Definition
An oligopoly is a market structure where a small number of firms have a large market share and dominate the production and sales of particular goods or services. These firms are interdependent, meaning the actions of one firm can significantly impact the others.
This structure is more concentrated than perfect competition but less concentrated than a monopoly. The result is less market freedom compared to perfect competition, leading to higher prices and reduced consumer choices.
Key Characteristics of Oligopoly
- Few Large Firms: The market is dominated by a small number of large firms.
- Mutual Interdependence: Each firm’s decisions regarding production, pricing, marketing, etc., directly affect the other firms in the market.
- Barriers to Entry: High entry barriers such as significant capital investments and technology requirements prevent new competitors from entering the market.
- Non-Price Competition: Firms often compete based on factors other than price, such as advertising, product differentiation, and customer service.
Examples of Oligopoly Markets
- Automobile Industry: Dominated by a few major players like General Motors, Ford, and Toyota.
- Airline Industry: Airlines like American Airlines, Delta Air Lines, and United Airlines control a large portion of the market.
- Telecommunications: Companies like AT&T, Verizon, and T-Mobile dominate the market.
