The different faces of coupon elasticity

Coupons account for over two-thirds of all consumer promotional efforts initiated by the manufacturers of consumer goods. In this study, the impact of coupons on brand sales is investigated and how that impact decays over the life of the coupon is demonstrated. Specifically, we present an econometric model that can capture coupon effects in terms of equivalent price reduction, account for coupon effects over time, allow inference of coupon effects when retailers decide to double or triple the coupon value, and provide both self-coupon and cross-coupon elasticities at different levels of aggregation. A widely used sales response model is adapted, and an analytical model is proposed to estimate both the self-coupon and cross-coupon (face value) elasticities of sales at the store level. From the store-level elasticity estimates for a given week, the authors analytically derive the coupon elasticities for the chain level by aggregating across stores, and over the life of the coupon by aggregating over time. The proposed sales response model is estimated with the data obtained from three markets for various product categories, and the coupon elasticities are computed. The proposed framework allows one to demonstrate the hypothetical equivalence of a shelf-price reduction for a given coupon face value in each week. Also, the effect of doubling the face value of a coupon results in more than a proportionate increase in elasticity. The authors find that both self and cross-coupon elasticities are much smaller in magnitude than the average self and cross-price elasticity measures reported in the literature.     

Omnichannel retailing operations with coupon promotions

This paper explores an omnichannel retail system under which the retailer offers coupons via online channels for market share and profit. It investigates the action mechanism of coupon promotion on omnichannel price and operational decisions by employing a theoretical model. Three coupon distribution modes are investigated; a scenario in which the omnichannel retailer does not offer coupons, offers coupons with a common face value, or offers coupons with a different face value. The results show that the distribution of coupons does not always lead to increased market share. Rather, market volume may be reduced if the competition between different channels is intense. When conducting a coupon promotion, the retailer always charges a higher price, but if the negative effects of coupon promotion for the competitive channel are relatively large, the retailer will reduce their price. Larger cross-selling revenue comes from ‘Buy Online, Pick Up in Store’ channel, indicating a stronger willingness to offer coupons and higher profits for the retailer. If the retailer takes the channel characteristics and consumers' channel preferences into consideration and offers different coupon face values across channels, they will derive higher profits.     

Coupons in context: discounting prices or decreasing profits?

A coupon is a commonly used sales promotion device offering the user a discount on the purchase of a product. Consumer coupon offerings are also becoming increasingly diverse: from “% off” and “$ off” to “Buy one, Get one free” (BOGO) offers and co-promotions (Buy X, Deal on Y). This paper reports the results of three experiments that examine whether the economic value of a coupon is a source of information to infer the price of the product/service, and the quality of the product/service, which inference can undercut the economic value, with resulting consequences for deal evaluations and purchase intentions. The framework predicts, and empirical results show, that increasing the value of the coupon does not always improve deal evaluations or purchase intentions. This could imply lower profits for the company. The presence of past price information about the brand, information about prices of other brands offered by the company, and information about competitors’ prices moderate the impact of coupon value on brand-related inferences. When such alternate sources of information are present and are diagnostic of the price of the promoted product, consumers are less likely to infer price and quality from the value of the coupon and higher coupon values are more likely to increase deal evaluations and purchase intentions. Implications for managers designing and communicating promotions are offered.     

Price,online coupon,and store service effort decisions under different omnichannel retailing models

This paper explores three omnichannel retailing models—that is, a Buy-Online, Pick-Up In-Store (BOPS) model, a Showroom model, and an Interactive model (a model that combines the characteristics of BOPS and Showroom)—under which the retailer offers coupons online and invests in service efforts offline. For each omnichannel retailing model, three coupon distribution scenarios (i.e. no coupon, coupon with a common value, and coupon with a different value) are discussed to investigate coupon promotion policies and omnichannel operation strategies. Profits in the omnichannel system and under each model are compared by deriving three decision values: price, coupon value, and service effort. The key findings show that the retailer achieves profit improvement when the incremental purchasing reaches a large value. In addition, a great service effort coefficient leads to a high price, service effort, and retailer profit. The service effort and coupon value in the Showroom model are the largest among the three omnichannel models, while its profit is the lowest. Conversely, although the retailer invests less in service effort, and the price and coupon value are not too large in the BOPS model, the retailer still gains the highest profit. Additionally, in the BOPS model, it is profitable for the retailer to distinguish the coupon value for the online-only and BOPS channels when consumers are less sensitive to the online-only channel’s coupon. However, in the Interactive model, the retailer derives increasing profit by providing coupons with a common value for the online-only and BOPS channels.     

Does shelf space management intervention have an effect on calorie turnover at supermarkets?

Despite recognizing the potential of retail settings for interventions aimed at bringing the rate of obesity down, there have been few attempts to implement experimental studies aiming to increase consumption of healthy foods and decrease consumption of unhealthy foods in the retail setting. An experimental controlled trial has been conducted using 10 supermarkets in Denmark. The study looked specifically into the possible effect of shelf space management intervention at supermarkets. The study found a significant intervention effect for individual products targeted by the project. But overall, care is needed to interpret results on aggregate level since statistical findings do not support category wide effect of shelf space intervention.     

