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?

第11题
(1)假设某厂商的产量函数为q=9x1/2,在短期,固定成本为1000美元,x为可变投入,其成本为4000美元/单位。生产q单位产品的总成本为多少?[即求出总成本函数C(q)]
(2)写出供给曲线方程。
(3)如果价格为1000美元,厂商产量为多少?利润水平为多少?在成本曲线图上表示出你的结论。
a. Suppose that a firm's production function is q=9x1/2in the short nun, where there are fixed costs of $ 1000, and x is the variable input whose cost is S 4000 per unit. What is the total cost of producing a level o[ output q? In other words, identify the total cost function C(q)?
b. Write down the equation for the supply curve.
e. If price is $ 1000, how many units will the firm produce? What is the level of profit? Illustrate your answer on a cost - curve graph.
