An oligopoly is a market dominated by a few large suppliers. The degree of market concentration is very high (i.e. a large % of the market is taken up by the leading firms). Firms within an oligopoly produce branded products (advertising and marketing is an important feature of competition within such markets) and there are also barriers to entry.
Another important characteristic of an oligopoly is interdependence between firms. This means that each firm must take into account the likely reactions of other firms in the market when making pricing and investment decisions. This creates uncertainty in such markets - which economists seek to model through the use of game theory.
Economics is much like a game in which the players anticipate one another's moves.
Game theory may be applied in situations in which decision makers must take into account the reasoning of other decision makers. It has been used, for example, to determine the formation of political coalitions or business conglomerates, the optimum price at which to sell products or services, the best site for a manufacturing plant, and even the behaviour of certain species in the struggle for survival.

The ongoing interdependence between businesses can lead to implicit and explicit collusion between the major firms in the market. Collusion occurs when businesses agree to act as if they were in a monopoly position.
