(2017) Outsiders at the Ballot Box: Operationalizations and Political Consequences of the Insider-Outsider Dualism  

Socio-Economic Review 

(with Allison E. Rovny)

Recently, developed economies have witnessed an emerging dualism between the so-called labor market ‘insiders and outsiders’—two groups facing divergent levels of employment security and prospects. Those on the ‘inside’ occupy stable jobs, while those on the ‘outside’ confront increased levels of social and economic risks. There are, however, various prominent, but divergent, operationalizations of the insider–outsider phenomenon. While some scholars opt for indicators rooted in current labor market status of individuals, others prefer to consider occupational class groups as bases of the insider–outsider divide. As these operationalizations of outsiderness capture different profiles of outsiders, we test the extent to which they lead to consistent or inconsistent conclusions about electoral behavior. The article yields two consistent findings that are robust across all the operationalizations: that outsiders are less likely to vote for major right parties than are insiders, and that out- siders are more likely to abstain from voting. Additionally, we find that occupation-based outsiders tend to support radical right parties, while status-based outsiders rather opt for radical left parties—a finding supported by the association between social risk and authoritarian preferences. We test our expectations using multinomial logit models estimating vote choice on the first five waves of the European Social Survey from 2002 to 2010 across western Europe. 


(2016) Stepping in the same river twice: Stability amidst change in Eastern European party competition 

European Journal of Political Research

(with Jonathan Polk) 

Party competition in Eastern Europe faces a seeming paradox. On the one hand, research finds increased political volatility in these countries, while, on the other, some authors demonstrate inherent ideological stability in the region. This research note presents a new methodological approach to adjudicating between these two findings, and suggests that while political organisations come and go, the ideological structure of party competition in Eastern Europe is strikingly steady. By developing a number of different measures of the dimensional structure of party competition, the consistency of the measures across countries, as well as their relative stability within countries over time, is demonstrated. The findings speak to current developments in Eastern Europe, and have implications beyond the region. The conclusion that even volatile party systems can be underpinned by stable ideological oppositions points to two different types of party system structure: one related to parties as organisations, and the other related to parties as expressions of political divides. 


(2015) Riker and Rokkan: Remarks on the Strategy and Structure of Party Competition

Party Politics 21(6)

This special issue studies the strategic interaction between major state-wide and regional parties in a political setting defined by multiple, potentially cross-cutting, political issues pertaining to the economy and the territorial organization of multi-national states. Through this framework, this special issue locates itself decisively in the behaviorist tradition of studying political competition. Stemming from the classical works of Riker and the Rochester school, and focusing on rational choice models, this tradition has influenced a lively literature on party strategies. This concluding article of the special issue argues that the findings of the substantive contributions create a bridge between the strategic, Rikerian literature they stem from and seek to engage with, and more sociological approaches to the study of political parties that focus on the structural features of politics reaching back to the works of Lipset and Rokkan. I suggest that, ultimately, this special issue demonstrates the socially, historically and institutionally bounded opportunities of political parties. Fundamentally, the special issue makes a significant contribution to the strategic literature by suggesting structural limits to strategic behavior.


(2015) Party Competition Structure in Eastern Europe:  Aggregate Uniformity versus Idiosyncratic Diversity?

East European Politics and Societies 21(9) 

The literature on party competition structure in eastern Europe varies between aggregated large-N studies that propose uniform patterns of party competition across the region on the one hand, and disaggregated, case-focused studies identifying a plurality of country-specific patterns on the other. This article finds that both suffer from theoretical weaknesses. The aggregated works, arguing for common unidimensionality of party competition in the region, overlook significant cross-national differences, while the case-focused works, suggesting country-specific multi-dimensionality, do not identify commonalities. In effect, both sets of research fall short in explaining the variance of the party competition in eastern Europe. This article consequently argues for the importance of bridging these findings of aggregate uniformity and idiosyncratic diversity through the use of refined theoretical explanations of party competition patterns in the region. To demonstrate the plausibility and utility of such an approach, the article builds a theoretical model of party competition in eastern Europe and tests it by estimating the vote for left-wing parties across ten eastern European countries using the 2009 European Election Study.


(2015) Measuring Party Positions in Europe. The Chapel Hill Expert Survey Trend File 1999-2010

   (with Ryan Bakker, Catherine de Vries, Erica Edwards, Liesbet Hooghe, Seth Jolly, Gary Marks, Jon Polk, Marco Steenbergen and Milada Anna Vachudova)

Party Politics 21(1)

Chapel Hill Expert Survey Data 

This article reports on the 2010 Chapel Hill expert surveys (CHES), and introduces the CHES trend file, which contain measures of national party positioning on European integration, ideology, and several European Union (EU) and non-EU policies for four waves of the survey, from 1999−2010. We examine the reliability of expert judgments and cross-validate the 2010 CHES data with data from the Comparative Manifesto Project and the 2009 European Elections Studies survey. The dataset is available on the CHES website.


