Principles of Macroeconomics, Fifth Canadian Edition, became a best seller after its introduction and continues to be the most popular and widely used text in the economics classroom. Instructors found it to be the perfect complement to their teaching. A text by superb writers and economists that stressed the most important concepts without overwhelming students with an excess of detail was a formula that was quickly imitated, but has yet to be matched. The fifth edition contains extensively updated coverage of areas impacted by the financial crisis and features new content and applications that emphasize the real-world relevance of economics for todays students through interesting news articles, realistic case studies, and engaging problems. The premier ancillary package is the most extensive in the industry and meets the high standards set in the Nelson Education Teaching Advantage guidelines. The text material is again fully integrated into Aplia, the best-selling online homework solution. 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.
