Online channel strategies under different offline channel power structures

This study explores the manufacturer's marketing and pricing strategies for online channel under different offline channel power structures. Through these strategies, the manufacturer sells products through an offline retailer and an e-tailer. The manufacturer decides the cooperation mode with the e-tailer by the reselling or the agency selling mode and the pricing strategy on the basis of the power structures, i.e., vertical Nash structure (VN), manufacturer Stackelberg structure (MS), and retailer Stackelberg structure (RS). We find the manufacturer selects the online agency selling mode when the commission rate is less than the given threshold. As long as the commission rate is more than another threshold, the manufacturer selects the online reselling mode under the VN structure; however, the manufacturer selects the online agency selling mode under the other two structures. As well, the offline wholesale price is higher under the MS structure than those under the VN and RS structures. When the manufacturer selects the online agency selling mode, the offline retail price is highest under the MS structure, and the online retail price is highest under the VN structure. Meanwhile, consumers can always obtain a higher surplus in the online agency selling mode under all offline power structures.     

Price and quality decisions in a vertically-differentiated supply chain with an “Online-to-Store” channel

Because of the prevalence of “Online-to-Store (OS)” channel, customers can purchase differentiated products online and pick up in-store. We develop a Stackelberg game-theoretic model to study the impact of an OS channel on quality levels, demands, prices, and profits of a manufacturer and a retailer in a supply chain. We assume that the retailer acts as a Stackelberg leader, and the manufacturer acts as a Stackelberg follower. The manufacturer produces and sells two products with vertically-differentiated quality levels to the retailer who in turn sells the products to customers through a Store channel, an Online channel, or an OS channel. The retailer incurs a handing cost if the OS channel is available, and consumers bear a shipping cost and a transaction cost when the products are purchased from the Online and Store channels, respectively. We find that the manufacturer should reduce both products’ quality levels and wholesale prices, whereas the retailer can increase the selling prices for a relatively small shipping cost and a not too small handling cost. When the products are available both online and in-store, however, the quality levels, wholesale prices and selling prices might increase for a small shipping cost and a not too small handling cost. Compared to the case in which both products are available online only with the OS channel, adding the Store channel is always beneficial for both parties. The intuition behind these results hinges on the trade-off between the handling cost and the increased market demand for the retailer. Moreover, the quality levels, the wholesale prices of both products, and the selling price of the low-quality product would decrease, while the selling price of the high-quality product increases for a sufficiently low transaction cost and a not too small shipping cost.     

Expanding to direct channel: Market coverages as entry barrier

A direct marketer can be either a manufacturer selling directly to the final consumers or a retailer that sells an assortment of products from multiple manufacturers. From a manufacturer's point of view, expanding to an online direct channel seems very attractive because intermediaries can be bypassed in reaching final consumers, while the Internet has substantially lowered the entry barrier. With the rapid diffusion of electronic commerce, numerous manufacturers have been considering a direct online channel as an alternative or a supplement to existing retailer channels. However, we observe in the real market that not many manufacturers are fully engaged in online retailing. One major factor frequently mentioned is the conflict with existing dealers who will not be pleased with a manufacturer's attempt to cannibalize their sales. This paper attempts to provide another explanation by comparing theoretical market coverage of manufacturers in a direct channel and a channel with intermediaries. We show that the direct channel can support fewer firms than the traditional retailer channel does, which becomes an effective entry barrier to latecomers. In equilibrium, the products are positively but finitely differentiated in their qualities, and the top two quality tiers would capture more than 75% of the direct channel's market potential (i.e., the “finiteness property”). Thus latecomers would find it difficult to gain a substantial market share against the existing pioneers in the competitive direct market unless they can find other meaningful ways to differentiate horizontally. The sales data of the online retail industry supports our finding.     

How to protect your premium product from low-price competitors: Price,quality, or portfolio adjustment?

