An oligopoly is a market structure in which there are few firms which are interdependent on each other such that price and output decisions of a firm affect other firms in the market. There is a high degree of competition in the market.
Firms in an oligopoly market can maximize profits by forming formal or informal collusion and reducing output level and increasing price.
