A duopoly is a market situation that entails two competing companies that share the market. In this market, two brands can collude to set prices or quantity and make customers pay more money.

As any market structure duopoly has a significant impact on how companies interact with each other. Since there are only two players within the market, the actions of one will affect the response and activity of the other, but not only. They also influence the way a company operates, how it produces and promotes its products.

In this article, we’ll uncover the features of a duopoly, its advantages and disadvantages, and make the difference between a duopoly and an oligopoly clear. Then, we’ll review the types and examples of a duopoly.

Features of a Duopoly

Duopoly is a market structure similar to oligopoly. Yet, it still has some distinctive features. The first thing that distinguishes this market structure is that there are only two companies that share a market. Secondly, the businesses that exist within a duopoly are interdependent. To win the attention of customers, companies often take strategic actions such as price reductions. If one company makes its product cheaper, the other will follow. This is necessary to attract consumers and encourage them to purchase.

It’s worth mentioning that players can collude to determine a price or output or maintain a competitive environment for great profits. Since companies in a duopoly take different measures to develop brand loyalty and implement low-pricing strategies, it’s hard for new firms to enter. As a result, sales volume and revenues are good enough. This is because there is only one competitor and the barriers to entry are high.

Knowing the features of this market situation allows you to proceed to the next section where we’ll discuss the pros and cons of a duopoly.

Advantages and Disadvantages of a Duopoly

Duopoly is a market situation that influences businesses and consumers both positively and negatively.

Its advantages include the absence of other competitors. It gives all the opportunities for two companies to collaborate to receive the highest profits. To put it simply, this market situation makes collusive cooperation possible.

Firms in a duopoly don’t strive to bring new products or services to the market. They rather concentrate on bringing innovation to the existing products and services. Considering the fact that the market is divided only between two businesses, It’s worth pointing out that they are the ones to control prices and also prevent other businesses from entering the market.

The main disadvantage of a duopoly is that it creates limits for free trade. The existence of only two companies within the market significantly limits the choice of products for customers. For new firms, it’s difficult to join the market and obtain some market share because of the barriers existing companies create. One more drawback of a duopoly is that it has price fixing and collusion. As a result, consumers have only a few alternatives but still have to pay a high price.

Duopoly vs Oligopoly

Both duopoly and oligopoly create high barriers to entry, making it impossible for new companies to enter. They are also similar in authority and power their players have since the competition is low. Also, businesses within these market structures choose cooperation rather than competition to maximize their profits. After all, the number of companies is limited, so customers have only a few alternatives.

However, duopoly and oligopoly differ in the number of companies a market has. While in an oligopoly we can see a small number of companies (two and more), in a duopoly the number of players is limited to two and the market is divided in half. Under a duopoly, firms have monopoly power and interdependence in strategies. The decision of one business will definitely influence the other company.

Now it’s time to move to the types of duopoly.

Types of Duopoly

Duopolies can be divided into two main groups:

  • Cournot duopoly. According to this duopoly, the output of produced goods and services shapes the competition between players. Businesses in this market system manufacture a certain amount of products to maximize their profits. Besides, companies negotiate to divide the market. This type also excludes the presence of collusion. In the long run, companies establish stable prices and output.
  • Bertrand duopoly. In this market situation, the price shapes competition between companies. Customers opting for the firms with the lowest price can cause price war and high competition between players. As a consequence, brands implement low-pricing strategies and lose profit while consumers enjoy purchasing products or services for incredibly low prices.

To put it simply, the two types differ in triggers that cause competition between players within the market situation. So, now let’s proceed to the examples of duopolies.
