The Role of Contract Negotiation and Industry Structure in Production Outsourcing

Despite the spread of cost‐driven outsourcing practices, academic research cautions that suppliers' cost advantage may weaken manufacturers' bargaining positions in negotiating outsourcing agreements, thereby hurting their profitability. In this study, we attempt to further understand the strategic impact of low‐cost outsourcing on manufacturers' profitability by investigating the contractual form of outsourcing agreements and the industry structure of the upstream supply market. We consider a two‐tier supply chain system, consisting of two competing manufacturers, who have the option to produce in‐house or to outsource to an upstream supplier with lower cost. To reach an outsourcing agreement, each manufacturer engages in bilateral negotiation with her supplier, who may be an exclusive supplier or a common supplier serving both manufacturers. Our analysis shows that wholesale‐price contracts always mitigate the competition between manufacturers regardless of whether they compete with price or quantity. In contrast, two‐part tariffs intensify the competition when the manufacturers compete with quantity, but soften it when they compete with price. As a result, when outsourcing with two‐part tariffs, the manufacturers may earn lower profits than they would from in‐house production, although the suppliers are more cost efficient. This suggests that managers have to be wary about the downside of using coordinating contracts such as two‐part tariffs when pursuing low‐cost outsourcing strategies. Our analysis also sheds some light on the profitability of using an exclusive supplier for outsourcing. When outsourcing with wholesale‐price contracts, the competing manufacturers are better off outsourcing to an exclusive supplier. However, when outsourcing with two‐part tariffs, the manufacturers may earn higher profits by outsourcing to a common supplier than to an exclusive one when the manufacturers' bargaining power is sufficiently strong (weak) under quantity (price) competition.     

多部件采购外包的两阶段均衡投标策略

本文考虑一个由单个制造商和多个供应商群体组成的供应链——该制造商需要采购多个部件,对于每个部件在市场上均存在多个供应商。不同于传统的从各供应商群体分别采购各个部件,制造商考虑将所有部件的采购整体外包给某个供应商。在第一阶段,制造商使用一级价格密封投标的逆向拍卖来确定赢得整体采购合约的供应商。接下来,第一阶段投标的获胜者生产其所能供应的部件,并使用逆向拍卖向第一阶段中未获胜的其他竞标者采购其余部件。我们分析了供应商在两个阶段的均衡竞价策略,并比较了制造商在亲自逐件采购和外包整体采购两种情况下的期望采购成本。我们证明了在两种机制下制造商的总的期望采购成本相等。     

供应链中具有产能限制的竞争企业中的信息共享研究

本文研究由一个供货商和两个制造商组成的二级供应链中，制造商之间的横向信息共享策略和供应商的定价问题。在模型中，上游供应商同时为下游两家制造商提供价格相同的原材料，下游制造商生产具有替代性的商品进行数量竞争，并受到相同的产能限制。以Cournot博弈为研究手段，求解了制造商的均衡订货决策和信息共享策略，分析比较了在不同的信息共享策略下制造商的利润、供应商的利润和批发价格。本文在研究制造商的信息共享策略时考虑了上游供应商的批发价格的影响。研究表明，当均衡解受到产能约束时，制造商的信息共享策略会反向。在某些情况下，完全信息共享和完全信息不共享都可能成为博弈的占优策略。上游供应商通过调整批发价格可以影响制造商的信息共享决策。该模型为上游供应商提供了一种最优定价策略，也为下游制造商提供了求解自身最优订货量和信息共享决策的方法。     

