The role of information in auctions
这篇综述回顾了Engelbrecht-Wiggans等人（1983）和Milgrom与Weber（1982a）关于信息在拍卖中作用的开创性贡献，并展示了这些见解如何应用于信息结构内生决定的灵活信息获取拍卖文献。
This review discusses the seminal contributions of Engelbrecht-Wiggans et al. (1983) Milgrom and Weber (1982a) to the literature that studies the role of information in auctions. We describe the results in these papers and present several extensions. Much of the earlier literature on auctions takes the information environment as exogenous. The extensions that we present will demonstrate how the insights of Engelbrecht-Wiggans et al. (1983) and Milgrom and Weber (1982a) apply to the more recent literature on flexible information acquisition in auctions where the information structure is endogenously determined in equilibrium.
