In the episode of the Consumer Finance Monitor podcast released today, the host of the show, Alan Kaplinsky (founder, former leader for 25 years, and now Senior Counsel of our Consumer Financial Services Group) spoke with James Fallows Tierney, Associate Dean for Academic Affairs and Associate Professor of Law at Chicago-Kent College of Law, about his working paper, “The Value of Class Action Waivers: Evidence from Invalidation of the CFPB Arbitration Rule.” Professor Tierney’s research focuses on the intersection of law, financial markets and consumer finance. 

His study uses financial-market data to examine how investors reacted to developments affecting the enforceability of consumer arbitration agreements containing class action waivers.

Key Points Discussed:

  • An Eight-Year Project
  • Letting the Market “Speak”
  • What Did the Study Find?
  • What About Consumers?
  • Important Limitations
  • A Different Way of Looking at an Old Debate
