Changes in Election Rules between Systems in the Same Country

Show Summary Details


This chapter discusses the changes in election rules between electoral systems in the same country using the comparative method of analysis. This method of controlled comparison focuses on comparable cases or cases that differ with regard to the variables one wants to investigate, but which are similar with regard all other important variables that may affect the dependent variables. The chapter explains the correlation between the controlled changes in electoral formula and effective threshold, and the changes in disproportionality and effective numbers of parties. It concludes that even when the electoral systems include a long series of elections, they tend to have a high degree of internal uniformity.

Keywords: election; electoral system; comparative method; electoral formula; effective threshold; political parties
