Price Dispersion and Class Certification in Antitrust Cases: An Economic Analysis

Posted by D. Daniel Sokol

James F. Nieberding (LECG) and Robin Cantor (Navigant Consulting) tackle the issue of price dispersion in antitrust litigations in their article Price Dispersion and Class Certification in Antitrust Cases: An Economic Analysis.

ABSTRACT: Differences in prices paid by putative class members (?price dispersion?) often become a focal point for class certification in antitrust matters. This paper discusses how an economic analysis of the existence, extent, and nature of price dispersion faced by plaintiffs seeking class certification may be informative even in matters thought to be particularly appropriate for class treatment (e.g., horizontal price-fixing). The existence of price variability among the products at issue can be addressed within the class framework if such price differences are systematic and able to be controlled for in any ?but-for? pricing analysis.
