Meaning of Duopoly:

Duopoly is that market situation where there are only two firms operating in the market. Since there are only two firms producing identical goods under duopoly any change in price or output by one firm is bound to affect the other. In duopoly the individual firm has to carefully consider the indirect effect of its own decision to change its price or output or both. There are three classical duopoly models given by Court not, Edge worth and Chamberlin. The features of monopoly are very simple.

Many economist are of the opinion that duopoly is only a firm of simple oligopoly. In other words duopoly is only limited oligopoly. Duopoly models and explanation can also be taken as oligopoly models. Duopoly is a market with two sellers exercising control over the supply of commodities it is a two firms industry.

In the words of Cohen and Crete “where there are exactly two sellers in the market, there is a special case of oligopoly called duopoly.” Each seller knows whatever he does will affect his rival policies. Each seller attempts to make a correct guess of his rival motives and actions the action by one will have a reaction from the other.

FEATURES OF DUOPOLY MARKET

A duopoly is a market structure in which there are only two significant competitors or firms that dominate the entire industry. Duopolies are characterized by a strategic interdependence between the two firms, as each firm’s decisions and actions have a direct impact on the other. Here are some features of a duopoly market in economics:

1. Two Dominant Firms: A duopoly consists of two main players or firms that dominate the market. These firms have a substantial market share and influence over the industry.
2. Strategic Interdependence: The actions and decisions of one firm directly affect the other. Firms in a duopoly must consider the potential reactions of their competitor when making strategic choices, such as pricing, production levels, and marketing.
3. Limited Competition: Due to the small number of firms, competition is limited compared to more competitive market structures like perfect competition. The behavior of each firm has a significant impact on market outcomes.
4. Product Differentiation: While products may be similar, there is often some degree of product differentiation to distinguish one firm’s offerings from the other. This differentiation can be in terms of quality, features, or branding.
5. Barriers to Entry: Entry barriers exist, making it difficult for new firms to enter the market and compete with the established duopoly. These barriers may include high startup costs, access to distribution channels, and economies of scale.
6. Price Rigidity: Duopoly sellers may engage in price rigidity, where they avoid frequent price changes due to the potential for retaliation by the other firm. This can lead to price stability in the market.
7. Collusive Behavior: Firms in a duopoly may engage in collusion, where they coordinate their actions to maximize joint profits. Collusion can take the form of price-fixing, output restrictions, or other cooperative agreements.
8. Non-Price Competition: Competition may extend beyond prices, with firms focusing on non-price factors such as product quality, advertising, and customer service to gain a competitive edge.
9. Oligopolistic Tendencies: Duopolies share some characteristics with oligopolies, which are markets dominated by a small number of large firms. However, the distinction lies in the specific number of firms involved.
10. Game Theory Application: Game theory is often applied in the analysis of duopolies to understand the strategic interactions between the two firms and predict their likely behavior.
