La Moderna teoria de l'elecció social: de la impossibilitat a la possibilitat

Authors

  • Jordi Massó Carreras

Abstract

We present the two most important impossibility theorems of the modern social choice theory: Arrows theorem for social welfare functions satisfying the Pareto principle and the independence of irrelevant alternatives property, and Gibbard-Satterthwaites theorem for non-trivial and strategy-proof social choice functions. We describe seven examples of specific social choice problems where the particular structure of the set of social alternatives allows to restrict the domain of individual preferences and to design for each of them strategy-proof social choice functions on the corresponding restricted preference domains.
