We consider marketplaces where buyers and sellers iteratively encounter to trade. Given some speciﬁc trade conditions, the question that we address is what strategies should buyers and sellers use to maximize gains. We focus on electronic markets where supply shortages are common. Under such market conditions sellers can only satisfy a subset of the purchase-orders they receive from buyers. Consequently, some buyers may become discontented and they may be motivated to migrate to other sellers in proceeding encounters. Beneﬁcial purchase-order selection as well as seller selection require, respectively, seller and buyer strategies. Analytical computation of stable proﬁles of such strategies is infeasible in the enviroments we examine. We hence devise a new methodology for studying strategic equilibria. We introduce speciﬁc equilibria strategy proﬁles to be implemented by automated trade agents. The main conclusions of our study are that automated sellers will beneﬁt most by...
