Integrating Strategic Carbon Management into Formal Evaluation of Environmental Supplier Development Programs

Increasing global environmental pressures from regulators, markets and communities have caused focal companies in supply chains to recognize the significance of environmentally conscious management. Greener supply chains are part of this recognition. Environmental supplier development is a valuable and viable strategy for greening supply chains. However, low carbon management is rarely explored in supplier development. Further, formal tools and models for focal companies to evaluate environmental supplier development programs (ESDPs) considering low carbon management and their effect on supplier performance improvement are limited. To help address these gaps in the literature, this paper proposes a portfolio evaluation model for ESDPs that consider three types of supplier performance: traditional operational factors, traditional environmental factors and low carbon management factors. This model applies the fuzzy scoring method to measure the effect of ESDPs on supplier performance, and uses fuzzy DEMATEL to examine the cause–effect interrelationships among the ESDPs. Subsequently, a real world example is used to demonstrate the application of the portfolio model and provide insights into environmental supplier development evaluation, followed by discussions of case application results. This paper concludes with directions for further research. Copyright © 2014 John Wiley & Sons, Ltd and ERP Environment     

COMPETITION LAW AND COMMODITY MARKETS: THE CASE OF WHOLESALE ELECTRICITY

This paper considers some of the challenges that the exercise of market power in commodity markets poses for public policy, focusing on the case of wholesale electricity. The particular economic characteristics of electricity markets can give rise to market conditions where the price elasticities of both demand and supply are very low. Under such conditions, it may not be necessary for a supplier to have control over a large share of available capacity to be able to exercise substantial market power. This paper questions whether the two principal existing forms of supervision of these markets, Competition Law and financial regulation, are sufficient to address the types of problems that can be expected to arise given these characteristics. The answer to that question is in the negative.     

Public procurement for innovation through supplier firms' sustainability lens: A systematic review and research agenda

Public sector purchasing processes are gaining increasing prominence as a demand-side innovation tool for addressing national sustainability challenges. Accordingly, there has been growing research attention to this topic. Prior studies suggest three key rationales that underlie the use of public sector procurement to drive innovation: (i) the buyer–user rationale (for creating new needs); (ii) the market/system failure rationale (for improving suppliers' capacity to innovate); and (iii) the public services rationale (for improving public services). However, operational activities at the upstream supply chain affecting the sustainable innovation capacities of supplier firms appear to be under-researched in the public procurement for innovation (PPI) scholarship, despite knowledge about innovation capacity being critical to successfully implementing PPI. This paper adopts a systematic literature review approach to synthesise existing fragmented literature on sustainability-oriented PPI, focusing on supplier perspectives. Findings from a synthesis of 41 relevant articles suggest, among others conditions, that a procurement framework that maintains a good balance of competition and innovation, builds buyer–supplier relationship and urges strong supply networks, maintains a stable political commitment, offers security for niche markets with effective innovation risk management culture would enhance suppliers' sustainability capacity and propensity to innovate. This paper contributes to the PPI literature and the literature on determinants of sustainable innovation systems from supplier firms' sustainability lens.     

The moderating effects of supplier portfolio characteristics on the competitive performance impacts of supplier-facing process capabilities

We draw on the interorganizational relationship management literature to examine how contextual characteristics of the supplier portfolio (portfolio concentration, relationship length, and supplier substitutability) moderate the impacts of process alignment and partnering flexibility – two of a firm's key supplier-facing process capabilities to manage supplier relationships – on a product line's competitive performance. Our analysis of survey data on a firm's supplier portfolio for a major product line indicates that the impacts of process alignment and partnering flexibility on competitive performance are moderated by the three supplier portfolio characteristics. Specifically, while concentrated relationship portfolios, long-term relationships, and supplier substitutability amplify the positive effect of process alignment on competitive performance, concentrated relationship portfolios and long-term relationships attenuate the competitive benefits that firms derive from partnering flexibility. While long-term relationships and concentrated supplier portfolios enhance the competitive benefits of process alignment, operations managers also need to recognize the detrimental effects of these supplier portfolio characteristics on the competitive benefits of partnering flexibility.     

Managing competitive software component supplier relationships

This study addresses purchasing challenges faced by companies buying commercial software components. The purpose is to find out how we can understand the purchasing challenges in software component business. First we develop pre-understanding based on knowledge on competitive supplier relationships and competitive bidding. This is elaborated empirically through a qualitative case study. We contribute to prior literature by concluding that the nature of software component supplier relationships is influenced by the object and costs of exchange. We also argue that, in markets like software component business, it is essential to pay attention to the development of the whole supply market.     

