These laws are one of the most contentious areas of international trade policy. Barfield believes antidumping laws are fundamentally at odds with the free trade policies that have dramatically improved global economic welfare over the past half-century, and their application, while problematic in any sector, is particularly troublesome in high-technology sectors. The study analyzes how U.S. antidumping actions have been applied in four industries: supercomputers, flat-panel displays, semiconductors, and steel.

In each case, the cost to the U.S. economy far outweighed the benefits to the protected industry. Barfield concludes by offering a series of recommendations - including repealing antidumping laws and substituting antitrust actions, or substituting safeguard actions for antidumping - for reforming, if not
