What is an Oligopoly?
An oligopoly is a market structure in which a few large firms dominate the market. In this market structure, the actions of one firm can have a significant impact on the other firms in the market. The firms in an oligopoly often have significant barriers to entry, which makes it difficult for new firms to enter the market.

Characteristics of an Oligopoly
In addition to dominating the market and having significant barriers to entry, there are several other characteristics of an oligopoly. Some of these characteristics include:
1. Interdependence
In an oligopoly, the actions of one firm can have a significant impact on the other firms in the market. This means that firms in an oligopoly are interdependent and must consider the actions of their competitors when making decisions.
2. Collusion
Collusion is an agreement between two or more firms to limit competition in the market. In an oligopoly, collusion is often used to maintain high prices and keep out new competitors.
3. Price Leadership
In an oligopoly, one firm often takes the lead in setting prices for the market. The other firms then follow this lead and set their prices accordingly.
4. Non-Price Competition
In an oligopoly, firms often engage in non-price competition, such as advertising and product differentiation, to gain a competitive advantage.
The Impact of Oligopolies
Oligopolies can have a significant impact on the economy and consumers. Some of the impacts of oligopolies include:
1. Higher Prices
Oligopolies often maintain high prices in the market, which can lead to higher costs for consumers.
2. Limited Innovation
Oligopolies may have less incentive to innovate and develop new products because they have a dominant position in the market.
3. Limited Consumer Choice
Oligopolies may limit consumer choice by controlling a significant portion of the market and limiting the number of competitors.
4. Increased Collusion
Oligopolies may collude to maintain their dominant position in the market, which can limit competition and innovation.
Conclusion
In conclusion, oligopolies are a significant market structure that can have a significant impact on the economy and consumers. Understanding the characteristics and impacts of oligopolies is important for policymakers and consumers alike.