In a game-theoretic framework, I analyze how a brand manufacturer can thwart new entrants into its market. Three strategic options are considered, a price adjustment of the premium product, a quality adjustment of the premium product and a portfolio adjustment of adding a fighter brand. In a basic setup, I show that the incumbent's best response to entry is to choose a portfolio adjustment. If, however, the incumbent is uncertain about whether the rival firm will enter the market, a price adjustment of the premium product might be the better alternative if launching the fighter brand is associated with costs. Moreover, if technological progress improves the efficiency of product development, a combined quality and portfolio adjustment might be the best alternative for the incumbent.

随着internet的应用越来越广泛,许多制造商不仅使用传统的销售商渠道销售产品,而且通过网上直销的方式进行产品销售,双渠道增加了渠道之间的竞争。零售商为了在渠道竞争中获得优势,可以通过花费一定的成本增加零售产品价值。通过建立博弈模型分析强势制造商在对零售商信息完全、信息不完全情况下的定价策略,分析得出制造商获得零售商信息的价值,以及零售商愿意向制造商分享成本信息时的临界收益,旨在提出参考建议。     

THE IMPACT OF ORDER FULFILLMENT SERVICE ON RETAILER MERCHANDISING DECISIONS IN THE CONSUMER DURABLES INDUSTRY

Historically, manufacturers held the upper hand in consumer goods supply chain relationships. There has been a pervasive shift of power to retailers over the past 20 years, however, ushering in an era of waning consumer loyalty to manufacturers' brands and increasing loyalty to retailers. While there is extensive research focusing on the manufacturer‐consumer relationship, retailers' increased ability to influence consumer purchases suggests that manufacturers should understand not only consumer perceptions of delivery service, but also retailer perceptions. We incorporate social network theory to examine the manufacturer‐retailer‐consumer linkages in the consumer durables industry, with the emphasis on the retailer in the role of the “broker” (Burt 1992). Specifically, we examine whether retailer perceptions of a manufacturer's order fulfillment service (OFS) positively impacts retailer perceptions of the manufacturer's brand, the importance of the product, and the likelihood of the retailers' salespeople to recommend the product to consumers. The research bridges OFS and retailer purchase behavior in a consumer durables industry characterized by high levels of consumer involvement, brand presence, and personal selling.     

Defensive strategy against a private label: Building brand premium for retailer cooperation

We build a game-theoretic model of price competition between a national brand manufacturer and a retailer that also sells its private label. In particular, we examine a national brand's strategy of building brand premium in the context of channel coordination. The importance of national brand's brand equity has been well-documented in many empirical and behavioral studies. We reinforce the argument that building brand premium should be the first line of defense for a national brand instead of aggressively cutting wholesale price. Not only does the national brand manufacturer benefit from it, but also the retailer who sells both the national brand and its own private label has less incentive to promote the latter. Therefore, it can induce retailer cooperation, which is essential for a successful strategy in a distribution channel.     

Shopping in the omnichannel supply chain under price competition and product return

In recent years, omnichannel retailing has created value for prospective consumers. The rise of omnichannel retailing has changed consumers' buying habits, and manufacturers are facing stiff competition from retailers. To reduce this competition effect, manufacturers and retailers often work together to reduce showroom display costs. Despite this practice, there is little understanding of how omnichannel retailing impacts supply chain (SC) profit under competitive conditions. We investigate the test-in-store-and-buy-online (TSBO) retailing strategy and its impact on SC profit and price competition between manufacturers. The retailer sells products of both manufacturers through its website but displays products of only one manufacturer in the showroom, which bears the displaying cost. The retailer adopts a return policy for the other manufacturer. Stackelberg game was used to examine how members of the chain interact, and Nash equilibrium was used to find optimal strategies for players under decentralized and integrated channels. The results show that the TSBO strategy in retailing benefits all supply chain players under the integrated channel. A further interesting finding is that omnichannel SC profits are highest when retailers adopt a return policy. When two manufacturers compete and adopt different sales models, the manufacturer who uses the TSBO retail model reaps the most profit. Several other managerial insights are drawn from sensitivity analyses.     

