Document Summary

Electoral system you have incentivices different structures of party systems. If you have a pure proportional system, you have an incentive towards the fragmentation parties- status quo normal, to have lots of parties and coalition governments. That is an outcome of that underlying institutional groundwork. Single-member plurality system: leads to different predictions- usually a two party dominant type system. Part of how you explain the party system- look at the electoral system that produces incentives for parties. Kinds of parties we have- how it is that parties conduct themselves in the competititve arena they operate9elections. Spatial voting model: must understand electoral systems and voters to understand the party system- simple theory of voting behavior, how voters think and put out the prediction that the theory creates. This is about parties moderating- creation of moderate parties. The various party systems we have had across time in canada and set up, an election coming up in 2015.
