Toward Assessing Supplier Value

Abstract

This research investigates criteria currently used in the evaluation of suppliers, the importance of those criteria in the selection and the retention process as well as their potential in adding value. Results suggest significant differences in all areas. Most importantly, this research identifies key criteria considered important for adding value to a buying partner. Study results may be used by suppliers in developing their channel partner offerings and by buyers in evaluating suppliers for selection and retention purposes.     

Understanding the causes of defection among satisfied B2B service customers

Abstract

Many research studies conclude that satisfaction is strongly and positively related to repurchase intentions and loyalty behaviour. However, companies are often faced with the perplexing question of why some customers, who are satisfied, still switch suppliers given the right circumstances. To answer this question, an exploratory research study was conducted in the facilities-management industry with business-to-business service customers. The study was conducted in two stages: an exploratory stage that focused on the industry as a whole, and a confirmatory stage that focused on lost customers from one specific company. It was found that switching motives and actual reasons for switching are quite different. Customers, despite being satisfied, are more likely to switch suppliers for price reasons than they originally stated.     

Information Asymmetries as Antecedents of Opportunism in Buyer-Supplier Relationships: Testing Principal-Agent Theory

ABSTRACT

Purpose: A severe problem in supplier selection refers to moral hazard: suppliers not behaving in the expected way once contracted. Principal-agent theory could provide insights on how to reduce this problem. Because buyer–supplier relationships can be interpreted as principal-agent situations, the application of agency theory should facilitate improved supplier selection. Although theoretically compelling, empirical tests verifying this assumption are not prevalent. Regarding the advancement of theory, this paper tests whether both ex ante and ex post information asymmetries influence moral hazard. In particular, in the context of a globalizing economy with a subsequent increase in information asymmetries as a problem in supplier selection, this conceptual approach may be contributive.

Design/methodology/approach: The authors use a set of 87 buyer–supplier relationships to conduct a test, applying a partial least squares model with latent variables. A particularity of the data set is that it contains information on ongoing as well as on discontinued relationships.

Findings: The analysis indicated that both ex ante information asymmetries (operationalized by a reputation variable) and ex post asymmetries (operationalized by a monitoring variable) have shown to be significant and strong antecedents explaining the occurrence of moral hazard. Interestingly, and opposed to the common assumption, the length of a relationship and the amount of direct meetings have not revealed any explanatory significance. Buyer dependency hardly showed influence on supplier opportunism.

Research limitations/implications: Data were collected from a multitude of buyer–supplier relationships from a single firm in the chemical-pharmaceutical industry. Generalizations to other industries still need to be tested. Socially desirable answering behavior cannot fully be excluded because relationship discontinuation is not a desirable situation. In terms of theory implications, this research adds to the notion that both hidden action and hidden intention can lead to moral hazard.

Practical implications: An agency-based analysis can be operationalized with the help of an agency-based supplier classification portfolio. It might be of particular value to firms to discuss those suppliers that scored high in risk of opportunism but did not (yet) reveal any signs of moral hazard. Finally, the strong explanatory power

of reputation alerts buyers to pay more attention to behavioral information on the (potential) supplier available in the market.

Originality/value: Analyzing the occurrence of moral hazard and including terminated relationships adds to the emerging stream of literature on relationship discontinuation in B2B markets. Further, the strong empirical results may encourage researchers to elaborate on principal-agent theory-based assumptions, adding another layer of explanation to buyer–supplier relationships. Findings show that reputation is unduly neglected as supplier selection criterion in current theory and practice.     

Why do buyers share knowledge with suppliers in new product development? current and alternative supplier antecedents

Purpose: Interfirm knowledge sharing has been well recognized to activate the performance and competitiveness improvement of the firms. Previous research has discussed the impacts of current suppliers on buyer–supplier knowledge sharing, but does not explain how this influence occurs. This study aims to disclose the mechanism by which both current and competing suppliers impact buyer–supplier knowledge sharing in buyers’ new product development activities.

Methodology/approach: This study proposed a conceptual model based on relational exchange theory and developed eight hypotheses. Questionnaire survey was used to collect empirical data from R&D staff of Taiwanese electronics firms. This study distributed 1,475 questionnaires and received 246 eligible questionnaires. Structural equation modeling was used to test and verify appropriateness of the proposed model.

Findings: The findings show that current supplier asset specificity positively and directly influences buyer–supplier knowledge sharing in new product development. The current supplier asset specificity also has indirect positive influence on buyer–supplier knowledge sharing in new product development via the mediating effects of buyer trust, satisfaction, and commitment. However, the attractiveness of alternative suppliers only indirectly and negatively affects buyer–supplier knowledge sharing via the mediating effects of buyer trust, satisfaction, and commitment.

