Four Other Potential Explanations

Show Summary Details


This chapter examines the influence of electoral system variables on disproportionality and various party system characteristics using comparable-case, cross-tabulation and regression analyses. These variables are ballot structure, apparentement, presidentialism, and malapportionment. The findings reveal that apparentement, ballot structure, and presidentialism are the most important influences on party system and disproportionality. The chapter concludes that of the all dependent variables, disproportionality can be best explained by the dimensions of the election system and that of all of the explanatory variables, the effective threshold is by far the best explainer.

Keywords: electoral system; disproportionality; comparable case; cross-tabulation; regression analysis; party system; ballot structure; apparentement; presidentialism; malapportionment
