In economic theory, imperfect competition is the competitive situation in any market where the conditions necessary for perfect competition are not satisfied. It is a market structure that does not meet the conditions of perfect competition. [1]
Forms of imperfect competition include:
- Monopoly, in which there is only one seller of a good.
- Oligopoly, in which there is a small number of sellers.
- Monopolistic competition, in which there are many sellers producing highly differentiated goods.
- Monopsony, in which there is only one buyer of a good.
- Oligopsony, in which there is a small number of buyers.
- Information asymmetry when one competitor has the advantage of more or better information.
There may also be imperfect competition due to a time lag in a market. An example is the “jobless recovery”. There are many growth opportunities available after a recession, but it takes time for employers to react, leading to high unemployment. High unemployment decreases wages, which makes hiring more attractive, but it takes time for new jobs to be created.
