Effects of distribution channel structure in markets with vertically differentiated products

This study examines how the structure of distribution channels may influence firms’ quality and price strategies and how they may in turn affect consumer welfare. It treats product quality as a decision variable so that the degree of product substitution becomes endogenous rather than exogenous as in previous studies. We find that, with vertically differentiated firms, the changes in channel structure have asymmetric effects depending on whether they occur in the high-quality channel or in the low-quality channel. The product quality of the high-quality channel decreases when it decentralizes unilaterally. However, product quality of the low-quality channel would increase when it decentralizes. The high-quality manufacturer and its channel suffer more from decentralization in comparison with their low-quality counterparts, and the low-quality manufacturer actually receives greater profits when both channels are decentralized. An important driver behind these asymmetries is the interaction between firms’ pricing incentives in integrated versus decentralized channels and what consumer segments they serve. Our analysis indicates that decentralization may reduce consumer welfare, but decentralization in the high-quality channel hurts consumers more than that in the low-quality channel. Therefore in a competitive environment where firms make both quality and price decisions, channel integration would have significant welfare enhancement effects through the elimination of double marginalization, especially if it happens in the high-quality channel. Moreover, we demonstrate that once quality is endogenized, integration is the only equilibrium of channel structure choices. This suggests that the private incentives of firms may actually benefit consumers but do not have to be in line with the general preference of industry regulation for decentralization.     

Pricing and persuasive advertising in a differentiated market

This paper examines the effects of consumer preferences, firms’ costs, and advertising efficiencies on firms’ pricing and persuasive advertising strategies. We show that as the firms’ horizontal differentiation increases, the firm with a lower value-added product tends to increase persuasive advertising, whereas its competitor tends to reduce advertising. Second, the firm receiving a favorable shock in product valuation will complement the favorable change with additional persuasive advertising rather than reduce advertising spending. Third, an equal improvement in advertising efficiency in the industry will lower the profits for both firms, whereas a decrease in advertising efficiency in the industry can benefit both firms. Fourth, a larger shock that improves a firm’s product valuation or unit cost is more likely to induce higher advertising spending in the industry. Lastly, an exogenous increase in the separation between firms’ product valuations or perceived qualities may actually reduce the price dispersion in the industry.     

Valuation and management of money-back guarantee options

In this article, we model money-back guarantees (MBGs) as put options. This use of option theory provides retailers with a framework to optimize the price and the return option independently and under various market conditions. This separation of product price and option value enables retailers to offer an unbundled MBG policy, that is, to allow the customer to choose whether to purchase an MBG option with the product or to buy the product without the MBG but at a lower price. The option value of having an MBG is negatively correlated with the likelihood of product fit and with the opportunity to test the product before purchase, and positively correlated with price and contract duration. Simulation of our model reveals that when customers are highly heterogeneous in their product valuation and probability of need-fit, and if return costs are low, an unbundled MBG policy is optimal. When customers have high likelihood of fit or return costs are excessive, no MBG is the best policy. When customers have small variance in product valuation, but vary greatly in likelihood of product fit, the retailer may prefer to offer a bundled MBG contract, extracting consumer surplus by charging a price close to the valuation level.     

Selling Vertically Differentiated Products under One Roof or Two? A Signaling Model of a Retailer's Roof Policies

Retail firms commonly offer products of different quality levels to serve different consumer segments. In doing so, some firms adopt a “one-roof policy,” selling all of their products in one store, whereas others adopt a “two-roof policy” to better segment consumers, selling high-quality products in a high-end store and low-quality products in a separate, low-end store. Although roof policies are widely practiced and an important aspect of retail management, they are overlooked in the literature and thus not well understood. In this paper, we look at a multi-product retail firm and explore the implications of roof policy for its quality signaling strategies. In our model, the firm carries two vertically differentiated products to serve two consumer segments. We first demonstrate that when product quality is readily observable to consumers, a two-roof policy yields a greater profit than a one-roof policy if the benefit from segmentation outweighs the cost of an additional roof. Then, we assume that a proportion of consumers are uninformed about quality a priori. We show that under both policies, there exists an equilibrium in which the retailer uses both price and in-store services to signal quality. Surprisingly, now there are conditions under which a two-roof policy is outperformed by a one-roof policy, even if the cost of an additional roof is zero. This result sharply contrasts the conventional wisdom that segmentation is optimal as long as its associated marketing cost is low, and suggests the importance of quality information issues in roof policy decisions.     

