Analyzing Power in Weighted Voting Games with Super-Increasing Weights
Weighted voting games (WVGs) are a class of cooperative games that capture settings of group decision making in various domains, such as parliaments or committees. Earlier work has revealed that the effective decision making power, or influence of agents in WVGs is not necessarily proportional to their weight. This gave rise to measures of influence for WVGs. However, recent work in the algorit...
متن کاملShapley Values in Weighted Voting Games with Random Weights
We investigate the distribution of the well-studied Shapley–Shubik values in weighted voting games where the agents are stochastically determined. The Shapley-Shubik value measures the voting power of an agent, in typical collective decision making systems. While easy to estimate empirically given the parameters of a weighted voting game, the Shapley values are notoriously hard to reason about ...
متن کاملVoting Power in Weighted Voting Games: A Lobbying Approach by
We report experiments on the following lobbying game. Two lobbyists have identical budgets and simultaneously distribute them across voters in a legislature. Each voter votes for the lobbyist who pays them most and the lobbyist who receives most votes wins a prize. Taking the share of the budget distributed to a voter as a measure of the voter‟s voting power we investigate how voting power vari...
متن کاملComputing voting power in easy weighted voting games
Weighted voting games are ubiquitous mathematical models which are used in economics, political science, neuroscience, threshold logic, reliability theory and distributed systems. They model situations where agents with variable voting weight vote in favour of or against a decision. A coalition of agents is winning if and only if the sum of weights of the coalition exceeds or equals a specified...
متن کاملMonotonicity of power in weighted voting games with restricted communication
Indices that evaluate the distribution of power in simple games are commonly required to be monotonic in voting weights when the game represents a voting body such as a shareholder meeting, parliament, etc. The standard notions of local or global monotonicity are bound to be violated, however, if cooperation is restricted to coalitions that are connected by a communication graph. This paper pro...
