Rigorous Analysis of Class Certification Comes of Age

Antitrust Law Journal

President and CEO of Edgeworth Economics, Dr. John H. Johnson and Dr. Gregory Leonard discuss the empirical analyses used to determine class certification issues in Rigorous Analysis of Class Certification Comes of Age, published by the ABA’s Antitrust Law Journal. In their second article on the topic, the authors demonstrate the continued value of econometric methodologies in assessing issues of commonality. Using the treatment effects literature from econometrics, Dr. Johnson and Dr. Leonard evaluate ‘common’ approaches to modeling but-for prices, providing testable implications along the way.
