This paper analyses the evaluation of the relative performance of a set of groups when their outcomes are defined in terms of categorical data and the groups’ members are heterogeneous. This type of problem has been dealt with in Herrero and Villar (2012) for the case of a homogenous...

This paper provides a criterion to evaluate the overall performance of a given number of groups whose members can be of different types, out of the analysis of their relative frequencies. Assuming that types can be ordered from best to worse, the starting point is that of dominance relations in...

The purpose of this paper is to offer a characterization of a welfare index which depends positively on total income and negatively on Theil's first inequality measure. This welfare index belongs to a family of indicators which try to link measures of income and measures of welfare (real-income...

This paper deals with the analysis of the existence and optimality allocations in a framework characterized by the presence of consumption externalities. The model refers to apure distribution problem consisting of allocating a given bundle of k goods among n agents. Analizamos en este trabajo...

This paper analyzes the existence of efficient equilibrium allocations in an economy with many convex and non-convex firms. A Social Equilibrium is defined as a price vector and an allocation satisfying the following properties: a) Consumers satisfy their preferences, subject to their budget...

The purpose of this paper is to offer an exposition of the results on the existence and optimality of equilibria when production sets are not assumed to be convex, in a general equilibrium framework. We aim at providing a formal and systematic account of the main results available, rather than...

Este trabajo presenta una integración del enfoque normativo de Dalton- Atkinson-Sen sobre la medición de la desigualdad con el enfoque positivo vinculado a las medidas estadísticas de dispersión o la familia de índices de entropía generalizados. Nuestra aportación elige un índice de...

This paper deals with the analysis of allocation problems with single peaked preferences, under the condition of agenda-independence (that is, when the allocation rule yields the same final outcome, no matter how the problem is subdivided into partial problems). Since the Uniform rule does not...

The problem of distributing a given amount of a divisible good among a set of agents which may have individual entitlements is considered here. A solution to this problem, called the Rights-Egalitarian Solution, is proposed and characterized. This allocation rule divides equally among the agents...
