviness. As predicted, a display with light (dark) colored products positioned in the upper (lower) shelf positions increases shoppers’ perceptual fluency and facilitates their visual search, thus leading to the suggestion that “light” (heavy) locations are most appropriate for light (dark) colored products. Moreover, the lightness‐location congruent display is shown to influence people's choice behavior positively as well. This research also demonstrates that when consumers consider the lightness (in terms of their weight) of the products, they are more likely to choose light (vs. dark) colored products located in the upper shelf positions. These results therefore demonstrate that consumers’ purchase decision‐making may be promoted by in‐store environments designed to be congruent with their sensory correspondences.     

Product Touch and Consumers’ Online and Offline Buying: The Role of Mental Representation

As offline retailers struggle to compete with online ones, the importance of a consumer’s ability to touch a product prior to purchase becomes important to study. Prior research has found inconsistent results on whether product touch facilitates consumers’ product-related decision making. Some studies report a positive effect, whereas others do not. The current research reconciles this inconsistency and draws retailing implications. Across three experiments, we show that the effect of product touch on consumers’ purchase intentions and willingness to pay for a product being evaluated is evident when consumers’ mental representation of the product is concrete, but not when abstract. We further show that perceived risk and perceived ownership simultaneously mediate this moderating effect of mental representation. Implications are drawn for both offline and online retailers.     

Is bigger better? How the scale effect influences green purchase intention: The case of washing machine

To stimulate purchase of green products, retailers and marketers need to know how to effectively present benefits of green products, specifically by numerical information. Accordingly, the current study provides useful insights on how to use numerical scale to influence consumer perceptions and green purchase intention. Data from a survey of 302 consumers show that green benefits expressed with an expanded scale (versus a contracted scale) increase perceived value of green products, producing in turn an increase in green purchase intention. Furthermore, low skepticism consumers perceive more value from benefits expressed in an expanded scale, but high skepticism consumers are less likely to be influenced by framing of the numerical scale due to heightened involvement. Significant moderation of consumer skepticism reveals its tempering effect on numerosity heuristic thinking in favor of the central processing route. These findings advance knowledge in the fields of numerosity heuristic, consumer decision and green consumption and provide managerial implications for retailers to formulate effective market segmentation strategies and enhance persuasiveness of numerical information to promote green purchase behavior.     

Consumer choice of retail shopping aids

This research investigates how consumer and product category attributes affect consumer interest in using various shopping aids. Research hypotheses were proposed based on a contingency framework of the relationship between consumer characteristics (i.e., purchase need, product knowledge, and brand preference heterogeneity) and shopping aid solutions (expanded selection, additional product information, personalization, and evaluative information). The findings demonstrated the importance of considering consumer characteristics when retailers design and provide shopping aids for consumers to facilitate purchase completion.     

Optimal checkout strategies for online retailers

Growth in online retailing has driven retailers to focus on optimizing the consumers’ shopping journey. One of the most important aspects of online shopping is the checkout process offered by the retailer. This paper focuses on factors influencing retailers’ choice of providing either a flexible checkout or a restricted checkout option to consumers. We define a checkout strategy as flexible when consumers can purchase items in their shopping cart either as a guest or by logging into their account. In contrast, with a restricted checkout strategy, the consumers must log in to the account to make purchases. With a game-theoretic model and duopolistic framework, the current study identifies conditions in which online retailers might adopt symmetric strategies and those in which two ex-ante symmetric retailers might prefer asymmetric strategies. The analysis suggests that the relative proportion of privacy-conscious (PC) vs. convenience-conscious consumers (CC), additional utility due to account registration, reduction in transaction cost, and additional revenue due to targetability are the crucial determinants of the strategies adopted by online retailers.Specifically, we show that retailers adopt a restricted checkout strategy when additional revenues due to targeted advertising are relatively high. Retailers adopt a flexible checkout strategy when the proportion of CC consumers and additional revenues due to targeted advertising are relatively lower. Furthermore, an asymmetric equilibrium may also exist when the proportion of CC consumers is relatively high and additional revenues due to targeted advertising are in the intermediate range. Our modeling framework provides a consumer demand-based (rather than cost-based) justification as a plausible explanation for why we observe ex-ante identical retailers offering distinct checkout strategies.     

Opportunities for active stock-out management in online stores: The impact of the stock-out policy on online stock-out reactions

This paper investigates the impact of an online retailer's stock-out policy on consumers’ category purchase and choice decisions. We investigate three different policies: (1) stock-outs are immediately visible and there are no replacement suggestions, (2) stock-outs are only visible after purchase attempts and (3) stock-outs are immediately visible but a replacement item is suggested. Results from an online grocery shopping experiment reveal that the adopted stock-out policy has a significant impact on both decisions. Making stock-outs not immediately visible creates confusion and intensifies the consumer's loss experience, thereby reducing the tendency to buy in the category. Suggesting a replacement item, in contrast, facilitates the substitution decision and slightly reduces the purchase cancellation rate. It also substantially increases the suggested item's choice probability. Yet, this effect disappears when higher-priced - suspicious - items are suggested. Overall, these results indicate that online grocery retailers have an interest in pursuing open and convenience-oriented stock-out policies.     

