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.

Supply Curves Times Two

|
- Market control on the buying side of factor markets means that firms can face one of two types of supply curves for the factors their employ:
- Perfect Competition:
If we're looking for a buyer with absolutely no market control, then we are looking for perfect competition.
- Monopsony, Oligopsony, and Monopsonistic Competition:
If we're looking for a buyer with market control, then we can choose among monopsony, oligopsony, and monopsonistic competition.
- The relative elasticity of this curve depends, of course, on the market control of the buying firm.
