I examine the effect of competition on eBay Motors. I specify a simple model of auction choice and show that the expected transaction price falls with an increase in the number of competitors. I then test for this effect using data from 5,500 auctions for Chevrolet Corvettes. To address...

This paper analyzes a unique dataset of art auctions on eBay. We study the behavior of buyers and sellers, demand and supply, by means of a novel structural estimation approach. Our empirical framework considers the process of arrival of new bidders as well as the distribution of bidder...

This paper presents assumptions and identification results for eBay type auctions. These results are for private value auctions covering three major issues; censoring bias, auction heterogeneity and dynamic bidding. The first section of the paper presents two identification results for second...

In this paper, we develop a dynamic supernetwork framework for the modelling and analysis of supply chains with electronic commerce that also includes the role that relationships play. Manufacturers are assumed to produce homogeneous products and to sell them either through physical or...

The automated negotiation process seems to be a powerful mechanism to resolve disputes arising from Internet-based transactions. Automated negotiation is an online blind-bidding process in which an automated algorithm evaluates bids from the parties and settles the case if the offers are within...

This paper presents the results of an experiment performed to test the properties of an innovative bargaining mechanism (called automated negotiation) used to resolve disputes arising from Internet-based transactions. Automated negotiation is an online sealed-bid process in which an automated...

Internet auctions on eBay and Yahoo allow sellers to list their auctions with a Buy-Now option. In such auctions the seller sets a buy price at which a bidder may purchase the item immediately and end the auction. In the eBay version of a buy-now auction, the buy-now option disappears as soon as...
