Whereas the U.S. recently reversed its regulations, thus returning to a less strict regime, the EU has maintained its course and recently revised implementation guidelines for its strict and rather interventionist net neutrality regulations. To this day, there exist only a few U.S.-focused empirical investigations on the impact of network neutrality regulations, based on rather broad measures of investment activities. Our paper provides the first estimation results on the causal impact of net neutrality regulations on new high-speed (fiber-optic cable-based) infrastructure investment by Internet service providers (ISPs) and on related consumer subscription to fiber-based broadband connection services. We use a comprehensive OECD panel data set for 32 countries for the period from 2003 to 2019 and various panel estimation techniques, including instrumental variables estimation.
