At the end of the 1990s online reverse auctions were proposed as a powerful tool to improve the performance of corporate procurement. However, as many of the promises of the e-Business world failed to materialize the issue received only little attention during the last years. Hence, it is not known what kind of role reverse auctions play and what kind of auction designs are used in practice. Fo...

In this paper we study the Nash-equilibrium and equilibrium bidding strategies of the Pooled Reverse Auction for troubled assets. The auction was described in (Ausubel & Cramton 2008[1]). We further extend our analysis to a more general class of games which we call Summation Games. We prove the existence and uniqueness of a Nashequilibrium in these games when the utility functions satisfy a cer...

Participation of people is the most important factor in providing high quality of service in participatory sensing applications. In this paper we study monetary incentives in order to stimulate user’s participation, especially in applications that rely on real-time data. Providing such incentives is hard because the service provider cannot determine the price at which each user would be willing...

I examine bid behavior in uniform-price auctions and multi-unit Vickrey auctions, without the standard quasilinearity restriction on bidder preferences. Instead of assuming quasilinearity, I assume that bidders have weakly positive wealth effects, i.e. the goods are normal goods. My setting nests quasilinearity, but also allows for budget constraints, financial constraints, and risk aversion. I...

In this paper, we present an agent which is able to negotiate the buying and selling of imperfectly sustitutable goods in a double auction style market. Two goods are said to be imperfectly substitutable if a buyer can use either of them, but prefers one over the other. For example, an electronics manufacturer using a RAM chip can use many suppliers to do this but may be willing to pay a premiu...

In this paper we consider a procurement multi-attribute English auction with a deadline. This protocol can be used for agents who try to reach an agreement on an item or issue, which is characterized by several quality attributes in addition to the price. The protocol allows the specification of a deadline since in many real world situations it is essential to conclude a negotiation among agent...
