Joe Simons Publishes Abstract on Unilateral Effects Analysis

November 10, 2011

Litigation partner Joseph J. Simons and Malcolm B. Coate, economist at the Federal Trade Commission, co-authored an abstract to a recent paper by Gregory Werden and Luke Froeb on unilateral effects analysis with a particular focus on factors that limit the applicability of the Upward Pressure on Price (UPP) model. Werden and Froeb posit that merger simulation is well-suited for use in either screening or competitive effects analysis, a result, which if true, would marginalize the UPP model. Joe and Malcolm disagree with their observations, noting that the UPP methodology is designed to be agnostic to the underlying competitive process, and potentially applicable in a range of situations in which simulation would be infeasible. The abstract appeared on the "Antitrust & Competition Policy Blog" on November 7.
