Consider a market in which a firm has monopoly power. Suppose in addition that the firm produces under the presence of either a positive or a negative extermality. Does the externality necessarily lead to a greater misallocation of resources？
W: Thank you.
M: A lot of young people are very nervous when they go to a job interview for the first time. What's the best way of dealing with this？
W: The obvious answer isn't much help, really, I'm afraid: "Just keep calm and do your best." If you're nervous to start with, this advice probably has the opposite effect. And in fact, a certain amount of tension is probably a good thing. It's the same with the way you sit when the inter viewer asks you to sit down.
M: How do you mean？
W: Well, if you balance on the edge of you chair, it shows you're nervous, but if you relax and make yourself too comfortable, that won't do, either. You should sit naturally, but straight, to show you're paying attention.
M: And I suppose you should face the interviewer when you answer questions.
W: Yes, eye contact is important then, but that doesn't mean you never take your eyes off the interviewer. And it's all right to be naturally pleasant, but don't try too hard.
M: One of the things that upset people most at interviews, I think, is that interviewers often ask trick questions. Even quite innocent questions like "How do you spend your spare time？" can contain traps in certain cases. Suppose the company would prefer an outdoor person but you spend every weekend looking at your stamp collection. What should you doe Should you always tell the truth or pretend to be what the company wants？
W: Tell the truth, yes, but not necessarily the whole truth. It's no good pre tending to be what you're not an experienced interviewer would soon find out but you needn't go out of your way to tell them anything you don't want them to know.
M: One last piece of advice before we sign off？
W: Yes, and it may surprise you. That is that very often young people get carried away just with the idea of winning. It's hard to remember when there's a lot of unemployment, as there is nowadays, but you should be sure that this is the kind of work you want to do and the firm is one that you would enjoy working for. Otherwise you may get the job and then find out that you hate it. So remember to ask sensibly questions as well as to answer sensibly.

(1)这笔费用将如何影响公司的固定成本、边际成本和平均成本？
(2)现假定该公司需支付一笔与其产量成比例的税费。那么，该费用又是如何影响公司的固定成本、边际成本以及平均成本的？
Suppose a firm must pay an annual tax, which is a fixed sum , independent of whether it produces any output.
a. How does this lax affect the firm 's fixed, marginal, and average costs？
b. Now suppose the firm is charged a lax that is proportional to the number of items it produces. Again, how does this tax affect the firm ' s fixed, marginal, and average costs？
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.
Look again at Figure 11. 16. Suppose the marginal costs c and C2 were zero. Show that in this case pure bundling is the most profitable pricing strategy , What price should be charged for the bundle, What will the firm's profit be？
(1)找出利润最大化时的L数量。
(2)找出利润最大化时的q数量。
(3)最大化利润是多少？
(4)假设现在每单位的产出要征税30美元，而每小时的劳动能得到15美元的补助。并且假设企业是价格接受者，所以产品价格保持150美元不变。找出新的利润最大化的L、q和利润。
(5)假设企业要为利润支付20%的税额。找出新的利润最大化的L、q和利润。

a. Find the profit - maximizing quantity of L.
b. Find the profit - maximizing quantity of q.
c. What is the maximum profit？
d. Suppose now that the firm is taxed $ 30 per unit of output and that the wage rate is subsidized at a rate of $ 15 per hour. Assume that the firm is a price taker, so the price of the product remains at $ 150. Find the new profit - maximizing levels of L, q, and profit.
e. Now suppose that the firm is required to pay a 20 percent lax on its profit. Find the new profit - maximizing levels of L, q, and profit.
