Term perfect competition and efficiency Definition: 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. This is in fact the purpose of perfect competition: a market structure that illustrates perfection, the best of all possible resource allocation worlds. The real world falls short of this perfection.
