Abstract: Our survey reviews the theoretical and empirical literature on all alternative policies to promote the deployment of new fiber-based communications infrastructure. Since such investment is expected to induce substantial positive externalities, dynamic efficiency becomes a particularly important policy goal. The available policies refer to i) different kinds of ex ante sector-specific regulations including cost-based access regulations as well as softer regulations such as regulatory holidays or geographically differentiated regulations, ii) deregulatory approaches based on effective competition law implementation and competitive market structures including allowance of co-investment models, and iii) public subsidies to cover non-profitable (“white”) areas. Our survey identifies the most significant research gaps, finding that numerous studies related to the impact of access regulations exist, whereas only a much smaller branch of literature addresses the impact of competition policies, and even fewer studies analyze the impact of public subsidies on new communications deployment. Moreover, our work allows for a generic framework for policy recommendations that identifies the comparative advantages of the individual policy options for different market structures and for varying degrees of externalities. We find that public subsidies are the dominant policy alternative in white areas, whereas access regulations can be the preferred policy in white or “grey” areas, where only monopoly structure or co-investment models lead to private investment. Deregulatory policies might be preferable in grey areas, if there is sufficient pressure from competitive outside options and if competition law is strong. Finally, deregulatory policies including soft regulation are the dominant policy in “black” areas, where several independent infrastructure operators exist.
