Abstract: The existing studies suggest that sniping is an equilibrium strategy in hard-close online auctions, but not in soft-close ones. In this paper, we use a unique, large-scale data set from soft-close Overstock and hard-close eBay to document sniping phenomena under the two different closing rules. Estimation results show that sniping is prominent on both websites, but they are prevalent at different times. On eBay, sniping occurs right before the auction close, while on Overstock sniping happens predominantly in a short window of time before the triggering period, during which any additional high bid automatically extends the online auction. Furthermore, the revenue effect of sniping is significantly stronger on Overstock than on eBay.
