The standard governance theories predict the failure of cooperatives. User-owned, user-controlled and user-benefited organisations, cooperatives possess a unique ownership structure which makes them susceptible to face various governance problems according to the property-rights and agency theories. Paradoxically, cooperatives are not a marginal phenomenon worldwide. They are long-lasting, resilient to crises organisations, in particular in the agricultural sector. This observation suggests some weaknesses in the classical conceptualisation of cooperatives’ governance and performance. Based on a meta-analysis, a systematic literature review and a stochastic production     frontier approaches, our results show that several dimensions of this organisational form deserve more academic attention. The understudied macro-institutional environment, including the existence of a federative network, shapes the effects of cooperatives on their members. Understanding how members collectively build sustainable institutional arrangements calls for an equal consideration of the economic and democratic dimensions of the cooperative through alternative theoretical frameworks. These approaches allow for better understanding of the members’ ability to overcome and take advantage of institutional and group constrains such as member heterogeneity.
