  This letter analyzes coalition patterns among right-wing groups in the European Parliament, exploring the conditions that lead these groups to unite on policy. Using voting records from 2019 to 2024 and Legislative Observatory data, we identify three coalition types: Grand Right (all right-leaning groups), Far Right (excluding the center-right European People’s Party), and Center Right+ (including at least one far-right group). The potential for right-wing unity is substantial, particularly on EU Integration, climate, security, and cultural issues. For 2024–2029, two possibilities for right coalitions emerge: the European People’s Party allies with the far-right on cultural, climate, and security issues, challenging the European Parliament’s progressive stance, or the far-right joins the center-right on economic issues, normalizing right-wing influence in EU policymaking.

  In this chapter, we describe the institutional setting of parliamentary debate in Stortinget and identify correlates of speech participation, drawing on a dataset of more than a quarter of a million speeches from 1998 to 2016. The key correlate of speech participation is committee membership in the committee responsible for preparing the report for the topic under discussion. However, that is not the whole story. Party elites speak more than backbenchers. As speaking time is allocated proportional to party size, MPs from the smaller parties speak more often than their counterparts in the larger parties. While we uncover a gender difference in the overall allocation of speeches, this is only present amongst parties on the right of the political spectrum. We do not find a similar difference in length of speech or allocation of speeches amongst members within the same committee. Hence, we ascribe the gender difference in speeches to gender differences in committee composition.

  Most countries struggle to implement CO2 reducing policies. Implementation is politically difficult since it typically forces politicians to trade‐off different concerns. The literature on how parties and members of parliament (MPs) handle these trade‐offs is sparse. We use structural topic models to study how MPs in an oil dependent environment responded to a shock in the oil price that created spatially concentrated costs of climate policies. We leverage the rapid oil price drop between parliamentary sessions and MPs’ constituency adherence in a difference‐in‐differences framework to identify if MPs respond differently to variation in the salience of trade‐offs. We find that MPs facing high political costs of climate policies tried to avoid environmental topics, while less affected MPs talked more about investments in green energy when the oil price declined. Our results suggest that the oil price bust created a ‘window of opportunity’ for advocates of the ‘ green shift’.

  Committee coordinators face a classic delegation problem when assigning reports to their committee members. Although a few theoretical developments have focused on the effects of expertise on delegation, empirical studies have commonly assumed monotonic effects. Based on existing informational models, we argue that a more loyal committee member, everything else being equal, is more likely to be appointed as a rapporteur and that more expertise, holding preference divergence constant, has anon-monotonic effect because of informational credibility. Employing accumulated committee service as an expertise measure, these theoretical expectations are tested on all committee report delegations in the European Parliament from 1979 to 2014. Our empirical analysis with non-parametric and parametric hierarchical conditional logit models renders strong support for these expectations. The results hold across member states, political groups, procedures, committees and over time.

  What motivates politicians to engage in legislative activities? In multilevel systems politicians may be incentivized by ambitions to advance their careers either at the state or federal level. This article argues that the design of the electoral institutions influences how politicians respond to these incentives. Analyzing a unique dataset of both ‘stated’ and ‘realized’ career ambitions of Members of the European Parliament (MEPs), it finds that those who seek to move from the European to the national (state) level participate less in legislative activities than those who plan to stay at the European (federal) level. For MEPs who aim to move to the state level, attendance and participation in legislative activities is substantively lower among legislators from candidate-centered systems. Importantly, the effect of career ambitions on legislative participation is stronger in candidate-centered systems than in party-centered systems. These findings suggest that the responsiveness associated with candidate-centered systems comes at the expense of legislative activity.

  The early twentieth century saw many democracies adopt proportional representative systems. The textbook explanation, pioneered by Rokkan, emphasize between-party electoral competition; the rise of the Socialist vote share made Bourgeois parties prefer PR systems to maximize their seat share. While appealing, this account is not entirely compelling. Consequently, scholars are investigating within-party explanations of support for such reforms. Particularly, Cox, Fiva, and Smith show how list PR enable party leaders to discipline members and build cohesive parties. Relying on roll-call votes across the Norwegian 1919 electoral reform from two-round single-member plurality to closed-list PR, they show that the internal party cohesion increased following the reform. We investigate how the Norwegian electoral reform changed the content of parliamentary speeches. Comparing speeches from MPs present both before and after the reform, we show how parties become more cohesive in parliamentary debates under list PR than they were under the single-member-district system

  What explains the development of legislative party voting unity? Evidence from the United States and Britain indicate that partisan sorting, cohort replacement effects, electoral incentives, and agenda control contributed to enhancing party cohesion during the nineteenth and twentieth centuries. Here, these mechanisms are evaluated by analysing a dataset containing all the recorded votes from the Canadian House of Commons, 1867–2011. Overall, we find that partisan sorting and the government’s ability to control the agenda are central to the consolidation of parties over time. Our results underscore the need to integrate institutional rules and legislative agendas into models of parliamentary voting behaviour and suggest that strict party discipline can lead to the development of a multi-party system in the legislative arena.

  International index rankings are popular, but perhaps too persuasive. They emphasize country differences where similarity is the dominant feature. Rankings based on Doing Business, the Human Development Index and Freedom House can be misleading, not because of wrong indicators, but because the estimation of the scores ignores inherent uncertainty. Re-estimated with a method that captures this uncertainty, it becomes clear that ranking every adjacent country is a rather courageous activity.

  I extend the standard spatial model of legislative voting to account for vote-specific party inducements and procedural differences. Focusing on voting in the 1999—2004 European Parliament, I find evidence of vote-specific party inducements in a large share of the roll call votes. Furthermore, MEPs position themselves differently across procedures. As most roll call votes are taken on non-legislative votes, these estimates may overemphasize voting pattern on these votes and downplay voting pattern on legislative votes. As such, these estimates may be a poorly suited for studying within party heterogeneity on legislative votes.
