Merger review with intermediate buyer power

Buyer power features prominently in antitrust cases and debates, particularly as it relates to the potential for a merger among suppliers to harm a buyer. Using a Myersonian mechanism design approach, Loertscher and Marx (2019b) provide a framework for merger review for markets with buyer power, assuming that buyer power is a zero-one variable. In the present paper, we extend this analysis by treating buyer power as a continuous variable (technically, as a Ramsey weight) that ranges from zero to one. This generalization is relevant because, among other reasons, the Ramsey weight can be interpreted as a conduct parameter that can be estimated. Moreover, we establish the robustness of prior results to an alternative way of modelling merger-related cost synergies, and we show that when an acquiring firm’s choice of target is endogenous, its profit-maximizing choice depends on the buyer’s power.     

The effect of social capital on local suppliers’ exploitative and exploratory learning in global buyer–supplier relationships: the moderating role of contract specificity

Drawing on the theories of social capital (SC) and organizational learning, a contingency theoretical framework that examines the impact of structural, relational, and cognitive SC on local suppliers’ exploitative and exploratory learning in the context of global buyer–supplier (GBS) relationships in China was developed. The extent to which the impact is moderated by the contract specificity between the buyer and supplier is also examined. The empirical results show significant positive impacts of structural and relational SC on local suppliers’ exploitative learning but significant negative impacts on local suppliers’ exploratory learning. More specifically, contract specificity strengthens the positive effects of all three dimensions of SC on exploitative and the negative effects of structural SC and relational SC on exploratory learning. They put forward several potential implications for practicing managers and policymakers.     

The Chinese paradigm of global supplier relationships: Social control,formal interactions and the mediating role of culture

This paper reports the results of a study that examined how firms can establish successful business relationships with Chinese suppliers. Its aim is to explore salient characteristics of the nature of buyer supplier relationships with the emergence of China as a dominant economic power. Two surveys have been conducted that investigated several factors that inhibit and enable effective supplier relationship management (SRM) between organisations sourcing from China and Chinese suppliers, and explored the impact of cultural characteristics of Chinese management on the nature and performance of supplier relationships. The research highlights the importance of the social control aspect of governance structure of supplier relationships and stresses that both social and formal control mechanisms should be implemented for more effective relationships with Chinese suppliers. It also demonstrates the need for companies to recognise the importance of guanxi and several cultural characteristics of the Chinese style of management in SRM and advocates the need for the development of a hybrid Sino-Japanese and global supplier relationship management paradigm that incorporates elements from the existing SRM models. It generates insights into how the cultural context of emerging markets affects the nature of business relationships and generates a research agenda in the field of supply chain management that can explore the development of new paradigms in supplier relationships management. The main theoretical argument put forward centres on the need for the development of a new global supplier relationship management paradigm that will take into account the cultural elements of the Chinese society.     

Managing interdependencies in supplier networks

Building and managing a supplier base has been referred to in the literature as a key aspect of supplier management. Scholars have proposed a number of models aimed at enhancing the effectiveness of supplier network management, mainly based on a portfolio approach. In the IMP tradition of research, those models are often criticized as they ignore the interdependencies between the different existing dyadic relationships of a focal buyer company and its suppliers. Such interdependencies are the main focus of this paper, which has four objectives: (1) To analyze the types of relationships linking suppliers, (2) to understand the factors and dynamics underlying the creation and management of these relationships (3) to uncover existing links between buyer-supplier and supplier-supplier relationships, and (4) to clarify how different configurations of supplier relationship interactions impact on the performance of the actors involved. The paper discusses two empirical case studies, using the supplier networks of two focal buyer companies. We find that supplier interdependencies are mainly a by-product of the buyer-supplier dyads. Furthermore, the nature and dynamics of these dyads are a strong determinant of the scope and frequency of supplier connections and the corresponding effects on performance.     

Key supplier relationships and product introduction success: The moderating roles of self-enforcement and interdependence between buyer and supplier

This study investigates the extent to which strong relationships between a firm and its key suppliers promote effective new product introduction. Building on the relationship marketing literature, we identify self-enforcement and interdependence as two contingent relational variables that influence the strength of the buyer–supplier relationship. We use data from a survey of 2331 manufacturing firms in China to test the hypotheses. The results show that strong relationships with key suppliers correlate with product introduction success and that this positive effect is contingent on the two relational variables identified. Self-enforcement strengthens the utility of strong supplier relationships for these Chinese manufacturers, and buyer–supplier interdependence enhances this relationship.     

