能否解释一下normalcost和 economic cost的区别 为什么定价在ATC上刚好可以收到normalcost呀

问题如下：

Which of the following is the more common form of regulation to force the monopolists reduce price?

选项：

A.

Set a definite price.

B.

Use marginal cost pricing.

C.

Use average cost pricing.

解释：

Average cost pricing is the most common form of regulation. It forces a monopolist to reduce price to where the firm’s ATC is equal to market demand.

考点：垄断下的监管。

解析：平均成本定价是最常见的监管形式。它迫使垄断者将价格降低到公司的ATC等于市场需求的水平。该水平上，企业既不会获取超额利润，也不会破产亏损。
