Shill bidding and information in eBay auctions: A Laboratory study

In online auction platforms, like eBay, sellers have frequently been observed to bid on their item to artificially increase its price, and this is known as shill bidding. We represent the eBay auction in a sequential auctions environment using lab experiments and study the behavioral consequences of...
