What Majors Use Game Theory?

Game theory is a branch of mathematics that has found applications in various fields. It is the study of decision-making in situations where two or more individuals or groups have conflicting interests.

Game theory helps us to understand how people behave and interact in strategic situations. In this article, we will explore the majors that use game theory.


Game theory is widely used in economics to study the behavior of individuals and firms in markets. It helps economists to understand how different market structures impact prices, profits, and consumer welfare.

Game theory is also used to analyze strategic interactions between firms, such as price competition, product differentiation, and advertising. Some of the popular game-theoretic models used in economics include the prisoner’s dilemma, the Nash equilibrium, and the Bertrand model.

Political Science

Political scientists use game theory to study international relations, conflict resolution, and voting behavior. Game theory helps political scientists to understand how countries interact with each other in strategic situations such as war and negotiation. It also helps them to analyze voting behavior by modeling elections as games between political parties.

Computer Science

Game theory has numerous applications in computer science and artificial intelligence. It is used to develop algorithms for decision-making in multi-agent systems such as autonomous vehicles, robots, and drones. Game theory also plays a crucial role in designing online auctions and electronic markets.


Game theory has become an essential tool for biologists studying evolution and animal behavior. It helps biologists to understand how animals make decisions about their actions based on their environment and other animals’ behavior. Biologists use game-theoretic models to explain phenomena such as cooperation among animals, predator-prey relationships, and mating strategies.


Psychologists use game theory to study social dilemmas such as trust, cooperation, and conflict resolution. Game theory helps them to understand how people make decisions when faced with uncertain outcomes and how their behavior is influenced by the actions of others. It is also used to study social norms, group dynamics, and bargaining behavior.


In conclusion, game theory is a versatile field that has found applications in various majors. From economics to psychology, game theory has helped us to better understand human behavior and decision-making in strategic situations. As the world becomes more complex, game theory will continue to play a crucial role in shaping our understanding of strategic interactions between individuals and groups.
