This paper investigates the suitability of apportionment methods based on the idea of preserving the coalition function of the simple game represented by the populations of the states. The results show that an apportionment method which satisfies desirable properties such as population...

We introduce the prediction value (PV) as a measure of players' informational importance in probabilistic TU games. The latter combine a standard TU game and a probability distribution over the set of coalitions. Player i's prediction value equals the difference between the conditional...

We use the citizen-candidate model to study electoral outcomes under the Alternative Vote rule, a voting method often proposed as a replacement to the prevalent Plurality rule. We show that, like the Plurality rule, the Alternative Vote rule deters multiple candidate clusters and the presence of...

Political and economic institutions are typically governed by committees that face the challenge to reconcile the preferences of their members. How should decision rules be designed to generate fair and sustainable agreements, for example if committee members represent groups of different sizes?...

We suppose that players in a cooperative game are located within a graph structure, such as a social network or supply route, that limits coalition formation to coalitions along connected subsets within the graph. This in turn leads to a more general study of coalitional games in which there are...

This paper surveys research of lab experiments on voting games, focusing on six areas that have received much attention in the last few decades: (i) costly voting in elections with two alternatives; (ii) (other) collective action problems; (iii) elections with more than two alternatives; (iv)...

There are situations in which competitors ally to pursue a common objective. This simultaneous presence of cooperation and competition is called coopetition and we study it theoretically and experimentally in a group contest setup. More concretely, we analyze a group contest with a new sharing...
