引入风险厌恶偏好的供应链部分回购协调契约

研究了由一个风险中性的供应商和一个风险厌恶的零售商组成的供应链系统的部分回购契约。将部分回购契约建模讨论,并进行数值模拟分析。结果表明,当零售商为风险厌恶时,供应链系统仍能达到协调,且回购比例是零售商的风险厌恶程度的增函数,批发价格是零售商的风险厌恶程度的减函数。     

The Profit‐Maximizing Case for Corporate Social Responsibility in a Bilateral Monopoly

We analyze a stylized distribution channel (bilateral monopoly) model where an upstream manufacturer sells output to a downstream retailer. In a two‐stage linear demand game setting, we show that a two‐part contract, consisting of a wholesale price and corporate social responsibility (CSR) component, can be utilized by the manufacturer to fully coordinate and control its retailer. Thus, a CSR contract can be used in place of the traditional two‐part tariff scheme (wholesale price and fixed franchise fee) to optimally coordinate the marketing channel. Our model provides a novel theoretical profit‐maximizing rationale for the strategic use of CSR. Copyright © 2013 John Wiley & Sons, Ltd.     

Decentralized Supply Chain Decisions on Lead Time Quote and Pricing with a Risk‐averse Supplier

We consider a decentralized supply chain containing a risk‐averse supplier and a risk‐neutral retailer with lead time‐sensitive and price‐sensitive demands. A Stackelberg game is employed to model the lead time quote and pricing decision process between the two members under the conditional value‐at‐risk criterion. A unique equilibrium is obtained. Using the corresponding centralized mode as a benchmark, we find that a less risk‐averse supplier is better to cooperate and share risk with the retailer to improve the entire supply chain's efficiency. With a uniformly distributed realized lead time, the impact of the supplier's risk aversion on the decisions can be characterized by a few threshold values of the late delivery penalty cost. In particular, when the unit delay penalty cost exceeds a certain level, a more risk‐averse supplier will counter‐intuitively quote a shorter lead time by risking a higher delay penalty cost.

本文从零售商的角度,首先分析了零售商自身利润最大化的分散式决策,然后分别研究了供应链系统利润最大化、供应商和零售商联盟下的渠道利润最大化的集中式决策模型。进而提出了与展示量和零售价格相关的批发价加补贴合同,得到协调零售商的分散式决策,达到与系统利润最大化决策一致的结果。     

基于库存调剂的易逝品供应链合作利益分配问题探讨

本文将解决多人合作博弈问题的Shapley值方法用于解决两级易逝品供应链合作利益分配问题。考虑由一个供应商和两个零售商所组成的两级供应链模型,零售商与供应商不合作时,零售商根据供应商的批发价确定订货量,合作时共同决定库存,零售商之间的合作为共同决定订货量且通过库存调剂(转运)共享库存,三方合作可获最大利益,采用Shapley值法可合理分配合作利益,从而使合作更稳定。     

Bait and ditch: Consumer naïveté and salesforce incentives

We analyze a model of price competition between a transparent retailer and a deceptive one in a market where a fraction of consumers is naïve. The transparent retailer is an independent shop managed by its owner. The deceptive retailer belongs to a chain and is operated by a manager. The two retailers sell an identical base product, but the deceptive one also offers an add‐on. Rational consumers never consider buying the add‐on while naïve ones can be “talked” into buying it. By offering the manager a contract that pushes him to never sell the base good without the add‐on, the chain can induce an equilibrium in which both retailers obtain more‐than‐competitive profits. The equilibrium features price dispersion and market segmentation, with the deceptive retailer targeting only naïve consumers whereas the transparent retailer serves only rational ones.     

