Within a simple setup, we show that proportional taxation is implied by three properties: efficiency, symmetry, and monotonicity. Efficiency: redistribution has no cost. Symmetry: members of the society with the same performance obtain the same reward after redistribution. Monotonicity: whenever...

The principle of weak monotonicity for cooperative games states that if a game changes so that the worth of the grand coalition and some player's marginal contribution to all coalitions increase or stay the same, then this player's payoff should not decrease. We investigate the class of values...

Within a simple setup, we show that fair redistribution of performance-based allocations implies proportional taxation. Fair redistribution is characterized by three properties: efficiency, i.e., redistribution has no cost. Anonymity, i.e., rewards after redistribution do not depend on the...
