A Consistent Nonparametric Test of Affiliation in Auction Models
نویسندگان
چکیده
We propose a new nonparametric test of affiliation, a strong form of positive dependence with independence as a special, knife–edge, case. The test is consistent against all departures from the null of affiliation, and its null distribution is standard normal. Like most nonparametric tests, a sample–size dependent input parameter is needed. We provide an informal procedure for choosing the input parameter and evaluate the test’s performance using a simulation study. Our test can be used to test the fundamental assumptions of the auctions literature. We implement our test empirically using the Outer Continental Shelf (OCS) auction data.

Are There Common Values in First-Price Auctions? A Tail-Index Nonparametric Test
We develop a consistent nonparametric test of common values in first-price auctions and apply it to British Columbia Timber Sales data. The test is based on the behavior of the CDF of bids near the reserve price. We show that the curvature of the CDF is drastically different under private values (PV) and common values (CV). We then show that the problem of discriminating between PV and CV is eq...
متن کاملNonparametric Approaches to Auctions∗
This chapter discusses structural econometric approaches to auctions. Remarkably, much of what can be learned from auction data can be learned without restrictions beyond those derived from the relevant economic model. This enables us to take a nonparametric perspective in discussing how the structure of auction models can be combined with observables to uncover (or test hypotheses about) primi...
متن کاملImposing and Testing for Monotonicity Nonparametrically in First Price Auctions
Monotonicity of the equilibrium bidding strategy is a key property of structural auction models. Traditional nonparametric estimators provide a flexible means of uncovering salient features of auction data, but do not formally impose the monotonicity assumption that is inherent in the models they are trying to estimate. Here we develop a nonparametric estimator which imposes the monotonicity as...
متن کاملStructural estimation ofthe affiliated private value auction nlodel
We consider the structural estimation of the affiliated private value (APV) model in first.:p~ice sealed-bid auctions. The model allows for bidders' individual efficiencies and opportunity costs, while permitting dependence among bidders' private values through affiliation. We establish the non parametric identification ofthe APVmodel, characterize its theoretical restrictions, and pro pose a ...
متن کاملNonparametric Identification and Estimation of Pure Common Value Auction Models with an Application to U.S. OCS Wildcat Auctions∗ (Job Market Paper)
Although pure common value auction models have broad applicability in empirical analysis, nonparametric identification and structural estimation remain challenging in these contexts. In this paper, we establish novel identification results for both the first-price and the second-price sealed-bid auction models in the pure common value framework. We show that the joint distribution of private si...
