35 Examples of Monopoly and Oligopoly Companies (1)

Oligopoly is a market situation that occurs when the offerers or providers of a product or service are reduced to a small number of participants.

In this context, all the members of the sector are aware of the actions of their competitors. Oligopoly occurs when few companies share more than 70% of the market.

The entry of new companies is unlikely for economic or legal reasons. This situation can be due to the characteristics of the product or service or the composition of the market.

The monopoly, on the other hand, occurs when a company or economic agent has the exclusive privilege on the production and commercialization of a certain type of product or service.

This can occur because the goods are homogeneous, due to the existence of impediments to the entry of new bidders or through governmental intervention.

The oligopolistic situations can occur in different branches of the economy, whereas the monopolistic situations are less frequent. This is because in all countries an attempt is made to avoid dominant or abusive situations.

Between these two formats there is an intermediate option called the duopoly. It represents the cases in which all the goods or services of a productive segment are held by two competing companies.

In this article I will review some cases of companies that have exclusivity in the production of goods or services in the world. Many of them have regional competitors, which give legal validity to their practices.
