Paul Krugman，Robin Wells
Many of the stories economists tell take the form of models—for whatever else they are, economic models are stories about how the world works. But we believed that students’ understanding of and appreciation for models would be greatly enhanced if they were presented, as much as possible, in the context of stories about the real world, stories that both illustrate economic concepts and touch on the concerns we all face as individuals living in a world shaped by economic forces.
Those stories have been integrated into every edition, including this one. Once again, you’ll find them in the openers, in special features like Economics in Action, For Inquiring Minds, Global Comparison, and in our business cases. We have been gratified by the reception this storytelling approach has received and in this edition of Economics we continue to expand the book’s appeal by including many new stories on a broad range of topics, and by updating and revising others. Specifically, there are 13 new opening stories, 27 new Economics in Actions, and 8 new business cases. As always, a significant number of the features that aren’t completely new have been updated.
