2. Monopoly
A Monopoly exists when a single firm dominates the market and has significant control over the price and supply of a product. Barriers to entry prevent other firms from entering the market.
Characteristics:
- Single seller.
- Unique product with no close substitutes.
- Price maker (sets its own price).
- High barriers to entry (legal restrictions, high start-up costs).
Real-Life Example:
Utility companies (e.g., electricity providers) often have a monopoly in certain areas because the infrastructure costs create high barriers to entry for competitors.
