Abstract

When it comes to finding whether a firm has violated antitrust law, economists are often called upon as expert witnesses by the parties involved in litigation.
This paper focuses on a challenge that economists may face when appearing as expert witnesses in US federal courts, namely to comply with the so-called Daubert standard of admissibility of expert testimony. I propose a new
framework for analysing the interplay between model applicability and admissibility standard in courtrooms. The framework distinguishes between weak applicability claims, stating that a model’s critical assumptions are shared by the
target, and strong applicability claims, connecting empirical models and specific market features. I use this distinction to examine a recent antitrust case where an expert testimony based on economic models has been assessed following the
Daubert standard.
