The flip side of power

Based on power indices as well as intuition, the chairman of a committee whose vote decides in the case of a draw has more power than ordinary voters. Even more powerful are members with veto right, who can block a majority vote. We pose the question whether giving one of the players in a majority voting game more power is beneficial for the powerful individual and/or the community. We find that, in our environment, the introduction of a powerful player is efficiency-improving, but that powerful players earn less than their ordinary co-players. Our environment is a Binary Threshold Public Good game which can also be interpreted as a general non- cooperative voting game. We supplement our investigation by successfully explaining behavior as a finite mixture of mostly equilibrium strategies.
