The purpose of this paper is to develop a comprehensive framework that synthesizes approaches and contingency variables to manage the sustainability of multi-tier supply chains and sub-suppliers.

Using a systematic literature review, the authors analyse 39 studies and relevant theories to develop a comprehensive framework that integrates research efforts so far.

The authors build a conceptual framework that incorporates four approaches to manage the sustainability of multi-tier supply chains. They also identify several contingency variables (e.g. power, dependency, distance, industry, knowledge resources) and their effect on the proposed approaches.

Based on the framework, six research propositions that advance the theories on multi-tier supply chain management, allow lead firms to develop comprehensive sustainable supply chain strategies and set the ground for future research in the area were developed.

This study provides a novel framework for studying sustainability in multi-tier supply chains that goes beyond the single-tier perspective and incorporates the extended supply chain.

The purpose of this paper is to systematically review and assess the current status of research on supply chain sustainability from a network structural perspective and provide an organising framework for future scholarship in this area.

By adopting an evidence-based approach, this study conducts a systematic review of 73 articles from 18 peer-reviewed journals published between 2000 and 2020.

Adopting a social network analysis approach, the review identifies specific node-level (i.e. degree centrality, closeness centrality and betweenness centrality) and network-level (i.e. network density, network sub-groups and network diversity) structural properties that play a role in supply chain sustainability. The results reveal that structural properties determine the extent of perception of sustainability risks, the diffusion of sustainability targets, introduction of sustainable innovations, development of sustainability capabilities, adoption of sustainability initiatives and the monitoring of sustainability performance throughout the supply chain.

By distinguishing between supply network and sustainable supply network types, this study extends the existing understandings of the role of network connectivity patterns in supply chain sustainability through synthesising and evaluating the extant literature. This study further clarifies the role of these network structural properties in supply chain sustainability by describing their impact on a set of sustainable supply chain management practices through which firms achieve sustainability goals across their supply chains.

The purpose of this paper is to examine how first-tier suppliers in multi-tier supply chains adapt their vertical and horizontal relationships to reduce the risk of slavery-like practices.

Using Archer’s morphogenetic theory as an analytical lens, this paper presents case analyses adduced from primary and secondary data related to the development of relational anti-slavery supply capabilities in Brazilian–UK beef and timber supply chains.

Four distinct types of adaptation were found among first-tier suppliers: horizontal systemisation, vertical systemisation, horizontal transformation and vertical differentiation.

This study draws attention to the socially situated nature of corporate action, moving beyond the rationalistic discourse that underpins existing research studies of multi-tier, socially sustainable, supply chain management. Cross-sector comparison highlights sub-country and intra-sectoral differences in both institutional setting and the approaches and outcomes of individual corporate actors’ initiatives. Sustainable supply chain management theorists would do well to seek out those institutional entrepreneurs who actively reshape the institutional conditions within which they find themselves situated.

Practitioners may benefit from adopting a structured approach to the analysis of the necessary or contingent complementarities between their, primarily economic, objectives and the social sustainability goals of other, potential, organizational partners.

A range of interventions that may serve to reduce the risk of slavery-like practices in global commodity chains are presented.

This paper presents a novel analysis of qualitative empirical data and extends understanding of the agential role played by first-tier suppliers in global, multi-tier, commodity, supply chains.

This study aims to investigate the under-researched role of the sub-supplier’s direct environment in achieving compliance with multi-tier sustainable supply chain management (MT-SSCM) objectives.

Building on conceptual research, this study aims to generalize the characteristics of multi-tier supply chains in light of institutional theory and supply chain (SC) uncertainty to enhance the understanding of their complex interrelationship.

A three-dimensional framework is built around the supply and demand uncertainty as well as the pressures for sustainability exerted by the supplier’s direct environment to propose ideal constellations for the application of MT-SSCM. Moreover, research directions and implications for the alteration of suboptimal constellations are developed.

Incorporating the supplier’s environment in the choice of MT-SSCM practices couples the sustainability priorities of the focal firm and the supplier. This enables a more complete picture of the sustainability objectives and sustainable development aims of the SC partners.

