单项选择题
An analyst does research about perfect competition. In a perfect competition market, the market's demand curve is most likely()
A. less elasticthan a single firm's demand curve.
B. equally elastic as a single firm's demand curve.
C. more elastic than a single firm's demand curve.
答案
参考答案:A
解析:
完全竞争市场中,单个企业的需求线是平行线(弹性为无穷大),而市场的需求线是正常的向下倾斜的线(弹性大于零),价格需求弹性一般为负值,但这里所讲的大小,是讲它们的绝对值。所以,市场需求线比单个企业的需求线更没有弹性。
