The two main types of economic markets are perfect competition and monopoly. In a perfect competition market, numerous buyers and sellers exist, leading to an optimal distribution of resources and prices determined by supply and demand. In contrast, a monopoly is characterized by a single seller dominating the market, allowing them to set prices without competition, often leading to inefficiencies and reduced consumer choice. Other market structures, such as monopolistic competition and oligopoly, also exist but are variations of these two primary types.
A true duopoly is a specific type of oligopoly where only two producers exist in one market. In reality, this definition is generally used where only two firms have dominant control over a market. In the field of industrial organization, it is the most commonly studied form of oligopoly due to its simplicity.
