Antitrust Law and Economics

ISBN: 978-0-76231-115-6, eISBN: 978-1-84950-278-8

Publication date: 1 July 2004


This is the first paper in a volume devoted exclusively to antitrust law and economics. It summarizes the other papers and addresses two issues. First, after showing that the federal courts generally view consumer welfare as the ultimate goal of antitrust law, it asks what they mean by that term. It concludes that recent decisions appear more likely to equate consumer welfare with the well-being of consumers in the relevant market than with economic efficiency. Second, it asks whether a buyer must possess monopsony power to induce a price discrimination that is not cost justified. It concludes that a buyer can often obtain an unjustified concession simply by wielding bargaining power, but the resulting concession may frequently – though not always – improve consumer welfare.
