31. Which term best describes a market structure of limited competition in which the market is shared by a small number of sellers?
Answer: D
Oligopoly best describes a market structure of limited competition shared by a small number of sellers.
An oligopoly is characterized by a market dominated by a small number of firms, leading to limited competition. This structure often results in interdependent pricing and output decisions among the sellers.
A) Monopoly
A monopoly refers to a market structure where a single seller controls the entire market, leaving no competition. This is not applicable to the question, as it describes a scenario with only one seller rather than a small number of sellers.
B) Perfect competition
Perfect competition describes a market structure with many sellers and buyers, where no single seller can influence the market price. This option does not fit the criteria of limited competition among a small number of sellers.
C) Monopolistic competition
Monopolistic competition features many sellers offering differentiated products, allowing for some degree of market power. However, it still does not capture the essence of a market shared by a small number of sellers, as implied in the question.
D) Oligopoly
Oligopoly accurately describes a market structure where a few sellers dominate the market. These sellers have significant market power, and their decisions can greatly affect the overall market, making this option the most appropriate choice.
Conclusion
The term "oligopoly" is definitive in describing a market structure that involves limited competition among a small number of sellers. In contrast, monopoly, perfect competition, and monopolistic competition fail to capture the specific characteristics of limited competition among a few firms. Therefore, oligopoly is the correct answer, as it aligns perfectly with the question's requirements.
