Explanation:

An oligopoly occurs when a small number of firms operate in a market, and firms cannot control the influence of other firms in the market. Each firm has the ability to influence the market.

A key feature of oligopoly is interdependence. Firms look at other firms behaviours before making decisions. It is a form of tacit collusion.

Decisions on output, price, advertising and other depends on decision of other firms in the market.
