PERFECT COMPETITION AND EFFICIENCY: Perfect competition is the idealized market structure that achieves an efficient allocation of resources. The conditions of perfect competition, including (1) large number of small firms, (2) identical products sold by all firms, (3) freedom of entry into and exit out of the industry, and (4) perfect knowledge of prices and technology, ensure that perfect competition efficiently allocates resources.

Two reasons: - First: Money improves efficiency by reducing the amount of resources that would be needed for barter exchanges.
- Second: Money improves efficiency by letting resources specialize in production.
