Internet auctions have recently gained widespread popularity and are one of the most successful forms of electronic commerce. We examine a unique dataset of eBay coin auctions to explore the determinants of bidder and seller behavior. We first document a number of empirical regularities. We then specify and estimate a structural econometric model of bidding on eBay. Using our parameter estimates from this model, we measure the extent of the winner's curse and simulate seller revenue under…

Determinants and Effects of Reserve Prices in Auctions Empirical Evidence from Online Gaming ∗
We use a unique hand collected data set of 6,258 auctions from the online football manager game Hattrick to study determinants and effects of reserve prices. We find that chosen reserve prices…
Cyberspace Auctions and Pricing Issues: A Review of Empirical Findings
April 2002 This article surveys empirical findings from recent studies of Internet auctions and summarizes the economic insights gained from these findings. The main questions addressed in this…
Experimental evidence on the endogenous entry of bidders in internet auctions
This paper tests the empirical predictions of recent theories of the endogenous entry of bidders in auctions. Data come from a field experiment, involving sealed-bid auctions for collectible trading…
Reserve Price Effects in Auctions: Estimates from Multiple RD Designs
We present evidence from 260,000 online auctions of second-hand cars to identify the impact of public reserve prices on auction outcomes. We exploit multiple discontinuities in the relationship…
Competition, Endogeneity and the Winning Bid: An Empirical Analysis of Ebay Auctions
TLDR
Using a dataset of Texas Instruments (TI) calculator auctions on eBay, the impact of the number of bidders on the winning bid is estimated and a novel instrumental variable, the closing interval between successive auctions is introduced.
Optimal Reservation Prices and Superior Information in Auctions with Common-Value Elements: Evidence from Field Data
In an action the seller selects a reservation price to maximize expected revenue. Theory suggests that in some cases the seller can increase his expected revenue by raising his reservation price…
Empirical Implications of Equilibrium Bidding in First-Price, Symmetric, Common Value Auctions
This paper studies federal auctions for wildcat leases on the Outer Continental Shelf from 1954 to 1970. These are leases where bidders privately acquire (at some cost) noisy, but equally…
The Role of Information in eBay Auctions
Using a unique eBay dataset of all auctions over a 5-month period of 5 similar tripods from one seller, we explore the determinants of final winning price. Previous literature has indicated…

This paper proposes a convenient estimation method for the empirical study of auction models. The authors focus on first-price sealed-bid and descending auctions within the private value paradigm.…

Reputation in Auctions: Theory, and Evidence from Ebay
Employing a procedure suggested by a simple theoretical model of auctions in which bidders and sellers have observable and heterogenous reputations for default, we examine the effect of reputation on…
Equilibrium in Auctions with Entry

Increasing Competition and the Winner's Curse: Evidence from Procurement

Competition among Sellers Who Offer Auctions Instead of Prices
In this paper we study a large market in which sellers compete by offering auctions to buyers instead of simple fixed price contracts. Two variants of the model are studied. One extends a model first…
Partial Pooling at the Reserve Price in Auctions with Resale Opportunities
TLDR
Two features common to many auctions are the use of reserve prices and the existence of secondary markets for the goods being sold; the optimal reserve price depends not only on the joint distribution of bidders' information before and after the auction, but also on how surplus is divided in the secondary market.
Mechanism Design by Competing Sellers
A dynamic model with many sellers and buyers is constructed. Agents failing to trade may trade in the next period. An equilibrium is found where sellers hold identical auctions and buyers randomize…

With internet commerce, a buyer cannot directly examine the product and so must rely upon the accuracy and reliability of the seller in deciding whether and how much to bid. In this setting, the…
