假设一个利润最大化的垄断者的生产产出为800单位，并索取每单位40美元的价格。

(1)如果产品的需求弹性为-2,求生产最后一单位产品的边际成本。

(2)厂商边际成本上的百分比价格加成为多少？

(3)假设生产最后一单位产品的平均成本为15美元，且厂商的固定成本为2000美元。求厂商的利润。

Suppose a profit - maximizing monopolist is producing 800 units of output and is charging a price of $ 40 per unit.

a. If the elasticity of demand for the product is - 2, find the marginal cost of the last unit produced.

b. What is the firm ' s percentage markup of price over marginal cost？

c. Suppose that the average cost of the last unit produced is $ I5 and the firm' s fixed cost is $ 2000. Find the firm' s profit.

下表给出了一家厂商的单位产品销售价格(单位:美元)和总成本的信息，

(1)填充表中空格。

(2)如果价格从60美元下降到50美元，企业的产量选择和利润将如何变化？

The data in the following table give information about the price (in total ) for which a firm can sell a unit of output and the total cost of production.

a.Fill the blanks in the table.

b.Show what happens to the firm' s output choice and profit if the price of the product falls from$60 to $50.

(1)企业目前的产量为100单位，成本最小化的劳动和资本分别为20和5。在图上用等产量线和等成本线表示出来。

(2)企业想将产量扩大为140单位，如果资本在短期固定，需要多少劳动？在图形上表示出来，并计算企业新的成本。

(3)在图形上表示出企业在长期生产140单位产品的成本最小化劳动和资本投入。

(4)如果边际技术替代率为K/L,计算生产140单位产品的最优劳动和资本投入。

Suppose that a firm' s production is q= 10L1/2K1/2. The cost of a unit of labor is $ 20 and the cost of a unit of capital is $ 80. a The firm is currently production 100 unis of output and has determined that the cost - mini-mizing quantities of labor and capital are 20 and 5, respectively. Graphically illustrate this using isoquants and isocost lines.

b，The firm now wants to increase output to 140 units. If capital is fixed in the short run, how much labor will the firm require？ Illustrator this graphically and find the firms new total cost.

c. Graphically identify the cost - minimizing level of capital and labor in the long run if the firm wants to produce 140 units.

d. If the marginal rate of technical substitution is K/L, find the optimal level of capital and labor required to produce the 140 units of output.
