Answer: B Section: The Allocation of Scarce Resources Question Status: New AACSB: Application of knowledge For the following, please answer "ʺTrue"ʺ or "ʺFalse"ʺ and explain why. 14) Under most circumstances, the application of taxes on goods will only affect who gets the goods. Answer: False. Taxes will affect which goods are produced, how goods are produced, and who gets the goods. Section: The Allocation of Scarce Resources Question Status: Old AACSB: Analytic thinking 15) Most modern financial centers use computers to match buyers and sellers. This absence of personal contact contradicts the definition of a market. Answer: False. Buyers and sellers need not meet during a market transaction since a market is not tied to a particular location. Section: The Allocation of Scarce Resources Question Status: Old AACSB: Analytic thinking 16) Governments do not respond to prices. Answer: False. When products or services that governments purchase become more expensive, governments tend to purchase less of the products. For example, when the price of gasoline increased dramatically in the spring of 2006, the state of Georgia restricted the use of school buses. Section: The Allocation of Scarce Resources Question Status: Old AACSB: Analytic thinking 17) Explain how a market helps determine which goods and services will be produced, how to produce them, and who gets them. Answer: A market promotes interaction between consumers and firms. This interaction will result in prices, which influence the decisions of consumers and firms.

D) B and C Answer: A Section: Models Question Status: New AACSB: Application of knowledge For the following, please answer "ʺTrue"ʺ or "ʺFalse"ʺ and explain why. 17) Normative analysis offers decision makers the most valuable information when choosing among alternatives. Answer: False. Normative analysis states subjective goals but not how those goals can be achieved. To choose among alternatives decision maker uses positive analysis. Section: Models Question Status: Old AACSB: Analytic thinking 18) If a model fits reality but doesn'ʹt generate testable predictions, it is of little value to economists. Answer: True. If the model doesn'ʹt deliver testable predictions it cannot be tested against competing models. Section: Models Question Status: Old AACSB: Analytic thinking 19) If actual experience supports two competing theories, then both theories are proven to be true. Answer: False. Neither theory can be rejected but if they are competing, then the test is inconclusive. Section: Models Question Status: Old AACSB: Analytic thinking 20) Normative statements are easily debated whereas positive statements are simply rhetorical. Answer: False. Positive statements are not merely rhetorical. Rather, positive statements are testable statements. On the other hand, normative statements are not testable and therefore are often the most debated topics in society. Section: Models Question Status: Old AACSB: Analytic thinking 21) Legislators argue that a minimum wage law is instituted to help poor people. Economists can attack the minimum wage law on two fronts. First, some argue that government should not help the poor. Second, some argue that minimum wage laws actually hurt the poor because it creates unemployment. Which argument is normative and which is positive? Answer: An opinion about the role of government is a normative statement. An observation about the impact of a law is a positive statement.

Answer: D Section: Uses of Microeconomic Models Question Status: New AACSB: Analytic thinking For the following, please answer "ʺTrue"ʺ or "ʺFalse"ʺ and explain why. 10) Microeconomics can be used by governments to predict the impacts of a policy and suggest solutions to problems. Answer: True. Microeconomics models can be used to examine the effects of a policy, and can provide insight into possible solutions to economic problems. Section: Uses of Microeconomic Models Question Status: Old AACSB: Analytic thinking 11) One million automobiles have a defect that could cause the car to explode; however, only one of those cars will actually explode. Nobody knows which one car it is. When the car does explode, the victim'ʹs family will sue the automaker for $1 million and win. The defect costs $2 per car to repair. What does economics predict about the automaker'ʹs decision to repair the defect? Answer: Correcting the defect will cost $2 million. Not correcting the defect will only cost $1 million. Economics predicts that the automaker will not correct the defect. Section: Uses of Microeconomic Models Question Status: Old AACSB: Analytic thinking 12) Describe in words the anatomy of an economic model. Answer: An economic model is comprised of a set of assumptions that lead to a set of implications. In an effective economic model, if one or more of the assumptions are changed, so too is the set of implications. In other words, any assumption that does not influence the implications is superfluous and can be dropped from the model. In an effective economic model, the implications are clearly stated and testable using real-­‐‑world data.

B) shift rightward when the price of the good increases. C) slope downward. D) slope upward. Answer: C Section: Demand Question Status: Old AACSB: Analytic thinking 2) Assuming plasma TVs are a normal good, an increase in consumer incomes will lead to A) a rightward shift of the demand curve for plasma TVs. B) a movement upward along the demand curve for plasma TVs. C) a rightward shift of the supply curve for plasma TVs. D) no change of the demand curve for plasma TVs. Answer: A Section: Demand Question Status: Revised AACSB: Analytic thinking 3) Consider the demand function Qd = 150 -­‐‑ 2P.
