I am a PhD Candidate in Political Science at Trinity College Dublin and hold a Government of Ireland Postgraduate Scholarship from the Irish Research Council. Starting in January 2019 I am going to be a researcher in the Department of Political Science at the University of Zurich.
In my PhD thesis, I analyse the circumstances under which political parties and candidates decide to make promises, claim credit, or attribute blame. Combining crowd-sourced text annotation and quantitative text analysis, I focus on the coding of pledges, prospective and retrospective rhetoric in party manifestos, and media coverage of campaign promises throughout the electoral cycle.
In collaborative projects, I work on parties, public opinion, the incumbency advantage, legislative behaviour, and machine labelling of political text. My work has been published or is forthcoming in Political Science Research and Methods, Electoral Studies, and the Journal of Elections, Public Opinion and Parties.
Stefan Müller, and Tom Louwerse. Forthcoming. “The Electoral Cycle Effect in Parliamentary Democracies.” Political Science Research and Methods.
Does government party support decline in a monotonic fashion throughout the legislative cycle or do we observe a u-shaped ‘electoral cycle effect’? Moving beyond the study of midterm election results, this is the first study to assess the cyclical pulse of government party support in parliamentary democracies based on over 25,000 voting intention polls from 171 cycles in 22 countries. On average, government parties lose support during the first half of the electoral cycle, but at most partially recover from their initial losses. Under single-party government and when prime ministers control cabinet dissolution, support tends to follow the previously assumed u-shaped pattern more strongly. Finally, we find that government parties hardly recover from early losses since the 2000s.
Stefan Müller, and Michael Jankowski. 2018. “Do Voters Really Prefer More Choice? Determinants of Support for Personalised Electoral Systems.” Journal of Elections, Public Opinion and Parties (online first).
Which voters prefer having more choice between parties and candidates in an election? To provide an answer to this question, we analyse the case of a radical change from a closed-list PR system to a highly complex open-list PR system with cumulative voting in the German states of Bremen and Hamburg. We argue that the approval of a personalised electoral system is structured in similar ways as support for direct democracy. Using representative surveys conducted prior to all four state elections under cumulative voting in 2011 and 2015, we analyse which individual factors determine the approval, disapproval or indifference towards the new electoral law. The results indicate that younger voters as well as supporters of left parties are much more likely to support a personalised electoral system. In contrast to previous studies, political interest only has an impact on the indifference towards the electoral system. More generally, our results show that a large proportion of voters does not appreciate personalised preferential electoral systems which seems to be a result of the complexity and magnitude of choice between parties and candidates.

Many electoral systems constrain voters to one or two votes at election time. Reformers often see this as a failing because voters’ preferences are both broader and more varied than the number of choices allowed. New electoral systems therefore often permit more preferences to be expressed. In this paper we examine what happens when cumulative voting is introduced in two German states. Even when we allow for tactical considerations, we find that the principle of unconstrained choice is not widely embraced by voters, although in practice, too, many seem to have preferences for more than just one party. This finding has implications for arguments relating to electoral reform as well as how to conceive of party affiliations in multi-party systems.
The home advantage in various sports has been well documented. So far, we lack knowledge whether playing in neutral venues indeed removes many, if not all, theoretically assumed advantages of playing at home. Analysing over 3,500 Gaelic football and hurling matches – field games with the highest participation rates in Ireland – between 2009 and 2018, we test the potential moderating influence of neutral venues. In hurling and Gaelic football, a considerable share of matches in played at neutral venues. We test the influence of neutral venues based on descriptive statistics, and multilevel logistic and multinomial regressions controlling for team strength, the importance of the match, the year, and the sport. With predicted probabilities ranging between 0.8 and 0.9, the favourite team is very likely to win home matches. The predicted probability drops below 0.6 for away matches. At neutral venues, the favourite team has a predicted probability of winning of 0.7. A Coarsened Exact Matching (CEM) approach also reveals very substantive and significant effects for the ‘treatment’ of neutral venues. Overall, neutral venues appear to be an under-utilised option for creating fairer and less predictable competition, especially in single-game knock-out matches.
