This paper refers to some social evaluation problems when equity matters. We propose here a way of assessing the equality of opportunity that is applicable to categorical data. It consists of dividing society into groups with similar characteristics and to measure the dispersion of outcomes...

This paper refers to the ranking of densities that describe the distribution of an attribute in a given set of populations. The key elements of the problem are: (i) The distributions refer to ordered categorical data (e.g. health statuses, educational achievements, prestige positions,...

This paper analyzes 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 (2013) for the case of a homogeneous...

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...

This paper deals with the existence of equilibrium in an economic model in which production is modeled i n terms of a nonlinear Leontief system, firms sell their outputs at t he average cost, and consumers choose their demand according to the s upply prices. Copyright 1988 by Blackwell...

The purpose of this paper is to extend the Rights Egalitarian solution (Herrero, Maschler & Villar, 1999) to the context of non-transferable utility sharing problems. Such an extension is not unique. Depending on the kind of properties we want to preserve we obtain two different generalizations....

This paper reports the results of an experiment in which probabilistic insurance, as proposed by Kahneman and Tversky (1979), is compared both with full insurance and no insurance. The experimental results conform to the intuitive prediction that risk-averse agents who are indifferent between...
