问题如下:
Under conditions of perfect competition, in the long run firms will most likely earn:
选项:
A.normal profits.
B.positive economic profits.
C.negative economic profits.
解释:
A is correct.
Competition should drive prices down to long-run marginal cost, resulting in only normal profits being earned.
考点:正常利润。
解析:在完全竞争的市场条件下,厂商的利润为正常利润,即经济利润为0。
因为如果经济利润大于0,那么会有更多的厂商进入该市场瓜分利润,从而让经济利润降低为0.
如果经济利润小于0,那么现在市场中的厂商会退出市场,供给减少,价格增加从而使得留下的那些厂商的经济利润由负数上升到0.
完全竞争下的厂商 长期时只获得正常利润,
可是正常利润不是只补偿了企业家才能么,
但是货物本身也是有成本的,如果只是经济利润=0,相当于只有企业家才能被补偿了,那企业活不下去啊
