PROVEN. TRUSTED. Managerial Economics and Business Strategy is the best-selling managerial economics textbook on the market today. Michael Baye provides students with tools like intermediate microeconomics, game theory, and industrial organization that are crucial to making sound managerial decisions. The Seventh Edition discusses the latest issues and research shaping managerial economics today.

KEY FEATURES OF THIS NEW EDITION INCLUDE:

UPDATED HEADLINES: Updated and current Headlines begin each chapter with a real-world economic problem. These problems are essentially hand-picked “mini-cases” designed to motivate students to better understand the chapter material.

NEW AND UPDATED INSIDE BUSINESS APPLICATIONS: New Inside Business boxes illustrate real-world applications of theory developed in the chapter; these examples are drawn from both current economic literature and the popular press.

TIME WARNER CASE STUDY: A Case Study in business strategy — Challenges at Time Warner — follows Chapter 14. The case engages students by applying core elements from managerial economics to a rich business environment.

PREFACE TO THE SEVENTH EDITION

Thanks to feedback from users around the world, Managerial Economics and Busi- ness Strategy remains the top selling managerial text in the market. I am grateful to all of you for allowing me to provide this updated and improved product. Before highlighting some of the new features of the seventh edition, I would like to stress that the fundamental goal of the book—providing students with the tools from intermediate microeconomics, game theory, and industrial organization that they need to make sound managerial decisions—has not changed.

This book begins by teaching managers the practical utility of basic economic tools such as present value analysis, supply and demand, regression, indifference curves, isoquants, production, costs, and the basic models of perfect competition, monopoly, and monopolistic competition. Adopters and reviewers also praise the book for its real-world examples and because it includes modern topics not con- tained in any other single managerial economics textbook: oligopoly, penetration pricing, multistage and repeated games, foreclosure, contracting, vertical and hori- zontal integration, networks, bargaining, predatory pricing, principal–agent prob- lems, raising rivals’ costs, adverse selection, auctions, screening and signaling, search, limit pricing, and a host of other pricing strategies for firms enjoying mar- ket power. This balanced coverage of traditional and modern microeconomic tools makes it appropriate for a wide variety of managerial economics classrooms. An increasing number of business schools are adopting this book to replace (or use alongside) managerial strategy texts laden with anecdotes but lacking the micro- economic tools needed to identify and implement the business strategies that are optimal in a given situation.

This seventh edition of Managerial Economics and Business Strategy has been thoroughly updated but retains all of the content that made previous editions suc- cessful. The basic structure of the textbook is unchanged.

KEY PEDAGOGICAL FEATURES

The seventh edition retains all of the class-tested features of previous editions that enhance students’ learning experiences and make it easy to teach from this book.

Headlines

As in previous editions, each chapter begins with a Headline that is based on a real- world economic problem—a problem that students should be able to address after completing the chapter. These Headlines are essentially hand-picked “mini-cases” designed to motivate students to learn the material in the chapter. Each Headline is

bay75969_fm_i-xxxii.qxd 8/20/09 14:58 Page vii Confirming Pages

viii Preface

answered at the end of the relevant chapter—when the student is better prepared to deal with the complications of real-world problems. Reviewers as well as users of previous editions praise the Headlines not only because they motivate students to learn the material in the chapter, but also because the answers at the end of each chapter help students learn how to use economics to make business decisions.

Learning Objectives

Each chapter includes learning objectives designed to enhance the learning experi- ence.

Demonstration Problems

The best way to learn economics is to practice solving economic problems. So, in addition to the Headlines, each chapter contains many Demonstration Problems sprinkled throughout the text, along with detailed answers. This provides students with a mechanism to verify that they have mastered the material and reduces the cost to students and instructors of having to meet during office hours to discuss answers to problems.

Inside Business Applications

Each chapter contains boxed material (called Inside Business applications) to illus- trate how theories explained in the text relate to a host of different business situa- tions. As in previous editions, I have tried to strike a balance between applications drawn from the current economic literature and the popular press.

