Olivier Armantier, and Nicolas Treich, “Star-Shaped Probability Weighting Functions and Overbidding in First-Price Auctions”, TSE Working Paper, n. 09-024, March 2009.
There is a debate about whether risk aversion is the main source of overbidding in a first-price independent private values auction. As an alternative, we adopt a non-expected utility framework, and identify an interpretable property on the probability weighting function which always induces overbidding.
