Quality-adjusted price comparison of non-homogeneous products across Internet retailers

This study compares prices offered by multiple Internet retailers. This task is challenging because e-tailers cannot present their entire assortments to each consumer. Therefore, the quality of the product assortments presented by different e-tailers to each consumer is not directly comparable on an item-by-item basis, resulting in non-homogeneous offerings across retailers. We further consider the interaction between retailers (product information presentation format) and consumers (product information search strategies), which makes price comparisons among the retailers even more non-homogeneous. To grapple with this quality-adjusted price comparison problem for non-homogeneous products, we use a stochastic-frontier hedonic-price regression model to find the “lowest” theoretical price for a product given its characteristics. We then assess the price efficiency of the product as the ratio between this lowest price and the offered market price. This framework allows for the comparison of retailers in their ability to offer the “best deals” even when their actual assortments are not directly comparable in quality. Moreover, this framework provides Internet retailers with a relative measure of price efficiency. This helps them understand when and where they offer competitive prices to consumers. We illustrate our approach empirically in a comparison of price efficiency among three major Internet travel agents on a sample of posted itineraries and airfares. Furthermore, we demonstrate that the price efficiency of an Internet travel agent depends on the format of its website and on consumers' search strategies.     

Price fairness perceptions and customer loyalty in a retail context

Loyalty and fairness are major research topics in the marketing literature. However, research examining how customer loyalty and fairness perceptions affect each other is lacking. This study examines these two topics in the context of a retailer increasing its prices, develops hypotheses, and tests these hypotheses using an experimental design approach. Results indicate that loyalty has a positive effect on fairness perceptions when price increases are low, though no such effect is found when price increases are high. Also, justifiable reasons for price increases lead to increased fairness perceptions when price increases are low, but any reason offered when price increases are high increases fairness perceptions. Whether distributive or procedural fairness influences post customer loyalty in the presence of price increases is dependent on both the level of the price increase and the reason offered for the price increase. This research provides implications for retailers and directions for future research.     

Price-matching guarantees in dual channels

Many retailers offer price-matching guarantees (PMGs) whereby they promise their customers that any lower price offered by competition for an identical product will be matched. Suppliers sometimes also offer PMGs to consumers in their direct channels. However, the extant literature on PMGs focuses on retailers and is silent on the role of upper stream chain members. We contribute to the literature by identifying the implications of PMGs in a dual distribution channel in which a supplier reaches consumers via a direct channel in addition to the retail channel. We show that the presence of PMGs in a dual channel hinges on supplier’s strategic ability, or lack thereof, to adjust its wholesale price in relation to the guarantee. Specifically, a PMG fails to prevail at equilibrium when the supplier is capable of strategically adjusting its wholesale price - but may prevail at equilibrium otherwise. The main reason is that the supplier can manage the competition between the retail channel and the direct channel through its wholesale price decision, and offering a PMG limits this ability. On the other hand, offering a PMG can be a beneficial strategy for the supplier when the supplier cannot adjust its wholesale price; for instance in a retail dominant chain where the retailer dictates the transfer price. In a retail dominant chain, if the direct and retail channels are perceived to be similar in quality and service offerings, then both channel members benefit from offering a PMG because it softens the intensity of price competition. On the other hand, when the two channels are sufficiently differentiated in quality and service offerings, then retail managers should be cautious and avoid offering the guarantee if their channel is in a superior position in terms of perceived quality.     

Social status and country‐of‐origin preferences

This paper explores consumers' attitudes towards products of foreign origin according to consumer social status, particularly when purchases come from countries that have a low‐cost/low quality image. The research question is: for an identical good (same manufacturer, same brand), do consumers belonging to lower social classes ask for a larger price discount than higher social status consumers when they are offered the opportunity to switch from a country of manufacture whose quality image is well established, to a country of manufacture, the image of which is more uncertain (e.g. South Korea)? A structural equations model is used to highlight the fact that social status has only an indirect influence on the discounts for shifting to lower‐image countries. The relatively weak image of Korean products (at least against Germany and Japan) tends to result in higher price rebates asked for the Korean manufacturing origin. But lower social status consumers evaluate Korea more positively as a country‐of‐origin. The normative recommendation for the advertising strategy of “cheap” origins' goods in highly developed markets would be to put emphasis on quality rather than price, especially when modest consumers and lower classes are explicitly targeted.     

Consumer evaluations of different promotion types and price presentations: the moderating role of promotional benefit level

The effects of promotion type (i.e., price discounts and bonus packs) and price presentation (i.e., dollars and percentages) across promotional benefit levels were investigated in three experimental studies. The results suggest, for the products considered, that price discounts and bonus packs were valued similarly for both low and moderate promotional benefit levels, while price discounts were preferred when high promotional benefit levels were employed. Additionally, promotions presented in percentage terms were preferred when the benefit level was high. The implications of these results for retailers and manufacturers are that percentage price presentations should be used when large discounts are being offered. Furthermore, it appears that bonus packs are a viable alternative to price discounts when promotion levels are small or moderate since they have less of a deleterious effect on the brand.     

