Uniformity and Differentiation in European Regulation

Research project led by Theresa Kuhn, Maria Weimer and Jonathan Zeitlin, supported by Amsterdam Center for European Studies

This interdisciplinary research project tackles the challenge of reconciling functional pressures for uniform rules in integrated markets with diversity of preferences, institutions and conditions across member states. How far can such diversity be accommodated through flexible or ‘experimentalist’ forms of governance, as opposed to differentiated regimes in which some member states push ahead while others opt out, or unresolvable deadlocks that may block or even reverse the integration process itself? And what are the implications of each of these scenarios for the effectiveness and legitimacy of European governance?

In the aftermath of the eurozone crisis, ambitions for European unemployment insurance have been high on the political agenda. However, are European citizens ready to share the risk of unemployment crises hitting their countries? This project sheds light on this crucial, yer unresolved question by conducting a conjoint survey experiment on public support for European unemployment insurance among a representative sample of nearly 20.000 respodents in 13 European member states. The conjoint experiment studies citizen preferences for actual policy proposals that vary on six dimensions: (1) generosity, (2) country-level conditionality, (3) cross-country redistribution, (4) governance, (5) impact on taxes, and individual conditionality. Our results show that policy design matters for public support. Findings also highlight differences across countries, and socio-economic and ideological differences among citizens. Most importantly, fundamental opposition to cross-border risk sharing is confined to a small segment of the European population.

The project strives to examine the dynamic relationship between elites and masses in policy-making about common defense in the multi-level European system. Two overarching questions lie at the heart of the project: what and how do elites and European mass publics think about greater (European) defense, security, and military integration? More specifically, the project wants to achieve the following objectives: (1) study what mass publics and security elites understand by “common defense”, (2) estimate the level of public support or opposition to a vast array of possible forms of defense integration across Europe, including assessing support for some form of European military, (3) explore differences in citizen perceptions and preferences across regions within the EU, (4) identify individual-level values, predispositions, attitudes, and demographic factors that shape support or opposition to defense integration, (5) examine how elite cues, social cues, and real-world events affect defense integration attitudes, (6) analyze the interplay of media content, individual media exposure, and mass opinion towards European defense and security integration, and (7) evaluate how (and how accurately) elites perceive mass opinion toward European defense and security integration, and vice versa. The project combines qualitative (elite interviews) and quantitative research (surveys with embedded experiments and media content analysis) to examine what factors affect European security policy preferences. The primary focus lies on France, Germany, Italy, and Great Britain, four countries that will play important roles in European defense integration

In the context of the European sovereign debt crisis, this project analyses transnational solidarity in the European Union by asking to what extent European citizens are willing to share with people from other member states. To this aim, I conduct laboratory and survey experiments in several European countries. In the laboratory experiments, participants earn some money and then have to take different sets of decisions: (1) Keep the money or donate part of it to charities that help long-term unemployed people in their own country or in other member states; (2) keep the money or share it with other participants that are either from their own country or from other member states. By doing so, I can assess whether participants are equally generous towards recipients from other European countries, and who are the people that are most willing to share with other Europeans. The population-based survey experiments allow testing whether relationships found in the lab also hold for the wider population.
