The ‘T-Shaped Buyer’: A transactional perspective on supply chain relationships

This paper challenges the normative view of interdependent buyer-seller relationships and provides a more holistic perspective of the contextual reality that shapes buyer behaviour. By proposing an innovative qualitative methodology, which focusses on boundary-spanning, pre-sales interactions, the research penetrates complex and commercially sensitive buyer-seller relationships. The longitudinal research design uses web-based diaries and follow-up interviews to explore conditions of power based interdependence between buyers and sellers. The ensuing data is mapped using qualitative content analysis and the results are aggregated graphically for assessment. Using this approach the study develops a nuanced view of the dominant patterns of buyer behaviour, and challenges the opinion that a search for competitive advantage will strengthen cooperative relationships in conditions of power based interdependence. The paper introduces the metaphor of the 'T-Shaped Buyer' to explain the empirical findings and, while acknowledging the contextual limits of the study, suggests that this metaphor may cause both academics and practitioners to reflect on normative thinking.     

Multilayer analysis of supply chain strategies’ impact on sustainability

Integrating lean, green and resilient strategies into Supply Chain (SC) decisions is a key success factor for transformation toward sustainability. These strategies are increasingly common in the SC, although their implementation and results are not the same across different SC levels (Tier 1, 2 and 3 suppliers and the focal company). In spite of this, earlier studies have not explored in detail their effects on environmental, economic and social sustainability dimensions nor differentiated between SC levels and therefore implementation strategies overlook the difference between these levels. Accordingly, a novel multilevel analysis of the aerospace manufacturing SC based on Interpretive Structural Modeling (ISM) is carried out. This approach allows exploring the effects of combining lean, green and resilient strategies on specific sustainability performance measures in the aerospace manufacturing SC. The findings reveal differences between SC levels on the effects of lean, green and resilient strategies on the different sustainability dimensions. Additionally, Tiers 2 and 3 show a higher resistance or lower implication in the development of lean, green and resilient strategies than the focal company and Tier 1 companies. Final ISM models become a useful tool for managers to specifically establish coordinated long-term SC sustainability programs for each SC level.     

Does the configuration of macro‐ and micro‐institutional environments affect the effectiveness of green supply chain integration?

Despite the importance of the general environment in affecting the effectiveness of green supply chain integration (GSCI), our understanding of the roles of different configurations of macro‐ and micro‐institutional environments remains limited. Based on institutional theory and resource mobilization theory, this study examined the moderating effects of the configurations of macro‐ and micro‐institutional environments on the GSCI performance link employing both a configuration and a contingency perspective. Our findings from a longitudinal survey of 206 Chinese manufacturing firms provide empirical evidence for the coexistence and nature of macro‐ and micro‐institutional environments and their moderating effect on the GSCI performance link. Specifically, the results revealed that Chinese manufacturers can be clustered into three groups with different macro‐ and micro‐institutional environments (i.e., cognizant, sensible, and conscious manufacturers). Furthermore, the configuration of macro‐ and micro‐institutional environments moderates the effect of green supplier integration on social performance, as well as the effects of green customer integration on financial, environmental, and social performance. This study contributes to both the GSCI literature and practices.     

For green or not for green? The effect of cooperation goals and type on environmental performance

Although many scholars have demonstrated that companies engaged in collaborations achieve better environmental performance than other companies, existing studies have not analyzed in depth whether this effect changes considering the characteristics of cooperation. Our paper aims to explore whether collaboration with other companies always has a positive effect on environmental performance or whether it depends on cooperation goals, collaboration type, or company size. Empirical analysis based on a sample of 773 European companies demonstrated that an external source of knowledge is an important way to foster firms' environmental proactivity, especially when environmental goals are shared at the basis of collaboration. Second, we verified that companies involved in JVs with environmental goals achieve greater environmental performance than companies that use M&As to acquire external knowledge. Finally, we demonstrated that it is more important for small companies to be involved in environmental collaboration than larger ones.     

