Antitrust And Nonexcluding Ties, Herbert J. Hovenkamp

All Faculty Scholarship

Notwithstanding hundreds of court decisions, tying arrangements remain enigmatic. Conclusions that go to either extreme, per se legality or per se illegality, invariably make simplifying assumptions that frequently do not obtain. For example, by ignoring double marginalization or tying product price cuts it becomes very easy to prove that a wide range of ties are anticompetitive. At the other extreme, by ignoring foreclosure possibilities one can readily conclude that ties are invariably benign.

Ties have historically been thought to produce two kinds of competitive harm: “leverage,” or extraction; and foreclosure, or exclusion. The two theories are not mutually exclusive. Indeed, …

Antitrust And The Costs Of Movement, Herbert J. Hovenkamp

All Faculty Scholarship

Antitrust is rightfully concerned about the structure of markets as well as the bargaining that occurs in them. As a result, the absolute cost of redeploying resources can be just as important as the transaction costs of arranging for their movement. This paper examines several broad themes in antitrust, considering the role of various assumptions about the costs of getting resources moved toward superior positions and the ability of the antitrust system to facilitate this movement. Part II very briefly examines structuralism as a theory underlying antitrust enforcement, particularly its assumptions about the difficulty and costs of moving resources. Harvard …

Antitrust And The Movement Of Technology, Herbert J. Hovenkamp

All Faculty Scholarship

Patents create strong incentives for collaborative development. For many technologies fixed costs are extremely high in relation to variable costs. A second feature of technology that encourages collaborative development is the need for interoperability or common standards. Third, in contrast to traditional commons, intellectual property commons are almost always nonrivalrous on the supply side. If ten producers all own the rights to make a product covered by a patent, each one can make as many units as it pleases without limiting the number that others can make. That might seem to be a good thing, but considered ex ante it …

Markets In Merger Analysis, Herbert J. Hovenkamp

All Faculty Scholarship

Antitrust merger policy suffers from a disconnect between its articulated concerns and the methodologies it employs. The Supreme Court has largely abandoned the field of horizontal merger analysis, leaving us with ancient decisions that have never been overruled but whose fundamental approach has been ignored or discredited. As a result the case law reflects the structuralism of a bygone era, focusing on industrial concentration and market shares, largely to the exclusion of other measures of competitive harm, including price increases. Only within the last generation has econometrics developed useful techniques for estimating the price impact of specific mergers in differentiated …
