A Conjoint Analysis of Quality Wine

Abstract

Weighted least squares approach for conjoint analysis is used to examine buyer preferences towards wines produced in different Spanish regions. Two producer regions are considered, Na-varra and Aragon, and three wine attributes: price, origin and grape vintage year (wine age). In both regions, differences between urban and rural consumers' preferences are tested. Results indicate that the origin of the grapes is the most important attribute for the wine consumer. Rural consumers prefer locally produced wines while Rioja wines are better considered by urban consumers. The price and the age of the wines are secondary attributes in consumer preferences. Finally, some market segments are formed based on individual consumer preferences and some of their sociodemographic characteristics in order to address differentiated marketing strategies to these segments.     

Explanatory factors for efficiency in the use of social networking sites—The case of organic food products

In some markets, organic foods face problems such as consumer misinformation and confusion, high prices compared to conventional equivalents, or few points of sale. The answers to these problems include information and communication technologies, particularly social networking sites (SNS), given their potential for conveying information and connecting customers and suppliers at less cost. It would be useful to ascertain the psychology of social media use and which factors determine SNS efficiency among organic producers. This study of the efficiency of SNS use in two strategic sectors for Spain—olive oil and wine—used data envelopment analysis and, in a second stage, qualitative comparative analysis (QCA) to detect the contextual variables that explain the highest efficiency indices. The results showed that the more market‐oriented sector (wine) has a higher average efficiency of SNS use and pointed to the following explanatory factors: SNSs mentioned on corporate websites, number of employees, the manager's educational background, and length of SNS use.     

Consumer attitudes and loyalty towards private brands

Private or store brands improve the efficiency of consumer decision making by offering equivalent quality products at lower prices. The present study evaluated consumer attitudes towards private brands with the goal of understanding their appeal in order to enhance efforts to convince more consumers to buy them. We used three samples (ns = 279, 245 and 305) of US consumers to compare attitudes of buyers of private and national brands in three product categories: orange juice, cereal and bottled water. The results show that private label buyers (23% of orange juice, 6.5% of cereal and 14% of bottled water buyers) consider brands themselves to be less important and private brands to offer better performance than do national brand buyers. When asked about specific brands, national brand buyers tended to be price insensitive towards national brands, and private label buyers price insensitive towards store brands. In addition, the national brand buyers saw some of the national brands to be more relevant to their lifestyles and needs, but the private label buyers saw the private labels the same way. Being relevant to consumers' lives appears to influence brand selection. Besides touting lower prices, private brand promotions might stress the equivalent performance of private labels and create promotions showing how these brands can be relevant to consumers' lifestyles and needs.     

Value-based pricing in competitive situations with the help of multi-product price response maps

This article introduces multi-product price response maps for various value pricing applications in competitive situations. The maps are based on the direct elicitation of individual willingness to pay (WTP) as a range for competing products; they reveal an individual's or market's choice probability for a focal product, at its own and competing products' prices. Transforming the price response into profit, revenue, or unit sold maps supports optimal pricing decisions. The maps are also useful for optimizing profit differences from the closest competitor and for portfolio pricing. Managers can use a consumer indecisiveness map, gained from the WTP range data, to devise complementary marketing measures at prices where consumer uncertainty is high. The illustration of this approach uses two empirical examples, featuring two or more competing consumer goods, and demonstrates the predictive and external validity of these proposed maps.     

Commodity Prices at Record Level

Crude oil quotations have reached a historical high and prices for industrial raw materials continue to rise. However, the feared negative effects of higher commodity prices on economic growth appear to be limited in the consumer countries and producers would like to maintain the higher price level. Will they succeed?     

