INTRODUCTION
What is the role of national parliaments in EU policy making? National parliaments are part of a complex multi-level governance system in the European Union and fulfill a crucial function for its democratic legitimacy (e.g., Auel & Christiansen 2015; Crum & Fossum 2009; Gattermann & Hefftler 2015; Meissner & Crum 2025; Rauh & De Wilde 2018). Accordingly, there is an ongoing academic debate about national parliaments’ effective role in EU policy-making processes. The literature focuses on several key aspects, such as the (changing) position of national parliaments and the related effects on democratic representation in the EU (e.g., Auel & Christiansen 2015; Leino-Sandberg & Raunio 2025; Pollak 2014; Raunio 2011; Winzen 2022); cross-national variation in national parliamentary behaviour (e.g., Gattermann & Hefftler 2015; Lehmann 2023; Raunio 2005); or the role perceptions of national MPs (e.g., Borońska-Hryniewiecka & Sacriste 2025; Kinski 2021a, 2021b). Despite this vibrant scholarly debate, we still lack a systematic understanding and large-scale comparative evidence on how national parliaments influence EU institutions and vice versa in policy making. Thus, we ask: Do debates in national parliaments drive issue attention and temporal priorities within the EU's multi-level system? Or do EU institutions, such as the European Commission, set the agenda and the political timescape (Meyer-Sahling & Goetz 2009)?
In principle, two main dimensions structure the EU’s multi-level system: a vertical and a horizontal dimension. The vertical dimension refers to the streams of influence between EU institutions and national parliaments or member states (e.g., Haverland & Liefferink 2012; Koop et al. 2022; Princen 2007, 2011). The horizontal dimension concerns the diffusion of policies and practices across national parliaments or member states (e.g., Blatter et al. 2021; Gilardi & Wasserfallen 2019; Gilardi et al. 2021; Kuhlmann 2021). Both dimensions are integral to understanding how policy making unfolds within the EU’s multi-level system.
To examine how national parliaments and EU institutions shape each other’s issue attention and temporal priorities, we employ the conceptual lenses of communicative agenda setting and, in particular, time setting. Communicative agenda setting refers to the process by which political actors influence, and compete over, which issues receive attention in the political system (McCombs & Shaw 1972; Green-Pedersen & Walgrave 2014). In parallel, we define communicative time setting as the process by which political actors influence, and compete over, when political action should be taken on specific issues. These concepts allow us to investigate whether national parliaments drive attention and set priorities for political action in the EU, or whether EU institutions are the primary driving forces.
RESEARCH DESIGN, DATA AND METHODS
In our study, we have assembled a large-scale comparative data set comprising a full corpus of national parliamentary speeches from the EU27 and the United Kingdom, as well as all public speeches by the European Commission – Commission Presidents and Commissioners – between 2009 and 2022. This novel data set enables us to investigate agenda-setting and time-setting dynamics between the European Union’s national parliaments and its key executive institution – the European Commission.
To map the salience of political issues – migration, health, and environmental protection – and the corresponding temporal preferences for political action in this large-scale corpus, we use state-of-the-art computational text analysis techniques. First, we apply open-source transformer-based models, fine-tuned on data from the Comparative Agendas Project (Sebők et al. 2024) to classify sentences from the individual parliamentary and Commission speeches into political issues. This allows us to detect the salience of migration, health and environmental protection in our speech corpus.
Second, we use zero- and few-shot classification with open-source Large Language Models (Alizadeh et al. 2025; Burnham et al. 2024; Laurer et al. 2024) to identify temporal preferences in the sentences. Specifically, we detect explicit calls for fast action, which represent the intended "fast” timing of a proposed policy response (Röth et al. 2024; Röth et al. 2025). In our conceptualization, such calls for fast action need to entail a reference to a social dynamic and to the timing of a policy response. For example, "We therefore need these common environmental goals, a joint approach, and a prompt decision” or "Asylum procedures should be carried out quickly…” would represent such calls for fast action in the areas of environmental protection and immigration respectively. Using zero- and few-shot classification models, we can reliably detect such invocations of time pressure in both parliamentary speeches and Commission speeches.
The resulting data offers unique insights into the structuration of key political debates at both the national and EU levels over time. Based on this data, we then statistically model the dynamics of agenda setting and time setting between member state parliaments and EU institutions. Using Vector Autoregression (VAR) models, we analyze who drives attention to political issues (i.e., agenda setting) and who shapes the temporal priorities of political action (i.e., time setting) across member states, the European Parliament, and the European Commission.
PRELIMINARY RESULTS
In this paper, we present initial results based on the analysis of parliamentary debates in Austria, Denmark, Germany, and Italy, as well as public speeches by the European Commission. Here, we primarily focus on communicative time setting between the selected national parliaments and the European Commission.
As a first step, we examine descriptive patterns in the data. Figure 1 illustrates the development of high time pressure invocations (i.e., calls for fast action) related to immigration between 2014 and 2017 – a period that covers the full trajectory of the European "refugee crisis.” The findings show that the Italian parliament was the first among the analyzed institutions to exhibit an increase in calls for fast action on immigration, with notable spikes as early as spring and autumn/winter 2014, as well as in spring 2015. The national parliaments of Austria and Germany followed some months later, with a marked increase in time pressure invocations during the summer and autumn of 2015. By contrast, the European Commission and Denmark began to invoke heightened time pressure only in autumn and winter 2015/16. These patterns correspond closely to the timing of refugee arrivals in each country and suggest a potential time-setting effect exerted by certain member states on the European Commission.

