How a novel option contract helps a green product to enter a traditional product's retailing channel: A mathematical modeling approach

Multi-sourcing is a practical strategy in retail channels that allows retailers facing uncertainties to respond more effectively to consumers' needs by distributing market demand across multiple supply sources. In this respect, this research investigates a price-setting retailing channel, including two manufacturers (a traditional manufacturer and a green manufacturer) and one retailer where end-of-life products can be collected. The retailer faces an uncertain price-dependent demand and sets orders from both supply directions based on a low-cost ordering approach. The primary purpose of this study is to develop an optimal solution to allow the green product to enter the retailing channel of the non-green product. Accordingly, this research develops and compares two different contractual mechanisms from the standpoint of the green manufacturer/retailer and the supply chain (SC): (1) a penalty-based contract and (2) a modified call option contract mixed with a cost-sharing mechanism. The main contribution of the current paper is to investigate an option contract for the effective management of a closed-loop supply chain and combine it with a cost-sharing contract as a new approach. Another contribution is that the developed model considers two practical channels for collecting and returning obsolete products to the green manufacturer: (1) the retailer is responsible for collecting and returning obsolete products, and (2) collecting and returning obsolete products is outsourced to a third-party logistics provider (3PL). Eventually, the models' efficiency is verified by investigating different numerical experiments, discovering that the proposed reservation-based contract outperforms the penalty-based contract for both parties' profitability and retailing channel's improvement. Besides, the present study finds that hiring 3PL significantly increases the green manufacturer's profit compared to other scenarios.     

努力水平影响需求的供应链收入共享契约研究

考虑由一个供应商和一个零售商组成的二级供应链,其中需求是随机的且受零售商的销售努力水平影响。在销售季节前,零售商需要同时确定订购数量和相应的销售努力水平。在分散式供应链环境下,通过分析传统的收入共享契约无法协调供应链的原因,提出基于成本共担的收入共享契约模型,证明当努力水平影响方式为积的形式时,基于成本共担的收入共享契约能有效协调供应链。     

Do channel members value the multiple-cooperation strategy?

When the manufacturer distributes his products through online and traditional channels, what type of innovative marketing strategy can be utilized to solve the channel conflict and improve the performances of all channel members? Our research addresses this important question by initiating a triple cooperative strategy for channel members to employ in a manufacturer – retailer dual-channel supply chain. Our results show that when the product is less compatible with online channel than with traditional channel, channel members can utilize a triple cooperative strategy to improve channel coordination and their individual performances effectively and efficiently. First, the manufacturer can utilize supportive retail sales effort as a valuable coordination mechanism to improve the performances of all channel members in the dual-channel distribution. Second, a channel coordinative price strategy can be utilized to further improve the performance of whole channel. Finally, a profit sharing mechanism is needed to create a Pareto result for both the manufacturer and the retailer. Furthermore, we extend our model to study the value of triple cooperative strategy in a manufacturer – two competitive retailers supply chain and derive the optimum marketing strategy.     

Cooperative game analysis of coordination mechanisms under fairness concerns of a green retailer

This study discusses how a green retailer's fairness concerns affect product greenness and profit and explores how to distribute surplus profits under the fairness concerns using cooperative game theory. Research findings indicate that cooperation contributes to increasing channel profits and improving product greenness, but the fairness concerns are detrimental to them. The three proposed coordination mechanisms (SVM, NSM, and TVM) are feasible to ensure coalition stability, but their beneficiaries differ. NSM benefits a manufacturer, while SVM benefits retailers. Additionally, the green retailer's fairness concerns serve as distribution tools to narrow profit gaps between the manufacturer and the green retailer.     

Decomposing the effect of advertising: What happens in the retail channel?