Evaluation of Alternative Market Channels for Farm-Raised Catfish

Abstract

Catfish producers have traditionally marketed catfish to centralized processing plants that eviscerate and fillet the fish for distribution to the food service sector and to retail markets. However, low prices offered by the processing plants since December of 2001 have fallen short of the breakeven costs for some farmers. Developing alternative marketing channels that offer higher prices to catfish producers have been suggested to help improve farmers' revenue by spreading price risks. The objective of this study was to examine the effect of alternative marketing channels and average size on the average price of farm-raised catfish. The results of this analysis suggest that catfish farmers can increase the average price received for live food-sized catfish by decreasing the percentage of fish marketed to processing plants and live haulers, while increasing the percentage of fish marketed to retail outlets in an average size range of 0.57 kg to 0.90 kg. This can be achieved with on-farm value-added processing. However, retail outlets are relatively limited and may not provide a solution to large-scale producers of the catfish farming industry.     

Price Knowledge During Grocery Shopping: What We Learn and What We Forget

Past research on consumer price knowledge has varied considerably partly due to differences in how and when price knowledge is measured. This paper applies a multi-point, multi-measure approach to reconcile differences in past price knowledge research by examining systematic relationships between time of measurement and type of measures applied. Examination of consumer price knowledge before, during, and after store visit sheds light on what is measured at the individual points in time: episodic price knowledge and/or reference prices? With a between-subjects design interviewing 1,204 respondents, the authors investigate three price knowledge measures (price recall, price recognition, and deal spotting) demonstrating that these are hierarchically related. Results suggest that reference prices dominate before store visit, but also that episodic price knowledge, surprisingly, is still accessible at the store exit. These findings enable the authors to reconcile diverging results from past research, showing how consumer price knowledge evolves and suggesting that the vast majority of consumers learn about prices, whether consciously or unconsciously, during grocery shopping. Thus, when applying a multi-point, multi-measure approach, consumers appear to know more about prices than suggested by past research. Determinants of price knowledge are also examined and the results indicate that price knowledge builds up not only because of active search but also due to accidental exposure to prices and with low degrees of conscious processing. Implications for managers are discussed.     

The multichannel pricing dilemma: Do consumers accept higher offline than online prices?

Whether to unify or discriminate prices in offline and online channels is a controversial topic that can be central to whether offline retailers survive in the marketplace. Field data evidence from a large multichannel retailer reveals a sobering picture. On average, only offline price premiums of approximately 2% seem feasible, and such premiums vary largely by product categories and price levels. High-priced products, which consumers perceive as risky, tend to allow offline price premiums, as do low-priced, takeaway items. However, in between these two extremes, the results show no potential for offline price premiums. Drawing on price fairness theory, we further explore consumer responses to higher offline prices in three experimental studies. In contrast with the assumptions of price fairness theory, the provision of purchase advisory services and communication of the price motive hardly stimulate consumer acceptance of higher offline prices in our context. However, the findings reveal important heterogeneity in consumer responses depending on their market segment, because some market segments indeed respond less negatively to higher offline prices. In addition, consumers accept offline price premiums for unplanned purchases.     

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。     

Consumers' SKU choices in an online supermarket: a latent class approach

Abstract

This study examines the effects of loyalty and e-marketing mix variables on the choices of online consumers at the stock-keeping-unit (SKU) level. Using a panel dataset from an online supermarket, we estimate a discrete choice model of a frequently purchased product; generate the refined smoothing constants of the loyalty variables for brand, size, and SKU; and adopt the latent class approach to address consumer heterogeneity. The findings suggest that SKU loyalty is a better predictor of consumer choices than brand and size loyalty. Although online consumers are not sensitive to the net prices of SKU alternatives, they are attracted to price promotions. While webpage display has little effect on SKU choices, speedy delivery has a positive impact. The latent class approach significantly improves model fitness and classification accuracy. Analysing consumer choices at the SKU level can help online supermarkets with promotion planning and inventory and distribution management to improve customer satisfaction and profitability.     

