卖方剩余,供应商提供某商品所付出的最低成本与实际获得的收益的差额。比如,供应商或者生产商提供某商品的成本为5元,而他在市场交易中实际获得了8元,那么卖方剩余就是3元。
然而,一般来说,歧视性的信息披露政策有可能对于卖方而言是最优的,因为它可以减少信息租金而对交易剩余的影响不大。
In general, however, discriminatory disclosure can be optimal, because it reduces the information rent accrued to private types of the buyer without much impact on the trade surplus.
买方不承担由于卖方不完善的材料管理习惯而引起的剩余的订购材料或加工材料而产生的费用。
Buyer shall not be liable for Seller's excess material ordered or manufactured that is attributable to Seller's poor material management practices.
