Antitrust and Competition Capabilities

Our experience in matters involving allegations of anticompetitive horizontal conduct includes cases in which plaintiffs alleged price fixing, agreements to allocate territories or customers, or group boycotts. We have worked on major cases for the joint defense and for individual clients including recent cases involving milk, credit card interchange fees, LCDs, CRTs, fuel surcharges, auto parts, and LIBOR. In these and other assignments, we have assessed the economic incentives of the alleged participants, tested hypotheses that distinguish competitive from collusive behavior, and assessed the likelihood and quantum of damages.

We have analyzed claims of monopolization, tying, exclusive dealing, and anticompetitive pricing practices, such as loyalty or volume discounts and bundled rebates. We have assessed whether these practices can be attributed to competition among firms, are the result of hard bargaining between buyers and sellers, and have efficiencies that outweigh any potential harm to competition. Our recent experience includes cases involving high-technology products, pharmaceuticals, airlines, and energy.

Cornerstone Research has worked on many direct and indirect purchaser class certification matters. Our case experience and analytical breadth enables us to meet the changing demand for rigorous empirical and conceptual assessment of both the questions of common impact and common proof and of the merits issues that bear on those questions. Recently, we have assisted counsel in matters involving mobile devices, computer components, software, automobiles, and employment practices.

We have analyzed the potential competitive effects of horizontal and vertical mergers in the context of government investigations and private litigation in the United States and Europe. We apply economic theory to define relevant markets, identify close competitors, determine competitive interactions, analyze potential price impacts and potential for foreclosure, and assess whether there are efficiencies associated with the proposed collaboration.

Cornerstone Research experts have testified on matters involving failing firm defenses and exiting assets arguments in a number of industries, including healthcare, finance, and technology. Our experts have assisted antitrust authorities in evaluating the merits of failing firm claims and consulted to merging parties arguing the failing firm defense affirmatively. Assessing failing firm arguments from both the regulatory and merging parties’ perspectives gives us distinct insight into the rigorous demands of this defense.
