We attempt to combine the concept of assets with S-D logic to propose a new concept—cooperative assets. We submit that cooperative assets differ from customer assets or customer equity in at least three important aspects. First, cooperative assets emphasize that the value of non-transactional behavior is as important as that of transactional behavior. Second, assets are created through the interaction between firms and customers, that is, value is co-created by both actors, not supplied by one to the other. Finally, the value of cooperative assets is bilateral, i.e., value is shared between both firms and customers.
