2. Monopolists will operate according to the government's maximum price. At this time, although it is not certain to get the maximum profit at MR=MC, as long as it is greater than AC, there will always be profits.

(2) The sales prices of some agricultural means of production and industrial consumer goods that enjoy financial subsidies are sold by commercial departments in remote areas, and enterprises can only implement price limits and have no right to change them. This is a form of state price. (3) In international trade, the highest price allowed by the government of the importing country for certain commodities.

The price ceiling refers to the government's stipulation that the price of a certain product or service should not exceed a certain level, such as the price of a certain medical service should not exceed that of 80 yuan.

If the original market price of a medical service is 100 yuan each time, then the regulation that the price does not exceed 120 yuan will not work, because the price will not exceed 65,438 yuan. ....
