An inequality game is an asymmetric 2 × 2 coordination game in which player 1 earns a substantially higher payoff than player 2 except in the inefficient Nash equilibrium (NE). The two players may have either common or conflicting interests over the two NE. This paper studies a redistribution scheme which allows the players to voluntarily transfer their payoffs after the play of an inequality game. We find that the redistribution scheme induces positive transfer from player 1 to player 2 in both common- and conflicting- interest games, and is particularly effective in increasing efficient coordination and reducing coordination failures in conflicting-interest games. We explain these findings by considering reciprocity by player 1 in response to the sacrifice made by player 2 in achieving efficient coordination in conflicting-interest games.

不等式博弈是一种非对称的 2 × 2 协调博弈，其中除了低效的纳什均衡 (NE) 外，参与者 1 获得的收益远高于参与者 2。两个参与者可能在两个 NE 上有共同或冲突的利益。本文研究了一种重新分配方案，该方案允许参与者在进行不平等博弈后自愿转移他们的收益。我们发现，再分配方案在共同利益博弈和利益冲突博弈中都诱导了从参与者 1 到参与者 2 的正向转移，并且在提高利益冲突博弈中的有效协调和减少协调失败方面特别有效。我们通过考虑参与者 1 的互惠来解释这些发现，以响应参与者 2 在利益冲突博弈中实现有效协调的牺牲。