“I want you back”: On the strategic roles of boundary spanners in supplier switching-back processes

This paper builds upon literature addressing boundary spanners and switching suppliers in order to explore an under-examined aspect of buyer–supplier relationships: how different individuals at multiple organisational levels affect processes by which firms return, or “switch back”, to former suppliers after breaches in their relationships. Our study followed a qualitative approach by applying an abductive research methodology to make sense of 85 semi-structured interviews with executives involved in the erstwhile buyer–supplier relationships that we investigated. We found that supplier switching-back processes (SSBPs) can be understood as constituted by a set of alignments and misalignments between boundary spanners (i.e. top management, purchasing and sales agents, engineers and technicians) in the organisations involved. Thus, peoples' interactions, or lack thereof, directly affect the possibility for buyers and suppliers to restore their severed relationships. We conclude that boundary spanners pursue seven distinct roles during different periods in SSBPs, roles that relate to three identified functions of boundary spanners in such processes. The paper closes by highlighting what our findings imply for business managers, limitations and some possible directions for future research.     

The impact of customer attractiveness and supplier satisfaction on becoming a preferred customer

This paper discusses how a firm can become preferred customer, defined as a particular buying firm to whom the supplier allocates better resources than less preferred buyers. Two concepts play a central role for a firm aiming to become preferred customer: (i) customer attractiveness and (ii) supplier satisfaction. However, the current literature still lacks a clear discussion on the conceptual differences between these constructs and their attributes and is ambiguous with regard to the relationships between the concepts. This study addresses these shortcomings. We examine customer attractiveness and supplier satisfaction as distinct conceptual variables and test how these constructs relate to each other and to preferred customer status. We build upon practitioner input and survey data from 91 suppliers to do so. Our analyses show that the impact of customer attractiveness on preferential resource allocation from suppliers is significantly mediated by supplier satisfaction. These findings expand the current understanding of these concepts. In addition, our findings might help managers better evaluate their relationships with suppliers and align their strategies accordingly to obtain better resources from their suppliers.     

Why Do Suppliers Charge Larger Buyers Lower Prices?

The phenomenon of input suppliers charging larger buyer firms, relative to smaller buyer firms, lower prices is commonly explained in terms of supplier economies of scale, supplier competition for larger buyers, and the larger bargaining power of larger buyers. This paper provides an alternative explanation, and shows that the observed direction of differential pricing can benefit the supplier by lowering the level of tacit collusion its buyers can sustain in their output market. This result also provides a new mechanism through which a ban on price discrimination by input suppliers may lower consumer welfare.     

The impact of OEM supplier initiatives on buyer competence development: The moderating roles of collaborative relationship and competitive environment

This paper explains the impact of original equipment manufacturing (OEM) supplier initiatives, which are proactive and deliberate behaviors, on buyer competence development. It argues that these adaptive and proactive behaviors in the outsourcing relationship have a significant impact on buyers’ competence development. The sample population consisted of 800 OEM suppliers in Taiwan. SPSS was used to examine the causal relationships among the variables. The empirical results indicate that OEM supplier initiatives have a positive effect on buyer competence development. In addition, two of three collaborative relationship variables—information sharing and long-term collaboration—foster the relationship between OEM supplier initiatives and buyer competence development. However, the moderating role of competitive environment has a negative effect on this relationship.     

Intermediaries in power-laden retail supply chains: An opportunity to improve buyer–supplier relationships and collaboration

Despite the benefits of buyer and seller collaboration and hence relationships extolled in extensive studies, issues of relationship power inhibit implementation of collaborative and relational approaches, particularly in some parts of the retail sector. Further, most research regards buyer–supplier collaboration and relations as dyadic or focal relationships, or perhaps in a network context, and typically investigates buyer–supplier collaboration and relations from a power-dependency perspective; and within vertical supply integration. Little attention has been given to the potential role of supply chain intermediaries, such as logistics service providers, in objectively and independently determining and managing the course of buyer–supplier collaboration and relations in a business-to-business context. This article appraises the potential role of buyer–supplier collaboration and relations and their relevant opportunities in the power-laden, contentious environment of the retail grocery sector. With an interdisciplinary approach, drawn from supply management, relationship management, and logistics and supply chain management, this article emphasises the importance of horizontal collaboration using fourth-party logistics structures as horizontal intermediary conduits, who act independently between retailers and suppliers to facilitate collaborative and relational activity.     