The diverging interests of manufacturers and retailers famously give rise to the double marginalization problem but have consequences far beyond pricing. Advertising is another marketing instrument that is under the control of the manufacturer but its ultimate effect on consumer demand also depends on retailers’ pricing decisions. We decompose the effect of advertising in the channel and highlight an additional route through which advertising affects sales, namely via the changes in the retail price that a strategic retailer makes in response to changes in demand following manufacturer advertising. The total demand effect of advertising thus comprises the direct effects of advertising on market shares, and the indirect effects coming through adjustments that the retailer makes to the in-store prices of all the brands in a given product category in response to the shifted demand due to advertising. We match advertising data for four different categories (both food and non-food) to store-level scanner panel data, which also include information on wholesale prices. Controlling for wholesale prices, we establish in a reduced-form model that the retailer reacts to manufacturer advertising by changing retail prices instead of simply imposing a constant markup on the wholesale price. To further explore the role of the strategic response of the retailer in a systematic fashion and quantify the effects derived in the decomposition, we estimate a discrete-choice model of demand and determine the magnitude of the direct and indirect effects. We find that the indirect effect of advertising through retailer prices is about half the size of the direct effect, and thus substantively affects advertising effectiveness.     

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.     

Why would a big retailer refuse to collaborate on manufacturer SPIFF programs?

Big retailers that carry a large assortment of products rely on knowledgeable salespeople to provide purchase advice to customers and match customers with suitable products. Interestingly, big retailers vary in their policies regarding whether to allow their salespeople to receive manufacturer SPIFF (Sales Person Incentive Funding Formula) payments, which motivate salespeople advising at no cost of the retailer. In this study, we investigate a big retailer’s incentive to block manufacturer SPIFF programs, which has the consequence of demotivating salespeople from advising customers, from the perspective of vertical channel interactions. We scrutinize a big retailer’s decision to maximize its profit through managing its channel interactions with upstream manufacturers offering horizontally differentiated products, customers uncertain about true fits with competing products, and its salesperson who can match customers with suitable products through offering purchase advice. Our analysis shows that motivating the salesperson to advise customers is profitable for the retailer only if the such advising has moderate effectiveness in matching consumers and suitable products, and only in this case would the retailer collaborate on manufacturer SPIFF programs. Otherwise, salesperson advising hurts retailer profit and the big retailer benefits from blocking manufacturer SPIFF programs. Our study reveals the interesting theoretical insight that the incentives of a big retailer and upstream manufacturers to motivate sales advising reside in their incentives to battle for a more favorable channel status.     

Promotional Framing of Green Products: Mediating Role of Sale Proneness

Abstract

The impact of sales promotion in boosting short-term sales is well established in the literature. While there are ample studies on the impact of sales promotion on conventional products in western countries, there is very scant research on the effect of promotions on green products and almost nonexistence research in emerging economies. This research addresses this gap by doing a comparative assessment of economically equivalent bonus pack sales promotion and price discount sales promotions on green versus non-green products through two experiments designed as a 2 (green product motivation: hedonic vs. utilitarian) × 2 (promotional frame: price discount vs. bonus pack) × 2 (discount level: low vs. high) between-subjects study, and 2 ( product types: green, non-green/control) × 2(promotional frame: price discount, bonus pack) between-subjects study. This research further examines the mediating role of sale proneness in the purchase process. The findings of this research indicate that buyers' preferences for promotion are quite varied for the purchase of green versus non-green products, and the price discount increases sale proneness which exerts a negative impact on product purchase willingness. Accordingly, this study has some theoretical and practical implications.     

Distribution Channel Decentralization and Strategic Durability Choice

In a simple two‐period setting we examine a decentralized distribution (marketing) channel consisting of an up‐stream durable‐goods manufacturer and down‐stream retailer. The manufacturer sets the wholesale price and the product’s durability while the retailer selects an output level. We show that in this setting, the profit‐maximizing manufacturer unambiguously selects a higher durability than the socially efficient (cost‐minimizing) level in both uncommitted sales and rental markets. We show this ‘reversed planned obsolescence’ result is due to the strategic benefit of durability in this double‐marginalization (double monopoly mark‐up) setting. This is in stark contrast to the usual integrated channel result where the profit‐maximizing manufacturer will select an efficient level of durability in rental markets and an inefficiently low durability in uncommitted sales markets (due to the selling firm’s commitment problem with potential buyers). Intuitively, with a decentralized distribution channel, the manufacturer faces potential commitment problems with both current buyers and its down‐stream retailer. We show, only in cases where both sources of commitment issues are removed (i.e. the manufacturer can credibly commit to both potential buyers and its retailer), will the profit‐maximizing durability choice be socially efficient.     

