In this paper, we study values for TU-games which satisfy three classical properties: Linearity, efficiency and symmetry. We give the general analytical form of these values and their relation with the Shapley value and the Egalitarian value.

The aim of this paper is to propose a new class of inequality indices. It is a generalisation of Gini coefficient based on his interpersonal expression. We inter into axiomatic properties of our indices and we show that they are relative, regular indices which, in particular, satisfy the...

The working population is becoming more and more feminized from 2000 to 2008 in Cameroon. Women receive on average a salary lower than that of the men and the sex remains a significant determiner of the professional position in Cameroon. From Oaxaca-Blinder(1973)decomposition, this work suggests...

This study evaluates the effectiveness of the mechanisms of stabilization of shocks in heterogeneous monetary zone, with an application on the Franc Franc zone. The study assesses the advantages and disadvantages of budget cooperation strategies against non-cooperation. It shows that fiscal...

This paper proposes a new class of inequality indices based on the Gini’s coefficient. The properties of the indices are studied and in particular they are found to be regular, relative and satisfy the Pigou-Dalton transfer principle. A subgroup decomposition is performed and the method is...

Two well-known single valued solutions for TU-games are the Shapley value and Solidarity value, which verify three properties: Linearity, Symmetry and Efficiency, and the null player axiom. On the other hand, the interpretation of the two values is usually related on the marginal contribution of...

This paper proposes new factors decomposition methods for classical inequality indices such as Gini index, variance and squared coefficient of variations index. The approach consists in relaxing the normalization property in order to extend the natural decomposition to a decomposition rule which...

The paper studies the ordinal equivalence of Linear, Efficient and Symmetry (LES) values in TU-games. It demonstrates that most of the results obtained by Carreras F, Freixas J (2008) in the case of semivalues and simple games are transposable on LES values and the whole TU-games set. In...
