Crisis Leadership Approval: The Opposing Effects of Perceived Threat and Anxiety
In times of crisis, citizens tend to increase their approval of the government and its leader which might shift the balance of power. This ‘rally effect’ is a persistent empirical regularity, however, the literature does not identify its underlying causal mechanisms. We argue that crises induce threat and anxiety, and theorize that perceived threat increases approval of the incumbent leader, whereas anxiety decreases it. By analyzing German panel data from the COVID-19 pandemic, we causally identify both mechanisms and provide systematic evidence supporting this theory. Moreover, we increase the scope of our theory and show that both mechanisms are also at work when citizens approve cabinet members who manage key port- folios. Finally, we also leverage a comparative survey design across eleven countries to show that our evidence generalizes beyond a single country. Our findings have highly important implications for our understanding of the rally effect and crises politics in democracies.

How Voters React to Parties Breaking their Pre-Electoral Coalition Promises: Experimental and Quasi-Experimental Evidence from Ireland and New Zealand
In proportional systems, parties generally signal their coalition preferences to voters during election campaigns. Breaking coalition promises after the election entails normatively undesirable repercussions for government identifiability and accountability. This study is the first to investigate voters’ short-term reactions to post-electoral coalition choices of parties in conflict with pre-electoral coalition signals. Firstly, I performed a quasi-experimental investigation that considers an instance of inconsistent coalition choice following the 1996 New Zealand election. Secondly, I conducted an innovative survey experiment during the government formation period following the 2020 Irish general election. I find that breaking coalition promises is costly not only for the inconsistent party but also for democracy in general. Inconsistencies concerning coalition choices make voters less likely to support the inconsistent parties and erode voters’ satisfaction with the way democracy works. The findings provide important implications for government identifiability and accountability in proportional systems, democratic stability, and the effectiveness of

Unintended Effects of Cordons Sanitaires on the Electoral Success of Isolated Parties: Counterfactual Agent-Based Simulations in an Artificial Weimar Republic with Coalition-Directed Voters
Ruling out forming coalition governments with parties critical of liberal democracy, i.e., establishing
cordons sanitaires
vis-à-vis these parties, is often seen as a crucial contribution to safeguarding liberal democracy. However, little is known about whether
cordons sanitaires
are effective in reducing the vote share of parties isolated in this way. Specifically, the effects of
cordons sanitaires
on voting induced by changes in voters’ expectations of post-electoral government formation remain unclear. I address this research gap by conceptualizing
cordons sanitaires
as a specific class of pre-electoral coalition signals and drawing on theoretical knowledge about the electoral expectation-induced consequences of coalition signals. I integrate these theoretical insights into a formal agent-based model of dynamic party competition and perform counterfactual simulations in an artificial democracy calibrated to resemble the 1930s Weimar Republic. The results show that the vote share of an artificial NSDAP increases when a
cordon sanitaire
is erected against it. By illustrating the theoretical possibility (not inevitability) of these unintended expectation-induced consequences, the paper provides important implications for research on the mainstream parties’ response to radical parties.

Observing Many Researchers Using the Same Data and Hypothesis Reveals a Hidden Universe of Uncertainty
This study explores how researchers’ analytical choices affect the reliability of scientific findings. Most discussions of reliability problems in science focus on systematic biases. We broaden the lens to emphasize the idiosyncrasy of conscious and unconscious decisions that researchers make during data analysis. We coordinated 161 researchers in 73 research teams and observed their research decisions as they used the same data to independently test the same prominent social science hypothesis, namely that greater immigration reduces support for social policies among the public. In this typical case of social science research, research teams reported both widely diverging numerical findings and substantive conclusions despite identical start conditions. Researchers’ expertise, prior beliefs, and expectations barely predict the wide variation in research outcomes. More than 95% of the total variance in numerical results remains unexplained even after qualitative coding of all identifiable decisions in each team’s workflow. This reveals a universe of uncertainty that remains hidden when considering a single study in isolation. The idiosyncratic nature of how researchers’ results and conclusions varied is a previously underappreciated explanation for why many scientific hypotheses remain contested. These results call for greater epistemic humility and clarity in reporting scientific findings.

