Nash Equilibrium in Finance

Theory

Nash equilibrium, a core concept in game theory, describes a stable state in a non-cooperative game where no player has an incentive to unilaterally deviate from their chosen strategy. In finance, this theory helps model the strategic interactions between market participants, such as high-frequency traders, liquidity providers, and options market makers. Understanding the equilibrium state allows for the prediction of market behavior under specific conditions and incentive structures.
