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.

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 "True" or "False" 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't generate testable predictions, it is of little value to economists. Answer: True. If the model doesn't 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. Section: Models Question Status: Old AACSB: Analytic thinkin
