The behavior is overbidding, bidding higher than the known value of an abstract asset, in sealed-bid auctions conducted under second- price rules. This fundamentally violates both fully rational and boundedly rational models of behavior, since the observed overbidding is a failure to adopt a dominant strategy.
How do you win a second price auction?