Product quality,attributes, and brand name as determinants of price: The case of consumer electronics

This paper proposes and illustrates an approach to measuring one aspect of brand equity, viewed as a price premium and defined as the increment that a brand name contributes to the price of a product above and beyond that justified by its quality (where quality is determined by an assessment of the relevant attributes, features, or characteristics). Two illustrative studies apply the proposed measure to consumer-electronics products found in home-theater or audio-video entertainment centers. Study 1 uses data presented byConsumer Reports to regress market price on overall quality and on dummy variables coded to represent brand names. Here, the results for home-theater products suggest a conspicuous absence of incremental brand-name effects. Study 2 generalizes this result by analyzing data for various electronic products offered by theCrutchfield Catalog. Across six product categories, when controlling for differences in an attributes-based index of product quality, a significant brand-related price premium appears to occur only for Carver. This finding again casts doubt on the importance of brand equity in the market for consumer electronics.The author gratefully acknowledge the support of the Columbia Business School's Faculty Research Fund.     

The Economic Significance of User-Generated Feedback

This paper examines the impact of user-generated feedback on price at a price comparison site or shopbot. It employs a modified hedonic price function to explore the use made by current potential consumers of the experience of past actual consumers in evaluating quality attributes that were not observable when the product was initially launched on to the market. Using a database of daily observations on 211 digital cameras traded on NexTag.com, we find that the product’s star rating, reflecting all the available individual assessments of the product, has a significant negative impact on the discount on the manufacturer’s recommended selling price at which the product is offered.     

An experimental test of brand insulation against competitor attacks: Effects of consumer heterogeneity and residual desire

Price discounts generally move consumers from lower‐quality brands to higher‐quality brands more than from higher‐quality brands to lower‐quality brands. This asymmetry can reverse, however, to favor the lower‐quality brand when improvements are made to product quality. Whether such variations exist when the goal is to retain rather than steal customers remains untested and constitutes the focus of this study. Experimental results indicate that customer retention strategies tend to favor higher‐quality brands. Higherquality brands are able to retain customers by matching the form of the lower‐quality brand's attack (price reduction or quality improvement). For lower‐quality brands, matching is effective only in the case of a price attack by a higher‐quality brand. Furthermore, higher‐quality brands are able to effectively retain customers with price reductions that are smaller than the discount offered by a lower‐quality competitor, whereas lower‐quality brands must match the magnitude of a discount by a higher‐quality brand to retain customers. The findings suggest that differences in customer retention across quality levels arise from (1) heterogeneity among consumers of different quality levels in the relative weightings of price and quality, and (2) switching decisions based on reasons that are biased toward continuing to purchase, or moving to, higher quality products. © 2008 Wiley Periodicals, Inc.     

Fee or free? How much to add on for an add-on

Sellers often provide complimentary “no extra charge” add-ons (e.g., free Internet connection) to consumers who buy their primary products (e.g., a hotel stay), but recently add-ons that used to be free are offered for a fee. The conventional wisdom is that unadvertised add-ons for high fees help competitors increase profits that are competed away by advertising low prices for the basic products. This theory cannot explain why complimentary add-ons are still offered by some sellers. We show that providing complimentary add-ons can be profitable for sellers with monopoly power under certain demand conditions. If these demand conditions are not met, it is optimal to charge a supplementary fee for the add-on. We also show how pricing policy can be designed to selectively target or deter different consumer segments from purchasing the add-on to boost sellers’ profits, providing a strategic role for selling add-ons at either below-cost or at exorbitantly high prices. Yet such behavior may have repercussions for economic welfare when it results in socially inefficient giveaways when consumers would be better served with a lower price on the basic product without the add-on or, with the other extreme, when it results in excessively high prices for an add-on that restricts sales and leads to its under-provision from a societal perspective. The paper also provides managerial insights on the design and use of add-ons.     