Job security,wage bargaining and duopoly outcomes

This paper develops a model where labour supply is constrained because training new workers is costly and redundant workers cannot be fired. An entrant draws labour from an incumbent firm through a wage contest while wages in the latter are bargained with its unionized workers. In a Cournot equilibrium, the union's bargaining power has a positive effect on the incumbent's output, but a negative effect on the industry output. Social welfare under duopoly may fall short of the monopoly level. The distribution of bargaining gains within the incumbent firm is sensitive to whether wage and output choices are made sequentially or simultaneously.     

Optimal retail sales strategies for old and new products in monopoly and horizontal competition scenarios

Advances in technology have made product updates more frequent and allowed consumers to choose different versions of the same product based on their preferences. It is crucial for retailers to understand how to formulate optimal sales strategies based on those different consumer preferences. To this end, we develop game models that consider the heterogeneity of consumer preferences under both monopoly and horizontal competition scenarios and perform the sensitivity analysis to examine the impact of consumer proportions and consumer preferences on retailers’ sales strategies. The results show that (i) regardless of competition or monopoly status, the original retailer can always maximize profit by setting prices based on the market share of traditional consumers, as long as the retailer sells both new and old versions of the product; (ii) the greater the competitive advantage of the competitor, the more advantageous the hybrid sales mode; (iii) if the price of the old product is below a certain threshold, there will be a positive profit for the original retailer when selling both the old and new products; and (iv) when consumer acceptance of competing retailers is lower, entering the retail market is not a good choice for competing retailers.     

How incumbent firms foster consumer expectations, delay launch but still win the markets for next generation products

Consumers learn quality of many durable products through word-of-mouth information while firms launch new and improved products frequently in these markets. This paper examines firm incentives to invest in R&D to compete for patents in makets where consumers rely on word-of-mouth information and have expectations about the new products before launch. When its loss due to a possible entry is above a threshold, an incumbent has more incentives than a potential entrant to invest in R&D for patents. Moreover, if the current product is more profitable, its true quality is above consumer priors and the quality of the new product is below a threshold, it is optimal for the incumbent to launch the new product after a time lag. The later the optimal time of launch, the greater is the incumbent’s potential loss if entry occurs and greater its incentives is to invest in R&D versus that of the entrants. While potential entrants are generally thought to have more incentives to invest in a drastic innovation which results in a race to launch the new products, we show that the more drastic the innovation, the later the optimal time of launch and greater are the incumbent’s incentives to invest in R&D when the value added of the new product can be conveyed to all the consumers. Only when consumers are uncertain about the value added of the new product, the incumbent’s incentives are lower. We also demonstrate that by promoting consumer expectations about the new product before launch, an incumbent has more time to launch and higher probability of dominating its market.     

Entry deterrence/accommodation with imperfect strategic thinking capability

Both through empirical research and laboratory experiments it has been shown that managers are heterogeneous in strategic thinking-i.e., not all the managers can accurately conjecture their competitors’ behavior and actions. In this paper, we examine the entry deterrence/accommodation strategy of an incumbent firm facing a potential entrant that may behave less strategically than the incumbent in the way of conjecturing competitors’ actions and beliefs. We adapt the Cognitive Hierarchy model to capture this heterogeneity among the managers of the entrant firm and the incumbent firm. Surprisingly, we show that the incumbent can deter entry by investing in expanding the market size and the competition may increase the incumbent’s incentive to invest in market expansion. If entry does occur, the market expansion in our model also benefits entrant comparing to the case without market expansion. This feature of our result sets it apart from the standard result in the entry deterrence literature, which tends to suggest that incumbent has to either over-invest in actions harmful to entrant if entry occurs. In our model investing in expanding the market size makes the entrant to update its belief about the incumbent’s strategic thinking capability downward and thus, decreases the entrant’s expected profitability, which in turn deters entry. Our research has important implications especially for emerging markets given that the lack of management talent is a particularly severe problem among local firms in emerging markets and multinational companies pioneer in the emerging markets with great market expansion opportunities have to face the potential entry of local companies.     