Research limitations/implications: This study surveyed the firms in Taiwanese electronics industry. Nevertheless, new product development activities are executed by electronics firms in numerous countries and firms in various industries. For validating the generalization of this study’s results, future research can investigate firms in other industries and countries to verify the proposed model and hypotheses.

Practical implications: Current suppliers’ asset specificity is found to exert more influence on buyer–supplier knowledge sharing than alternative attractiveness. The findings imply that current suppliers should focus on investing specific assets for buyers other than stress the attractiveness and threat of competing suppliers.

Originality/value/contribution: This study initiates to approach the antecedents and influence mechanism of current buyer–supplier knowledge sharing via both perspectives of current and competing suppliers.     

Considering Technological Impacts When Selecting Food Suppliers: Comparing Retailers' Buying Behavior in the United States and Europe

Purpose: The research investigates the impact of emergent technologies, specifically supply-chain technology and food-production technology (i.e., genetically modified organisms [GMO]), on global food retailers' supplier decisions.

Methodology/approach: Qualitative research is conducted to examine technology-related vendor selection criteria of food retailers in 5 European countries comparing to those in the US.

Findings: Our findings show that global food retailers view supply-chain technology as a competitive advantage and is integrated as an important selection criteria; however, selection criteria differ for food-production technology between the United States and the European countries. European food retailers explicitly oppose food-production technology (GMO), while U.S. food retailers implicitly accept food-production technology. Emerging from this opposing view, global food retailers establish similar criteria for organic food (non-GMO) supplier selection: reliability, distance, consistent quality, and relationships with suppliers.

Research implications: Applying the supplier choice criteria framework (Lehmann and O'Shaughnessy 1982 Lehmann, D. R. and 'Shaughnessy, J. O. 1982. Decision criteria used in buying different categories of products. Journal of Purchasing and Materials Management, 18: 9–14.  [Google Scholar]) to further analyze organic food suppliers, we find that reliability (adaptive criterion), distance (integrative criterion), consistent quality (performance criterion), and relationships with suppliers (economic criterion) are essential, but price is not.

Practical implications: This study suggests that to sustain competitiveness in the global food market, food suppliers not only need to ensure technological compatibility in supply-chain, but also adapt to the local food-production restriction (GMO) and organic food selection criteria preferences.

Originality/value/contribution: Supply-chain technology is strategically important and is adopted by global food retailers for competitive advantage; yet, there are dramatic differences regarding the acceptance of food production technology. This research contributes to the better understanding of how technologies exert significant and strategic weight in the food supplier selection process.     

The impact of retail buyer innovativeness on suppliers’ adaptive selling in Japanese buyer–supplier relationships

Abstract

We investigate the critical role of retail buyer innovativeness in Japanese buyer–supplier relationships and explore its link to suppliers’ adaptive selling, cooperative relationships, and retail competitiveness. Further, we examine how process conflict between merchandizing and store divisions moderates the relationship between retail buyer innovativeness and suppliers’ adaptive selling. This study employs a structural equation model using survey data from 246 heads of merchandizing divisions at Japanese retail companies. Our findings highlight the importance of both mitigating process conflict and facilitating suppliers’ adaptive selling in order to improve Japanese retailers’ competitiveness, especially when buyers are highly innovative.     

How supermarket chains in Taiwan select suppliers of fresh fruit and vegetables via direct purchasing

This research focuses on evaluating the criteria used to select suppliers of fresh fruit and vegetables in the supermarket retail chains in Taiwan via direct purchasing. The research sample consisted of procurement managers from supermarket retailers. Interviews with these managers were conducted to produce the first stage expert questionnaire. Following this, the fuzzy Delphi method was adopted to screen the preliminary criteria and the fuzzy analytic hierarchy process was then used to discover the relative importance of each criterion. Research results revealed the most important supplier selection attributes to be procurement price, product quality, product consistency, and food safety. For suppliers of fresh produce, seeking to develop more collaborative relationships with retailers characterized by mutual advantages and trust need to understand how retailers choose their suppliers.     

Dependence concentration and fairness perceptions in asymmetric supplier–buyer relationships

The purpose of this research is to investigate how a supplier manages its relationships with multiple buyers in a market structure of imbalanced power to achieve market success. Drawing on resource dependence theory and social exchange theory, we argue that dependence concentration (the degree of revenue concentration of a supplier’s multiple buyers) and fairness perceptions (distributive and procedural fairness) work together to impact a supplier’s market performance. The authors develop a structural model and empirically test how dependence concentration and fairness perceptions impact supplier performance with survey responses from 92 suppliers in the food supply industry. The findings show that a balanced set of dependence relationships governed by fair business policies and procedures leads to strong and effective relationships; and effective relationships with multiple buyers, rather than with any specific buyer, impact sales and profit growth in a market structure of imbalanced power.     

