中级微观经济学题目
The United States imports about half of its petroleum needs.Suppose that the rest of the oil producers are willing to supply as much oil as the United States wants at a constant price of $25 a barrel.What would happen to the price of domestic oil if a tax of $5 a barrel were placed on foreign oil?

答案

楼主是需要英译中么?
美国近一半的石油需求依靠进口.假设,国外石油生产商愿意以每桶25美元的固定价格向美国提供石油,以满足它的需求.问：如果对每桶进口石油增收5美元的税,国内油价会如何变化?
以common sense判断的话,国内油价应该上升吧.因为国外油价贵了,对进口石油需求可能减少,而国内石油需求增加.供小于求,则价格上升.仅供参考哈~
