Offline Version: PDF

Term Nash equilibrium Definition: A concept from Game Theory which establishes that a set of strategies followed by economic agents within a game is in equilibrium if, holding the strategies of all other economic agents constant, no economic agent can obtain a higher payoff by choosing a different strategy. For example, when firms operate within an oligopoly, once a Nash equilibrium has been reached, none of them will want to change their strategy because by doing it they cannot obtain a higher profit.
