# Optimal Auctions with Ambiguity

@inproceedings{Bose2004OptimalAW, title={Optimal Auctions with Ambiguity}, author={Subir Bose and Emre Ozdenoren and Andreas Duus Pape}, year={2004} }

A crucial assumption in the optimal auction literature has been that each bidder's valuation is known to be drawn from a single unique distribution. In this paper we relax this assumption and study the optimal auction problem when there is ambiguity about the distribution from which these valuations are drawn and where the seller or the bidder may display ambiguity aversion. We model ambiguity aversion using the maxmin expected utility model where an agent evaluates an action on the basis of…

### Auction Design with Ambiguity: Optimality of the First-Price and All-Pay Auctions

- EconomicsSSRN Electronic Journal

We study the optimal auction design problem when bidders' preferences follow the maxmin expected utility model. We suppose that the bidders' set of priors consists of beliefs "close" to the seller's…

This work defines the auction design problem as a zero-sum game between the seller, who chooses a mechanism, and a fictitious adversary or 'nature,' who chooses the bidders' values from within the uncertainty set with the aim to maximize the seller's regret.

This thesis consists of three chapters which analyze mechanisms and strategies in auctions which are robust with respect to uncertainty about the given economic setting and a new decision criterion is proposed which allows the agent to derive strategies given strategic uncertainty.