The Relationship between Mutual TSI and Interfirm Contracts: The Moderating Effect of Strong Ties

ABSTRACT

Purpose: This study examines the influence that tie strength has on contractual relationships between exchange parties with specific investments and also explores the role of network intensity in contractual relationships between buyers and suppliers. We hypothesize that the relationship between transaction-specific investments (TSIs) and contracts is moderated by network intensity.

Methodology: An empirical test is carried out by analyzing buyer–supplier relationships of manufacturing companies. The construct measures were based on those obtained from prior research, and the reliability and validity were established using exploratory and confirmatory factor analysis. The overall measurement model was then assessed with structural equation modeling using AMOS.

Findings: We focus primarily on contract variables as a governance mechanism that can be affected by the strength of ties among firms and the results of our empirical study indicate that supplier TSIs improve the use of informal contracts while the use of formal contracts undermines the effect on supplier TSIs. In addition, we found that firms with weak ties with their partners in the network are more likely to use both formal and informal contracts than those with strong ties.

Contribution: Our study has several contributions. First, our research improves the understanding of the relationship between TSIs and the choice of contracts as a governance mechanism, especially for mutual TSIs. Second, our research improves our understanding of the network strength in the context of business-to-business relationships extending the understanding of the relationship intensity among firms in a network. Third, we focused on the effects of network intensity on contractual relationships.     

Tradeoffs in Supplier Attribute Ratings in Supplier Selection across Strategic versus Non-Strategic Purchases

ABSTRACT

Purpose: This research identifies a customer perspective that is often ignored, neglected, or undervalued in B-to-B sales – the nature of the product itself. The pivot point is whether the product/service desired is strategic (critical to the company’s mission) or non-strategic (not critical to the company’s mission).

Methodology/Approach: A conjoint analysis was conducted for both types of purchases (strategic and non-strategic), assessing the tradeoffs and espoused preferences of four key attributes involving both the supplier and the product across three performance levels – (1) stability of the supplier, (2) reliability, (3) competitive pricing and (4) product quality.

Findings: The results indicate that B-to-B customers do make tradeoffs between suppliers based on stability, reliability, pricing and product quality. The direction of the tradeoffs depends on whether the purchase is a strategic or non-strategic acquisition. The results suggest that suppliers would benefit from understanding the relationship of their products and services to the B-to-B customer’s mission when the supplier is deciding how to improve performance.

Research implications: Too often there is a disconnect between B-to-B salespeople and their customers resulting in suppliers failing to reach performance goals. The research focuses on the importance of B-to-B salespeople uncovering whether or not the customer considers the nature of the product being considered as strategic or non-strategic to their business. The research helps to explain some of the mixed findings in the supplier selection literature.

Practical implications: The research points to the fact that customers analyze and make decisions differently depending on the type of product. Additionally, the research highlights the importance to customers of understanding the potential legal and financial risk of suppliers. This is important in that traditionally suppliers tend to focus on product features and benefits in their selling efforts. These results indicate that they should spend significant time discussing factors that illustrate legal and financial risk reduction to the customer of dealing with their companies.

Originality/Value/Contribution: The study offers a new look at an age-old problem of enhancing sales performance through a new lens by considering the nature of the product (strategic versus non-strategic) through the perspective of the customer. The findings help to explain the mixed results of previous research. To date, the nature of the product and tradeoffs of attributes that customers are willing to make depending on that product classification have not been the focus, though the results suggest that understanding customer decision-making through this lens may enhance supplier success.     

The Role of Retail Equity,Value and Relational Benefits in Building B2B Relationships in Retailing

Abstract

The present paper aims to examine if variables widely studied in B2C contribute to building strong relationships in B2B markets. Moreover, it analyzes the existence of differences across retailers related to percentage of purchases from the main supplier. Through a personal survey to retail store managers regarding their relationships with their main suppliers, a structural equation model is estimated through PLS to test the hypothesized relations between retail equity, value, relational benefits, trust, and commitment. A multi-group analysis is performed to test the moderating role of the percentage of purchases from the main supplier. Three types of relational benefits identified have unequal influence on relationship value. In particular, special treatment benefits and social benefits, together with retail equity, emerge as the main drivers of value in the relationship between retailers and their main suppliers. The percentage of purchases from the main supplier plays a moderating role in some of these relations. This research provides evidence in the sense that, in the relations held by retailers with their main suppliers, retail equity contributes to relationship value creation. Relational benefits are relevant in building B2B relations since special treatment and social benefits have a positive influence on value that is positively related to trust and commitment. To build strong relations with their customers, suppliers of retailers should mainly concentrate their efforts on building brand equity and providing evidence of the existence of special treatment benefits beyond the service delivered, in view of its ultimate influence on customer trust and commitment.     

