Consumer heterogeneity in the longer-term effects of price promotions

While a significant literature has emerged recently on the longer-term effects of price promotions, as inferred from persistence models, there is very little if any attention paid to whether such longer-term effects vary across different types of consumers. This paper takes a first step in that direction by exploring whether the adjustment, permanent, and total effects of price promotions, and the duration of the adjustment period, differ between consumers segmented based on their usage rates in a product category and their loyalty to a brand. We also investigate whether such consumer segmentation will improve the forecasting performance of persistence models at both product category and brand levels. Expectations are developed based on consumer behavior theory on various effects of price promotions, such as the post-deal trough, the mere purchase effect, the promotion usage effect, and responsiveness to competitor's reactions. Evidence from household-level supermarket scanner data on four product categories is provided. We find substantial differences between consumer segments and provide insights on how managers can increase the longer-term effectiveness of price promotions by targeting each consumer segment with a different promotion program. In addition, consumer segmentation is found to significantly improve the forecasting performance of the persistence model for two of the four product categories. For the other two product categories, consumer segmentation provides forecasting performance similar to that obtained from aggregate-level persistence models.     

基于心理暗示的定价研究

由于信息不对称的存在,消费者无法获知商品的真实价格,在购买前会先对商品进行主观估价,进而形成感知价格的心理变动。价格不确定性和价格感知变化性的交互作用是商品定价对消费者购买决策影响形成心理暗示的现实反映。运用这套作用机制,商家可以通过价格心理暗示方式改变消费者购买决策。本研究通过对文献的归纳和实验研究结果的整理,总结出四种价格暗示方式,并深入分析四种方式作用机制,同时提出价格暗示的应用误区。     

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.     

Auswirkungen der Markttransparenzstelle für Kraftstoffe

The authors analyse how the market transparency unit for fuels in Germany affects both supplier and consumer behaviour. The number of price changes has increased, mainly due to increasing price cuts, as has the spread between the lowest and the highest price of the day — both indicators of intensified competition. The concern that the introduction of the market transparency unit would facilitate collusion appears not to be warranted. In contrast, competition has intensified and consumers are increasingly making use of the price differences. The analysis also reveals that consumers purchased more gasoline in times of low prices (so-called price valleys) in 2015 than they did in 2012. The change in consumer behaviour is an indicator that at least some drivers tend to use fuel price comparison apps fed by data from the market transparency unit.     

Currency Substitution and Price Endings: Right Digit Effect

ABSTRACT

The strategic manipulation of prices. rightmost digits has been a tactic used by retailers in the western world for decades. By studying the internationalization of pricing tactics in a global economy, our research adds a much needed contribution to the literature of price endings and pricing tactics in global markets. We find that at lower price levels, consumers exposed to a 99 ending price in a currency substitution market are more likely to purchase the product compared to consumers in the US market. At higher price levels, on the other hand, consumers in either market situation exhibit no change in purchase intentions. Thus, the 99 ending tactic has no effect on consumers when the product is expensive. The use of the right digit effect by managers in a currency substitution/ dollarized economy as a way of persuading consumers to buy is still likely to be more successful compared to the USA market. As such, firms in a dollarized economy should structure their pricing strategies while taking into consideration the type of product they are offering and the consumer market they are dealing with.     

Friends with benefits: Behavioral and fMRI studies on the effect of friendship reminders on self-control for compulsive and non-compulsive buyers

Does the real or imagined presence of friends invariantly drive consumers to engage in disinhibited behavior, and give in to the “urge to splurge” in the face of consumption temptations? Or might there be situations in which being with friends or even merely thinking of friends or the friendships we have with them can actually improve self-control?In five studies, using a unique combination of controlled experiments examining overt consumer behavior and functional magnetic resonance imaging (fMRI), we propose and show that the extent to which consumers identify a goal conflict between giving in to buying temptations on the one hand and the perceived consequences for maintaining satisfactory relationships with close friends on the other is a critical mediator of whether friendship reminders decrease or increase self-control. We further show that such a goal conflict is most likely for consumers with a chronic, compulsive tendency for uncontrolled, disinhibited acquisition and consumption—for consumers classified as compulsive buyers. For their non-compulsive counterparts, in contrast, acts of acquisition and consumption, even incidental disinhibited ones, are perceived to be less problematic in light of their friendships and hence do not induce a goal conflict to the same extent. Our findings provide insights into social influences on self-control and identify the concept of friendship reminders as a way to reduce a common type of dysfunctional consumer behavior. In addition to enhancing consumer well-being, reducing compulsive buying will substantially reduce handling costs for organizations. Hence, the findings are of academic, societal and managerial relevance.     

