单选题 An analyst does research about Nash Equilibrium. With respect to game theory, which of the following describes the condition that two colluding firms in an oligopoly market are a Nash Equilibrium?
A. Neither firm cheats.
B. Only one firm cheats.
C. Both firm cheat.

【正确答案】 C
【答案解析】[解析] 纳什均衡(Nash Equilibrium)是指寡头企业最终达到的均衡。市场中,两个寡头企业希望通过勾结来获得行业的最大经济利润,但其中一个寡头企业可能会违反协议增加产量,以增加其自身的经济利润,而另一个寡头企业有可能发生经济亏损,但如果每个企业都违反协议,则最终会达到一种均衡。