To more closely investigate these descriptive findings, we apply vector autoregression (VAR) models, which enable us to statistically model the reciprocal influence between national parliaments and the European Commission. In the case of immigration, the results suggest that national parliaments indeed exert a combined time-setting effect on the European Commission. Specifically, when national parliaments across the EU invoke increased time pressure on immigration (as measured by the pooled mean), the European Commission tends to issue more frequent calls for fast action in the subsequent months. We find little to no evidence for a reverse effect – i.e., the Commission does not appear to influence time pressure invocations on immigration in national parliaments. However, we also find substantial heterogeneity as the influence of individual national parliaments on the Commission varies considerably.

Similarly, we observe substantial variation when analyzing time-setting dynamics in the areas of environmental protection and health. In these policy domains, we find no consistent combined effect of national parliaments on the European Commission, nor any clear reverse effect. Instead, the results reveal significant variation across individual national parliaments. These findings underscore the need for further and deeper research to disentangle the time-setting dynamics between national parliaments and the European Commission across different policy areas.

DISCUSSION AND CONCLUSION
National parliaments play a crucial role for democratic legitimacy in the EU multi-level system, but our understanding of how and to what extent national parliaments influence EU institutions – and vice versa – in policy making remains limited. To close this gap, we have provided large-scale comparative evidence on how national parliaments can shape the timescape in the EU multi-level system. More precisely, we looked at communicative time setting – the process by which political actors influence and compete on when political action should be taken on specific issues.
Building on state-of-the-art computational text analysis techniques, our preliminary findings for the national parliaments of Austria, Denmark, Germany, and Italy, as well as the European Commission, have revealed the complexity of policy making in the European Union. While we have found that national parliaments (can) act as communicative time setters for the European Commission – i.e., shape the perception and invocation of time pressure by the European Commission – in the area of migration, this does not appear to apply to other policy domains (i.e., environmental protection, health). Furthermore, we find substantial variation across national parliaments.
These findings contribute to the ongoing debate about the role of national parliaments in the EU’s multi-level system. As central arenas of political discourse within the member states, national parliaments function as representative institutions for policy preferences. This also extends to temporal preferences for political action and the perception of time pressure on specific issues. In this way, national parliaments play a key role in shaping the timescape of European politics by communicatively influencing how time pressure is perceived – at least with regard to some political issues.
On a cautious note, however, and as discussed above, our current findings are based on a preliminary analysis of a specific sample of national parliaments (Austria, Denmark, Germany, and Italy). While this already yields valuable insights, our assembled data set also allows for a full analysis of all national parliaments from the EU27 and the United Kingdom. Combined with additional robustness checks, this broader analysis will provide a more comprehensive and reliable investigation of the underlying dynamics between national parliaments and the European Commission.
