What is Nash equilibrium for dummies?

What is Bayesian Nash equilibrium?
A Bayesian Nash equilibrium (BNE) is defined as a strategy profile that maximizes the expected payoff for each player given their beliefs and given the strategies played by the other players.
Is Nash equilibrium a dominant strategy?
A dominant strategy is a type of Nash equilibrium. A dominant strategy is a strategy which results in the best payoff for a player no matter what the other firm does but a Nash equilibrium represents a strategy which maximizes payoff given what the other player would do.Mar 27, 2019
Is Nash equilibrium good for society?
By mathematically proving that there exists at least one such equilibrium point in any such game, Nash helped economists, politicians, bureaucrats, and business strategists understand the world around us in a better way. It formed the basis of many strategies we see around the world.Jul 16, 2014
