Effects of shopping information on consumers’ responses to comparative price claims

This article describes three studies that examine the effects of shopping information on consumers’ responses to comparative price claims in retail advertisements. Results of the studies show that 1) the opportunity to shop across retail stores reduces the effect of comparative price claims on consumers’ estimates of lowest price for a particular item, but has less impact on their estimates of the store’s regular price; 2) access to advertising from competing retailers has the same pattern of effects; and 3) across exposure to a series of ad claims, these effects generalize from estimates of specific item prices to judgments of the store’s general pricing. For branded shopping goods, the results show that comparative price claims may prove counterproductive for retail advertisers by leading consumers to believe that the store’s regular prices are high without convincing them that its sale prices are low.     

Consumers’ responses to price presentation formats in rebate advertisements

Although rebates offer an important and popular promotion tool in retailing, little research has investigated whether their presentation format can influence consumers’ evaluations of and purchase intentions toward products featured in rebate ads. Retailers generally use two different rebate ad formats: one that transparently shows both before- and after-rebate prices and the other that displays the after-rebate price in relatively large print and the before-rebate price in small print. Three experimental studies attempt to determine which format is more effective for eliciting favorable consumers’ responses, and the results show that the format emphasizing only after-rebate prices generally leads to lower purchase intentions because of the negative affect it elicits. Furthermore, the effect of a rebate presentation format is moderated by the rebate amount, consumers’ price knowledge, and rebate processing time. The results show that consumers’ responses to different rebate presentation formats entail both emotional responses and rational evaluations.     

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.     

The impact of external reference price on consumer price expectations

Comparative pricing practices are frequently used where actual product prices are accompanied by higher external reference prices. All types of stores, regular-price department stores as well as discount stores, use comparative price claims to frame price deals as attractive [Marketing Science 4 (1985) 199]. In this paper, a quadratic model is specified for the impact of external reference price (ERP) on consumer price expectations. Based on the research on communication discrepancy and advertising claim discrepancy, which in turn draw on assimilation-contrast, attribution, and prospect theories, we hypothesize a quadratic effect of external reference prices on consumer price expectations. An interactive, computer-controlled experiment using multiple levels of ERP is used to estimate the proposed model. As hypothesized, support for an inverted U-shape relationship is found between consumers’ updated price expectations and the difference between ERP and initial price expectations. That is, as the difference between ERP and subjects’ initial price expectations increases, subjects’ updated price expectations increase to a point and then start to decrease. We find that the fit of the quadratic model specification for the effect of external reference price on price expectations is noticeably superior to that of linear, logarithmic, square root, and S-shaped specifications. Finally, we provide implications of our results for both retail managers and for regulatory authorities alike.     

How Retailers’ Recommendation and Return Policies Alter Product Evaluations

This research investigates the interactive effects of retailers’ recommendations and return policies on consumers’ post-purchase evaluations of products which yield a mixed attribute performance. This article presents an account of the consumers’ post-purchase product evaluation process, in which counterfactual thinking plays a central role. Two studies show that consumers’ post-purchase evaluations of products, which yield a mixed attribute performance, tend to be more favorable under lenient return policies than under restricted return policies when retailers offer recommendations during the pre-purchase decision-making process, but more favorable under restricted return policies than under lenient return policies when retailers offer no recommendations.     

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.     

Group Buying: A Strategic Form of Consumer Collective

Existing literature on collective consumption focuses on passionate consumers of particular brands. This research examines group buying (GB), a multi-phase consumer collective activity, that creates value prior to, during and after the acquisition of products and services. Through a two-year, multi-sited, qualitative study, we examine both retailers’ and consumers’ motivations for participating in GB. GB is essentially a consumer collective that centers on consumer needs across brands, activities and lifestyles. This consumer collective is not initiated by brand affiliation or a consumption subculture, but by the need to discover desirable brands and obtain optimal products and services at favorable prices. Furthermore, GB empowers consumers to better protect their rights in an under-regulated market.     

Category-specific coupon proneness: The impact of individual characteristics and category-specific variables

In seeking to enhance the effectiveness of coupon promotions, researchers have long sought to identify “coupon prone” consumers. Previous measures of coupon proneness have not examined differences in coupon usage across product categories and have ignored the confounding effect of coupon attractiveness. An Item Response Theory (IRT)-based framework overcomes these limitations and yields category-specific estimates of propensity to redeem coupons that are independent of coupon attractiveness. The authors utilize an IRT-based model to estimate consumers’ category-specific propensities to redeem coupons for two product and two service categories, and investigate how coupon proneness varies across consumers and across categories as a function of individual characteristics and category-specific variables.The authors find that category-specific measures of propensity to redeem coupons achieve an average accuracy of 89 percent in predicting redemption intentions. Propensity to redeem coupons is also found to be related to category-specific brand loyalty and perceived coupon availability, as well as to individual characteristics such as general coupon proneness, value consciousness and price consciousness. These findings highlight the importance of studying coupon proneness at the category level and suggest that the IRT-based approach has considerable promise as a methodology for studying coupon usage. Using the approach proposed in this study, marketers can forecast the impact coupons are likely to have in their particular category, rather than relying on general coupon proneness measures to predict coupon redemption rates at the category level. The study's findings can also be used to identify categories and consumer segments where coupon promotions are likely to have a larger impact, and have important implications for managers planning joint couponing strategies.     

