Most chapters of this book include Case Studies illustrating how the principles of economics can be applied. In addition, In the News boxes offer excerpts from newspapers, magazines, and online news sources showing how economic ideas shed light on current issues facing society. After students finish their first course in economics, they should think about news stories from a new perspective and with greater insight. To keep the study of economics fresh and relevant for each new cohort of students, I update each edition of this text to keep pace with the ever-changing world.

这本书的大部分章节都包括了案例研究，说明了这些原则是如何产生的。此外，在新闻栏中还提供了报纸、杂志和在线新闻来源的节选，展示了经济理念如何揭示当前社会面临的问题。在学生完成第一门经济学课程后，他们应该从一个新的角度和更深刻的见解来思考新闻故事。为了使经济学的研究保持新鲜和相关的每一个新的队列的学生，我更新每一个版本的文本，以跟上不断变化的世界。
