第4题
假设某一特殊行业的信息如下:
QD=6500-100P市场需求
QS=1200P市场供给
C(q)=722+q2/200厂商总成本
MC(q)=2q/200
厂商边际成本
假定所有厂商完全同质，而且市场是完全竞争的。
(1)计算均衡价格、均衡产量、厂商供给产量和每家厂商的利润。
(2)在长期将有厂商进入还是退出市场？试解释。进入或退出将会对市场产生何种影响？
(3)在长期，每家企业销售其产品的最低价格为多少？利润是正的、负的还是为零？解释你的结论。
(4)在短期，每家企业销售其产品的最低价格为多少？利润是正的、负的还是为零？解释你的结论。
Suppose you are give the following information about a particular industry:
QD=6500-100P Market demand
QS=1200P Market supply
C(q)=722+q2/200 Firm total cost function
MC(q)=2q/200 Firm marginal cost function
Assume that all firms are identical and that the market is characterized by pure competition.
a. Find the equilibrium price, the equilibrium quantity, the output supplied by the firm, and the profit of each firm.
b. Would you expect to see entry into or exit from the industry in the long run？ Explain. What effect will entry or exit have on market equilibrium？
e. What is the lowest price at which each firm would sell its output in the long run？ Is profit positive, negative, or zero at this price？ Explain.
d. What is the lowest price at which each firm would sell its output in the short run？ Is profit positive, negative, or zero at this price？ Explain.

第6题
，n为市场上厂商的数量。设美国和欧洲市场上分别有3亿和5.33亿人口。a.在没有对外贸易时，美国和欧洲汽车市场上均衡的厂商数量是多少？
b.在没有对外贸易时，美国和欧洲汽车市场上均衡的价格是多少？
c.现在假设美欧之间进行自由贸易，美国市场上除了原有的3亿人口外，将增加5.33亿人口。在美国和欧洲汽车市场上将有多少汽车厂商？汽车新的均衡价格是多少？
d.美国市场上汽车的价格在b和c中为何不同？自由贸易改善了消费者的福利吗？是怎样改善的？
Suppose that fixed costs for a firm in the automobile industry (start- up costs of factories， capital equipment， and so on) are $5 billion and that variable costs are equal to $17，000 per finished automobile. Because more firms increase competition in the market， the market price falls as more firms enter an automobile market， or specifically， where n represents the number of firms in a market. Assume that the initial size of the U.S. and the European automobile markets are 300 million and 533 million people， respectively.
a.Calculate the equilibrium number of firms in the U.S. and European automobile markets without trade.
b.What is the equilibrium price of automobiles in the United States and Europe if the automobile industry is closed to foreign trade？
c.Now suppose that the United States decides on free trade in automobiles with Europe. The trade agreement with the Europeans adds 533 million consumers to the automobile market， in addition to the 300 million in the United States. How many automobile firms will there be in the United States and in Europe combined？ What will be the new equilibrium price of automobiles？
d.Why are prices in the United States different in (c) than in (b) ？ Are consumers better off with free trade？ In what ways？
