Research efforts aiming to improve understanding of how various organisational relationships contribute to better food quality (FQ) in a constantly changing business environment are limited. This study examines the effects of supply chain (SC) organisations on the quality of food products across multi-tiered segments with dynamic business situations.

Guided by a conceptual research framework based on contingency theory and netchain analysis, moderation-based partial least squares structural equation modelling (PLS-SEM) was used to analyse multi-tiered data from 405 shrimpers and 238 women processors in Akwa-Ibom, Lagos and Ondo states in Nigeria.

The authors' findings show that unpredictable business environments such as market turbulence (MT), power asymmetry (PA) and distrust (DT) not only directly influence SC organisations but also moderate how organisational networks contribute to improved FQ. Further results reveal that closer vertical ties such as relational contracts are prerequisites for small-scale actors to guarantee improved FQ along multiple nodes of the food system.

This is the first study to examine, from a contingency and multi-tiered perspective, how small-scale actors can maintain FQ across interdependent nodes of a food chain in a developing country context and to explore the complex interplay between SC networks and the quality of highly perishable food products in unpredictable business environments. Relevant theoretical and policy implications are discussed.

Much has been written on the effect of fast-moving business environments on organizational and supply chain (SC) management. Yet, empirical findings on the effect of changing external and internal contingencies on today’s globalized agrifood SC networks and performance are still fragmented into different organizational instruments, with some conflicting results remaining unexplained. This study aims to address these deficiencies by providing a comprehensive research framework to investigate how SC external and internal contingencies jointly influence organizational SC network structures and agrifood performance across mutually dependent tiers.

Using partial least squares structural equation modeling, the so-called “contingency–netchain–performance” framework, based on contingent resource-based theory and the netchain approach, was empirically tested on data obtained from a standardized survey of 405 artisanal producers and 238 processors in the Nigerian shrimp sector.

The results provide statistical evidence that supports the path dependency of firm performance from the interplay of vertical, horizontal and lateral relationships and, primordially, from both external and internal contingencies. The findings show that the contingency paradigm of fit among small-scale food producers and processors cuts across tiers and uncover a tendency to adopt relational governance and tighter network structures that result in an organic organization as the best-fitting structure.

The paper presents a new research framework that offers comprehensive empirical explanations for the joint influence of SC external and internal contingencies on organizational SC network structures and performance across mutually dependent agrifood tiers. This study’s conceptual, practical and policy implications for SC management provide a nascent and flexible basis on which to identify the best-fitting organizational strategies that maximize firm performance across agrifood SC tiers characterized by changing business environments.

Effective and flexible organizational models have become an avenue for driving smallholder competitiveness in the agricultural sector. However, little is understood about the processes by which resource-constrained actors deploy their organizational networks to generate and retain value in rapidly changing agrifood environments. This study examines the moderating effects of business contingencies on the interplay between organizational relationships and the resource-based performance of small-scale farmers in a developing country.

The authors propose a novel conceptual framework grounded in the relational view, netchain and contingency theories. Cross-sectional data obtained from 330 maize farmers in rural Zambia were analyzed using variance-based structural equation modeling, which involves mediation-moderation analysis.

The results show that all relational networks – vertical, horizontal and lateral – positively mediate the effects farm resources and social capital have on farmers' performance. However, these effects change depending on the predominant agency situations. Specifically, asymmetric power from customers and reputable competitors weakens the positive effect of closer horizontal relationships on business performance, while the positive effect of tighter informal vertical relationships on farmers' performance weakens under conditions of high affective trust. Moreover, the gender-based multigroup analyses highlight variations in the contingent relational view of men- and women-headed households.

The study relies on cross-sectional data from one agribusiness sector in Zambia, thus generalizations should be cautious.

The uniqueness of this study lies in the proposed theoretical framework and new empirical insights, which extend the scope of the relational view to small-scale farming households in developing countries.
