Platforms, systems competition, and innovation: Reassessing the foundations of communications policy

Focusing on the effects of policy on investment and innovation this paper examines whether the conceptual foundations of sector regulation are aligned with the current technological and economic conditions of advanced communications. One conclusion is that the prevailing theories and practices are only adequate if the policy challenge can be reasonably approximated as a static or steady-state problem but they may have serious shortcomings if this is not possible. The article proceeds with a review and critical examination of two approaches that could augment or possibly replace the traditional approach under conditions of dynamic competition-the theory of platform markets and systems approaches. Both frameworks model aspects of competition in interconnected systems in more detail and offer novel insights to inform communications policy in an era of continuous change. Nonetheless, important theoretical and implementation gaps remain that will require additional efforts by researchers and practitioners.
