  Production-inventory games were introduced in Guardiola et al. (2007) as a
new class of totally balanced combinatorial optimization games. From among all
core-allocations, the Owen point was proposed as a specifically appealing
solution. In this paper we study some relationships of the class of
production-inventory games and other classes of new and known games. In
addition, we propose three axiomatic characterizations of the Owen point. We
use eight axioms for these characterizations, among those, inessentiality and
additivity of players' demands are used for the first time in this paper.
