报告内容摘要:  This paper approaches the classic implementation problem with interdependent valuations in a new way. Instead of exploring conditions on preferences, we introduce a semi-exclusive information structure that can help implement efficient or inefficient social choice rule in generic environments. Semi-exclusive information allows agents to observe noisy signals about their opponents’ payoff types. This piece of information can provide a tool for the designer to verify other agents’ private information. Thanks to this tool, we could restore the implementation of efficiency that would not have been possible following the routine method of finding global or local sorting conditions. We study generic environments that include settings with preferences not satisfying “single crossing conditions,” or other similar sorting conditions. The role of semi-exclusive signal is targeted to align the incentive constraints. We explore the implementability of efficient rule and other properly specified rules both when this information structure is static and when it is dynamic. While both setups can implement general allocation rules, the static setting sheds light on Crémer and McLean (1985,1988)’s utilization of correlation and the dynamic setting steps away from Crémer and McLean’s world and explores the correlation after the allocation decisions.
