Defining Duopoly

A duopoly refers to a market structure dominated by two interdependent companies.

Several industries, such as the soft drink market with Coca-Cola and Pepsi, exemplify the defining duopoly dynamics.

What Are the Characteristics of a Duopoly?

Duopoly refers to a market structure where there are only two dominant companies that control a significant portion of the market share. In this section, we will explore the characteristics of a duopoly and how they differ from other market structures. We will discuss the presence of two dominant companies, limited competition, interdependence between the companies, and the barriers to entry that make it difficult for new companies to enter the market. By understanding these key characteristics, we can gain a better understanding of how duopolies function within the larger economy.

1. Two Dominant Companies

  • Discover the industries dominated by two key players.
  • Analyze their market share and influence on pricing.
