Antitrust and Competition Cornerstone Research provides economic analysis
for litigation and regulatory matters involving proposed mergers and allegations
of anticompetitive horizontal conduct or monopolization. We have worked on
class certification, liability, and damages in a range of industries, including
technology, financial institutions, agriculture, telecommunications, and
pharmaceuticals. Our staff and experts also have experience with cases at the
intersection of antitrust with intellectual property and involving labor and
financial markets.
PRACTICE DETAILS
Price Fixing and Horizontal Conduct
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.

Monopolization and Exclusionary Practices
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.

Mergers and Acquisitions

3. 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.
