oligopoly
An oligopoly is a market structure in which a few firms dominate. When a market is shared between a few firms, it is said to be highly concentrated. Although only a few firms dominate, it is possible that many small firms may also operate in the market.
Oligopolies may be identified using concentration ratios, which measure the proportion of total market share controlled by a given number of firms. When there is a high concentration ratio in an industry, economists tend to identify the industry as an oligopoly.
Types of Oligopoly:
Oligopoly is of two types:
(a) Pure Oligopoly:Here, the oligopolists sell practically homogeneous products. This type is found in steel, copper, cement petrol and a few other industries.
(b) Differential Oligopoly:
In such a case a few firms sell similar but not identical products under the same conditions. It is found in automobiles, tyres , electrical appliances, cigarettes, baby food and a few other industries.
