text: "We characterise the set of dominant strategy incentive compatible (DSIC),
strongly budget balanced (SBB), and ex-post individually rational (IR) mechanisms
for the multi-unit bilateral trade setting. In such a setting there is a single
buyer and a single seller who holds a finite number k of identical items. The
mechanism has to decide how many units of the item are transferred from the seller
to the buyer and how much money is transferred from the buyer to the seller. We
consider two classes of valuation functions for the buyer and seller: Valuations
that are increasing in the number of units in possession, and the more specific
class of valuations that are increasing and submodular. \r\nFurthermore, we present
some approximation results about the performance of certain such mechanisms, in
terms of social welfare: For increasing submodular valuation functions, we show
the existence of a deterministic 2-approximation mechanism and a randomised e/(1-e)
approximation mechanism, matching the best known bounds for the single-item setting."
