学区和其他机构在分配物品时不使用转移,往往依赖于只引起代理人顺序偏好的机制。本说明表明,仅引发序数偏好所造成的福利损失可以是任意大的。
School districts and other institutions allocating objects without the use of transfers tend to rely on mechanisms that only elicit agents’ ordinal preferences. The present note shows that the welfare loss imposed by only eliciting ordinal preferences can be arbitrarily large.
