Key Concepts

Game Theory

Game theory is the study of strategic decision making, providing a framework for understanding how rational individuals make choices in situations where the outcome depends on the actions of all involved participants. It underpins the analysis of competitive and cooperative interactions, revealing how individual incentives can lead to different collective outcomes.

Prisoner’s Dilemma

The Prisoner’s Dilemma is a quintessential model in game theory that demonstrates the conflict between individual rationality and collective benefit. It shows that even when mutual cooperation would yield a better collective outcome, self-interested strategies (defection) can lead each participant to a worse result, highlighting the tension between personal incentives and group well?being.

Nash Equilibrium

Nash Equilibrium is a concept where each player's strategy is optimal given the strategies chosen by others, meaning no one can benefit by unilaterally changing their action. In the context of the Prisoner’s Dilemma, the equilibrium occurs when all individuals pursue self-interest, even though this results in a suboptimal outcome compared to mutual cooperation.

Dominant Strategy

A dominant strategy is one that results in a better payoff for a player regardless of what the other players do. In the Prisoner’s Dilemma, defecting is considered the dominant strategy because it provides a better individual outcome irrespective of the opponent’s decision, even though a cooperative approach would lead to a collectively more beneficial result.