Important Dimensions in Ocean Freight Services

Abstract

This paper examines the criteria used by organizational buyers in their choice of suppliers of shipping services for ocean freight transport so widely used in international trade. The study was conducted in Singapore which is known for its heavy reliance on international trade as well as for its high ranking container port facilities. Based on a survey of shipping managers in a cross section of business organizations in Singapore, the study identifies important factors in the choice of a shipping line selected on their heaviest used export route for their outgoing goods. It also provides buyers' evaluation of the preferred carrier on the same attributes to examine the performance gaps in the services offered by the line. The findings thus provide a bench mark for the shipping industry and points toward areas of emphasis in the service strategies of the shipping lines.     

Using Signals to Initiate Importer-Exporter Relationships: Evidence from Vietnamese Importers

ABSTRACT

Purpose: Realizing the existence of information asymmetry in export markets and the use of signals to distinguish high-qualified sellers from low-qualified sellers, this study investigates the effects of signal consistency and signal clarity on exporter credibility, and subsequently, importer relationship intention.

Methodology: Using a survey data set collected from a systematic sample of 418 Vietnamese importers, the authors tested a model hypothesizing the impact of signal consistency and signal clarity on exporter credibility, and subsequently, on importer relationship intention.

Findings: The authors found that signal consistency and clarity have a positive impact on exporter credibility. Signal consistency also enhances the level of signal clarity. They also found that exporter credibility underlies importer relationship intension.

Research Implications: Under the condition of information asymmetry, importers face difficulties in identifying and evaluating the best supplier among available suppliers in order to make the most appropriate selection decision. The findings confirm that signal clarity and consistency can help exporters to overcome such problems. Exporters should ensure that all signals sent to importers are clear and consistent over time to encourage importers to build long-term business relationships with them.

Contributions: The findings of this study add to the literature on signaling in exporter–importer relationships and can serve as an initiation for further research in the area in transitioning economies.     

Relationship Quality—Relationship Value and Power Balance in Business Relationships: Descriptives and Propositions

Purpose: The objective of this study is to develop understanding of the interplay between the perceptions of power balance, relationship value, and relationship quality between retail distributors and their suppliers.

Methodology: The authors applied a phenomenological approach in both qualitative and quantitative data collections and analyses. Key informants in 27 of the dominant retail distributors within 5 Norwegian industries and 50 of their most important suppliers were interviewed.

Findings: The power balance seems to favor the retail distributors. Retail distributors and suppliers tell of somewhat different characteristics pertaining to “best” and “worst” relationships relating to economic-, capability-, and integration-based values as perceived between retail distributors and their suppliers.

Research limitations/implications: The empirical findings indicate the complexity in assessing relationship quality and show a rich basis for further research, thereby contributing to knowledge and insights in characterizing relationship quality when power is asymmetrically distributed between distributors and their suppliers. However, personal interviews may reveal answers at rational, cognitive, and even emotional levels, thus complicating subjective analysis.

Practical implications: The results of the study are important for both researchers and practitioners on both sides of retail distributor–supplier relationships.

Originality/value: This study advances the work on what characterizes relationship quality in asymmetric power business relationships.     

Nature of Buyer–Supplier Relationship: Small Businesses in a Small City

If the proposition of Williamson that “highly standardized transactions are not apt to require a specialized governance structure” (1979, p. 248) is to be accepted, then a discrete transaction market between small business owners and their suppliers can be easily organized in the market. This view essentially nullifies the possibility of there being a relational transaction. In this backdrop, this research attempts to explore the small buyer–supplier relationship in the context of a small city. Keeping embeddedness (Granovetter, Am. J. Sociol., 1985; 91: 481–510) as a theoretical foundation, we explore the social content in an apparently pure economic exchange. Although, earlier attempts (Khoja and Kauffman, J. Small Bus. Manag., 2012; 50: 20–40; Uzzi, Am. Socio. Rev., 1996; 61: 674–698) conformed to embeddedness in transactions between a buyer and a supplier among businesses of various sizes, they largely ignored very small‐size buyers and suppliers owing to the miniscule size of business transactions and less frequent interactions between buyers and suppliers. Based on the grounded theory approach (Strauss and Corbin, Basics of Qualitative Research‐Grounded Theory Procedures and Techniques, 1990), in this study, we conducted in‐depth interviews with 57 very small business owners to develop detailed narratives. These narratives were organized under four themes: Contractual relationship, Strategic information sharing, Caste as a proxy, and Trust Factor. The findings clearly indicate that small business owners foster continued relationships with their suppliers, owing to social conditioning factors.     

