Cloning-proof social choice correspondences

Abstract

In this thesis study, we provide axiomatic characterizations of the well-known Condorcet and Plurality rules via consistency axioms when the alternative set is endogeneous, namely hereditariness and cloning-proofness. Cloningproofness is the requirement that the social choice rule be insensitive to the replication of alternatives, whereas hereditariness requires insensitivity to withdrawal of alternatives.
