“…Supplemental Appendix A categorizes all parties by election. Second, I apply Prosser’s (2014) validated scaling approach to identify the (L)eft-(R)ight content of party electoral programs (on a 11-point spectrum) using data from the Manifesto Project on Political Representation [MARPOR] (Volkens et al, 2019). Supplemental Appendix B further details the workings of MARPOR and lists Prosser’s “left” and “right” manifesto positions.…”

Crisis and Convergence: How the Combination of a Weak Economy and Mainstream Party Ideological De-Polarization Fuels Anti-System Support

When do radical parties gain support? Previous studies cite the economy and mainstream party ideological convergence as important. Responding to earlier inconsistent findings, I provide evidence for an interactive approach. Anti-system parties succeed when mainstream parties are simultaneously presiding over an ailing economy and failing to provide the diversity of political opinion for the electorate to meaningfully challenge the policies associated with this malaise, through which dissatisfaction with the status quo could otherwise be channeled. Two studies support this “crisis and convergence” model. At the aggregate-level, the anti-system vote is strongest during times of negative economic growth and widespread mainstream party ideological de-polarization. At the voter-level, the link between negative economic evaluations and radical party voting is stronger during establishment convergence and, vice versa, personal perceptions of convergence are themselves more closely related to support for these parties when the macroeconomy is sickly. Mainstream party homogeneity radicalizes the economic vote and strengthens anti-system challengers.

Dimensionality, ideology and party positions towards European integration

The rise of political contestation over European integration has led many scholars to examine the role that broader ideological positions play in structuring party attitudes towards European integration. This article extends the existing approaches in two important ways: 1) It shows that whether the dimensionality of politics is imagined in a one dimensional 'general left-right' form or a two dimensional 'economic left-right/social liberal-conservative' form leads to very different understandings of the way ideology has structured attitudes towards European integration, with the two dimensional approach offering greater explanatory power. 2) Existing approaches have modelled the influence of ideology on attitudes towards European integration as a static process. This article shows that the relationship between ideology and European integration has changed substantially over the history of European integration: divisions over social issues have replaced economic concerns as the main driver of party attitudes towards European integration.

“…We follow customary practice and derive a position estimate by subtracting left from right percentages. A drawback of building the difference is that the estimate is not “independent of irrelevant alternatives” because changes in the number of quasi-sentences not feeding directly into the economic position estimate might affect that estimate ([61], p. 91). We address this problem and standardize the difference between right and left number by dividing it with the sum of the right and left percentages: (R-L)/(R+L) [62].…”

The time-varying relationship between economic globalization and the ideological center of gravity of party systems

Does economic globalization influence the positioning of parties and, as a consequence, the ideological characteristics of party systems? Answering this question is important because we need to understand the constraints that parties face in formulating policies from which voters have to choose. In our paper, we take a systemic perspective and conceptualize a party system’s ideological center of gravity as the outcome of interest. We define the center of gravity as the weighted mean position of all parliamentary parties in a country that represents the position to which parties gravitate. We start by formulating static hypotheses on the effect of imports and exports on the center of gravity and derive their underlying mechanisms. We further derive dynamic hypotheses stipulating varying effects over time based on the premise that partisan attitudes toward globalization have undergone multiple changes over the last decades. A time-series cross-section analysis of 129 elections in 15 Western European countries from 1974 to 2015 finds evidence for opposite effects of exports and imports in the pooled data. Additionally, a moving-window analysis indicates that the relationship between globalization and the center of gravity varies over time. This is a significant finding because it suggests that economic globalization has an influence on party systems and that it is important to test for time-varying effects.
