Regulations governing broadband networks are being considered. Natural experiments conducted with respect to "open access" rules yield probative marketplace evidence. Using the metric of subscribership, policy regimes are compared. Prior to 1Q2003, cable modem service was unregulated (and has...

Alfred Kahn's book, Letting Go: Deregulating the Process of Deregulation, suggested that regulators step aside once they have set basic rules for entry into erstwhile monopolized markets. Unfortunately, communications regulators have not heeded Professor Kahn's advice. I provide an analysis of...
