为什么在合谋的情况下不需要面对自己的需求曲线

  1. CFA I
  2. Economics Analysis

NO.PZ2023071902000071

问题如下：

QuestionIn an oligopoly market, each firm faces an individual demand curve under:

选项：

A.colluding market conditions only. B.non-colluding market conditions only. C.both colluding and non-colluding market conditions.

解释：

Solution

  1. Incorrect because in an oligopoly market where collusion is present, the individual production participants collectively divide the aggregate market demand curve. However, even under non-colluding market conditions, each firm still faces an individual demand curve based on its own pricing and output decisions.
  2. Correct because in an oligopoly market, each firm faces an individual demand curve regardless of whether collusion is present or not. Under non-colluding market conditions, firms independently determine their pricing and output levels based on their individual demand curves.
  3. Incorrect because in an oligopoly market where collusion is present, the individual production participants collectively divide the aggregate market demand curve. However, even under non-colluding market conditions, each firm still faces an individual demand curve based on its own pricing and output decisions.

我理解：即使在合谋的情况下，每个企业仍然面对其自己的需求曲线，这取决于其独立的定价和产量决策，以及市场对这些决策的反应。

嗨，努力学习的PZer你好：

Hello，亲爱的同学~

同学对现实的观察还是比较细微的。

现实中，绝对的不需要面临自己的需求曲线，确实也很难出现。

因为即使合谋了，各家也都有自己的小心思。


只是CFA这里，理论上，既然合谋了，那么几个企业就组成攻守同盟了，视作一家了。

这是经济学理论的假设问题。经济学理论和现实，是可以不一致的。

只是考试的时候，同学还是要遵循CFA原版书提供的知识点来解题。
