Question 37

Key features of an oligopoly include the actions of any one seller significantly impacting other sellers, a limited number of sellers, and interdependence among firms.

In an oligopoly, the market is characterized by few sellers, where the decisions made by one firm can influence the market dynamics and profitability of others, showcasing a high level of interdependence.

A) The actions of any one seller in the market can have a large impact on the profits of all the other sellers.

This statement is correct as it highlights a fundamental characteristic of oligopolistic markets. Since there are few firms, any strategic move, such as price changes or product launches, by one seller can directly affect the profits and strategies of the remaining sellers.

B) There are a few sellers.

This option accurately describes oligopoly as one of its defining features. In an oligopolistic market, the presence of only a small number of sellers leads to a concentrated market structure where each firm holds significant market power.

C) There is little if any motivation for cooperation between firms.

This statement is incorrect. While firms in an oligopoly may compete fiercely, there is often a motivation to cooperate, particularly in terms of price setting and market sharing, to maximize their collective profits, which is contrary to the essence of this option.

D) Firms in an oligopoly are interdependent in a way that competitive firms are not.

This option is correct, as it emphasizes the unique nature of oligopolistic firms' interdependence. Unlike firms in competitive markets, which operate independently, oligopolistic firms must consider the potential reactions of their rivals when making decisions, leading to strategic behavior.

E) firms in oligopoly are independent of one another, much like competitive firms

This statement is incorrect. It contradicts the very nature of oligopoly, where firms are dependent on each other's actions. In a competitive market, firms operate independently, while oligopolists must account for the behavior of their few rivals.

F) the actions of any one seller in the market have little, if any impact on the profits of all the other sellers

This option is incorrect. It misrepresents the dynamics of an oligopoly, where the actions of one seller can significantly affect the profitability of others, due to their interdependent nature.

Conclusion

The correct answers—A, B, and D—accurately reflect the essential characteristics of an oligopoly, emphasizing the limited number of sellers, the significant impact of one seller on others, and the interdependence among firms. Options C, E, and F fail to recognize the strategic interactions and motivations inherent in oligopolistic markets, thus affirming the correctness of the chosen answers.