Retail channel price discrimination

This paper examines price differentials of identical items across retail channels. Many consumer packaged goods are sold through both grocery and drug stores. Liquor is unique in that in much of the country there is a third retail channel of distribution, liquor stores. If consumers in each retail channel differ in their willingness to pay for certain items, then sellers can exploit those differences and charge different prices for the same items in each channel. We examine a unique data set of pooled cross sectional retail scanner data on wine to test whether sellers use retail channel to identify heterogeneous consumer market segments and engage in price discrimination. We begin by presenting a model of price discrimination by retail channel along with behavioural assumptions regarding shoppers in each channel. Next we examine sales by retail channel and find persistent price differentials for the same item across retail channel after controlling for sample selection bias and seasonality. Lastly, we estimate the price elasticity of demand correcting for endogeneity and find differences across channel consistent with the price differentials. The extent of price differential, however, differs significantly with respect to price point.     

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.     

Price Awareness and Consumers’ Use of Deals in Brand Choice

There is evidence that consumer knowledge of prices is limited, implying that, on occasions, consumers may not be fully informed of prices when making a brand purchase. On such occasions, how do consumers make their brand choice decision? One possibility is that consumers use their expectation of prices. This raises an interesting question. To what extent is brand purchase either a function of preferences and posted prices or, of preferences and expectation of brand prices? Another important issue relates to the role of displays and features in simplifying consumer brand choice. First, do promotions cause consumers to restrict their attention to only promoted brands? Second, do promotions affect the price aware consumers more than the price unaware consumers? Our study uses scanner data on ketchup and peanut butter categories to answer the foregoing questions. We find that between 40 and 50% of the purchases are made by consumers using expectations of prices rather than posted prices. Consumers using price expectations may be thought of as being “unaware” of prices. We also find that promotions cause some consumers to focus exclusively on promoted brands, and this effect is greater on the price aware consumers than on the price unaware consumers. Our findings have an important bearing on the rationality of consumer expectation of prices, especially of the promoted brands. Price aware consumers act as a check against firms promoting without accompanying price cuts.     

Setting prices in mixed logit model designs

We investigate different procedures to set prices in designs for choice-based conjoint analysis using the mixed logit model which captures latent consumer heterogeneity. Besides discrete attributes, we include a linear price term in the deterministic utility function thereby treating price as continuous variable. We consider two different price intervals and several price sets which contain either two or three prices. We compare these alternatives to set prices by simulating choices for different constellations on the basis of the mixed logit model. Furthermore, we generate ten designs simultaneously instead of just one. Using these simulated choices, we estimate the parameters of the mixed logit model in the next step. To reduce the needed sample size and computation time caused by accounting for latent consumer heterogeneity, we apply Halton draws and set a minimum potential design for prior draws. ANOVA with root mean squared error between estimated and true price coefficient values of individual consumers as dependent variable shows that using more extreme prices as interval bounds and one intermediate price positioned to the right of the interval performs best.     

