【正文】 Chapter 4 /The Market Forces of Supply and Demand v 287Chapter 4 The Market Forces of Supply and DemandTRUE/FALSE1. Prices allocate a market economy’s scarce resources.ANS: T DIF: 1 REF: 40NAT: Analytic LOC: Markets, market failure, and externalities TOP: Market economies MSC: Definitional2. In a market economy, supply and demand determine both the quantity of each good produced and the price at which it is sold.ANS: T DIF: 1 REF: 40NAT: Analytic LOC: Markets, market failure, and externalities TOP: Market economies MSC: Definitional3. A market is a group of buyers and sellers of a particular good or service.ANS: T DIF: 1 REF: 41NAT: Analytic LOC: Markets, market failure, and externalities TOP: Markets MSC: Definitional4. Sellers as a group determine the demand for a product, and buyers as a group determine the supply of a product.ANS: F DIF: 1 REF: 41NAT: Analytic LOC: Supply and demand TOP: Demand | SupplyMSC: Definitional5. A yard sale is an example of a market.ANS: T DIF: 2 REF: 41NAT: Analytic LOC: Markets, market failure, and externalities TOP: Markets MSC: Applicative6. A newspaper’s classified ads are an example of a market.ANS: T DIF: 2 REF: 41NAT: Analytic LOC: Markets, market failure, and externalities TOP: Markets MSC: Applicative7. Most markets in the economy are highly petitive.ANS: T DIF: 1 REF: 41NAT: Analytic LOC: Markets, market failure, and externalities TOP: Markets MSC: Definitional8. In a petitive market, the quantity of each good produced and the price at which it is sold are not determined by any single buyer or seller.ANS: T DIF: 1 REF: 41NAT: Analytic LOC: Markets, market failure, and externalities TOP: Competitive markets MSC: Definitional9. In a petitive market, there are so few buyers and so few sellers that each has a significant impact on the market price.ANS: F DIF: 1 REF: 41NAT: Analytic LOC: Markets, market failure, and externalities TOP: Competitive markets MSC: Definitional10. In a perfectly petitive market, the goods offered for sale are all exactly the same.ANS: T DIF: 1 REF: 41NAT: Analytic LOC: Perfect petition TOP: Perfect petitionMSC: Definitional11. In a perfectly petitive market, buyers and sellers are price setters.ANS: F DIF: 1 REF: 41NAT: Analytic LOC: Perfect petition TOP: Perfect petitionMSC: Definitional12. All goods and services are sold in perfectly petitive markets.ANS: F DIF: 1 REF: 41NAT: Analytic LOC: Perfect petition TOP: Perfect petitionMSC: Definitional13. If a good or service has only one seller, then the seller is called a monopoly.ANS: T DIF: 1 REF: 41NAT: Analytic LOC: Monopoly TOP: Monopoly MSC: Definitional14. Monopolists are price takers.ANS: F DIF: 2 REF: 41NAT: Analytic LOC: Monopoly TOP: Monopoly MSC: Interpretive15. Local cable TV panies frequently are monopolists.ANS: T DIF: 1 REF: 41NAT: Analytic LOC: Monopoly TOP: Monopoly MSC: Definitional16. The quantity demanded of a product is the amount that buyers are willing and able to purchase at a particular price.ANS: T DIF: 1 REF: 42NAT: Analytic LOC: Supply and demand TOP: Quantity demandedMSC: Definitional17. The law of demand is true for most goods in the economy.ANS: T DIF: 1 REF: 42NAT: Analytic LOC: Supply and demand TOP: Law of demandMSC: Definitional18. The law of demand states that, other things equal, when the price of a good rises, the quantity demanded of the good rises, and when the price falls, the quantity demanded falls.ANS: F DIF: 1 REF: 42NAT: Analytic LOC: Supply and demand TOP: Law of demandMSC: Definitional19. The demand curve is the upwardsloping line relating price and quantity demanded.ANS: F DIF: 1 REF: 42NAT: Analytic LOC: Supply and demand TOP: Demand curveMSC: Definitional20. Individual demand curves are summed horizontally to obtain the market demand curve.ANS: T DIF: 1 REF: 42NAT: Analytic LOC: Supply and demand TOP: Market demand curveMSC: Definitional21. The market demand curve shows how the total quantity demanded of a good varies as the ine of buyers varies, while all the other factors that affect how much consumers want to buy are held constant.ANS: F DIF: 1 REF: 42NAT: Analytic LOC: Supply and demand TOP: Market demand curveMSC: Definitional22. If something happens to alter the quantity demanded at any given price, then the demand curve shifts.ANS: T DIF: 1 REF: 42NAT: Analytic LOC: Supply and demand TOP: Demand curveMSC: Definitional23. A movement upward and to the left along a given demand curve is called a decrease in demand..ANS: F DIF: 2 REF: 42NAT: Analytic LOC: Supply and demand TOP: Demand curveMSC: Interpretive24. An increase in demand shifts the demand curve to the left.ANS: F DIF: 1 REF: 42NAT: Analytic LOC: Supply and demand TOP: Demand curveMSC: Definitional25. If the demand for a good falls when ine falls, then the good is called an inferior good.ANS: F DIF: 1 REF: 42NAT: Analytic LOC: Supply and demand TOP: Normal goodsMSC: Definitional26. When Mario39。s ine decreases, he buys more pasta. For Mario, pasta is a normal good.ANS: F DIF: 2 REF: 42NAT: Analytic LOC: Supply and demand TOP: Inferior goodsMSC: Applicative27. A decrease in ine will shift the demand curve for an inferior good to the right.ANS: T DIF: 2 REF: 42NAT: Analytic LOC: Supply and demand TOP: Inferior goodsMSC: Interpretive28. An increase in the price of a substitute good will shift the demand curve for a good to the right.ANS: T DIF: 2 REF: 42NAT: Analytic LOC: Supply and demand TOP: SubstitutesMSC: Interpretive29. Baseballs and baseball bats are substitute goods.ANS: F DIF: 2 REF: 42NAT: Analytic LOC: Supply and demand TOP: ComplementsMSC: Applicative30. A decrease in the price of a plement will shift the demand curve for a good to the left.ANS: F DIF: 2 REF: 42NAT:
