Key Concepts

Supernormal Profits

Supernormal profits, also known as economic profits, occur when a firm's total revenue exceeds its total costs, including both explicit and implicit costs. In the short run under monopolistic competition, firms may achieve these profit levels due to product differentiation and the temporary lack of competitive pressures from new entrants. However, such profits are often eroded in the long run as market entry continues until only normal profits remain.

Monopolistic Competition

Monopolistic competition is a market structure characterized by many firms producing differentiated products. In this structure, each firm holds some market power over its product due to differences in branding, features, or other attributes, allowing it to have some control over pricing. However, because there are many competitors and free entry and exit, the competitive pressures limit the extent of long-term pricing power.

Short-Run Equilibrium

Short-run equilibrium refers to the period during which certain market conditions, such as the number of firms or fixed costs, remain unchanged while firms adjust outputs based on demand and price. In the short run, firms can experience abnormal levels of profit or loss since adjustments such as entry or exit of firms have not yet occurred, and fixed factors restrict immediate responses to market signals.
