The collection of measures could represent the beliefs of agents about the state of the world, and the aggregate would then represent the beliefs of the population. Individual...

We show that in quasisupermodular games that satisfy strict single crossing property the least and greatest undominated Nash-equilibrium can be reached by iteratively eliminating dominated strategies. In the first round all weakly dominated strategies are eliminated. In the successive rounds all...
