Theory of Competition
Herbert Hovenkamp*
Since 1890, scholars have debated the relationship between the
Sherman Act and the common law of trade restraints. Did the framers
merely intend to enact the common law, or did they hope to do something
more? Was there an identifiable common law, or was it simply an
artificial construct?' This Essay examines the relationship between com-
mon law, economics, and political theory at the time the Sherman Act was
passed. It argues that the great difficulty we have had in understanding the
relationship between the Sherman Act and the common law lies in the fact
that in 1890 the common law of competition was itself undergoing a
revolution-the same revolution that political economy experienced as
classicism was supplanted by neoclassicism.2
One of the great myths about American antitrust policy is that courts
first began to adopt an economic approach to antitrust problems in the
relatively recent past3-perhaps as recently as the late 1970s.4 At most, this
revolution in antitrust policy represented a change in economic models.5
Since its inception, antitrust policy has been forged by economic ideology.
But even the common law experienced economic revolutions. The
notion of some,6 that antitrust can be freed of involvement in economic
policymaking if we can only rediscover its common-law roots, is based on a
misconception. The misconception is that the common law itself was
somehow exempt from economic policymaking. It never was exempt, in
any branch, and certainly not in the law of monopolies and restraints on
trade. The common law responded dramatically to the death of mercantil-
ism and the rise of classicism in the late eighteenth century.7 It responded
equally as classicism collapsed a century later.
Courts realized this at the time the Sherman Act was passed, as they
wrestled with the problem of how much economic analysis was appropriate
in judge-made antitrust policy. Judges preferred the relatively traditional
