INFORMATION REVELATION AND BUYER PROFITS IN REPEATED PROCUREMENT COMPETITION*
研究在重复采购中，买方揭示卖方行为信息对采购成本的影响，发现揭示最少或最多信息时价格最低，揭示中等信息时价格更高。
I investigate how procurement costs are affected by the information that buyers reveal about sellers' behavior, in a setting with two sequentially offered contracts for which a seller's privately known costs are identical. Expected prices are lowest when sellers learn nothing until all contracts are allocated, are higher when they learn all sellers' price offers as contracts are allocated, and typically are even higher when they learn only the winner's identity, or the winner's identity and price offer. The results suggest that buyers engaged in repeated procurement may pay less by revealing minimal or extensive information, rather than an intermediate amount.
