Optimal pricing in social networks considering reference price effect

We study the optimal monopoly pricing strategies in a social network, in which consumers experience a network effect that is dependent on their neighbors' consumptions and a reference price which is the average price received by their neighbors. We establish a two-stage game model for any social network. Utilizing the backward induction, we derive the equilibrium price by maximizing the monopolist's profit. In addition, we apply this model to the two most commonly used network structures: the star network and the bipartite network. We find that both the network effect and the reference price effect play a critical role in deciding pricing strategies in social networks. Moreover, our numerical results demonstrate that whether to implement discriminatory pricing depends critically on the network structure. This work provides monopoly firms a useful guideline for optimal pricing decisions in social network marketing.     

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.     

粮食价格与居民消费价格水平联动效应研究

明晰粮食价格与居民消费价格水平之间的关系意义重大。基于1979—2020年中国粮食价格和居民消费价格水平年度数据,运用向量误差修正模型和Granger因果分析,对粮食价格与居民消费价格水平间的关系进行实证分析。结果表明:短期内,居民消费价格水平对粮食价格的影响远大于粮食价格对居民消费价格水平的影响,居民消费价格水平变动与粮食价格变动之间存在单向Granger因果关系;长期看,两者之间存在双向Granger因果关系。根据研究结论,提出了加强粮食价格和居民消费价格监测、稳定粮食价格水平、加大市场调控等对策建议。     

A meta-analysis of the impact of price presentation on perceived savings

Pricing is one of the most crucial determinants of sales. Besides the actual price, how the price offering is presented to consumers also affects consumer evaluation of the product offering. Many studies focus on “price framing,” i.e., how the offer is communicated to the consumer —is the offered price given along with a reference price, is the reference price plausible, is a price deal communicated in dollar or percentage terms. Other studies focus on “situational effects,” e.g., is the evaluation for a national brand or a private brand, is it within a discount store or a specialty store. In this article, a meta-analysis of 20 published articles in marketing examines the effects of price frames and situations on perceived savings. The results reveal many features that significantly influence perceived savings. For instance, while both the percent of deal and the amount of deal positively influence perceived deal savings, deal percent has more impact. Further, the presence of a regular price as an external reference price enhances the offer value of large plausible deal and implausible deals, but not of small plausible deals. Thus, high value deals should announce the regular price, but not low value deals. Overall, the results have several useful insights for designing promotions.     

Exploring the effect of retail sector and firm characteristics on retail price promotion strategy

This study examines why retail price promotion strategies vary across retail sectors and across firms within sectors. Using hierarchical linear modeling and a sample of 38 firms from 11 retail sectors, the authors investigate how two sector-level characteristics, related to product assortment perishability and heterogeneity, and three firm-level characteristics, related to retailer differentiation, number of stores, and average store size, influence price promotion decisions. The results indicate that assortment heterogeneity moderates the positive influence of perishability on price promotion activity; scale and scope also have significant effects. These results offer fresh insight into the ongoing debate surrounding stable versus promotional pricing, suggesting that the benefits of a particular strategy are driven largely by a complex interaction between sector-level characteristics as well as firm-level cost advantages.     

The market value for product attribute improvements under price personalization

Personalization of the marketing mix is a topic of much interest to marketing academics and practitioners. Using discrete choice demand theory, we investigate the aggregate market value for product attribute improvements when firms are engaged in personalized pricing. Our results provide a theoretically grounded rule for how to aggregate consumer valuations to assess the overall profitability of attribute improvements under price personalization. Under common pricing, each consumer contributes the same margin. Profitability of an attribute improvement is thus driven by inducing more consumers to buy. Consumers with high choice probabilities are given less weight in the market valuation under common pricing as they are less responsive to attribute improvements. Under personalized pricing, profitability of an attribute improvement is driven by extraction of consumer surplus from high valuation consumers. Consumers with higher valuations, and consequently higher choice probabilities, are given more weight in the market valuation under personalized pricing. Since individual consumers play a more central role in the market valuation under personalized pricing, estimation of consumer-level valuations is of increased importance. Under common pricing, the market valuation for an attribute improvement is robust to extreme estimates of the consumer-level valuations. Through our theoretical and empirical analyses, we demonstrate that this robustness does not hold under personalized pricing.     

Product category determinants of price knowledge for durable consumer goods

Existing research in pricing has not extensively examined the impact of the product category on consumers’ knowledge of prices, especially for durable goods. In two empirical studies, this paper examines the influence of the product category on consumers’ knowledge of prices for durables. The first study utilizes data from the popular television game show The Price is Right to establish significant cross-category variations in price knowledge, while the second study links these variations to the specific characteristics of each product category. The results extend existing research findings by isolating the impact of product category determinants, such as purchase frequency, advertising exposure, and use of the price-quality cue, on consumers’ knowledge of prices.     