The Role of Social Mechanisms in Promoting Supplier Flexibility

Purpose: This study explores a conceptual framework for social mechanisms (trust and shared vision) to induce supplier flexibility (i.e., volume, mix, new product, and delivery flexibility).

Design/methodology/approach: The current study is based on marketing research reviews of social mechanisms and supply chain flexibility literature. To explore these issues, the authors developed and tested hypotheses with data from 162 members of the SMIT (Supply Management Institute, Taiwan).

Findings: The results show that trust has a direct impact on supplier's volume flexibility and delivery flexibility. Furthermore, the findings indicate that a shared vision has direct impact on supplier's mix, new product, and delivery flexibility. Finally, shared vision plays a mediating role among trust and mix, new product, and delivery flexibility.

Research limitations/implications: This research considers buyer's perspective in examining social mechanisms that enhance supplier flexibility. A clear understanding of social mechanisms effects could evaluate competence trust and risk of respective flexibility that may affect social mechanism effectiveness.

Practical implications: This article contributes to management guidelines on how to align suppliers to respond quickly to customer demands.

Originality/value: The study provides novel insights into social mechanism impact on suppliers' respective flexibility.     

Supplier price concessions: A longitudinal empirical study

The competitive nature of today’s business-to-business markets requires companies to continually look for ways to reduce costs; one of the easiest of which is to demand price reductions from suppliers. In this research, price reduction demands and the corresponding concessions given by 238 suppliers to the six major North American Automotive original equipment manufacturers during 2001–2007 are analyzed utilizing a simultaneous equation model. The three stage least squares estimates indicate that suppliers are willing to give higher price concessions when buyers align specific interfacing characteristics and processes with their suppliers so that the suppliers perceive greater opportunities for future business and profit. These results provide, for the first time, an understanding of the dynamic nature of the impact of buyer–supplier relational components on supplier price concessions.

The delisting of products by retail buyers

The main aim of the research reported here is to identify any patterns in the delisting behaviour of retail buyers, where a delisted product is defined as one which is removed from sale by a retailer but which continues to be sold by other retailers. The influence of the retail buyer in the marketing of consumer products has become ever more significant. Much academic research into retail buying has aimed at identifying criteria that affect purchasing decisions but few generalizable findings have emerged due to the context‐specific nature of such decision making. In this research a specific context is chosen, that of the de‐selection or delisting of products, a topic that has received little attention to date.

The results of interviews with 125 buyers, working for large and small retailers, on their reasons for 290 examples of product delistings are reported. The influence of more detailed contextual variables such as the buyer's age, experience and qualification, the product type, and the source of the product are examined together with a number of reasons for delisting the product. Many of these contextual variables, particularly the size of the retail business and whether the buyer had experience of working in a retail outlet, correlated widely with the relative importance of decision variables. Buyers working for smaller retailers tended to delist because of low sales volumes. Nett profitability, the reason why products should be delisted, was rarely cited as a major criterion.

More detailed analysis of the data set using factor and cluster analysis revealed that delisting decisions could be categorized into two types, each defined by combinations of contextual and decision variables. The most important variables in distinguishing between the two types of decisions were the buyer's age and experience as a buyer (contextual variables) and the decision criteria of nett margin being too low or the selling price to the retailer being too high. Younger, less experienced buyers were more likely to delist products because of low nett margins and high buying prices. Older, more experienced buyers were likely to delist for reasons other than these. The implications for retailers and for their suppliers of both the major and minor findings from the study are discussed.     

An investigation of the cross-border supplier development process: Problems and implications in an emerging economy

This paper is concerned with supplier development in an emerging-market. The context of the study is the interaction between Pakistani suppliers and Japanese automotive manufacturers in equity joint ventures operating in Pakistan. Using a novel approach, drawing data from buyers ‘and’ suppliers, the paper presents a three-stage (evaluation, exploration and interactive) teleological process theory that highlights the key relational, knowledge transfer, and operational factors that signify each stage. Key conclusions are drawn as to the importance of relational ties, and the early importance of absorptive capacity. Notions of stasis implied by predominantly cross-sectional research into supplier development are challenged and the findings reveal many factors that demonstrate temporal dynamics. The paper also highlights CSR dilemmas for developed-country investors who are establishing supplier development programmes in developing economies.