An empirical analysis of national and local advertising effect on price elasticity

This paper investigates the interaction effect of advertising and price on the market share of a consumer nondurable product. We postulate a model in which local advertising is thought to primarily affect the consumers' purchase by making the demand more price sensitive, and national advertising to affect the consumers' preference, thus making the demand less price sensitive. Moreover, we hypothesize that local advertising interaction will have more immediate effect, while national advertising interaction will have longer term interaction effects. We apply these ideas empirically, and find support for our hypotheses. Thus, the interaction effect of advertising and price can be characterized by both increased and decreased price sensitivity, depending on the type of advertising. Moreover, these effects may be present simultaneously for the same product.     

Welfare and quality improvement in an international market

This paper analyzes the optimal uniform and discriminatory quality requirements under Cournot competition when two firms produce high-quality and low-quality products, respectively, in an international market. The quality requirements in our paper are not set for the foreign firm but are set to regulate products of different qualities, since in the real world a domestic firm could be a high- or low-quality producer. We find that whether the government should raise the quality requirements depends on the type of competition in which firms engage and the adopted quality requirements. By and large, the government should always set quality requirements raising both firms’ quality directly or indirectly, regardless of the quality of the product of the domestic firm. However, if the domestic firm is a high-quality producer, the government should set a quality requirement that enables the domestic firm to monopolize the market when a discriminatory quality requirement is adopted, and should not set any quality requirement when a uniform quality requirement is adopted. Moreover, we show that the quality requirement can actually improve global welfare in most cases.     

De-targeting to signal quality

It is important for firms to signal the high quality of their products to consumers in experience goods markets. Conventional wisdom suggests that a high price can be a signal of high quality. However, we argue that the role of price in signaling quality could be weakened when firms resort to the intensive use of targeting in advertising, which could attenuate the informational content of a high price. As a consequence, a high quality firm needs to distort its price more to signal its quality. However, when different levels of targeting are available, a high quality firm may find it optimal to signal its quality with a lower level of targeting.     

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。     

What reduces product uncertainty in live streaming e-commerce? From a signal consistency perspective

E-commerce live streaming has become a popular emerging trend worldwide. However, as an obstacle to consumer decision-making, product uncertainty is still a concern in e-commerce live streaming contexts. Based on signaling theory and uncertainty literature, we propose that signal consistency can reduce product uncertainty and further facilitate consumers’ purchase intention. Moreover, using a sample of 338 live shoppers, we find that anchor-product fit and live content-product fit negatively affect product quality uncertainty but not product fit uncertainty. Danmaku content-product fit and self-product fit negatively influence product quality uncertainty and product fit uncertainty. Product quality uncertainty positively affects product fit uncertainty, and product quality uncertainty and product fit uncertainty have significant negative effects on purchase intention. Additional analyses suggest that four signal consistency cues and two product uncertainty can be combined in three causal configurations to induce high purchase intention. This study extends relevant theory and literature and guides management decisions for e-commerce live streaming sellers and platforms.     

Consumer perceptions of third party product quality ratings

Consumers increasingly rely on product quality information provided by third-party product ratings organizations. These organizations undertake the task of examining and testing competing products in the marketplace, establishing the level of quality associated with each product, and communicating this information to consumers. Despite the important role of product quality ratings in consumer decisions little research has been conducted to establish the factors which may influence consumer perceptions of these ratings. This paper examines the role of the information content provided by product quality ratings organizations on consumer perceptions. Furthermore, the influence of contextual variables, namely information cost, product category and advertising content, is examined. The results indicate that both content and context significantly influence consumer perceptions of source credibility and their intentions to use the product quality ratings in their purchase decisions.     

