CHAPTER ONE ECONOMICS AND ECONOMIC REASONING PROBLEM SET 1. Briefly point out the faulty reasoning in each of the following situations: (LO2) a. You win a free, nontransferable ticket to a Taylor Swift concert. Since the ticket is free and it will therefore cost you nothing to go, you decide to go to the concert. b. You paid nonrefundable tuition of $3,000 to take a 15-week course. Therefore, the opportunity cost of attending class each week is $3,000 divided by 15, or $200. c. You like to avoid costs; every decision involves opportunity cost. So you don’t make decisions. d. You have purchased 5 premium apples for $1.99 a pound, but when you get home, you discover they are mushy. Since you paid top dollar for these apples, you decide you have to eat them. 2. Classify the following Wall Street Journal articles as involving macroeconomic or microeconomic issues based on their titles: (LO1) a. “Jerome Powell Affirms Fed’s Patient Approach to Future Interest Rate Charges” b. “How Drugs for Rare Diseases Became Lifeline for Companies” c. “Monetary Tightening Damps Brazil Investment” d. “Debut of Chicken Little Gives Disney Something to Crow Over” 1 © 2020 by McGraw-Hill Education.

Identify the following statements as examples of positive economics, normative economics, or the art of economics: (LO5) a. The Federal government needs to raise the minimum wage to $8 per hour so that families will have sufficient income to meet their basic needs. b. A country’s overall income is more important than how that income is distributed. c. One in four workers today has no access to employment-based family health coverage. d. To reduce income inequality in the U.S., we could increase the earned-income tax credit. e. It is the federal government’s responsibility to assure health coverage for all families. 4. Briefly explain why the following statements are either TRUE or FALSE: (LO3) a. Even though school dormitory rooms are rationed by lottery, these rooms are still affected by economic forces. b. Because the U.S. postal service is a monopoly and Congress sets postal prices through legislation, market forces do not determine stamp prices. c. New York City government auctions taxi medallions that give the right to transport passengers by taxi. Because the government controls the number of medallions, market forces do not determine their price. 2 © 2020 by McGraw-Hill Education.

The cost is the benefit you would have received from another activity, or opportunity cost. b. Since the tuition is nonrefundable, it is a sunk cost and therefore no longer represents opportunity costs. The true opportunities costs of continuing to take the course are the benefit of doing something else during class time. c. Deciding not to make decisions is still a decision. The opportunity cost of not considering choices is the benefit you would have gained from making those choices. d. How much you paid for the apples is a sunk cost, and therefore is not relevant. 2. a. Macroeconomics b. Microeconomics c. Macroeconomics d. Microeconomics 3. a. Normative b. Normative c. Positive d. Art of economics e. Normative 4. a. True. Economic forces always operate. b. True. Political forces, not market forces determine stamp prices. c. False. Even though the government regulates this market, because the medallions are sold at an auction, market forces determine their prices. 3 © 2020 by McGraw-Hill Education.

One way for the United States to regain a comparative advantage in the production of goods is for the U.S. exchange rate to decline. b. Trade restrictions facilitate the impact of the law of one price on wages and prices internationally. c. Wages in China are lower than in the United States.

Answers to the Problem Set The following are the correct answers to the problem set along with the learning objective(s) associated with each question. 1. a. Decreasing butter production by 3 from 12 to 9 pounds. b. Decreasing butter production by 4 from 9 to 5 pounds. c. Opportunity costs of producing guns increase as more guns are produced. This is called the principle of increasing marginal opportunity cost. 2. a. It would shift in along the axis labeled “agricultural goods.” b. It would shift out along the axis labeled “manufacturing goods.” c. It would shift in along both axes. 3. a. See graph. b. See graph. c. See graph. d. Point B is inefficient because it is inside the production possibility curve. One could increase the number of guns while still produce the same amount of butter, or vice versa. 10 9 8 A C 7 Butter 6 5 B 4 3 2 1 0 0 1 2 3 4 5 6 7 8 9 10 Guns 4.

True. If the U.S. exchange rate falls, the dollar value of foreign wages will rise. That is, the relative wages of U.S. workers will decline, which will help the U.S. regain its comparative advantage. b. False. Because trade restrictions restrict the flow of goods and services, they keep the law of one price from equalizing wages and prices internationally. c. False. A country that has a comparative advantage in producing one set of goods means that the other country has to have a comparative advantage in the other set of goods. 4 © 2020 by McGraw-Hill Education.

Not authorized for sale or distribution in any manner. This document may not be copied, scanned, duplicated, forwarded, distributed, or posted on a website, in whole or part. a. Equilibrium price is $9.50 and equilibrium quantity is 12 pizzas. b. At a price of $8.00, there would be excess demand of 24 pizzas; at a price of $10.00, there would be excess supply of 12 pizzas. c. If the price were $9.00, there would be pressure on the price to rise because of the excess demand. 4. a. Equilibrium price rises, and equilibrium quantity declines. b. Equilibrium price declines, and equilibrium quantity rises. c. Equilibrium quantity rises. The effect on equilibrium price is unknown. d. Equilibrium quantity declines. The effect on equilibrium price is unknown. 5. The fallacy of composition is the false assumption that what is true for a part will also be true for the whole. Supply and demand analysis assumes that other things remain constant. The fallacy of composition reminds us that the larger the market under consideration, the more likely it is that other things will change when this market changes, so that actual observed changes in the market will differ from what the simple supply and demand analysis would suggest. 4 © 2020 by McGraw-Hill Education.
