We develop a model of endogenous party platform formation in a multidimensional policy space. Party platforms depend on the composition of the parties? primary electorate. The overall social outcome is taken to be a weighted average of party platforms and individuals vote strategically....

A one-dimensional model of spatial political competition with endogenous party formation is developed. It is proved that at equilibrium there are only two parties. These parties propose alternatives in the extreme position s of the policy space. The adopted policy, however, is a compromise...

In modern elections, ideologically motivated candidates with a wealth of information about individual voters and sophisticated campaign strategies are faced by voters who lack awareness of some political issues and are uncertain about the exact political positions of candidates. We study to what...

We consider voting rules on a multidimensional policy space for a continuum of voters with elliptic preferences. Assuming continuity, gamma -strategy-proofnessmeaning that coalitions of size smaller or equal to a small number gamma cannot manipulateand unanimity, we show that such rules are...
