Regional inequalities and transnational solidarity in the European Union

Amid the eurocrisis, scholars and policy makers sought to establish an EU-wide layer of social policy, aiming to ensure common standards through the EU and to provide a degree of common social protection. While public support for European social policy has been extensively studied, we don’t know how regional (i.e., subnational) inequalities relate to preferences for European social policy. We analyse the effect of regional differences in socio-economic and institutional contexts on public preferences for European social policy in general and support for European unemployment insurance in particular. Combining original survey data collected in 2018 in 12 European countries with regional-level economic and political indicators, we find that regional-level self-interest impacts individual preferences but that the effect is not always clear-cut. Contrary to expectations, people in richer regions are more supportive of EU social policy than people in poorer regions, while citizens of politically more autonomous regions tend to have a generally more positive view of EU social policy. A conjoint experiment on support for different policy variants of European unemployment insurance sheds light on these counterintuitive findings: Citizens in richer regions are indeed more supportive of EU-level social policy, but only when it has limited redistributive implications and instead affects standards; conversely citizens in poorer regions are willing to forego their op- position to EU social policy for redistributive programs.
