  • Number of bidders.  The number of prior bidders increases a single bidders valuation for an item. 
  • Previous purchases have no effect.  The price a bidder is willing to pay is not affected by prices they have previously paid for an this item
  • Information has a large effect.  Unsurprisingly, prices is effected by description length and the presence of a picture
  • Weekend effect.  Bidders tend to pay more for the same items at the weekend.  The theory here is that the buyers have more time to make a
  • Reputation has little effect.  This study found that feedback had little effect, something which disagrees with other studies.

Implications
