We prove two results on the generic determinacy of Nash equilibrium in voting games. The first one is for negative plurality games. The second one is for approval games under the condition that the number of candidates is equal to three. These results are combined with the analogous one obtained...

We construct a Cournot model in which firms have uncertainty about the total number of firms in the industry. We model such an uncertainty as a Poisson game and we characterize the set of equilibria after deriving some novel properties of the Poisson distribution. When the marginal cost is...
