We study three alternative versions of the Vickrey (1961) auction when bidders have multi-unit demands: Vickrey’s original static sealed-bid auction and two dynamic implementations of the same auction: with and without dropout information reported during the auction (Ausubel, 1997). Although implemented by a weaker a weaker solution concept, behavior in the dynamic Vickrey auction with dropout ...

The 2010 German 4G spectrum auction was an unusually large simultaneous ascending multi-band auction. The bidding was competitive and the final assignment was efficient. However, our analysis suggests that independent and rational bidders had an opportunity to coordinate implicitly on a lowrevenue outcome. Coordination was difficult, though, because of a multiplicity of focal points. One import...

With the continuous development of social software and multimedia technology, images have become a kind important carrier for spreading information socializing. How to evaluate an image comprehensively has focus recent researches. The traditional aesthetic assessment methods often adopt single numerical overall scores, which certain subjectivity can no longer meet higher requirements. In this a...

Optimal Multi-parameter Auction Design

Petro physics, rock physics and multi-attribute analysis have been employed in an integrated approach to delineate porosity variation across Tamag Field of Niger Delta Basin. Gamma and resistivity logs were employed to identify sand bodies and correlated across the field. Petro physical analysis was undertaken. Rock physics modelling and multi-attribute analysis were carried out. Two hydrocarbo...

This paper considers a multi-unit ascending auction with two players and common values. A large set of equilibria in this model is not robust to a small reputational perturbation. In particular, if there is a positive probability that there is a type who always demands many units, regardless of price, then the model has a unique equilibrium payo¤ pro…le. If this uncertainty is only on one side,...

This work deals with the development of a dynamic task assignment strategy for heterogeneous multi‐robot teams in typical real world scenarios. The strategy must be efficiently scalable to support problems of increasing complexity with minimum designer intervention. To this end, we have selected a very simple auction‐based strategy, which has been implemented and analyse...

This chapter addresses the complex scenario of multi cell OFDMA network resource allocation and interference control by auction theory. An auction framework that meets the properties of efficiency and incentive compatibility is proposed. We consider a multi-cell OFDMA network with Fractional Frequency Reuse (FFR) implementation. An auction is presented to allocate subcarriers. According to the ...

insurance companies are important economic institutions in each country and support other economic institutions and good performance of them has an effective role in economic boom. insurance companies to achieve strong and effective performance must be aware of the environment, the competitor and their performance and carry out necessary actions with regard to this information. in this study, t...

This work investigates allocation of tasks to multi-robots when tasks are spatially distributed and constrained to be executed within assigned time windows. Our work explores the interaction between scheduling and optimal routing. We propose the Time-Sensitive Sequential Single-Item Auction algorithm as a method to allocate tasks with time windows in multi-robot systems. We show, experimentally...