Calculus and Noncalculus Alternatives

Users can easily include or exclude calculus-based material without losing content or continuity. That’s because the basic principles and formulae needed to solve a particular class of economic problems (e.g., MR � MC) are first stated without appealing to the notation of calculus. Immediately following each stated principle or formula is a clearly marked Calculus Alternative. Each of these calculus alterna- tives states the preceding principle or formula in calculus notation, and explains the relation between the calculus and noncalculus formula. More detailed calculus der- ivations are relegated to Appendices. Thus, the book is designed for use by instruc- tors who want to integrate calculus into managerial economics and by those who do not require students to use calculus.

Key Terms and Marginal Definitions

Each chapter ends with a list of key terms and concepts. These provide an easy way for instructors to glean material covered in each chapter and for students to check their mastery of terminology. In addition, marginal definitions are provided throughout the text.

Preface ix

End-of-Chapter Problems

Three types of problems are offered. Highly structured but nonetheless challenging Conceptual and Computational Questions stress fundamentals. These are followed by Problems and Applications, which are far less structured and, like real-world deci- sion environments, may contain more information than is actually needed to solve the problem. Many of these applied problems are based on actual business events.

Additionally, the Time Warner case that follows Chapter 14 includes 14 prob- lems called Memos that have a “real-world feel” and complement the text. All of these case-based problems may be assigned on a chapter-by-chapter basis as spe- cific skills are introduced, or as part of a capstone experience. Solutions to all of the memos are contained online at www.mhhe.com/baye7e.

Answers to selected end-of-chapter Conceptual and Computational Questions are presented at the end of the book; detailed answers to all problems—including Problems and Applications and the Time Warner case Memos, are available to instructors on the password-protected Web site.

Case Study

A case study in business strategy—Challenges at Time Warner—follows Chapter 14 and was prepared by Kyle Anderson, Michael Baye, and Dong Chen especially for this text. It can be used either as a capstone case for the course or to supplement individual chapters. The case allows students to apply core elements from manage- rial economics to a remarkably rich business environment. Instructors can use the case as the basis for an “open-ended” discussion of business strategy, or they can assign specific “memos” (contained at the end of the case) that require students to apply specific tools from managerial economics to the case. Teaching notes, as well as solutions to all of the memos, are provided on the Web site.

Flexibility

Instructors of managerial economics have genuinely heterogeneous textbook needs. Reviewers and users continue to praise the book for its flexibility, and assure us that sections or even entire chapters can be excluded without losing continuity. For instance, an instructor wishing to stress microeconomic fundamentals might choose to cover Chapters 2, 3, 4, 5, 8, 9, 10, 11, and 12. An instructor teaching a more applied course that stresses business strategy might choose to cover Chapters 1, 2, 3, 5, 6, 7, 8, 10, 11, and 13. Each may choose to include additional chapters (for example, Chapter 14 or the Time Warner case) as time permits. More generally, instructors can easily omit topics such as present value analysis, regression, indif- ference curves, isoquants, or reaction functions without losing continuity.

Online Resources at www.mhhe.com/baye7e

A large assortment of student supplements for Managerial Economics and Business Strategy are available online at www.mhhe.com/baye7e. This includes data for the Time Warner case Memos, data needed for various end-of-chapter problems, spreadsheet

versions of key tables in the text to enable students to see how key economic concepts—like marginal cost and profit maximization—can be implemented on stan- dard spreadsheets, and spreadsheet macros that students can use to find the optimum price and quantity under a variety of market settings, including monopoly, Cournot oli- gopoly, and Stackelberg oligopoly. Plus, the Web site includes 10 additional full-length cases (in pdf format) that are described below.

SUPPLEMENTS

I am pleased to report that the seventh edition of Managerial Economics and Busi- ness Strategy truly offers adopters the most comprehensive and easily accessible supplements in the market. Below I discuss popular features of some of the supple- ments that have been greatly expanded for this edition.

Cases

In addition to the Time Warner case, the Web site contains nearly a dozen full- length cases that I prepared along with Patrick Scholten to accompany Managerial Economics and Business Strategy. These cases complement the textbook by show- ing how real-world businesses use tools like demand elasticities, markup pricing, third-degree price discrimination, bundling, Herfindahl indices, game theory, and predatory pricing to enhance profits or shape business strategies. The cases are based on actual decisions by companies that include Microsoft, Heinz, Visa, Sta- ples, American Airlines, Sprint, and Kodak. Instructors who adopt the seventh edi- tion obtain the cases on the Web site.

The Web site for the seventh edition contains expanded teaching notes and solutions for all of the cases—including the Time Warner case.

