Preface
xvi
TEXT WITH A MISSION The purpose of Economics for Today, Seventh Edition, is to teach, in an engag- ing style, the basic operations of the U.S. economy to students who will take a two-term economics course. Rather than taking an encyclopedic approach to economic concepts, Economics for Today focuses on the most important tool in economics—supply and demand analysis—and applies it to clearly explain real- world economic issues.
Every effort has been made to make Economics for Today the most “stu- dent friendly” text on the market. This text was written because so many others expose students to a confusing array of economic analyses that force students to simply memorize in order to pass the course. Instead, Economics for Today presents a straightforward and unbiased approach that effectively teaches the application of basic economic principles. After reading this text, the student should be able to say “now that economics stuff in the news makes sense.”
HOW IT FITS TOGETHER The text presents the core principles of microeconomics, macroeconomics, and international economics. The fi rst 14 chapters introduce the logic of economic analysis and develop the core of microeconomic analysis. Here students learn the role of demand and supply in determining prices in competitive versus mo- nopolistic markets. This part of the book explores such issues as minimum wage laws, rent control, and pollution. The next 13 chapters develop the macroeco- nomics part of the text. Using the modern, yet simple, aggregate demand and aggregate supply model, the text explains measurement of and changes in the price level, national output, and employment in the economy. The study of mac- roeconomics also includes how the supply of money and the demand for money infl uence the economy. Finally, the text concludes with three chapters devoted entirely to global issues. For example, students will learn how the supply of and demand for currencies determine exchange rates and what the complications of a strong or a weak dollar are.
TEXT FLEXIBILITY The full version of Economics for Today is easily adapted to an instructor’s preference for the sequencing of microeconomics and macroeconomics topics. The text can be used in a macroeconomic–microeconomic sequence by teaching

the fi rst four chapters and then Parts 5 through 7. Next, microeconomics is covered in Parts 2 through 4. Finally, the course can be completed with Part 8, consisting of three chapters devoted to international economics.
An important design of this text is that it accommodates the two camps for teaching principles of macroeconomics: (1) those who cover both the Keynes- ian Cross and AD/AS models and (2) those who skip the Keynesian model and cover only the AD/AS model. For instructors who prefer the former model se- quence, Economics for Today moves smoothly in Chapters 18–19 (8–9) from the Keynesian model (based on the Great Depression) to the AD/AS model in Chapter 20 (10). For instructors using the latter approach, this text is written so that instructors can skip the Keynesian model in Chapters 18–19 (8–9) and proceed from Chapter 17 (7) to Chapter 20 (10) without losing anything. For example, the spending multiplier is completely covered both in the Keynesian and AD/AS model chapters.
For instructors who wish to teach the self-correcting AD/AS model, emphasis can be placed on the appendixes to Chapters 20 (10) and 26 (16). Instructors who choose not to cover this model can simply skip these appendixes. In short, Economics for Today provides more comprehensive and fl exible coverage of mac- roeconomics models than is available in other texts. Also, a customized text might meet your needs. If so, contact your South-Western/Cengage Learning sales repre- sentative for information.
HOW NOT TO STUDY ECONOMICS To some students, studying economics is a little frightening because many chap- ters are full of graphs. Students often make the mistake of preparing for tests by trying to memorize the lines of graphs. When their graded tests are returned, the students using this strategy will probably exclaim, “What happened?” The answer to this query is that the students should have learned the economic concepts fi rst; then they would understand the graphs as illustrations of these underlying concepts. Stated simply, superfi cial cramming for economics quizzes does not work.
For students who are anxious about using graphs, the appendix to Chap- ter 1 provides a brief review of graphical analysis. In addition, the Graphing Workshop and Study Guide contain step-by-step features on how to interpret graphs.
CHANGES TO THE SEVENTH EDITION The basic layout of the seventh edition remains the same. The following are changes:
Chapter 1 recognizes that students taking introductory college-level • economics courses are considering their major. One reason to select

