Lifting preferences over candidates to preferences over sets of candidates allows us to give a very natural notion of manipulability for social choice functions. In particular, we give simple conditions over the liftings entailing the manipulability of reasonable social choice functions. Our result is a weak version of Barberà and Kelly's Theorem, indeed it can be obtained from this last Theorem. However, we give a direct and very natural proof of our manipulability Theorem which is informative about the nature of the liftings allowing manipulability.
Transferir preferencias sobre candidatos a preferencias sobre conjuntos de candidatos permite dar una noción muy natural de manipulación para funciones de elección social. En este trabajo damos condiciones sobre esas funciones de transferencia que implican la manipulabilidad de funciones de elección social con un mínimo de propiedades razonables. Nuestro resultado es una versión débil del teorema de Barberà y Kelly, de hecho puede ser obtenido como una consecuencia de éste. Sin embargo, damos una prueba directa y natural de nuestro teorema de manipulabilidad, la cual da una información clara sobre la naturaleza de las funciones de transferencia que permiten la manipulación.
