Axiomatic bargaining theory: New wine from old bottles
用五个经典公理（对称性、弱帕累托最优、受限单调性、中点支配、超可加性）刻画了一个讨价还价解，该解先给每个玩家其乌托邦点的n分之一，再平分剩余部分。
Five classical and uncontroversial axioms—symmetry, weak Pareto optimality, restricted monotonicity, midpoint domination, and superadditivity—characterize a bargaining solution. It assigns to each player their midpoint, that is, the n -th share of their utopia point, and equally divides what remains.
