In parametric models a sufficient condition for local identification is that the vector of moment conditions is … the true value that are sufficient for local identification. We apply these results to obtain new, primitive … identification conditions in several important models, including nonseparable quantile instrumental variable (IV) models, single …

This paper considers nonparametric identification of a two-stage entry and bidding model for auctions which we call the …'s identification properties have not been well understood.

We study identification and estimation in first-price auctions with risk-averse bidders and selective entry, building … standard models as special cases.
