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. 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.

INCREASING RETURNS TO SCALE

A given proportional change in all resources in the long run results in a proportional greater change in production. Increasing returns to scale exists if a firm increases ALL resources--labor, capital, and other inputs--by a given proportion (say 10 percent) and output increases by more than this proportion (that is more than 10 percent). This is one of three returns to scale. The other two are decreasing returns to scale and constant returns to scale.