Price Intransparency,Consumer Decision Making and European Consumer Law

Price comparison is a basic element of competition. For comparison to work, at least prices need to be transparent. Moreover, price is usually a focal point in consumer thinking and deciding on transactions. Hence, obfuscating prices can be detrimental to consumers. Therefore, it is vital for policymakers to know how transparent pricing is in reality. Commercial practices involving price intransparency can be detrimental to consumer decision making and may be associated with market failure. So, legislative intervention to ensure price transparency is sometimes warranted. Suppliers may disclose and frame pricing information in such ways as to influence consumers. For some suppliers, advantages may be gained by obfuscating price—through practices ranging from the outright hiding of price terms in the small print to subtle ways of throwing in gifts or adding charges during the vending process. Do consumers appreciate the implications of the fact that by framing price in different ways suppliers actually try to influence their demand for products? And how does the law broadly speaking respond to problems of price intransparency? In this article, behavioural science insights are combined with a legal analysis of European consumer law in order to chart some of the detrimental influences of price intransparency on the consumer decision-making process and to answer whether and to what extent European consumer law addresses these issues. In doing so, this article first reviews research from consumer psychology, marketing, and behavioural law, and economics regarding the influence of presentation, framing, and transparency of price on the consumer decision-making process. Subsequently, it describes and evaluates the legal framework offered by European consumer law and how this framework responds to practices of price intransparency. Particular problematic pricing techniques are identified and discussed. In conclusion, attention is drawn to the disadvantages of the increasing full harmonization character of European consumer law for combating price intransparency at Member State level.     

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.     

Getting a feel for price affect: A conceptual framework and empirical investigation of consumers' emotional responses to price information

Behavioral pricing research is cognitively biased. Therefore, the research agenda for this paper is to examine consumers' emotional responses to price information, or price affect. A conceptual framework of price affect based on appraisal theory is proposed. Moreover, a psychometric measure of price affect capturing positive and negative emotions is derived. A field experiment involving N = 1533 consumers reveals that a price increase leads to changes in price affect. Also, negative price affect is related to passive consumer behavior, whereas positive price affect is associated with proactive consumer behavior. Yet, a price increase reduces the importance of price affect in predicting consumer behavior. In addition, both price cognitions and price affect mediate the effect of a price increase on consumer behavior. Consistent with appraisal theory, a price increase exerts its causal influence on price affect through changes in price cognitions. Similarly, price affect mediates the effect of price cognitions on consumer behavior. Finally, price affect improves the prediction of consumer behavior beyond price cognitions. Results suggest that price affect is a stand alone, previously overlooked predictor of consumer behavior. Implications are discussed. © 2008 Wiley Periodicals, Inc.     

人工智能时代个性化定价行为的反垄断规制--从大数据杀熟展开

人工智能时代,数据规模显著扩张,算法能力持续优化。科技实力雄厚、市场力量强大的经营者凭借大数据与算法工具的紧密结合,收集和分析能够反映消费者特征和行为的相关信息,以无限接近消费者购买能力和支付意愿上限的方式对消费者实施个性化定价。个性化定价行为涉及对条件相同的交易相对人在交易价格上实施差别化待遇,可能构成反垄断法所禁止的价格歧视行为。但与以往反垄断实施重点关注的排他性价格歧视不同,个性化定价突出表现为直接针对终端消费者实施的剥削性价格歧视,且在具体情形下呈现出不同的限制竞争效果,引发消费者选择能力与选择范围的双重限制。鉴于此,个性化定价行为的反垄断规制需要准确识别涉案行为,综合判断竞争效果,慎重选择福利标准。对于同时降低消费者剩余和社会总福利的个性化定价行为,可认定其具有限制竞争效果且不具备正当理由,从而构成违法价格歧视;对于降低消费者剩余却提高社会总福利的个性化定价行为,如果选择消费者福利标准则可认定其构成违法价格歧视,如果选择社会总福利标准则可认定其具备正当理由;对于同时提高消费者剩余与社会总福利的个性化定价行为,因涉及消费者之间的剩余转移,对其竞争效果的评价仍待反垄断实施予以明确。     

