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
- 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.
- 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.

A不正确, 因为在寡头垄断市场中存在共谋，个体生产参与者共同瓜分总市场需求曲线。然而，即使在非串通的市场条件下，每个公司仍然面临着基于自己定价和产出决策的个人需求曲线。
B正确,因为在寡头垄断市场中，无论是否存在合谋，每家公司都面临着各自的需求曲线。在非串通的市场条件下，企业根据各自的需求曲线独立地决定它们的定价和产出水平。
C不正确,因为在寡头垄断市场中存在共谋，个体生产参与者共同瓜分总市场需求曲线。然而，即使在非串通的市场条件下，每个公司仍然面临着基于自己定价和产出决策的个人需求曲线。
选项B的解释里第一句话不就是印证了C选项是正确的吗？
“B正确,因为在寡头垄断市场中，无论是否存在合谋，每家公司都面临着各自的需求曲线。”
