Preference Representation for Multi-Unit Multiattribute Auctions

Yagil Engel, Kevin M. Lochner, Michael P. Wellman

The problem of multi-unit multiattribute trading, though useful in practical procurement settings, has been rarely addressed in auction literature. We present a general framework to structure specifications of preferences over multi-unit multiattribute outcomes, allowing flexible tradeoffs between expressiveness and compactness of representation. Next, we use this framework to propose an auction mechanism with useful economic and computational properties, applicable over a substantial part of the general preference domain.
