Perfect and imperfect oligopolies are often distinguished by the nature of the goods firms produce or trade in.

These markets are also defined by the presence of monopolies, oligopolies and externalities within the market.

Oligopolies are usually found in industries in which initial capital requirements are high and existing companies have strong foothold in market share. Monopoly: The number of enterprises is only one, access is restricted or completely blocked, and the products produced and sold are unique and cannot be replaced by other products.
