1. to more realistic discrete-step functions, showing that in such case only upper and lower bounds on private valuations can be identified, which he does by using the previously methodology on Czech bills auctions. 24 Laffont and Vuong (1996) argue that common value models are observationally equivalent to an affiliated private value model unless there are exogenous variations that allow for identification. Horta�su and Kastl (2012) proposes an identification based on dealers observations of their costumers bids using discriminatory Canadian treasury auctions, while Horta�su, Kastl, and Zhang (2017) use uniform U.S. treasury auctions.