(2014) Anchoring the Experts: Using Vignettes to Compare Party Ideology Across Countries 

(with Ryan Bakker, Erica Edwards, Seth Jolly, Jon Polk and MarcoSteenbergen)

Research and Politics  November-December

Expert surveys have emerged as a valuable instrument to measure party positions in modern democracies (cf. Ray 1999; Benoit and Laver 2006; Hooghe et al. 2010). Some critics question the cross-national comparability of these measures, though, suggesting that expert surveys may lack a secure, common anchor for fundamental concepts such as economic left-right. In short, experts could be using what it means to be centrist in the expert’s own country as the reference point, but centrist in Norway could be more left- leaning than centrist in Italy. Taken to its logical extreme, this problem could confound cross-country comparison. This article analyzes vignette data from the 2010 Chapel Hill Expert Survey (CHES) specifically designed to address this concern. In the survey, experts placed hypothetical and real parties on a series of eleven point scales, which allow an assessment of the extent to which experts in 26 different countries evaluate party positioning with a common metric. We document evidence of cross-national difference in expert ideological placements, especially in some Scandinavian countries. However, in modeling economic left-right with substantive variables of interest with the 2010 CHES data, we find that these rather small country-specific differences do not bias expert placements in a systematic way. Our findings, therefore, provide an important piece of evidence in establishing expert surveys as a rigorous instrument for measuring party positions in a cross-national context.


(2014) Communism, Federalism and Ethnic Minorities: Explaining Party Competition Patterns in Eastern Europe

World Politics 66 (4)

Supporting Material                    Addendum

Scholarship on eastern European politics expects that party competition in the region is determined by various communist legacies, juxtaposing state-centric authoritarianism to democratic market economy. Recent empirical evidence, however, uncovers significant variance of party competition patterns across eastern European countries. To explain this variance, this article argues that an interaction between communist institutional framework and partisan responses to ethnic minorities determine party competition structure in eastern Europe. While experience with communist federalism determines partisan affinities with ethnic minorities, tolerance or support for ethnic minorities leads to general social liberal positions. Consequently — and contrary to received knowledge — ethnic politics influence the ideological content of party competition, and structure party systems in eastern Europe.     



(2014) The Other ‘Other’: Party Responses to Immigration in Eastern Europe

Comparative European Politics 12 (6)

Eastern Europe has traditionally been a region of emigration, sending thousands of refugees and migrants to the more developed and democratic west. The recent democratization and rising affluence of some eastern European countries, however, make them increasingly attractive destinations of migrant workers, slowly but surely turning them into immigrant societies. This paper addresses the responses of political parties to the issue of immigration and immigrant integration. Through large-N quantitative analyses of eleven eastern European countries using the Chapel Hill Expert Surveys, the 2009 European Election Study, the Database of Political Institutions and World Bank indicators, it analyzes the causes of immigration salience, as well as the reasons behind immigration and integration policy positions. The paper argues that partisan and voter views on immigration in eastern Europe are guided by ideological views on ethnic minorities, which have been the traditional ‘out-groups’ in the region. Partisan positions on immigration and immigrant integration are consequently determined by underlying ideological principles concerning cultural openness and acceptance of ‘otherness’. Immigrants to eastern Europe are consequently viewed as the other ‘other.’


(2013) Where do Radical Right Parties Stand?Position Blurring and Dimensional Competition 

European Political Science Review  5(1)

This article questions the utility of assessing radical right party placement on economic issues, which has been extensively analyzed in academic literature. Starting from the premise that political parties have varying strategic stakes in different political issues, the article considers political competition in multiple issue dimensions. It suggests that political competition is not simply a matter of taking positions on political issues, but rather centers on manipulating the dimensional structure of politics. The core argument is that certain political parties, such as those of the radical right, seek to compete on neglected, secondary issues, while simultaneously blurring their positions on established issues in order to attract broader support. Deliberate position blurring -- considered costly by the literature -- may thus be an effective strategy in multidimensional competition. The article combines quantitative analyses of electoral manifestos, expert placement of political parties, and voter preferences, by studying seventeen radical right parties in nine Western European party systems.


(2012) Who Emphasizes and Who Blurs? Party Competition in Multiple Dimensions 

European Union Politics. 13(2)

Most studies consider the presentation of ambiguous positions a costly strategy. This literature, however, does not study party strategies in multiple issue dimensions. Yet multidimensionality may play an important role in partisan strategic calculus. While it may be rational for a party to emphasize a certain issue dimension, it may be equally rational to disguise its stance on other dimensions by blurring its positioning. This article argues that parties employ strategies of issue emphasis and position blurring in various dimensional contexts. Who emphasizes and who blurs thus depends on the actors’ relative stakes in different issue dimensions. The paper makes its case by performing cross-sectional analyses of 132 political parties in 14 Western European party systems using Comparative Manifesto Project data, the 2006 Chapel Hill expert survey and the 2009 European Election Study.


(2012) Struggle Over Dimensionality: Party Competition in Western and Eastern Europe

(with Erica Edwards).  

East European Politics and Societies 26(1) 

This article analyzes the impact of party strategies on the issue structure, and consequently the dimensional structure, of party systems across europe. Conceptualizing political competition in two dimensions (economic left-right and social traditionalism versus liberalism), the authors demonstrate that political parties in both eastern and Western europe contest the issue composition of political space. The authors argue that large, mainstream parties are invested in the dimensional status quo, preferring to compete on the primary dimension by emphasizing economic issues. Systematically disadvantaged niche parties, conversely, prefer to compete along a secondary dimension by stressing social issues. adopting such a strategy enables niche parties to divert voter attention and challenge the structure of conflict between the major partisan competitors. The authors test these propositions using the 2006 iteration of the Chapel Hill expert Surveys on Party Positions. Findings indicate that while the structure of political conflict in eastern versus Western europe could not be more different, the logic with which parties compete in their respective systems is the same. The authors conclude that political competition is primarily a struggle over dimensionality; it does not merely occur along issue dimensions but also over their content.
