In this paper, we consider political competition games of two parties in multi-dimensional policy spaces, where the two parties have two factions, opportunists and militants, that intra-party bargain with each other. In such a game, we adopt the party-unanimity Nash equilibrium (PUNE) [Roemer (1998;...

An extended social choice framework is proposed for the analysis of initial conferment of individual rights. This framework captures the intuitive conception of decision-making procedure as a carrier of intrinsic value along with the instrumental usefulness thereof in realizing valuable...

This paper discusses and develops "non-welfare" arguments on distributive justice a la J.Rawls and A.K. Sen, and formalizes, in co-operative production economies, "non-welfaristic" distribution rules as game form types of resource allocation schemes. First, it conceptualizes the Needs Principle...

In pruoduction economies with skill differences, this paper discusses resource allocation schemes which are consistent with two notions of procedural fairness: labor sovereignty and equal-division-for-equal-work (EDEW)[Kranich(1994)]. The paper first shows that there always exists an efficient...

In production economies with unequal skills, this paper characterizes bargaining solutions by using axioms on allocation rules rather than axioms on classical bargaining solutions. Instead of Consistency of Resource Allocation across Dimension (CONRAD)[Roemer (1986, 1988)], which is essentially...

We reconsider the three well-known solutions: the Nash, the egalitarian and the Kalai-Smorodinsky solutions, to the classical domains of convex bargaining problems. A new proof for the Nash solution that highlights the crucial role the axiom Contraction Independence plays is provided. We also...

In this paper, we consider production economies with possibly unequal production skills and with possibility of technological innovations, in which resource allocations are determined via bargaining among individuals. We define the Nash bargaining solution as the (bargaining) allocation rule...
