Power indices with threats in precoalitions

Staudacher, Jochen - 2025

We investigate power indices for simple games with precoalitions which distribute power among players in an external and an internal step. We extend an existing approach which uses the Public Good index both on the external level in the quotient game as well as on the internal level for...

Monte Carlo methods for the Shapley-Shubik power index

Ushioda, Yuto; Tanaka, Masato; Matsui, Tomomi - 2022

This paper deals with the problem of calculating the Shapley-Shubik power index in weighted majority games. We propose an efficient Monte Carlo algorithm based on an implicit hierarchical structure of permutations of players. Our algorithm outputs a vector of power indices preserving the...

Power in plurality games

Brink, René van den; Dimitrov, Dinko; Rusinowska, Agnieszka - 2024

Simple games in partition function form are used to model voting situations where a coalition being winning or losing might depend on the way players outside that coalition organize themselves. Such a game is called a plurality voting game if in every partition there is at least one winning...

Agenda-Setting Power in Legislative Bargaining

Agenda-setting power is a double-edged sword that increases the likelihood that an agent is chosen to be a proposer, but may reduce the probability that the agent is included in a winning coalition. We experimentally test the theoretical prediction of potentially negative returns to...

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.
