问题如下：
The short-term shutdown point of production for a firm operating under perfect competition will most likely occur when:
选项：
A.price is equal to average total cost.
B.marginal revenue is equal to marginal cost.
C.marginal revenue is less than average variable costs.
解释：
C is correct.
The firm should shut down production when marginal revenue is less than average variable cost.
考点：停止营业点
解析：当边际收益小于平均可变成本时，厂商就应该停止营业。所以应该选C
你好，shutdown point 是TR“=”TVC时哇，小于就是直接关闭了

NO.PZ2016010802000047 老师您好，能不能用公式的方法推一下这个C的呢~？我只能从意思方面做出来。
请问A为什么不对 是应该等于AVC吗
marginrevenue is equto margincost. marginrevenue is less thaverage variable costs. C is correct. The firm shoulshut wn proction when marginrevenue is less thaverage variable cost. 考点停止营业点 解析当边际收益小于平均可变成本时，厂商就应该停止营业。所以应该选C请问为啥不选A，price等于ATC的时候不就是shutwn point点么
