There are many situations in which different groups make collective decisions by committee voting, where each group is represented by a single person. Theoretical concepts suggest how the voting systems in such committees should be designed, but these abstract rules can usually not be...

There are many situations in which different groups make collective decisions by committee voting, with each group represented by a single person. A natural question is what voting system such a committee should use. Concepts based on voting power provide guidelines for this choice. The two most...

Power index research has been a very active field in the last decades. Will this continue or are all the important questions solved? We argue that there are still many opportunities to conduct useful research with and on power indices. Positive and normative questions keep calling for...

Among the wide variety of voting power indices, the public good index (PGI) is one of the less well-known ones. Holler (forthcoming) posits hypotheses about why this is the case. In response to these hypotheses, I share a few thoughts about voting power in general and about the popularity of the PGI

There are many situations where different groups make collective decisions by voting in an assembly or committee in which each group is represented by a single person. There is a great deal of theoretical, normative literature on the question of what voting system such an assembly should use,...

There are many situations in which different groups make collective decisions by committee voting, with each group represented by a single person. This paper is about two closely related problems. The first is that of how to measure the inequality of a voting system in such a setting. The second...