基于需求与储量相关条件下的供应链协调研究

供应链模型由一个制造商和零售商组成,其中制造商向零售商供应商品,零售商面临客户的商品需求与储量相关。在该模型中,制造商欲通过批发价和储量成本补偿方式来协调分散式供应链并赢利,使供应链分散式时的系统总储量等于集中控制时的储量水平。假定商品需求是依赖储量的函数和一个储量成本补偿。在单个零售商情形下,制造商需要增大批发价及支付给零售商的储量成本补贴来协调整个渠道并盈利。当两个及多个零售商竞争时,假定市场需求依赖于总储量水平,零售商按照储量比例分割市场。     

信息共享下双渠道制造商与零售商协调研究

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。     

Retail services and firm profit in a dual-channel market

With the rapid development of the Internet, many manufacturers nowadays use online technology to engage in direct sales. The mix of retailing with a direct channel adds a new dimension of competition and complementarity to a product's distribution channels. Our model focuses on the strategic role played by the retail services in a dual-channel competitive market. The manufacturer uses a direct channel as an effective tool to motivate the retailer to improve its retail services and profits from it. While operated by the manufacturer to motivate retailer to perform more effectively from the manufacturer's perspective, the direct channel may not always be detrimental to the retailer because the retailer can obtain a lower wholesale price from the manufacturer and a higher sales volume from the improved retail services. In our research, our results suggest that the improved retail services effectively alleviate the channel competition and conflict and improve the supply chain performance in a competitive market.     

基于促销投资的非对称信息供应链契约研究

利用了委托代理理论和最优控制理论,分析对称信息和不对称信息两种情况下制造商和零售商的供应链契约。零售商进行促销投资,在对称信息情况下,制造商以批发价作为线性契约来协调供应链系统,批发价是促销投资的减函数;在非对称信息情况下,制造商以批发价和补贴作为非线性契约的协调机制,而批发价和补贴都是促销投资的增函数。     

Ownership coordination in a channel: Incentives,returns, and negotiations

In many industries firms have to make quantity decisions before knowing the exact state of demand. In such cases, channel members have to decide which firm will own the units until demand uncertainty is resolved. The decision about who should retain ownership depends on the balance of benefit and risk to each member. Ownership, after all, is costly. Whichever member owns the units accepts the risk of loss if more units are produced than can be sold. But ownership also grants firms the flexibility to respond to demand once it becomes known by adjusting price. In this study, we analyze ownership decisions in distribution channels and how those decisions are affected by demand uncertainty. We model demand based on micro-modeling of consumer utility functions and capture demand uncertainty related to market size and price sensitivity. This study shows that as long as the degree of uncertainty about market size is intermediate, the retailer and the manufacturer both benefit when the manufacturer maintains ownership of the units. But when there is substantial uncertainty about market size, the retailer and the channel are better off if the retailer takes ownership but the manufacturer still prefers to maintain ownership. Thus, there is potential for channel conflict regarding ownership under high levels of uncertainty. We show that, using product returns, the manufacturer can achieve the same outcome under retailer ownership as under manufacturer ownership. This provides an additional new rationale for the prevalence of product returns. The first-best outcome (from the perspective of total channel profit), however, is under retailer ownership without product returns when uncertainty is high (i.e., product returns reduce the total channel profit). Negotiations between the manufacturer and the retailer can lead to the first-best outcome but only under quite restrictive constraints that include direct side payments by the retailer to the manufacturer and the retailer being pessimistic about its outside option (when an agreement cannot be reached) during the negotiation.     

