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 …

This paper deals with the problem of calculating the Shapley-Shubik power index in weighted majority games. We propose … outputs a vector of power indices preserving the monotonicity, with respect to the voting weights. We show that our algorithm …

of social life: hierarchy and power asymmetry. While recent accounts posit that hierarchies can reduce within …-group conflict, individuals who possess high rank or power tend to show less cooperation. How, then, is cooperation achieved within … groups that contain power asymmetries? To address this question, the present research examines how relative power affects …

We study a model in which agents endowed with power compete for a divisible resource by forming coalitions with other … agents. The coalition with the greatest power wins the resource and divides it among its members via proportional sharing. We …
