Class Certification

Class certification plays a critical role in complex litigation by determining whether claims can proceed on behalf of a proposed class. Econ One delivers economic analysis, expert testimony, and strategic consulting to class certification matters involving antitrust, consumer protection, securities, employment, product liability, environmental, privacy, and other complex litigation. Our experts evaluate class-wide economic issues using rigorous economic analysis, statistical methods, and econometric modeling to assess common impact, economic injury, damages, and other issues central to class certification. We develop objective, defensible analyses that support class certification, merits, liability, and damages proceedings before courts, arbitrators, and regulatory agencies across a broad range of industries. Our team has advised clients on both direct and indirect purchaser matters, from early case assessment through expert testimony.
