We present results from a series of experiments that allow us to measure overbidding and, in particular, underbidding in first-price auctions. We investigate how the amount of underbidding depends on seemingly innocent parameters of the experimental setup. To structure our data we present and...

We conduct an experiment to uncover the reasons behind the typically large behavioral variation and low explanatory power of Nash equilibrium observed in Tullock contests. In our standard contest treatment, only 7% of choices are consistent with Nash equilibrium which is in line with the...

The Winner s Curse (WC) is a non-equilibrium behavior in common-value auctions involving systematic and persistent overbidding that often results in significant losses. It is one of the most robust findings in laboratory experiments. We developed an auction mechanism with a payment rule that...
