C nonresponsive. D zero. 131 Economists distinguish among the immediate market period, the short run, and the long run by noting that A supply is most elastic in the short run and least elastic in the immediate market period. B demand is most elastic in the long run and least elastic in the immediate market period. C supply is most elastic in the long run and least elastic in the immediate market period. D supply is most elastic in the short run and least elastic in the long run. The diagram indicates that A over range Q1 Q2 price elasticity of supply is greater for S1 than for S2. B over range Q1 Q2 price elasticity of supply is greater for S2 than for S1. C over range Q 1 Q 2 price elasticity of supply is the same for the two curves. D not enough information is given to compare price elasticities.
25 132 Use the figure below to answer the following question. 133 Use the figure below to answer the following question. Which graph shows the immediate market period for supply? A graph A B graph B C graph C D graph D For which graph is the supply perfectly inelastic? A graph A B graph B C graph C D graph D 134 The supply of cars will be more elastic the A greater the quantity demanded. B longer the time interval considered. C greater the decline in input prices. D less able producers are to make other goods. 135 To economists, the main differences between "the short run" and "the long run" are that A the law of diminishing returns applies in the long run, but not in the short run. B in the short run all resources are fixed, while in the long run all resources are variable. C fixed inputs are more important to decision making in the long run than they are in the short run. D in the long run all resources are variable, while in the short run at least one resource is fixed.
26 136 The main reason for the high price of antiques is that A supply is relatively elastic and demand increases over time. B supply is relatively inelastic and demand increases over time. C demand is relatively elastic and supply increases over time. D demand is relatively inelastic and supply increases over time. 137 The supply of product X is perfectly inelastic if the price of X rises by A 5% and quantity supplied rises by 7%. B 8% and quantity supplied rises by 8%. C 10% and quantity supplied stays the same. D 7% and quantity supplied rises by 5%. 138 It takes a considerable amount of time to increase the production of pork. This implies that A a change in the demand for pork will not affect its price in the short run. B the shortrun supply curve for pork is less elastic than the longrun supply curve for pork. C an increase in the demand for pork will elicit a larger supply response in the short run than in the long run. D the longrun supply curve for pork is less elastic than the shortrun supply curve for pork. 139 Use the figure below to answer the following question. 140 Use the figure below to answer the following question. The diagram concerns supply adjustments to an increase in demand (D 1 to D 2 ) in the immediate market period, the short run, and the long run. In the immediate market period, the increase in demand will A have no effect on either equilibrium price or quantity. B increase equilibrium price but not equilibrium quantity. C increase equilibrium quantity but not equilibrium price. D increase both equilibrium price and quantity. 141 Use the figure below to answer the following question. The diagram concerns supply adjustments to an increase in demand (D1 to D2 ) in the immediate market period, the short run, and the long run. Supply curves S1, S2, and S3 apply to the A immediate market period, long run, and short run respectively. B immediate market period, short run, and long run respectively. C long run, short run, and immediate market period respectively. D short run, long run, and immediate market period respectively. The diagram concerns supply adjustments to an increase in demand (D1 to D2 ) in the immediate market period, the short run, and the long run. In the long run, the increase in demand will A have no effect on either equilibrium price or quantity. B increase equilibrium price but not equilibrium quantity. C increase equilibrium quantity but not equilibrium price. D increase both equilibrium price and quantity.
27 142 Use the figure below to answer the following question. The diagram concerns supply adjustments to an increase in demand (D1 to D2) in the immediate market period, the short run, and the long run. On the basis of this illustration, we can conclude that A shortrun adjustments are more economically efficient than are longrun adjustments. B the amount of time producers have to adjust to a change in demand is not a determinant of supply elasticity. C supply is more elastic the greater the amount of time producers have to adjust to a change in demand. D supply is less elastic the greater the amount of time producers have to adjust to a change in demand.