The strategies of supply chain risk management – a synthesis and classification

This paper conducts an in-depth systematic literature review of 86 peer-reviewed academic journal articles on supply chain risk management (SCRM) strategies from 2000 to mid-2015. The findings indicate a variety of dispersed supply chain risk (SCR) mitigating strategies and suggest a more homogeneous use of terminology. Moreover, the analysis also reveals insufficient evidence for the effect of SCRM on performance. The current study groups and synthesises the various SCRM strategies into proactive and reactive approaches for the ante and the post disruption state and classifies them according to the different supply chain types. Altogether the findings provide essential practical and theoretical contributions to strategic responses to adverse incidents by creating a unique conceptual framework of SCRM strategies and providing direction towards promising areas of research.     

Framing Sustainable Supply Chain Finance: how can supply chain sustainability practices and supply chain finance solutions be integrated?

Supply chain finance (SCF) can play a role in improving supply chain (SC) sustainability. That is why academics have started investigating the connection between SCF and sustainable SC management, and practitioners have begun developing new SCF solutions with a sustainable orientation. Although SCF solutions have been suggested as supporting tools for the diffusion of sustainability within SCs, academic contributions have only partially investigated sustainable SCF (SSCF). There is the need to understand in greater detail first, how different SC sustainability practices (e.g., supplier assessment, supplier development, incentives to suppliers, and third-party involvement) can be integrated into SCF solutions; second, how different brokerage roles can facilitate this integration to contribute to the successful implementation of an SSCF solution. This paper investigates those aspects through multiple international exploratory case studies. The results confirm that SCF solutions become sustainable by integrating different SC sustainability practices, either embedded in the SSCF solutions or reinforced by the implementation of the solutions. Moreover, involving new actors, including third-party information providers, NGOs, and certification bodies, who assume different brokerage roles, positively influences the development of SSCF solutions.     

Achieving supply chain ‘Leagility’ through a project management orientation

Many forces have combined to make today's supply chains more complex than ever before. These forces include the significant trend to out-sourcing; the growth of offshore manufacturing and procurement; the rising demand for customer-specific solutions and the globalisation of markets. The paper highlights the challenges that organisations must address in order to gain and retain competitiveness in today's markets – in particular, the need to achieve ever lower costs while simultaneously enhancing responsiveness. In other words, the need is to develop hybrid supply chains that are both ‘lean’ and ‘agile’. Using a single case study of a global telecommunications company as an example, the authors demonstrate how supply chain complexity can effectively be mastered by adopting a project management orientation and in the process enabling outcomes that are ‘leagile’, that is, both lean and agile.     

The effect of human resource practices on perceived organizational support in the People’s Republic of China

Using a sample of workers and managers employed by a hotel located in Southeastern People’s Republic of China, we investigated the relationship between various human resource management practices and the perceived organizational support (POS) experienced by the employees. We then investigated the effects of POS on employee satisfaction. Our data suggest that hiring practices, training, and compensation practices predict POS. These results are consistent with previous research. We also found that POS influences worker satisfaction and acts as a mediator between select HR practices and satisfaction. This study contributes to the literature by replicating Western-based findings with a Chinese sample and illustrating that the attitudes of Chinese employees can be influenced through the use of HR practices.     

The challenge of cyber supply chain security to research and practice – An introduction

The tremendous potential to assist or degrade economic and national security performance make security in the cyber supply chain a topic of critical importance. This is reflected by the tremendous activity in the public and private sector to better understand the myriad of cyber challenges, identifying existing gaps and needs and closing these gaps as quickly and firmly as possible through government policy initiatives, public/private partnerships, and legal/insurance penalty and incentive regimes. However when we examine the academic literature, the research and publications in this area are rather sparse. Consequently, this special issue on Security in the Cyber Supply Chain is intended to act as a resource to practitioners and as a call to research.     

Could lean practices and process innovation enhance supply chain sustainability of small and medium‐sized enterprises?