Sourcing Decisions with Competitive Suppliers and Imperfect Information

Manufacturers often must choose between outsourcing and producing internally. This choice is complex and influenced by a variety of factors, including the costs and capabilities of the potential suppliers. In addition, if the manufacturer outsources, he must design the sourcing process. We study the manufacturer's outsourcing decision, with a focus on the impact of the sourcing process on that decision. We consider a setting in which the manufacturer has imperfect information regarding the suppliers' costs and capabilities, and we assume that the manufacturer uses a two‐stage sourcing process. The first stage is the qualification stage, in which the manufacturer seeks to reduce the uncertainty regarding the suppliers' capabilities. The second stage is the supplier selection stage, in which the manufacturer selects among the qualified suppliers on the basis of price. We first characterize the optimal design of the two‐stage process, and then consider the outsourcing decision. We demonstrate several trade‐offs. Vertical integration enables the manufacturer to reduce uncertainty and extract all of the profits of production. However, outsourcing enables the manufacturer to take advantage of the (potentially) lower costs and higher capabilities of the suppliers, particularly if competition between suppliers can be encouraged. We find that the manufacturer is more likely to vertically integrate when the warranty cost and the cost of exerting effort during qualification are large, and when there is significant uncertainty regarding the suppliers' capabilities. The manufacturer is more likely to outsource when the suppliers' costs (capabilities) are low (high), and when the number of suppliers is large.     

Pricing and ordering decisions in a supply chain with downward substitution and imperfect process yield

We consider a manufacturer sourcing from two suppliers of asymmetric component quality and producing a quality-differentiated product, namely a low- and high-quality version, with each having deterministic demand. The manufacturer adopts the existing process to produce low-quality products with components from the supplier with low component quality, and develops a new process to produce high-quality products with components from the supplier with high component quality. The new process has imperfect yield, and products that do not meet the specifications for high-quality products can substitute for low-quality products produced with the existing process. We investigate the suppliers’ price decisions and the manufacturer’s ordering and production decisions in a game-theoretical model under dual sourcing. Our analyses reveal that increasing product differentiation or higher yield of high-quality products do not necessarily translate to a higher profit for the manufacturer. In light of the manufacturer’s sourcing strategies, we show that sourcing from a single supplier with high- and low-quality components yields a lower profit than sourcing from one supplier with high component quality and the other with low component quality. Finally, we investigate the manufacturer’s decision-making with endogenous yield rate of high-quality products. Our analyses demonstrate that the manufacturer benefits from setting the yield rate of high-quality products ahead of the suppliers’ price decisions.     

Outsourcing Decisions and Managerial Incentives*

An agency model is presented in which outsourcing strictly dominates in-house production. We argue that firms outsource in order to improve managerial incentives. Conditions are established under which the firm is strictly better off with outsourcing. The benefit of outsourcing, however, is constrained by the trade-off between the incremental coordination costs of outsourcing and the improved incentive structure. The optimal contract is also shown to be a function of whether or not the firm is publicly held. For a publicly held firm, the contract is constant. For a privately held supplier, the contract is likely to be of a cost-sharing type. These findings offer preliminary incentive explanations for commonly observed outsourcing practices.     

考虑供应商产品交付水平的供应链融资策略研究

供应商产品的交付水平直接影响下游制造商的生产，但是这种现象没有得到供应链金融研究的重视。为此，本文将供应商交付水平和供应链的运营融资问题结合起来研究。在考虑供应商产品交付水平的情况下，通过研究资金不足的供应商分别利用制造商预付款融资和风险投资方股权融资时，供应商的最优运营决策和融资策略，最后考虑了供应商对两种融资方式的选择。研究结果表明，供应商的自有资金水平对供应链均衡决策及其收益影响很大，有限的自有资金严重制约了供应商产品的交付水平，降低了供应链的运作效率；不管是资金充足，还是选择融资，供应商的利润不仅与自身的运营效率有关系，而且与替代供应商产品的批发价格有很大关系，当供应商的运营效率较低时，供应商的利润随着替代供应商产品的批发价格先增大后减小，当供应商运营效率较高时，供应商的利润随着替代供应商产品的批发价格逐渐增大。当供应商进行融资时，若自有资金水平较低，应通过股权融资的方式进行融资，若自有资金水平较高，供应商应该选择制造商预付款的方式进行融资，若自有资金量超过预付款融资时供应商所需资金的阈值时，供应商选择不融资。     

