本文研究机制设计中转移支付可观察性对均衡结果的影响,证明公开转移支付可任意近似隐藏转移支付的均衡结果,从而合理化转移支付隐藏的常见假设。
AI 中文摘要
我们研究了一种机制,其中参与者的偏好既取决于物品分配,又取决于第三方对私人信息的信念。该机制决定了分配、转移支付,并向二级市场发送信号。我们比较了两种信息环境:(i)私人转移支付,即二级市场观察到分配和信号;(ii)公开转移支付,即转移支付是公开可观察的。我们的主要结果表明,任何在隐藏转移支付下可实现的均衡结果,都可以通过公开转移支付任意近似。因此,转移支付的可观察性至多产生可忽略的信息扭曲,并有助于合理化转移支付对二级市场保持隐藏这一常见假设。
英文摘要
We study mechanisms in which agents' preferences depend both on an object allocation and on a third party's beliefs about private information. A mechanism determines an allocation, transfers, and sends signals to the aftermarket. We compare two informational environments: (i) private transfers, where the aftermarket observes allocations and signals, and (ii) public transfers, where transfers are publicly observable. Our main result shows that any equilibrium outcome implementable with hidden transfers can be approximated arbitrarily well with public transfers. Thus, transfer observability generates at most a vanishing informational distortion and helps rationalize the common assumption that transfers remain hidden from aftermarkets.
