In pursing its own interest, an oligopoly firm will decide to increase production by 1 unit as long as the output effect is larger than the price effect. An oligopoly happens when there is limited competition because there are only a small number of producers or sellers in the market. Due to limited competition there is no need for most of these businesses to produce more unless the output is going to produce more and become sustainable for their consumers demand.
