Key Diagrams - Monopoly Supernormal Profit

This short revision video looks at the diagram used to show supernormal profit earned by a monopoly supplier.

A firm is said to reap monopoly profits when a lack of viable market competition allows it to set its prices above the competitive equilibrium price for a good or service without losing profits to competitors. Barriers to entry protect monopoly profit in the long run. Profit margins for a monopolist will tend to be higher when the coefficient of price elasticity of demand for their product is low.