Flirting with the enemy: online competitor referral and entry-deterrence

Internet retailers often compete fiercely for consumers through expensive marketing efforts like search engine advertising, online coupons and a variety of special deals. Against this background, it is somewhat puzzling that many online retailers have recently begun referring their website visitors to their direct competitors. In this paper, using an analytical model, we examine this counterintuitive practice and posit that an entry deterrence motive can potentially explain this marketplace puzzle. Specifically, we develop a model where two incumbents compete for consumers” business while facing a potential entrant who is deciding whether to enter the market. In addition to setting the price, each incumbent firm could potentially display a referral link to its direct competitor. Our analysis reveals that when confronted with a potential entry, an incumbent may refer consumers to its competitor, intensifying the market competition that could result in shutting off the entrant. Furthermore, we show that when referral efficiency is exogenous, it is possible that in equilibrium only one incumbent refers its customers to competitor (i.e., one-way referral) or both incumbents refer their customers to each other (i.e, two-way referral). When referral efficiency is endogenous, the ex-ante symmetric incumbents may choose asymmetric referral efficiencies ex-post. We extend the model in a number of directions including making the entrant share endogenous and allowing incumbents to be asymmetric. Overall, our results indicate that firms may be motivated by entry deterrence to voluntarily refer consumers to their direct competitors even when they are paid nothing for the referral.     

Local competition, entry, and agglomeration

This paper analyzes competition between two spatially differentiated multi-product retailers who encounter entry from a low-cost discounter. We assess how entry affects the pricing of the incumbent stores and the role played by the location of the entrant. Our primary objective is to identify how traditional retailers respond to new forms of low-cost retailing. Results show that post entry, the prices for some products are higher than the pre entry. However, which product prices increase depends on the incumbent’s location. Contrary to conventional wisdom, we find that the store closer to the entrant is better off compared to the incumbent located further away. We empirically demonstrate the main workings of our theory using sales data from several grocery stores that saw entry by discount stores in their trading areas.     

Retailer voluntary investment against a threat of manufacturer encroachment

To elucidate supply chain cooperation between a manufacturer and a retailer, this study examines a model in which the retailer makes voluntary investments to reduce the marginal production cost of the manufacturer. The manufacturer is allowed to introduce a direct selling channel in addition to the indirect channel through the retailer (i.e., manufacturer encroachment), which however dampens the retailers’ investment incentives. The retailer can leverage its voluntary investments as a means of deterring manufacturer encroachment. We demonstrate that manufacturer encroachment is strategically deterred when the retailer’s cost-reduction technology is sufficiently effective. This strategic encroachment deterrence encourages the retailer to invest more, but it narrows the variety of channels from which consumers can select. When the latter effect dominates the former effect, consumer surplus declines with strategic encroachment deterrence.

     

Retailer Heterogeneity,Intra-Brand Competition and Social Welfare

This paper considers a model where a manufacturer sells its product to consumers through competitive retailers who are heterogeneous in marginal distribution costs and geographic locations. We study the welfare implications of resale price maintenance (RPM), which eliminates the intra-brand competition. We show that with RPM, the manufacturer can make more profit at the cost of the consumers. RPM helps the high-cost retailers to stay competitive in the market, and therefore increases the total distribution cost of the society. We suggest that antitrust authorities should be concerned when intra-brand competition is lessened.     

