Abstract: Retailers are increasingly exploiting online auction markets as an effective and low cost distribution channel for disposing large inventories. To clear large inventories, these sellers conduct many auctions selling identical items over a period of time, creating an auction market where bidders have opportunities to sequentially participate in many auctions to find bargains. We observe that despite having an opportunity to participate in future auctions, after trying and being unsuccessful, many bidders leave the auction market. Since bidders in this unique market setting can observe and estimate market supply, demand and competition, we posit that this market information influences their decision to leave or participate in future auctions. We empirically detect and investigate the effect of market supply, demand and competition on bidder attrition in these markets.
