Purpose – The aim of this paper is to analyze which sustainable supply chain management (SSCM) arguments are addressed in the base of the pyramid (BoP)-related research. BoP projects address how companies contribute to fulfilling the needs of the poorest populations; increasingly, academics are applying theory to explain these projects. The need for integrating the BoP population into value-adding activities is widely acknowledged, but this is not yet reflected in supply chain management (SCM)-related concepts. The links to SSCM are frequently mentioned but in a scattered manner. Design/methodology/approach – The paper presents a structured literature review of BoP papers published between 2000 and 2014 in peer-reviewed, English-speaking journals available on Web of Science. A content analysis of BoP papers is conducted based on SSCM constructs from the framework presented by Beske and Seuring (2014). Findings – The frequencies of SSCM constructs identified in the BoP papers indicate the prevalence of SSCM arguments in the BoP discourse. Technological integration emerges as the core SSCM practice frequently identified and is contingent with a number of other practices. Further, SSCM practices including long-term relationship development, partner development, joint development, enhanced communication, learning, stakeholder management and innovation have regularly been referred to and are considered important by respective BoP scholars. The contingency analysis shows significant correlations among various pairs of categories and allows us to point to major lines of related arguments. Research limitations/implications – The paper offers insights into the potential links between the SSCM and BoP research streams and sets ground for further theoretical exploration of the subject. Limitations are the uptake of one particular conceptual framework, the selection of BoP papers for the review process and the interpretation of the frequency and contingency analysis. The paper offers a foundation for developing a research stream where BoP-related issues are integrated into research on (S)SCM. Practical implications – SCM has many practical applications, which help to establish and improve supply chain design and operations. This would benefit BoP projects and should improve their practical outcomes. The relevance of technological integration seems straightforward, but needs a lot of effort to be implemented in each single project. Social implications – BoP-related research has gained increasing attention in recent years and should help drive the global sustainable development agenda further in the respective geographic locations. Establishing capable supply chains that deliver sustainable outcomes will be at the core of such projects. This paper highlights fundamental practices for firms targeting BoP markets with an effort to alleviate poverty. Originality/value – The paper applies SSCM theory to analyze BoP issues and thereby interlinks the two research streams. Until now, research amalgamating the two concepts has been disconnected. Therefore, by providing an overview of existing publications, more focus for future studies is created, which is valuable and necessary for advancing both fields. Additionally, assessing BoP-type projects in low-income countries will allow the SSCM agenda to look beyond what is so far typically researched.

PurposeLiterature review articles have become a frequently applied research approach in operations and supply chain management (SCM). The purpose of this paper aims to elaborate on four approaches for developing or employing theory in systematic literature reviews (SLRs).Design/methodology/approachThe paper uses conceptual arguments and illustrates them by pointing to recent examples. In SLRs, the material collection is usually based on keywords and searching databases, which is comparatively well documented. Data analysis, however, often falls short in documentation and, consequently, is neither well explained nor replicable. Therefore, the focus of this paper is the elaboration of the data analysis and sense-making stage in the research process of SLRs.FindingsThe paper presents four different approaches, which are characterized as theory (1) building, (2) modification, (3) refinement and (4) extension, based on whether new concepts are formed or extant concepts within SCM or other fields of management theory are adopted.Research limitations/implicationsThe limitation of this research is that literature reviews could be conducted and presented in many ways. Since the focus of this research is on systematic literature reviews, only a limited number of approaches can be discussed and presented here.Originality/valueThe paper contributes to explaining the process and expected outcomes of a literature review and, therefore, aids in further developing the related methodological approaches. This is relevant as literature review publications now often replace conceptual or theoretical pieces but still have to deliver concerning demands of theory building.

PurposeBase-of-the-pyramid (BoP) markets are frequently characterized by institutional voids. However, it remains unclear how institutional voids impact corporate and supply chain risk and performance. This intersection will be analyzed in this paper.Design/methodology/approachThis paper presents a systematic literature review of 94 BoP papers published between 2004 and 2019 in peer-reviewed, English-language journals available on Scopus. Drawing upon established frameworks for examining institutional voids, supply chain risks and BoP performance, frequency, and contingency analyses are conducted. Contingencies are established to provide insights into the associations between different constructs from the selected frameworks.FindingsSupply chain risks are pervasive in the BoP discourse, especially when BoP markets are characterized by institutional voids. The frequency analysis of the constructs suggests that the key supply chain risks discussed in the BoP literature include social risk, credit risk, product market and operating uncertainties, knowledge and skill biases and decision-maker risks due to bounded rationality. The contingency analysis suggests that institutional voids are associated with supply chain risks that affect performance.Research limitations/implicationsA theoretical framework aligning three research streams in the context of BoP calls for future studies to test the causality of highlighted constructs that are significantly associated. The analysis is confined to the constructs that are taken into account based on specific conceptual frameworks.Practical implicationsThe study provides practitioners with a framework to manage supply chain risks in BoP-related firms to enhance firm performance. Managers can use key dimensions of supply chain risk, such as the product market, the input market and operating uncertainties, to evaluate performance in the BoP context.Originality/valueSpecifically, this research has strengthened the inquiry of supply chain risks in the presence of institutional voids that may have an impact on firm performance
