Abstract

Approval voting features are analysed in a context of large elections with strategic voters: Myerson's Large Poisson Games. I first establish the Magnitude Equiva- lence Theorem (MET) which substantially reduces the complexity of computing the magnitudes of pivotal events. I also show that the Winner of the election coincides with the Profile Condorcet Winner at equilibrium when preferences are restricted to be single-peaked. This is a positive result that strengthens the positive conclusions some scholars have previously drawn over this voting rule. I finally show that, with- out the previous restriction over preferences, both concepts do not generally coincide anymore.
