Important alert: May 9, 2012 11:29:40 AM EDT.

My apologies for the inconvenience: the system for processing emailed responses was not processing all of them correctly (and it was only reported to us recently, so we didn't realize it). This has been fixed, but may result in older messages (from the last two weeks) showing up on May 8 and May 9 in your message thread. We have also taken steps to monitor this system more closely so we will know immediately in the future if there is a problem. Again, my apologies and thanks for your understanding.

The Sunk Cost Fallacy in Reverse Auctions
By Yu Wu, Stanford University, California; Hang Ung, Ecole Polytechnique Palaiseau, France; Christina Aperjis, Hewlett-Packard Laboratories, California.

If you want to win a project, everyone knows you should bid as quickly and early as possible to best capture the employers attention...right? Wrong! This study found out that early bids do not have an advantage, and employers actually tend to pick the very last bid more than any other bid placed! This fascinating paper attempts to explain this counter-intuitive finding using a model of employer behavior called the "Sunk Cost Fallacy", and is useful for both workers looking to improve the number of bids they win, and employer wanting to understand their own behavior better.

By David Gefen (Drexel University) and Erran Carmel (American University)
In MIS Quarterly 2008, pages 367-384

According to the "flat world" model, employers should always choose the lowest-cost offshore bidder over a higher-cost domestic bidder. However, this study of years of vWorker data shows that this is not the case.