Category management,product assortment,and consumer welfare

In this article, we endogenize product assortment decisions under a category management (CM) framework in a channel setup. We find that (1) product assortment is polarized more under CM than under a non-CM regime; (2) the price of a high-end (low-end) product in an assortment increases (decreases) under CM than under a non-CM regime; and (3) a high-quality manufacturer makes more profit than a low-quality manufacturer. In our model, the manufacturer’s choice of quality and its polarization is driven by the existence and the decisions of the retailer (CM or non-CM). Finally, we have an interesting result on consumer welfare. We find that the total consumer welfare, as measured by consumer surplus, worsens under CM only when there is sufficient heterogeneity in consumers’ tastes.     

Designing the content of advertising in a differentiated market

In many markets, consumers use attribute information to assess the value they expect from purchasing a product or service. This includes many low involvement experience goods including take-out food, many packaged good categories and restaurants. In these markets, quality differences exist but many differences are horizontal in nature: the consumer is interested in finding a product that meets her unique tastes. Beyond ensuring that consumers know the brand, the category and the price; it seems advertising should provide consumers with attribute information. However, a significant proportion of advertising does not provide it. In fact, within the same category, competitors respond to messages that emphasize detailed attribute information with messages that are devoid of attribute information. These messages are uninformative about product attributes. We explore how competition in a differentiated market is affected by the ability of a firm has to choose uninformative messages. We construct a model to investigate the factors that affect a firm’s decision to use advertising with detailed attribute information or advertising that does not provide it. The model demonstrates that content decisions about advertising are affected by the differences between products, the range of heterogeneity in consumer tastes and the degree to which costs increase as a function of the quantity of information in advertising. Surprisingly, even when the cost to increase the quantity of information in advertising is low, uninformative campaigns can be more profitable than campaigns with attribute information. The analysis also demonstrates that firms can be more likely to provide attribute information when there are less consumers that are attribute-sensitive. Finally, the model shows that uninformative messages can create “artificial differentiation” in some situations.     

Role of price and quality tiers on the cluster effect in brand choice

This paper examines the moderating role of price and quality tiers on the cluster effect, which postulates that the probability of choosing a brand from a cluster increases with the size of the cluster. Results from two experiments (four product categories in each experiment) show that the cluster effect operates for both high-quality and low-quality brands and that high-quality brands benefit more than low-quality brands.     

Bundling products to success: The influence of complementarity and advertising

This study investigates the strategic influence of product complementarity and advertising on the success of bundling products. We use a profit maximization model to show that when a firm sells bundled products, both the product complementarity and advertising significantly impact the performance of bundled products. The bundling strategy with advertising can help firm achieve higher performance than the bundling strategy without advertising. However, the price discount to the identical products must be attractive to customers and the degree of product complementarity to the complementary products must be large enough, and then the bundling strategy with advertising can obtain a success in the market. Furthermore, our results also show that when the degree of the complementarity between two products increases, firm should invest less on advertising to promote the bundled products. Based on our results, we propose optimal marketing strategies for firms to adopt. Firm managers can utilize our findings to plan their bundling strategies wisely.     

Promoting promotions: Does showcasing free gifts backfire?

Two experiments examine the effect of the visual size of a gift in a free gift promotion on consumer judgments. Results show that promotional offers that highlight the free gift (rather than the product) are less effective than those that highlight the product to be purchased. Increasing the visual size of the free gift leads to perceptions of poorer product quality and has unfavorable consequences for purchase intentions of the offer. We propose that the larger the size of the gift in a promotional ad, the higher the perceived component of gift value in the total promotional offer, and accordingly the lower the value of the promoted product. Therefore, visually larger gifts can backfire and hurt the overall promotional offer. The presence of price information about the product moderates these effects. Implications for the use of visual cues to draw inferences, and managerial implications for advertising free gift offers are discussed.     

