Our purpose in this paper is to identify some of the implications that derive from the incompleteness of antitrust laws. Since with regard to certain anticompetitive conduct, the law remains substantially incomplete up to the first relevant court judgment, in terms of policy it is worth concentrating on stand-alone claimants who, not relying on earlier judgments, face very high evidentiary requirements, while generating large positive (information) externalities for potential follow-on claimants. The paper is structured as follows. In Sect. 2, we introduce the notion of incompleteness of the laws and address the process of production of evidence in antitrust lawsuits. Sect. 3 provides a survey of EU national case law and our summary of the results puts emphasis on incomplete laws, evidentiary requirements and stand-alone lawsuits. Sect. 4 presents a framework model to distinguish the decision-making processes for stand-alone and follow-on claimants in the presence of incomplete antitrust laws. In Sect. 5 we introduce a vector autoregressive model that we test with reference to the US antitrust law enforcement regime. Sect. 6 discusses some policy options and concludes the paper.
