Stakeholder theory may be the Archimedes lever that allows defining a possible Economy for the Common Good; however, the theory’s current level of development does not enable it to escape the criticism that considers it nothing more than shared egoism. The expansion of the concept of stakeholder, including not only groups that collaborate in the creation of value or which are actively impacted by the organisation, but also incorporating those affected by omission – non-stakeholders – would lead to the reconciliation of stakeholder theory and the common good. Nevertheless, to set it within corporate practice, besides having selfish and altruist incentives, would be of interest for the conceptual development of shapeholders, understood as the link between non-stakeholders’ interests and needs, and firms.
