CHOOSING ELECTORAL SYSTEMS - PROPORTIONAL, MAJORITARIAN AND MIXED SYSTEMS

Until recently electoral systems have usually proved remarkably resili ent to radical reform. Yet in the last decade this pattern has been br oken in a number of established democracies. The emergence of newer de mocracies has also generated a resurgence of interest in what criteria should be used in the choice of an electoral system. Given these deve lopments, the aim of this article is to outline the main variants in d ifferent types of electoral system; to consider the normative criteria underpinning debates about reform; and to evaluate the relevant stand ards for choosing an electoral system. The article compares legislativ e elections in 53 democracies, including countries at different level of economic and political development, in order to examine the effects of electoral systems under a wide variety of conditions.
