Key Concepts

Perfect Competition

Perfect competition is a market structure characterized by a large number of small firms selling homogeneous products, with free entry and exit from the market. In this environment, each firm is a price taker, meaning that no single participant has the power to influence market price. Monopolistic competition shares the feature of many competitors and free entry and exit, which tends to drive economic profits to zero in the long run, much like in perfect competition.

Monopoly

Monopoly is defined by a single seller who controls the entire market for a unique product with significant barriers to entry, allowing the firm to be a price maker with a downward sloping demand curve. In monopolistic competition, although there are many firms, each one differentiates its product in some way, granting it a degree of market power similar to a monopoly. This enables individual firms to set prices above marginal cost and earn short-run profits.

Monopolistic Competition

Monopolistic competition is a hybrid market structure that incorporates elements from both perfect competition and monopoly. It features many firms like perfect competition, ensuring that competition erodes long-run economic profits through free entry and exit. Simultaneously, product differentiation provides each firm with some control over pricing, akin to the market power exhibited in a monopoly. This results in a balance where firms can engage in non-price as well as price competition.
