Question 37

Key features of an oligopoly include interdependence among firms, a limited number of sellers, and the significant impact of one seller's actions on others.

Oligopolies are characterized by a small number of firms that dominate the market, which means that the actions of any one seller can significantly affect the profits and strategies of the others. This interdependence among firms is a defining feature of oligopolies.

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 accurately reflects a fundamental characteristic of oligopolies, where the interdependence of firms means that decisions made by one seller can influence the financial outcomes of others in the market. This creates a strategic environment where firms must consider the potential reactions of their competitors.

B) There are a few sellers.

This option is correct as oligopolies consist of a limited number of firms, which is essential for the market structure. The small number of sellers allows for a concentration of market power and makes the competitive dynamic unique compared to markets with many sellers.

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

This statement is incorrect in the context of oligopolies. In fact, firms often have a motivation for cooperation, such as forming cartels or engaging in tacit collusion to maximize joint profits. Thus, the motivation for cooperation exists, contrary to what this option implies.

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

This option is correct, as the interdependence among firms in an oligopoly involves strategic decision-making that is influenced by the actions of competitors. Unlike in perfect competition, where firms operate independently, oligopolistic firms must carefully consider each other's potential responses to their actions.

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

This statement is incorrect because it contradicts the essence of an oligopoly. Firms in an oligopoly are not independent; rather, their decisions are interlinked, and they must account for the actions of their competitors, unlike firms in a competitive market.

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 also incorrect, as it misrepresents the nature of an oligopoly. The defining characteristic of oligopolies is that the actions of any one seller can significantly affect the profits of others, which is the opposite of what this statement conveys.

Conclusion

The key features of an oligopoly include the limited number of sellers, the significant impact of one seller's actions on others, and the interdependence among firms. Options A, B, and D accurately capture these characteristics, while the other options fail to reflect the structural dynamics of oligopolistic markets. Understanding these features is crucial for analyzing market behavior and firm strategy within oligopoly frameworks.