Effects of sales promotion type and promotion depth on consumer perceptions: the moderating role of retailer reputation

This study uses a between-subjects experimental design to test the effect of two sales promotion formats (coupon versus markdown) with either high and low face values on consumer attitudes toward the deal, perceived product quality, and purchase intentions. The reputation of the retailer offering the deal is predicted to moderate the relationship between the promotional offer and consumer responses. Consumers perceive product quality to be higher when offered a high value coupon vs. markdown but there is no significant difference in perceived quality across promotion types when the promotion face value is low. When a deep price discount is offered by a retailer with a negative reputation, however, consumers have more favorable attitudes toward the deal and higher purchase intentions when provided with a markdown vs. coupon. Conversely, a high value coupon elicits more favorable evaluations than a markdown when the retailer has a positive reputation. When the value of the promotion is low and the retailer has a positive reputation, consumers have more positive deal attitudes and purchase intentions when offered a markdown vs. coupon. There is no significant difference in the effects of promotion type when the retailer has a negative reputation. The findings therefore establish retailer reputation as an important moderator of sales promotions effectiveness. This research is limited by the use of a single product category and a student sample. Process measures are also needed to validate the proposed theoretical conceptualization. The results provide managers insight into the type and value of the sales promotion to offer based on consumer perceptions of the retailer's reputation in the market.     

Retail price discount depth and perceived quality uncertainty

This study analyzes the impact of retail price discount depth on consumer perception of quality uncertainty and its implications. While the extant research finds a negative relationship between perceived mean quality (indicated by the mean of quality perception) and price discount, we suggest an inverted-U-shaped relationship between perceived quality uncertainty (indicated by the variance of quality perception) and price discount. The underlying mechanism for this phenomenon is that consumer attribution of price promotion varies by discount depth. Specifically, when provided with a moderate discount (compared with a low or high discount), consumers cannot ascertain whether the discount is related to product quality; thus, they perceive a higher level of quality uncertainty and correspondingly rely more on other cues, such as country of origin and product popularity information, to make inferences about quality. Those findings have implications for setting the depth of retail price discounts and providing product quality-related information in the context of price promotion.     

Price Consciousness and Purchase Intentions for New Food Products: The Moderating Effect of Product Category Knowledge when Price Is Unknown

This study examines the degree to which consumers' price consciousness affects their purchase intentions for a newly introduced product when the price of the product is unknown. Based on data from 186 consumers exposed to a new product offering, the results show that price consciousness indeed has a negative effect on purchase intentions, but only for consumers with a high level of product category knowledge. Although perceived risk and perceived value are significantly related to purchase intentions in general, price consciousness seems to affect only those consumers who make inferences about price based on their knowledge of the product category. Both theoretical and managerial implications of the findings are offered.     

Plausible versus implausible tensile price claim: Selective accessibility model approach

Retailers frequently use exaggerated price discount advertisements with a tensile price claim (TPC; e.g., “Save up to 70%”) to attract consumers because they expect that once consumers enter a store, they will purchase low‐ or medium‐discounted products. Drawing on the selective accessibility model, this study investigated the way in which an implausibly high maximum level of savings stated in a TPC influences consumers’ expected price discount (EPD) and perceptions of actual price discounts across different types of TPCs (i.e., TPC stating a maximum level and TPC stating a range of savings). This study also investigated two situations in which consumers have previous knowledge of a product’s price discount versus when they have less or no knowledge of the discount. For both conditions, a single‐anchor TPC (i.e., “Save up to Y%”) that stated an implausible maximum level of savings led to a higher EPD and lower perceptions of the deal (i.e., perceived savings, price fairness, and perceived value) with respect to the actual price discount than did a TPC with a plausible maximum level of savings. In contrast, when the TPC stated two anchors (i.e., “Save X–Y%”) and consumers had knowledge of the price discount, their EPDs assimilated only toward the plausible anchor (X), and ignored the implausibly high maximum price discount (Y), resulting in a lower EPD and higher perceptions of the deal of the actual price discounts than a TPC that stated a plausibly high maximum level of savings. In contrast, when consumers had no knowledge of the price discount, their EPDs only adjusted toward the more plausible anchor (X), regardless of whether they perceived the maximum anchor as plausible or implausible. Thus, there was no difference in consumers’ perceptions of “Save X–Y%” between implausibly and plausibly high Y%.     

Effects of the Price of Tax Preparation Services and the CPA Credential on the Perception of Service Quality

This paper reports the results of a study that examined two areas of interest in marketing accounting services for fax preparation. First, the question of whether the price charged by an accounting firm has an impact on the perceived quality of the tax preparation service is explored. Second, the effect of the CPA credential on the expected quality of the service provided is examined. The managerial implications of the findings are discussed for organizations with and without the CPA credential and guidelines are offered for analysis of the quality of the accounting service provided.     

De-targeting to signal quality

It is important for firms to signal the high quality of their products to consumers in experience goods markets. Conventional wisdom suggests that a high price can be a signal of high quality. However, we argue that the role of price in signaling quality could be weakened when firms resort to the intensive use of targeting in advertising, which could attenuate the informational content of a high price. As a consequence, a high quality firm needs to distort its price more to signal its quality. However, when different levels of targeting are available, a high quality firm may find it optimal to signal its quality with a lower level of targeting.     

