Class Certification
Overview
Edgeworth experts are industry leaders in applying economic tools to the analysis of class certification. We have made pivotal contributions to the literature on evaluating questions of common impact and formulaic damages and have worked on precedent-setting litigation matters.
Our approach is centered on developing economic analysis that is rigorous, defensible, and can be communicated to our audience of counsel and courts in a straightforward and understandable manner. We address class certification issues across industries and practice areas, including antitrust, labor and employment, false advertising, and data privacy.
In Antitrust, Edgeworth economists work with clients in all phases of class certification—from assisting with developing the discovery record to providing expert testimony. Our experts develop economic models to consider the appropriateness of class treatment in litigation where acts of collusion or monopolization are alleged. We apply rigorous and scientific frameworks for assessing whether common evidence can be used to assess impact and damages to the proposed class, or if the economic analysis dictates the need for individualized inquiries.
In Labor and Employment, Edgeworth experts have analyzed class allegations of discrimination, wage and hours violations, and other employment-related claims. Through rigorous analyses of the industries and allegations at issue, we have testified on the commonality and typicality aspects and have critiqued liability analyses and damages models presented at the class certification phase.

Dr. Johnson concluded that determining the fact of antitrust injury for each member of the proposed class would require individualized analysis and further that a formulaic approach to damages, using class-wide evidence, would fail to provide accurate measures of harm. The plaintiffs settled with Reddy Ice’s co-defendant, Arctic Glacier, subsequent to the filing of Dr. Johnson’s report. Reddy Ice made no payment and received a full release from the plaintiffs.
