We use the approach of the reduced Game Property and its converse to characterize the sets of stable and semistable demand vectors. It is shown that although these two concepts are generally very different their axiomatizations are almost the same. Regarding the semistable demand vector we...

In the present paper we discuss the notion of values for games with coalition structure, applying the approach suggested by Hart and Mas-Colell (1985) concerning the consistency property and the potential function. An axiomatic formulation of the values by this approach leads to two known values...
