ABSTRACT: In the one-sided assignment game any two agents can form a partnership. If this is done, the partners undertake some join activity, which produces a gain that is spitted between them. We approach this model by focusing on simple outcomes (feasible and individually rational outcomes where only unmatched agents can block). We prove that this blocking can be done in such a way that the payoffs from the trades done are not changed as players reach the core. In addition, the total sum of these payoffs is the same at any core outcome. The gains in insight with this approach allow a necessary and sufficient condition for the non-emptiness of the core to be identified. Several properties of the core outcomes of economic interest are proved.
