Identification in english auctions with shill bidding
What can we learn from auction data when the seller submits shill bids to inflate the auction price? I study identification in an incomplete model of an English auction with shill bidding in the context of independent private values. I show that the distribution of valuations is partially identified (as is the optimal reserve price), and I provide bounds for the distribution of valuations that hold even when the seller is not engaging in shill bidding. I apply these results to a sample of eBay auctions.
