Game Theory in Oligopoly: Strategy, Payoffs & Decision-Making
This paper introduces game theory as a mathematical framework for analyzing strategic decision-making among competing firms, with a focus on oligopoly markets. Using a two-airline scenario, it explains core concepts such as players, payoffs, and the payoff matrix. The paper illustrates how firms must account not only for their own strategies but also for anticipated competitor responses. Through a worked numerical example involving loyalty scheme investment, it demonstrates how mutual cooperation yields better long-term outcomes than mutual defection, while also exploring the temptation to cheat on agreements and the cascading consequences that follow.

What makes this paper effective
- The paper grounds an abstract economic concept in a concrete, relatable industry example (airline loyalty schemes), making the theory accessible without sacrificing analytical depth.
- It uses a clearly labeled payoff matrix to translate verbal reasoning into a visual, quantitative format, reinforcing the mathematical nature of game theory.
- The paper follows a logical progression from definition to application to implication, giving readers a complete conceptual arc.
Key academic technique demonstrated
The paper demonstrates applied economic modeling — taking a formal theoretical framework (game theory) and operationalizing it through a step-by-step scenario. By assigning specific dollar values to each outcome in the matrix, the author shows how abstract strategic reasoning can be tested and visualized quantitatively, a technique central to managerial economics and industrial organization.
Structure breakdown
The paper opens with a definition of game theory and its applicability to oligopoly markets, then introduces the components of a game (players, decisions, payoffs). It constructs a two-firm airline scenario, walks through the logic of cooperation versus defection across multiple rounds, and presents a 2×2 payoff matrix. The conclusion generalizes the model's relevance to real-world multi-player competitive environments.
Introduction to Game Theory
Game theory is a model used to examine and explain the way different actors in a given situation may choose to act and develop strategy, using a mathematical approach. The model looks at how players will make decisions based on both their own position and resources as well as the way their competitors are acting or are expected to act. Game theory can therefore be used to help identify the optimal course of action (McEachern, 2009).
Game Theory in Oligopoly Markets
There are many scenarios where game theory is useful. In the commercial environment, game theory is most applicable in oligopoly situations — though its use is not limited to these contexts.
To consider the application of the theory, the core concept must first be described. The situation being examined is called a game. For there to be a game, players are required; in a business context, these players are firms (Nellis and Parker, 2006). For a game to commence, there must be at least two players making decisions that will impact on each other. Each set of decisions made by the players produces an outcome referred to as the payoff (McEachern, 2009). An effective way of examining game theory is to work through an example and observe how decisions affect the different players. A useful example is the airline industry, where only a limited number of carriers travel each route.