Managing Supplier Competition and Sourcing Sequence for Component Manufacturing

We consider a setting in which a manufacturer sequentially sources two components and uses reverse auction to select a supplier with the lowest bidding price for each component. The manufacturer chooses a quantity to order from each supplier and a price for selling the final product. We show that the interplay between the direct competition faced by suppliers in providing their respective components and the sequence whereby the manufacturer sources components influence system performance in a subtle, and sometimes dramatic, way. As the direct competition for the early sourced component intensifies, the profit of its supplier will deteriorate while the profits of the other firms will improve. As the direct competition for the late sourced component intensifies, however, the profit of its supplier may improve, and the profits of the other supplier, the manufacturer, and the system can all decrease. Compared with when the manufacturer simultaneously sources the components, sequentially sourcing the components can benefit the manufacturer and every supplier. Furthermore, all the channel parties can unanimously agree on a specific sourcing sequence. All of these signify the importance for manufacturers to take appropriate measures to manage their sourcing procedures and the competition environments faced by their suppliers.     

Supplier quality assessment to identify depth technical knowledge of component reliability

As a result of global competition, international companies that manufacture photocopiers, printers or car navigation systems have to purchase low-cost electronic components such as semiconductors and hard disk drives by outsourcing production. However, it is often difficult for these companies to evaluate the quality of their suppliers through interviews and technical documentations. This article proposes new measures for supplier assessment and a systematic approach to select suppliers that have in-depth knowledge of component reliability and technology. The measures for selection not only include the physical quality of components but also information disclosures provided by suppliers, which consist of failure analysis, reliability data and details of the design-manufacturing process. The proposed measures are applied to real data of photocopier manufacturing enterprises. Experiments conducted show that a systematic assessment will enable selecting appropriate suppliers with a lower failure rate.     

The Impact of Contracts and Competition on Upstream Innovation in a Supply Chain

We consider a supply chain with an upstream supplier who invests in innovation and a downstream manufacturer who sells to consumers. We study the impact of supply chain contracts with endogenous upstream innovation, focusing on three different contract scenarios: (i) a wholesale price contract, (ii) a quality‐dependent wholesale price contract, and (iii) a revenue‐sharing contract. We confirm that the revenue‐sharing contract can coordinate supply chain decisions including the innovation investment, whereas the other two contracts may result in underinvestment in innovation. However, the downstream manufacturer does not always prefer the revenue‐sharing contract; the manufacturer's profit can be higher with a quality‐dependent wholesale price contract than with a revenue‐sharing contract, specifically when the upstream supplier's innovation cost is low. We then extend our model to incorporate upstream competition between suppliers. By inviting upstream competition, with the wholesale price contract, the manufacturer can increase his profit substantially. Furthermore, under upstream competition, the revenue‐sharing contract coordinates the supply chain, and results in an optimal contract form for the manufacturer when suppliers are symmetric. We also analyze the case of complementary components suppliers, and show that most of our results are robust.     

食品供应链中质量投入的演化博弈分析

针对频频出现的食品安全事件,以及食品供应链质量投入的外部正效应问题,建立了供应商与制造商食品质量投入的演化博弈模型,并进行求解分析。结果表明:食品供应商与制造商的质量投入策略与双方质量投入产出比密切相关,当双方质量投入产出比不断变化时,出现多种演化稳定均衡。如果"搭便车"行为从对方质量投入中获得的收益很大,则供应商或者制造商进行质量投入的积极性会大大降低。政府进行调控,对于"搭便车"行为进行惩罚,迫使供应商或制造商进行质量投入,对于质量投入产出比较小的供应商或制造商给予补贴,激励他们进行质量投入,增大食品的安全性。     

Outsourcing Competition and Information Sharing with Asymmetrically Informed Suppliers

