问题如下:
QuestionIf a firm encounters numerous competitors, a downward-sloping demand
curve for its products, and zero economic profits in the long run, which
characteristic is it least likely to possess?
选项:
A.No pricing power B.Low barriers to entry C.Differentiated product解释:
Solution
-
In the context of monopolistic competition, firms encounter many competitors and generally have limited pricing power due to the downward-sloping demand curve. While they may offer differentiated products through advertising and non-price strategies, they still maintain some level of pricing power. However, the ease of entry into the market results in zero economic profits in the long run
- Incorrect. "Low barriers to entry"&"Product differentiation" are characteristics of monopolistic competition.
• describe characteristics of perfect competition, monopolistic competition, oligopoly, and pure monopoly
在垄断竞争的情况下,由于需求曲线向下倾斜,企业遇到许多竞争者,通常具有有限的定价权。虽然他们可能会通过广告和非价格策略提供差异化的产品,但他们仍然保持一定程度的定价权。然而,从长远来看,进入市场的方便性导致经济利润为零
不正确的。“低进入门槛”和“产品差异化”是垄断竞争的特征。
“低进入门槛”和“产品差异化”则是垄断竞争的特征。
其他答案看到:
本题先给出几个特征: numerous competitors、 a downward-sloping demand curve for its products、zero economic profits in the long run。
这是垄断竞争市场。
如果是完全竞争,则需求曲线是horizon,而不是题目给出的downward sloping。
完全竞争的需求曲线对个体来说才是horizon,对整个市场来说不也是downward吗?
