Oligopolies represent a market structure characterized by a small number of firms dominating the industry, leading to a complex interplay of competitive and cooperative behaviors. There are three primary types of oligopolies: open, tacit, and pure oligopolies, each distinguished by the degree of collusion and market interdependence among firms. Understanding these distinctions is essential to grasping how firms in such markets behave and influence prices.

Open oligopolies are those where firms explicitly recognize each other's presence and actively engage in collusion through formal agreements. These agreements often take the form of cartels, where participating firms agree to set prices or output levels to maximize combined profits, effectively functioning as a monopoly. The most notorious example of an open oligopoly is OPEC (Organization of Petroleum Exporting Countries), where member countries coordinate oil production quotas to influence global prices explicitly. The legality of such collusions varies by jurisdiction, with many countries banning explicit collusion under antitrust laws.

Tacit oligopolies, on the other hand, involve firms that avoid formal agreements but recognize their mutual interdependence and adjust their prices based on the expected reactions of rivals. This form of implicit collusion is maintained through strategic signaling and observation rather than explicit contracts. For instance, in the airline industry, airlines may implicitly coordinate their pricing strategies by observing competitors’ fares and adjusting accordingly to avoid a price war, thus maintaining higher profit margins. Tacit collusion relies heavily on market transparency and the ability of firms to monitor each other's behavior without explicit communication, making enforcement of such collusion inherently fragile.

Pure oligopolies refer to markets where firms do not collude either explicitly or implicitly but still influence each other's pricing decisions. In this scenario, each firm considers the potential reactions of rivals when setting prices, often leading to strategic decision-making akin to game theory models like the prisoners' dilemma. An example can be seen in the automobile industry, where firms independently set prices but are aware that their actions influence competitors’ strategies. The lack of collusion often results in prices that are somewhat stable but still highly sensitive to changes in costs, demand, and competitive moves.

In collusive scenarios, such as with cartels, prices are set collectively by the producers to maximize joint profits. Cartel members agree on the quantity to produce and the prices to charge, effectively acting as a monopoly. This cooperation leads to higher prices and restricted output, benefitting cartel members at the expense of consumers. However, maintaining such collusion poses challenges due to the temptation for individual firms to cheat on agreements to increase their own share of profits, leading to unstable cartel arrangements.

Oligopolies that engage in implicit collusion set their prices by observing and reacting to competitors’ actions without formal agreements. Firms keep track of rivals’ pricing strategies and adjust their own accordingly, often leading to a stable pricing environment. This tacit understanding is reinforced by the fear of price wars and the desire to maintain higher profits. An illustrative example is in the banking sector, where banking institutions typically avoid aggressive price cutting, instead following dominant players’ pricing moves to maintain market stability, even without explicit communication.

Non-colluding oligopolies, which do not cooperate or tacitly coordinate, determine their prices based on independent strategies considering market conditions, costs, and estimated reactions of competitors. These firms often compete fiercely through pricing, advertising, and product differentiation. Their pricing decisions are primarily driven by the desire to maximize individual profits rather than joint gains. Game theory models such as the Cournot and Bertrand models describe these competitive behaviors, where firms choose quantities or prices to optimize outcomes in competitive yet interdependent environments. Prices tend to be stable over time but can fluctuate significantly due to changes in demand, costs, or entry of new competitors.

In conclusion, the various types of oligopolies exhibit differing degrees of cooperation and competition, profoundly affecting how they set prices. Cartels explicitly collude to fix prices, while tacit collusion relies on strategic signals and market monitoring. Non-colluding firms act independently, often leading to intense competition and variable pricing. Recognizing these distinctions helps in understanding the dynamics within oligopolistic markets and the implications for consumers, producers, and regulators.