Category-specific coupon proneness: The impact of individual characteristics and category-specific variables

In seeking to enhance the effectiveness of coupon promotions, researchers have long sought to identify “coupon prone” consumers. Previous measures of coupon proneness have not examined differences in coupon usage across product categories and have ignored the confounding effect of coupon attractiveness. An Item Response Theory (IRT)-based framework overcomes these limitations and yields category-specific estimates of propensity to redeem coupons that are independent of coupon attractiveness. The authors utilize an IRT-based model to estimate consumers’ category-specific propensities to redeem coupons for two product and two service categories, and investigate how coupon proneness varies across consumers and across categories as a function of individual characteristics and category-specific variables.The authors find that category-specific measures of propensity to redeem coupons achieve an average accuracy of 89 percent in predicting redemption intentions. Propensity to redeem coupons is also found to be related to category-specific brand loyalty and perceived coupon availability, as well as to individual characteristics such as general coupon proneness, value consciousness and price consciousness. These findings highlight the importance of studying coupon proneness at the category level and suggest that the IRT-based approach has considerable promise as a methodology for studying coupon usage. Using the approach proposed in this study, marketers can forecast the impact coupons are likely to have in their particular category, rather than relying on general coupon proneness measures to predict coupon redemption rates at the category level. The study's findings can also be used to identify categories and consumer segments where coupon promotions are likely to have a larger impact, and have important implications for managers planning joint couponing strategies.     

A comparison of produce prices in Costa Rica: farmers' markets,produce markets and supermarkets

Following a review of the history and organization of farmers' markets in Costa Rica, a comparison was made of prices offered to consumers at farmers' markets, produce markets and supermarkets in Costa Rica. Findings reveal there are substantial price savings to Costa Rican consumers that shop at local farmers' markets for fruit and vegetables compared to produce markets and supermarkets.     

Digital coupon promotion and platform selection in the presence of delivery effort

In recent years, physical retailers have started selling products to consumers through either third-party or self-operated online platforms. Doing so, they face demand which depends on digital coupon promotions, delivery effort by the platform (i.e., deliver products from retailers to consumers), and channel preference. In this paper, we develop a game-theoretic model to examine the interactions between the physical retailer's distribution channel choices and coupon promotions. In normal operation, retailers prefer to pay lower fees to the third-party platform, but we find, counterintuitively, that when carrying on a digital coupon promotion, the retailer can be better off paying a higher participation fee to the third-party platform. We also identify the conditions under which the retailer prefers the third-party platform over the self-operated platform with and without coupon promotions. Furthermore, we show that digital coupon promotions and delivery effort boost the retailer's profits by price discriminating among consumers with differing purchase utilities.     

Coupon Trading and its Impacts on Consumer Purchase and Firm Profits

When a retailer distributes manufacturer coupons to consumers without perfectly identifying their product valuations, consumers may have incentives to trade coupons. We develop a model to capture the coupon trading phenomenon and compare three scenarios: (I) no coupon, (II) coupon without trading, and (III) coupon with trading. We find that coupon trading can increase the profits of either the retailer or the manufacturers, but not at the same time. The retailer benefits from coupon trading when the coupon market is competitive and consumer hassle cost is low, while the manufacturers benefit from coupon trading when the coupon market is uncompetitive and consumer hassle cost is high. In addition, coupon trading does not always increase total demand. Firms benefit from coupon trading by charging higher prices, which leads to a decreased total demand. As a result, consumers end up with a higher average cost under coupon trading. We also compare coupon trading with improved coupon targeting, and find that coupon trading may allow firms to gain higher profits than improved coupon targeting. Further, we extend the main model to a competitive setting where the products are substitutable, and find that the main results still hold. Finally, we employ numerical analysis to identify the optimal coupon face values in different scenarios, and the results suggest that coupon trading combined with incentive mechanisms may lead to Pareto improvement for the channel as a whole.     

Estimating cannibalizing effects of sales promotions: The impact of price cuts and store type

To evaluate the financial impact of supermarket sales promotions, managers must estimate how much new demand comes from cannibalizing the base product compared with other sources. However, investigations into cannibalization are scant. Using vector autoregression analytical framework applied to three years of supermarket scanner data, and sales promotions for pound cake, we estimate cannibalization effects for two common price reductions (10% and 15%), across large, medium and small supermarkets. The sales bumps varied across supermarkets for each price cut while cannibalization effects were substantial only in large supermarkets, with moderate effects in medium stores and no effects in small supermarkets.     

Usage-Based versus Measure-Based Unit Pricing: Is there a Better Index of Value?

