In economic theory, imperfect competition is a type of market structure showing some but not all features of competitive markets.[1]

Forms of imperfect competition include:

  • Oligopoly, in which there are few sellers of a product.
  • Monopolistic competition, in which there are many sellers producing highly differentiated products.
  • Monopsony, where there are many sellers but only one buyer, and oligopsony, where there are many sellers but few buyers.
