Olivier Armantier et Nicolas Treich, « Star-Shaped Probability Weighting Functions and Overbidding in First-Price Auctions », TSE Working Paper, n°09-024, mars 2009.
[ Texte complet ]


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.
