A Multiple-discrete/Continuous Model of Price Promotion

Understanding the effect of temporary price reductions, or price promotions, on sales of consumer packaged goods is an area of ongoing interest, both in academia and in practice. Price promotions, however, are becoming an increasingly important method of managing consumer demand for fresh produce items. Modeling the impact of price promotions must take into account the differentiated nature of fresh produce and the fact that consumers tend to purchase multiple items of only a few of the products available to them. Neither a continuous nor a discrete model of demand is appropriate. In this paper, we apply a multiple-discrete/continuous model of fresh produce demand to study the impact of price promotion on retail apple sales. Our findings show that the brand switching/category incidence effect of promotion is closer to 65/35 than the more usual 80/20 rule (80 percent of the effect is brand switching and 20 percent purchase incidence) when the nature of the decision is appropriately taken into consideration.     

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.

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.     

Retail Market Power in a Shopping Basket Model of Supermarket Competition

Supermarket retailers typically operate with relatively low margins, suggesting a highly competitive retail environment. However, despite the fact that consumers purchase an entire shopping basket at a time from supermarkets, this evidence is largely based on models of retail competition with single-category purchases. In this paper, we develop and test an empirical model of retail price competition that explicitly accounts for the effect of demand complementarity among items in consumer shopping baskets. Relative to the case where consumers purchase products with independent demands, we demonstrate that equilibrium prices are higher for all items when retailers take demand-complementarity into account. Our findings indicate that non-price strategies intended to encourage complementarity, such as co-merchandising, strategic shelf-positioning, or featuring complementary goods tend to soften price competition, and lead to higher equilibrium prices.     

To donate or not to donate? Product characteristics and framing effects of cause‐related marketing on consumer purchase behavior

The present study examines potential influences associated with donation framing, product price, product type, and donation magnitude on cause‐related marketing (CRM) campaigns, where money is donated to a charity each time a consumer makes a pur‐chase. In addition to the main effects of the aforementioned factors, experimental results indicate that beneficial effects of product type (i.e., frivolous products bundled with a cause are more effective than practical ones) occur when donation information is framed in absolute dollar terms. The effects of donation framing are found insignificant when the donation magnitude is high. Influences of donation magnitude on CRM effectiveness are limited in high‐priced items. When the donation magnitude is constant, a donation amount framed in absolute dollar value is more effective than that in percentage terms for low‐priced products, and the opposite is true for high‐priced items. In practice, marketers thus stand to gain not only by matching the donation magnitude in their advertised products with the right price but also by an appropriate “framing” of the offered bundles. © 2008 Wiley Periodicals, Inc.     

The relationship between in-store marketing and observed sales for organic versus fair trade products

To stimulate sales of sustainable products, such as organic and fair trade products, retailers need to know whether their in-store instruments effectively enhance market shares. This study uses sales data and a multilevel modeling approach to explain the market shares of sustainable products according to shelf layout factors, price level, price promotions, and consumer demographics. It argues that the effect of these variables differs between organic versus fair trade products, as buying motives might differ, organic buyers tend to be more loyal, and price is a more informative signal of quality for organic products. Results show that the number of facings has a positive relationship with the market share of fair trade brands, but not with the market share of organic brands. The same holds for the price difference with the leading brand, which is important for fair trade brands but not for organic brands. In contrast, an arrangement of the product category by brand is associated with higher market share for organic brands but not for fair trade brands. Additionally, placement at eye level and clustering of items benefits both types of sustainable brands, whereas they appear to be not very sensitive to price promotions. Finally, higher sales of sustainable products are found in areas where the customer base is older and has a higher education level.     

