Key Concepts

Interdependence

Interdependence in an oligopoly means that the decisions of one firm, such as adjusting prices or launching new products, have substantial impacts on the decisions of rival companies. This mutual reliance can lead to strategic planning and sometimes even coordinated behavior, as firms must consider their competitors' potential reactions when making their own business decisions.

Barriers to Entry

Barriers to entry are obstacles that make it difficult for new competitors to enter a market. In oligopolistic markets, these barriers often include high startup costs, established brand loyalty, and regulatory hurdles, all of which contribute to maintaining the dominance of the existing few firms by preventing new competitors from easily entering the market.

Market Concentration

Market concentration refers to the degree to which a small number of firms dominate total sales or production in a market. High concentration is a hallmark of oligopolistic industries and indicates that the market is controlled by a few powerful players, which can limit competition and influence market outcomes significantly.

Oligopoly

An oligopoly is a market structure in which a small number of firms hold the majority of market share. This concentration of firms often leads to interdependent decision-making where each firm's actions, such as pricing or output decisions, directly affect the competitors, leading to strategic behaviors and sometimes even tacit or explicit collusion.
