Electronic exchanges are double-sided marketplaces
that allow multiple buyers to trade with multiple sellers,
with aggregation of demand and supply across the bids to
maximize the revenue in the market. Two important issues
in the design of exchanges are (1) trade determination (determining
the number of goods traded between any buyer-seller
pair) and (2) pricing. In this paper we address the
trade determination issue for one-shot, multi-attribute exchanges
that trade multiple units of the same good. The
bids are configurable with separable additive price functions
over the attributes and each function is continuous and
piecewise linear. We model trade determination as mixed
integer programming problems for different possible bid
structures and show that even in two-attribute exchanges,
trade determination is NP-hard for certain bid structures.
We also make some observations on the pricing issues that
are closely related to the mixed integer formulations.
