Monopoly
In economics, a monopoly is defined as a market structure where a single seller controls the entire supply of a product or service with no close substitutes. This unique position results in significant pricing power, allowing the monopolist to set prices above equilibrium levels seen in competitive markets.
Key Characteristics of Monopoly:
- Single Seller: There is only one firm providing the goods or services in the market.
- No Close Substitutes: The product or service has no close alternatives, making consumers dependent on the monopolist.
- High Entry Barriers: Barriers such as capital requirements, regulatory hurdles, and economies of scale prevent other firms from entering the market.
- Price Maker: The monopolist can influence prices, unlike price-takers in perfectly competitive markets.
Importance in Economics:
Understanding monopolies is crucial as they can lead to market inefficiencies and consumer harm, such as higher prices and reduced output. Common examples include monopolistic practices in utilities like railways and electricity provision in certain regions.
