问题如下:
In a perfectly competitive market, If one supplier reduces its output by 5% and wants to increase price by 5% then:
选项:
A.his total revenue will reduce by 5%.
B.his average revenue will reduce by 5%.
C.his total revenue will reduce by less than 5%.
解释:
A is correct.
The unit sales change of a single supplier in a perfectly competitive market has no influence on the market price. Thus, a reduce of 5% in output will reduce the revenue at 5% as well.
考点:完全竞争市场下厂商的总收入
解析:在完全竞争的市场条件下,P=MR
虽然题目中的厂商把单位售价提高5%,但是农场品市场是完全竞争市场,厂家只是价格的被动接受者。到最后改厂商只能以原价格卖出产品。但是产量减少了5%,所以总收入减少了5%。B,C选项说法都不对。
为什么不是average revenue减少百分之5呀
