Wolfgang Briglauer, Carlo Cambini, Klaus Gugler, and Volker Stocker conducted the study Net neutrality and high-speed broadband networks: evidence from OECD countries. They offer an investigation of the impact of net neutrality rules to investment in fixed line, high speed broadband networks from 2000-2021 years in 32 countries. Using various panel estimation techniques, including instrumental variables estimation, they find empirical evidence that net neutrality regulations exert a significant negative impact on fiber investments. They conclude that so-called hard net neutrality regulations slow down the deployment of new fiber-based broadband connections.
