“…Thus, the winning bid will not be an overestimate of that bidder's true willingness to pay, but may be an underestimate 6 , to the extent that the key bidders are reactive rather than "incremental" (Zeithammer and Adams, 2010). This is of particular interest in cases like ours where the product is 5 See also Anwar et al (2006) for complications relating to the winning bid implied by cross-bidding. 6 This is even after accounting for the fact that the winning bid is the second highest valuation, not the highest.…”

The iPhone 4 was introduced into the UK market on 24 th June 2010 to significant consumer interest.This clearly exceeded supply through conventional channels, since there was very extensive activity in terms of bidding on eBay auctions for the product. We monitored all eBay transactions on the iPhone 4 for six weeks from introduction, with total transactions amounting to around £1.5m. We analyse determinants of the winning bid in terms of characteristics of the phone, the seller and the buyer. Our most notable and novel finding relative to previous studies is a very significant premium over list price being paid in almost all cases, with positive uplift factors including whether the phone was unlocked and whether it could be sold overseas. Demand fell over time, as evidenced by lower achieved prices, but the fall in price was relatively modest. A significant premium of 32GB over 16GB versions is revealed.

“…On the other hand, Anwar et al (2006) observe that bidders are less likely to bid on identical items if their respective auction end times are far apart. Hence, the time elapsed between auctions may be an important factor for price formation in sequential auctions, which calls for further studies.…”

This paper investigates two hitherto unexplored dimensions inherent in online sequential auctions, namely, how the time elapsed between the end of an auction and the end of the next one and the order of presentation on the website affect prices. Using a state-of-the-art-dataset on train-ticket auctions with a particular institutional design feature that enables a causal interpretation of these dimensions, it is demonstrated that both dimensions have a significant impact on price formation in sequential auctions.

“…Sun (2005) for example showed large price dispersion in 3,164 sequential eBay auctions for identical items. In concurrent eBay auctions, Anwar, McMillan and Zheng (2006) find that significant cross-bidding occurs and that bidders switch to lower-priced auctions. Nevertheless, not all bidders switch to lower-priced auctions and significant price dispersion may still occur in concurrent auctions.…”
