In a distribution problem, and specifically in bankruptcy issues, the Proportional (P) and theEgalitarian (EA) divisions are two of the most popular ways to resolve the conflict. TheConstrained Equal Awards rule (CEA) is introduced in bankruptcy literature to ensure that noagent receives more...

Evidence of the existence of overeducation in the Spanish labour market has drawn the attention of research on the transitory character of overeducation (Alba-Ramirez, 1993 and García and Malo, 1995). Our main interest lies on whether overeducation is a source of inefficiency in the allocation...

In this paper we analyze the explicit representation of fixed agenda social choice correspondence under different rationality assumptions (independence, neutrality, monotonicity, ...). It is well know in the literature that, under some of theses assumptions, the existence of dictators,...

A weaker than usual continuity condition for acyclic preferences is introduced. For preorders this condition turns out to be equivalent to lower continuity, but in general this is not true. By using this condition, a numerical representation which is upper semicontinuous is obtained. This fact...

Tournaments are complete and asymmetric binary relations. This type of binary relation rules out the possibility of ties or indifferences which are common in different contexts. In this work we generalize, from a normative point of view, some important tournaments solutions (top cycle, uncovered...

The existence of maximal elements for binary preference relations is analyzed without imposing transitivity or convexity conditions. From each preference relation a new acyclic relation is defined in such a way that some maximal elements of this new relation characterize maximal elements of the...

Numerical representations of choice functions allow the expression of a problem of choice as a problem of finding maxima of real valued functions, which requires less information to be defined and which is easier to work with. In this paper, the existence of numerical representations of choice...

In a choice situation, it is usually assumed that the agents select the maximal elements inaccordance with their preference relation. Nevertheless, there are situations in which a selectioninside this maximal set is needed. In such a situation we can select randomly some of thesemaximal...

How should scholarships be distributed among the (public) higher education students? We raise thissituation as a redistribution problem. Following the approach developed in Fleurbaey (1994) andBossert (1995), redistribution should be based on the notion of solidarity and it re-allocates...

The analysis of the determinants of the individual wage income can be transfered to the total domestic income from the point of view of the human capital. This paper analyzes the effects that a group of variables, relative to sociodemographic and labour attributes, exerts on the total income...
