To our daughters, Maya, Talia, and Shira Sarah and Rachel ABOUT THE AUTHORS The authors, back again for a new edition, reflect on their years of successful textbook collaboration Pindyck is on the right and Rubinfeld on the left R vi evising a textbook every three or four years is hard work, and the last edition was well-liked by students “So why is our publisher pushing for a new edition?” the authors wondered “Were some of the examples becoming stale? Or might it have something to with the used book market?” Could be both In any case, here they are again, with a new edition that has substantial improvements and lots of new examples Robert S Pindyck is the Bank of Tokyo-Mitsubishi Ltd Professor of Economics and Finance in the Sloan School of Management at M.I.T Daniel L Rubinfeld is the Robert L Bridges Professor of Law and Professor of Economics Emeritus at the University of California, Berkeley, and Professor of Law at NYU Both received their Ph.Ds from M.I.T., Pindyck in 1971 and Rubinfeld in 1972 Professor Pindyck’s research and writing have covered a variety of topics in microeconomics, including the effects of uncertainty on firm behavior and market structure; the behavior of natural resource, commodity, and financial markets; environmental economics; and criteria for investment decisions Professor Rubinfeld, who served as chief economist at the Department of Justice in 1997 and 1998, is the author of a variety of articles relating to antitrust, competition policy, law and economics, law and statistics, and public economics Pindyck and Rubinfeld are also co-authors of Econometric Models and Economic Forecasts, another best-selling textbook that makes a perfect gift (birthdays, weddings, bar mitzvahs, you name it) for the man or woman who has everything (Buy several—bulk pricing is available.) These two authors are always looking for ways to earn some extra spending money, so they enrolled as human subjects in a double-blind test of a new hair restoration medication Rubinfeld strongly suspects that he is being given the placebo This is probably more than you want to know about these authors, but for further information, see their Web sites: http://web.mit.edu/rpindyck/www and http://www.law.berkeley.edu/faculty/rubinfeldd BRIEF CONTENTS • PART ONE Introduction: Markets and Prices 1 Preliminaries The Basics of Supply and Demand 21 • PART TWO Producers, Consumers, and Competitive Markets 65 Consumer Behavior 67 Individual and Market Demand 111 Uncertainty and Consumer Behavior 159 Production 201 The Cost of Production 229 Profit Maximization and Competitive Supply 279 The Analysis of Competitive Markets 317 • PART THREE Market Structure and Competitive Strategy 355 10 11 12 13 14 15 Market Power: Monopoly and Monopsony 357 Pricing with Market Power 399 Monopolistic Competition and Oligopoly 451 Game Theory and Competitive Strategy 487 Markets for Factor Inputs 529 Investment, Time, and Capital Markets 559 • PART FOUR Information, Market Failure, and the Role of Government 593 16 17 18 General Equilibrium and Economic Efficiency 595 Markets with Asymmetric Information 631 Externalities and Public Goods 661 Appendix: The Basics of Regression 700 Glossary 708 Answers to Selected Exercises 718 Photo Credits 731 Index 732 vii This page intentionally left blank CONTENTS Preface xvii • P A RT ONE Introduction: Markets and Prices Summary 60 Questions for Review 61 Exercises 62 Preliminaries 1.1 The Themes of Microeconomics Trade-Offs Prices and Markets Theories and Models Positive versus Normative Analysis 1.2 What Is a Market?
