What’s New and Improved?
One of the benefits of writing a successful text is the opportunity to revise—to delete the outdated and install the new, to rewrite misleading or ambiguous statements, to introduce more relevant illustrations, to improve the organizational structure, and to enhance the learning aids.

We trust that you will agree that we have used this opportunity wisely and fully. Some of the more significant changes include the following:

New and Updated “Illustrating the Idea,” “Applying the Analysis,” and “Photo Op” Pieces
These examples, applications, and illustrations help drive home central economic ideas in a student-oriented, realworld manner. New content includes a discussion of beekeepers to explain the Coase Theorem, analysis of the effects of rising gas prices on companies like FedEx and Symantec, and an illustration of federal versus state and local spending.

New Discussions of the Financial Crisis and the Recession
In this edition, we have focused on incorporating an analysis of the financial crisis, the recession, and the hesitant recovery into our discussions of macroeconomics. Although we found many ways to work the recession into our macro chapters, we are confident that our basic macroeconomic models will serve equally well in explaining economic recovery and expansion back to the economy’s historical growth path. The new inclusions relating to the recession simply help students see the relevance of the models to what they are seeing in the news and perhaps experiencing in their own lives. The overall tone of the book, including the macro, continues to be optimistic with respect to the long-term growth prospects of market economies.

Reworked End-of-Chapter Questions and Problems
We have extensively reworked the end-of-chapter questions, and we have added new problems to each chapter. The questions are analytic and often ask for free responses, whereas the problems are mainly quantitative. We have aligned the questions and problems with the learning objectives presented at the beginning of the chapters. All of the questions and problems are assignable through McGraw Hill’s Connect Economics, and many contain additional algorithmic variations and can be automatically graded within the system.
