一家企业的固定生产成本为5000美元,边际生产成本为常数,为500美元/单位产品。
(1)企业的总成本函数是什么?平均成本呢?
(2)如果企业想使其平均总成本最低,它应该选择非常大的产量还是比较小的产量?解释你的结论。
A firm has a fixed production cost of $ 5000 and a constant marginal cost of production of S 500 per unit produced.
a. What is the firm' s total cost function? Average cost?
b. If the firm wanted to minimize the average total cost,would it choose to be very large or very small? Explain.

下表显示了一个以常数边际成本10美元生产的垄断者面临的需求曲线。
(1)计算该厂商的边际收益曲线。
(2)该厂商的利润最大化产量和价格是多少?该厂商的利润为多少?
(3)在一竞争性行业中均衡价格和数量各为多少?
(4)如果该垄断者被迫以完全竞争的均衡价格生产,社会得益是什么?结果是谁获益谁受损?
The following table shows the demand curve facing a monopolist who produces at a constant marginal cost of $ 10.
a. Calculate the firm' s marginal revenue curve.
b. What are the firm's profit - maximizing output and price? What is its profit?
c. What would the equilibrium price and quantity be in a competitive industry?
d. What would the social gain be if this monopolist were forced to produce and price at the competitive equilibrium? Who would gain and lose as a result?
A.息税前利润=(单价-单位变动成本)×销售量
B.边际贡献=销售收入-变动成本
C.利润=边际贡献-固定成本
D.边际贡献率+变动成本率=1
If a firm enjoys economies of scale up to a certain output level, and cost then increases proportionately with output, what can you say about the shape of the long -run average cost curve?
