这是一套关于微观经济学中垄断市场的一套原题，拜伦布朗教授根据平狄克教材亲自所编（共编写38套），被各国多所大学引用作为考试试题。平狄克的微观经济学在国内被视为考研教材，的确有一定难度。而这套题我与别人讨论过多次，都无法得出一个准确的答案。希望各位高手各抒己见，汇总出一个正确答案。（如果有哪位同学想考研，或想去美国读书，想要这38套试题作为练习题；或者哪位老师希望用来给学生做测试题，如果需要的话请留下邮箱地址或QQ，本人将会将38套英文原题发到你们邮箱里）
题目：（回答问题参考附件图片）
Set all variables to their baseline values. Make sure output is set to 20,000 hookups. Record the
values of these variables:
1) Market price
2) Average cost.
3) Profit per unit of output.
4) Total profit.
Keep output at 20,000 hookups.
5) What is the increase in cost due to one more hookup (MC)?
6) What's the added revenue from one more hookup (MR)?
7) If one more hookup is added, what's the change in profits?
8) At an output of 20,000, should the firm be producing more or less output? [Enter
more or less.]
Cable company management wants to know how to maximize total profit, and what price to set.
9) What's the profit maximizing output?
10) What's the profit maximizing price?
11) Continuing on from the last problem, what are total profits when profits are
maximized?
Cable company management expects consumer incomes to rise to $60,000. You must advise
them on what output to sell if the increase occurs.
12) What's the new profit maximizing output?
Continuing on from the last question, record the values of these variables after income rises:
13) Market price.
14) Total profits.
15A) Set all variables to their baseline values. You are visited by staff members from the
cable TV regulator's office. These are government officials and you must tell them
the truth about the firm's operation. Go on to 15B.
The government officials want to know what output will result in the socially best amount of
cable TV services.
15B) What's the socially best output?
16) What's the socially best price?
17) What are total profits when the socially best output and price are set?
The government regulators thank you for your help, but would like you to tell them how large a
subsidy the firm would need to produce the socially best output.
18) What per unit subsidy will be required?
19) What price would the firm WANT to charge if they actually received the subsidy?
