An increasing number of retailers use online auctions to clear off their sizable inventories of various items. To clear large inventories, these sellers conduct many auctions of identical items one after another, termed as sequential online auctions. Interested bidders participate in many auctions to find a good bargain. There has been a host of studies on bidders' behavior but none has addressed the underlying reasons of a bidder's decision to stop participating before winning. This phenomenon of bidders' attrition is of interest to auctioneers, as these bidders determine the competition and demand in an auction sequence. Our analysis finds that longer auction duration, higher lot size per auction and bidders' prior wins affect bidders' attrition in sequential online auctions.
