The problems are difficult, and the law is not likely to meet them directly. [We do not] mean to suggest that the law must alone move within the confines of changing fashions in such theory. The law indeed can have a life of its own. But in this field of law more than any other, the general presumptions are of such a character that they cannot be readily isolated from the corresponding presumptions which dominate economic theory. We do suggest that in the future there may well be a recognition of the instability of the assumed foundation for some major antitrust doctrines. And this may lead to a re-evaluation of the scope and function of the antitrust laws. (p. 296) In this prescient final paragraph, Director and Levi laid a foundational neoliberal premise, which would develop into a more extreme form in the coming years: Antitrust law should utilize economic theory, and Director and Levi had in mind the special brand of economic theory they espoused-not the versions of imperfect competition theory espoused by the Cowles Commission or MIT (Mirowski 2002).