Small and medium‐sized enterprises (SMEs) adopt lean practices (LP) to reduce waste across their organisational value chain, which helps achieve sustainability. Process innovation (PI) has also been applied through cleaner production, environmental management system, ecodesign, and so on to address both customers' needs and legislations by policymakers. Although prior studies reveal the effect of sustainable practices, LP, and PI on sustainable performance separately, less is known on the integrated effect of them on sustainability performance. Moreover, studies on mediating effect of LP and PI on sustainability performance are scant. This is significant as LP and PI are considered to be the enablers for achieving sustainability performance. This research addresses this knowledge gap. The research first theorises a model integrating these four major constructs (sustainability practices, LP, PI, and sustainability performance) through hypotheses development. Subsequently, using structural equation modelling, it is tested whether each of sustainability practices, LP, and PI effect sustainability performances. Additionally, mediating effect of LP and PI between sustainability practices and performances is derived. The study uses data from 119 SMEs within manufacturing industries in the Midlands, United Kingdom. Further, a few case studies have been undertaken to validate the findings from quantitative analysis. The overall results show that although sustainability practices, LP, and PI help achieve sustainability performance of SMEs supply chain through efficiency and responsiveness respectively, the mediating effect LP is more compared with PI. Moreover, SMEs adopt LP when they are economy focused and implement PI when they are pressurised by customers and/or policymakers.     

Mapping supply dynamics in renewable feedstock enabled industries: A systems theory perspective on ‘green’ pharmaceuticals

This paper provides a multi-stage multi-layer mapping methodology for capturing the macro-level supply chain dynamics that govern industrial systems using renewable feedstocks. The mapping approach combines the Industrial Systems Mapping and System Dynamics principles to systematically capture the interrelations across: (i) institutional players, (ii) sector specialists, (iii) products and intermediates, (iv) production operations, and (v) firms within the supply chain. The interfaces are further explored at four interconnected and mutually interacting theme areas of analysis, namely: (i) renewable chemical feedstocks, (ii) production technologies, (iii) target markets, and (iv) value and economic viability. We demonstrate the applicability of our approach by mapping the dynamics in industrial systems for the production of ‘green’ pharmaceuticals, particularly via the illustrative case of paracetamol. Through the use of the proposed integrated mapping process the case study demonstrates the principal interrelationships and inter-firm dynamics between the different layers of analysis. Three main drivers are identified that could enhance supply network transformations for improved viability of these developing industrial systems, namely: (i) regulatory conformance with market requirements, (ii) system level feasibility assessment of given renewable feedstocks, and (iii) target market volume demand. The causal feedback elements of the provided mapping technique indicate that it could support the analysis of industrial systems’ transformation dynamics enabled by renewable feedstocks. The standardisation of the methodology and its elements provides for an effective visualisation technique with cross-industry relevance.     

The relationship between ‘high-performance work practices’ and employee attitudes: an investigation of additive and interaction effects

In order to improve our understanding of mediating variables inside the ‘black box’ of the firm's labour management, this paper examines the relationship between high-performance work system (HPWS) practices and employee attitudes. Using a randomly selected, national population sample, clear evidence was found for a positive relationship between HPWS practices and the attitudinal variables of job satisfaction, trust in management, and organizational commitment, implying that HPWS can provide win-win outcomes for employees and employers. However, the study also tests – from an employee perspective – the ‘complementarities thesis’ and finds negative interaction effects among HPWS practices. This strengthens the argument that there are likely to be limits to the positive outcomes of HPWSs for employees. Evidence of sequencing in the employee attitudinal responses to HPWSs was also found, with job satisfaction as the key mediating variable.     

An empirical analysis: Did green supply chain management alleviate the effects of COVID-19?

Supply chain management played a central role during the COVID-19 crisis, as the outbreak of the pandemic disrupted the majority of all global supply chains. This paper tests whether companies that use green supply chain management (GSCM) practices benefited from a buffer effect in the context of COVID-19. Our empirical analysis, conducted on a sample of U.S. companies, shows that GSCM companies experienced less negative abnormal stock returns during the crisis. This result contributes to the literature on financial impact of GSCM, finding that GSCM is perceived as an effective risk management tool and can serve as an effective drug against COVID-19 crisis. Our paper also contributes to the business debate on the role of green supply chains in the post-COVID19 world.     

The effect of oil supply shocks on US economic activity: What have we learned?

