Abstract

This study identi es a set of interim self-stable decision rules. In our model, individual voters encounter two separate decisions sequentially: (1) a decision on the change of a voting rule they are going to use later and (2) a decision on the nal voting outcome under the voting rule which has been decided from the prior procedure. A given decision rule is self-stable if any other possible rule does not get enough votes to replace the given rule under the given rule itself. We fully characterize the set of interim self-stable decision rules among weighted majority rules with given weights.
