我们在例2.8讨论了近几年铜的全球需求的增加,部分归因于中国不断上升的消费。
(1)利用初始的需求弹性和供给弹性(诸如,ES=1.5且ED=-0.5),计算铜的需求增加20%对铜价的影响。
(2)计算该需求增加对均衡产量Q的影响。
(3)正如我们在例2.8中讨论的,美国铜产量在2000~2003年下降了。计算铜的需求增加20%(在1部分你做的)且铜的供给下降20 %对均衡价格和产量的影响。
In Example2. 8 (page 52), we discussed the recent increase in world demand for copper, due in part to China ' s rising consumption.
a. Using the original elasticities of demand and supply (i.e. Es=1.5 and ED=-0.5), calculate the effect of a 20 - percent increase in copper demand on the price of copper.
b. Now ealeulate the effect of this increase in demand on the equilibrium quantity, Q°.
c. As we discussed in Example 2. 8, the U. S. production of copper declined between 2000 and 2003. Calculate the effect on the equilibrium price and quantity of both a 20 - percent increase in copper demand (as you just did in part a) and of a 20 - percent decline in copper supply.