Helping You to Waste Less? Consumer Acceptance of Food Marketing Offers Targeted to Food-Related Lifestyle Segments of Consumers

ABSTRACT

Consumer households and consumer behavior have been identified as the major cause of food waste in the supply chain. Food marketing might offer products and services that help consumers to reduce their food waste or reduce the consumer-related food waste at the consumer–retailer interface. However, such strategies require consumer acceptance and targeting the right customers. Through an online survey of 800 Danish consumers and a measure of food-related lifestyle, four clusters of consumer segments are identified. The segments are compared with regard to their acceptance of a number of actions consumers can take to reduce food waste or their acceptance of food marketing services they would need to pay for. Acceptance differs with food involvement and the role of the price criterion, as well as with gender, education and age. The findings show how food marketing can help consumers to reduce food waste, through actions targeted to specific segments of consumers characterized by food-related lifestyle differences.     

Dynamische Preissetzung — Wer profitiert?

In the context of digitalisation, recent approaches for automatic price adjustment are gaining importance. However, these approaches can affect consumer behaviour in a way which is disadvantageous for consumers, businesses and the state as a whole. In September 2016, consumer researchers met at the Heinrich Heine University in Düsseldorf in order to discuss the impact of dynamic pricing from the viewpoint of their research fields. As the articles make clear, the researchers found that dynamic pricing based on competitors’ prices is common, while personalised prices are extremely rare. The question arises as to what extent consumers consider dynamic prices unfair. The experts disagree about the necessity of a stricter legal regulatory framework. Furthermore, digital technology can be used to help consumers find their way through the complex online world. Ultimately, the question of who profits–the consumer or the trader–has not been settled. The discussants conclude that there is need for further research in many different research fields.     

Retailer Categorization: How Store-Format Price Image Influences Expected Prices and Consumer Choices

Prior research indicates that consumers may base their retail decisions (e.g., store choice, purchase quantity) on price image, which has been defined as consumer perceptions “of the aggregate price level of a retailer” (Hamilton and Chernev 2013, p. 2). The present research shows that consumers associate different price images not only with specific retailers, but more broadly with various store formats — such as grocery stores, convenience stores, and specialty stores. Six studies provide evidence that store-format price image exerts influence on consumer price expectations and store choice decisions, and that these retailer categorization effects are distinct from the effects of retailer price image.     

Learning About Computers: An Analysis of Information Search and Technology Choice

We estimate a dynamic model of how consumers learn about and choose between different brands of personal computers (PCs). To estimate the model, we use a panel data set that contains the search and purchase behavior of a set of consumers who were in the market for a PC. The data includes the information sources visited each period, search durations, as well as measures of price expectations and stated attitudes toward the alternatives during the search process. Our model extends recent work on estimation of Bayesian learning models of consumer choice behavior in environments characterized by uncertainty by estimating a model of active learning—i.e., a model in which consumers make optimal sequential decisions about how much information to gather prior to making a purchase. Also, following the suggestion of Manski (2003), we use our data on price expectations to model consumers’ price expectation process, and, following the suggestion of McFadden (1989a), we incorporate the stated brand quality information into our likelihood function, rather than modeling only revealed preference data.Our analysis sheds light on how consumer forward-looking price expectations and the process of learning about quality influence the consumer choice process. A key finding is that estimates of dynamic price elasticities of demand exceed estimates that ignore the expectations effect by roughly 50%. This occurs because our estimated expectations formation process implies that consumers expect mean reversion in price changes. This enhances the impact of a temporary price cut. Finally, while our work focuses specifically on the PC market, the modeling approach we develop here may be useful for studying a wide range of high-tech, high-involvement durable goods markets where active learning is important.JEL Classification: C15, C33, C35, C42, C51, C52, D83, D84     

