Hello. We are 5th year Mathematics PhD students at UCSD. As part of a project in human game theory, Penny Auctions were studied at ArrowOutlet.com. If you do not know what a Penny Auction is, [click here] before proceeding.
During November and December 2011, the behavior of every user was monitored and the bidding history of every auction was recorded. Our computers worked over 2000 hours and analyzed over 500 Megabytes of data! Sadly, this work can not be used to study human behavior because the majority of users at ArrowOutlet.com are in fact robots.
We have decided to make this data public and anyone who would like to use this information can. In November and December 2011, the majority of bids at ArrowOutlet.com were placed by robots and the majority of auctions were won by robots. As a result, 95% of all humans who participated at ArrowOutlet.com in November or December 2011 lost money overall. In these 2 months, human net loss totaled over $260,000.00.