A comparative analysis of marketing promotions and implications for data analytics

Retailers use many different marketing promotions to increase sales and profits. These promotions include price reductions, coupons, cash mail-in rebates, free gift cards, and buy-one-get-one (BOGO) discounts. The type of promotion used results in different outcomes for demand, profit, average price, consumer surplus, and sales taxes collected. We perform comparative analysis of these five promotions and their outcomes. We show that for the same discount amount, price reductions result in the lowest average price. For products with weakly diminishing consumer utility and low consumer stockpiling, BOGO promotions result in the largest demand, profit, consumer surplus, and taxes collected. Cash mail-in rebates may result in large profit and taxes collected, but they perform poorly in terms of average price paid and consumer surplus. We also find that a retailer offering a delayed incentive (i.e. gift cards and mail-in rebates) offers a larger reward but provides lower consumer surplus than when offering an immediate incentive (i.e. price reduction and BOGO). In a segmented market with a price-insensitive consumer segment, immediate incentives have the disadvantage of allowing price-insensitive consumers arriving during the promotion to obtain the discount, which reduces the discount effectiveness. The addition of more retailer objectives to maximizing profit, such as demand maximization or consumer surplus, increases the effectiveness of immediate incentives. We also provide a framework for estimating the important parameters for evaluating promotion effectiveness using readily available transactional data and examine its accuracy using a simulation experiment.     

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 Impact of Comparative Food Price Information on Consumers and Grocery Retailers: Some Preliminary Findings of a Field Experiment

There is reason to believe that consumers face a difficult task in securing adequate and accurate information upon which to judge relative price levels of competing foodstores. The objective of the research reported here was to investigate the potential of retail food price reporting for correcting this information problem. Both consumer and grocery retailer responses to this comparative food price information were analyzed. A pretest-post-test design with four pairs of experimental-control cities (with replications at two levels of concentration) was employed to collect price data. A modified Solomon-four group design was used for surveys of food consumers in experimental and control cities. The results of analysis of variance models lend support to the hypothesis that price reporting can lower the relative level of food prices, both for items individually identified in a price report and items not identified in the report. The magnitude of this effect varied among the cities. It appears that consumers' role in this experiment was a passive one: consumer behavior and patronage patterns did not change in a manner that would consistently reinforce the competitive effects of the price reports.     

Framing effects in mixed price bundling

In mixed price bundling, the consumer has the choice of buying the individual products separately, as part of a bundle with a discounted price, or not purchasing them at all. Framing effects refer to how the price of the bundle is presented to the consumer. Past studies have focused on perceptual measures and aggregate level results, and have only looked at a subset of different types of price framing in any one study. In this paper we use discrete choice data to investigate whether price framing affects choice in mixed price bundles. We find that the joint, integrated frame results in the highest proportion of respondents choosing the bundle and the fewest choosing “none.” When the prices of items in a bundle are itemized, some consumers are more likely to compare prices separately to their reference prices to evaluate the attractiveness of the deal, but this actually reduces the probability of purchasing the bundle. However, the majority of consumers do not use reference prices and instead follow a simple economic choice model.

The impact of weather on consumer behavior and retail performance: Evidence from a convenience store chain in China

Despite extensive use of weather data to adjust replenishment and inventory strategies in the retail industry, these companies do clearly know the effect of weather on consumer behavior and retail performance. How does weather affect consumers' purchasing behavior and thus retail performance? We study empirically these questions by analyzing more than 6 million transactions made by more than 1.62 million unique consumers at 146 convenience stores in a convenience store chain in China. We choose sun, rain, temperature, and air quality index as the main weather variables. We use the average number of items per order and the average price of each item in each order as indicators of consumer behavior, and use store daily sales as an indicator of retail performance. We found that under rainy weather, people will buy more products with higher item prices in one order. When temperature rises, people will buy fewer products with a lower item price in one order. In addition, sunny weather and rainy weather have a positive impact on daily sales than cloudy weather. Air quality has a negative impact on daily sales, while temperature has a positive impact on sales. Finally, we study the impact of weather on different product categories. We find that the results depend on the product category characteristics.     