Buyer and supplier attractiveness in a strategic relationship — A dyadic multiple-case study

In a strategic buyer–supplier relationship (BSR), both the buyer and the supplier aim to leverage the relationship for gaining competitive advantage. Since strategic BSR requires a lot of effort from both parties, firms have become very selective in terms of with whom they engage in a strategic BSR. Therefore, both buyers and suppliers must shape their attractiveness in order to get the other party to put effort to the relationship. Towards this end, the present study explores the drivers of buyer and supplier attractiveness in strategic relationship through 43 interviews in six buyer–supplier dyads. We identified four main categories of both buyer and supplier attractiveness: 1) economic-based, 2) behavior-based, 3) resource-based, and 4) bridging-based attractiveness. We find economic- and behavior-based attractiveness strongly present in all dyads, while resource- and bridging-based attractiveness are emphasized when the strategic intent has more explorative elements and when the aim is to leverage the dyadic relationship in developing businesses outside the dyad. We synthesize our results to a model of attractiveness in a strategic BSR, which bring forth dyad considerations of buyer and supplier attraction.     

Risky Business or Competitive Power? Supplier Involvement in Japanese Product Design

Notwithstanding the alleged risks of outsourcing design work, leading manufacturers in the Japanese automotive industry collaborate closely with their key suppliers. Despite widespread recognition of the effectiveness of these close-knit supplier networks, however, little research exists on the factors that affect the purchase of design work from suppliers. S. Nazli Wasti and Jeffrey K. Liker fill this gap by exploring the factors that affect Japanese automotive firms' purchase of design work from their component suppliers. Using data from a survey of 122 Japanese automotive component suppliers, their study addresses two key questions. First, what factors lead Japanese buyers to involve some suppliers heavily in design while giving others relatively little control over design decisions? And second, does the Japanese practice of involving suppliers in design offer performance benefits? The study focuses on first-tier suppliers of parts, assemblies, and complete subsystems (e.g., audio, fuel and emissions, heating and air conditioning). The study does not include suppliers of raw materials and chemicals, assembly and processing equipment, indirect materials, tooling and dies, computers and software, or engineering and business consulting services. The study breaks down the broad concept of supplier involvement in design work into three measurable elements: the extent to which the supplier influences decision-making during the early stages of product development; the amount of control the buyer retains over the design; and the frequency of design-related communication between the buyer and the supplier. Factors that have a positive effect on the level of supplier involvement among the companies studied include technological uncertainty of the component and the supplier's in-house technical capabilities. For companies in the study, the level of competition in the supplier market has a negative effect on the degree of supplier involvement in design. The responses indicate that supplier involvement offers performance benefits for both the supplier and the buyer. For the supplier firms studied, increased involvement in the design process permits greater focus on design for manufacturability (DFM). And of course, supplier-generated design improvements clearly benefit the buyers, allowing these firms to capitalize on the experience and the insight that their suppliers have regarding the parts that they supply.     

The multiple levels of trust when selecting suppliers – Insights from an automobile manufacturer

In this study, we aim to develop a framework for the concept of trust prior to forming relationships when selecting suppliers. Entering a relationship with a supplier for an extended period requires a certain level of trust in different facets (such as interpersonal relationships, continuous supply, and compatibilities). In situations in which suppliers need to enter into relationships characterized by high uncertainties, such as sourcing for high technology, trust becomes even more important. The question raised is how this ex-ante trust is defined and used during the supplier selection, when the buyer decides to enter into a relationship with a potential supplier. The phenomenon is studied in the automobile industry, which is experiencing a higher level of dependency on suppliers for sensitive, and at times strategic, components. A single case of a major auto manufacturer is studied using 36 interviews. Our findings show that when selecting the supplier with which to enter a relationship, trust manifests itself on multiple levels: interpersonal, organizational, interorganizational, and network. Contrary to some previous suggestions in the literature, we found interrelationships across these levels.     

Decomposing the effect of supplier development on relationship benefits: The role of relational capital

Buyers invest considerably in developing their suppliers, yet the performance effects of such investments are not universal. Drawing on social capital theory, this research investigates whether the relationship between supplier development and relationship benefits may be facilitated by the generation of relational capital. The authors examine mediating and moderating roles of relational capital in the relationship between two aspects of supplier development (capability development, supplier governance) and two dimensions of relationship benefits (supplier benefits, buyer benefits), using survey data collected from 185 suppliers of a large manufacturing firm. Investment in supplier development does not automatically result in benefits for the supplier or reciprocated benefits for the buyer. Rather, relational capital “bridges” supplier development and relationship benefits. Without relational capital, benefits from capability development do not accrue, and the impact of a supplier governance regime can be even detrimental. In conditions of high relational capital, capability development results in lower perceived buyer benefits. The results can help managers ensure that the benefits from their supplier development efforts fully materialize.     

