Perfect Competition
Perfect Competition is a market structure where many firms sell identical products, and no single firm has market power to set prices. Firms are price takers, meaning they must accept the market price determined by supply and demand. Entry and exit into the market are relatively easy, leading to minimal barriers to competition.
Example: A market for agricultural products like wheat. Many farmers produce wheat, and no single farmer can influence the market price. The price of wheat is determined by the aggregate supply and demand in the market.
Monopoly
Monopoly is a market structure where a single firm is the sole producer of a product or service with no close substitutes. The monopolist has significant market power and can set prices above marginal cost. Barriers to entry are high, often due to legal restrictions, economies of scale, or exclusive control over essential resources.
Example: A local utility company that provides electricity to a city. The company has exclusive rights to distribute electricity, allowing it to set prices and control the market.
Oligopoly
Oligopoly is a market structure where a small number of firms dominate the market. These firms have significant market power and can influence prices, but they must consider the actions of their competitors. Oligopolies often result in strategic behavior, such as price wars, collusion, or product differentiation.
Example: The market for smartphones, where a few large companies like Apple, Samsung, and Huawei dominate. These firms compete intensely, often differentiating their products to capture market share.
Monopolistic Competition
Monopolistic Competition is a market structure where many firms sell similar but differentiated products. Each firm has some market power to set prices due to product differentiation, but entry and exit are relatively easy. Firms compete on product features, quality, and marketing rather than price alone.
Example: The market for restaurants in a city. Each restaurant offers a unique dining experience, but there are many restaurants to choose from. Firms compete on cuisine, ambiance, and service to attract customers.
