Description
A damages model that fails to measure damages according to the actual theory of liability is precluded, but plaintiffs still need to put forth a model that weeds out the injured from uninjured class members at the certification stage.
Further complicating the picture--as courts grapple with issues of injury, aggregate proof, standing, and the distinct legal requirements of different legal claims--are the variety of methods proposed to calculate damages. These include surveys, choice-based conjoint analysis, repair cost methods, full refund, hedonic regressions, and others. Some use different forms of regression analysis and inferential statistics.
Challenges to these damages models typically arise at the certification stage. Counsel for both plaintiffs and defendants need to understand these damages models and how to use expert witnesses to testify about the plaintiffs' damages calculations and how to attack the plaintiffs' damages models.
Listen as our panel reviews the legal and economic landscape and what it means in practice for there to be a nexus between the theory of harm and the damages model. The panel will analyze the different classwide damages models and explain the effective use of expert witnesses to prove or attack the plaintiffs' damages model.