Politicians are often seen to combine the different goals of office-seeking, policy-seeking and vote-seeking (Müller and Strøm 1999). It can be hard for analysts to disentangle these sometimes competing, sometimes reinforcing, goals. Campaigns – and campaigning – are means by which candidates can, in principle, signal their motivations to voters. A candidate’s behaviour on the campaign trail should, then, be informative about their behaviour as a legislature and in particular, whether that candidate is policy-seeking or not. Using evidence from the European Parliament we show that campaign activity prior to the election does not indicate policy-seeking behaviour in the legislature post-election. The finding also holds in two national-level settings and across a variety of measures of legislative effort. These results suggests that campaigns may not always be good mechanisms for helping to select policy-seeking representatives.
quanteda is an R package providing a comprehensive workflow and toolkit for natural language processing tasks such as corpus management, tokenization, analysis, and visualization. It has extensive functions for applying dictionary analysis, exploring texts using keywords-in-context, computing document and feature similarities, and discovering multi-word expressions through collocation scoring. Based on entirely sparse operations, it provides highly effcient methods for compiling document-feature matrices and for manipulating these or using them in further quantitative analysis. Using C++ and multi-threading extensively, quanteda is also considerably faster and more effcient than other R and Python packages in processing large textual data.
“Prospective and Retrospective Rhetoric: A New Dimension of Party Competition and Campaign Strategies”. (Winner of the 2018 Manifesto Corpus Conference Best Paper Award)
Under what circumstances do political parties focus on intended future actions in campaign messages, and when do parties praise or criticize the past and the current situation? To measure the extent of ‘retrospective’ and ‘prospective’ campaign rhetoric, a comprehensively validated probabilistic classifier codes the temporal dimension of over 390,000 sentences from 576 manifestos in nine democracies. With a range between 19 and 92 per cent, on average around half of the sentences in party platforms contain a reference to the future. Ideologically extreme parties tend to put less emphasis on describing future actions than mainstream parties. Opposition parties, irrespective of ideology, frame the past and present much more negatively. However, almost all parties describe the future in a positive way. The similarities in prospective sections and differences in retrospective manifesto parts between government and opposition parties have important implications for theories of promissory representation, credit claiming, and responsibility attribution.
“Reassessing an Established Concept Through Crowd-Sourced Text Coding”.
A growing body of research analyses whether crowd-workers can reproduce the ‘gold standard’ of expert-generated data. Based on the case of election pledges, I show how crowd-coding can also test for differences in perceptions of a concept between groups of experts and instructed non-experts. The comparison of the most extensive reliability exercise among nine leading pledge researchers to over 1,900 codings generated by 60 crowd workers reveals considerable disagreement within and between both groups. Moreover, the carefully instructed and continuously monitored non-experts have a much broader understanding of election promises, which has serious consequences for analyzing pledge fulfillment. The approach illustrates that crowd-coding could be used across all subfields of political science to reassess the measurement validity of a concept.
“Media Coverage of Campaign Promises Throughout the Electoral Cycle”.
A growing body of work shows that governments fulfil a majority of their promises outlined in party manifestos. However, only a minority of voters believes that politicians try to keep their promises, and many voters struggle to accurately recall the fulfilment or breaking of salient campaign pledges. The public scepticism and often limited knowledge about pledges could be influenced by the information voters receive in news outlets. Based on a new text corpus of over 390,000 newspaper articles published during 35 electoral cycles in five established democracies, I show that media cover pledges throughout the entire cycle with peaks before and shortly after elections. Sentences without information on the fulfilment or breaking of a pledge constitute the largest share of coverage. I also find that the proportion of reports about broken promises is significantly and substantively larger than the proportion statements about fulfilled promises. The results have important implications for studying negative information in mass media, election pledges, and the linkage between voters and parties.
“Challenger Quality as a Moderator of the Incumbency Advantage in Personalized PR Systems” (with Michael Jankowski).
We address the question of how the quality of list competitors affects the incumbency advantage. We argue that incumbents are less likely to benefit from holding office when list competitors are well-known and of high quality. To test this mechanism, we exploit the special ‘dual mandate’ characteristic of Irish local elections. Until 1999, members of the national parliament (TDs) were allowed to be represented in local and national parliaments simultaneously. By applying the regression discontinuity design to local elections between 1942 and 2014, we demonstrate that marginally elected politicians perform significantly worse when a TD competes for votes on the same list. Moreover, the incumbency advantage has become larger after the dual mandate was abolished. Our results highlight the moderating impact of high-quality competitors on the incumbency bonus.
