Bayesian foundations of Nash equilibrium behaviour
1986-04-01This is part of a larger project to investigate the Bayesian foundations of non-cooperative solution concepts. Elsewhere Bernheim and Pearce prove that common knowledge of Bayesian rationality is not enough to justify the ... -
The Bayesian Foundations of solution concepts of games
1987We transform a non co-operati ve game into a -Bayesian decision problem for each player where the uncertainty faced by a player is the strategy choices of the other players, the pr iors of other players on the choice of ... -

The consistency of welfare judgments with a representative consumer
1988It is common practice to use the representative consumer hypothesis without specifically assuming any of the sufficient conditions under which one will exist. We show, first, that it is possible for the utility of the ... -
