Keith N. Hylton (Boston University - School of Law) has posted Unilateral Refusals to Deal and the Antitrust Modernization Commission Report (Antitrust Bulletin, Forthcoming) on SSRN. Here is the abstract:
The Antitrust Modernization Commission recommends that refusals to deal with rivals in the same market should rarely, if ever, be unlawful. I will focus on the principles that should determine the legal standard governing unilateral refusals to deal. A legal test that is strongly biased in favor of defendants, as the Commission recommends, is desirable as a default rule and especially in cases in which the essential facility at the core of the refusal to deal dispute is efficiency enhancing. However, there is another set of cases in which the defendant gains control of an essential market portal. In these cases, a legal test that is less biased toward defendants may be preferable to the Commission's suggested approach.
