Nonparametric identification of first-price auction with unobserved competition: A density discontinuity framework

  title={Nonparametric identification of first-price auction with unobserved competition: A density discontinuity framework},
  author={Emmanuel Guerre and Yao Luo},
  journal={arXiv: Econometrics},
We consider nonparametric identification of independent private value first-price auction models, in which the analyst only observes winning bids. Our benchmark model assumes an exogenous number of bidders N. We show that, if the bidders observe N, the resulting discontinuities in the winning bid density can be used to identify the distribution of N. The private value distribution can be identified in a second step. A second class of models considers endogenously determined N, due to a reserve…

Order Statistics Approaches to Unobserved Heterogeneity in Auctions

We establish nonparametric identification of auction models with continuous unobserved heterogeneity using either three consecutive order statistics of bids or two with an instrument. We then propose

Identification of Auction Models Using Order Statistics

This paper studies the identification of auction models with unobserved heterogeneity (UH) using multiple order statistics of bids and shows that models with nonseparable finite UH is identifiable using three consecutive order statistics or two consecutive ones with an instrument.

Winning by Default: Why is There So Little Competition in Government Procurement?

In government procurement auctions, eligibility requirements are often imposed and, perhaps not surprisingly, contracts generally have a small number of participating bidders. To understand the eects

Optimal Nonparametric Estimation of First-price Auctions

This paper proposes a general approach and a computationally convenient estimation procedure for the structural analysis of auctioni data. Considering first-price sealed-bid auction models within the

What Model for Entry in First-Price Auctions? A Nonparametric Approach

We develop a nonparametric approach that allows for discrimination among alternative models of entry in first-price auctions. Three models of entry are considered: those of Levin and Smith (1994),

Nonparametric Approaches to Auctions

This chapter discusses structural econometric approaches to auctions, focusing on first-price sealed-bid and ascending auctions, including extensions to Dutch auctions, Internet auctions, multi-unit auctions, and multi-object auctions.

A Nonparametric Test for Comparing Valuation Distributions in First‐Price Auctions

This article proposes a nonparametric test for comparing valuation distributions in first‐price auctions. Our test is motivated by the fact that two valuation distributions are the same if and only

First-Price Auctions with Risk-Averse Bidders

We consider first-price auctions with asymmetric independent private values and risk-averse bidders. We show that a bidder's expected equilibrium equilibrium bid strategy satisfies that her utility

Bidding for Firms: Subsidy Competition in the U.S.

In the U.S., states compete to attract firms by offering discretionary tax breaks and subsidies, but little is known about (1) the way states choose their subsidy bids, and (2) whether such subsidies