On the basis of institutional theory, the study extends current MT-SSCM concepts by including the supplier’s direct environment in the choice of ideal management practices in a particular SC setup. It provides a definition of a multi-tier SC as an institutional field and a number of research implications regarding MT-SSCM as well as generic SSCM. Moreover, the proposed framework helps SC managers to understand the complex interplay of the SC partners’ sustainability aims and provides implications for choosing the most suitable MT-SSCM practices.

Managing supply chains (SCs) for sustainability often results in conflicting demands, which can be conceptualized as sustainability tensions. This paper studies sustainability tensions in electronics SC contexts and the related management responses by applying a paradox perspective.

A single case study on the electronics SC is conducted with companies and third-party organizations as embedded units of analysis, using semi-structured interviews that are triangulated with publicly available data.

The study identifies tension elements (learning, belonging, organizing and economic performing) conflicting with general social–ecological objectives in the electronics SC. The results indicate a hierarchal structure among the sustainability tensions in SC contexts. The management responses of contextualization and resolution are assigned to the identified tensions.

Framing social–ecological objectives with their conflicting elements as paradoxical tensions enables organizations and SCs to develop better strategies for responding to complex sustainability issues in SC contexts.

The study contributes toward filling the gap on paradoxical sustainability tensions in SCs. Empirical insights are gained from different actors in the electronics SC. The level of emergence and interconnectedness of sustainability tensions in a larger SC context is explored through an outside-in perspective.

The purpose of this paper is to investigate the behavioral tendencies of supply managers when they are faced with uncertainty in making multi-tier sourcing decisions.

This paper uses the literature on multi-tier supply chains and behavioral decision making to develop a theoretical framework for examining factors influencing a supply manager’s decision to retain control over sourcing in the multi-tier context. An experimental vignette methodology is used to gather data from 259 supply managers.

Results suggest that supply managers choose to exert less multi-tier control when they have high levels of interpersonal trust in the tier-1 supplier’s sales representative. This effect is accentuated by a high level of familiarity with potential lower-tier suppliers. Under high levels of familiarity with potential lower-tier suppliers, supply managers will exert greater levels of multi-tier sourcing control as the behavioral uncertainty of the tier-1 supplier increases.

Buying firms can enhance their understanding of supply managers’ multi-tier sourcing decision making and the potential biases associated with it. Suggestions for a more effective use of multi-tier sourcing are provided in the Discussion section.

Multi-tier sourcing is an increasingly important area of research, and this paper is the first to examine individual supply managers’ behavioral decision making in the multi-tier context. This paper also contributes to the outsourcing literature by investigating behavioral factors influencing the outsourcing of sourcing activities.

A firm's ability to cascade sustainability requirements further down to lower-tier suppliers might be affected by inter-firm power relations. This study aimed to identify the power sources of focal firms and first- and lower-tier suppliers and to investigate how they may affect their ability to cascade sustainability requirements along multi-tier supply chains.

A multiple case study of 24 companies was conducted to investigate the sources of power in multi-tier supply chains. In total, 42 informants from five focal companies, ten first-tier suppliers and nine lower-tier suppliers were interviewed.

Differences were found between the sources from which focal firms and first- and lower-tier suppliers drew power. Findings revealed that firms' power sources may increase or impair their ability to cascade sustainability requirements to lower supply chain tiers. Furthermore, multi-tier supply chain-level power sources constitute a significant determinant of firms' ability to disseminate sustainability requirements to lower-tier suppliers.

The results can help companies and purchasing managers understand how their own and suppliers' power may affect their ability to cascade sustainability agendas to lower-tier suppliers. In particular, the results can be useful for supplier selection and the development of supplier relationship management strategies for fostering sustainability in multi-tier supply chains.

This study places traditional power perspectives in the context of multi-tier sustainable supply chain management, broadening the view beyond dyadic relationships that have traditionally been the focus of the supply management literature.