A contingent theory of supplier management initiatives: Effects of competitive intensity and product life cycle

Direct investments in supplier development and close relationship building are the two major collaborative supplier management strategies for developing and accessing superior supplier capability. The impact of these two strategies, however, has not been uniform across firms, calling for a deeper examination of their relative effectiveness. Utilizing multiple theoretical frameworks, this study examines the relevance and effectiveness of the two collaborative strategies across the growth and maturity stages of the product life cycle (PLC). Specifically, the study analyzes the influence of competitive intensity as an antecedent to supplier development and relational initiatives, and the role of product life cycle as a moderator of the inter-relationships among competitive intensity, supplier development, relational initiatives, and supplier capability. Based on primary survey data, and discussion with practicing managers, the study finds that the individual and integrative effectiveness of supplier development investments (SDI) and relational orientation (RO) can be influenced differently by competitive intensity and PLC stage. In particular, RO can have a foundational role in motivating SDI for superior supplier capability, as also in safeguarding against supplier opportunism in the standardized product market context of the maturity stage. The managerial and theoretical implications of varied emphasis on the two collaborative supplier management strategies across the PLC stages are discussed.     

The role of supply management innovativeness and supplier orientation in firms’ sustainability performance

Questions about the influencing factors and measurement of firms' sustainability performance have attracted growing research interest, as the requirements for sustainability have steadily increased. This study examines whether supply management innovativeness and supplier orientation make positive impacts on firms' overall sustainability performance. An empirical study based on a survey targeting large- and medium-sized manufacturing companies in Finland shows that innovativeness in supply management considerably influences a firm's overall sustainability performance and that supplier orientation positively relates to sustainability performance. The benefits of innovativeness in supply management and strategic supplier orientation are directly realised in sustainability performance. Therefore, supply management is not only a gatekeeper against sustainability risks arising from the supply base but is also a function by which new ideas aiming to influence supply markets and firms' sustainability are presented.     

Managing supplier sustainability risks in a dynamically changing environment—Sustainable supplier management in the chemical industry

Varying definitions and interpretations of sustainability standards have become a major concern for purchasing and supply management (PSM). As the foremost interface to an increasingly global supply base, PSM plays an important role in the mitigation of sustainability-related risks. By conducting responsible purchasing and supplier management, the risk of corporate reputational damage to the buying firm, caused by supplier misconduct, can be avoided. However, resources for effective risk-mitigation are limited and the applicability of supply risk assessment and supplier assessment methods have not been evaluated for sustainability. In this paper, we explore how leading PSM functions identify, assess, and treat supplier sustainability risks and elaborate on the integration of sustainability risk management in supplier management processes. Based on the findings from a multiple case study in the chemical industry and by drawing on the dynamic capabilities view (DCV), we propose that mature and sustainable supplier management capabilities are a source of competitive advantage in terms of lower exposure to reputational risks and enhanced operational performance.     

Supplier development and cost management in Southeast Asia—Results from a field study

This paper is about supplier development when international companies have production sites in Southeast Asia and look for opportunities to switch from international suppliers to local suppliers. We conducted a field study involving site visits to companies in Thailand and Vietnam, and interviews at corporate supply chain departments. Some key observations are: cost management was a dominant motive for taking local supplier development initiatives. Furthermore, local sourcing and local supplier development were important for international companies to improve access to local customer markets. Firms deliberately assessed whether a particular supplier would likely be able to improve sufficiently to warrant investing in supplier development, which typically involved a combination of initiatives, requiring the international firm to take considerable efforts. Local sourcing strategies and priorities for supplier development initiatives tended to focus on items with low supply risk and low volume. These findings are discussed based on transaction cost economics, and we suggest that firms use several ways to reduce the risk of transaction-specific investments in supplier development initiatives.

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.     

Sole sourcing,competitive sourcing,parallel sourcing: Mechanisms for supplier performance

Quality management practitioners in the USA such as W. Edwards Deming, strongly advocate the Japanese model of supplier relationships-recommending substantial specific investment in a single supplier for improved co-ordination and higher quality. But the strategy literature and conventional wisdom favor multiple sourcing, suggesting that a high level of specific investment in a sole source will lead to problems with supplier performance. Using agency theory, we construct a model to evaluate the tradeoff between the costs to set up and coordinate with suppliers and the incentive for performance provided by competition. We find that the validity of Deming's Point Four, that sole sourcing is more profitable than competitive sourcing, depends on parameters such as profit sensitivity to supplier performance.