基于Stackelberg博弈的供应链信用风险分析

讨论了由一个供应商和一个销售商组成的简单供应链,在销售商还款不确定的前提下,基于供应商和销售商订货过程是Stackelberg博弈,给出了他们的最优定价和订货策略,并说明了通过合理定价,供应商可以有效地防范信用风险;然后分析了销售商违约对供销双方及供应链的影响,并通过算例进行了说明。     

两级供应链契约协调研究

在批发价格契约的基础上,建立了供应链主体的决策模型,根据剩余产品在不同主体处残值的大小,合理选择产品的出清方式,从而达到供应链整体最优,发现只有当剩余产品在供应商处的残值大于在零售商处的残值时,供应链才能实现整体最优,从而达到供应链协调,并通过回购契约实现利润的分配。     

Coupons and price discrimination in vertically‐correlated markets

This research analyzes the non‐cooperative and cooperative strategies with respect to manufacturer and retailer coupons. In a model with one manufacturer selling its product to one retailer, it is found that the retailer can achieve third‐degree price discrimination equilibrium in retail markets by issuing coupons to demanders with higher elasticity. Although facing only one retailer, the manufacturer can also achieve the same third‐degree price discrimination equilibrium by issuing coupons directly to demanders of higher elasticity. However, when only one firm issues the coupon, both manufacturer and retailer coupons can help alleviate the channel profit loss due to double marginalization. If the manufacturer and the retailer non‐cooperatively issue coupons, then the subgame‐perfect Nash equilibrium outcomes are equivalent to those under the successive third‐degree price discrimination. Moreover, cooperative strategies between the manufacturer and the retailer can eliminate double marginalization, achieve the vertical integration effect, and lead to higher profits, consumer surpluses, and social surpluses than non‐cooperative coupon strategies.

A Comparison of Pay‐As‐Bid and Market‐Clearing Price Bidding Processes in Electric Utility Auctions

As the electric utility industry moves to Regional Transmission Organizations, there are more opportunities for merchant plants in selling wholesale energy to electric utilities. Two alternative bidding regimes are considered: (i) pay‐as‐bid and (ii) pay with market‐clearing bid. With stochastic price‐sensitive demand, we show that pay‐as‐bid has greater average price, but lower price variance than does market‐clearing price. Copyright © 2013 John Wiley & Sons, Ltd.     

Time-sensitive supply chain disruption recovery and resource sharing incentive strategy

Market demand is becoming increasingly time-sensitive in competitive environments. Hence, supply disruptions will have a more serious impact on the profits of supply chains. This study applies a Stackelberg competition between a single supplier and a single manufacturer in a time-sensitive supply chain in a cloud manufacturing environment. We aim to address the supplier’s production capacity recovery issues and the manufacturer’s incentive decision issues after supply disruption. We find that the supplier is in a weak position when the information is symmetrical. The manufacturer can encourage the supplier to shorten the recovery time by raising the unit wholesale price. When the supplier’s unit production cost remains unchanged but the unit wholesale price increases, the profit of the supplier first increases and then decreases. In addition, under the centralized decision-making setting, the optimal recovery time of the supplier is shorter and the optimal unit market price of the product is lower than that under decentralized decision-making. We further find that resource sharing can shorten the optimal recovery time, but it does not necessarily play an incentivizing role.     

基于外包的生产能力不足的供应链协调模型

文章以一个供应商与一个零售商组成的供应链为研究对象。其中,供应商生产产品的能力小于零售商的年需求量,此时供应商可以把自己缺失的这部分产品以一定价格外包给一个外部生产商,然后再把外包生产的产品重新供应给零售商,假设外部生产商允许原供应商货款延期支付一段时间。文章分别研究了在无外包与有外包协调两种情况下供应链的最优利润模型,并对协调前后利润进行了比较．结果表明外包可以提高供应链的利润,并且外包也是从供应链协调的观点解决供应能力不足的一个有效方法。同时还给出了根据延期支付时间来决策外包比例的条件。

Strategic inventory in capacitated supply chain procurement

We study the strategic role of inventory in a sequential two‐period procurement setting, where the supplier's capacity in the first period is limited and the retailer has the option to hold inventory. We compare the equilibrium under a dynamic contract, where the decisions are made at the beginning of each period, and a commitment contract, where the decisions for both periods are made at the beginning of the first period. We show that there is a critical capacity level below which the outcomes under both types of contracts are identical. When the first period capacity is above the critical level, the retailer holds inventory in equilibrium and the inventory is carried due to purely strategic reasons; as capacity increases, so does the strategic role of inventory. The supplier always prefers lower capacity than the retailer, and the difference between supplier‐optimal and supply‐chain optimal capacities, and the corresponding profits, can be significant. Finally, we find that the retailer's flexibility to hold inventory is not always good for the participants or for the channel. Copyright © 2008 John Wiley & Sons, Ltd.     