Understanding Money-Back Guarantees: Cognitive, Affective, and Behavioral Outcomes

Although money-back guarantees (MBGs) have a long tradition in marketing and retailing practice, a deeper understanding of how consumers value this instrument is still lacking. The results of two experimental studies show that in addition to cognitive effects, MBGs evoke a positive emotional response, thereby increasing consumers’ purchase intentions and willingness to pay a price premium. Moreover, MBGs positively affect consumers’ responses for search and experience goods, although for experience goods, MBGs should be designed with stricter return conditions as compared to MBGs for search goods. The results should help retail managers understand the consumer impact of MBGs, as well as assist them in pricing guaranteed items and designing effective MBGs according to the type of product.     

Retail environment and manufacturer competitive intensity

We study how the intensity of competition and the degree to which manufacturers enjoy market power depends on the retail environment in a given market. Past research has discussed the growing importance of retailers and the power they enjoy over manufacturers. Yet, the empirical literature to date has not determined which retail characteristics have the largest impact on competitive behavior.Our starting point is the estimation of a structural demand-and-supply model, where both consumers’ decisions and the strategic interactions between manufacturers and retailers are explicitly modeled. We identify the type of competitive behavior of manufacturers by measuring the deviation from a Bertrand-Nash equilibrium. This measure of competitive conduct is expressed as a function of key retail characteristics such as size of the retailer, its assortment depth, and category expertise.We illustrate the proposed approach using data for the ground coffee category in Germany. Our findings indicate that retail characteristics have indeed a significant effect on competitive intensity among upstream firms and on their ability to exercise market power. Hence, a manufacturer considering entry into a new market should not only take into account its competitors but also the specifics of the retail environment in this market.     

Situational price sensitivity: the role of consumption occasion, social context and income

Research on consumer reaction to price has been largely confined to examining consumers’ price information search, evaluation of price alternatives, and individual purchase behaviors without regard to situational influences. At the same time, consumption has often been dichotomized in terms of its functional-hedonic nature and has been examined with regard to social influence. Surprisingly, researchers have heretofore not examined the potential effect of the consumption occasion or social context on consumers’ price sensitivity. Further, research examining the effect of household resources on price sensitivity has produced mixed results. We argue that household income effects on price sensitivity are dependent upon the situation. This research addresses two key issues. First, we examine whether individuals are equally price-sensitive when purchasing products for functional (e.g., purchasing frozen vegetables or paper towels) versus hedonic (e.g., purchasing ice cream or cookies) consumption situations and whether social context (i.e., consuming the product alone or with others) influences price sensitivity. Second, we explore the interaction effects of household income and consumption context on price sensitivity. We examine these issues across a series of three studies, finding that consumers’ price sensitivity is in fact attenuated by both hedonic and social consumption situations and that income moderates these effects. Implications for researchers and practitioners are discussed.     

Usage-Based versus Measure-Based Unit Pricing: Is there a Better Index of Value?

In many product categories, unit prices facilitate price comparisons across brands and package sizes; this enables consumers to identify those products that provide the greatest value. However in other product categories, unit prices may be confusing. This is because there are two types of unit pricing, measure-based and usage-based. Measure-based unit prices are what the name implies; price is expressed in cents or dollars per unit of measure (e.g., ounce). Usage-based unit prices, on the other hand, are expressed in terms of cents or dollars per use (e.g., wash load or serving). The results of this study show that in two different product categories (i.e., laundry detergent and dry breakfast cereal), measure-based unit prices reduced consumers’ ability to identify higher value products, but when a usage-based unit price was provided, their ability to identify product value was increased. When provided with both a measure-based and a usage-based unit price, respondents did not perform as well as when they were provided only a usage-based unit price, additional evidence that the measure-based unit price hindered consumers’ comparisons. Finally, the presence of two potential moderators, education about the meaning of the two measures and having to rank order the options in the choice set in terms of value before choosing, did not eliminate these effects.     

Order Effect and Vendor Inspection in Online Comparison Shopping

In the context of online comparison shopping, the phenomenon of order effect and its impact has profound theoretical and practical significance, as many search engines and shopping portals offer paid placement and paid inclusion in search results. In this study, we investigate how order effects and other market competitive factors work together to attract consumers’ attention to online vendors, which is manifested by the time spent on collecting more vendor information, and the probability of a vendor being included in a consumer’s consideration set. We found that the effect of serial position of a vendor in a list is mediated by consumers’ attention which in turn affects the probability of the vendor being accepted.     

