Preferencias, Elección Social y Ayuda a la Decisión

(PRESAD)


Objetivos: Este grupo de investigación aborda varios temas colindantes que tienen en común la agregación de información, tanto en la toma de decisiones colectivas como en la generación de índices sintéticos. Los principales objetivos del grupo son el diseño y análisis de: - Sistemas de votación. - Medidas de desigualdad, bienestar y pobreza. - Medidas de consenso. - Formación de grupos y conglomerados.
Líneas de investigación: Ayuda a la decisión. Modelización de preferencias. Elección social.
