PART TWO: SUPPLY AND DEMAND I: HOW MARKETS WORK Chapter 4 The Market Forces of Supply and Demand Chapter 5 Elasticity and Its Application Chapter 6 Supply, Demand, and Government Policies How does the economy coordinate interdependent economic actors?

PART THREE: SUPPLY AND DEMAND II: MARKETS AND WELFARE Chapter 7 Consumers, Producers, and the Efficiency of Markets Chapter 8 Application: The Costs of Taxation Chapter 9 Application: International Trade Why is the equilibrium of supply and demand desirable for society as a whole?

Between us, we have many years of experience teaching first-year economics. Like many instructors, we found it harder and harder to teach with each new edition of the thick, standard texts. It was simply impossible to cover all of the material. Of course, we could have skipped sections, features, or whole chapters, but then, apart from the sheer hassle of telling students which bits to read and not to read, and worries about the consistencies and completeness of the remaining material, we ran the risk of leaving students with the philosophy that what matters is only what’s on the exam. We do not believe that the writers of these other books set out with the intention of cramming so much material into them. It is a difficult task to put together the perfect textbook—one that all instructors would approve of and that all students would enjoy using. Therefore, to please all potential users, most of the books end up covering a wide range of topics. And so the books grow and grow. Professor Mankiw made a fresh start in the first U.S. edition. He included all the important topics and presented them in order of importance. And in the fifth U.S. edition, he has resisted the temptation to add more and more material. We have, in adapting the text for Canadian students, taken a minimalist approach: “If it isn’t broken, don’t fix it!” While the book is easily recognizable as Mankiw’s, we have made changes that increase its relevance to Canadian students. Some of these changes reflect important differences between the Canadian and U.S. economies. For example, the Canadian economy is much smaller and more open than the U.S. economy, and this fact is explicitly recognized in this edition. Other changes reflect important institutional differences between the two countries, including the structure of the tax system and the nature of competition policy. Finally, the Canadian edition focuses on issues and includes examples that are more familiar and relevant to a Canadian audience. We would not have agreed to participate in the Canadian edition if we were not extremely impressed with the U.S. edition. Professor Mankiw has done an outstanding job of identifying the key concepts and principles that every firstyear student should learn. It was truly a pleasure to work with such a well-thought-out and well-written book. We have enjoyed teaching from the earlier Canadian editions and we look forward to using the fifth Canadian edition. We hope you do, too. Finally, we wish to acknowledge the contributions of our friend and colleague Nick Rowe of Carleton University. We began our work adapting Professor Mankiw’s book with Nick, and while he decided to leave the project with this edition, his contributions to the book remain and we acknowledge his help and advice. HOW THE BOOK IS ORGANIZED To write a brief and student-friendly book, Mankiw considered new ways to organize familiar material. What follows is a whirlwind tour of this text. The tour, we hope, will give you a sense of how the pieces fit together. NEL xvii Copyright 2010 Cengage Learning. All Rights Reserved. May not be copied, scanned, or duplicated, in whole or in part.

It previews some of the big ideas that recur throughout economics, such as opportunity costs, marginal decision making, the role of incentives, the gain from trade, and the efficiency of market allocations. Throughout the text an effort is made to relate the discussion back to the ten principles of economics introduced in Chapter 1. The interconnections of the material with the ten principles are clearly identified throughout the text. Chapter 2, “Thinking Like an Economist,” examines how economists approach their field of study, discussing the role of assumptions in developing a theory and introducing the concepts of an economic model. It also discusses the role of economists in making policy. The appendix to this chapter offers a brief refresher course on how graphs are used and how they can be abused. Chapter 3, “Interdependence and the Gains from Trade,” presents the theory of comparative advantage. This theory explains why individuals trade with their neighbours, as well as why nations trade with other nations. Much of economics is about how market forces coordinate many individual production and consumption decisions. As a starting point for this analysis, students see in this chapter why specialization, interdependence, and trade can benefit everyone. The Fundamental Tools of Supply and Demand The next three chapters introduce the basic tools of supply and demand. Chapter 4, “The Market Forces of Supply and Demand,” develops the supply curve, the demand curve, and the notion of market equilibrium. Chapter 5, “Elasticity and Its Application,” introduces the concept of elasticity and uses it to analyze events in three different markets. Chapter 6, “Supply, Demand, and Government Policies,” uses these tools to examine price controls, such as rent-control and minimum-wage laws, and tax incidence. Chapter 7, “Consumers, Producers, and the Efficiency of Markets,” extends the analysis of supply and demand using the concepts of consumer surplus and producer surplus. It begins by developing the link between consumers’ willingness to pay and the demand curve, and the link between producers’ costs of production and the supply curve. It then shows that the market equilibrium maximizes the sum of the producer and consumer surplus. Thus, students learn early about the efficiency of market allocations. The next two chapters apply the concepts of producer and consumer surplus to questions of policy. Chapter 8, “Application: The Costs of Taxation,” shows why taxation results in deadweight losses and what determines the size of those losses. Chapter 9, “Application: International Trade,” considers who wins and who loses from international trade and presents the debate over protectionist trade policies. More Microeconomics Having examined why market allocations are often desirable, the book then considers how the government can sometimes improve on them. Chapter 10, “Exter- NEL Copyright 2010 Cengage Learning. All Rights Reserved. May not be copied, scanned, or duplicated, in whole or in part.

