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.

Topic: Summary <=PAGE BACK | PAGE NEXT=>

  • How efficient use of resources can automatically result from the self-correcting tendency of markets to achieve equilibrium.
  • The demand price on the demand curve as the value of goods produced by society.
  • The supply price on the supply curve as the value of goods not produced by society.
  • How too much or too little production generates inequality between the demand price and the supply price, and prevents efficiency.
  • How market imperfections, including the lack of competition and externalities, prevent efficiency.

PRIVATE GOODS

Goods characterized by rival consumption and the ability to exclude nonpayers. Private goods are one of four types of goods differentiated by consumption rivalry and nonpayer excludability. The other three goods are public (nonrival consumption and nonpayers cannot be excluded), common-property (rival consumption and nonpayers cannot be excluded), and near-public (nonrival consumption and nonpayers can be excluded). Rival consumption and the ease of excluding of nonpayers means private goods can be efficiently exchanged through markets.
