A diagonal image may be defined as a point in the image of agiven mapping, whose components are all equal. This paper investigates sufficient conditions for a set-valued mapping to have quasi-diagonal images(in an extended sense). More specifically, we shall show that anupper-hemicontinuous...

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...

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...

In this paper a numerical representation of preferences by means of subsets of the real line is proposed. This representation turns out to be natural for partial orderings. Some results on this representation, extending those for utility functions and pairwise representations, are provided for...

The purpose of this paper is to provide a new solution concept for bargaining problems, which modifies Chun's Equal-Loss Solution in a way that ensures the individual rationality. We also consider its lexicographic extension which turns out to be both individually rational and Pareto Optimal....

Some shortcomings of the equal-loss solution for bargaining problems are noticed: in general, it is not individually rational, and in case it is, then turns out a selection of the YU solutions. Finally, a new way of proving characterization results is provided.

A modifica.tion of the proportional solution for bargaining with claims problems is proposed. This solution is construct.ed by considering an endogenous reference point. Characterization results are provided when the feasible set is not necessarily convex.

Starting from a finite or countable set of states of health, and assuming the existence of an objective transitive preference relation on that set, we propose a way of performing interpersonal comparisons of states of health. In so doing, we first consider the population divided into types, and...

This paper focuses on two new properties for bankruptcy rules: preeminence and sustainability. Theypertain to situations when the claims of some agents are much larger than the claims of otheragents. They differ in the way the recommend agents with small claims to be treated. Preeminencerequires...
