A binding price ceiling may not help all consumers, but it does not hurt any consumers.ANS: F DIF: 2 REF: 6-1NAT: Analytic LOC: Supply and demand TOP: Price ceilings MSC: Interpretive26. When the government imposes a binding price ceiling ona competitive market, a surplus of the good arises,and sellers must ration the scarce goods among the large number of potential buyers.ANS: F DIF: 1 REF: 6-1NAT: Analytic LOC: Supply and demand TOP: Price ceilings | ShortagesMSC: Definitional27. The rationing mechanisms that develop under binding price ceilings are usually inefficient.ANS: T DIF: 2 REF: 6-1NAT: Analytic LOC: Supply and demand TOP: Price ceilings | EfficiencyMSC: Interpretive28.

When a free market for a good reaches equilibrium, anyone who is willing and able to pay the market price can buy the good.ANS: T DIF: 2 REF: 6-1NAT: Analytic LOC: Supply and demand TOP: PricesMSC: Interpretive32. If a price ceiling of $2 per gallon is imposed on gasoline, and the market equilibrium price is $1.50, then theprice ceiling is a binding constraint on the market.ANS: F DIF: 2 REF: 6-1NAT: Analytic LOC: Supply and demand TOP: Price ceilings MSC: Applicative33. If a price ceiling of $1.50 per gallon is imposed on gasoline, and the market equilibrium price is $2, then theprice ceiling is a binding constraint on the market.ANS: T DIF: 2 REF: 6-1NAT: Analytic LOC: Supply and demand TOP: Price ceilings MSC: Applicative374 Chapter 6/Supply, Demand, and Government Policies34. A price ceiling caused the gasoline shortage of 1973 in the United States.ANS: T DIF: 2 REF: 6-1NAT: Analytic LOC: Supply and demand TOP: Price ceilings MSC: Interpretive35. One common example of a price ceiling is rent control.ANS: T DIF: 1 REF: 6-1NAT: Analytic LOC: Supply and demand TOP: Rent controlMSC: Definitional36. The goal of rent control is to help the poor by making housing more affordable.ANS: T DIF: 1 REF: 6-1NAT: Analytic LOC: Supply and demand TOP: Rent controlMSC: Definitional37. Economists argue that rent control is a highly efficient way to help the poor raise their standard of living. ANS: F DIF: 2 REF: 6-1NAT: Analytic LOC: The study of economics and definitions of economicsTOP: Economists | Rent control MSC: Interpretive38. Because supply and demand are inelastic in the short run, the initial shortage caused by rent control is large. ANS: F DIF: 1 REF: 6-1NAT: Analytic LOC: Supply and demand TOP: Rent control | Elasticity MSC: Definitional39. The primary effect of rent control in the short run is to reduce rents.ANS: T DIF: 1 REF: 6-1NAT: Analytic LOC: Supply and demand TOP: Rent controlMSC: Definitional40. The housing shortages caused by rent control are larger in the long run than in the short run because both the supply of housing and the demand for housing are more elastic in the long run.ANS: T DIF: 2 REF: 6-1NAT: Analytic LOC: Supply and demand TOP: Rent control | ElasticityMSC: Interpretive41.
