Since the early 1980s, antitrust law has become increasingly dependent on economic theory, which is widely believed to provide the most sound basis for antitrust policy. Today, it is difficult to imagine litigating an antitrust case of any complexity without the use of one or more expert economists.1
As a result, familiarity with basic concepts in microeconomics, understanding the appropriate parameters of economic expert testimony, and fitting the facts of a case into a broader economic narrative have become core competencies for the antitrust litigator.
