This paper bridges these two previously isolated strands, exploring how macro-institutions influence policy processes. Specifically, we investigated how political institutions, such as decentralization and corporatism, relate to coalition opportunity structures (COSs), a key concept within the advocacy coalition framework (ACF); we also investigated the role of minority coalitions and subsystem collaboration. Empirically, we based our analysis on prototypes selected according to Aranda Lijphart's models of majoritarian and consensus democracies. Drawing on existing comparative ACF applications related to climate, water, and energy policy processes, we compared results from these studies to assess the impact of institutional settings on coalition dynamics. Our findings suggest that minority coalitions are more present—and sometimes more influential—in federalist than in unitary countries and that corporatism has a greater effect on collaboration within policy subsystems than consensualism.</p></div>","PeriodicalId":52190,"journal":{"name":"European Policy Analysis","volume":"11 2","pages":"254-270"},"PeriodicalIF":2.7,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144135621","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This iterative model starts from the Commission's ideal stance and persists until no member state challenges a policy position, which then becomes the adopted outcome. The European Parliament contributes to shaping the trajectory from the Commission's proposal to the final result.

Weible","doi":"10.1002/epa2.70002","DOIUrl":"https://doi.org/10.1002/epa2.70002","url":null,"abstract":"&lt;p&gt;About a quarter century ago, Paul Sabatier brought together what he considered the most promising and useful theoretical approaches to studying policy processes in the inaugural edition of the &lt;i&gt;Theories of the Policy Process&lt;/i&gt; (Sabatier, &lt;span&gt;1999&lt;/span&gt;). This seminal work featured contributions exclusively from U.S.-based scholars and reflected the U.S. political setting—characterized by majoritarianism, pluralism, federalism, and a strong emphasis on individualism. A year later, the &lt;i&gt;European Journal of Public Policy&lt;/i&gt; published a symposium critically examining the relevance of these policy process theories in the European context (Dudley et al., &lt;span&gt;2000&lt;/span&gt;). The symposium questioned the volume's content, its scientific orientations, and the suitability of its theories for understanding the distinctive context of European countries and the European Union.&lt;/p&gt;&lt;p&gt;Fast-forward to today, the fifth edition of the &lt;i&gt;Theories of the Policy Process&lt;/i&gt; has been published (Weible, &lt;span&gt;2023&lt;/span&gt;). While the roster of theories has evolved—with some added and others removed—the foundations of the collection remain rooted in U.S. policy processes. That said, the scope and perspectives have broadened significantly. All but two chapters now feature European co-authors, and the text engages questions of the growing applicability of the theories across diverse policy domains and governing settings, from authoritarian regimes to democracies (e.g., Tosun &amp; Workman, &lt;span&gt;2023&lt;/span&gt;).&lt;/p&gt;&lt;p&gt;This special in &lt;i&gt;European Policy Analysis&lt;/i&gt; revisits the themes in Dudley et al. (&lt;span&gt;2000&lt;/span&gt;) about the relevance of policy process theories for studies in European countries and the European Union. The contributing authors present a comprehensive exploration of policy process theories—past, present, and future—with a particular focus on European applications and their broader impacts. It begins with Claudio Radaelli, a coauthor of Dudley et al. (&lt;span&gt;2000&lt;/span&gt;), who reflects on the evolution of policy process theories over the decades, drawing from his career in the field. In contrast, Paul Cairney et al. (&lt;span&gt;2025&lt;/span&gt;) provide a contemporary snapshot that includes a survey of scholars recently applying these theories in Europe. Related to theoretical impacts, Evangelia Petridou et al. (&lt;span&gt;2025&lt;/span&gt;) delve into a cross-cutting concept—policy entrepreneurs—conducting a systematic review to highlight insights from European applications.&lt;/p&gt;&lt;p&gt;The subsequent contributions tackle the challenges and gaps in integrating context into policy process theories. Zohlnhöfer and Herweg (&lt;span&gt;2025&lt;/span&gt;) address three underexplored concepts in European applications—political parties, macro-level institutions, and Europeanization—calling for their greater inclusion.

This applies both to the long-term economic and social challenges in Europe and to short-term and temporary crises, although they have to be treated very differently (Mavrot et al., <span>2024</span>). With regard to lessons learned and future resilience, it is important to systematically analyze the experiences of past crises such as the COVID-19 pandemic. Policy process research can make an important contribution here, particularly with regard to the role of science in the policy process (Capano et al., <span>2024</span>; Chen &amp; Zhang, <span>2024</span>; Hadorn et al., <span>2022</span>; Weible et al., <span>2020</span>). One of the important lessons learned was the special role of scientists not only in advising politicians but also in political communication. Here, Switzerland's small federal democracy, with its special direct democratic elements offers a special environment. Ksinsik (<span>2025</span>) combines concepts of science communication with the Narrative Policy Framework in a paper that has won the Best Paper Award of the ECPR Standing Group of Public Policy. The study looks at the special way Swiss scientists worked with policy discussions during the pandemic. It uses an index from NPF research to measure the devil-angel shift (Chang &amp; Koebele, <span>2020</span>).

Just as the first article in this issue, she ties in with similar analyses of COVID-19 discourses across countries (Lemor &amp; Montpetit, <span>2024</span>; Persson et al., <span>2022</span>) and looks at the discourse in German newspapers to extract information on the positions of political actors and measures their centrality in the discourse network. The findings indicate that those actors that are central in the discourse are characterized by being part of the executive branch of the Länder and federal level and having candidate status. Hence, the polarization of discourse during the COVID-19 pandemic was less an issue of government versus opposition but between legislative and executive branch, whereby crisis communication apparently was also actively used for personal profile-building.</p><p>In the third contribution to this issue, Cantó et al.
