The greatest explainers of economics—now beyond the page
Paul Krugman and Robin Wells’ signature storytelling style helps readers understand how economic concepts play out in our world. The new edition, revised and enhanced throughout, now offers holistic digital learning tools as part of SaplingPlus, a complete, integrated online learning system.
Features
New to This Edition
Technology that offers the best value and price. Because students’ needs are changing, our most powerful learning option is now also our most affordable. SaplingPlus is a new digital solution that supports students and instructors at each stage in the learning path, from pre-class to in-class and post-class. It combines LearningCurve with an integrated e-Book, robust homework, an improved Graphing Player, and fully digital end-of-chapter problems including Work It Outs. And if print is important, a package with a loose-leaf copy of the text is only a few dollars more. For programs that are interested, LaunchPad is also available for the fifth edition.
New Discovering Data activities help students interpret, analyze, share, and report on data. Students develop data literacy by completing these new Interactive Activities, step-by-step problems that have students use up-to-the-minute FRED data.
Current events framed by the world’s best communicators of economics. No other text stays as fresh as Krugman and Wells. The authors—who have explained economics to millions through trade books and newspaper columns—offer a new online feature, News Analysis, that pairs journalistic takes on pressing issues with questions based on Bloom’s taxonomy. This complements the text’s unparalleled coverage of current topics: sustainability, the economic impact of technology, pressing policy debates, and much more.
A richer commitment to broadening students’ understanding of the global economy. With unparalleled insight and clarity, the authors use their hallmark narrative approach to take students outside of the classroom and into our global world. Starting with a new opening story on the economic transformation in China’s Pearl River Delta, the global focus is carried throughout with more on the ascendance of China’s economy, the Euro and events in Europe (including Brexit), and post-recession economies around the globe.
Thoroughly updated throughout. The fifth edition has been updated to reflect our always changing world. Along with updated graphs and changes in every chapter in the text, the new edition features 12 new chapter-opening stories, 18 new business cases, and 35 new Economics in Action Applications.

Authors

Paul Krugman
Paul Krugman, recipient of the 2008 Nobel Memorial Prize in Economic Sciences, taught at Princeton University for 14 years. In 2015, he joined the faculty of the Graduate Center of the City University of New York, associated with the Luxembourg Income Study, which tracks and analyzes income inequality around the world. He received his BA from Yale and his PhD from MIT. Before Princeton, he taught at Yale, Stanford, and MIT. He also spent a year on the staff of the Council of Economic Advisers in 1982–1983. His research has included trailblazing work on international trade, economic geography, and currency crises. In 1991, Krugman received the American Economic Association’s John Bates Clark medal. In addition to his teaching and academic research, Krugman writes extensively for nontechnical audiences. He is a regular op-ed columnist for the New York Times. His best-selling trade books include End This Depression Now!, The Return of Depression Economics and the Crisis of 2008, a history of recent economic troubles and their implications for economic policy, and The Conscience of a Liberal, a study of the political economy of economic inequality and its relationship with political polarization from the Gilded Age to the present. His earlier books, Peddling Prosperity and The Age of Diminished Expectations, have become modern classics.

She received her BA from the University of Chicago and her PhD from the University of California, Berkeley; she then did her postdoctoral work at MIT.
