We propose a semiparametric estimator within the class of indirect methods. Specifically, we model private valuations through a set of conditional moment restrictions. Our econometric model calls for a two step procedure. In the first step we recover a sample of pseudo private values while using...

Estimating bidders’ risk aversion in auctions is a challeging problem because of identification issues. This paper takes advantage of bidding data from two auction designs to identify nonparametrically the bidders’ utility function within a private value framework. In particular, ascending...
