This paper presents two new axiomatizations of the Owen value for games with coalition structures. Two associated games are defined and a consistency axiom is required. The construction of the associated games presupposes that coalitions behave in an aggressive manner towards players who are not...

The aim of this paper is to present a new value of a cooperative game for the case of limited communication between players. The communication system we consider may be represented by a simple graph, that is, only pairwise meetings can occur and some of them are not permitted. An associated game...

We present a new extension of the Shapley value for games with communication structure,only pairwise meetings can occur when some of them are not permitted.The present extension is a new one and in particular it is di .erent from the Myerson value,from the position value,and from a previous...

In this work, a new axiomatization of the Shapley value is presented. An associated game is constructed which can also be interpreted as a perturbation of the original game. We define a sequence of games, when the term of order n, in this sequence, is the associated game of the term of order (n-1).

The aim of this paper is to present an approach to the middleman problem in the context of cooperative games when communication between players is graph-restricted. We consider a set of three axioms: linearity, dummy player and independence of non connected coalitions. These axioms are generally...

This paper presents two new axiomatizations of the Owen value for games with coalition structures. Other axiomatizations can be found in the literature: Owen (1977), Hart and Kurz (1983), and Winter (1992). The driving force of my axiomatization is a consistency axiom based on an associated...

We study social choice functions for societies confronting alternatives which can be described as vectors in a Euclidean space, and where all voters have preferences on these alternatives which are saturated at an ideal point and satisfy an appropriate restriction of single-peakedness.

This paper studies the consequences of a private or depletable externality on free trade agreements in a general equiilibrium framework. It is shown that there always exists a stable system of free trade spaces in the world economy. This stable system can result in either non-cooperation,...

We address the issue of optimal growth when standard-of-living aspirations are transmitted from one generation to the next. We derive the condition for the optimal solution to be stable in the saddle-point sense and show that this optimal solutionmay display damped oscillations even when the...

This paper analyzes the problem of altering the cost structure within an oligopoly, in the presence of costs of manipulation. Oligopolistic firms (which differ from each other in production costs) compete a la Cournot in the second stage, taking as given firm-specific taxes or input prices. In...
