On the uniqueness of Nash equilibrium in discontinuous ordinal and normal form games
- 65 Downloads
Our aim is to investigate the existence and uniqueness of Nash equilibrium in the general setting of ordinal games. Using a new property, called strict condition, we identify a class of discontinuous games where there exists a unique Nash equilibrium if and only if the single deviation property is satisfied.