Understanding consumers’ multichannel choices across the different stages of the buying process

This article provides a more integrative approach toward channel choice than previous research by considering all stages of the buying process (search, purchase, and after-sales), and by taking channel attributes, experience, and spillover effects into account when examining consumers?? channel choice intentions. The authors show that such an integrative perspective is important as channel attributes, experience, and spillover matter for consumers?? channel choices in all stages of the buying process. Notably, the study stresses the importance of channel experience and spillover effects for explaining consumers?? channel choice intentions in the different stages of the buying process. Channel experience effects occur when using the channel increases the likelihood that the consumer will use the very same channel on the next occasion. Spillover effects result when the likelihood of using a channel in one stage of the buying process affects the likelihood of choosing that channel in another stage. The results show that both effects influence consumers?? channel choice intentions over and above channel attributes. Importantly, the model results strongly pledge for studying attribute, experience, and spillover effects simultaneously.     

A purchase decision support model considering consumer personalization about aspirations and risk attitudes

Ranking alternative products to help consumers make better purchase choices is a valuable research topic. Most previous decision support models cannot be well applied to heterogeneous consumers. This paper focuses on establishing a personalized interactive model to assist consumers make better buying decisions with less effort. For the alternative products provided by consumers, we collect online reviews and parameter configurations of alternative products and then obtain the fusing evaluative information. As consumers are dominated by bounded rationality, they only provide partially key attribute weights, based on which, we construct an optimizing model to obtain the optimal attribute weights of customers for products. Then, a satisfaction function is proposed by uniting aspiration levels and risk attitudes of consumers and a compensatory decision rules is established to rank and recommend the brands to consumers. Finally, practicability of this study is illustrated with a real car purchase case. Through the case study, it can be seen that the proposed decision support model generates a personalized list of alternatives based on consumer's own utility function about risk attitudes, aspiration levels, and preferences for product attributes, which further confirms that the proposed model can capture the personalized needs of consumers. Theoretical and managerial implications of this model as well as advantages are further illustrated.     

The effects of merchandise coordination and juxtaposition on consumers’ product evaluation and purchase intention in store-based retailing

Many retailers attempt to juxtapose and coordinate complementary products in their stores on the basis of key attributes because good coordination of complementary items can provide consumers with relevant information for their evaluation of individual products. In addition, the aesthetic appeal and the social impression that good coordination offers can be transferred to the products themselves. On the basis of these theories, the authors test the effects of merchandise coordination and juxtaposition (vs. separation) on consumer behavior using actual clothing items as stimuli in a laboratory setting. The authors find that coordination affects consumers’ evaluation of and purchase intention toward a target item only when the item is juxtaposed with a complementary item. This effect can be explained by the aesthetic response of consumers to and their social impression of a grouping of the items. Furthermore, in comparison with displaying the two items separately, juxtaposing them in a poorly coordinated manner appears to depress the target item's evaluation, though juxtaposing them in a well-coordinated manner does not seem to improve the evaluation.     

在线促销限制对消费者购买决策的影响研究——基于精细加工可能性视角

文章基于精细加工可能性理论探究了在线购物情景中不同促销限制类型（时间限制和数量限制）对消费者购买决策行为的影响。通过2（产品涉入度：高vs低）×2（限制类型：限时vs限量）的组间因子实验设计进行了实证研究,结果发现：在线促销情境下,促销限制对消费者购买决策的影响受到消费者产品涉入度的调节。当产品涉入度高时,消费者偏好时间限制促销,购买意向更高,感知控制感起了中介作用。当产品涉入度低时,偏好数量限制促销,购买意向更高,感知稀缺性起了中介作用。文章丰富了促销理论和消费者购买决策理论,同时为商家进行有效的在线促销提供了直接指导。     

Extending variety seeking to multi-sided platforms: Impact of new retailer listing

This study uses theories of variety seeking to examine how a new retailer listing on a multi-sided platform (MSP) affects consumer buying behavior. Using a unique dataset from an online MSP, we evaluate changes in purchase frequency with individual retailers after a new one is listed. Contrary to expectations, the results indicate that consumers increase their purchase frequency at existing retailers. Moreover, compared to consistency seekers, variety-seeking consumers show a higher positive effect as they buy even more. This result is observed for retailers in both competing and non-competing product categories. Finally, we discuss the theoretical contributions and implications for MSPs and retailers.     

Trustmarks: Strategies for exploiting their full potential in e-commerce

Internet-based commerce has undergone explosive growth over the past decade and is expected to keep growing. With the increasing popularity of online marketplaces, trust is seen as a key foundation for consumers’ willingness to purchase, in particular, from unknown sellers. While trust has been examined in various contexts, limited focus has been placed on the importance of displaying institutional trust assurances such as trustmarks on retailers’ websites. We conducted two studies into how the use of trustmarks impacts consumer trust, consumer risk perceptions, and, consequently, influences consumer purchase intentions. The results of the two studies suggest that the use of trustmarks increases consumer online trust and purchase intentions, as well as reducing their perceived risk. We use these results to inform managerial decision making in e-commerce, particularly for marketers and e-retailers. We provide three important managerial lessons to be learned from our insights. Our implications are important not only for mature e-commerce markets to create a competitive advantage but also for growing and emerging e-commerce markets, where new retailers are trying to establish trust among their consumers to increase market share.