Ansatzpunkte und probleme einer erfolgsbeurteilung beim neutralen gütertest

Independent test reports represent an important element in the sphere of consumer information. Evaluation of the impact of previous information and the search for better policies in future would certainly be useful. What is needed at this point is a scientific analysis oftest-report efficiency. Data concerning the dissemination and use of test reports exist but do not provide sufficient information to describe the further and more substantial benefits of testing institutions. It is the purpose of this paper to set out an approach to such an analysis of test efficiency by suggesting a set of evaluative criteria and a conceptualisation of some of the major problems involved in the empirical analysis of test efficiency. First of all, the actual and potential goals of testing institutions are formulated, since it is out of this set of goals that one can draw a list of appropriate test efficiency criteria. Such criteria include: (a) the consumer's knowledge of relevant products, prices, and services; (b) improvement of the consumer's purchasing decisions in terms of his own needs and scarce resources as well as of environmental protection; (c) improvement and stabilisation of regulative mechanisms, particularly the consumer's influence on the marketing system. Secondly, the various areas of test-report effects are analysed. In this context most authors concentrate solely upon the consumer and his purchasing behavior. The question presents itself, however, whether test effects upon the marketing system can be neglected. Considering the direct and the indirect impact of test reports on product marketing (both for merchants and for producers) and on the “consumer interest,” the answer is clearly in the negative. If test reports lead to changes, for example, in product quality and price, benefits to consumers can be said to exist even if consumers themselves do not use test reports in their actual purchasing decisions (“non-use benefits"). Such impact of test reports can be of great value especially to the poor. The body of this paper then deals with various efficiency indicators both in the consumer and in the marketing system. The indicators presented in the consumer section include: (i) perception of needs; (2) perception of relevant products (quality, price, etc.); (3) simplification in the purchase decision; (4) articulation of needs; (5) results in the context of bargaining over price and service; (6) product quality and satisfaction with the product and service; (7) post-decisional articulation of dissatisfaction and complaining behaviour; (8) external effects of consumption on scarce resources and environment. Efficiency indicators concerningmarketing effects are those of the following factors: (1) products; (2) prices; (3) channelling and distribution; (4) communication and information. In addition, such structural variables as competition effects and quality consciousness are treated. Where available, empirical data related to these various effects of test reports are also reported. The final section of this paper deals with the question of whether and to what extent certain effects can be seen as a result of consumer test reports. The problem of causality endemic to such analyses of efficiency in complex social systems cannot be resolved, of course, as it can in controlled experimental situations. Some other approaches to the establishment of causal indicators are therefore considered. Generally speaking, the chief concern of this paper lies in the development of a social-scientific basis for future consumer information policies, although a substantial part of the approach presented here can clearly be of value in many other areas of consumer policy. Er möchte Herrn Prof. Dr. Hans Raffée für wertvolle Anregungen herzlich danken.     

Modelling the asymmetric responses of price level to oil price changes in Qatar

This paper inspects the asymmetric effect of oil price on prices level in Qatar. To achieve that, we proceed by employing a nonlinear autoregressive distributed lag (ARDL) approach on data during the period 1990Q1–2014Q4. The estimation results show evidences of an incomplete and asymmetric influence of oil price on price level in the long term. Moreover, we find that price responses to negative changes in oil price is greater than its response to positive changes. Given Qatar’s economic features, a decrease in oil price could cause lower imports and production prices and consequently a substantial influence on domestic prices level. However, the lower effect of positive oil price changes on consumer prices can be explained by the subsidies system, the consumption patterns, and the exchange rate regime.     

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.     

What drives competitive webrooming? The roles of channel and retailer aspects

ABSTRACT

Competitive webrooming, the phenomenon in which consumers gather product information online but ultimately purchase the product in an offline store of a competing retailer, has gained traction and become a major threat for retailers. To gain a deeper understanding of its drivers, we surveyed 1081 retail customers about their most recent consumer electronic product purchase to examine the impact of channel-related aspects as well as retailer-related aspects – a dual approach that has not been applied previously. A channel’s anticipated after-sales service and price level are the strongest predictors for webrooming. Moreover, retailer aspects determine whether customers simultaneously switch retailer when webrooming. A retailer’s assurance of delivery, including payment modalities, return policies, and product obtainment, as well as competitive product prices motivate consumers to switch retailer when webrooming. These results suggest that customers have a fundamental need for certainty within and after the buying process, which can be satisfied by both channel and retailer. Additionally, this is the first study to empirically test for interactions between channel and retailer aspects, as they are likely to occur in real shopping situations. We identified two interactions: First, a retailer’s assurance of delivery can compensate for an anticipated lack of a channel’s after-sales service, dampening the impact of the latter on competitive webrooming. Second, retailer’s price attractiveness acts in a similar vein. Hence, to steer customers into channels and/or keep them with the company, retailers should emphasize their price attractiveness as well as assurance of delivery.