New Public Management

The paper presents an assessment and evaluation of what is termed ‘new public management’ at the end of the 1990s. In order to provide this assessment, new public management is defined in several ways: as a movement, as an academic commentary, and as reformed organizational practice in the public sector. The paper uses the UK health sector to examine some of the assumed relationships between ideology, actions and consequences implied within a broad understanding of new public management. Developments in the UK health sector are used to address assumptions focusing on different aspects of the ideology (private sector practices and markets can increase efficiency in the public sector), actions (introduction of market mechanisms and business-like, practices) and consequences (operational performance, strategic direction, governance and values). Drawing on developments in the UK health sector, an assessment of new public management at the end of the 1990s sees it much diversified and expanded from original conceptions, which are ensuring its contested survival as a movement, as an academic commentary, and as reformed organizational practice in the UK despite a change of government in 1997.     

Wholesale price discrimination: Innovation incentives and upstream competition

In intermediate good markets where there are alternative supply sources, wholesale price discrimination may enhance innovation incentives downstream. We consider a vertical chain where a dominant firm and a competitive fringe supply imperfect substitutes to duopoly retailers which carry both varieties. We show that a ban on price discrimination by the dominant supplier makes uniform pricing credible and reduces retailers’ incentives to decrease the cost of acquiring the competitively supplied variety, leading to higher upstream profits and lower downstream welfare. Our analysis complements existing results by identifying a novel channel through which wholesale price discrimination can improve dynamic market efficiency.     

Technical efficiency and the competitive behavior of hospitals

This paper examines whether the competitive behavior of hospitals influences the extent to which their productive efficiency deviates from best-practice standards. An index of technical inefficiency is constructed by means of Data Envelopment Analysis (DEA) for 189 acute-care hospitals in the State of Florida in 1989. A regression model is then specified that estimates the impact of competitive dynamics in local hospital markets over the period 1982–1988 on these 1989 DEA efficiency scores, controlling for a set uf internal and external constraints on managerial decision making. Among other things, the empirical analysis shows that these ratings are systematically accounted for by both the nature and vigor of hospital competition, with price leaders in highly competitive markets in particular shown to be more efficient. The public policy implications of these findings are discussed.     

The effects of supplier-to-buyer identification on operational performance—An empirical investigation of inter-organizational identification in automotive relationships

Over the past decade conceptual and empirical research in operations management has embraced the idea that collaborative supplier-buyer relationships are a source of competitive advantage for manufacturing firms. Anecdotal evidence from the Japanese and U.S. automotive industry and emerging research suggests that inter-organizational identification of suppliers with their buyers, termed supplier-to-buyer identification, is an unexplored factor of relational advantage. This study presents a model and empirical test that supplier-to-buyer identification fosters superior operational performance by enhancing trust, supplier relation-specific investments, and information exchange. Through a survey of 346 automotive supplier-buyer relationships, the findings show that supplier-to-buyer identification directly impacts supplier relationship-specific investments and information exchange, although most of the latter effect is mediated by trust. The findings also indicate that supplier relation-specific investments and information exchange play different but complementary roles in influencing operational performance. The results suggest new directions for supplier-buyer relationship research in operations management and important managerial implications.     

New evidence on innovation and market structure

Arrow and Demsetz have disagreed on theoretical grounds as to whether the incentive to invent is likely to be greater in a competitive industry or a monopoly one. Past empirical studies of the relationship between the rate of innovation and market structure have suggested that innovation occurs at a faster rate within a competitive market structure. This paper employs more detailed data and a larger sample of markets than have most previous studies of this relationship. Using a sales-weighted measure of innovation, the paper finds a positive and statistically significant relationship between the overall rate of innovation In individual markets and the level of seller concentration. This implies that public policy which reduces concentration may, through its impact on incentives, have the side effect of reducing the rate of innovation in the markets involved.     

Purchasing practices in small- to medium-sized enterprises: An examination of strategic purchasing adoption,supplier evaluation and supplier capabilities

The benefits that can be derived from effective purchasing have long been recognised in the management literature. Despite a growing body of research on purchasing practices in small- to medium-sized enterprises (SMEs), a number of key issues remain under-examined. We investigate SME purchasing practices in terms of (1) the degree to which purchasing is regarded as a ‘strategic’ activity by SMEs, (2) the use of supplier evaluation systems by SMEs and (3) the supplier capabilities emphasised by SME buyers. Through a survey of UK SME managers, we find that purchasing practices varied greatly across SMEs. Purchasing formality is generally low with limited evidence of purchasing being employed strategically and with many firms not undertaking formal supplier evaluations. In terms of supplier capabilities, we find that SMEs differ in the capabilities they prioritise, with three distinct groups evident. These groups are labelled ‘holistic’, ‘process’ and ‘logistics’ based on the supplier capabilities they emphasise. These three groups of firms also differed in terms of the emphasis they placed on strategic purchasing, supplier evaluation, technological focus and how they compete in their main markets, but not in terms of firm size or number of suppliers utilised. The implications of these findings are discussed and areas meriting future research are proposed.
