想请问一下以下理解是不是对的

NO.PZ2016010801000037

问题如下:

In a perfect competitive market, a firm’s marginal revenue is always:

选项:

A.

equal to the price per unit.

B.

equal to the additional cost for one more unit.

C.

equal to the average cost per unit.

解释:

In a perfect competitive market, the firm is price taker, therefore, marginal revenue is always the same as price per unit. In equilibrium, each firm will reach the position where P=MR=MC.

考点:完全竞争市场

解析:在完全竞争的市场中,企业是价格接受者,因此边际收益始终等于单位价格。在均衡状态下,各企业才会达到P=MR=MC的均衡。

1.在perfect competition的情况下,p=ar=mr恒成立

2.在(1)的基础上,当perfect competition的市场达到均衡时,p=mr=mc=atc

1 个答案

嗨,从没放弃的小努力你好:


同学你好,书上的描述是

in short run ,p=ar=mr 一个企业达到均衡

long run p=mr=mc=atc perfect competition 达到均衡

虽然现在很辛苦,但努力过的感觉真的很好,加油!
