PRINCIPLES OF ECONOMICS continues to be the most popular and widely used text in economics classrooms today. The fifth edition features a strong revision of content in all 36 chapters while maintaining the clear, accessible writing style and precise presentation that are the hallmark of this highly respected author. Dozens of new applications emphasize the real-world relevance of economics for today's students through interesting news articles, realistic case studies, and engaging problems. The new edition also features an expanded instructor's resource package designed to assist in course planning and classroom presentation, as well as full integration of content with Aplia. "I have tried to put myself in the position of someone seeing economics for the first time. My goal is to emphasize the material that students should and do find interesting about the study of the economy."--N. Gregory Mankiw.
