I am a Ph.D. student in LAMSADE (CNRS UMR 7243) at Université Paris-Dauphine since October 2018. The title of my proposal is “Elicitation and Explanation for Voting Rules” and its goal is the development of procedures able to help a committee (or a society) choose a suitable voting rule.
Voting rules are formal means to aggregate preferences of a group of voters into a collective decision. But which rule to use is a difficult question and it depends on the conception of justice of the concerned society or committee. No rule can be considered the best independent of the context. A voting rule can be characterized by a set of axioms, and the axiomatic analysis is a well-accepted approach to studying the properties satisfied by voting rules. But the choice of which axioms should be satisfied should not be left to scientists. So, methods to present axioms and their consequences to non-expert users must be implemented. Moreover we cannot simply ask the committee which axioms it likes, because it is often impossible for non-experts users to see the consequences of accepting a set of axioms. So elicitation techniques exist that can capture informal subjective preferences into formal models.
