Optimal information revelation in procurement schemes
买家拥有供应商匹配度的私人信息，研究发现同时搜索时分享信息能加剧价格竞争，但额外信息无益；顺序搜索时信息揭示从不最优。
A buyer procuring a single input possesses private information about each potential supplier's degree of fit with the buyer's needs. She can search among suppliers either sequentially or simultaneously. As long as the distribution of the fit parameter is not overly skewed to the left, sharing information with suppliers yields intensified price competition under simultaneous search. Moreover, the buyer cannot benefit by providing suppliers additional information beyond their own fitness parameter. Information revelation is never optimal with sequential search.
