1;-stability of Symmetric and of Quota Games'
We shall always take I, to be the first n integers, i.e., a labeling of the players. The terms S-equivalence, essential and inessential games, in~putations, and coalitions will have their usual meanings [2]; however, we shall let the word "game" mean "essential game" except when it is prefixed by "inessential". The notation used will be standard, except that we shall write z(T) for E l t T x z ...
متن کاملManipulating the Quota in Weighted Voting Games
Weighted voting games provide a popular model of decision making in multiagent systems. Such games are described by a set of players, a list of players’ weights, and a quota; a coalition of the players is said to be winning if the total weight of its members meets or exceeds the quota. The power of a player in such games is traditionally identified with her Shapley– Shubik index or her Banzhaf ...
متن کاملManipulation of Weighted Voting Games and the Effect of Quota
The Shapley-Shubik, Banzhaf, and Deegan-Packel indices are three prominent power indices for measuring voters’ power in weighted voting games. We consider two methods of manipulating weighted voting games, called annexation and merging. These manipulations allow either an agent, called an annexer to take over the voting weights of some other agents, or the coming together of some agents to form...
متن کاملStatic Stability in Games
Static stability of equilibrium in strategic games differs from dynamic stability in not being linked to any particular dynamical system. In other words, it does not make any assumptions about off-equilibrium behavior. Examples of static notions of stability include evolutionarily stable strategy (ESS) and continuously stable strategy (CSS), both of which are meaningful or justifiable only for ...
متن کاملEvolutionary Stability in Asymmetric Games *
We examine dynamic models of evolutionary selection processes on asymmetric two-player games. Conditions are established under which dynamic selection processes will yield outcomes that respect iterated strict dominance. The addition of a stability requirement ensures that outcomes will be Nash equilibria. However, we find that stable outcomes need not respect weak dominance, and hence need not...
