A Further Review of the Internet Association's Empirical Study on Network Neutrality and Investment

In a recent perspective, I reviewed a report authored by Dr. Christopher Hooton of the Internet Association on the impact of Net Neutrality regulation on broadband infrastructure investment. My earlier review of the IA Report focused mainly on Dr. Hooton’s difference-indifferences (“DiD”) model, which from an empirical perspective is the only analysis he offered that could plausibly quantify the effects of the regulation since it involves a counterfactual.

In this perspective, I return to Dr. Hooton’s analysis. My interest in further analysis stems from Dr. Hooton’s claim that his evidence leans in the direction of a positive investment effect in that his “regression coefficients of interest were positive in all but one case.” (That negative case being his primary DiD analysis.) Closer inspection of these “positive” cases reveals errors as severe, if not worse than, the errors plaguing his DiD analysis, including the fabrication of much of his data.
