One of the most difficult supply network challenges facing companies today is how to diffuse sustainability not only among their direct (first-tier) suppliers but also throughout their supply networks. Although a growing body of research has been dedicated to addressing this challenge, the role of purchasing and supply management (PSM) in sustainable supply network development remains underexplored. In this paper, we present a systematic review of the literature on the role of PSM in the diffusion of sustainability in supply networks. (...) We analysed 133 peer-reviewed papers published in 21 journals in the field of PSM. We scrutinized the theories, methods and levels of analysis used in sustainable PSM research, classified the practices for diffusing sustainability in supply networks and identified the role of PSM in the diffusion of sustainability. Accordingly, we put forward a set of propositions that link diffusion practices—and the role of PSM in these practices—with embedded and peripheral sustainability and suggest future research directions.

The corporate social responsibility and industrial relations studies have evolved mostly in parallel. In this paper, we integrate the IR with the CSR perspective, highlighting their similarities and differences. In particular, the study adopts a framework which includes a wide set of CSR-related issues to explore what unions and companies negotiate under the umbrella of CSR. It analyses and compares the national sectoral agreements of two key industries in the Italian economy, i.e. Metal and Chemical. We find that these two (...) sectors exhibit differences because the CSR-related issues covered by the two contracts are formally labelled as CSR in the Chemical contract, and not labelled as CSR in the Metal contract. We also find similarities regarding the CSR-related issues covered and not covered by the national contracts, and the binding processes centrally negotiated for their implementation. We interpret the similarities in light of the specificities of the Italian IR system, and the differences in light of the negotiation traditions of the two sectors under study, which induce the actors in the Metal sector to focus more on what differentiates the CSR and IR perspectives, and the actors in the Chemical sector to focus more on what the CSR and IR perspectives share.