Coalition-Directed Voting as a Lottery
When voters support parties in multi-party democracies, it is often uncertain what coalition government the party is likely to join. How do voters deal with this type of uncertainty? In this paper, we use a conceptual analogy between coalition-directed voting and participating in a lottery to develop a novel conceptualization of coalition- directed voting. We present observational and experimental evidence that supports the idea that voters are risk-averse when considering coalition government options. The perception of uncertain coalition prospects of a party negatively affects the propensity to vote for parties, even when holding the expected coalition government payoffs constant. In a survey vignette experiment during the 2021 German federal election, we find that uncertain coalition prospects reduce the propensity to support a party, compared to certain coalition prospects with the same expected coalition government payoffs. The findings provide important insights for research on strategic voting theories and parties’ coalition strategies.

Measuring Inter-Party Communication: A Transfer Learning Approach
Inter-party communication is crucial in representative democracies, enabling in- formation exchange and dialogue among political parties. Despite its importance, research on this topic remains limited due to a lack of comprehensive conceptualization and challenges in large-scale measurement. This article proposes a holistic definition of inter-party communication as public communication by parties about others with a positive, neutral, or negative stance, focusing on collaboration, policy, or personal issues. To effectively measure inter-party communication, we introduce a novel transfer learning approach capable of automatically classifying large volumes of textual data. Two case studies on coalition signals in Germany and negative campaigning in Austria demonstrate its effectiveness. The study contributes to our understanding of political discourse and the dynamics of party competition. Our approach advances automatic text classification methodologies and opens new avenues for studying political communication.

Come Hither or Go Away? Recognising Pre-electoral Coalition Signals in the News
In this paper, we introduce the task of political coalition signal prediction from text, that is, the task of recognizing from the news coverage leading up to an election the (un)willingness of political parties to form a government coalition. We decompose our problem into two related, but distinct tasks, namely (i) predicting whether a reported statement from a politician or a journalist refers to a potential coalition and (ii) predicting the polarity of the signal – namely, whether the speaker is in favour of or against the coalition. For this, we explore the benefits of multi-task learning and investigate which setup and task formulation is best suited for each sub-task. We evaluate our approach, based on hand-coded newspaper articles, covering elections in three countries (Ireland, Germany, Austria) and two languages (English, German). Our results show that the multi-task learning approach can further improve results over a strong monolingual transfer learning baseline.

An Agent-Based Approach to Estimate Social Interaction Effects on Government Satisfaction in Germany
This study formulates and tests an agent-based model of opinion dynamics which claims to explain the evolution of political preferences by means of social interaction effects. The approach incorporates a majority and a momentum mechanism claiming that individuals are affected by perceived opinion levels as well as by opinion changes. This theoretical model is empirically tested by estimating its parameters on government satisfaction in Germany. The results support the empirical validity of the approach, as a significant momentum mechanism can be identified while other significant parameters display meaningful estimates. Additionally, almost every week’s level of government satisfaction is a likely realization of the process given the data of the previous week. Beyond that, the findings suggest that individuals are rather affected by opinion changes than by opinion levels and that nonconformity plays a more important role in the evolution of the considered preference than conformity.

Comparing Political Discourses in Print and Online Media: An Empirical Analysis of the German Renewable Energy Act Amendment 2014
With the emergence of digital technologies, the mass media exploited new distribution channels. This differentiation of communication platforms led to a fragmentation of the public sphere. Based on a comparative discourse analysis on the German Renewable Energy Act Amendment 2014, including both print and online media, this article investigates the influence of media platforms on the public discourse. We find that, in our application, the online and print discourses differ significantly from each other with regard to both the standing of actors and the framing of the main arguments. This variation is on a similar level to the differences between newspaper publishers. Despite this variation, the main structures of the print media and the online media discourses do not differ fundamentally.
