问题如下:
In which market structure, advertising is least likely to be used for differentiation promotion?
选项:
A.monopolistic competition.
B.perfect competition.
C.oligopoly.
解释:
B is correct
In a market of perfect competition, the products are identical, thus there is no reason for advertising.
考点:市场结构
解析:完全竞争市场,产品都是同质的,没有差异,厂商通过广告宣传只会徒劳增加成本,所以B入选。
寡头以及垄断竞争市场上厂商生产的产品有一定的差异,所以厂家可以通过广告提高市场占有率,增加利润。
请问monopoly情境下的公司数量一定限制于1吗,very few也不可以吗
