This paper proposes a new framework of choice under uncertainty, where the only information available to the decision maker is about the the ordinal likelihood of the different outcomes each action generates. This contrasts ...

Sometimes individual agents display in their decisions a preference for having more opportunities to choose from. In this paper this fact is interpreted from a preference for flexibility approach, which links with the ...

In this paper we study possible rankings of opportunity profiles. An opportunity profile is a list of sets of alternative opportunities, one set for each agent in the society. We compare such opportunity profiles on the ...

Ranking finite subsets of a given set X of elements is the formal object of analysis in this paper. This problem has found a wide range of economic interpretations in the literature. The focus of the paper is on the family ...

This paper is devoted to the study of opportunity set comparisons when the characteristics of the options within the sets in question may be ambiguous. We assume that agents display a preference for freedom of choice, but ...

Many recent works have investigated the problem of extending a preference over a set of alternatives to its power set, in an attempt to provide a formal representation of the notion of freedom of choice. In general, results ...

Using a common framework, we consider the two existing extensions of the leximax criterion to infinite environments (Arlegi et al. (2005) and Ballester and De Miguel (2003), and show that, though the respective definitions ...

This work is an output of my participation in the project 'Procedural Approaches to Conflict Resolution', coordinated by Professor Matthias Raith. The main goal of the project was making an interdisciplinary approach to ...

This work analyzes the problem of individual choice of actions under complete uncertainty. In this context, each action consists of a set of different possible outcomes with no probability distribution associated with them. ...

This paper explores the introduction of a variable critical-level in a variable population context. We focus the attention on the “Critical-Level Egalitarian Rule”, a social evaluation procedure which compares two social ...