Chapter 11, “Public Goods and Common Resources,” considers the problems that arise when goods, such as national defence, have no market price. Chapter 12, “The Design of the Tax System,” describes how the government raises the revenue necessary to pay for public goods. It presents some institutional background about the Canadian tax system and then discusses how the goals of efficiency and equity come into play when designing a tax system. The next five chapters examine firm behaviour and industrial organization. Chapter 13, “The Costs of Production,” discusses what to include in a firm’s costs and introduces cost curves. Chapter 14, “Firms in Competitive Markets,” analyzes the behaviour of price-taking firms and derives the market supply curve. Chapter 15, “Monopoly,” discusses the behaviour of a firm that is the sole seller in its market, the inefficiency of monopoly pricing, the possible policy responses, and the attempts by monopolies to price-discriminate. Chapter 16, “Monopolistic Competition,” looks at behaviour in a market in which many sellers offer similar but differentiated products. It also discusses the debate over the effects of advertising. Chapter 17, “Oligopoly,” covers markets in which there are only a few sellers, using the prisoners’ dilemma as the model for examining strategic interaction. The next three chapters present issues related to labour markets. Chapter 18, “The Markets for the Factors of Production,” emphasizes the link between factor prices and marginal productivity. Chapter 19, “Earnings and Discrimination,” discusses the determinants of equilibrium wages, including compensating differentials, human capital, and discrimination. Chapter 20, “Income Inequality and Poverty,” examines the degree of inequality in Canadian society, alternative views about the government’s role in changing the distribution of income, and various policies aimed at helping society’s poorest members. The final two chapters present optional material. Chapter 21, “The Theory of Consumer Choice,” analyzes individual decision making using budget constraints and indifference curves. Chapter 22, “Frontiers of Microeconomics,” introduces the topics of asymmetric information, political economy, and behavioural economics. Some instructors may skip all or some of this material. Instructors who do cover these topics may choose to assign these chapters earlier than they are presented in this text, and they have been written to give that flexibility.

Toward that end, various learning tools recur throughout the book. Chapter Openers Welldesigned chapter openers act as previews that summarize the major concepts to be learned in each chapter. Case Studies Economic theory is useful and interesting only if it can be applied to understanding actual events and policies. Updated or replaced with more current Canadian examples, this book therefore contains numerous case studies that apply the theory that has just been developed. Figures and Tables Colourful and eye-catching visuals are used to make important economic points and to clarify Canadian and other key economic concepts. These have also proved to be valuable and memorable teaching aids. NEL Copyright 2010 Cengage Learning. All Rights Reserved. May not be copied, scanned, or duplicated, in whole or in part.

To highlight this benefit, there are excerpts from many Canadian news articles, some of which are opinion columns written by prominent economists. These articles show how basic economic theory can be applied. xxi “FYI” Features These features provide additional material “for your information.” Some of them offer a glimpse into the history of economic thought. Others clarify technical issues. Still others discuss supplementary topics that instructors might choose either to discuss or skip in their lectures. Key Concept Definitions When key concepts are introduced in the chapter, they are presented in bold typeface. In addition, their definitions are placed in the margin and in the “Glossary” at the back of the book. This treatment should aid students in learning and reviewing the material. QuickQuizzes After each major section, students are offered a quick quiz to check their comprehension of what they have just learned. If students cannot readily answer these quizzes, they should stop and reread the material before continuing. NEL Copyright 2010 Cengage Learning. All Rights Reserved.

Later in their study, it offers an efficient way to review for exams. List of Key Concepts A list of key concepts at the end of each chapter offers students a way to test their understanding of the new terms that have been introduced. Page references are included so that students can review the terms they do not understand. Questions for Review At the end of each chapter are questions for review that cover the chapter’s primary lessons. Students can use these questions to check their comprehension and to prepare for exams. Problems and Applications Each chapter also contains a variety of problems and applications that ask students to apply the material they have learned. Some instructors may use these questions for homework assignments. Others may use them as a starting point for classroom discussion. NEL Copyright 2010 Cengage Learning. All Rights Reserved.

The primary NETA components are NETA Engagement and NETA Assessment. NETA Engagement The foundational principles underlying NETA Engagement are student-centred learning, deep learning, active learning, and creating positive classroom environments. The NETA Instructor’s Guide to Classroom Engagement (NETA IGCE) provides an overview of the research underlying these principles. The structure of the Classroom Engagement Activities was created by Dr. Roger Fisher and validated by an interdisciplinary editorial advisory board of scholars of teaching and learning. Editorial Advisory Board: Norman Althouse, Haskayne School of Business, University of Calgary Brenda Chant-Smith, Department of Psychology, Trent University Scott Follows, Manning School of Business Administration, Acadia University Glen Loppnow, Department of Chemistry, University of Alberta Tanya Noel, Department of Biology, York University Gary Poole, Director, Centre for Teaching and Academic Growth and School of Population and Public Health, University of British Columbia Dan Pratt, Department of Educational Studies, University of British Columbia The Classroom Engagement Activities for Principles of Microeconomics, Fifth Canadian Edition, were written by Professor Oliver Franke at Concordia University College of Alberta. NETA Assessment Recognizing the importance of multiple-choice testing in today’s classroom and in response to instructors’ concerns, Nelson Education has created the NETA Assessment program. NETA Assessment is a research-based program that improves the quality of our test banks by ensuring our test banks measure not just recall (as is typical with test banks) but higher-level thinking skills as well. The NETA Assessment program was created in partnership with David DiBattista, a 3M National Teaching Fellow, professor of psychology at Brock University, and researcher in the area of multiple-choice testing.
