In this paper we consider equilibrium behavior in a Dutch (descending price) auction where the bidders are uninformed of their valuations with probability 1-q and can acquire information about their valuation at a positive cost during the auction. We assume that the information acquisition...

This paper studies multi-attribute auctions in which a buyer seeks to procure a complex good and evaluate offers using a quasi-linear scoring rule. Suppliers have private information about their costs, which is summarized by a multi-dimensional type. The scoring rule reduces the multidimensional...

This paper considers a general package auction problem and a class of payment rules we refer to as standard. In a “standard” pricing rule, each winner pays at least his “minimum required value” to win. The minimum required value coincides with the payment in the Vickrey auction, and...

In this paper we consider equilibrium behavior in a Dutch (descending price) auction where the bidders are uninformed of their valuations with probability q and can acquire information about their valuation at a positive cost during the auction. We assume that the information acquisition...

We propose a novel approach to the modelling of second-price Maximum-Value auctions that assumes no belief about others' behavior and no expected profit maximization. This individual decision-making model, naïve Impulse Balance Equilibrium or nIBE, deals with bidders' anticipated regrets from...

Affiliation has been a prominent assumption in the study of economic models with statistical dependence. Despite its large number of applications, especially in auction theory, affiliation has limitations that are important to be aware of. This paper shows that affiliation is a restrictive...
