Summary
Perfect competition, monopoly and imperfect competition are three market structures. Students learn how they differ in features such as price, demand, and information.
Market Structures
Perfect competition, monopoly, monopolistic competition and oligopoly are the four market structures. They differ in features such as price, demand, and information.
Features of Market Structures
A table compares the four market structures. It shows how they differ in economic efficiency, price, demand, collusion, innovation, and information.
Price and Cost
Price and cost vary across the four market structures. For example, in perfect competition, price equals marginal cost. In monopoly, price is greater than marginal cost.
Profit Maximisation
Firms in each market structure try to maximise profit. They do this by adjusting price and output. For example, in monopoly, a firm can make abnormal profits.