Spending propensity and price perceptions

ABSTRACT

This article presents a systematic investigation of how Spending Propensity moderates consumers’ perceptions of prices. Results from three studies are presented. Studies 1 and 2 reveal that, in the absence of any external cues, consumers who are predisposed to spending freely evaluate a posted price more favorably than those who are not. Such consumers also report anticipating less pain associated with spending than those who are not inclined to spend. Additionally, Study 2 informs that simple price communication tactics, without any real reduction in price, may be effective at mitigating the pain felt among those who are less inclined to spend. Furthermore, such tactics are capable of reducing, and even reversing, the gap between those who are not predisposed to spending and those who are. Finally, Study 3 explores how spending propensity moderates consumers’ perceptions of a discount.     

Semantic cues in reference price advertisements: The moderating role of cue concreteness

Retailers use a variety of semantic cues to advertise discounts at their stores. In this paper we introduce the concept of cue concreteness and examine its impact on effectiveness of semantic cues. Four studies were conducted which concur with the findings of earlier research in this area and expand our knowledge about the effectiveness of semantic cues. Results indicate that between-store cues are perceived to be more effective than within-store cues at moderate price discount levels only when the cues are concrete in nature. In addition, a between-store cue resulted in more favorable evaluations than a within-store cue when the ad was viewed at home, but only when the cue was concrete. Implications for marketers and public policy makers are discussed.     

Feed them facts: Value perceptions and consumer use of sustainability-related product information

More than ever, consumers are demanding sustainable options on retail shelves. Retailers, however, are not finding clear evidence of the financial benefits for doing so. This study attempts to provide concrete suggestions to retailers on what kinds of sustainability-related information to provide to consumers. Our online study of approximately 3600 participants provides evidence that, when provided with full information on all sustainability-related attributes, consumers make price/benefit trade-offs resulting in the selection of higher priced, more value-differentiated products. Further, when sustainability-related information is provided for some products and not for others, consumers will “punish” the non-sustainable option. Managerial implications are discussed.     

Retailers' control of reference price given product category and level of competition

This paper examines the conditions that make reference price manipulation beneficial to retailers. The paper offers a modelling approach that is based on two distinct dimensions: product category, and degree of market competition. The model shows that reference price manipulation in a competitive market is less beneficial to retailers than it is in a monopolistic market. Reference price manipulation of a specific product is most advantageous to retailers when it is a frequently purchased, low-priced product in a monopolistic market. For an infrequently purchased, high-priced product in a competitive market, reference price manipulation is less beneficial. The analysis gives rise to policy implications that could potentially improve consumer welfare.     

The price is right? Guidelines for pricing to enhance profitability

Pricing is a key element of the marketing strategy. It does not require significant investments or resources, and is perhaps the most accessible lever to manage profitability. Even minor fluctuations in pricing can have a significant impact on both revenues and profitability. As such, lack of careful planning in pricing is a wasted opportunity. With this as a backdrop, we make a case for precision in pricing to enhance profitability. Since consumers vary in their preferences, motivations, and propensity to spend, they assign varying degrees of emphasis regarding price upon their purchase decisions. We argue that pricing is a creative exercise in math and behavioral economics, and companies should stay focused on profits. We also provide a series of guidelines for creating effective base prices, and then modifying them to enhance profitability. Finally, monitoring prices at the transaction level will reduce leakage in profits and further add to the bottom line.     

Effects of price reframing tactics on consumer perceptions

This article compares the effects of three pricing tactics—temporal reframing of prices (TRP), measure-based unit pricing (UP), and usage-based UP—on various consumer perceptions. Although these tactics are similar as they all reframe retail prices to a smaller amount, dissimilarity also exists as the respective units used for calculating these reframed prices differ. A laboratory experiment was performed to draw comparisons among the three types in a context of print advertisement. The results suggest that usage-based UP provided the most beneficial information for consumers; however, the differences between usage-based UP and TRP were not substantial.     

Profiling the flyer-prone consumer

The purpose of this paper is to predict the differences between highly prone and less prone consumers to store flyers in terms of their sensitivity to economic, shopping-related and demographic variables. The empirical findings show that the flyer-prone consumer׳s profile somehow differs from the characteristics of consumers more prone to other types of promotion and to deals in general. The managerial implications underline that including a price-discount support is not essential if manufacturers and retailers wish to increase the probability of store flyers being consulted by a consumer. Nevertheless, the credibility of flyers depends on consumers’ perception of potential savings being maintained.     

