As the business practice that most directly raises these kinds of questions, predatory pricing is at the core of antitrust debates. The history of its law and economics offers a privileged standpoint for assessing the broader development of antitrust, its past, present and future. In contrast to existing literature, this book adopts the perspective of the history of economic thought to tell this history, covering a period from the late 1880s to present times.

The image of a big firm, such as Rockefeller’s Standard Oil or Duke’s American Tobacco, crushing its small rivals by underselling them is iconic in American antitrust culture. It is no surprise that the most brilliant legal and economic minds of the last 130 years have been engaged in solving the predatory pricing puzzle. The book shows economic theories that build rigorous stories explaining when predatory pricing may be rational, what welfare harm it may cause and how the law may fight it. Among these narratives, a special place belongs to the Chicago story, according to which predatory pricing is never profitable and every low price is always a good price.
