Weyerhaeuser And The Search For Antitrust's Holy Grail, Thom Lambert

Faculty Publications

A general definition of exclusionary conduct has become a sort of Holy Grail for antitrust scholars. At present, four proposed definitions appear most promising: (1) conduct that could exclude an equally efficient rival; (2) conduct that raises rivals' costs unjustifiably; (3) conduct that, on balance, impairs consumer welfare by creating market power without providing countervailing consumer benefits; and (4) conduct that makes no economic sense but for its exclusionary effect on rivals.
