On the expressiveness of assignment messages

Author

  • Fichtl, Maximilian

Abstract

In this note we prove that the class of valuation functions representable via integer assignment messages is a proper subset of strong substitutes valuations. Thus, there are strong substitutes valuations not expressible via assignment messages.