Value for value—The dynamics of supplier value in collaborative new product development

Suppliers are recognized as an important source of innovation. Research into supplier involvement in new product development has shown that benefits can potentially be reaped by customers. However, a relatively unexplored precondition is the willingness of suppliers to invest in their customers’ innovative efforts. In this exploratory, theory-extending research, we investigate the value that a supplier can experience from being involved in high tech firms’ new product development. We find that value comes in three forms for suppliers: (1) financial payment for sales volumes and product development services, (2) technological knowledge and product designs, and the (3) reputation of doing business with leading-edge firms Additionally, we place this in a dynamic, long-term perspective, and find indications for a positive or negative feedback effect, depending on the emphasis the buyer puts on collaborative innovation with the supplier and the extent to which suppliers can use competences, knowledge and reputation resulting from the collaboration in subsequent business development activities. The positive effect results in added value for both parties in the dyad, and the negative effect leads to the opposite.     

Buyer attractiveness as a catalyst for buyer–supplier relationshipdevelopment

The concept of buyer attractiveness has received increasing scholarly attention in the recent business marketing literature, yet empirical studies of the dynamics between buyer and supplier attractiveness and their implications for relationship development are scarce. The research framework presented in this study suggests that buyer attractiveness is connected, first, to supplier's experienced and expected business outcomes within the focal relationship, and second, to the leverage impact of the focal relationship on supplier's other relationships. A qualitative case study of two buyers and their key suppliers scrutinizes the dimensions of attractiveness associated with relationship development. The findings indicate that attractiveness and adaptations performed by the buyer and the supplier are interlinked in a mutually reinforcing or deteriorating manner, forming a mechanism that catalyzes relationship development. These findings and the resultant empirically grounded framework provide a conceptualization and enhanced understanding of the dynamics between attractiveness, adaptations and relationship development.     

Buyer Market Power and Innovative Activities

This empirical paper deals with the effects of supplier and buyer market concentration on the innovative behavior of suppliers within the German automobile industry. The data set contains firms from all size classes and covers measures of innovation input as well as innovation output. It can be shown that (a) firms' innovation and R & D-employment intensity will decline (increase) in buyer concentrations if supplier markets are low (high) concentrated; (b) buyers' pressure on input prices reduces suppliers' innovation expenditures and their incentive to develop new products; (c) a small number of competitors in suppliers markets and a large stock of customers stimulates innovative behavior; (d) small and medium sized suppliers invest more in their innovative activities but have less probability of realizing innovations than larger firms; and (e) higher technological capabilities lead to higher innovation input and output.     

Gaining from vertical partnerships: knowledge transfer,relationship duration,and supplier performance improvement in the U.S. and Japanese automotive industries

We study sources of operational performance improvement in supplier partnerships. We argue that supplier performance will benefit most where time‐bound relational assets have developed between a buyer and supplier and the firms exploit the resulting communication efficiency by transferring productive knowledge. We examine the effects of two forms of knowledge exchange together with the prior duration of the buyer–supplier relationship. We find similar interaction patterns in two survey samples of Japanese and U.S. automotive suppliers. The effect of ordinary technical exchanges on supplier performance improvement does not vary with relationship duration. The effect of higher‐level technology transfer, however, grows more positive as relationship duration increases. Other results show relevant contrasts consistent with heterogeneous sourcing behavior between the two countries. The findings highlight the role of relational assets and show that it is important to distinguish between simple techniques and higher‐level technological capabilities when studying interfirm relationships. This research extends the literatures on knowledge transfer, buyer–supplier partnerships, and the performance dynamics of interfirm and intrafirm relationships in general.

Cartelization Through Buyer Groups

Retailers may enjoy stable cartel rents in their output market through the formation of a buyer group in their input market. A buyer group allows retailers to commit credibly to increased input prices, which serve to reduce combined final output to the monopoly level; increased input costs are then refunded from suppliers to retailers through slotting allowances or rebates. The stability of such an ‘implied cartel’ depends on the retailers’ incentives to source their inputs secretly from a supplier outside of the buyer group arrangement at lower input prices. Cheating is limited if retailers sign exclusive dealing or minimum purchase provisions. We discuss the relevancy of our findings for antitrust policy.     

Corrigendum to “The effect of spatial variables on the economic and environmental performance of bioenergy production chains” [Int. J. Prod. Econ. 131 (2011) 224-233]

Using a knowledge-based perspective, we identify and test the conditions enabling inter-firm learning in the aerospace supply chain. We focus on buyers accessing knowledge from their suppliers. Hypotheses are tested via a cross-sectional survey of supplier relationships of prime contractors in Canada's aerospace industry. The variables identified as having a significant impact on inter-firm learning are as follows: the quality of the buyer–supplier relationship in terms of trust, collaboration, socialization and information sharing; the proprietary links between both firms; and the use of ITC collaboration tools.
