Abstract

The essay describes the most meaningful recent decisions of the Supreme Court of the United States and of lower courts on single brand aftermarkets for replacement parts and services, putting into historical context the market economics that inspires current antitrust jurisprudence. Particularly, it shows that the post-classical approach has never entirely superceded neo-classical doctrines. Rather, several shifting tides of theory have swept, and still sweep, over the domain of antitrust doctrine influencing the debate unevenly.
