Supply, Demand & Market Structures
Supply refers to the quantity of a product or service that producers are willing to offer at various prices, while demand is the amount consumers are ready to purchase at those prices. Market structures describe the organization and characteristics of markets, including factors like the number of sellers, product differentiation, and entry barriers. Common market structures include perfect competition, monopoly, monopolistic competition, and oligopoly, each influencing how supply and demand interact to determine prices and outputs.

💡 Key Takeaways
- Define supply and demand and explain how price changes influence producers and consumers.
- Explain what causes shifts in supply and demand curves, not just movements along them.
- Identify major market structures (perfect competition, monopoly, oligopoly, monopolistic competition) and their defining characteristics.
- Assess how market structure and the number of sellers affect prices, output, and efficiency in a market.
❓ Frequently Asked Questions
What is supply?
Supply is the quantity of a product or service that producers are willing to offer at different prices; it generally rises when prices rise (the law of supply).
What is demand?
Demand is the quantity of a product or service that consumers are willing to buy at different prices; it generally falls when prices rise (the law of demand).
What are market structures?
Market structures describe how markets are organized, including the number of sellers and how similar or differentiated the products are (e.g., perfect competition, monopoly, monopolistic competition, oligopoly).
What happens when prices are above or below the equilibrium price?
Prices above the equilibrium create a surplus (more supply than demand); prices below create a shortage (more demand than supply). The market tends toward equilibrium.