economics is that the average starting salary for an undergraduate economics major is higher compared to many other majors. To aid their decision, current average starting salary figures for selected majors have been provided.
Chapter 9 on Monopoly presents a new concept, network good, which • updates this chapter by linking economies of scale and monopoly power to the popular Facebook and Match.com Web sites.
Chapter 12 on Income Distribution, Poverty, and Discrimination has been • updated with the latest figures on family income distribution and poverty rates. In addition, the feature articles on Social Security and fair pay for females have been updated. These are all timely features that generate great interest for students.
Chapter 14 on Environmental Economics is among today’s highly • controversial issues. This issue is addressed by new Global Economics features titled “How Should Carbon Emissions Be Reduced: Cap and Trade or Carbon Taxes?” and “Why Is the Climate Change Problem So Hard to Solve?” The Analyze the Issue sections that accompany these features give students an opportunity to participate in this important environmental debate.
Chapter 17 on Inflation updates data on inflation and the You’re the Economist • feature on “How Much More Does It Cost to Laugh?” In addition, a new Checkpoint titled “What Is the Real Price of Gasoline?” is added that provides an application for adjusting the price of gasoline for inflation over time. And here students enjoy learning how to convert Babe Ruth’s 1932 salary into today’s dollars.
Chapter 20(10) on Aggregate Demand and Supply has been revised to provide • a unique, complete, unbiased, and realistic comparison of the Keynesian and self-correction macroeconomic models in contrast to texts that present only or primarily the self-correction model. To enhance student understanding and interest, updated actual CPI and real GDP numbers are used throughout rather than generic Ps and Qs. For example, a new exhibit is added that explains with actual data how decreases in aggregate demand during the current recession caused a movement along the flat Keynesian range of the aggregate supply curve with the CPI constant. Here students can clearly visualize and comprehend the Keynesian argument against the classical school that prices and wages are inflexible downward.
The appendix to Chapter 20(10) fully develops and explains the opposing • self-correction model based on downward flexibility of prices and wages and a downward shifting short-run aggregate supply curve. Only by providing a complete presentation of both the Keynesian and self-correction models can the student understand the current macroeconomic public policy debate.

PREFACE xix
Chapter 21(11) on Fiscal Policy also uses realism as its hallmark by • explaining the stimulus package and the spending multiplier process with real-world updated numbers.
Chapter 22(12) on The Public Sector highlights the important current issue • of the changing economic character of the United States with global comparisons to other countries. Here, for example, updated data traces the growth of U.S. government expenditures and taxes since the Great Depression. And U.S. spending and taxation are compared to other countries. An explanation of the Value Added Tax (VAT) has been added to the You’re the Economist feature discussion of the flat tax and national sales tax.
Chapter 23(13) on Federal Deficits, Surpluses, and the National Debt • focuses on the current “hot button” issue of federal deficits and the national debt using updated data and exhibits. This chapter now includes a discussion of the “PayGo” rule and a new exhibit giving a global comparison of the national debt as a percentage of GDP. The current financial crisis in Greece is included in the chapter debate over the consequences of the U.S. national debt.
Chapter 26(16) on Monetary Policy has been updated using actual data in • the model that link changes in the money supply and changes in the aggregate demand curve required to restore the economy to full employment. Students’ interest is enhanced by adding a set of exhibits comparing monetary policy during the Great Depression to monetary policy during the current Great Recession.
The final three chapters of the text are the international chapters, and each • has been updated. For example, the chapter on International Trade and Finance explains the recent sharp decline in the U.S. balance of trade. The chapter on Economies in Transition contrasts privatization in Cuba, Russia, and China to recent nationalization in the United States. And the chapter on Growth and the Less-Developed Countries presents updated data used to explain, for example, the link between economic freedom and quality-of-life indicators.
New lecture PowerPoint• ® slides have been developed by the author and tested in his classroom.

MOTIVATIONAL PEDAGOGICAL FEATURES Economics for Today strives to motivate and advance the boundaries of peda- gogy with the following features:
Part Openers Each part begins with a statement of the overall mission of the chapters in the part. In addition, there is a nutshell introduction of each chapter in relation to the part’s learning objective.
Chapter Previews Each chapter begins with a preview designed to pique the student’s interest and reinforce how the chapter fi ts into the overall scheme of the book. Each preview appeals to the student’s “Sherlock Holmes” impulses by posing several economics puzzles that can be solved by understanding the material presented in the chapter.
Margin Definitions and Flashcards Key concepts introduced in the chapter are highlighted in bold type and then defi ned with the defi nitions again in the margins. This feature therefore serves as a quick reference. Key terms are also defi ned on the Tucker Web site with a Flashcard feature that is great for learning terms.
You’re the Economist Each chapter includes boxed inserts that provide the acid test of “relevance to everyday life.” This feature gives the student an opportunity to encounter timely, real-world extensions of economic theory. For example, students read about

