An Empirical Analysis of Jump Bidding in Internet Auctions

et

This paper attempts to shed an empirical light on so-called jump bidding in ascending auctions. There is a jump when a participant in an auction outbids the last proposal by more than what is required by the rule of the auction. Using a data set from eBay, we find that the initial price, the selling price and the average degree of participant expertise are the main drivers of jump bidding.
