The purpose of this paper is to identify factors that constrain marketing choices available to smallholders, limiting the chain's robustness from their perspective.

This paper draws on transaction cost economics to develop a model explaining dyadic relationships between smallholders and their buyers. The model was used to analyse a case study of the supply chain for organic fresh vegetables in Kathmandu, Nepal.

This chain is characterised mainly by relational contracting between smallholders and their buyers. There was also evidence of vertical integration by some buyers, and of growers selling on informal markets. However, there was no evidence of spot market trading or of conventional contracting. These outcomes were attributed primarily to the absence effective standards and legal systems. Despite this, the chain offered smallholders a range of dyads with different risk-reward trade-offs.

This paper is based on the findings of a case study. While the results can be generalised to theory, they cannot be generalised to other supply chains.

This study considers supply-chain performance from the perspective of smallholders. The model proposed for the study extends the traditional vertical coordination continuum to incorporate missing dyads and informal markets.

The purpose of this paper is first, to develop constructs to measure three important concepts in the supply chain literature: contracts, trust and market environment, in the Chinese context and to further investigate the relationships amongst these three concepts based on the formulated hypothesis.

The research methodology has strictly followed the recommended scale development procedures, which include specifying each constructs, item generation, data collection, reliability and validity test, and finally test hypothesis. The primary data were collected in October 2008 in Hubei Province, China. Both exploratory factor analysis and confirmatory factor analysis are applied to assess the reliability and validity of the three constructs.

In total, 22 items were retained to measure six dimensions for the three core concepts: contract (marketing and production), trust (reliability and benevolence), and market environments (diversity and volatility). Second, the finding supported this argument that contracts and trust functions as complements. Furthermore, a positive relationship between environmental uncertainty and the use of contractual governance was found.

The measurement model for environmental volatility is less satisfied. More research should be carried out on the measurement of market environment in the future.

This paper identifies and validates key constructs underlying supply chain management research: contract, trust and market environment, in a Chinese context. These measurable concepts could be applied in similar settings to further investigate small‐scale farmer's position along the supply chain.

This paper aims to clarify ambiguous results from previous research on the relationship between contextual factors, trust and supply chain governance (SCG).

This study carried out a systematic literature review in 11 databases, with articles published until 2018. Afterward, this study conducted a thematic analysis in 60 articles to address the contextual factors, governance structures and trust approaches raised in previous research.

The thematic analysis revealed that seven contextual factors influence the choice of contractual and relational mechanisms in supply chains: relationship history, environmental uncertainty, perceived risk, perceived justice, asset specificity, power asymmetry and interdependence. The findings explained the ambiguous results of past research by proposing that contractual and relational governance are complementary and that the presence of trust (affective and competence-based) moderates the relationship between contextual factors and SCG.

This research advances the SCG literature by proposing trust (affective and competence-based) as a moderating variable that fosters governance mechanisms in supply chain relationships.

The purpose of this paper is to analyze the influence of chain governance on chain performance among the chain members.

The survey was conducted in a triadic context with 345 chain members (115 dairy farmers, 115 dairy cooperative managers, and 115 processors) of the dairy sector in Uganda. Data collection was performed through simple random sampling by survey questionnaires with the chain executives. SEM was used for data analysis.

The results revealed several chain governance structures (spot market, relational, contractual and mini integration) confirmed the hypothesized correlations on chain performance at different chain levels. The authors found a positive influence of relational governance on chain performance for all the chain members; however, the effect is stronger at the first supplier chain level.

This triadic chain approach makes an original contribution to the chain governance structures and chain performance literature in the supply chain context. Studies analyzing all aspects of chain governance structure and chain performance at three chain levels are limited.

This paper identifies, evaluates and structures research that focuses on “collaboration” (C), “trust” (T) and “performance” (P) in the agri-food supply chain (AFSC) and reveals its intellectual foundation. It aims to synthesize research published over a period of 18 years (from 2003 to the beginning of 2020) and provide a platform for practitioners and researchers in their efforts to identify the existing state of work, gaps in current research and future directions in the area of collaboration–trust–performance (CTP) in the AFSC.

Prior to carrying out a bibliometric analysis (BA), literature search was performed, identifying 69 related papers focused on CTP in the AFSC. The content of the papers was further analysed in a systematic literature review (SLR) with regard to the subject area, theoretical lenses, research methodology, supply chain (SC) category and other relevant categories.

CTP in the AFSC are based on a relationship marketing and operations management fundament but show specific particularities. AFSCM is a multi-dimensional design task, and collaboration is considered a necessity, whereas trust significantly affects the AFSC effectiveness. The paper also develops a conceptual CTP model, which shows the interrelations between all identified construct variables, where the authors were able to see also bi-directional relations. Furthermore, the paper presents viable future research opportunities, e.g. focus on organic food chains or multi-actor analysis.

Results of the conducted BA refer to the CTP discussion within a preselected number of peer-reviewed academic articles, which are provided by the WoS CC (Web of Science Core Collection) database.

CTP measurements within the AFSC context are a relevant subject with increasing academic interest in the area of agricultural economics as well as operations and supply chain management (SCM). Therefore, further studies are necessary to develop the related theory and ascertain the practical implications of collaboration, trust and performance among members in the consistently complex AFSC.

CTP have been recognized as important factors for designing a sustainable SCM strategy, particularly in the case of the AFSC. However, although previous studies have addressed the AFSC, there is insufficient knowledge regarding all three pillars (CTP) and how they enable successful AFSCM. The originality of this paper lies in systematically mapping the intellectual base of CTP research and providing path forward for research in AFSCM.