In many product categories, unit prices facilitate price comparisons across brands and package sizes; this enables consumers to identify those products that provide the greatest value. However in other product categories, unit prices may be confusing. This is because there are two types of unit pricing, measure-based and usage-based. Measure-based unit prices are what the name implies; price is expressed in cents or dollars per unit of measure (e.g., ounce). Usage-based unit prices, on the other hand, are expressed in terms of cents or dollars per use (e.g., wash load or serving). The results of this study show that in two different product categories (i.e., laundry detergent and dry breakfast cereal), measure-based unit prices reduced consumers’ ability to identify higher value products, but when a usage-based unit price was provided, their ability to identify product value was increased. When provided with both a measure-based and a usage-based unit price, respondents did not perform as well as when they were provided only a usage-based unit price, additional evidence that the measure-based unit price hindered consumers’ comparisons. Finally, the presence of two potential moderators, education about the meaning of the two measures and having to rank order the options in the choice set in terms of value before choosing, did not eliminate these effects.     

Changing Concentration in the Beef and Pork Industries and the Degree of Competition

The four fm concentration level in the beef industry has increased since 1972 and reached 7 1.6% for steers and heifers in 1990. The concentration in the pork industry has been steady except for the last few years. The elasticities of price transmission at the farm to retail level are indicative of competitive market forces for each species. The farm to retail marketing margins have been increasing for both species at an annual rate of 2.88 cents per pound for beef and 5.06 cents per pound for pork. These annual increases do not appear indicative of abusive use of market power by the firms that dominate these sectors when compared with the annual rates of increase for all food items.     

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.     

Competitive location-based mobile coupon targeting strategy

At present, retailers are increasingly targeting consumers based on consumers' geographic locations by distributing mobile coupons. We develop a theoretical model to compare uniform coupon targeting with one-to-one coupon targeting for two competing retailers with asymmetric mobile accessibilities. We find that retailers engage in targeting promotion only when the marginal cost of targeting is not too high. Adopting uniform coupon targeting does not necessarily lead to the prisoner's dilemma. Additionally, the asymmetry of mobile accessibility lessens inter-firm price competition. Finally, our results further demonstrate that marketers should switch from offensive to defensive targeting as the marginal cost of targeting declines.

Return and price volatility of bonds with different credit risk

This article analyzes the relative price and monthly holding period return volatility of bonds with differing credit risk. The research proceeds by decomposing the causes of price volatility into that due to duration and yield volatility. Lower duration, due to higher coupon rate, and relatively stable yields, due to the behavior of credit risk and risk aversion over the business cycle, may well make lower quality issues such as A and Baa industrials exhibit less volatility than high-quality issues such as Aaa industrials and United States Treasury issues.     

Drivers of the synergy between price cuts and store flyer advertising at supermarkets and discounters

Despite retailers’ intense use of both price cuts and store flyer advertising, it is still unclear whether and when it is beneficial for retailers to combine the two promotion tools at the same time as opposed to using them separately. We systematically investigate synergies between price cuts and store flyers for a broad set of 488 brands from 44 consumer packaged goods categories across six leading German retailers. We find that a clear majority of the brands benefit from positive synergies and hence, combining price cuts and store flyer advertising is recommended, especially at supermarkets. This synergy can be strong. For instance, a 15 % price cut without store flyer support at a supermarket, on average, increases sales by 11 %, and medium spending on store flyers for the brand at its regular (non-promoted) price results in a sales lift of 8 %. The combined use of both tools, however, increases sales by 52 %, much more than the sum of their separate effects (11 % + 8 % = 19 %). Yet, there is also substantial variance in the synergy, which we explain with retailer format (supermarkets versus discounters) as well as various brand and category characteristics. Our findings have important implications for the coordination of promotion activities by retailers.     

The framing effect of coupon value for new products: an empirical study in China

Two experiments tested the coupon framing effect with both existing products and new products, whereby the percentage-off format (vs. cents-off format) held an overall advantage in consumers' value perception, thus leading to higher purchase intention. We also found that different product price levels (high vs. low) and product types (physical goods vs. services) moderated this framing effect. Moreover, the context of new products' purchase significantly made this effect more salient than that in existing products. These results could contribute to the guidance of price and promotion strategy for business practitioners, especially in new product launch management.     

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.     

How do restaurant customers make trade-offs among rate fences?

This study examines how restaurant customers make trade-offs among several restaurant rate fences using a sample of mainland Chinese travelers to Hong Kong. A total of six restaurant rate fences (i.e., lunch/dinner pricing, weekday/weekend pricing, table location pricing, restricted coupon pricing, meal period, and reservation and seating policy) and menu price were selected, and a conjoint analysis was performed. Findings reveal that price, restricted coupon pricing, and meal period are the most important attributes when restaurant customers select a restaurant. This study is the first attempt to examine the relative importance of different types of restaurant rate fences. The findings will help restaurant operators to better understand the decision-making process of Chinese travelers and design appropriate rate fences accordingly.
