Incomplete Information Equilibria
September 7th, 2005
Equilibria when actions are taken after knowing own type but not the others’:
- Dominant: Best response to every collection of actions of the other players knowing all types (ex post).
- Ex post: Best response to every equilibrium actions of the other players knowing all types (ex post).
- Bayesian Nash: Best response to every equilibrium actions of the other players knowing own type (interim).
- Ex ante: Best response to every equilibrium actions of the other players knowing no types (ex ante).
Dominant => ex post => Bayesian Nash (interim) = ex ante almost surely.
