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.

The real world falls short of this perfection.

This is one of two taxation principles. The other is the benefit principle, which states taxes should be based on the benefits received.
