  • Facets of Crises: How Problem Indicators and Public Perceptions Affect Policy Change

    Open Access•Constantin Kaplaner, Alexa Lenz et al.•ARTICLE•Policy Studies Journal•2026

    Crises are widely acknowledged as catalysts for policy change. Yet, our understanding of the policy effects of crises remains limited. Why do only some crises lead to major changes, while significant policy changes also occur during seemingly non‐crisis periods? This paper addresses this gap by distinguishing between two critical “components” of crises: objective problem pressures and public perceptions. We argue that these components often co‐oc…

  • Administrative overload and policy triage: Causal evidence from the introduction of the Acid Rain Program in the United States

    Open Access•Constantin Kaplaner, Christoph Knill et al.•ARTICLE•Journal of Public Administration…•2025•References: 22

    Recent research suggests that additional public policies can sometimes decrease overall policy effectiveness rather than improve the problem-solving capacity of the state. This occurs when new policies are not supported by additional administrative capacities, leading to an overburdened administration. Public authorities handle the increased workload by employing “policy triage,” which involves reallocating resources among different policies. Des…

  • Policy integration in the European Union: Mapping Patterns of Intersectoral Policy-Making Over Time and Across Policy Sectors

    Open Access•Constantin Kaplaner, Christoph Knill et al.•ARTICLE•Journal of European Public Policy•2025•Cited by: 8•References: 57

    Policy integration has become an important principle guiding public policy development. Despite its prominence, we lack comprehensive knowledge of the exact degree of policy integration and its variation across policy sectors and time, mainly due to the lack of systematic measurement approaches. We address this shortcoming by (1) developing a novel measure that evaluates the intersectorality of legal acts and (2) assessing its development in the …

  • Laws as blades: A conceptual framework of legislative design

    Open Access•Steffen Hurka, Stefanie Rueß et al.•ARTICLE•Policy Sciences•2025•References: 15

    Legislation shapes every aspect of public life and stands at the core of governance. Despite sustained attention on a variety of aspects of legislation, we still lack a comprehensive and integrated framework of legislative design. To address this gap, we introduce a novel conceptual framework that analyzes legislative design along two dimensions— versatility and precision —using six indicators: objects, subjects, instruments, dilution, derogation…

  • Policy complexity and implementation performance in the European Union

    Open Access•Maximilian Haag, Steffen Hurka et al.•ARTICLE•Regulation & Governance•2024•Cited by: 12•References: 36

    This study examines the relationship between the complexity of EU directives and their successful implementation at the national level. Moving beyond the state‐of‐the‐art, we propose a comprehensive framework considering structural, linguistic, and relational dimensions of policy complexity. We argue that policy complexity entails higher transaction costs, hindering effective implementation. Using a novel dataset covering roughly 1000 directives …

  • Proposal complexity and report allocation in the European Parliament

    Open Access•Steffen Hurka, Maximilian Haag et al.•ARTICLE•European Union Politics•2023•Cited by: 3•References: 46

    Experience and loyalty have been identified as major explanations for why Members of the European Parliament (MEPs) are selected as committee rapporteurs in the European Parliament. Yet, existing research implicitly assumes that these explanations operate in isolation of what the report is about. In this article, we hypothesize that the effects of experience and loyalty on MEPs’ chances to become rapporteurs should be conditioned by the complexit…

  • Coping practices and the spatial dimension of authority design

    Open Access•Constantin Kaplaner, Yves Steinebach•ARTICLE•Public Administration Review•2023•References: 26

    Frontline implementers develop coping practices to deal with implementation burdens. Unfortunately, we have only limited knowledge of how widespread and systematic these practices are applied. This paper provides a comprehensive analysis of the enforcement activities carried out in the context of the European Union Industrial Emission Directive, relying on a quantitative data set that summarizes the information from more than 2000 inspection repo…

  • Policy complexity in the European Union, 1993-today: Introducing the Euplex dataset

    Steffen Hurka, Maximilian Haag et al.•ARTICLE•Journal of European Public Policy•2022•Cited by: 34•References: 25

    Despite its importance for the sustainability of democratic governance, policy complexity is still an understudied phenomenon. What makes policies complex? Why are some policies more complex than others? And what are the consequences of this complexity for the political, economic and societal level? These questions still lack answers, which is both due to a lack of conceptual clarity and a lack of suitable data. In order to tackle these challenge…

  • Why We Should Use the Gini Coefficient to Assess Punctuated Equilibrium Theory

    Open Access•Constantin Kaplaner, Yves Steinebach•ARTICLE•Political Analysis•2022•Cited by: 6•References: 12

    Punctuated Equilibrium Theory posits that policy-making is generally characterized by long periods of stability that are interrupted by short periods of fundamental policy change. The literature converged on the measure of kurtosis and L-kurtosis to assess these change patterns. In this letter, we critically discuss these measures and propose the Gini coefficient as a (1) comparable, but (2) more intuitive, and (3) more precise measure of “punctu…

  • Are popular and powerful committees more representative? Evidence from the ninth European Parliament

    Open Access•Steffen Hurka, Constantin Kaplaner•ARTICLE•Research & Politics•2020•Cited by: 1•References: 8

    The standing committees of the European Parliament perform crucial policy-making functions and, accordingly, the question of how they are composed assumes great relevance. Unlike previous studies, which primarily looked at committee assignments from the perspective of individual MEPs, we assess the representativeness of entire committees by comparing their preference distributions with those we find in the plenary on the left/right and pro/anti E…

  • Singing Together or Apart? Comparing Policy Agenda Dynamics within International Organizations

    Louisa Bayerlein, Constantin Kaplaner et al.•ARTICLE•Journal of Comparative Policy…•2020•Cited by: 8•References: 17

    Are there substantial differences between the issues an IO’s decision-making body agrees upon and the issues the organization’s administrative body is dealing with in practice? Or are member states and the administration singing (to) the same tune? To tackle these questions, this article explores agenda congruence in three single-purpose organizations using methods of quantitative text analysis. The explorative empirical analysis shows that both …