Estimating Consumer Lock-In Effects from Firm-Level Data

This paper proposes a practical method for estimating consumer lock-in effects from firm-level data. The method compares the behavior of already contracted consumers to the behavior of new consumers, the latter serving as a counterfactual to the former. In panel regressions on firms’ incoming and quitting consumers, we look at the differential response to price changes and identify the lock-in effect from the difference between the two. We discuss the potential econometric issues and measurement problems and offer solutions to them. We illustrate our method by analyzing the market for personal loans in Hungary and find strong lock-in effects.     

A cross-country comparison of online deal popularity effect

The paper examines the effect of online deal popularity for service deals in a cross-country context. A 2 (deal popularity: low vs high) X 2 (culture: collectivist vs individualist) quasi experimental design was used to collect data in Australia and Taiwan to examine the consumer reactions toward deal popularity information of service deals on e-retailing websites. Results show consumers' perceived performance and psychological risk mediate the effect of deal popularity on purchase intention both in the Australian and Taiwanese samples. In addition, consumers' reactions towards online popularity information for online service deals do differ across cultures. While high deal popularity increases the Australian consumers' performance and psychological risk perceptions, which in turn lowers their purchase intention, high deal popularity decreases the Taiwanese consumers’ risk perception and enhances their purchase intention. This paper contributes to the broader fields of retailing and services studies by providing insights for online retailers concerning how deal popularity can be leveraged as a means to reduce perceptions of risk for Taiwanese consumers but with caveats for their Australian counterparts. As a first study that examines the effect of online deal popularity for service deals in a cross-country context, it extends the body of knowledge in a fast-changing domain of consumer behavior e-commerce settings.     

An Investigation of Consumer Brand Choice Behavior Across Different Retail Formats

There has been a blurring with respect to the retail formats because of competition and proliferation of different types of formats. In this research, we use a unique scanner panel dataset to investigate how brand choice behavior varies for the same consumer shopping for the same brand across different retail formats. We develop hypotheses pertaining to promotion sensitivity, price sensitivity, package size preference, and effects of demographic and shopping variables on consumer brand choice behavior and test them using a multi-format probit choice model that allows for the estimation of the cross-format differences with respect to the above. We find that consumers exhibit different promotion and price sensitivities in brand choice behavior between the mass merchandise format and supermarkets. Discussions and insights are provided.     

Inflation-induced adaptive behavior

Periods of rapidly rising prices are seen by many as cyclical and pervasive phenomena in modern day economic systems. When rapid price increases occur, they are likely to induce adaptive behavior on the part of consumers. This article reports on a study seeking to analyze consumer inflation-induced adaptive behavior as it relates to three food-related consumer activities–food buying, preparation, and consumption. Results indicate that consumers, in general, attempt to adjust to the changing economic environment in several ways: they exercise more care and planning in food shopping, are more price sensitive and price conscious, are willing to sacrifice convenience but not quality, and try to maintain their usual level of food consumption and food habits. Results also indicate that inflation leads to greater adaptive behavior on the part of lower income consumers.     

Empathic cultural consumers: Pay what you want in the theater

Pay what you want (PWYW) is an increasingly popular sales strategy in which consumers voluntarily decide how much to pay for a product or service. PWYW has often been described as an exercise in the “empathy economy,” where consumers' payment choices might be seen as empowered expressions of their tastes and preferences, and sellers have a stronger incentive for empathizing with them. Beyond their economic interest, PWYW experiences also deserve significant attention in the social sciences given that they challenge several key assumptions of rational choice and neoclassical economic theory, as well as conventional consumer behavior and pricing theories. This paper analyzes three plays performed at the Beckett Theater in Barcelona using PWYW with very profitable outcomes. Our analysis shows that socio-psychological factors, such as payments attributed to others and satisfaction with the play, are the best predictors of customer payments.
