1 Flynn, John J.Antitrust jurisprudence: a symposium on the economic, political and social goals of antitrust policyFelix S. Cohen has observed that [a]n ethics, like a metaphysics, is no more certain and no less dangerous because it is unconsciously held. There are few judges, psychoanalysts, or economists today who do not begin a consideration of their typical problems with some formula designed to cause all m...Efficiency; Analysis ; Assumptions1977
