A corporation and a cooperative are distinguished by the single origin constraint. The single origin constraint entails that the product requiring the inputs of the members of a cooperative will never be divested. It is es-tablished that a concentric diversification strategy results in randomly distributed clusters of related products of the product portfolio of corporations, while the single origin constraint of a cooperative is responsible for pulling all prod-ucts together in one cluster. More general, the centripetal effect of one product with infinite lifetime on portfolio com-position dominates the centrifugal effect of products with finite lifetime, regardless the number of products with finite lifetime.