The effects of ad heuristic and systematic cues on consumer brand awareness and purchase intention: Investigating the bias effect of heuristic information processing

With growing numbers of digital users, social media advertising becomes a vital marketing channel for attracting and sustaining consumers. Drawing on the heuristic-systematic model, this research investigates the effects of advertisement systematic cues including ad informativeness and ad persuasiveness, and ad heuristic cue which is ad poster category on the consumer brand awareness, and the sequential effect on consumer purchase intention. An experimental design featuring two categories of ad poster, namely, firm and influencer, is created for empirical evidence collection. Results show that ad informativeness and ad persuasiveness contribute to greater consumer brand awareness and purchase intention. The poster category can positively bias the influence of ad informativeness, and firm poster outperforms the influencer poster when controlling the advertisement content the same. The findings demonstrate the co-occurrence of heuristic and systematic information processing in the social media advertising context. This research deepens current understanding of social media advertising and provides practical implications for marketers to capitalize on different ad posters according to advertisement informativeness and persuasiveness feature.     

The effect of product touch information and sale proneness on consumers' responses to price discounts

Since price discounts are costly and can negatively affect consumers' perceptions of quality, it is crucial to identify the factors that make them effective in stimulating purchase behavior. Drawing on cue utilization theory, we examine price discount effectiveness in affecting consumers' reliance on the sale cue based on the provided product touch information as an intrinsic cue and individual consumer differences in sale proneness. Two experimental studies indicate that price discount information, product touch information, and sale proneness interact to determine consumers' responses. Perceived quality is the underlying mechanism behind the observed effects. For nonsale-prone consumers, product touch information favorably influences responses to large price discounts by addressing product quality concerns and enhancing purchase confidence, but has no effect for regularly priced or low discounted products. For sale-prone consumers, product touch information is not effective in increasing their responses regardless of the discount size. A qualitative study provides support for these results and highlights the role of perceived quality and purchase confidence. The research contributes to behavioral pricing, cue utilization theory, and sensory marketing and suggests that marketing managers should provide consumers with product touch information when implementing high discounts for products for which prepurchase touch is important.     

Is brand alliance always beneficial to firms?

In this research, we develop a fresh analytical model to examine the impact of brand quality on the firms’ performances when two firms selling substitute products form a brand alliance. Our results indicate that when two products have equal brand qualities, brand alliance is always a beneficial strategy for two firms to employ. However, when two products have different brand qualities, brand quality differential shows a positive relationship with the profit of the firm with the low-quality brand but demonstrates a negative relationship with the profit of the firm with the high-quality brand in the brand alliance. Our results also show that brand quality differential has a greater effect on the profit of the firm with the high-quality brand than on that of the firm with the low-quality brand. In addition, we find that brand alliance becomes much more valuable to the firm with the high-quality brand when the brand quality differential decreases, but the value of brand alliance has a concave relationship with the profit of the firm with the low-quality brand when the brand quality differential increases.     

Partial carryover of advertising

A model that combines advertising carryover with purchase reinforcement is presented. It accommodates the possibility that certain members of the consumer population rely only on their experience with the product, while others are also affected by past advertising. Empirical results with two product categories indicate that for bimonthly data advertising retention does not exist at all.     

Embodied Product Perception: Effects of Verticality Cues in Advertising and Packaging Design on Consumer Impressions and Price Expectations

As consumers increasingly turn to luxury brands and associated benefits, brand managers face the question how to convey luxury perceptions via marketing communications such as packaging and advertising design. Inspired by theories addressing embodied cognition and symbolic meaning portrayal, this paper argues that visual cues inspiring verticality perceptions (i.e., camera angle and advertising background orientation) affect luxury perceptions and, consequently, consumer evaluations and price expectations. Across three experiments, verticality cues fostered perceptions of product luxury but differentially affected price expectations and purchase considerations depending on product type. Moreover, findings show that effects of vertical orientation are more pronounced for participants high on sociable dominance. Implications of these findings for visual brand management are discussed.