WHY ARE GOODS CHEAPER IN RICH EUROPEAN COUNTRIES? BEYOND THE BALASSA–SAMUELSON EFFECT

In wealthy European countries consumer goods tend to be cheaper than consumer services. Usually explained in terms of cost developments and/or foreign‐trade considerations, this trend could also be a reflection of demand‐side regularities. Estimation of a cross‐country demand system indicates that goods are ‘necessities’ whereas services are ‘luxuries’. The relative price of goods responds negatively to the rising supply of goods and positively to the rising supply of services, with the former response being much stronger. If the supplies of both items were to rise at the same speed, the relative price of goods would have to fall.     

Effect of Normative and Affective Aspects on Willingness to Pay for Domestic Food Products—A Multiple Price List Experiment

There is limited knowledge about which factors underlie consumers’ preferences for domestic food products. We used a non-hypothetical multiple-price list experiment to investigate the effect of affective (product-related emotions) and normative (consumer ethnocentrism and subjective norms) factors on consumer willingness to pay for domestic food products. A total of 166 Croatian consumers were given a choice between domestic and foreign food products with different price premiums for domestic food. The results indicate that consumers are willing to pay a premium for both low- and high-involvement domestic food products. Consumer willingness to pay for domestic products is influenced by ethnocentrism, product-related emotions, and sociodemographic variables, but not by social norms.     

Re-incorporating usage situation in choice models: a base for future developments

Abstract

Understanding the consumer’s tendency to adopt new products is an ever-present essential for successful marketing campaigns. This paper presents the findings from two empirical studies that investigate the relationship between consumer innovativeness, price-prestige sensitivity, and need for emotion. A questionnaire survey was used to collect data in both studies from a sample of 668 respondents in two cities in England. The findings show that consumer innovativeness is determined by an individual’s sensitivity to price and their need for emotion. While innovative consumers are sensitive in relating price to prestige, this dispositional relationship varies across products. Furthermore, the findings suggest that enjoyment, which facilitates emotional openness and receptivity, influences innovative consumers to take the emotional route, besides the price-prestige route, to the adoption of new products. These findings have a number of important implications for marketers, particularly for the success of marketing campaigns targeted at innovative consumers who find enjoyment in using new products and are prestigiously sensitive to price.     

Consumer Sovereignty in Healthcare: Fact or Fiction?

We pose the question: Is consumer sovereignty in the healthcare market fact or fiction? Consumer sovereignty in healthcare implies that society benefits at large when healthcare organizations compete to develop high quality healthcare products while reducing the cost of doing business (reflected in low prices), and when consumers choose wisely among healthcare products by purchasing those high quality products at low prices. We develop a theoretical model that encourages systematic empirical research to investigate whether consumer sovereignty in healthcare is fact or fiction. In doing so, we develop a series of theoretical propositions that may demonstrate that consumer sovereignty is more fiction than fact. Specifically, healthcare consumers lack the ability, motivation, and opportunity to choose healthcare products that are high in quality and low in price. Similarly, healthcare firms lack the ability, motivation, and opportunity to compete in ways to develop and market higher quality products at lower prices.

Competent consumers? Consumer competence profiles in Norway

Consumer competence is increasingly important in today’s commercialized society. This paper refers to some main findings from a national representative survey on consumer competences and practices in Norway. To be a competent consumer, it is decisive to be informed about products and to be familiar with how markets function. In this paper, consumers’ self‐reported efforts to keep themselves informed about specific markets is treated as an indicator of consumer competence. First, the results indicate that Norwegian consumers’ competence, according to their own judgement, is rather mediocre. Second, different groups of consumers seem to have different consumer competence profiles. Accordingly, we find that some consumers are price‐conscious in their daily purchases, others are price‐conscious when they make their yearly dispositions in the financial markets, while a third group is community‐oriented and active in the environmentally friendly and ethical product markets. Third, the analysis indicates that consumer competence is an important indicator of how market‐rational and reflective consumers’ choices and practices are.     

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.