Estimated responses of real oil prices and US gross domestic product (GDP) to oil supply disruptions vary widely. We show that most variation is attributable to differences in identification assumptions and in the model specification. Models that allow for a large short-run price elasticity of oil supply imply a larger response of oil prices and a larger, longer lived contraction in US real GDP. We find that, if we condition on a range of supply elasticity values supported by microeconomic estimates, the differences in the oil price responses diminishes. We also examine the role of lag length, of using pre-1973 data, alternative measures of real economic activity and using the median response function instead of the modal structural model.     

Is EDI dead? The future of the Internet in supply chain management

I have been involved in materials management for about 30 years (that is not something many of us really want to admit--it says we are getting old), and over that time I have seen many methods of communication come and go. In the 1960s, we used seven-part carbon forms to generate orders. We also used the keypunch card or IBM card to send our request for materials to our supplier. The supplier would acknowledge our order and provide us with a promise date. This could be done by mail using these cards or by forwarding the information to us electronically for conversion to cards. I could trace the history of communication in painful detail, but that is not important. What is important is that the only thing that has remained constant in those past 30 years has been change. We have all heard that before, but we seem to forget it. This presentation will look at the future of EDI and the Internet in supply chain management.     

The effect of economic policy uncertainty on China’s housing market

This study examines the relationship between economic policy uncertainty (EPU) and housing price at the macro-level in China as a developing country. The empirical evidence indicates that EPU has a leading effect on China’s housing market. In general, the housing market is prosperous when economic policy is stable and there is a positive relationship between housing price variation and EPU, which means housing market risk grows under unstable economic policies in this developing economy. Moreover, economic policy variation affects low-amplitude changes in housing prices. A variation of policy uncertainty enhances the risk premium of the housing market. By contrast, the level of EPU influences high-amplitude changes in housing prices, which reflects the trend of EPU dominating China's housing market.     

The effect of NYSE listing on a firm’s media visibility

The most frequently cited reason by corporate managers for switching their firm’s trading location from Nasdaq to the NYSE is to improve visibility. This study examines whether these perceptions about listing are real or illusory and whether firm size affects media visibility. Based on a large sample of firms that listed on the NYSE compared with a matched sample of firms remaining on Nasdaq, the results show that NYSE listing does not lead to gains in media visibility during the period immediately after listing. Over a longer period, small- and medium-sized firms experience significant gains in media visibility compared with large firms. Additional tests show that increased media coverage is attributable much more to the rapid earnings growth before listing than to listing. Therefore, managers erroneously attribute the visibility gains to NYSE listing.     

Cyber supply chain security practices DNA – Filling in the puzzle using a diverse set of disciplines

This paper describes the journey of the evolving cyber supply chain community towards creating practical and useful standards and best practices. It is based on the author?s experience working on the topic since 2006 and contains observations and lessons learned, refined over the years. Cyber supply chain security requires members of several different professional communities to come together including information security, system and software engineering, supply chain and logistics, and process improvement, to name a few. These professional communities have not worked or interacted before and had divergent experiences, vocabularies, frameworks, standards, ways of demonstrating that the practices were performed, and many other things. Over the years these people have learned that many practices that they thought were missing already existed in another discipline and that reinventing them was not necessary. The paper will summarize this journey with the goal of helping those new to this subject matter learn from those who have been working on it for some time.     

The peer-firm effect on firm’s investment decisions

This study investigates the effect of peer firms on firm investment strategies. We test the peer group effect hypothesis along differing levels of financially constrained firms as well as differing degrees of industry competition. Using idiosyncratic equity returns as the instrument variable, we use 2-stage least squares regression to identify the influence of peer firms’ investment decisions on a firm’s own investment policies. Our analyses empirically confirm that there is a peer group effect in making firm investment decisions. More financially constrained firms show greater dependency on peers’ investment decisions. Tests of peer sensitivity to the increase in industrial competition, however, displayed a U-shaped quadratic curve, which shows that firms have the lowest peer group effect in medium-competition markets. We claim that imitative behavior in investment is presumably weak in the mid-competition market because firms are yet to be distinguished in this market.     

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.