PowerPoint Slides

The Web site also contains thoroughly updated and fully editable PowerPoint presen- tations with animated figures and graphs to make teaching and learning a snap. For instance, a simple mouse click reveals the firm’s demand curve. Another click reveals the associated marginal revenue curve. Another click shows the firm’s marginal cost. A few more clicks, and students see how to determine the profit-maximizing output, price, and maximum profits. Animated graphs and tables are also provided for all other

relevant concepts (like Cournot and Stackelberg equilibrium, normal form and exten- sive form games, and the like).

Instructor’s Manual/Test Bank

A thoroughly updated instructor’s manual and test bank, prepared by Michael R. Baye and Patrick Scholten, provides a summary of each chapter, a teaching outline for each chapter, complete answers to all end-of-chapter problems, updated and class-tested problems (including over 1,000 multiple-choice questions and over 250 problems with detailed solutions). The seventh edition Web site contains teaching notes for the Time Warner case and solutions to the 14 accompanying Memos, as well as expanded and improved teaching notes for the additional cases.

EZ Test Version of the Test Bank

The password-protected Web site contains test bank files in both EZ Test software as well as in Microsoft Word format. EZ Test can reproduce high-quality graphs from the test bank and allows instructors to generate multiple tests with versions that are “scrambled” to be distinctive. The software is easy to use and allows optimum cus- tomization of tests.

Digital Image Library

The Digital Image Library contains all the figures in the textbook in electronic for- mat. This gives instructors the flexibility to integrate figures from the textbook into PowerPoint presentations or to directly print the figures on overhead transparencies.

Study Guide

In addition to the numerous problems and answers contained in the textbook, an updated study guide prepared by yours truly is available to enhance student per- formance at minimal cost to students and professors.

Student Web Site

Please visit the enhanced Web site for Managerial Economics and Business Strategy at www.mhhe.com/baye7e. This site provides a host of information for students and instructors, including online quizzes, PowerPoint presentations, Inside Business applications from previous editions of the text, sample problems from the Study Guide, and other material designed to help students and instructors more effectively use both the textbook and Study Guide.

Instructor Web Site

Electronic versions of all instructor supplements (including the full-length cases complete with teaching notes, PowerPoint presentations, Digital Image Library, the electronic test bank, detailed solutions to every end-of-chapter problem and Time Warner case, chapter outlines, chapter summaries, and more) may be conveniently accessed on the password-protected Instructor's Web site. This makes it easy for instructors to use the many supplements designed to make teaching managerial economics from the seventh edition easy and fun.

CHANGES IN THE SEVENTH EDITION

I have made every effort to update and improve Managerial Economics and Busi- ness Strategy while assuring a smooth transition to the seventh edition. Below is a summary of the pedagogical improvements, enhanced supplements, and content changes that make the seventh edition an even more powerful tool for teaching and learning managerial economics and business strategy.

• All of the class-tested problems from the previous edition, plus over 25 new end-of-chapter problems. Where appropriate, problems from the previous edition have been updated to reflect the current economic climate.

• Updated Test Bank available on the Instructor’s Web site in two formats: Computerized (EZ Test) and in Microsoft Word format.

• Updated Headlines. • New and updated Inside Business applications. • The financial crisis is reshaping the global economic and regulatory

landscape, and it is likely to take years for its ultimate effects on the economy to be fully recognized. In preparing this edition, I have revised the book to ensure that the economic examples presented are timeless and will not grow into “historical examples” as a result of bankruptcies, new legislation, or changes in the country’s taste for regulation. As in previous editions, this edition continues to equip students with the economic tools required to manage businesses and, more generally, to evaluate current events. The virtues of markets, as well as potential market failures, are presented without editorial comment on my part. Adopters of this book have praised this approach, as it provides a positive foundation that permits individual instructors to rigorously discuss current events—including the plethora of political proposals and opinions regarding the financial crisis that emerge each and every day.

• Updated Instructor’s Web site that offers full teaching notes and solutions to Memos for the Time Warner case—plus a host of additional supplements. These include over 10 additional full-length cases complete with expanded teaching notes and links to chapter content, complete solutions to all end-of- chapter problems, an updated and expanded electronic test bank, animated PowerPoint presentations, chapter summarie