This paper studies an outsourcing problem where two service providers (suppliers) compete for the service contract from a client. The suppliers face uncertain cost for providing the service because they do not have perfect information about the client's type. The suppliers receive differential private signals about the client type and thus compete under asymmetric information. We first characterize the equilibrium of the supplier competition. Then we investigate two of the client's information sharing decisions. It is shown that less information asymmetry between the suppliers may dampen their competition. Therefore, the client does not necessarily have the incentive to reduce information asymmetry between the suppliers. We characterize the conditions under which leveling the informational ground is beneficial to the client. We also find that under the presence of information asymmetry (e.g., when the suppliers have different learning abilities), sharing more information with both suppliers may enhance the advantage of one supplier over the other and at the same time increase the upper bound of the suppliers' quotes in equilibrium. Consequently, the suppliers compete less aggressively and the client's payoff decreases in the amount of shared information. The findings from this study provide useful managerial implications on information management for outsourcing firms.     

The Influence of Cost and Quality Priorities on the Propensity to Outsource Production*

Outsourcing of production has escalated over the past decade due to unprecedented competition and worldwide access to low‐cost labor markets. This article examines how cost and quality priorities—two key attributes of manufacturing strategy—influence a manufacturer's propensity to outsource. By doing so, we bridge the existing gap between research on manufacturing strategy and firm boundaries. We develop a theory‐based model that links a manufacturer's cost and quality priorities to its plans to outsource production. Our empirical analyses, based on survey data obtained from 867 manufacturing business units, control for firm‐specific factors previously shown to impact outsourcing, including asset specificity, uncertainty, and current capabilities in cost and quality. We found that the competitive priority placed on cost played an integral role in sourcing decisions, while, surprisingly, conformance quality priorities did not. The cost result is consistent with our expectations and observations in practice. The significant effect of cost priority on outsourcing shows that any theory of firm boundaries that fails to consider competitive priorities is incomplete. The finding regarding quality, which was counter to our expectations, may partially explain why there is an emergence of so many nonconforming products associated with outsourcing. Taken together, our results provide theoretical insights for future research into how manufacturing managers can improve their decision making on outsourcing production.     

The effect of supplier development on outsourcing performance: the mediating roles of opportunism and flexibility

Abstract

In this increasingly competitive business environment, firms utilise outsourcing as a strategic tool to leverage globally dispersed resources so that they may focus on their core competencies and improve efficiency. The more firms rely on outsourcing, the more they depend on their suppliers, and the more important it is to manage and develop suppliers in order to achieve and maximise the benefits of outsourcing. This paper explores the impact of supplier development on outsourcing performance. Structural equation modelling was used to analyse data collected from 213 manufacturing firms in China. The results indicate that supplier development has a strong direct positive impact on outsourcing performance, and that supplier development also leads to enhanced outsourcing performance through reducing outsourcing opportunism risk and improving outsourcing flexibility. In addition to making a contribution to current theories of outsourcing, our findings also provide outsourcing managers with practical understanding and insights about the role of supplier development in enhancing outsourcing performance.     

Fit between sourcing capabilities and organisational structure on IT outsourcing performance

Thus far, relatively few studies on the supplier side of Information Technology (IT) outsourcing arrangements have been based on empirical quantitative research. Previous research identified a recurring supplier problem, a lack of sustainability in IT performance. The literature revealed that a supplier's capabilities and organisational structure affect the supplier performance. We hypothesise that realising a fit between the necessary sourcing capabilities and organisational structure on the IT supplier side will result in a sustainable sourcing performance. We executed a survey research among employees involved in sourcing activities of three different IT outsourcing suppliers (N?=?135). The results from our analysis provide evidence that these constructs can be used to analyse differences between the three types of service suppliers. Results indicate that suppliers who focus on establishing a fit are more willing or able to monitor if they achieve a sustainable performance.     