The purpose of this paper is to investigate how buying firms manage their lower tier sustainability management (LTSM) in their supply networks and what contextual factors influence the choice of approaches. As most of the environmental and social burden is caused in lower tiers, the authors use the iceberg analogy.

Findings from 12 case studies and 53 interviews, publicly available and internal firm data are presented. In an abductive research approach, transaction cost economics (TCE) conceptually guides the analytical iteration processes between theory and data.

This study provides eight LTSM approaches grouped into three categories: direct (holistic, product-, region-, and event-specific) indirect (multiplier-, alliance- and compliance-based) and neglect (tier-1-based). Focal firms choose between these approaches depending on the strength of observed contextual factors (stakeholder salience, structural supply network complexity, product and industry salience, past supply network incidents, socio-economic and cultural distance and lower tier supplier dependency), leading to perceived sustainability risk (PSR).

By depicting TCE’s theoretical boundaries in predicting LTSM governance modes, the theory is elevated to the supply network level of analysis. Future research should investigate LTSM at the purchasing category level of analysis to compare and contrast PSR profiles for different purchase tasks and to validate and extend the framework.

This study serves as a blueprint for the development of firms’ LTSM capabilities that suit their unique PSR profiles. It offers knowledge regarding what factors influence these profiles and presents a model that links the effectiveness of different LTSM approaches to resource intensity.

This study extends the application of TCE and adds empirically to the literature on multi-tier and sustainable supply chain management.

The purpose of this paper is to understand how supply chain actors in an Italian cashmere supply chain reacted to dependence and power use during the Covid-19 crisis and how this affected their perceptions of justice.

The research took a case study approach exploring issues of dependence, power and justice in a multi-tier luxury cashmere supply chain.

The authors found two types of dependence: Craftmanship-induced buyer dependence and Market-position-induced supplier dependence. The authors also identified four key archetypes emerging from the dynamics of dependence, power and justice during Covid-19. In the repressive archetype, buying firms perceive their suppliers as dependent and use mediated power through coercive tactics, leading the suppliers to perceive interactional, procedural and distributive injustice and use reciprocal coercive tactics against the buying firms in the form of coopetition. In the restrictive archetype, buying firms that are aware of their dependence on their suppliers use mediated power through contracts, with suppliers perceiving distributive injustice and developing ways to circumvent the brands. In the relational archetype, the awareness of craftmanship-induced buyer dependence leads buying firms to use non-mediated power through collaboration, but suppliers still do not perceive distributive justice, as there is no business security or future orders. In the resilient archetype, buying firms are aware of their own craftmanship-induced dependence and combine mediated and non-mediated power by giving the suppliers sustainable orders, which leads suppliers to perceive each justice type positively.

This paper shows how the actors in a specific supply chain react to and cope with one of the worst health crises in living memory, thereby providing advice for supply chain management in future crises.

This paper aims to investigate the bridging role of first-tier suppliers in diffusing sustainability in supply networks and how this role is facilitated by the procurement function.

The paper is based on an embedded case study of two supply networks of a coffee beans roasting company. The embedded cases focus on coffee beans and packaging supply networks.

The findings reveal less than expected involvement of the focal company and its procurement function in sustainability implementation with first-tier suppliers. Instead, sustainability diffuses upstream to lower-tier suppliers but also downstream, against the tide, as a result of the various bridging roles performed by first-tier suppliers.

This paper provides two theoretical contributions. First, it contributes to the sustainable supply network management literature by providing rich insights on sustainability diffusion to lower-tier suppliers and the role of first-tier suppliers in this process. Second, the paper contributes to structural hole theory by revealing a typology of bridging roles that actors, such as suppliers, undertake in the sustainability context.

The paper provides managers with practical insights on how sustainability can be diffused in the supply network and the different roles that first-tier suppliers can play in this direction.

This paper shows that sustainability diffusion to lower-tier suppliers is possible in the absence of focal company procurement involvement when bridging roles are undertaken by first-tier suppliers and their procurement functions are involved in the implementation process. These bridging roles facilitate sustainability diffusion both upstream and downstream.
