Guell (pronounced “Gill”) is a professor of economics at Indiana State University in Terre Haute, Indiana. He earned a B.A. in statistics and economics in 1986 and an M.S. in economics one year later from the University of Missouri–Columbia. In 1991, he earned a Ph.D. from Syracuse University, where he discovered the thrill of teaching. He has taught courses for freshmen, upper-division undergraduates, and graduate students from the principles level, through public finance, all the way to mathematical economics and econometrics. Dr. Guell has published numerous peer-reviewed articles in scholarly journals. He has worked extensively in the area of pharmaceutical economics, suggesting that the private market’s patent system, while necessary for drug innovation, is unnecessary and inefficient for production. In 1998, Dr. Guell was the youngest faculty member ever to have been given Indiana State University’s Caleb Mills Distinguished Teaching Award. His talent as a champion of quality teaching was recognized again in 2000 when he was named project manager for the Lilly Project to Transform the First-Year Experience, a Lilly Endowment–funded project to raise first-year persistence rates at Indiana State University. He was ISU’s Coordinator of First-Year Programs until January 2008, when he happily stepped aside to rejoin his depart- ment full time. Dr. Guell’s passion for teaching economics led him to request an assignment with the larg- est impact. The one-semester general education basic economics course became the vehicle to express that passion. Unsatisfied with the books available for the course, he made it his calling to produce what you have before you today—an all-in-one readable issues-based text. vii Brief Contents Preface xviii Issues for Different Course Themes xxviii Required Theory Table xxx 1 Economics: The Study of Opportunity Cost 1 2 Supply and Demand 19 3 The Concept of Elasticity and Consumer and Producer Surplus 40 4 Firm Production, Cost, and Revenue 56 5 Perfect Competition, Monopoly, and Economic versus Normal Profit 68 6 Every Macroeconomic Word You Ever Heard: Gross Domestic Product, Inflation, Unemployment, Recession, and Depression 79 7 Interest Rates and Present Value 98 8 Aggregate Demand and Aggregate Supply 107 9 Fiscal Policy 119 10 Monetary Policy 131 11 Federal Spending 145 12 Federal Deficits, Surpluses, and the National Debt 155 13 The Housing Bubble 168 14 The Recession of 2007–2009: Causes and Policy Responses 177 15 Is Economic Stagnation the New Normal? 186 16 Is the (Fiscal) Sky Falling?: An Examination of Unfunded Social Security, Medicare, and State and Local Pension Liabilities 193 17 International Trade: Does It Jeopardize American Jobs? 201 18 International Finance and Exchange Rates 213 19 European Debt Crisis 222 20 Economic Growth and Development 231 21 NAFTA, CAFTA, GATT, TPP, WTO: Are Trade Agreements Good for Us? 238 22 The Line between Legal and Illegal Goods 248 23 Natural Resources, the Environment, and Climate Change 258 24 Health Care 271 25 Government-Provided Health Insurance: Medicaid, Medicare, and the Children’s Health Insurance Program 283 26 The Economics of Prescription Drugs 296 27 So You Want to Be a Lawyer: Economics and the Law 304 28 The Economics of Crime 310 29 Antitrust 319 30 The Economics of Race and Sex Discrimination 327 31 Income and Wealth Inequality: What’s Fair? 339 32 Farm Policy 349 33 Minimum Wage 358 34 Ticket Brokers and Ticket Scalping 366 35 Rent Control 373 36 The Economics of K–12 Education 379 37 College and University Education: Why Is It So Expensive? 390 viii Brief Contents 38 Poverty and Welfare 400 39 Head Start 411 40 Social Security 418 41 Personal Income Taxes 429 42 Energy Prices 440 43 If We Build It, Will They Come?

All Rights Reserved. Authorized only for instructor use in the classroom. No reproduction or distribution without the prior written consent of McGraw-Hill Education. Chapter 8 Learning Objectives Identify the conditions under which a firm operates as perfectly competitive, monopolistically competitive, or a monopoly. Identify sources of (and strategies for obtaining) monopoly power. Apply the marginal principle to determine the profit-maximizing price and output. Show the relationship between the elasticity of demand for a firm’s product and its marginal revenue. Explain how long-run adjustments impact perfectly competitive, monopoly, and monopolistically competitive firms; discuss the ramifications of each of these market structures on social welfare. Decide whether a firm making short-run losses should continue to operate or shut down its operations. Illustrate the relationship between marginal cost, a competitive firm’s short-run supply curve, and the competitive industry supply; explain why supply curves do not exist for firms that have market power. Calculate the optimal output of a firm that operates two plants and the optimal level of advertising for a firm that enjoys market power. © 2017 by McGraw-Hill Education. All Rights Reserved. 2 Perfect Competition Perfectly competitive markets are characterized by: The interaction between many buyers and sellers that are “small” relative to the market. Each firm in the market produces a homogeneous (identical) product. Buyers and sellers have perfect information. No transaction costs. Free entry into and exit from the market. The implications of these conditions are: a single market price is determined by the interaction of demand and supply firms earn zero economic profits in the long run. © 2017 by McGraw-Hill Education.

Sole seller of a good in a market gives that firm greater market power than if it competed against other firms. Implication: market demand curve is the monopolist’s demand curve.

Diseconomies of scale: exist whenever long-run average costs increase as output increases. Economies of scope: exist when the total cost of producing two products within the same firm is lower than when the products are produced by separate firms. Cost complementarity: exist when the marginal cost of producing one output is reduced when the output of another product is increased.

Thus, a supply curve exists in perfectly competitive markets. A monopolist’s market power implies .

Consider a monopolist producing output at two plants: The cost of producing units at plant 1 is , and the cost of producing at plant 2 is .

Each firm in the industry produces a differentiated product. There is free entry into and exit from the industry. A key difference between monopolistically competitive and perfectly competitive markets is that each firm produces a slightly differentiated product. Implication: products are close, but not perfect, substitutes; therefore, firm’s demand curve is downward sloping under monopolistic competition. © 2017 by McGraw-Hill Education.