Delegation vs. Control in Supply Chain Procurement under Competition

This paper studies the optimal component procurement strategies of two competing OEMs selling substitutable products. The OEMs outsource their production to a common contract manufacturer, who in turn needs an input from a component supplier. Each OEM may either directly procure the input from the component supplier, or delegate the procurement task to the contract manufacturer. We first analyze the OEMs' procurement game under a non‐strategic supplier whose component price is exogenously given. It is found that symmetric equilibria arise for most situations, that is, both OEMs either control or delegate their component procurement in equilibrium. Interestingly, despite the commonly‐held belief that the contract manufacturer would be worse off as OEMs gain component procurement control, we show that the contract manufacturer may enjoy a higher profit. Then we study the OEMs' procurement game under a strategic supplier who can set its component price. We find that the supplier's strategic pricing behavior plays a critical role in the equilibrium procurement structure. In particular, in the equilibrium under strategic supplier, the larger OEM always uses delegation while the smaller OEM may use either delegation or control. By identifying the driving forces behind the OEMs' procurement choices, this research helps explain observed industry practices and offer useful guidelines for firms' component sourcing decisions.     

A Structural Analysis of the Effectiveness of Buying Firms' Strategies to Improve Supplier Performance

Many manufacturing firms have increased the amount of component parts and services they outsource, while refocusing on their core capabilities. Outsourcing parts and services to independent, external suppliers means that suppliers' performance is increasingly critical to the long‐term success of these buying firms. Buying firms are increasingly using disparate supplier development strategies to improve supplier performance including supplier assessment, providing incentives for improved performance, instigating competition among suppliers, and direct involvement of the buying firm's personnel with suppliers through activities such as training of suppliers' personnel. Using resource‐based theory, internalization theory, and structural equation modeling, we examine the impact of these supplier development strategies on performance. We conclude that direct involvement activities, where the buying firm internalizes a significant amount of the supplier development effort, play a critical role in performance improvement.     

Supply chain configuration conundrum: how does the pharmaceutical industry mitigate disturbance factors?

How a supply chain (SC) is configured can have a significant impact on the performance of global firms. More specifically, disturbance factors (i.e. those factors associated with uncertainty and risk) are increasingly important considerations. This paper focuses on endogenous, exogenous and environment-related SC disturbance factors and their relative importance when configuring global SCs. Three alternative scenarios of SC configurations for European-based pharmaceutical firms are identified – insource nearshore, outsource nearshore and outsource offshore. Through a multi-phase, mixed-methods approach we find that the top five disturbance factors managers should be aware of while configuring their SCs are quality defects, unforeseen and random interruptions in manufacturing processes, order processing difficulties, untimely delivery of products and a mismatch between market demand and supplier responsiveness. This study is able to provide insights into the impact of disturbance factors on the SC configuration strategy for Big Pharmas (BPs). We show that SC disturbances influenced the decision to bring production back home (reshoring) or to a closer location (nearshoring). To mitigate the effects of disturbances many BPs recalibrated their SC configurations by insourcing core products, outsourcing non-core products offshore and developing offshore insourcing capabilities through ‘captives’.

Vertical Integration under Competition: Forward,Backward, or No Integration?

We consider two competing supply chains, each consisting of supplier, a manufacturer, and a retailer. The suppliers exert effort to improve product quality, and the retailers sell products competitively. Each manufacturer chooses one of the three strategies: forward integration, backward integration, or no vertical integration. We seek for a subgame perfect Nash equilibrium and study the resulting market structure. Moreover, we characterize the effect of vertical integration on profitability, product price, and quality in a competitive setting. Existing literature has shown that, when manufacturers consider only forward integration, they may choose not to vertically integrate in equilibrium. In contrast, we find that, when both forward and backward integration options are considered, disintegration cannot be an equilibrium outcome. In this case, both manufacturers either forward or backward integrate, and the degree of product perishability, cost of quality, and how much consumers value quality are critical for the chosen direction of integration. Furthermore, competition increases attractiveness of backward integration relative to forward integration. We show that, while integrating backward unilaterally is always beneficial, unilateral forward integration can harm a manufacturer's profitability. Finally, vertical integration can result in a better quality product sold at a lower price.
