Question 45

Firms in an oligopoly are interdependent, there are a few sellers, and the actions of any one seller can significantly impact others.

In an oligopoly, the market structure is characterized by a small number of firms that are interdependent, meaning the decisions made by one firm can directly affect the others. Additionally, there are only a few sellers in the market, which amplifies the impact of each firm's actions on the overall market dynamics.

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

This statement accurately describes a key feature of oligopolies. Unlike competitive firms, which operate independently, firms in an oligopoly must consider the potential reactions of their competitors when making decisions about pricing, output, and other strategic choices.

B) Firms in an oligopoly are independent of one another, much like competitive firms.

This statement is incorrect as it contradicts the fundamental nature of oligopoly. In competitive markets, firms operate independently, but in an oligopoly, the interdependence of firms is a defining characteristic, meaning the actions of one firm can significantly influence the others.

C) There are a few sellers.

This statement is true and is one of the essential features of an oligopoly. The market is dominated by a small number of sellers, which leads to a limited competitive environment and allows each firm to have a notable influence on market prices and outputs.

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

This statement is misleading. While firms in an oligopoly may have competitive motivations, they often have significant incentives to cooperate, such as forming cartels or engaging in price-fixing to maximize profits collectively, which is a common practice in oligopolistic markets.

E) 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 and aligns with the nature of oligopoly. Each firm's decisions can lead to substantial changes in market conditions, affecting the profitability of all firms involved due to their interdependent relationships.

Conclusion

The correct features of an oligopoly include the interdependence of firms, the limited number of sellers, and the significant impact that one firm's actions can have on the others. Options A, C, and E highlight these characteristics effectively, while the other options misrepresent the dynamics of oligopoly, particularly regarding firm independence and motivation for cooperation.
