本文研究了事前对称代理双边贸易中的固定价格机制。我们证明最优价格特别简单:它完全等于代理商分布的平均值。最优价格保证最坏情况下的表现至少是第一最佳贸易收益的 1/2,无论代理的分布如何。我们还表明,最坏情况下的性能随着代理数量的增加而提高,并且对各种扩展具有鲁棒性。我们的结果为尺寸发现的固定价格机制的广泛使用提供了解释,例如在后处理机制和暗池中。
This paper studies fixed-price mechanisms in bilateral trade with ex ante symmetric agents. We show that the optimal price is particularly simple: it is exactly equal to the mean of the agents' distribution. The optimal price guarantees a worst-case performance of at least 1/2 of the first-best gains from trade, regardless of the agents' distribution. We also show that the worst-case performance improves as the number of agents increases, and is robust to various extensions. Our results offer an explanation for the widespread use of fixed-price mechanisms for size discovery, such as in workup mechanisms and dark pools.