Consumer Responses to Vertical Service Line Extensions

Vertical line extensions extend an established brand to products at different price/quality points. In this study, we examine consumer evaluations of vertical service line extensions and the feedback effects of these extensions on the parent brand. Findings of two empirical studies in the hotel industry indicate that consumers perceive higher risks in step-up extensions than in step-down extensions, which consequently influences their evaluations of the extensions. This effect of extension direction is also found to be moderated by risk relievers such as service guarantee and consumers’ prior knowledge in the service category. Furthermore, we found that a parent brand receives more positive evaluations after the introduction of a step-up extension than that of a step-down extension.     

Effects of Consumers’ Efforts on Price and Promotion Fairness Perceptions

This research examines how consumers’ efforts as a nonmonetary sacrifice influence their price and promotion fairness perceptions in the context of price promotions. Multiple studies using different price promotion tactics demonstrate that consumers’ perceived level of effort to obtain a reduced price negatively influences their fairness perceptions when they deny the promoted price. Exploring the underlying mechanisms of this effect, we show that the amount of effort consumers exert to obtain a promoted price leads to their feeling of deservingness and entitlement. When the promoted price is denied, this feeling of entitlement is violated, causing unfairness perceptions to occur. The research demonstrates that, in addition to retailers’ actions such as price changes, consumers’ actions, in the form of their effort input, are also an important determinant of fairness perceptions.     

The influence of online product recommendations on consumers’ online choices

This study investigates consumers’ usage of online recommendation sources and their influence on online product choices. A 3 (websites) × 4 (recommendation sources) × 2 (products) online experiment was conducted with 487 subjects. Results indicate that subjects who consulted product recommendations selected recommended products twice as often as subjects who did not consult recommendations. The online recommendation source labeled “recommender system,” typical of the personalization possibilities offered by online retailing, was more influential than more traditional recommendation sources such as “human experts” and “other consumers”. The type of product also had a significant influence on the propensity to follow product recommendations. Theoretical and managerial implications of these findings are provided.     

Are temporally reframed prices really advantageous? A more detailed look at the processes triggered by temporally reframed prices

In this paper, we analyze effects of prices temporally reframed to a short period of time. We transfer a theoretical framework from a similar field of research to the context of temporally reframed prices. Based on this framework, we conduct a new empirical study. The results of the study show that temporally reframing prices leads to higher price attractiveness. However, this positive effect is overcompensated by negative effects of consumers’ feeling of being manipulated and of an increased perceived complexity of the price structure when temporally reframed prices are used instead of aggregate prices.     

Macro-economic determinants of consumer price knowledge: A meta-analysis of four decades of research

For the past four decades, dozens of researchers have studied consumer price knowledge, often with disagreements on the extent of consumer' ignorance about prices. While some of these disagreements have been attributed to research design variations among studies, no inquiry has yet been made on the role of the economic environment on consumer price knowledge. Nevertheless, environmental factors such as interest rates, unemployment, and economic growth may significantly influence consumers' knowledge of prices. Certain economic environments may therefore provide marketers with the ability to utilize pricing tactics which rely on limitations in consumers' knowledge of product prices. Using a meta-analytic framework, this paper synthesizes the results of 297 previous price knowledge studies to document the effects of inflation, unemployment, GDP growth, interest rates, country of study, and passage of time on consumer price knowledge. The meta-analysis results demonstrate that economic factors have considerable influence on explaining variations in consumer price knowledge. Managerial and public policy implications of the findings in light of turbulent economic environments are discussed.     

Low price guarantees as signals of lowest price: The moderating role of perceived price dispersion

This article presents two experimental studies examining the effects of a low price guarantee on consumers’ pre-purchase evaluations and behavioral intentions. The authors first examine how the effects of a low price guarantee are moderated by consumer perception of market price dispersion. The results show that low price guarantee effects are likely to be attenuated when consumers perceive market price dispersion for a product to be high. The second study shows that higher levels of penalty can help restore a low price guarantee's effectiveness. Specifically, a low price guarantee with progressively higher levels of penalty leads to incrementally more favorable effects on key consumer outcomes when perceived price dispersion is high. Interestingly, penalty level has no such incremental benefit in case of low perceived price dispersion. Theoretical and managerial implications of the authors’ findings, the limitations of the studies, and future research opportunities are discussed.     

Vulnerability to Low-Price Signals: An Experimental Study of the Effectiveness of Genuine and Deceptive Signals

Low-price guarantees help buyers make inferences about retailers’ prices. However, researchers are concerned that consumers might be vulnerable to relying on guarantees associated with high market prices. Furthermore, truly low-priced retailers that issue low-price guarantees might be vulnerable to consumers’ discounting of such guarantees. This article experimentally assesses these concerns and finds that the effects of adding a low-price guarantee to a low or high offer price on consumers’ pre-purchase perceptions depend on consumers’ confidence in their product category price knowledge and their decision involvement. The article explores the implications of the findings and provides directions for further research.