The impact of advertising on consumer price sensitivity in experience goods markets

In this paper we use Nielsen scanner panel data on four categories of consumer goods to examine how TV advertising and other marketing activities affect the demand curve facing a brand. Advertising can affect consumer demand in many different ways. Becker and Murphy (Quarterly Journal of Economics 108:941–964, 1993) have argued that the “presumptive case” should be that advertising works by raising marginal consumers’ willingness to pay for a brand. This has the effect of flattening the demand curve, thus increasing the equilibrium price elasticity of demand and the lowering the equilibrium price. Thus, “advertising is profitable not because it lowers the elasticity of demand for the advertised good, but because it raises the level of demand.” Our empirical results support this conjecture on how advertising shifts the demand curve for 17 of the 18 brands we examine. There have been many prior studies of how advertising affects two equilibrium quantities: the price elasticity of demand and/or the price level. Our work is differentiated from previous work primarily by our focus on how advertising shifts demand curves as a whole. As Becker and Murphy pointed out, a focus on equilibrium prices or elasticities alone can be quite misleading. Indeed, in many instances, the observation that advertising causes prices to fall and/or demand elasticities to increase, has misled authors into concluding that consumer “price sensitivity” must have increased, meaning the number of consumers’ willing to pay any particular price for a brand was reduced—perhaps because advertising makes consumers more aware of substitutes. But, in fact, a decrease in the equilibrium price is perfectly consistent with a scenario where advertising actually raises each individual consumer’s willingness to pay for a brand. Thus, we argue that to understand how advertising affects consumer price sensitivity one needs to estimate how it shifts the whole distribution of willingness to pay in the population. This means estimating how it shifts the shape of the demand curve as a whole, which in turn means estimating a complete demand system for all brands in a category—as we do here. We estimate demand systems for toothpaste, toothbrushes, detergent and ketchup. Across these categories, we find one important exception to conjecture that advertising should primarily increase the willingness to pay of marginal consumers. The exception is the case of Heinz ketchup. Heinz advertising has a greater positive effect on the WTP of infra-marginal consumers. This is not surprising, because Heinz advertising focuses on differentiating the brand on the “thickness” dimension. This is a horizontal dimension that may be highly valued by some consumers and not others. The consumers who most value this dimension have the highest WTP for Heinz, and, by focusing on this dimension; Heinz advertising raises the WTP of these infra-marginal consumers further. In such a case, advertising is profitable because it reduces the market share loss that the brand would suffer from any given price increase. In contrast, in the other categories we examine, advertising tends to focus more on vertical attributes.

The role of attributions in consumer perceptions of retail advertisements promoting price discounts

This study examines whether information in an advertisement promoting a price discount is capable of affecting attributions made about the price reduction and whether these attributions, in turn, affect consumer perceptions and evaluations of the sale. Findings show that price image of the retail advertiser had a strong effect on attributions pertaining to the merchant and a marginal effect on product attributions. The attribution variables, in turn, explained significant amounts of variance in criterion variables measuring consumer perceptions of value, attitude toward the ad, and shopping intentions, beyond the variance explained by the store and discount claim variables manipulated in the study. These results suggest the importance of the role of attributions made by consumers when exposed to ads promoting discounts.     

The effects of competitive context on consumer response to price changes

ABSTRACT

This paper aims to understand how a brand’s price level, relative to its competitors, will affect consumers’ responses to price changes of the brand. The study uses experiments to examine brand choice responses to price increases and decreases across contexts differing in competitor brands and their respective prices. These experiments are conducted with six consumer goods categories. The research identifies three key factors that affect the size of responses to brand price changes – (1) passing a competitor brand’s price, (2) narrowing versus widening the price gaps with competitors, and (3) whether competitors are predominantly higher or lower priced brands.     

Maximizing earnings and price fairness perceptions in online consumer-to-consumer auctions

We examine the effects of starting bids on seller earnings in online consumer-to-consumer auctions. As starting bids increase, and the number of bidders increase, seller earnings increase. Both the affiliated private value model and a reference price explanation explain seller earnings. Bidder price fairness perceptions are also evaluated and, higher starting bids positively impact price fairness perceptions for winning bidders but have an adverse effect on losing bidders. In total, these findings suggest that sellers receive greater earnings as well as no adverse price fairness perceptions from winning bidders by setting starting bids higher.
