When it was first published a quarter of a century ago, Richard Posner's exposition and defense of an economic approach to antitrust law was a jeremiad against the intellectual disarray that then characterized the field. As other perspectives on antitrust law have fallen away, Posner's book has played a major role in transforming the field of antitrust law into a body of economically rational principles largely in accord with the ideas set forth in the first edition. Today's antitrust professionals may disagree on specific practices and rules, but most litigators, prosecutors, judges, and scholars agree that the primary goal of antitrust laws should be to promote economic welfare, and that economic theory should be used to determine how well business practices conform to that goal. In this thoroughly revised edition, Posner explains the economic approach to new generations of lawyers and students. He updates and amplifies his approach as it applies to the developments, both legal and economic, in the antitrust field since 1976. The "new economy," for example, has presented a host of difficult antitrust questions, and in an entirely new chapter, Posner explains how the economic approach can be applied to new industries such as software manufacturers, Internet service providers, and those that provide communications equipment and services. "The antitrust laws are here to stay," Posner writes, "and the practical question is how to administer them better-more rationally, more accurately, more expeditiously, more efficiently." This fully revised classic will continue to be the standard work in the field.

New England's economy has a history as dramatic as any in the world. From an inauspicious beginning--as immigration ground to a halt in the eighteenth century--New England went on to lead the United States in its transformation from an agrarian to an industrial economy. And when the rest of the country caught up in the mid-twentieth century, New England reinvented itself as a leader in the complex economy of the information society. Engines of Enterprise tells this dramatic story in a sequence of narrative essays written by preeminent historians and economists. These essays chart the changing fortunes of entrepreneurs and venturers, businessmen and inventors, and common folk toiling in fields, in factories, and in air-conditioned offices. The authors describe how, short of staple crops, colonial New Englanders turned to the sea and built an empire; and how the region became the earliest home of the textile industry as commercial fortunes underwrote new industries in the nineteenth century. They show us the region as it grew ahead of the rest of the country and as the rest of the United States caught up. And they trace the transformation of New England's products and exports from cotton textiles and machine tools to such intangible goods as education and software. Concluding short essays also put forward surprising but persuasive arguments--for instance, that slavery, while not prominent in colonial New England, was a critical part of the economy; and that the federal government played a crucial role in the development of the region's industrial skills.
