问题如下:
In a market of perfect competition, if economic profits are accessible to companies. In the long run, the supply curve is most likely to:
选项:
A.stay the same.
B.shift to the right.
C.shift to the left.
解释:
B is correct
New competitors will be attracted to the market by economic profits, and the existing companies will be encouraged to expand production.
考点:完全竞争市场
解析:由于存在不菲的利润,所以这些利润会吸引外部的厂商进入该市场分一杯羹,同时原有厂商也会进一步扩大生产,两者都会导致行业供给增加,供给曲线向右平移。
您好,不是很理解解析,能否画图详细解释一下?
