Types of Duopoly

The two principal kinds of duopoly: the duopoly of Cournot and Bertrand.

According to the Cournot duopoly model, the competition between two businesses in an industry is shaped by the quantity of goods or services produced. The model assumes that the two businesses collaborate to divide the market among themselves. In order to maintain the equilibrium of a half and half split of the market, one company must alter its production levels if the other company does the same.

While, according to the Bertrand duopoly model, the competition between the two businesses is shaped by price, not production quantity. When two options of equal quality are given, the model predicts that consumers will select the product with a lower price. This suggests that the duopoly’s two businesses will compete on price to gain market dominance.

Implications of Duopoly

Each business in a duopoly market is decisively reliant upon the other. It has an effect on the way individual businesses operate, produce goods, advertise products, and set prices. The strategies employed by each organization determine the competition’s outcomes.

 When two businesses compete on price, it can result in higher prices, especially when the products are comparable. The products of each company completely substitute for one another because of the uniformity. Consequently, a lower price is the customer’s top priority when making a purchase. They have no intention to incline toward or be faithful to a specific item over the other.

  • Customers switch when one company lowers its prices, reducing a competitor’s market share. To avoid losing market share, rivals will also reduce their prices. There are price wars that start and continue until prices reach the marginal cost, which reduces profit potential.
  • Competition based on quantity Duopolies perform better when the basis of competition is volume rather than price. Profits and the market are divided among each company. As in the Cournot model, when it arrives at the ideal, creation and costs settle.
  • Each business will also reap substantial profits. While still operating in a monopolistic market, both businesses can charge prices that are higher than the marginal cost and above the perfectly competitive price. To put it another way, they each hold a monopoly.
  • In a duopoly market, execution is one more level of contention. Each business differentiates its offerings to encourage customer loyalty. In the market, differentiation leads to a monopolistic situation. The company’s monopolistic power will grow as a result of the devotion of its customers to each product.

Due to a small number of businesses becoming more and more efficient, the trend toward duopolistic behavior in businesses is growing. These businesses have greater access to capital that can assist them in acquiring or putting their rivals out of business.

However, in a developing nation like India, where people have fewer options for purchasing goods and services, healthy competition between businesses will be beneficial for the long run.
