The seventeenth edition has been revised with an eye toward improving this presentation and updating the applications as well as including the latest theoretical developments. Like its predecessors, this edition is intended for use in a one-quarter or one-semester course for students having no more background than principles of economics. This book’s strengths are its clarity, organization, and applications that demonstrate the usefulness of theory to students. The revised and updated material in this edition emphasizes current applications of economic theory and incorporates recent theoretical and policy developments in international trade and finance. Here are some examples.第十七版已经修订，旨在改进本演示文稿，更新应用程序以及包括最新的理论发展。像它的前辈，这个版本是为一个季度或一个学期的学生没有更多的背景比经济学原理课程使用。这本书的优点在于它的清晰性、组织性和应用性，向学生展示了理论的有用性。本版修订和更新的材料强调了经济理论的当前应用，并纳入了国际贸易和金融领域的最新理论和政策发展。这里有一些例子。
