This paper studies the nonparametric identification of the first-price auction model with risk averse bidders within the private value paradigm. First, we show that the benchmark model is nonindentified from observed bids. We also derive the restrictions imposed by the model on observables and...

Collusion and heterogeneity across firms may introduce asymmetry in bidding games. A major difficulty in asymmetric auctions is that the Bayesian Nash equilibrium strategies are solutions of an intractable system of differential equations. We propose a simple method for estimating asymmetric...

Under multiplicative separability of the cost function, this paper investigates the identification of the procurement model. Moreover, we characterize the model restrictions on observables and show its observational equivalence to one where the function of private information is the identity.
