We study the efficient computation of power indices for weighted voting games with precoalitions amongst subsets of …-of-the-art algorithms for computing the Banzhaf and Shapley-Shubik indices for weighted voting games, we present a framework for fast … algorithms for the three most common power indices with precoalitions, i.e., the Owen index, the Banzhaf-Owen index and the …

Weighted committees allow shareholders, party leaders, etc. to wield different numbers of votes or voting weights as …

In a model of simultaneous voting, Feddersen and Pesendorfer (1998) consider the possibility that jurors vote … that those unintuitive predictions also hold with sequential voting. In this paper, we report paired experiments with … sequential and simultaneous voting under unanimity and majority rule. Observed behavior varies significantly depending on whether …

at a particular aspect, the power distribution in the Council of the European Union. Using the Shapley-Shubik power index …, we calculate the member states' powers with and without the United Kingdom and update earlier power forecasts using the … Eurostat's latest population projections. There is a remarkably sharp relation between population size and the change in power …

voting experiments. To evaluate the effect of complexity we adopt a level-k reasoning model concept. This model by Nagel [1 …, increasing payoff amounts does promote more strategic behavior in a significant manner. Our results show with complex voting …

knowledge of the preference profile of the electorate, and preference cycles are limited. Both papers devise voting systems …

on the effect of party polarization on the electoral prospects of a new centrist candidate through strategic voting …

We study strategic voting in a setting where voters choose from three options and Condorcet cycles may occur. We … strategic voting in our experiment compared to the homogenous preference case that we study in a companion paper. Both … aggregate distribution of preferences seems to be the element that best explains observed differences in voting behavior …

This paper studies how the cost of delay and voting order affect agents' decisions in a unanimity voting mechanism …
