The aim of this paper is to determine the representation of parties in a Parliament that guarantees an equal representation of all the citizens. This problem is illustrated in the Israeli Knesset.

In this paper we explore the noncooperative foundations of the bargaining power that a voting rule gives to each member of a committee that bargains in search of consensus over a set of feasible agreements under a voting rule. Assuming complete information, we model a variety of bargaining...
