We present a simple voting environment with three candidates where the Condorcet winner exists. Under plurality rule, the derived game has a stable set where such a candidate is elected with probability one. However, no stable set of the approval game elects the Condorcet winner with positive...

We prove that for generic plurality games with positive cost of voting, the number of Nash equilibria is finite. Furthermore all the equilibria are regular, hence stable sets as singletons. Copyright Springer-Verlag Berlin/Heidelberg 2005

Il saggio propone alcune riflessioni sulle culture politiche, giuridiche e sociologiche vicine al pensiero delle numerose e ostinate ricerche militanti di Bruno Trentin. Non si tratta di "saggiare" l’indiscutibile attualità dell’imponente corpus teorico trentiniano, quanto di partire dalle...

In this paper we propose a model in which there are ideological and strate- gic voters who vote under poportional rule. We prove that the behavior of ideological voters matters for the determination of the outcome. We show that a subset of strategic voters partially counteracts the votes of the...

We consider a model where policy motivated citizens vote in two simultaneous elections, one for the President who is elected by majority rule, in a single national district, and one for the Congressmen, each of whom is elected by majority rule in a local district. The policy to be implemented...

In this paper we propose a model in which there are ideological and strategic voters who vote under proportional rule. We prove that the behavior of ideological voters matters for the determination of the outcome. We show that a subset of strategic voters partially counteracts the votes of the...
