After thirty years, the debate over antitrust's ideology has quieted. Most now agree that the protection of consumer welfare should be the only goal of antitrust laws. Execution, however, is another matter. The rules of antitrust remain unfocused, insufficiently precise, and excessively complex. The problem of poorly designed rules is severe, because in the short run rules weigh much more heavily than principles. At bottom, antitrust is a defensible enterprise only if it can make the microeconomy work better, after accounting for the considerable costs of operating the system.

The Antitrust Enterprise is the first authoritative and compact exposition of antitrust law since Robert Bork's classic The Antitrust Paradox was published more than thirty years ago. It confronts not only the problems of poorly designed, overly complex, and inconsistent antitrust rules but also the current disarray of antitrust's rule of reason, offering a coherent and workable set of solutions. The result is an antitrust policy that is faithful to the consumer welfare principle but that is also more readily manageable by the federal courts and other antitrust tribunals.

In this integration of law and economic ideas, Herbert Hovenkamp charts the evolution of the legal framework that regulated American business enterprise from the time of Andrew Jackson through the first New Deal. He reveals the interdependent relationship between economic theory and law that existed in these decades of headlong growth and examines how this relationship shaped both the modern business corporation and substantive due process. Classical economic theory—the cluster of ideas about free markets—became the guiding model for the structure and function of both private and public law.

Hovenkamp explores the relationship of classical economic ideas to law in six broad areas related to enterprise in the nineteenth and early twentieth centuries. He traces the development of the early business corporation and maps the rise of regulated industry from the first charter-based utilities to the railroads. He argues that free market political economy provided the intellectual background for constitutional theory and helped define the limits of state and federal regulation of business behavior. The book also illustrates the unique American perspective on political economy reflected in the famous doctrine of substantive due process. Finally, Hovenkamp demonstrates the influence of economic theory on labor law and gives us a reexamination of the antitrust movement, the most explicit intersection of law and economics before the New Deal.

Legal, economic, and intellectual historians and political scientists will welcome these trenchant insights on an influential period in American constitutional and corporate history.
