Welcome to our CFA Level 1 lesson on oligopoly. An oligopoly is a market structure characterized by a small number of large firms that dominate the market. Unlike perfect competition with many small firms, or monopoly with just one firm, oligopoly features few major players. The key defining characteristic is interdependence - each firm's pricing and output decisions significantly impact their competitors' profits and market share.
In oligopoly, supply and demand dynamics are more complex than in other market structures. Unlike perfect competition where firms are price takers, or monopoly where one firm controls the entire market, oligopolistic firms face uncertain demand curves. A firm's individual demand depends heavily on how competitors react to its pricing decisions. This creates strategic uncertainty - firms must constantly anticipate and respond to rivals' moves.
Oligopolistic firms employ various pricing strategies due to their interdependence. Collusion involves firms cooperating to maximize joint profits, essentially acting like a monopolist, though this is often illegal. Price leadership occurs when one dominant firm sets prices and others follow. Nash equilibrium represents a stable outcome where each firm chooses its best strategy given competitors' choices. Finally, price wars involve aggressive price cutting that can harm all firms' profitability.
Let's examine a simple game theory example with two gas stations. Each station can choose either high or low pricing. The payoff matrix shows daily profits in dollars. If both choose high prices, they each earn 100 dollars. However, if one cuts prices while the other maintains high prices, the price-cutter earns 150 while the other earns only 50. The Nash equilibrium occurs at low-low pricing, where both earn 80 dollars, because neither firm has an incentive to unilaterally change their strategy.
Let's summarize the key takeaways about oligopoly for your CFA Level 1 exam. Remember that oligopoly is defined by few large firms dominating a market, with interdependence being the crucial characteristic. Firms face uncertain demand curves due to strategic interactions with competitors. The main pricing strategies include collusion, price leadership, Nash equilibrium outcomes, and price wars. Game theory provides a framework for analyzing these strategic decisions. For the CFA exam, focus on understanding the concept of interdependence and how it drives strategic behavior in oligopolistic markets.
