请问为什么不是perfect competition 谢谢?

NO.PZ2023010401000033

问题如下:

Which characteristic is a firm least likely to exhibit when it operates in a market with a downward sloping demand curve, many competitors, and zero economic profits in the long run?

选项:

A.Differentiated product

B.Low barriers to entry

C.No pricing power

解释:

The characteristics of monopolistic competition include a large number of competitors, low pricing power, and the production of differentiated products (through advertising and other non-price strategies), but these still result in some pricing power. The ease of entry results in zero economic profits in the long run.

嗨,爱思考的PZer你好:

Hello,亲爱的同学~

本题问:当一家公司在一个需求曲线向下倾斜(a downward sloping demand curve)、竞争对手众多、长期经济利润为零的市场中运营时,它最不可能表现出哪个特征?

根据题干描述,需求曲线向下倾斜、竞争对手众多、长期经济利润为零,是垄断竞争市场。


同学注意,这里不是完全竞争市场。

因为完全竞争市场的需求曲线,并不是题干中所描述的downward,而是Horizonal的。