Posted price and name-your-own-price in a product line design problem

In this research, we address Name your own price (NYOP) as a mechanism to offer products with transparent, rather than opaque, quality levels. We compare posted price (PP) and NYOP in a product line design problem from a firm’s viewpoint. We first consider the firm offering two vertically differentiated products that each can be priced by NYOP or PP. The quality level of products is considered either as a decision variable or as a fixed predetermined value for the firm. A customer correspondingly decides which product to purchase and if applicable, the bid at NYOP. We characterize both the customer’s and the firm’s decisions under four possible pricing scenarios. The results show that, it is most profitable for the firm to use PP for both products. We then consider if each product is offered by a competitive firm, where quality levels might again be decision variables or fixed. Results show that both competitive firms prefer PP to NYOP when they can create quality differentiation. The firm that offers the product with a lower quality level prefers PP to NYOP for all combinations of fixed quality levels as well. The other firm, with a higher quality level, also usually prefers PP to NYOP; However, it can be better off using NYOP when fixed quality levels are large and close enough to each other. In this case, the preference of NYOP over PP increases as customers’ willingness to pay enhances.     

Price promotions and “freemium” app monetization

The “freemium” model for digital goods involves selling a base version of the product for free, and making premium product features available to users only on payment. The success of the model is predicated on the ability to profitably convert free users to paying ones. Price promotions (or “sales”) are often used in freemium to induce this conversion. However, the causal effect of exposing consumers to such inter-temporal price variation is unclear. While sales can generate beneficial short-run conversion, they may be harmful in the long-run if consumers inter-temporally substitute purchases to periods with low prices, or use them as signals of low product quality. These long-run concerns may be accentuated in freemium apps, where the base version is sold for free, so that sales form extreme price cuts on the overall product combination. We work with the seller of a free-to-play video game to randomize entering cohorts of users into treatment and control conditions in which promotions for in-game purchases are turned on or off. We observe complete user behavior for half a year, including purchases and consumption of in-game goods, which, in contrast to much of the extant literature, enables us to assess possible substitution over time in consumption directly. We find that conversion and revenue improve in the treatment group; and detect no evidence of harmful inter-temporal substitution or negative inferences about quality from exposure to price variation, suggesting that promotions are profitable. We conjecture that the zero price of the base product that makes its consumption virtually costless, combined with the complementarity between the base product and premium features can help explain this. To the extent that this holds across freemium contexts, the positive effects of promotions documented here may hold more generally.

     

Effects of time pressure,type of shopping,and store attributes on consumers’ satisfaction with grocery shopping

The aim of this study is to investigate whether satisfaction with grocery stores is affected by type of grocery shopping in conjunction with time pressure, and which attributes are important for satisfaction. Fictitious grocery stores are constructed according to a fractional factorial design by varying access, price level, supply quality/range, and service quality. In an Internet survey, 1023 Swedish consumers rated satisfaction with major vs. fill-in shopping imagining they were under high or low time pressure. The results showed that satisfaction is higher for fill-in shopping than major shopping, that time pressure has no effect on satisfaction, and that price level, service quality, and product quality/range are more important for satisfaction with major shopping, whereas access is more important for satisfaction with fill-in shopping. It is also found that the importance of attributes for satisfaction depends on type of shopping more than on individual characteristics.     

The Effect of Cross-Channel Price Dis/parity on Ethicality Evaluations and Purchase Intent: The Moderating Role of Price Frame

Using a scenario-based survey with a factorial between-subject experimental design, this study examines the effect of price dis/parity across multiple channels of distribution on customers' ethicality evaluations and purchase intent, with the focus on the moderating role of price frame. Results show that when the varying prices of the disparity policy were all lower than or equal to the uniform price of the parity policy, consumers did not evaluate the disparity policy as significantly less ethical than the parity policy, and were more likely to purchase from the firm with the disparity policy. However, when at least one of the varying prices of the disparity policy was higher than the uniform price of the parity policy, they evaluated the disparity policy as less ethical, and, therefore, were more likely to purchase from the firm with the parity policy, despite price incentives offered by the disparity policy. This finding suggests that the success of a cross-channel price disparity policy depends on the price frame.     

The impact of different price promotions on customer retention

This paper investigates the impact of different price promotion effects regarding two different types of service cost (i.e., a joining fee vs. a monthly fee) on retention intentions for new customers in the long-term service industry. Based on the depreciation curve, mental accounting, and the escalation of commitment theory, we predict that customers’ retention intentions will be higher when they start using a service with a free monthly fee promotion rather than when they start it with a free joining fee promotion. This expectation was confirmed by five studies; experiments, customer survey, and secondary data. The theoretical and managerial implications are also discussed.
