Empirical Modeling of Policy Diffusion in Federal States: The Dyadic Approach

Policy diffusion is a common phenomenon in federal states: indeed, one of the normative justifications of decentralized policy making is that it permits the development and spread of best practices. Following Berry and Berry (1990), event‐history analysis has been the method of choice for the quantitative investigation of policy diffusion, but Volden (2006) has recently introduced a dyadic variant of this method in which units of analysis are not states but, instead, pairs of states. This article discusses the dyadic approach with a particular focus on the diffusion of policies in Switzerland. The goal is not to introduce a new method, but rather to provide a practical overview for researchers interested in using it. The article shows how the method has migrated from the international relations literature to the policy‐diffusion literature, describes the typical structure of a dyadic dataset in a diffusion context, and discusses several modeling issues. The usefulness of the dyadic approach is illustrated empirically with the example of health‐insurance subsidy policies in Swiss cantons.     

What determines UN approval of greenhouse gas emission reduction projects in developing countries?

The Clean Development Mechanism (CDM), established by the Kyoto protocol, can generate substantial rents for project participants via the sale of Certified Emission Reductions. For this reason, supposedly technical decisions about the approval of CDM methodologies and about the registration of projects may be driven by benefits to specific countries or interest groups. Our econometric analysis of data for about 250 methodologies and about 1000 projects discussed by the CDM Executive Board (EB) so far, suggests that indeed, along with formal quality criteria, political-economic variables determine the final EB decision.     

Vom ungeliebten Störenfried zum akzeptierten Paradigma? Zum Stand der (Neuen) Politischen Ökonomie in Deutschland

This contribution presents the German state of the art of economic approaches to politics. First, the basic model, the research areas, and the analytical tools used by these approaches are briefly introduced. Second, for each sub-field of political science, the German contribution is presented in relation to the international state of the art. While German scholars hesitated to engage in public choice and positive political theory in the beginning, we nowadays find many contributions from this perspective in the fields of electoral studies, the European Union, and veto player analysis.     

The Individual-Level Determinants of Exiting German Parties

With respect to explaining declining party membership, the question who leaves political parties and why has so far been neglected. This article aims to fill this gap by applying Hirschman’s theory of “Exit, Voice, and Loyalty” to both current and former party members, and at combining it with the resource model of political participation. We find that neither individual resources nor reasons for discontent are sufficient to explain the different reactions to discontent, but that the exit-voice-loyalty model has a certain explanatory power.     

United Nations Peacekeeping Decisions: Three Hierarchies,Upward Mobility and Institutionalised Inequality among Member States

ABSTRACT

This article explores the multiple and evolving hierarchies shaping UN decisions on peacekeeping operations. Three hierarchies—based on Security Council membership, financial assessments, and troop contributions—currently distribute influence over these decisions among UN member states. These hierarchies differ in their relationship to global stratification patterns, and in the states they empower. Their gradual “layering” has thus expanded the potential for upward mobility within the UN: states unable to increase their influence in one hierarchy can seek empowerment in another. Yet the UN peacekeeping case also highlights the limitations of hierarchy layering as an equalising mechanism in international organisations. New hierarchies supplement rather than replace older ones, and the degree to which they challenge existing rankings varies. Moreover, each new hierarchy inherently highlights, and creates institutional consequences for, a particular type of inequality among states. Consequently, hierarchy layering is best understood as recalibrating rather than eliminating institutionalised inequality in international organisations.     

A case of failed interregionalism? Analyzing the EU-ASEAN free trade agreement negotiations

In 2007, the European Union (EU) and the Association of the Southeast Asian Nations (ASEAN) started interregional negotiations on a free trade agreement, which failed 2 years later. Relying on document analysis and elite interviews with officials from the EU and ASEAN’s members, this article addresses why and the extent to which the interregional negotiations failed. By rooting the theoretical model in a power-based approach, the analysis demonstrates that the EU has attempted to secure its economic and regulatory power in Southeast Asia. In striving for such power, interregionalism was initially the intuitive way because the EU perceived ASEAN as a cohesive bloc. However, the EU’s ambitious vision for comprehensive agreements clashed with the actual heterogeneity of ASEAN member states. The failure of the interregional approach is, thus, a result of the EU’s delicate balance between political and economic interests in Southeast Asia, which it pursues with trade-specific issues.
