Preferred suppliers in auction markets
研究买方与首选供应商之间的协议如何增加双方联合剩余，取决于买方能否设计最终采购拍卖规则。
This article examines agreements between a buyer and one of the suppliers which increase their joint surplus. The provisions of such agreements depend on the buyer's ability to design the rules of the final procurement auction. When the buyer does not have this ability, their joint surplus can be increased by an agreement which grants to the preferred supplier a right of first refusal on the lowest price from the other suppliers. When the buyer has this ability, their joint surplus can be maximized by a revelation game for the cost of the preferred supplier and a reserve price based on that cost.
