The modern world is driven by decisions. Decisions are made to exert substantial control and impact in all fields of endeavor, in all industries, and in all circumstances. Many strategies and tools are used by people to improve their decision making. Game theory is one of these tools.

Game theory is a powerful instrument that helps understand how people or groups interact strategically in various circumstances such as politics, economics, biology to psychology. Throughout this article, I will give an in-depth overview of game theory and explain how it applies to both business and conflict in our current society.

After reading this article, you will have a better understanding of game theory and its applications. Ready? Let us get started right away!

What is Game Theory?

Game theory is a theoretical framework for conceiving social situations among competing players. In some respects, game theory is the science of strategy, or at least the optimal decision-making of independent and competing actors in a strategic setting.

Game theory defines a game as any set of circumstances that has a result dependent on the actions of two or more decision-makers. This interdependence causes each player to consider the other player’s decisions, or strategies, in formulating strategy.

Game theory has two main branches: non-cooperative game theory and cooperative game theory. Non-cooperative game theory studies games where players act independently and do not form coalitions or make binding agreements. Cooperative game theory studies games where players can form coalitions and make binding agreements.

Game Theory in Business

Game theory has many applications in business, where strategic interactions among firms can determine market outcomes and profits. One example is the prisoner’s dilemma game, where two firms must decide whether to collude or compete in a market. If both firms collude, they can earn higher profits than if they compete. However, if one firm defect and the other colludes, the defector can earn even higher profits. If both firms defect, they both earn lower profits than if they had colluded. The prisoner’s dilemma game shows that even if it is in the best interest of both firms to collude, they may end up competing due to the fear of being taken advantage of by the other firm.

Another example is the Bertrand competition game, where two firms compete by setting prices for a homogeneous product. If the firms have identical costs, they will set the price equal to the marginal cost and earn zero profits. However, if one firm lowers its price slightly below the other firm’s price, it can capture the entire market and earn positive profits. The Bertrand competition game shows that even in a perfectly competitive market, firms can earn positive profits by strategically setting prices.

Game Theory in War

Game theory also has applications in war and conflict, where strategic interactions among countries or groups can determine the outcomes of battles and wars. One example is the prisoner’s dilemma game applied to nuclear deterrence. If two countries have nuclear weapons, they must decide whether to disarm or deter each other. If both countries disarm, they can avoid the catastrophic consequences of a nuclear war. However, if one country disarms and the other does not, the disarmed country is vulnerable to attack. If both countries deter each other by maintaining their nuclear weapons, they both face the risk of accidental or intentional nuclear war. The prisoner’s dilemma game shows that even if it is in the best interest of both countries to disarm, they may end up maintaining their nuclear weapons due to the fear of being attacked by the other country.

Another illustration is the game of chicken, in which two nations threaten to escalate a conflict until the other side gives in. If neither nation yields, they will collide and suffer heavy losses. But if one side capitulates, it will lose credibility and run the risk of being used as a bargaining chip by the other side in future battles. The game of chicken shows how, even when both nations wish to avoid war, they may end up acting recklessly and dangerously out of concern for their reputation and image.

Game Theory and Negotiation

Game theory also has applications in negotiation, where strategic interactions among parties can determine the outcomes of agreements and contracts. One example is the ultimatum game, where one player proposes a division of a fixed amount of money and the other player can accept or reject the proposal. If the proposal is rejected, both players receive nothing. The ultimatum game shows that fairness and equity can play a crucial role in negotiations, as the proposer must offer a reasonable share of the money to the other player to avoid rejection.

Another example is the Nash bargaining solution, where two players must divide a surplus between them. The Nash bargaining solution provides a fair and efficient way to divide the surplus, based on each player’s bargaining power and outside options. The Nash bargaining solution shows that negotiations can be successful if the parties are willing to compromise and find a mutually beneficial solution.

Limitations and Criticisms of Game Theory

While game theory has many applications and insights, it also has limitations and criticisms. One limitation is the assumption of rationality, which may not hold in real-world settings where emotions, biases, and incomplete information can affect decision-making. Another limitation is the assumption of perfect information, which may not hold in complex and dynamic environments where uncertainty and ambiguity are prevalent.

Moreover, Game theory has been criticized for emphasizing equilibrium outcomes, which critics argue does not sufficiently account for the dynamics and long-term evolution of strategic interactions. Another critique of game theory is that it is abstract and formal, which some claim does not accurately reflect the complexity and variety of real-world situations.

Last words

Game theory is a powerful and adaptable instrument that helps in our understanding of strategic interactions in a variety of contexts, including politics, economics, biology, and psychology. In modern life activities like business and war, where decision-making is frequently complex and involves numerous participants with competing interests, game theory has vital implications. By learning about game theory, we can improve our strategies and policies for accomplishing our goals and objectives by gaining insights into the dynamics and results of strategic interactions.
