Oligopolimarkkinat describe a market structure characterized by a small number of large firms that dominate the industry. These firms are interdependent, meaning the actions of one firm significantly impact the others, and vice versa. This interdependence can lead to complex strategic behavior, such as price wars, collusion, or non-price competition.

Key features of an oligopoly include high barriers to entry, which make it difficult for new firms to join the market. These barriers can be due to economies of scale, brand loyalty, patents, or control over essential resources. Products in an oligopolistic market can be either differentiated or homogeneous. Examples of industries that often exhibit oligopolistic characteristics include the automotive industry, telecommunications, and the airline industry.

The behavior of firms in an oligopoly is a central topic in microeconomics. Game theory is often used to analyze the strategic interactions between these firms. Firms may engage in price leadership, where one firm sets the price and others follow, or they might engage in tacit collusion, where they implicitly coordinate their actions without explicit agreements to maintain higher prices. However, explicit collusion to fix prices is illegal in most jurisdictions due to antitrust regulations. The outcome for consumers in an oligopolistic market can vary; while competition might be limited, the firms may still compete through innovation and product differentiation to gain market share.