Managing advertising investments in marketing channels

This paper investigates how should manufacturers optimally allocate resources to retailer-initiated (retailer) advertising through cooperative advertising programs and own (manufacturer) advertising in a bilateral monopoly. Retailer advertising stimulates immediate sales but may also harm long-term (post-advertising) demand, whereas manufacturer advertising aims at building brand equity and stimulates both immediate and long-term sales. A game-theoretic model in which a manufacturer and a retailer set pricing and advertising decisions over a two-period planning horizon is developed to account for the differences between manufacturer and retailer advertising. We characterize equilibrium solutions for four advertising scenarios for the manufacturer, ranging from no investment in any advertising activity to undertaking own advertising and supporting retailer advertising simultaneously. Comparing the two players’ equilibrium strategies and profits across these scenarios, we find that manufacturers should avoid offering exclusively cooperative advertising programs to retailers. When retailer advertising positively influences long-term sales, manufacturers should offer cooperative advertising supports to retailers in addition to undertaking their own advertising. When retailer advertising negatively affects long-term sales, manufacturers can still undertake own advertising and offer cooperative advertising under certain conditions. However, if these conditions are not met, focusing exclusively on own advertising is their best advertising strategy. Retailers also prefer scenarios in which manufacturers advertise, but may choose not to participate in manufacturers’ cooperative advertising programs. This leads to suboptimal outcomes if cooperative advertising programs are not enhanced by additional incentives (e.g., side payments or other services).     

Perceptions of price (un)fairness in a channel context

This article extends prior research on perceptions of price (un)fairness by attempting to disentangle where in the marketing channel (un)fairness inferences lie. Extant research in this area overwhelmingly considers (un)fairness perceptions with respect to the pricing action only, ignoring attributions aimed at specific channel actors. This article illustrates differences in (un)fairness inferences with respect to retailers and manufacturers given price increases accompanied by decreased product supply, increased demand, or increased variable costs. We show that a retailer is considered relatively more unfair than a manufacturer given a price increase accompanied by a demand increase, as well as when no explicit reason is given for the price increase. Conversely, a manufacturer is considered relatively more unfair given a price increase accompanied by a supply decrease. Both channel entities are considered equally fair given a price increase accompanied by a channel (both retailer and manufacturer) or manufacturer cost increase, while a retailer is deemed relatively more unfair given a price increase accompanied by a retailer cost increase. This research generally suggests that inferences of causality for specific pricing actions may differentially skew toward upstream or downstream channel entities depending on the particular economic circumstances of the price change.     

Strategic Decentralization and Channel Coordination

In this paper, we show that under certain conditions, strategic decentralization through the addition of a retailer in the distribution channel can increase a manufacturer's profits. The specific case on which we focus is the quantity coordination (double marginalization) problem for a manufacturer selling durable goods in a two-period setting. We show that the standard solution that coordinates a channel for non-durables does not coordinate the channel for durables. In particular, even though a manufacturer can achieve channel coordination by offering per-period, two-part fees, the equilibrium wholesale price in the first period is strictly above the manufacturer's marginal cost. This is in stark contrast to the two-part solution for non-durables where the equilibrium wholesale price is equal to marginal cost. We also identify a strategy that solves both the channel coordination and the Coase problem associated with durable goods. In this strategy, at the beginning of period 1, the manufacturer writes a contract with the retailer specifying a fixed fee and wholesale prices covering both periods. We show that by adding a retailer and using this contract, the manufacturer makes higher profits than it could if it were to sell directly to consumers.     

Efficient replenishment in the distribution channel

Efficient replenishment (ER), a business process that involves the reduction of order cost to facilitate deliveries of goods from the manufacturer to the retailer, is becoming increasingly important in distribution channel management. While a well-executed ER program is expected to lower total channel costs and increase channel profit, very little is known about how this incremental channel profit is distributed between the manufacturer and the retailer and how it varies across the two common channel relationship structures, retailer price leadership and manufacturer price leadership.In this paper, we develop the conditions under which the manufacturer and the retailer gain more or less from the adoption of ER based on a game theoretic channel model of bilateral monopoly under the two channel relationship structures. We develop analytic results on the impact of ER on purchase quantity, price and the distribution of profits in three cases, namely, (1) when only the retailer adopts ER, (2) when both the manufacturer and the retailer adopt ER, and (3) when the manufacturer and the retailer are vertically integrated in the distribution channel, which adopts ER.The results, which can be generalized for all demand functions, show that the manufacturer benefits from the retailer's adoption of ER only when the manufacturer's holding cost relative to the retailer's is sufficiently large, relative to its order cost relative to the retailer's. By adopting ER, the retailer gains more than what the manufacturer gains even if the manufacturer is the price leader. Both the parties are likely to gain more if they both adopt ER than if only the retailer adopts ER. The incremental channel profit due to the retailer's ER adoption is highest in a vertically integrated distribution channel and is greater in a retailer-led channel relationship than in a manufacturer-led relationship.     

