Learning-by-Doing problems throughout the text give students a chance to make economics their own. These fully worked-out problems provide a step-by-step road map to help students solve numerical problems. Each problem correlates to similar practice problems at the end of each chapter. The authors include many extensive real-world examples in the text. These examples are contemporary applications of the theory and are longer and more extensive to show the evolution of the example. Each chapter opens with an example to draw readers into the topic. Over 100 applications make the subject relevant and interesting for students. (For example, Example 10.2 on Scalping Super Bowl Tickets on the Internet.) Math and graphs are integrated and presented in parallel, to help students understand both more deeply and to see the connections between them. This text includes modern topics and a more modern treatment of conventional topics. Examples include - an integrated treatment of game theory, ologopoly, a more detailed treatment of sunk costs, and consumer surplus.
