Group Decision-Making and the Winner's Curse

这是亚利桑那州立大学和亚利桑那大学的合作项目，旨在研究拍卖投标中的群体决策。现有数据表明，集体竞标尤其容易受到“赢家诅咒”现象的影响，即在拍卖中获胜的竞标者倾向于系统性地为所购物品支付过高的价格。PIs建议运行先导实验来分析个体信息在群体成员中的作用，并探索群体的替代决策规则。% '¢-烧烧ÕÁ│¥¥？¥©Á <e:2>╣Á¾││¾Á¾©Á？_Á？¥©Á¥Á Á││Â？.cn .cn .cn .cn .cn .cn .cn .cn .cn .cn .cn .cn .cn .cn .cn .cn .cn¢¥吗?_/ ‘¢’¢¥Á_/¥╣│/%% '¥？？_┐│©?<s:1>¥©Á╣¥Á_││©/¢Á¼©Á &amp；¿¢？¢¥吗?╝┐║╣% ?¥Á Á _Á￥？//% '：Á¥©Á ？% ?Â辖内╣贪欲→贪欲→贪欲→贪欲→贪欲→Â？/ _ ?一个╝吗?- <s:2> _Á_烧烧Á¾/│Á %？0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00╝┐%¢一个吗?￥©Á À ？┐║

This collaborative project between Arizona State University and the University of Arizona proposes to study group decision making for bidding in auctions. Existing data suggest that group bids are particularly subject to the winner's curse phenomenon - the tendency for winning bidders in auctions to pay systematically too much for the item purchased.. The PIs propose to run pilot experiment to analyze the role of individual information among group members and explore alternative decision rules for the group. %` ¢┐▓ÕÁ│¥ ¥? ¥©Á ┴╣Á╝ ¢ │┐╝¢Á ║©Á?_Á? ¥ ©Á ¥Á┤Á│` Â?╝ ┴╣╣À ▓╣┤┤Á╝¢ ╣ /┐│¥╣?¢ ¥? ║/` ¢`¢¥Á_/¥╣│/%%` ¥?? _┐│© Â?╝ ¥©Á ╣¥Á_ ║┐╝│©/¢Á┤ ¼©Á &amp;¿¢ ║╝?║?¢Á ¥? ╝┐ ║╣%?¥ Á┬║Á╝╣_Á¥ ¥?//%`:Á ¥©Á ╝?%Á ? ╣┤╣└╣┤┐/% ╣Â?╝_/¥╣? /_?À À╝?┐║ _Á_▓Á╝¢ /┤ Á┬║%?╝Á /%¥Á╝/¥╣└Á ┤Á│╣¢╣? ╝┐%Á¢ Â?╝ ¥©Á À ╝?┐║
