Nash Equilibrium Explained

Nash Equilibrium is a fundamental concept in game theory where players reach a strategy set where no player can benefit by unilaterally changing their strategy, given the strategies of others. It showcases the importance of mutual trust and strategic decision-making in competitive environments, as seen in scenarios like the Prisoner's Dilemma, where players may end up with suboptimal outcomes despite having rational choices. Understanding Nash Equilibrium is crucial for analyzing behaviors in oligopolies and various economic interactions, making it a key topic in microeconomic studies.
