Section 2 Symposium: Thom Lambert on Defining and Identifying Exclusionary Conduct
There’s a fundamental problem with Section 2 of the Sherman Act: nobody really knows what it means. More specifically, we don’t have a very precise definition for “exclusionary conduct,” the second element of a Section 2 claim. The classic definition from the Supreme Court’s Grinnell decision — “the willful acquisition or maintenance of [monopoly] power as distinguished from growth or development as a consequence of a superior product, business acumen, or historic accident” — provides little guidance. The same goes for vacuous statements that exclusionary conduct is something besides “competition on the merits.” Accordingly, a generalized test for exclusionary conduct has become a sort of Holy Grail for antitrust scholars and regulators.
