Everyday Examples of Oligopoly and Monopolistic Competition

📚 Quick Study Guide

• 🏢 Oligopoly: A market structure dominated by a few large firms. Key characteristics include high barriers to entry, interdependence among firms, and potential for collusion. Examples: airline industry, telecommunications.
• 🚗 Monopolistic Competition: A market structure with many firms selling differentiated products. Key characteristics include low barriers to entry, product differentiation, and advertising. Examples: restaurants, clothing stores.
• 🧱 Barriers to Entry: Obstacles that prevent new firms from entering a market. These can be legal (patents), economic (high start-up costs), or strategic (aggressive pricing by existing firms).
• 🤝 Interdependence: Firms in an oligopoly must consider the actions of their competitors when making decisions about pricing and output.
• 📊 Market Concentration: A measure of the degree to which a small number of firms control a large share of the market. High concentration ratios indicate an oligopoly.
• 📢 Product Differentiation: The process of distinguishing a product or service from its competitors. This can be based on quality, features, branding, or location.
• 💡 Advertising: A key tool used by firms in monopolistic competition to promote their products and differentiate them from the competition.
