Multi-Item Vickery-English-Dutch Auctions

Assuming that bidders wish to acquire at most one item, this paper defines a polynomial time multiitem auction that locates the VCG prices in a finite number of iterations for any given starting prices. This auction is called the Vickrey-English-Dutch auction and it contains the Vickrey-English auction (J.K. Sankaran, Math. Soc. Sci. 28:143–150, 1994) and the Vickrey-Dutch auction (D. Mishra and D. Parkes, Games Econ. Behav. 66:326–347, 2009) as special cases. Several properties of this iterative auction are provided. It is, for example, demonstrated that the number of iterations from the star... Mehr ...
