This second edition of Microeconomics is filled with learning-by-doing problems that 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. In addition, 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.
