Simulation using agents has gained a wide prominence in a wide area of applications. In particular agent-based negotiation is concerned with simulating the behavior of parties interacting with each other to reach an agreement. In this paper, a construction-specific model for negotiation between agents representing contractors in a Reverse Auction Bid (RAB) is presented. RAB is a fairly new elec...

A result of Bulow and Klemperer has suggested that auctions may be a better tool to obtain an efficient outcome than negotiation. For example, some auction mechanisms can be shown to be efficient and strategy-proof. However, they generally also require that the preferences of at least one side of the auction are publicly known. However, sometimes it is very costly, impossible, or undesirable to...

Some auction mechanisms can be shown to be efficient and strategy-proof. However, they generally require that the preferences of at least one side of the auction are publicly known. However, sometimes it is very costly, impossible, or undesirable to publicly announce such preferences. It thus is interesting to find methods that do not impose this constraint but still approximate the outcome of ...

However, one of the most severe and persistent problems in such systems is shilling behavior, which is a type of auction fraud where a bidder artificially drives up the bidding price so that the winner of the auction has to pay more than he otherwise would pay. Verification of shill bidders in an online auction is difficult d...
