內(nèi)容摘要：
In common-value second-price auctions of items with uncertain value, we examine the role of fixed-fee return policies that resemble many situations in real business practice: e.g., deposits in oil field auctions, mineral and gas right auctions, spectrum auctions, and money-back guarantees with fixed shipping and handling charges in eBay auctions. Theory makes the prediction that a more generous return policy will hurt the winning bidder by eroding consumer surplus through higher bids. Theory also demonstrates that the seller’s revenue increases as the handling fee for returning the auctioned item decreases, but remains positive. For free returns, there are multiple equilibria, all involving zero consumer surplus for the winning bidder, but with different implications for sellers. In our experimental setting, items may have a high value of 100 or a low value of 0 with an a priori 50% probability of each outcome. There are experimental four treatments: No Return (NR), High Fee (HF), Low Fee (LF) and Free Return (FR). We observe that bids increase and bidders’ earnings decrease when the handling fee decreases as predicted. However, we also observe that in the FR treatment many bidders bid above the highest possible value and subsequently return the item regardless of the revealed value. While this is consistent with equilibrium behavior, it is an equilibrium that is not optimal for the seller.