On manufacturers complementing the traditional retail channel with a direct online channel

With the explosion of the Internet and the reach that it affords, many manufacturers have complemented their existing retail channels with an online channel, which allows them to sell directly to their consumers. Interestingly, there is a significant variation within product categories in manufacturer's use of the Internet as a direct distribution channel. The main objective of this study is to examine the strategic forces that may influence the manufacturer's decision to complement the retail channel with a direct online channel. In particular, we are interested in answering the following questions:

1. Why is it that in some markets only a few firms find it optimal to complement their retail channels with a direct Internet channel while other firms do not?
2. What strategic role (if any), does the direct Internet channel serve and how do market characteristics impact this role?

To address these issues we develop a model with a single strategic manufacturer serving a market through a single strategic retailer. In addition to the focal manufacturer's product the retailer carries products of competing manufacturers. Consumers in this market are one of two types. They are either brand loyal or store loyal. The retailer sets the retail price and the level of retail support, which impact the demand for the manufacturer's product. The retailer's decisions in turn depend on the wholesale price as well as the Internet price of the product if the manufacturer decides to complement the retail channel with an online channel. Our analysis reveals that the optimality of complementing the retail channel with an online channel and the role served by the latter depends critically upon the level of support that the retailer allocates to the manufacturer's product in the absence of the online channel. The level of support allocated by the retailer, in the absence of the online channel, depends upon the retail margins on the manufacturer's product relative to that on rival products in the product category. When the size of the brand loyal segment is small relative to the size of the store loyal segment then in the absence of the online channel, the manufacturer can lower wholesale price and enhance retail support, especially when the retail margins on the rival products are low. In contrast, when the size of the loyal segment is large and the retail margins on rival products are high the manufacturer will find it more profitable to charge a high wholesale price even if that induces the retailer to extend low levels of support. If the manufacturer decides to complement the retail channel with an online channel, some consumers who would have purchased from the retailer might prefer to purchase online. Our analysis reveals that when consumers' sensitivity to price differences across the competing channels exceeds a certain threshold it is not optimal for the manufacturer to complement the retail channel with an online channel. However, this price sensitivity threshold itself depends upon product/market characteristics, suggesting that manufacturers seeking to complement their retail channels with an online channel should look beyond the nature of threat the online channel poses to the retail channel in devising their optimal distribution strategies. When the retail margins on rival products are sufficiently small, complementing the retail channel with an online channel when optimal allows the manufacturer to price discriminate and enhance profits. In contrast when retail margins on rival products are sufficiently high, complementing the retail channel with an online channel serves to enhance retail support. We also identify market conditions under which profits of both the manufacturer and the retailer are greater with the online channel than that without it. This is particularly interesting since the online channel competes with the retail channel.     

Pure Components versus Pure Bundling in a Marketing Channel

This paper examines how channel interactions influence product bundling decisions by channel members. Specifically, what products or bundles should be offered, at what prices, and by which channel members, in equilibrium. To answer this, we analyze Stackelberg games between a manufacturer and retailer, with pricing and bundling as decision variables, under discrete and uniform continuous distributions of reservation prices. We find that selling pure components by both manufacturer and retailer is the equilibrium except in a narrow region of the parameter space. However, if the manufacturer can sell bundles and prevent unbundling, then such a bundling strategy is optimal in many cases. Interestingly, the channel and retailer also benefit from this strategy.
