Preface

This Instructor’s Manual serves several functions. For instructors, it provides some help in staying ahead of the many burdens that a full teaching load imposes. For the authors, it provides an opportunity to talk directly to the teachers––to let you know what we had in mind, why we did some things differently in this edition (or in some cases differently than other books do them), and to share with you some of our experiences with teaching the material. Our general philosophy and approach are discussed in the Preface to our text, as are the major revisions in this thirteenth edition of Economics.

There are two types of endofchapter questions in our text, and both can play an important part in the learning process. The Study Exercises are questions designed for the student to work through on their own. These questions will give them practice drawing graphs, shifting curves, computing elasticities, understanding cost concepts, and so on. The Discussion Questions are designed to form the basis of classroom discussions—they are more open-ended than the Study Exercises.

Providing the answers to both sets of questions is one of the most important features of this Instructor’s Manual. The full answers to the Study Exercises, complete with graphs where appropriate, are provided. For the Discussion Questions, there is considerable variation in terms of complexity and in the degree to which there is clearly a “correct” answer. In some cases we have not tried to provide the “correct” answer—often there is none, or there are many—but we always try to identify the important issues that each question raises.

Please note that some of the Study Exercises are assignable in this text’s MyEconLab course ( These questions are marked in the textbook by a blue circle around the exercise number. By selecting only some of the Study Exercises for use in the MyEconLab course, you will still have the opportunity of using some of the questions for in-class quizzes, tests, or as homework assignments.

Finally, we have a simple request. If our book becomes more teachable from edition to edition, as we believe it does, much of the credit goes to teachers who call our attention to errors, omissions, difficulties in exposition, ambiguities, or organizational flaws. While we do not adopt every suggestion, we consider each carefully and act on a large fraction. If you have any suggestions, please write us so that we can continue to incorporate your ideas for improvements. Please send your comments by email to:

We look forward to receiving your comments. Good teaching!
