We correct and clarify the results of Gans (J Regul Econ 47:183–200, 2015) regarding the effects of net neutrality regulation on equilibrium outcomes in settings where a content provider sells its services to consumers for a fee. We examine both pricing and investment effects. We extend the earlier paper’s result that weak forms of net neutrality are ineffective and also show that even a strong form of net neutrality may be ineffective. In addition, we demonstrate that, when strong net neutrality does affect the equilibrium outcome, it may harm efficiency by distorting both ISP and content provider investment and service-quality choices.
