(1)画出供给和需求曲线来解释在实施价格控制之后两床位套间市场上的租金价格会怎样变动。
(2)你认为这一价格控制政策是否对所有的学生都是有利的？为什么是或为什么不是？
The city council of a small college town decides to regulate rents in order to reduce student living expenses. Suppose the average annual market - clearing rent for a two - bedroom apartment had been $ 700 per month and that rents were expected to increase to $ 900 within a year. The city council limits rents to their current S 700 - per - month level.
a. Draw a supply and demand graph to illustrate what will happen to the rental price of an apartment after the imposition of rent controls.
b. Do you think this policy will benefit all students？ Why or why not？
此题为判断题(对，错)。

第4题
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.

(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？

第8题
For thousands of years, people have known that the best way to understand a concept is to explain it to someone else. "While we teach, we learn," said Roman philosopher Seneca. Now scientists are bringing this ancient wisdom up-to-date. They're documenting why teaching is such a fruitful way to learn, and designing innovative ways for young people to engage in instruction. Researchers have found that students who sign up to tutor others work harder to understand the material, recall it more accurately and apply it more effectively. Student teachers score higher on tests than pupils who're learning only for their own sake. But how can children, still learning themselves, teach others？ One answer: They can tutor younger kids. Some studies have found that first-born children are more intelligent than their later-born siblings (兄弟姐妹). This suggests their higher IQs result from the time they spend teaching their siblings. Now educators are experimenting with ways to apply this model to academic subjects. They engage college undergraduates to teach computer science to high school students, who in turn instruct middle school students on the topic. But the most cutting-edge tool under development is the "teachable agent"—a computerized character who learns, tries, makes mistakes and asks questions just like a real-world pupil. Computer scientists have created an animated (动画的) figure called Betty's Brain, who has been "taught" about environmental science by hundreds of middle school students. Student teachers are motivated to help Betty master certain materials. While preparing to teach, they organize their knowledge and improve their own understanding. And as they explain the information to it, they identify problems in their own thinking. Feedback from the teachable agents further enhances the tutors' learning. The agents' questions compel student tutors to think and explain the materials in different ways, and watching the agent solve problems allows them to see their knowledge put into action. Above all, it's the emotions one experiences in teaching that facilitate learning. Student tutors feel upset when their teachable agents fail, but happy when these virtual pupils succeed as they derive pride and satisfaction from someone else's accomplishment. 1. What are researchers rediscovering through their studies？ A.Seneca's thinking is still applicable today. B.Better learners will become better teachers. C.Human intelligence tends to grow with age. D.Philosophical thinking improves instruction.
A、Seneca's thinking is still applicable today.
B、Better learners will become better teachers.
C、Human intelligence tends to grow with age.
D、Philosophical thinking improves instruction.
第9题
某公司的短期总成本函数由等式TC=200+55q给出，式中，TC为总成本; q为总产出数量;两者均以千计。
(1)该公司的固定成本是多少？
(2)如果该公司生产了100000单位的产品，它的平均可变成本是多少？
(3)其所生产的单位产品的边际成本是多少？
(4)其平均固定成本是多少？
(5)假定该公司通过贷款扩大生产规模，其固定成本增加5000美元，但其可变成本降至每1000单位产品45000美元，利率i也进入成本函数。利率每上升1%，成本增加3000美元。写出新的成本函数。
The short - run cost function of a company is given by the equation TC = 200 +55q, where TC is the total cost and q is the total quaintly of output ，both measured in thousands.
a. What is the company' s fixed cost？
b. If the company produced 100000 units of goods, what is its average variable cost？
c. What would be its marginal cost of production？
d. What would be its average fixed cost？
e. Suppose the company borrow money and expands its factory. Its fixed cost rises by
$ 50000, but its variable cost falls to $ 45000 per 1000 units. The cost of interest (i) also enters into the equation. Each one-point increase in the interest rate raises costs by $ 3000. Write the new cost equation.
