The international diffusion of electoral systems: The spread of mechanisms tempering proportional representation across Europe

There is an assumption in much of the electoral engineering literature that domestic episodes of electoral system choice occur in a vacuum, isolated from international influences. Yet this assumption remains largely untested, despite the comparative focus of much of that literature. This article focuses on part of this gap by considering two electoral mechanisms that seek to limit party system fragmentation under proportional representation – low district magnitudes and high electoral thresholds – and shows that the mechanisms have spread across many European countries during the post‐1945 period. Analyses reveal that national legislators are more likely to adopt one of these electoral mechanisms when a large number of peer countries have made similar choices within the last two or three years. This effect is robust to various model specifications and to the inclusion of multiple controls. The article also offers some qualitative evidence from case studies and parliamentary debates.     

Electoral volatility and the dynamics of electoral reform

Recent elections in Europe have shown that a context of increasing citizen distrust towards democratic institutions may lead to very high levels of electoral volatility and to the emergence of new parties. On the other hand, institutional reforms are sometimes presented as a solution to citizens’ discontent with political institutions. Focusing on a specific type of political institution ? electoral systems ? the question addressed in this study is whether high levels of electoral volatility may trigger electoral reforms. The article investigates the conditions under which reforms affecting the electoral system’s degree of openness to new parties were enacted in 25 European countries between 1945 and 2012. The findings demonstrate that volatility due to the emergence of new parties is the most powerful explanation to account for the introduction of electoral reforms, particularly those that hinder the entry of new parties into the system.     

Electronic Voting in Belgium: A Legitimised Choice?

Computer voting was introduced in Belgium in 1994. Paradoxically, no action had been taken to ascertain the opinion of electors confronted with this original method of voting. This article verifies the social and empirical dimensions of legitimacy of this new method through several empirical indicators used in a survey conducted on the occasion of the federal elections of 18 May 2003: (a) how easy/difficult it was for electors to vote on a computer; (b) to what extent they trust voting on a computer; (c) if they have a philosophical/social opposition to voting on a computer.
