The Obama Administration's Council of Economic Advisers expressed concern that competition was threatened by increasing industry concentration. Academics, commentators, and journalists have joined the chorus. But none demonstrated increasing concentration of meaningful markets, as are used in...

This paper explains how basic microeconomics can be used to assess lost profits from patent infringement. The main suggested analysis is an adaptation of merger simulation. Observed prices and quantities are combined with estimated demand parameters to calibrate a model of the industry with...

Owners of standard essential patents (SEPs) are cast as villains for engaging in “patent hold-up,” i.e., taking advantage of the fact that they negotiate royalties with implementer-licensees that already have made sunk investments in the standard. In contrast to “patent ambush,” patent...

In the competitive analysis of mergers, "calibrated economic models" are standard, formal models, particularly monopoly and oligopoly models, in which the values of the key parameters are set on the basis of observable features of the industry under review. Calibrated economic models offer three...

Eager to shed constraints imposed by Sherman Act precedent, New FTC Chair Lina M. Khan issued a statement declaring her intention to attack “unfair methods of competition even if they do not violate a separate antitrust statute.” She has sought to distance herself from the Sherman Act’s...

This chapter first reviews the economic theory underlying the unilateral competitive effects of mergers, focusing on the Cournot model, commonly applied to homogeneous products; the Bertrand model, commonly applied to differentiated consumer products; and models of auctions and bargaining,...

Licensing technology essential to a standard can present a hold-up problem. After designing new products incorporating a standard, a manufacturer could be confronted by an innovator asserting patent rights to essential technology. A damages remedy provided by antitrust or some other body of law...

A raft of articles offered contrasting views on analytic tools for assessing unilateral effects from differentiated products mergers. We revisit this debate to clarify the issues and place them in context. We consider the choice among analytic tools at three stages of a merger assessment -...

Scholarship on competition policy has begun to explore the implications of learning from behavioral research and to challenge the assumption of profit maximization at the heart of neoclassical economic theory of the firm. This scholarship is briefly reviewed, focusing on merger control....
