The same slump, by the way, made nonsense of much of what the equilibrium business cycle theorists were saying.
Since the development of the Nash equilibrium concept, game theorists have proposed many related solution concepts, like Pareto equilibrium, subgame perfect Nash equilibrium, Bayesian-Nash equilibrium, ε-equilibrium, correlated equilibrium, and Wardrop equilibrium [15].
He continues, "It is loosely analogous to what a game theorist would call mixed-strategy equilibrium: an approach that generates sufficient randomness (or apparent randomness) across government sources as to degrade the ability of outsiders to predict the nature and origin of any given disclosure".
In the language of the game theorists, he believed there was an equilibrium, a stable option that would maximize freedom and minimize harm.
More directly, her claim was that conventions are not merely the products of decisions of many individual people, as might be suggested by a theorist who modeled a convention as an equilibrium of an n-person game in which each player was a single person.
In subsequent years, game theorists have realized that the Nash and more general correlated equilibrium concepts can be defined entirely in terms of agents' beliefs, without recourse to mixed strategies.
To the game theorist, it is all a struggle for a Nash equilibrium – "the best that each party can get, conditional on the other trying to get the best they can also".
How can the non-psychological game theorist understand the concept of an NE that is an equilibrium in both actions and beliefs?
Game theorists have been good at explaining the intricacies underlying strategic interdependence and producing ever more refined concepts of equilibrium but less adept at giving governments and firms practical advice.Even that criticism, though, is weakening.
Starting from Schelling (1960), several game theorists have conjectured that payoff equity might facilitate coordination in normal-form games with multiple equilibria – the more equitable equilibrium might be selected either because fairness makes it focal or because many individuals dislike payoff inequities, as abundant experimental evidence suggests.
