1.  1) Use the price mechanism\

2.  So, in order to get the perfect allocation, the government must implement microeconomic policies to make up.

3.  When confronting with severe market failure, our government should clear the way for varieties of information, implement the policy of price control and organize the public purchase to deal with the recession.

4.  However, universities need to take many factors into account when implementing this policy.

5.  If the university can implement the policy in this way, I'm sure we do will benefit from it.

6.  How to implement this policy?

7.  It is not only the cost of employing the panel special for answering people's complaining and questioning, but also the time which the governments cost to balance people's requirement and their initial schedule to implement a certain policy.

8.  If every university implement the policy, most university students will become masters of many different fields, which makes a contribution in our country's development.

9.  But to implement the policy, there still remain a lot of problems.

10.  As far as I can see, once the policy is implemented, even if students show no objection to it, they will regard taking the courses as finishing tasks instead of learning new knowledge.
