Purpose Following a negative attitude of consumers toward genetically modified organisms (GMOs) and the spaces left by the labeling legislation on GMOs of different countries, some retailers and processors introduced their own non-GMO standards, with the intention of avoiding the presence of GMOs in their products. This paper aims to understand how the implementation of these new retailer-driven standards affects governance structures along the supply chain and the determinants of such change focusing on transaction cost approach (TCA) vs resource-based view (RBV). Design/methodology/approach The non-GMO introduction is investigated as a case study in the poultry industry of France and Italy. The case relies on data primarily collected from interviews with the main actors at five stages of the supply chain from the retailer up to animal feed and crop production. Findings Findings indicate that the introduction of non-GMO products had different impacts on the transactions along the supply chain, generally leading to more integrated relationships. Theoretical relevance depends on the observed transaction and the type of governance structure considered. Interestingly, only RBV explains the shift toward hierarchical governance when this is observed. Originality/value This paper contributes to the empirical literature highlighting the upstream effects caused by the adoption of new standards. On the theoretical side, building on Conner and Prahalad’s (1996) seminal work and leveraging on the concepts of opportunism, “potential” superior knowledge and strategic importance of an activity, this research suggests a comparative framework for identifying governance structures and their determinants under TCA and RBV.