Store Brand Quality and Retailer’s Product Line Design

This study analyzes a retailer’s store brand quality decision in vertically differentiated product categories. We analyze a game theoretic model composed of one or two national brand manufacturers and a retailer, who strategically chooses the quality level(s) of its store brand(s) relative to the well-established national brand position(s) to maximize its category profit. Our analysis reveals that the nature of a retailer’s store brand quality positioning is quite different from the manufacturer’s national brand positioning decision, and that the best position for a store brand is not “as close to a national brand as possible” as previous studies suggest. Instead, the optimal quality position of each store brand is remarkably sensitive to the distribution of consumers’ willingness-to-pay. In particular, the relative proportions of quality sensitive consumers and price sensitive consumers determine the balance of three key strategic forces — the market expansion force, the retail margin force, and the consumer profitability force, leading to different optimal product line designs for store brands across different category environments. Interestingly, against multiple incumbent national brands, the retailer’s optimal product line design includes a store brand positioned at the highest quality level in the category only if most consumers are moderately quality conscious. We also analyze the implications of national brands’ brand equity for retailers’ store brand strategy.     

Empirical investigation of channel reactions to brand introductions

We investigate how incumbent manufacturers and retailers alter their pricing behavior in response to new product introduction. In performing our analysis, we need to be cognizant of the fact that the observed price changes can be due to entry-induced changes in a) demand conditions or b) costs or, on the other hand, to the competitive behavior of c) manufacturers and/or d) the retailer. In order to separate these four changes, we posit that manufacturer and retailer pricing is an outcome of maximizing a combination of shares and profits. This enhanced objective function allows us to measure competitive conduct benchmarked as less or more competitive than under the Bertrand-Nash framework. Our empirical analysis is based on the toothpaste category for the time period January 1993–February 1995. During this period, there were three brand introductions in two rounds of entry. Using the estimates from the demand and the supply model, we compute the changes in the retail and wholesale prices that are attributable to changes in demand conditions, manufacturer and retailer competitive conduct, and cost changes. These results support our conjecture that inferring the change in conduct solely based on a change in observed prices is likely to be erroneous. For the first new brand entry, we find that the brand introduction did not significantly increase competition between manufacturers. As a result, the balance of channel power between the manufacturers and the retailers remained unaltered. Both retailer and manufacturer profit margins increased after the first entry. However, subsequent to the second entry, retailer share of channel profits increased at the expense of the manufacturers; manufacturers even saw a decline in their absolute profit margins. We believe that this research will provide insight for manufacturers and retailers regarding how the various channel participants are likely to react to new product introduction. Furthermore, policymakers interested in understanding competitive reactions to new product introduction should find this research useful.     

Dynamic assortment in the presence of brand heterogeneity

In this paper, we study the dynamic assortment planning problem in the presence of heterogeneous brands. Over a limited selling season, the retailer sells heterogeneous products from one store brand and one national brand. We use the nested multinomial logit (NMNL) framework to model consumer choice process, in which consumers choose first which brand to buy and then a product within that brand. We formulate this problem using the finite-horizon dynamic programming approach. Using available sales transaction data, we estimate the consumer choice behavior and empirically demonstrate existence of brand heterogeneity. Further, our results suggest that ignoring brand heterogeneity will make the retailer’s expected revenues significantly overestimated, and the potential revenue overestimation depends on initial inventories and prices of products of two brands. We finally show that the retailer will benefit from dynamic assortment optimization with the estimated consumer choice model.     

Brand and quality effects on introduction of store brand products

This paper considers a supply chain with a single manufacturer selling a national brand product via a single retailer. The retailer has the option to introduce a product under his own brand into the market with the same functionality as the national brand product. We simultaneously consider the consumer bases of the national brand and store brand along with consumers' willingness to pay for quality and the supply chain control (centralized vs. decentralized). By analyzing the game-theoretic models, we offer managerial insights about the influences of brands' consumer bases on the quality and pricing decisions of the retailer, and on the manufacturer's willingness-to-collaborate when the retailer introduces the store brand product. We find that, although it is usually easier for the retailer to introduce a product under a store brand with a large consumer base, doing so with manufacturers of well established national brands can be difficult, when the retailer often has to greatly mark down his store brand product's quality and price. We also find that a store brand product with a small consumer base shall be launched only when the supply chain is switched to a centralized control and when the manufacturer's national brand has a large consumer base. These important findings offer guidance to both national brand manufacturers and retail store managers regarding the launch of store brand products.
