Infinite Players, Infinite Possibilities: Game Theory Unlocks New Frontiers for Society
The article discusses how Nash equilibria in games with many players can be understood by looking at equilibria in smaller games. They show that a strategy is a Nash equilibrium in a game with many players if there exists a sequence of smaller games where it is also an equilibrium. This applies when most players are optimizing, and certain conditions are met. The findings suggest that studying equilibria in smaller games can help understand strategic behavior in larger economies.
