For example, a capital-intensive firm might agree with a union to impose higher wages in the industry, to the disadvantage of labor-intensive rivals. The concept of raising rivals' costs was developed more thoroughly in the 1980s in a series of articles by Jaunusz A. Ordover, Garth Saloner, Steven C. Salop, David T. Scheffman

The concept of raising rivals' costs has been the basis for finding an antitrust violation in such rebate-bundling cases as LePage's, Inc. v. 3M and SmithKline Corp. v. Eli Lilly & Co. In those cases, the defendants adopted rebate systems over their broad range of products such that, to match the net dollar value of the rebates to purchasers, the plaintiffs' competitors with narrower product ranges had either to provide a much greater unit rebate on their sales or else exit the business.

Historical development

In two articles in the mid-1980s, Steven Salop and David Scheffman argued that a dominant firm could profit from raising rivals' variable costs if the increase in costs led to a sufficient increase in the dominant firm's demand that exceeded the shift in its average cost curve. They contended that raising rivals' costs are more advantageous competitively than predatory price cutting, particularly when the firm's "direct costs of a cost-raising strategy may be far lower than the costs inflicted on the rivals." More recently, Scheffman explained that it will be profitable to raise rivals' costs if "the dominant firm can raise the market price at the current level of output by more than the firm raises its average cost (keeping output constant)."

Since then, a considerable body of economic literature and some caselaw accumulated. But it was inconclusive. Scheffman concludes:

The important lesson that was largely ignored, at least in the ensuing economics literature, was that lawyers and the judicial system could not be convinced that economics could suitably draw the line determining when a firm with market power was doing "too much" of what are otherwise normal competitive strategies and tactics, particularly with respect to product innovation and introduction, expansion, and pricing. The subsequent literature has not contributed much to drawing that line credibly.
