Guest editorial. Theorizing economic plurality and making it mainstream is crucial

The present issue of the Journal of Co-operative Studies features three papers selected from the Lyon ICA Conference. All three discuss the specific contributions of cooperatives in the context of organizational plurality. Under a theoretical viewpoint, Chevallier focuses on cooperative (in)efficiencies as they are analyzed (or not) in economics, while Borzaga, Depedri and Tortia discuss theories able to properly analyze the specific role of cooperatives and social enterprises as well. Under the empirics of evidence, Gloukoviezoff analyzes the remaining specificities of French financial cooperatives concerning financial inclusion.
