This article provides a detailed set of coding rules for disaggregating electoral volatility into two components: volatility caused by new party entry and old party exit, and volatility caused by vote switching across existing parties. After providing an overview of both types of volatility in post-communist countries, the causes of volatility are analysed using a larger dataset than those used in previous studies. The results are startling: most findings based on elections in post-communist countries included in previous studies disappear. Instead, entry and exit volatility is found to be largely a function of long-term economic recovery, and it becomes clear that very little is known about what causes ‘party switching’ volatility. As a robustness test of this latter result, the authors demonstrate that systematic explanations for party-switching volatility in Western Europe can indeed be found.

Abstract This article examines the electoral impact of spillover effects in local campaigns in Britain. For the first time, this is applied to the long as well as the short campaign. Using spatial econometric modelling on constituency data from the 2010 general election, there is clear empirical evidence that, in both campaign periods, the more a party spends on campaigning in constituencies adjacent to constituency i, the more votes it gets in constituency i. Of the three major political parties, the Liberal Democrats obtained the greatest electoral payoff. Future empirical analyses of voting at the constituency scale must, therefore, explicitly take account of spatial heterogeneity in order to correctly gauge the magnitude and significance of factors that affect parties' parliamentary performance.

Abstract Under evaluative voting, the voter freely grades each candidate on a numerical scale, with the winning candidate being determined by the sum of the grades they receive. This paper compares evaluative voting with the two-round system, reporting on an experiment, conducted during the 2012 French presidential election, which attracted 2,340 participants. Here we show that the two-round system favors “exclusive” candidates, that is candidates who elicit strong feelings, while evaluative rules favor “inclusive” candidates, that is candidates who attract the support of a large span of the electorate. These differences are explained by two complementary reasons: the opportunity for the voter to support several candidates under evaluative voting rules, and the specific pattern of strategic voting under the two-round voting rule.

Do parties with different ideological origins adjust their policies in response to the binding commitments that derive from the European integration process? This paper examines whether party platforms have adapted to the ideological content of EU treaty provisions – based on ‘neoliberalism’ and ‘regulated capitalism’ – across a range of policy areas The analysis builds on existing research which has examined how party families respond to the challenges and opportunities of the integration process. This is the first study that focuses on long-term party policy adjustment across different policy areas by examining whether there has been a shift away from core ideological goals towards the direction of EU policy. The main finding is that there has generally been a shift towards the direction of EU policy across all party families in both member and non-member states. The findings have implications for the quality of representation and functioning of democracy in the member states since the deepening of the European integration process reduces ideologically distinct policy alternatives across party families and can hinder policy innovation

Although the over-representation of working-class members among the electorates of Extreme Right Parties (ERPs) in Western Europe is well documented, previous studies have usually explained this pattern as a result of this voter group's changing political preferences. In contrast to these studies, this article argues that it is not the changing political preferences of the working class that lead them to vote for ERPs, but changes in the supply side of party competition that have caused the re-orientation of these voters from left-wing parties toward the extreme right. Differentiating between an economic and a cultural dimension of party competition, it is shown that both the policy options offered by parties to voters as the salience of the two issue-dimensions have changed dramatically over the last three decades. While the salience of economic issues as well as of party system polarization among these issues have declined in most Western European countries, the very opposite trend can be identified for non-economic issues, including the core issues of ERPs (for example, immigration, and law-and-order). These changes on the supply side of party competition cause working-class voters to base their vote decisions solely on their authoritarian, non-economic preferences and not – as in the past – on their left-wing economic demands. The theoretical assumptions are tested empirically with data from the Eurobarometer Trend File for the period from 1980 to 2002. In contexts where the economic dimension is more polarized or more salient than the cultural dimension, the positive impact of being a member of the working class on the vote decision for an ERP is significantly reduced.
