Rapidly innovating industries are not behaving the way theory expects. Conventional industrial organization theory predicts that, when parties in a supply chain have to make transaction-specific investments, the risk of opportunism will drive them away from contracts and toward vertical integration. Despite the conventional theory, however, contemporary practice is moving in the other direction. Instead of vertical integration, we observe vertical disintegration in a significant number of industries, as producers recognize that they cannot themselves maintain cutting-edge technology in every field required for the success of their products. In doing this, the parties are developing forms of contracting beyond the reach of contract theory models. In this Article, we connect the emerging contract practice to theory, learning from what has happened in the real world to frame a theoretical explanation of this cross-organizational innovation and to reconceptualize the boundaries of the firm accordingly.