PREFACE xxi
Fred Smith as he writes an economics term paper explaining his plan to create FedEx. To ensure that the student wastes no time fi guring out which concepts apply to the article, applicable concepts are listed after each title. Many of these boxed features include quotes from newspaper articles over a period of years demonstrating that economic concepts remain relevant over time.
Conclusion Statements Throughout the chapters, highlighted conclusion statements of key concepts ap- pear at the ends of sections and tie together the material just presented. Students will be able to see quickly if they have understood the main points of the sec- tion. A summary of these conclusion statements is provided at the end of each chapter.
Global Economics Today’s economic environment is global. Economics for Today carefully inte- grates international topics throughout the text and presents the material using a highly readable and accessible approach designed for students with no training in international economics. All sections of the text that present global econom- ics are identifi ed by a special global icon in the text margin and in the Global Economics boxes. In addition, the fi nal three chapters of the book are devoted entirely to international economics.
Analyze the Issue This feature follows each You’re the Economist and Global Economics feature and asks specifi c questions that require students to test their knowledge of how the material in the boxed insert is relevant to the applicable concept. To allow these questions to be used in classroom discussions or homework assignments, answers are provided in the Instructor’s Manual rather than the text.
Checkpoint Watch for these! Who said learning economics can’t be fun? This feature is a unique approach to generating interest and critical thinking. These questions spark students to check their progress by asking challenging economics puzzles in game-like style. Students enjoy thinking through and answering the questions, and then checking the answers at the end of the chapter. Students who answer correctly earn the satisfac- tion of knowing they have mastered the concepts.

Illustrations Attractive large graphical presentations with grid lines and real-world num- bers are essential for any successful economics textbook. Each exhibit has been carefully analyzed to ensure that the key concepts being represented stand out clearly. Brief descriptions are included with graphs to provide guidance for stu- dents as they study the graph. When actual data are used, the Web site reference is provided so that students can easily locate the data source.
Causation Chains Game This will be one of your favorites. The highly successful causation chains are in- cluded under many graphs throughout the text. This pedagogical device helps stu- dents visualize complex economic relationships in terms of simple box diagrams that illustrate how one change causes another change. Each exhibit having a cau- sation chain in the text is included in the Animated Causation Chains game on the Tucker Web site (www.cengage.com/economics/tucker). This game makes it fun to learn. Arrange the blocks correctly and hear the cheers.
Key Concepts Key concepts introduced in the chapter are listed at the end of each chapter and on the Tucker Web site (www.cengage.com/economics/tucker). As a study aid, you can use the key concepts as fl ashcards to test your knowledge. First state the defi - nition and then click on the term to check for correctness.
Visual Summaries Each chapter ends with a brief point-by-point summary of the key concepts. Many of these summarized points include miniaturized versions of the important graphs and causation chains that illustrate many of the key concepts. These are intended to serve as visual reminders for students as they fi nish the chapters and are also useful in reviewing and studying for quizzes and exams.
Study Questions and Problems The end-of-chapter questions and problems offer a variety of levels ranging from straightforward recall to deeply thought-provoking applications. The an- swers to odd questions and problems are in the back of the text. This feature gives students immediate feedback without requiring the instructor to check their work.