Supersize It: The Growth of Retail Chains and the Rise of the “Big‐Box” Store

This paper documents and explains the recent rise of “big‐box” general merchandisers. Data from the Census of Retail Trade for 1977–2007 show that general‐merchandise chains grew much faster than specialist retail chains, and that general merchandisers that added the most stores also made the biggest increases to their product offerings. We explain these facts with a stylized model in which a retailer’s scale economies interact with consumer gains from one‐stop shopping to generate a complementarity between a retailer’s scale and scope.     

The Coordination and Preference of Supply Chain Contracts Based on Time-Sensitivity Promotional Mechanism

To encourage retailers to submit orders as soon as possible, manufacturers usually launch a time-sensitivity promotional mechanism that the earlier you order, the cheaper the wholesale price will be in advance of the selling season. This paper aims to investigate if the mechanism can improve supply chain performance. A dyadic decentralized supply chain system comprising a single manufacturer and a single retailer is viewed as a research framework. Initially, a benchmark model is proposed to provide a criterion-referenced for coordinating the supply chain in a non-standard distribution environment. Second, a time-sensitive wholesale price contract is constructed to confirm that the mechanism can coordinate the supply chain. However, the retailer accepts the entire forecast risk under the contract. An improved contract called a time-sensitive revenue-sharing contract is constructed based on the notion that the manufacturer shares partial forecast risk. The results show that participants can arbitrarily divide the optimal supply chain’s expected profit between the constructed price contracts; however, two differences exist between the contracts, that is, participants have contract preferences. Finally, a numerical analysis and a few management insights are given.

Determinants of price mark‐up tolerance for green electricity – lessons for environmental marketing strategies from a study of residential electricity customers in Germany

This paper develops hypotheses on the effects of various attitudinal and perceptual variables as well as socio‐demographic characteristics of residential electricity customers on an individual's willingness to pay a mark‐up for electricity generated from renewable energy sources compared with the price due for electricity from conventional sources. The hypotheses are tested with data from a standardized telephone survey of 238 household electricity consumers in Germany. 53.4% of the participants are willing to pay a mark‐up for green electricity. 26.1% report a price tolerance equal to a 5–10% increase in their current electricity bill. Binary logistic and ordinal regression analyses indicate that price tolerance for green electricity is particularly influenced by attitudes (1) towards environmental issues and (2) towards one's current power supplier, (3) perceptions of the evaluation of green energy by an individual's social reference groups, (4) household size and (5) current electricity bill level. The findings are used to derive suggestions for energy related informational activities of public institutions, green marketing strategies of energy companies and future consumer research regarding demand for pro‐environmental goods.

考虑强势零售商压价和投资行为的供应链协调

中国流通产业的零供矛盾日益凸显,针对强势零售商的压价问题构建博弈模型并分析其对供应链协调的影响。在由单制造商和单零售商构成的二级供应链中,考虑零售商在主导产品零售价格的同时,通过增加广告投入或提高服务水平等市场投资措施刺激产品需求,探讨当零售商运用其较强的议价能力对制造商提出的批发价进行强制压价时,双方如何通过合作博弈寻找最佳策略。发现在一定的条件下,强势零售商的压价行为不仅可以提升品牌商誉,更能帮助实现供应链协调。     

基于价格有折扣的零售商订货问题

供应链运行环节中供应商与零售商的价格之争是一个长期讨论的问题,单纯从零售商节约成本的角度来定价较为简单,但现实中又存在"量大优惠"和"限额订购"的问题,这时定出的价格应是一个关于订货量的函数,从这个角度出发,零售商要重新权衡自己的订货量问题。
