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.N. Kakimura and D. Zhu. Dynamic bipartite matching market with arrivals and departures.