PREFACE xxiii
End-of-Chapter Practice Quizzes A great help before quizzes. Many instructors test students using multiple-choice questions. For this reason, the fi nal section of each chapter provides the type of multiple-choice questions given in the instructor’s Test Bank. The answers to all of these questions are given in the back of the text. In addition, students may visit the Tucker Web site (www.cengage.com/economics/tucker) and answer these questions online where an explanation of each correct answer is given.
Part Road Map This feature concludes each part with review questions listed by chapter from the previous part. To reinforce the concepts, each set of questions relates to the in- teractive causation chain game. Click on the Tucker Web site (www.cengage.com/ economics/tucker) and make learning fun listening to the cheers when correct and jeers for a wrong answer. Answers to the questions are in the back of the text.
Interactive Quizzes In addition to the end-of-chapter practice quizzes, there are additional multiple- choice questions written by the author on the Tucker Web site (www.cengage. com/economics/tucker). Each quiz contains multiple questions like those found on a typical exam. Feedback is included for each answer so that you may know instantly why you have answered correctly or incorrectly. In addition, you may email yourself and/or your instructor the quiz results with a listing of correct and incorrect answers. Between this feature and the end-of-chapter practice quizzes, students are well prepared for tests.
Online Exercises These exercises for each chapter are designed to spark students’ excitement about researching on the Internet by asking them to access online economic data and then answer questions related to the content of the chapter. All Internet exercises are on the Tucker Web site (www.cengage.com/economics/tucker) with direct links to the addresses so that students will not have the tedious and error-prone task of entering long Web site addresses.
Learning Objectives Learning objectives link sections in the text and steps to achieve learning objec- tives. The steps include reference to “Ask the Instructor Video Clips” and the “Graphing Workshop” available through the CourseMate Web site.

1Introduction to Economics
The first two chapters introduce you to a foundation of economic knowledge vital to understanding the other chapters in the text. In these introductory chapters, you will begin to learn a valuable reasoning approach to solving economics puzzles that economists call “the economic way of thinking.” Part 1 develops the cornerstone of this type of logi- cal analysis by presenting basic economic models that explain such important topics as scarcity, opportunity cost, production possibilities, and economic growth.

Welcome to an exciting and useful subject
economists call “the economic way of thinking.”
As you learn this reasoning technique, it will
become infectious. You will discover that the world
is full of economics problems requiring more
powerful tools than just common sense. As you
master the methods explained in this book, you
will appreciate economics as a valuable reasoning
approach to solving economics puzzles. Stated
differently, the economic way of thinking is
important because it provides a logical framework
for organizing your thoughts and understanding an
economic issue or event. Just to give a sneak
preview, in later chapters you will study the perils
of government price fixing for gasoline and health
care. You will also find out why colleges and
universities charge students different tuitions for
the same education. You will investigate whether
you should worry if the federal government fails to
balance its budget. You will learn that the island of
Yap uses large stones with holes in the center as
money. In the final chapter, you will study why
some countries grow rich while others remain poor
and less developed. And the list of fascinating
and relevant topics continues throughout each
chapter. As you read these pages, your efforts will
be rewarded by an understanding of just how
economic theories and policies affect our daily
lives—past, present, and future.
Chapter 1 acquaints you with the foundation
of the economic way of thinking. The first building
blocks joined are the concepts of scarcity and
choice. The next building blocks are the steps in
the model-building process that economists use to
study the choices people make. Then we look at
some pitfalls of economic reasoning and explain
why economists might disagree with one another.
The chapter concludes with a discussion of why
you may wish to be an economics major.

In this chapter, you will learn to solve these economics puzzles:
Can you prove there is no person worth a trillion dollars?•
Why would you purchase more Coca-Cola when the price increases?•
How can we explain the relationship between the Super Bowl winner and • changes in the stock market?
THE PROBLEM OF SCARCITY Our world is a fi nite place where people, both individually and collectively, face the problem of scarcity. Scarcity is the condition in which human wants are for- ever greater than the available supply of time, goods, and resources. Because of scarcity, it is impossible to satisfy every desire. Pause for a moment to list some of your unsatisfi ed wants. Perhaps you would like a big home, gourmet meals, designer clothes, clean air, better health care, shelter for the homeless, more leisure time, and so on. Unfortunately, nature does not offer the Garden of Eden, where every desire is fulfi lled. Instead, there are always limits on the economy’s ability to satisfy unlim- ited wants. Alas, scarcity is pervasive, so “You can’t have it all.”
You may think your scarcity problem would disappear if you were rich, but wealth does not solve the problem. No matter how affl uent an individual is, the wish list continues to grow. We are familiar with the “rich and famous” who never seem to have enough. Although they live well, they still desire fi ner homes, faster planes, and larger yachts. In short, the condition of scarcity means all individuals, whether rich or poor, are dissatisfi ed with their material well-being and would like more. What is true for individuals also applies to society. Even Uncle Sam can’t escape the problem of scarcity because the federal government never has enough money to spend for the poor, education, highways, police, national defense, Social Security, and all the other programs it wishes to fund.
