An axiomatic analysis of ranking sets under simple categorization
This paper contributes to the axiomatization of additive rules for ranking sets of objects under the psychological principle of categorization. Firstly we proceed with the case where the elements in the sets are categorized ... 
Equality of opportunities: cardinalitybased criteria
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 ... 
Fair competition design
We study the impact of two basic principles of fairness on the structure of competition systems and perform our analysis by focusing on sports competitions. The first principle states that equally strong players should ... 
Fair eliminationtype competitions
(Elsevier, 2020) Artículo / ArtikuluaWe study the impact of two basic principles of fairness on the structure of eliminationtype competitions and perform our analysis by focusing on sports competitions. The first principle states that stronger players should ... 
Freedom of choice and conflict resolution
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 ... 
Freedom of choice: the leximax criterion in economic environments
Many recent works have investigated the question of extending a preference over a set of alternatives to its power set, as a way to provide a formal representation of the notion of freedom of choice. In general, the results ... 
Freedom of choice: the leximax criterion in the infinite case
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 ... 
Incomplete preferences and the preference for flexibility
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 ... 
Manipulative agendas in fourcandidate elections
(Elsevier, 2020) Artículo / ArtikuluaWe consider a setting where it is known for an electorate what probability a given candidate has of beating another in a pairwise ballot. An agenda assigns candidates to the leaves of a binary tree and is called manipulative ... 
Note on Bossert, Pattanaik and Xu’s “Choice under complete uncertainty: axiomatic characterization of some decision rules”
Recent work by Bossert, Pattanaik and Xu provides axiomatic characterizations of some decision rules for individual decision making under complete uncertainty. This note shows that, in the case of two of these rules, they ... 
On freedom of choice, ambiguity, and the preference for easy choices
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 ... 
On procedural freedom of choice
Numerous works in the last decade have analyzed the question of how to compare opportunity sets as a way to measure and evaluate individual freedom of choice. This paper defends that, in many contexts, external procedural ... 
On the aversion to incomplete preferences
We propose an axiomatization of aversion to incomplete preferences. Some prevailing models of incomplete preferences rely on the hypothesis that incompleteness is temporary and that by keeping their opportunity set open ... 
On the equivalence of the two existing extensions of the leximax criterion to the infinite case
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 ... 
Participation in and provision of public goods: Does granularity matter?
We use public goods games to experimentally investigate the effect of granularity (i.e., the degree of divisibility of the space of feasible contribution options) on participation (whether individuals contribute or not to ... 
Power set extensions of dichotomous preferences
This paper is devoted to the study of how to extend a dichotomous partition of a universal set X into good and bad objects to an ordering on the power set of X. We introduce a family of rules that naturally take into ... 
Ranking sets additively in decisional contexts: an axiomatic characterization
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 ... 
Rational evaluation of actions under complete uncertainty
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. ... 
A theory of choice under internal conflict
In this paper we discuss, inspired by some psychological literature, that choices are the outcome of the interplay of different, potentially conflicting motivations. We propose an axiomatic approach with two motivations, ... 
Uncertainty with ordinal likelihood information
We present a model that is closely related to the socalled models of choice under complete uncertainty, in which the agent has no information about the probability of the outcomes. There are two approaches within the said ...
