Choosing Electoral Systems: Proportional, Majoritarian and Mixed Systems

Abstract

Until recently electoral systems have usually proved remarkably resilient to radical reform. Yet in the last decade this pattern has been broken in a number of established democracies. The emergence of newer democracies has also generated a resurgence of interest in what criteria should be used in the choice of an electoral system. Given these developments, the aim of this article is to outline the main variants in different types of electoral system; to consider the normative criteria underpinning debates about reform; and to evaluate the relevant standards for choosing an electoral system. The article compares legislative 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.
