Indices that evaluate the distribution of power in simple games are commonly required to be monotonic in voting weights when the game represents a voting body such as a shareholder meeting, parliament, etc. The standard notions of local or global monotonicity are bound to be violated, however,...

Members of a shareholder meeting or legislative committee have greater or smaller voting power than meets the eye if the nucleolus of the induced majority game differs from the voting weight distribution. We establish a new sufficient condition for the weight and power distributions to be equal,...

For one of the most prominent solution concepts for cooperative TU games, we show that in the weighted case the nucleolus tends to the weights as the number of players increases under very mild conditions. We give a sufficient characterization for the case of coincidence between weights and...
