Strategic behaviour in competing auctions evidence on ebay

This paper provides an empirical research about bidding behaviour and final price evolution in competing auctions. The results obtained have been supported with online auctions data from eBay. About bidding behaviour, we found that bidders use cross-bidding (bidding between competing auctions) and sniping (last minute bidding on an item) strategies to maximise their profits. Moreover, no price decline anomaly was found although there was price dispersion amongst homogeneous lots.
